Saga da Amazônia
(Vital Farias)
Era uma vez na Amazônia a mais bonita floresta Mata verde, céu azul, a mais imensa floresta No fundo d'água as Iaras, caboclo lendas e mágoas E os rios puxando as águas Papagaios, periquitos, cuidavam de suas cores Os peixes singrando os rios, curumins cheios de amores Sorria o jurupari, uirapuru, seu porvir Era fauna, flora, frutos e flores Toda mata tem caipora para a mata vigiar Veio caipora de fora para a mata definhar E trouxe dragão-de-ferro, pra comer muita madeira E trouxe em estilo gigante, pra acabar com a capoeira Fizeram logo o projeto sem ninguém testemunhar Pra o dragão cortar madeira e toda mata derrubar Se a floresta meu amigo, tivesse pé pra andar Eu garanto, meu amigo, com o perigo não tinha ficado lá O que se corta em segundos gasta tempo pra vingar E o fruto que dá no cacho pra gente se alimentar? Depois tem o passarinho, tem o ninho, tem o ar Igarapé, rio abaixo, tem riacho e esse rio que é um mar Mas o dragão continua a floresta devorar E quem habita essa mata, pra onde vai se mudar? Corre índio, seringueiro, preguiça, tamanduá Tartaruga: pé ligeiro, corre-corre tribo dos Kamaiura No lugar que havia mata, hoje há perseguição Grileiro mata posseiro só pra lhe roubar seu chão Castanheiro, seringueiro já viraram até peão Afora os que já morreram como ave-de-arribação Zé de Nana tá de prova, naquele lugar tem cova Gente enterrada no chão Pois mataram índio que matou grileiro que matou posseiro Disse um castanheiro para um seringueiro que um estrangeiro Roubou seu lugar Foi então que um violeiro chegando na região Ficou tão penalizado que escreveu essa canção E talvez, desesperado com tanta devastação Pegou a primeira estrada, sem rumo, sem direção Com os olhos cheios de água, sumiu levando essa mágoa Dentro do seu coração Aqui termina essa história para gente de valor Pra gente que tem memória, muita crença, muito amor Pra defender o que ainda resta, sem rodeio, sem aresta Era uma vez uma floresta na Linha do Equador
“Sem conseguir resolver para onde olhar durante todo esse tempo, Dafé se
admirou de haver tanta ciência naquela gente comum, se admirou também de
nunca ter visto nos livros que pessoas como essas pudessem possuir
conhecimentos e habilidades tão bonitos, achou até mesmo a mãe uma
desconhecida, misteriosa e distante, em seu saber antes nunca testemunhado.
Quantos estudos não haveria ali, como ficavam todos bonitos fazendo ali suas
tarefas, agora também ela ia ser pescadora! Até pouquinho, estivera meio
convencida, porque ia ser professora e portanto sabia muito mais coisas do que
todos eles juntos, mas se via que não era assim. Tinha gente que pescava o peixe,
gente que plantava a verdura, gente que fiava o pano, gente que trabalhava a
madeira, gente de toda espécie, e tudo isso requeria grande conhecimento e
muitas coisas por dentro e por trás desse conhecimento - talvez fosse isto a vida,
como ensinava Vô Leléu, quanta coisa existia na vida! Que beleza era a vida,
cada objeto um mundão com tantas outras coisas ligadas a ele e até um pedaço
de pano teve alguém para prestar atenção só nele um dia, até tecê-lo e acabá-lo e
cortá-lo, alguém que tinha conhecimentos tão grandes como esses pescadores e
navegadores, mas já se viu coisa mais bonita neste mundo do nosso Deus? Dafé
sentiu até um pouco de vontade de dançar, deu uns tapinhas acelerados na borda
do barco, deu uns gritinhos, sapateou de emoção, correu de um lado para o
outro, vendo aqui o peixe que vinha, ali o anzol sendo iscado, acolá o plaf-plaf
das chumbadas engolidas pela água − mas oba, oba, oba, esta vida não é uma
beleza cheia de novidades? Agora ela também queria trabalhar de navegadora e
pescadora. Mas também queria ser professora. E o que é que ela queria mesmo?
Queria ser tudo, isso sim! Porque cada ofício tem o seu conhecimento da vida,
quantos lados tem a vida, vô Leléu?”

A onda do mar leva
A onda do mar traz
Quem vem pra beira da praia, meu bem
Não volta nunca mais

RESUMO
Sistemas socioecológicos (SSE) são os complexos sistemas que abarcam tanto a dimensão
social (humana) quanto a ecológica (biofísica). Ambas dimensões são igualmente importantes
e funcionam como um sistema interdependente, no qual alterações em uma dimensão afetam a
outra. Para que o manejo de recursos naturais seja sustentável a longo prazo, faz-se necessário
garantir a integridade do SSE do qual tais recursos fazem parte. Portanto, é preciso considerar
tanto as dimensões biofísicas quanto as humanas desse sistema, incluindo seus componentes
sociais, econômicos, políticos e culturais. O manejo colaborativo (comanejo) é uma das
ferramentas que vem sendo utilizada na busca pela conciliação entre as distintas dimensões
dos SSE. Nesta tese, o manejo do pirarucu (Arapaima sp.) foi utilizado como um estudo de
caso para fornecer subsídios e incentivos ao desenvolvimento de sistemas de manejo de
recursos naturais mais eficazes, que busquem conciliar o sucesso das múltiplas dimensões do
SSE. Para tanto, foram abordadas três esferas distintas e complementares: ecológica, social e
cultural. No primeiro capítulo, demos maior enfoque na esfera ecológica ao avaliarmos as
tendências históricas de mudança na abundância e no tamanho dos pirarucus através das
percepções de 247 pescadores de 67 comunidades localizadas nos rios Juruá e Purus, dois
grandes tributários do rio Amazonas. No segundo, priorizamos a esfera social e abordamos, a
partir de dados quantitativos provenientes de entrevistas com 143 mulheres de 54
comunidades do rio Juruá, o potencial manejo do pirarucu em promover uma maior equidade
de gênero na pesca, além de outros benefícios sociais decorrentes. No terceiro, a esfera
cultural ganhou maior destaque ao utilizarmos dados de literatura para mostrar como o
manejo com foco em espécies culturalmente importantes pode ser uma ferramenta de grande
potencial para promover benefícios ecológicos e sociais, conciliando conservação da
biodiversidade com qualidade de vida de povos locais.

ABSTRACT
Socioecological systems (SES) are the complex systems encompassing both the social
(human) and the ecological (biophysical) dimensions. These dimensions are equally important
and function as an interdependent system, in which changes in one dimension affect the other.
For ensuring the long-term sustainability of natural resources management, it is necessary to
guarantee the integrity of the SES from which these resources are part. Therefore, it is
necessary to consider both the biophysical and the human dimensions of this system,
including its social, economic, political and cultural components. Collaborative management
(comanagement) is one of the available tools for reconcile the different dimensions of SES.
Here, the arapaima (Arapaima sp.) comanagement was used as a case study to provide
subsidies and incentives for the development of more effective natural resource management
systems. Three different and complementary spheres were addressed: ecological, social and
cultural. In the first chapter, we focused on the ecological dimension by evaluating the
historical trends of arapaima abundance and size based on the perceptions of 247 fishermen
from 67 communities located in the Juruá and Purus rivers, two major tributaries of the
Amazon River. In the second chapter, we prioritized the social sphere and showed, based on
interviews with 143 women from 54 communities on the Juruá River, that arapaima
comanagement has the potential to promote greater gender equity in fisheries. In the third
chapter, the cultural dimension was prominent as we used literature data to show how
comanagement focusing on culturally important species can be a potential tool to promote
ecological and social benefits, reconciling biodiversity conservation with local welfare.

INTRODUÇÃO GERAL
Sistemas socioecológicos (SSE) são aqueles compostos tanto por dimensões biofísicas quanto
humanas, incluindo componentes econômicos, políticos, sociais e culturais (Berkes e Folke,
1998; Berkes 2011). As dimensões biofísicas e humanas são igualmente importantes e
funcionam como um sistema interdependente, no qual ao mesmo tempo em que as ações
humanas afetam os sistemas biofísicos, os fatores biofísicos também afetam o bem-estar
humano (Berkes 2011). Assim, apesar de muitas vezes serem tratadas separadamente, essas
dimensões deveriam ser consideradas inseparáveis, uma vez que estão totalmente
interrelacionadas e se afetam mutuamente (Hilborn e Walters, 1992; Berkes et al. 2001;
Kooiman et al. 2005; Cochrane e Garcia, 2009). Diversos autores argumentam que os
sistemas socioecológicos deveriam ser utilizados como unidade de análise nos estudos sobre
sustentabilidade e que o manejo de recursos naturais, para ser efetivo e realmente sustentável
a longo prazo, precisa focar em garantir a integridade desses sistemas e de suas múltiplas
dimensões (Francis et al. 2007; Cochrane e Garcia 2009; Berkes 2011).
O manejo colaborativo (comanejo) é uma das ferramentas utilizadas na busca pela
conciliação entre a dimensão biofísica e humana dos SSE (Folke et al. 2005; Kooiman et al.
2005; Armitage et al. 2007). Em termos gerais, o comanejo refere-se ao compartilhamento do
direito de tomada de decisão e de controle sobre o uso dos recursos entre os usuários e o
Estado e/ou demais instituições envolvidas (Jentoft, 1989; Pomeroy and Berkes, 1997). As
iniciativas de comanejo passaram a ocorrer mais expressivamente a partir da década de 1980,
representando uma alternativa ao regime de livre acesso (open access) e à centralização do
controle nas mãos do Estado (Cleaver, 1999; Gutiérrez et al., 2011). A partir desse sistema
mais inclusivo, acredita-se que o manejo tenda a apresentar maior eficiência, pois as regras
passam a ser mais legítimas para os usuários e a refletir melhor as condições do local,
resultando em propostas mais coerentes e em uma maior predisposição ao cumprimento dos
acordos (Jentoft, 2000; Jentoft et al., 1998; McClanahan et al., 2011, 2006). Ao cumprir os
acordos, os usuários promovem uma série de benefícios ecológicos, os quais gerarão
benefícios diretos e indiretos para eles próprios.
No caso dos SSEs da pesca artesanal de pequena escala, que é responsável por cerca
de metade da produção de todo pescado do mundo e emprega aproximadamente 25 milhões
de pescadores (FAO 2014), o manejo colaborativo parece representar uma ótima alternativa
para a sustentabilidade, uma vez que esse tipo de pesca é difícil de ser manejada com
eficiência a partir de um sistema de governança centralizado (McClanahan et al., 2009;
4
Costello et al. 2012). Essa dificuldade se deve especialmente ao caráter multiespecífico da
pesca, ao uso de distintos petrechos para captura e à falta de pontos de desembarque
definidos, características que limitam a coleta de dados e a capacidade de fiscalização
(McClanahan et al., 2009). Assim, diversos países têm buscado tornar a governança da pesca
de pequena escala mais participativa, estimulando o desenvolvimento de regimes de comanejo
(Alcala and Russ, 2006; Gelcich et al., 2010; Olsson et al., 2008).
A bacia Amazônica é a rede de drenagem com a maior área e a maior diversidade de
peixes do planeta (Junk et al. 2007). O pescado é a principal fonte de proteína animal para os
povos amazônicos, que apresentam o maior consumo per capita médio deste produto no
Brasil e um dos maiores do mundo, chegando a atingir um consumo médio de 800 g de
peixe/pessoa/dia em algumas localidades (Isaac e Almeida, 2011). Estimativas indicam que a
Amazônia responde por aproximadamente 60% de toda a produção da pesca extrativa
continental do Brasil (MPA, 2013), porém grande parte do que é pescado provavelmente
sequer chega a ser registrado formalmente. A crescente demanda comercial tem resultado em
diversos casos de sobrepesca na região amazônica, especialmente de espécies de alto valor e
ciclo de vida longo (Castello et al., 2014). Portanto, o desenvolvimento de formas alternativas
de manejo pesqueiro, a exemplo dos sistemas de comanejo, é uma das maneiras de se tentar
buscar melhorias para este cenário.
Dentre as iniciativas de comanejo na Amazônia vem se destacando bastante nos últimos
anos o manejo colaborativo do pirarucu (Arapaima spp.). O pirarucu é um dos maiores peixes
de água doce do mundo e um elemento de grande importância ecológica, econômica e cultural
na Amazônia. Esse peixe costumava ser associado a uma única espécie (Arapaima gigas;
Castello and Stewart, 2010), mas é atualmente mencionado como Arapaima spp. devido às
incertezas quanto à distribuição de múltiplos congêneres (Stewart 2013a,b; Castello et al.
2014; Watson et al. 2016). Durante todo o século XIX e início do século XX, o pirarucu foi o
principal recurso pesqueiro comercial da Amazônia Brasileira (Veríssimo 1895; Mérona
1993), o que levou à sua sobre-exploração em muitas áreas e a casos de extinções locais
(Castello et al. 2014). A pesca do pirarucu foi sendo, então, gradualmente proibida nos
estados da Amazônia a partir do final dos anos 1990, porém os índices de pesca ilegal se
mantiveram sempre muito altos diante da fiscalização ineficiente na região (Cavole et al.,
2015; Castello and Stewart 2010). Neste contexto, o manejo colaborativo do pirarucu surgiu
como uma alternativa para conciliar a recuperação dos estoques de pirarucu com a sua pesca
sustentável, despertando o engajamento dos povos locais e estimulando o cumprimento das
regras e a fiscalização protagonizada pelos próprios comunitários (Castello et al., 2009).

A primeira experiência de manejo do pirarucu começou em 1999, na Reserva de
Desenvolvimento Sustentável Mamirauá, localizada na bacia do rio Solimões, estado do
Amazonas. Ao longo dos anos, a experiência mostrou resultados promissores e, após
comprovado seu sucesso, o modelo foi aceito pelo Instituto Brasileiro do Meio Ambiente e
dos Recursos Naturais Renováveis (IBAMA) como um sistema de manejo a ser
potencialmente replicado em outras áreas do estado, o que gerou a possibilidade da pesca
legal do pirarucu sob determinadas condições (Instrução Normativa Nº 1, de 1º de junho de
2005, Amazonas; Decreto Estadual Nº 36083, de 23 de julho de 2015, Amazonas). O manejo
do pirarucu proliferou-se na região e atualmente abarca mais de 3000 famílias, de mais de 450
comunidades rurais do Amazonas (IBAMA, comunicação pessoal). Outros estados, como
Acre e Rondônia, também estabeleceram normas permitindo a pesca do pirarucu se
desenvolvida dentro dos moldes de um plano de manejo aprovado pelos órgãos competentes
(Instrução Normativa Nº 1, de 30 de maio de 2008, Acre; Instrução Normativa Nº 2, de 13 de
maio de 2019, Rondônia).
O manejo do pirarucu é baseado em um sistema de cotas anuais, calculadas de acordo
com o número de indivíduos presentes em cada local a ser pescado. O número de indivíduos é
determinado anualmente a partir de um método de contagem inspirado no conhecimento local
dos pescadores e testado através de métodos científicos (Castello, 2004). A captura máxima
permitida pelo IBAMA é de 30% do total de indivíduos adultos contados (Decreto Estadual
Nº 36083, de 23 de julho de 2015, Amazonas), mas a cota concedida pode variar dentro desse
limite de acordo com critérios estabelecidos pelo IBAMA (IBAMA, comunicação pessoal).
Para obter aprovação do plano de manejo, as comunidades precisam delinear o zoneamento
dos seus corpos de água, determinando quais serão destinados ao uso contínuo (subsistência
e/ou comercial) e quais serão protegidos. Dentre os protegidos, deve-se incluir tanto lagos
destinados à pesca da cota anual de pirarucu (sem nenhum outro uso no restante do ano)
quanto lagos de proteção integral (sem nenhum tipo de uso ao longo de todo ano). Os
comunitários são responsáveis por garantir a fiscalização efetiva dos lagos protegidos para
evitar eventos de pesca ilegal nos mesmos (Decreto Estadual Nº 36083, de 23 de julho de
2015, Amazonas).
As iniciativas de manejo do pirarucu vêm promovendo a recuperação e aumento dos
estoques desse peixe em diversas regiões (Campos-Silva and Peres, 2016; Castello et al.,
2009; Petersen et al., 2016; Viana et al., 2007). No entanto, pouco se sabe acerca das
tendências históricas das populações de pirarucu na Amazônia, devido à deficiência de
monitoramento dos estoques e do desembarque pesqueiro. O acompanhamento sistemático
6
restringe-se apenas às áreas de manejo, nas quais são realizadas estimativas anuais de
abundância (contagens) de acordo com exigências do IBAMA. Tais áreas, porém, são
geograficamente limitadas e abrangem apenas uma pequena porção da distribuição geográfica
do pirarucu (Castello e Stewart 2010). Além disso, mesmo nessas áreas, o monitoramento
normalmente é restrito somente aos lagos protegidos, enquanto nos lagos de uso
(subsistência/comercial) as populações de pirarucu não costumam ser estimadas, ainda que
esses lagos façam parte da área de zoneamento da unidade de manejo (IBAMA, comunicação
pessoal). Vale ressaltar, ainda, que as áreas monitoradas possuem apenas registros recentes,
pois as iniciativas de manejo começaram a se espalhar apenas a partir dos anos 2000, o que
significa que não há dados disponíveis para avaliarmos as mudanças temporais dos estoques
em uma escala de tempo maior. No entanto, tendências temporais são particularmente
relevantes no caso de espécies historicamente exploradas que estejam experimentando
aumentos recentes, como é o caso do pirarucu, a fim de evitar que a magnitude da
recuperação seja sobre-estimada (Lotze et al. 2011; McClanachan et al. 2012). Neste sentido,
buscamos acessar tendências históricas de mudança na abundância e no tamanho dos
pirarucus a partir das percepções de pescadores locais. Diversos estudos ressaltam o potencial
dos pescadores em ser uma importante fonte de dados, especialmente nos casos em que há
pouca informação proveniente de monitoramentos sistemáticos (ex.: McClanachan et al.,
2012; Sáenz-Arroyo and Revollo-Fernández, 2016; Thurstan et al., 2015). A partir de dados
obtido em entrevistas com pescadores, então, buscamos responder às seguintes questões
centrais: as populações de pirarucu estão se recuperando tanto nos lagos protegidos quanto
nos demais? Nos locais onde percebe-se aumento dos estoques, já foram alcançados os níveis
populacionais do passado mais distante que conseguimos alcançar? O tamanho dos indivíduos
também vem sofrendo modificação ao longo das últimas décadas?
Em paralelo aos aspectos ecológicos é preciso olhar também para as demais esferas do
comanejo do pirarucu, uma vez que o mesmo corresponde a um sistema socioecológico e,
portanto, é composto por múltiplas dimensões inter-relacionadas. Alguns estudos apontam
para os benefícios econômicos gerados pelo manejo, já que a atividade resulta em uma
significativa renda extra para famílias rurais que normalmente possuem poucas alternativas de
geração de renda (Amaral, 2009; Campos-Silva and Peres 2016; Castello et al. 2009). No
entanto, as demais dimensões do manejo do pirarucu têm sido amplamente negligenciadas nas
pesquisas acerca da atividade. Pouco se fala, por exemplo, sobre os impactos sociais do
comanejo, apesar de haver indicações de que tal dimensão é diretamente afetada pela
atividade (Campos-Silva and Peres 2016). A dimensão social é uma faceta importante do
7
sucesso de qualquer SSE, e a conciliação entre os benefícios sociais e ecológicos é crucial
para a sustentabilidade do sistema a longo prazo. Além disso, a forma como os usuários
percebem as vantagens e desvantagens do sistema é determinante na maneira como irão agir,
o que influenciará o sucesso ecológico e, consequentemente, as demais dimensões do sistema
(Pollnac et al. 2010). Um exemplo importante de efeito social a ser investigado aqui refere-se
à participação das mulheres na cadeia produtiva da pesca do pirarucu, uma atividade que até
então era restrita aos homens (CTF, observação pessoal). Em diversas iniciativas de manejo
do pirarucu as mulheres participam da atividade e são financeiramente retribuídas pelo tempo
que investiram nela, o que para muitas parece tratar-se de algo inédito no universo das
atividades pesqueiras (CTF, observação pessoal). Esse aspecto chama especial atenção pelo
fato de a equidade de gênero ser um dos Objetivos de Desenvolvimento Sustentável propostos
pela Organização das Nações Unidas para serem utilizados como metas pelas nações (ONU
2015). Assim sendo, nos perguntamos: existe diferença no acesso à renda proveniente da
pesca para mulheres localizadas em comunidades onde há e onde não há comanejo do
pirarucu? O comanejo está contribuindo para uma maior equidade de gênero no universo da
pesca?
Outra esfera muito pouco explorada nos estudos sobre o manejo do pirarucu é a
dimensão cultural, ainda que esta dimensão pareça estar diretamente relacionada ao sucesso
das iniciativas (CTF, observação pessoal). As pesquisas com enfoque no manejo e nos seus
resultados, comumente atribuem o sucesso das iniciativas ao engajamento comunitário
(Castello et al. 2009; Petersen et al. 2016; Campos-Silva and Peres 2016), mas os fatores que
promovem tal engajamento não costumam ser abordados. Seria a importância cultural do
pirarucu, além da econômica, um gatilho para motivar o interesse e o envolvimento dos povos
locais com as iniciativas de manejo voltadas para esse peixe? O manejo com foco em espécies
de grande importância cultural poderia ser visto como uma potencial ferramenta para conciliar
conservação da biodiversidade com melhoria da qualidade de vida de povos locais? Essa
ferramenta poderia ser aplicada em outros contextos do mundo?
Esta tese busca responder essas perguntas e preencher tais lacunas de conhecimento,
avançando em esferas distintas e complementares do SSE do comanejo do pirarucu e na
relação entre elas. No primeiro capítulo, damos maior enfoque à esfera ecológica ao
avaliarmos as tendências históricas de mudança na abundância e no tamanho dos pirarucus, a
partir das percepções de 247 pescadores de 67 comunidades localizadas nos rios Juruá e
Purus, dois grandes tributários do rio Amazonas. No segundo, priorizamos a esfera social e
abordamos, a partir de dados quantitativos provenientes de entrevistas com 143 mulheres de
8
54 comunidades do rio Juruá, o potencial do manejo em promover uma maior equidade de
gênero, além de outros benefícios sociais decorrentes. No terceiro, a esfera cultural ganha
maior destaque ao utilizarmos dados de literatura para mostrar como o manejo com foco em
espécies culturalmente importantes pode ser uma ferramenta de grande potencial para
promover benefícios ecológicos e sociais, conciliando conservação da biodiversidade com
qualidade de vida de povos locais.

ABSTRACT
Even tough wildlife has been intensely exploited for centuries, studies addressing the current
status of the populations often ignore their past conditions. Humanity is commonly deceived
by the “shifting baseline syndrome”, and each generation subconsciously accept as a baseline
the environmental conditions that occurred in their youth. Moreover, most studies addressing
the shifting baseline are restricted to the marine realm, while freshwater ecosystems have
gone largely disregarded. However, freshwaters may have been even more drastically
impacted than marine or terrestrial systems, and the shifting baseline syndrome likely affects
our current evaluations and management targets. Here we attest to this idea by addressing
temporal trends of the arapaima (Arapaima sp.), an iconic fish that used to be the most
important commercial fishery resource in the Brazilian Amazon until face overfishing
scenarios in many areas and some local extinctions. Through a comprehensive survey
encompassing 247 interviews in 67 communities of two major tributaries of the Amazon
river, we assessed fishers’ perceptions on the relative changes of arapaima stocks over the last
~70 years. We show that arapaima populations are recovering in some areas, but still
declining in others. Moreover, even where the stocks are increasing, they have not yet reached
its past abundance. We explore the nuances of our findings, and address specific strategies to
be adapted to use fishers’ perceptions for accessing data on banned species in data-poor
scenarios worldwide.

INTRODUCTION
Humans have impacted global fauna and flora over millennia. Most agree that we live now in
the Anthropocene era, a geologic time in which human activity has emerged as a global force
transforming the entire Planet along relatively short time-scales (Ellis, 2015; Zalasiewicz et
al. 2010). Over the past 500 years, humans have triggered a wave of wildlife declines that
may be comparable in both rate and magnitude with the five previous mass extinctions of
Earth’s history (Dirzo et al., 2014). As we scaled up from hunter-gatherers to modern
societies, the need for more intensive exploitation of natural resources has increased, together
with the drastic impact on the ecosystems (Crosby 2000).
Despite the acknowledged historical overexploitation of wildlife, studies addressing
the current status of the populations often ignore their past conditions. There is an underlying
assumption that only recent data on composition and abundance exist, and that historical data
are either nonexistent or not good enough to use in rigorous assessments (Pinnegar and
Engelhard, 2008). As such, scientists are commonly deceived by the “shifting baseline
syndrome” – that is, each generation subconsciously accept as a baseline the environmental
conditions that occurred at the beginning of their career (Pauly, 1995; Sheppard 1995). As one
generation replaces another, people’s perspectives change such that they fail to appreciate the
extent of past modifications (Sáenz-Arroyo et al., 2005). The gradual shift of the baseline
results in the use of inappropriate reference points to evaluate changes and to define
conservation targets (Jackson et al., 2001; Pauly, 1995).
Several studies have addressed the shifting baseline phenomenon over the last years,
using different methods to obtain historical information, such as archaeological remains,
genetic analysis, historical inventories, historical reports, trade records, and logbooks
(Pinnegar and Engelhard, 2008). Local ecological knowledge (LEK; Berkes et al., 1994;
Johannes, 1998) has also proven to be a powerful and cost-effective tool to increase our
understanding on population dynamics, especially when historical data is not available
(Mcclenachan et al., 2012; Sáenz-Arroyo and Revollo-Fernández, 2016; Thurstan et al.,
2015). Even though those unconventional sources of information have different degrees of
bias and may be methodologically more difficult to use than modern standardized data, they
should not be discarded or discredited on account of that (Jackson et al., 2001; Mcclenachan
et al., 2012; Sáenz-Arroyo and Revollo-Fernández, 2016). Worldwide, studies incorporating
data from non-traditional sources have revealed important processes of long-term changes and
enabled valuable insights into wildlife management that would otherwise not be possible
(Early-Capistrán et al., 2018; Jackson et al., 2001; Kittinger et al., 2015; Lotze and Worm,
15
2009; Mcclenachan et al., 2012; McClenachan et al., 2015; Torre et al., 2006). The more we
access population trends over the longest time period possible, the more we prevent the
widespread shifting baseline syndrome.
The shifting baseline syndrome was first identified in studies on marine fisheries
science and most studies addressing the phenomenon are still restricted to this realm.
Freshwater environments remain largely neglected in the field, although historical
exploitation of freshwater fauna was also intense and overharvesting rapidly devastated stocks
of the most economically valuable species (Humphries and Winemiller, 2009). The effects of
overexploitation in freshwaters may have been even more drastic than in marine or terrestrial
systems, mainly due to the constrained, more accessible nature of freshwater environments
(Humphries e Winemiller 2009). Indeed, a recent study on the resilience of Amazonian fauna
to the massive 20th century international fur/skin trade, showed that whereas freshwater
species suffered drastic population collapse, terrestrial species did not, partially due to the
persistence of adequate spatial refuges enabling source-sink dynamics (Antunes et al. 2016).
The profound effects of the past decimation of freshwater populations have gone largely
disregarded worldwide, and the shifting baseline syndrome likely affects our perceptions on
recent freshwater degradation and our evaluations of restoration targets (Humphries e
Winemiller 2009).
Here we step up this idea by assessing the historical trends of an iconic fish from the
Amazon basin: the arapaima (Arapaima sp.). Arapaima is one of the largest freshwater fish on
Earth, and used to be the most important commercial fishery resource of the Brazilian
Amazon during the 19th and early 20th century (Mérona, 1993; Veríssimo, 1895). Such severe
pressure led to an overfishing scenario, and to the consequent prohibition of arapaima harvest
in the 1990s (Castello et al., 2014). Yet, the effectiveness of the prohibition was hindered by
high levels of illegal harvest due to insufficient compliance and surveillance (Castello and
Stewart, 2010; Cavole et al., 2015). Since the 2000s, an arapaima co-management model has
been gradually established in different areas, promoting the increase of local populations
(Campos-Silva and Peres, 2016; Castello et al., 2009; Petersen et al., 2016). A remarkable
lack of historical data on arapaima stocks, however, limits our understanding on the
populations’ changes over time. Temporal trends are particularly relevant in such cases of
historically exploited species that are experiencing recent increases, otherwise the magnitude
of the recovery can be overestimated (Lotze et al. 2011; McClenachan et al. 2012). For
banned species exposed to high levels of illegal harvest, as is arapaima, evaluating the
16
population trends is also crucial to verify if the prohibition was enough for ensuring recovery,
or if further measures may be needed.
Through a comprehensive survey encompassing 247 interviews in 67 communities of
two major tributaries of the Amazon river, we assessed fishers’ perceptions on the relative
changes of arapaima populations over the last ~70 years. We show that although arapaima
stocks have been promisingly increasing in some areas, they have not yet reached its past
abundance, nor is the recovery geographically distributed across the studied regions. We
discuss the nuances of our findings and the broad implications of our study, which could serve
as a model to other researches in data-poor scenarios worldwide.
MATERIAL AND METHODS
Study area
The study was conducted in the Brazilian Amazon, specifically in the Juruá and in the Purus
rivers (Fig.1), two major tributaries of the Amazon river. Both are whitewater rivers and have
their origins in the Andes, from where they transport large amounts of nutrient-rich sediments
(Junk et al. 2011). The whitewater rivers deposit their sediments in large floodplains, locally
known as várzeas. The várzeas are highly fertile and covered with productive terrestrial and
aquatic herbaceous plant communities and floodplain forests, which function as a nursery and
feeding area for many fish species (Junk et al., 2011). The Juruá and the Purus rivers are very
productive in terms of fishing, and part of their fishery production is destined to Manaus, the
capital of Amazonas state and the largest Amazonian city. Both basins have Sustainable-Use
Protected Areas (herein PAs), a park category with the goal of reconciling natural resource
conservation with the maintenance of local people traditional ways of life. We surveyed
communities located along ~1500 km of the lower and middle Juruá river, and ~150 km of the
lower Purus river (Fig. 1). The surveyed communities were located either inside or outside
PAs. The PAs included in the study were the Middle Juruá Extractive Reserve (RESEX
Médio Juruá; 5º 33’ S, 67º 42’ W; ~287,000 ha), the Uacari Sustainable Development Reserve
(RDS Uacari; 5º 43' S, 67º 46' W; ~633,000 ha) and the Lower Juruá Extractive Reserve
(RESEX do Baixo Juruá; 3º 30’ S, 66º 05’ W; ~188,000 ha) in the Juruá basin, and the
Piagaçu-Purus Sustainable Development Reserve (RDS-PP; 4º 45' S, 61º 07' W; ~1.008.000
ha) in the Purus basin (Fig. 1). The inhabitants of all surveyed communities have similar
livelihoods, based mainly on fisheries, slash-and-burn agriculture and non-timber forest
17
products (Newton et al., 2012). Fishing is one of the main sources of income to the local
communities in both studied regions (Newton et al., 2012).

Arapaima and its fishery in the Brazilian Amazon
Arapaima (locally known as pirarucu; Fig. 2) used to be considered a single species
(Arapaima gigas; Castello and Stewart, 2010) but is currently referred to as Arapaima spp.
due to uncertainties regarding the distribution of multiple congeners (Castello et al., 2013;
Stewart, 2013a, 2013b; Watson et al., 2016). This fish has great ecological, economic and
cultural importance in the Amazon, playing a central role in the livelihood of many
Amazonian peoples since pre-Columbian times (Aparicio, 2014; Murrieta, 2001; Prestes-
Carneiro et al., 2016). Arapaima fishing used to be a specialized activity, restricted to only a
few specialists in each community, since its capture was done mainly with a harpoon and
required advanced technical skills. This fishing also implied in a profound Local Ecological
Knowledge on arapaima and its ecology, which was passed down through generations,
normally from father to son. Since the early 2000s, arapaima can only be legally harvested
within specific arapaima co-management schemes subjected to the approval of the Brazilian
Environmental Agency (IBAMA). In such schemes, arapaima fishing has turned into a
18
collective activity, with a totally different arrangement than the historical and traditional
fishing.
Arapaima co-management is featured by local people and authorized by IBAMA. The
model is based on a quota system set yearly according to the fish abundance within the
management areas (Castello et al., 2009). The maximum allowed quota corresponds to 30%
of the total arapaima adults (> 1.5 m in length) existing in the area. The abundance is annually
estimated by local people through a standardized protocol based on direct visual counts
(Castello, 2004). This is possible because arapaima is an obligate air-breather that comes to
the surface every ~15 min. IBAMA only releases the first fishing quota to the community
after three consecutive annual counts, and depending on the increases on arapaima stocks over
this time. The quota is allocated as a one-off annual harvest, normally lasting from a few days
to a month. To be granted IBAMA’s approval to manage arapaima, the community needs to
zone its water bodies, specifying which lakes will be destined to protection (hereafter
“protected lakes”), to subsistence fishery (hereafter “subsistence lakes”) or to commercial
fisheries (hereafter “open access lakes”). The protected lakes encompass both no-take lakes
and lakes where there is no fishing all over the year but the one-off arapaima annual quota
fishing. The inclusion of protected lakes is mandatory, and the communities need to establish
a local vigilance system to preclude poaching. They are also required to send an annual report
to IBAMA, with detailed information on each step of the co-management, such as the
arapaima counting, harvest (including the weight, sex, and gonadal stage of each individual
captured) and commercialization. All these steps follow specified protocols, and are subjected
to different types of oversight. Arapaima co-management is currently happening in ~ 450
communities within the Amazonas State, where the studied communities are located (IBAMA
unpublished data; Sup.Fig.1). In the other Amazonian states, the establishment of co-
management initiatives is still insipient. The engagement of local people in the arapaima co-
management has ensured its success and several consequent positive ecological and
socioeconomic benefits, including the significant recovery of arapaima populations, the
generation of income to rural families and the maintenance of cultural practices (Campos-
Silva and Peres, 2016; Castello et al., 2009; Petersen et al., 2016; Viana et al., 2007; Amaral,
2009). Despite the prohibition of arapaima harvest outside a co-management scheme, in both
the Juruá and the Purus basins there is a local understanding that arapaima may be harvested
for local consumption, and the species is often caught for this purpose (CTF personal
observation).

Data sampling
Our data is based on semi-structured interviews with 247 fishers, 123 from the Juruá and 124
from the Purus basin. Fishers were from 54 communities of the Juruá basin (16 inside and 38
outside PAs) and 13 of the Purus basin (9 inside and 4 outside PAs). The interviews were
conducted in 2016 (August-November) in the Juruá river, and in 2017 (October-November) in
the Purus river. In each community, we used snowballing techniques to identify the fishers
who were believed by the community members to have a good knowledge on arapaima
(expert arapaima fishers). Particular attention was given to the identification of elderly expert
fishers in each community. We explained the goals of our study to each potential interviewee
and asked for their voluntary participation. All those who consented to participate were
included in the research. All interviewees were men, which is related to the fact that arapaima
fishing used to be a male activity in the Amazon. Over the last years, women have been
included in some of the co-management initiatives, but their participation is normally
20
restricted to the post-harvest activities only (see chapter 2) and our questions for this study
required experience with arapaima harvest. The questionnaire used for the interviews included
questions on: (i) the name of the lakes where the interviewee used and uses to go fishing (and
since when); (ii) the category of each lake (protected, open access or subsistence lake); (ii)
how many adult arapaima (> 1.5 m) he estimate he would approximately see in the most
abundant part of each cited lake if he watched the lake for 20 min in the period when he
started fishing; (iii) how many he would currently see if he watched the same area for 20
minutes; (iv) the weight of the largest arapaima he has ever caught in his life, and when was
it. For this last question (iv), we asked for the largest fish caught out of the co-management
harvest, since the fishing done within the co-management scheme is collective and many
interviewees could mention the same fish (pseudoreplication). Additionally, we used direct
observation in the fishing communities (including during arapaima fishing) and spontaneous
open questions to better understand nuances of arapaima fisheries and local specificities.
Data analysis
Studies have pointed out the importance of addressing trends, rather than absolute values, to
properly use LEK as one of the available tools to understand the dynamics of wild
populations from a historical perspective (e.g. Saenz-Arroyo and Revollo-Fernandez 2016).
As such, quantifying arapaima population and establishing specific individual lengths is not in
the scope of this study. Instead, we tried to evaluate the relative temporal trends in arapaima
abundance and size according to fishers’ perceptions and records.
Arapaima sightings
For evaluating abundance trends, we used fishers’ estimates of arapaima sightings as a proxy
of arapaima relative abundance. Studies using interviews to assess data on fish abundance
normally focus on fishing captures, mainly on the interviewees’ best catch or catch per unit
effort (e.g. Coll et al., 2014; Early-Capistrán et al., 2018; Tesfamichael et al., 2014). A
reduction in the catch over time likely indicates a decline on the species abundance, if the
commercial demand for the species has not changed nor fishers have any other reason for
having reduced their catch. In the case of banned species, however, acquiring information on
current catches may be challenging, since those who are still harvesting the species will likely
not feel at ease to openly expose data on illegal catches. That is why we decided to use
arapaima sightings instead of arapaima catches.
21
We firstly calculated the rate of change of arapaima sightings by dividing the number
of arapaima each interviewee estimated to see in the past by the number he estimated to
currently see in the same area. The rate was calculated by: log (past sightings+0.5) – log
(present sightings+0.5). This rate was used as the response variable, and the year when the
interviewee started to fish in the area was the predictor. To not overweight the perception of
fishers who cited a higher number of lakes, we summarized an average rate per interviewee
by each lake category. The subsistence lakes were excluded from the analyzes because this
category encompasses a wide range of actual uses, from cases where the lake functions
similarly to a protected lake (e.g. only a few families, from a certain community, fish there
and exclusively for household consumption) to cases where it functions similarly to an open
access lake (e.g. several families, from various communities, fish there and eventually for
small-scale commercial purposes). The analyses were therefore restricted to the protected and
open access lakes only. Most protected lakes are located inside PAs, while the open access are
common both inside and outside PAs. Data was analyzed separately for the Juruá and the
Purus basins, and for each lake categories. The database we acquired from the interviews
started in different periods in each analyzed case: from the 1940s in the case of the Purus
open access lakes; from 1950s in both protected and open access lakes of the Juruá; and from
1960s in Purus protected lakes.
We used loess regressions to fit smooth curves between the variables to evaluate
general trends of arapaima relative abundance over time in each case. Loess is a powerful
locally weighted regression for fitting smooth curves to empirical data (Jacoby, 2000). It is a
non-parametric method whose procedure is a fairly direct generalization of traditional least-
squares methods for data analysis (Cleveland, 1979). As such, loess tries to find a curve of
best fit without assuming the data must fit a certain distribution shape. It depicts the “local”
relationship between the response and predictor variables over parts of their ranges, which
may differ from a “global” relationship determined using the whole data set (Cleveland 1979).
Instead of estimating parameters like a and b in y = ax +b, it focuses on the fitted curve. The
fitted points and their standard errors are estimated with respect to the whole curve rather than
a particular estimate. The overall uncertainty is measured as how well the estimated curve fits
the population curve (Jacoby 2000).
In the graphs showing the relative changes on arapaima sightings over time, the Y axis
corresponds to the rate of change calculated as log (past sightings/present sightings). When Y
= 0, the number of arapaima seen in the past (numerator) is equal to the number of arapaima
seen in the present (denominator), since log (1) = 0. For a constant present arapaima sighting,
22
an inferior Y value for someone who started to fish in the year X+1 compared to someone
who started in the year X, indicates that the person who started before (in X) got to see more
arapaima in the beginning of his career than the person who started later (in X+1), i.e. the
downward curve indicates a decline in the past number of arapaima. Once the curve shows a
point of inflexion and goes up, it means that people who started to fish after this year used to
see more arapaima in the beginning of the career than people who started just before, i.e. the
upward curve indicates an increase in the past number of arapaima. In both the downward and
upward curves, if Y values are below zero, it indicates that the rate (i.e. past/present) is
inferior to 1, since log (x < 1) = < 0. In this case, people have been sighting a higher number
of arapaima currently than when they started fishing, regardless if arapaima populations were
declining or increasing in the past. As such, in the hypothetical case of having more arapaima
currently then in the whole period from 1940s onwards (i.e. from when we have data), we
would see the whole curve below zero. In a hypothetical case where arapaima populations
would not have changed since the 1940s, we would have seen a straight line at Y = 0.
Arapaima size
To evaluate trends in arapaima size over time, the largest arapaima caught was used as a
proxy of arapaima maximum size. As such, the weight of the largest arapaima ever caught by
each interviewee (out of co-management harvest) was used as the response variable, and the
year when the fish was caught was the predictor. Loess regressions were used to fit smooth
curves between the response and predictor variables, and data was analyzed separately for the
Juruá and the Purus basins. As opposed to the case of arapaima sightings, the relationship
between arapaima size and the predictor was monotonic in both basins, which allowed us to
use a Spearman correlation to verify the relationship between the variables.
RESULTS
Arapaima sightings in protected lakes
Both rivers, Juruá (red line) and Purus (blue line) showed similar trends regarding the
temporal changes on arapaima sightings in protected lakes (Fig 3). In both basins, arapaima
sightings declined from the beginning of the database (1950s) until the mid-1990s, when it
began to stabilize and then to increase around 2005 (Fig 3). The lines cross the zero in 1975
and 1965 for the Juruá and the Purus river, respectively (Fig 3), indicating that people who
started fishing after these dates saw on average more arapaima in recent years than in the
23
beginning of their career, whereas those who started fishing before these turning points
believe that arapaima has not yet recovered its past abundance. The 10-years difference
between the two basins could either indicate that the arapaima declined first in the Purus or
that the recent arapaima recovery was stronger in the Purus than in the Juruá. Yet, the former
hypothesis is more likely since arapaima recovery has been similar in the protected lakes of
both basins (Campos-Silva et al. in press; Petersen et al., 2016). The curve representing the
Purus is always below the one of the Juruá (Fig. 3), which indicates that the rate between the
past and present arapaima sightings is smaller in the Purus. Thus, assuming that the current
abundance of arapaima is similar in both basins, the lower line corresponds to fewer past
arapaima sightings in the Purus compared to the Juruá. The lines of both basins show a major
decline in the first decades and a smoothed decline from the 1980s on, which could indicate
either a reduction on fishing pressure thenceforth or stock depletion.

Arapaima sightings in open access lakes
The general pattern of change is different between the open access lakes from the Juruá (red
line) and the Purus (blue line; Fig. 4). In the Juruá, the line does not cross the zero, which
means that the interviewees as a whole used to sight more arapaima in the past than currently,
regardless of when the person started fishing (i.e. the stocks have not started increasing yet).
The line approaches a downward straight line, which indicates a sharp decline on arapaima
sightings over time (Fig. 4). In contrast, in the Purus basin the line crosses the zero around
1975, indicating that only those who began their career before this year used to sight more
arapaima in the past, while those who started later have been sighting more arapaima lately
than in the beginning of their careers. The Purus curve stabilized around 1995 and began to
rise by 2005 (Fig. 4).

Arapaima size
The average size of the largest arapaima caught by the interviewees (disregarding those
harvested within a co-management scheme) has declined over the last decades in both the
Juruá (rho = - 0.50, p < 0.0001) and the Purus (rho = - 0.53, p < 0.0001, Fig. 5). The data is
scanty before the 1970s, which is likely related to a common time lag between the period
when the interviewees started their career as fishers and the period when they began fishing
arapaima. In the interviews, fishers often attributed such time lag to the fact that arapaima
fishing demands high technical expertise and profound acquired knowledge on arapaima. The
data scarcity in the first decades of the study hampers the proper adjustment of the trend lines,
and results in large confidence intervals at the beginning of the time series (Fig. 5).
Nevertheless, there is a clear declining pattern in both basins for the subsequent period to
which there is more data. The average size of the largest arapaima is always greater in the
Juruá than in the Purus basin. For instance, in 1990 the largest arapaima caught had in average
~175 kg in the Juruá compared to ~115 kg in the Purus. In 2000, the average was ~155 kg in
the Juruá and ~95 kg in the Purus (Fig. 5). However, the shape of the lines indicates a sharper
decline in the Juruá than in the Purus along the surveyed period (Fig. 5).

DISCUSSION
Our results show a severe decline on arapaima populations throughout the mid-20th century in
both the Juruá and the Purus basins. Although the populations have been increasing since the
beginning of the 2000s, the recovery is not necessarily widespread within each basin. In the
Juruá, for example, arapaima populations are increasing in the protected lakes but are still
declining in the open access lakes. In both the Juruá and the Purus, arapaima average
maximum size (disregarding those caught in management schemes) has been declining over
the last decades.
Our data is limited to the mid-20th century onwards because the oldest people in the
communities in general only began fishing in the 1950s. Nevertheless, sparse historical
archives indicate that arapaima fishing pressure dates way back before this period. The
explorer Robert Schomburgk, for example, mentioned in his book published in 1840 that
“there are extensive [arapaima] fisheries for supplying the different towns, and great
quantities are sent to Para, where it is preferred to the fish salted on the North American
coast, and commands a higher price.” (Schomburgk, 1840). In 1854, a periodical where
governmental acts of the Amazonas state were issued, published a note establishing the value
of provincial tax for arapaima commercialization (Estrella do Amazonas 1854). In 1895, José
Veríssimo mentioned in his book that “arapaima fishery occupies the first position among the
Amazonian fisheries, according to any possible economic criteria” and that “the arapaima is
the basis of Amazonian nourishment” (Veríssimo 1895, p. 28). Such historical evidences
suggest that the pressure over arapaima stocks was already high in the 19th century. Indeed,
in 1941 the ichthyologist Manuel Nunes Pereira mentioned in a report that arapaima was no
longer as abundant as before in most lakes of the Purus basin (Nunes Pereira 1941). He
considered that the species was endangered by this time and that some harvest restrictions
would be crucial to ensure arapaima perpetuation (Nunes Pereira 1941). Therefore, the
decline observed here in the early years representing the relative changes on arapaima
sightings over time (Fig. 3 and 4) is the result of an intense exploitation lasting surely for
more than a century before the 1950s.
Changes on arapaima sightings in the protected lakes
In the Purus, fishers who started fishing after 1965 tended to generally mention more
sightings recently in the protected lakes than they used to see in the past, while in the Juruá
this is the case only for fishers who started fishing one decade later (Fig. 3). Such 10-years
disparity between the two basins is likely due to historical differences in local fishing
27
pressure. The Purus river is much closer to Manaus (Fig. 3), the largest city in the entire
Amazon, which favored the commercialization of products from this basin. The access from
Manaus to both basins is by boat, and it takes one and five days to reach the Purus and the
Juruá, respectively (travelling throughout day and night). The journey along the Juruá also
takes longer, since it is the most winding river in the world (IBGE 2019). For instance, six
days are needed to navigate along the Juruá River from the surveyed communities closest to
Manaus to those more distant (Fig. 1). Despite the lack of historical landing data, there is
evidence that from 1976 to 1978 the Purus responded for 16-19% of the total annual
Amazonas fishing catch and had ~6500 registered fishers, while the Juruá responded for 5%
and had ~1200 registered fishers (Petrere 1983, 1985). Within this period, ~900 annual
fishing trips from Manaus, the main consumer city, were done to the Purus as opposed to only
~100 to the Juruá (Petrere 1983). Such higher fishing pressure in the Purus likely led to an
earlier depletion of the local stocks compared to the Juruá, and that is probably why the
current scenario of arapaima abundance in the Purus is better than the one back in 1965, while
this is not yet the case for the Juruá. The difference in the historical fishing pressure between
the two basins, and the presumed better condition of the past stocks in the Juruá, may also
justify why the rate between the past and present arapaima sightings is always higher in the
Juruá (Fig. 3).
The rise of the curves representing the relative temporal changes on arapaima
sightings in the protected lakes (Fig. 3) is likely related to the establishment of arapaima co-
management initiatives in the studied regions. Arapaima annual counts began in 2005 and
2007 in the studied areas of the Juruá and the Purus, respectively (IBAMA, unpublished data).
To start the counts, the communities needed to have previously zoned their water bodies and
converted some of them into no-take lakes. Therefore, most lakes currently labeled as
protected were converted into such category around this period, although not all
simultaneously, since the co-management started in a few communities and was gradually
adopted by others (IBAMA, unpublished data). Interviewees commonly mentioned that, even
though some lakes were already labeled as protected previously to the establishment of the
arapaima co-management (within the establishment of the Protected Areas), compliance was
not as effective as in the context of arapaima co-management. The co-management
represented a paradigm shift, in which local people became an important part of the arapaima
conservation without giving up financial gains. They felt stimulated by the recovery of this
culturally important fish that was hitherto almost disappearing, and felt proud of being the
driving force of such recovery (Campos-Silva et al. 2016). The co-management was a great
28
stimulus for local compliance and surveillance against poaching, which resulted in the
consequent increase of the stocks (Campos-Silva et al. 2016; Castello et al. 2009).
Changes on arapaima sightings in the open access lakes
Arapaima sightings have been also increasing in the open access lakes of the studied area in
the Purus basin, whereas they are continuously declining in the Juruá (Fig. 4). Such difference
may be consequence of the geographical distribution of our sampling in each basin. While in
the Juruá the surveyed communities were distributed across ~1500km of the river bank, in the
Purus they were much more concentrated, along ~150 km of the river bank and in adjacent
regions (Fig. 1). Therefore, the surveyed communities in the Purus, and the lakes used by the
interviewees, were much closer to each other than in the Juruá. The geographical proximity
favors arapaima spillover from the protected to the open access lakes (Campos-Silva et al.
2019). The spillover is possible because the lakes become connected by floodplain forests and
river channels during the high-water season, enabling arapaima lateral migration through
them (Castello et al. 2008). Arapaima move some kilometers (~ 30 km) during the high-water,
and tend to come back to the same region when the waters level drops (Campos-Silva et al.,
2019). In this process, the individuals may disperse to nearby lakes and reproduce on them
(Campos-Silva et al. 2019). As our survey in the Purus was geographically restricted to areas
with or close to arapaima co-management, many of the open access lakes mentioned by the
interviewees are likely affected by such arapaima annual migration. In the Juruá, however,
our comprehensive survey included several areas located far from arapaima co-management,
where the species struggles to recover in the absence of spillover from protected lakes
concomitant with high levels of poaching.
The wide media repercussion of the arapaima recovery promoted by the arapaima co-
management may give the impression that arapaima is recovering across the entire Amazon,
which is probably not true. Our findings from the Juruá are likely a good sample of the
Amazonian reality as a whole, since most of arapaima original distribution is not covered by
co-management initiatives (Sup.Fig.1) and their positive impact is thus geographically limited
as well. On places exempted from the co-management initiatives, or from its indirect effects,
the historical overexploitation of arapaima stocks may be increasingly aggravated by high
levels of poaching. For instance, 77% of all arapaima landed in Santarém (a major Amazonian
city) was estimated to be illegal, which corresponds to the highest rate of illegal fishing ever
reported in the global literature and to more than four times the world average (Cavole et al.
2015). Therefore, arapaima may be still facing a widespread declining condition, as reinforced
29
by our results (Fig. 4). Findings from studies addressing the effects of arapaima co-
management also support this idea, since their comparison between adjacent areas with and
without arapaima co-management unanimously shows that arapaima stocks continue to
decline (or stabilize at very low densities) in the absence of arapaima co-management, despite
dramatically increasing in the areas with co-management (Campos-Silva et al. 2016; Petersen
et al. 2016). The only data systematically collected regarding arapaima abundance is the one
from arapaima counts within the co-management schemes, and these counts are mostly
restricted to the protected lakes. Yet, arapaima stocks should be monitored in a broader
geographical scale, especially considering the strong evidence suggesting that simply banning
its fisheries on paper without assuring enough enforcement is not effective in ensuring
arapaima recovery. We also suggest that partnerships between areas with and without
arapaima co-management could increase the range of the co-management effects and
potentiate the spill-over effect. The positive result of such partnerships would be important
not only ecologically but also for the local food security and the maintenance of cultural
values associated to the arapaima.
Changes in arapaima size
Changes in arapaima size over time showed here reinforce its continued overexploitation (Fig.
5). Even tough large individuals are still often captured within the co-management harvest
(CTF and JVCS personal observation), such harvest is normally restricted to the protected
lakes, wherein people do not fish throughout the year except for the one-off annual quota
catch. Protected lakes likely concentrates greater densities of large individuals due to the
strong local surveillance on theses lakes concomitant with the high site fidelity of migrating
arapaima (Campos-Silva et al. 2019). Hence, the probability of finding larger individuals in
protected lakes is likely much greater than in the other lakes, where there are far less arapaima
and they are often captured before reaching large sizes. The data from the interviews probably
refers to individuals caught in non-protected lakes, since fishing in protected lakes is not
allowed outside a co-management scheme, and local surveillance against poaching in these
lakes is normally strong. As such, the declining pattern observed both in the Juruá and the
Purus rivers may be explained by the continued fishing pressure over arapaima out of the
protected lakes. Therefore, similarly to the abundance case, data on arapaima size coming
exclusively from the co-management reports can give us the false illusion that arapaima is
increasing in size all over the Amazon, which may not be true, as suggested by our results. To
the best of our knowledge, even within the co-management areas there is no certainty that
30
arapaima is increasing in size, since the arapaima weight data sent yearly to IBAMA was not
publically analyzed. Studies should be done in order to evaluate the trends on arapaima size
caught in the co-management harvests, and the possibility of restricting a maximum allowed
size for the individuals captured ought to be considered.
The shifting baseline syndrome and the use of fishers’ perceptions for obtaining
information on banned, data-deficient species
Arapaima fishing was banned in the 1990s due to evidence suggesting that the species was
overexploited all over the Amazon. Nevertheless, such evidence was mainly based on direct
observations from researchers and conservationists, since systematic data on arapaima
monitoring or on landing records was absent. Such lack of historical data favors the shifting
baseline syndrome, not only among fishers but among scientists as well, and our perceptions
on the species recovery may consequently become biased and detached from historical reality
(Pauly 1995). Places where monitoring is scarce often concurring with those where
surveillance is deficient. Such unfavorable scenario is highly common in developing
countries, which controversially host most global biodiversity hotspots (Myers et al., 2000)
and most of the world’s rural poor, who depend directly on natural resources for subsistence
and to support local economies (Fisher and Christopher, 2007). Therefore, monitoring the
species and ensuring their perpetuation is both ecologically appealing and critical to maintain
food security and social stability (Adams, 2004; Adenle et al., 2015)
We showed that the shifting baseline is present among Amazonian fishers. Those who
recently began their careers often perceive arapaima stocks as plentiful nowadays in the
protected lakes, while those who started to fish in the 1950-1960s generally claim that
arapaima used to be far more abundant in the past. Such difference reinforces the importance
of accessing and outreaching the historical conditions of the stocks. Shifting baselines among
fishers might, for example, negatively influence their behavior regarding restrictive measures,
since they may not perceive any need to change their ways (Bunce et al., 2008). In the
absence of monitoring data, as in the arapaima case, interviews with users may be the only
source of information to access and evaluate the historical trends of the species. Even though
it may be challenging to incorporate local knowledge into scientific analyses (Huntington
2000; Johannes et al. 2000), that knowledge can offer important insights into the former
conditions of the stocks and ecosystems (Johannes 1981), especially where historical records
are scant. Importantly, when the generation of the eldest people have died, their perception
about how the environment once looked will be gone forever (Sáenz-Arroyo et al., 2005).
31
Here we estimated the abundance trends of a banned species based on fishers’
perceptions, without needing to ask the interviewees about their captures. Even though it is
possible to build trust with the communities and get access to data from illegal activities, such
process demand time and may be unfeasible in many contexts worldwide. Asking about
peoples’ notions, instead of catches, is a less-invasive way of accessing information on a
banned species, which will likely result in a higher number of people keen to participate in the
research. In our case, for example, by asking about arapaima sightings, we enabled a much
more comprehensive survey, encompassing fishers who fish arapaima illegally and would
honestly expose it, fishers who would not expose it (or would lie about the quantities) and
fishers who respect the ban and do not fish arapaima anymore. Moreover, the non-need to
build trust with the communities enable a more comprehensive survey, since data can be
obtained across a broad geographical scale in a shorter period of time.
Studies addressing banned species throughout the world could adapt our method to try
to evaluate the relative changes of the species abundance over time. We acknowledge that
arapaima offers the natural convenience of being easily seen, as it needs to go to the surface to
breath and normally stays restricted to the lakes during the low-water season. Nevertheless,
other questions could be used for other contexts, as for instance “How many [species popular
name] do you think you could catch on a fishing day in [place name] (i) currently and (ii) in
the period when you began to fish?” or “If you leave a gillnet for [amount of time] in [place
name], how many [species popular name] do you think you could catch (i) these days and (ii)
in the period when you began to fish?”. Other questions could be used depending on the
particularities of each fishery. Similarly, questions about the size could also be adapted to
other contexts. In our case, data on arapaima size was not a problem because people still feel
free to fish arapaima for household consumption. Where this is not the case, the survey could
be restricted to the abundance, or questions regarding fish size could be adjusted in order to
avoid embarrassment. For instance, instead of the largest fish caught by the interviewee, we
could ask “What is the size of a [species popular name] considered to be large (i) nowadays
and (ii) in the period when you began to fish?” or “When people catch [species popular
name], how large it (i) uses to be nowadays and (ii) used to be when you began to fish?”. In
all cases, designing a proper questionnaire requires reasonable previous knowledge about the
specificities of the context being addressed (e.g. aspects related to the target species, to the
fishing techniques applied, to the habits of the fishers etc.). It is also important to have large
samples and include a reasonable number of interviewees from each age class (Sáenz-Arroyo
et al., 2005). Additional effort may be needed to find elderly people, particularly in
32
developing countries, where populations are often highly skewed towards young people
(Sáenz-Arroyo et al. 2005). Finally, it may be appropriate to not expose how exactly the rates
and trends will be calculated, to not influence interviewees’ answers due to eventual personal
interests in see a certain result.
The method we propose here does not seek to obtain absolute data on the stocks at a
certain point in time, but to assess relative changes over time based on users’ perceptions. The
central idea was to capture their notion on the differences between the present and past stocks
characteristics. For stocks changing over time, as is the arapaima and many others worldwide,
the contrast between the present and the past tend to be different amongst people from
different ages. Modelling this difference is a way to estimate population trends and relative
changes. Such estimation is highly valuable, as it may help reduce the pernicious shifting
baseline syndrome and enable a more coherent and realistic evaluation of the current relative
condition of the stocks within a historical perspective (Pauly, 1995).
CONCLUSION
To avoid the shifting baseline on wildlife management, species need to be monitored and to
have their current data compared with their historical conditions (Pauly, 1995). In the case of
banned species, monitoring is crucial to verify if the prohibition was effective in ensuring
recovery, or if further measures may be needed. This is especially true for places exposed to
high levels of illegal harvest, as is often the case in developing countries (Adams, 2004;
Adenle et al., 2015; Cavole et al. 2015). Controversially, those places often have scarce
population monitoring and a marked lack of historical data. The case addressed in our study is
a real example of that. Despite being the main commercial fishery resource in the Brazilian
Amazon for centuries, arapaima used to be unmonitored, and historical long-term systematic
data on stocks trends is inexistent. Arapaima fisheries became banned in the 1990s, but is
largely poached throughout the Amazon, and there is still no stock monitoring, except for the
restricted areas of co-management.
By interviewing fishers and accessing their perceptions, we were able to obtain
valuable information on arapaima trends for the last ~70 years. We showed that arapaima was
severely declining along the mid-20th century in both the Juruá and the Purus river, two major
tributaries of the Amazon river. Although the populations have been increasing since the
beginning of the 2000s, the recovery is not widespread within each basin. Arapaima increases
seem to be dependent on the presence of protected lakes surveilled by local people, a
condition often related to the establishment of co-management initiatives. Arapaima co-
33
management follows specific protocols, featured by local people and authorized by the
Brazilian Environmental Agency, and has been highly successful in recovering the stocks.
However, the wide media repercussion of such recovery may give the false illusion that
arapaima is recovering across the entire Amazon. Yet, on places exempted from the co-
management, or from its indirect effects, arapaima seems to be still declining, in both
abundance and size. Considering that co-management initiatives cover a very limited portion
of arapaima original distribution, stocks monitoring should encompass a much broader scale
than that of the co-management areas. Moreover, partnerships between areas with and without
arapaima co-management should be stimulated in order to increase the range of the co-
management effects and potentiate the spill-over effect.
The method used to estimate temporal changes on arapaima abundance was innovative
and very appropriate for the case of a banned species, since it was focused on people notions
about the stocks instead of peoples’ fishing captures. This less-invasive approach enables the
participation of a larger number of people, including those who respect the ban and do not
fish anymore, and those who would not reveal their illegal catches. It is also more time
effective, since it is not necessary to invest a long time in building trust to get access to
compromising information. We suggested specific and practical strategies to enable the
adaption of our method to researches in other contexts throughout the world. We strongly
recommend the use of users’ perceptions as a tool to estimate population trends, especially in
the case of banned species exposed to deficient enforcement and high levels of poaching.
Such estimation may help reduce the shifting baseline syndrome and enable a more coherent
evaluation of the current relative condition of the stocks from a historical perspective.

ABSTRACT
Women greatly contribute to fisheries worldwide, representing about 47% of the global
fisheries’ workforce. Yet female fishing roles often go unrecognized, overlooked and
underpaid. In the Brazilian Amazon, arapaima (Arapaima sp.) co-management fisheries,
which began in the early 2000s, represents a change in this scenario. To assess the impact of
arapaima co-management on women recognition in fisheries, we conducted a comprehensive
assessment at 54 semi-subsistence fishing communities (with and without arapaima co-
management), across a ~1,500-km segment of a major Amazonian river. Based on
quantitative data from interviews with 143 local women, we show that arapaima co-
management represents an innovative source of female income from fisheries and a
groundbreaking recognition of women participation in fishing activities. In communities
where arapaima co-management had been established, median female fishing revenue was
US$ 215/yr and the mean probability of women earning income from fisheries was 76%, a
marked difference from the virtually non-existent female fishing income at communities
without arapaima co-management (median = US$ 0; mean probability = 7%). Our results
support that arapaima co-management was the main variable explaining differences in women
fishing income between the study communities. Although many women often participate in
commercial fisheries, arapaima co-management has been the only source of fisheries income
for most of them. We discuss the potential, limitations and broad implications of our case
study, which can serve as a model to be adapted to other fisheries schemes worldwide seeking
to enhance gender equity in fisheries and other extractive economies.

INTRODUCTION
Fishing is often considered a male activity throughout the world. Estimates indicate, however,
that women represent 47% of the global fisheries’ workforce, encompassing about 56 million
jobs in the harvest and post-harvest subsectors (World Bank, 2012). In the harvest sector only,
women account for nearly 14% (8.3 million) of all people directly engaged in fisheries and
aquaculture (FAO, 2018). Indeed, in some regions women contribute to 25-55% of all small-
scale fisheries catch (Harper et al., 2013; Kleiber et al., 2014; Lentisco and Lee, 2015).
Nevertheless, the role of women in fisheries is often unrecognized and overlooked worldwide
(Bennett, 2005; Di Ciommo and Schiavetti, 2012; Gustavsson and Riley, 2018; Harper et al.,
2013; Zhao et al., 2013).
The common misconceptions that women do not participate in fisheries, or that
women’s roles are of little importance, stem directly from a cultural bias in the definition of
what constitutes “work” and “fisheries” (Nadel-Klein and Davis, 1988). Women role in
fisheries does not necessarily correspond to fishing on a boat for days at a time, as men often
do, which may be consequence of cultural constraints limiting female performance and the
time they can be away from home. Women normally need to reconcile their fishing activities
with the domestic ones, since household chores and most of the child rearing are considered a
women responsibility in many traditional cultures (Frockling et al. 2013). This results in
women often limiting their fishing activities to areas close to the household (FAO, 2018;
Lentisco and Lee, 2015), which probably helps explain why they have a great contribution in
the post-harvest sector (FAO, 2018).
The widespread tendency to conceptually limit fisheries to the harvest sector only,
especially when part of commercial fishing, disregards subsistence fishing and other activities
in the fish supply chain, in which women often play an important, but invisible role (Harper et
al., 2017, 2013; Salmi and Sonck-Rautio, 2018; Zhao et al., 2013). Such invisibilization is
undertaken by both men and women, by reinforcing the roles culturally imposed that
undervalue the female’s work while overvalue the male’s (Gustavsson and Riley, 2018;
Koralagama et al., 2017; Yodanis, 2000). This invisibilization also results in women being
unpaid or underpaid, as their participation in fisheries is usually seen as an informal help or as
an extension of the household obligations (Di Ciommo and Schiavetti, 2012; Yodanis, 2000).
The lack of financial recognition may feedback women’s invisibilization in fisheries, since
the value socially attributed to a certain work is commonly related to its remuneration.
Gender equity and women empowerment are one of the Sustainable Development
Goals of the 2030 Agenda for Sustainable Development, set out by the United Nations to
42
guide developing policies (United Nations, 2015). Nevertheless, practical examples of
initiatives and tools to effectively increase gender equity in fisheries are incipient. Here, we
evaluate the potential of a fisheries co-management scheme to substantially increase the
access of women to fishing income, and consequently enhance female recognition and
empowerment. Based on data from a comprehensive sampling, we show an actual example of
how a new management arrangement could enable the inclusion and financial recognition of
women in a fishery that used to be totally dominated by men. We discuss the potentialities,
limitations and broad implications of our case study, which could serve as a model to other
fisheries schemes throughout the world.
METHODS
Study area
The study was conducted in the Juruá River (Amazonas State, Brazil), a major tributary of the
Amazon River. The region has different protected areas, including a few Sustainable-Use
Protected Areas (herein PAs), a park category with the goal of reconciling natural resource
conservation with the maintenance of local people’s traditional ways of life. We surveyed
communities located both inside and outside two contiguous PAs (Fig. 1), the Middle Juruá
Extractive Reserve (RESEX Médio Juruá; 5º 33’ S, 67º 42’ W; ~287,000 ha) and the Uacari
Sustainable Development Reserve (RDS Uacari; 5º 43' S, 67º 46' W; ~633,000 ha). These two
PAs are analogous in terms of local access to institutional support and to sources of income.
All surveyed communities are situated along the Juruá riverbank (Fig. 1), and their inhabitants
have similar livelihoods, based mainly on fisheries, slash-and-burn agriculture and non-timber
forest products (Newton et al., 2012). Fishing is one of the main sources of income to the
local communities in the studied region (Newton et al., 2012).

Arapaima co-management
The fisheries scheme addressed in this study is the arapaima co-management. Arapaima
(Arapaima spp.) is one of the largest freshwater fish in the world, which in the past used to
reach up to 200kg (Gudger, 1943). It is an iconic fish of the Amazonian floodplains, with
great ecological, economic and cultural importance. During the 19th and early 20th century,
arapaima was the most important commercial fishing resource in the Brazilian Amazon
(Mérona, 1993; Veríssimo, 1895), which led to its overfishing in many areas, and to the
consequent prohibition of its harvest in the 1990s (Castello et al., 2014). The effectiveness of
the prohibition was hindered by high levels of poaching (Castello and Stewart, 2010), a
scenario that only started to change in the 2000s, after a co-management model was proposed
by a non-profit organization working in the Solimões River basin (Castello et al., 2009). The
first experiences were successful and the initiatives proliferated throughout the Amazon,
starting in our study area in 2005. Currently, arapaima fishery is still banned by law in
44
Amazonas State, and the species can only be legally fished within a co-management scheme
proposed by local communities and approved by the Brazilian Environmental Agency –
IBAMA (Amazonas, 2005).
Arapaima co-management must follow a model required by IBAMA, which includes
several rules (Amazonas, 2015). The fishery is based on a quota system set yearly according
to the fish abundance within the management areas (Amazonas, 2005; Castello et al., 2009).
The abundance is annually estimated by local people through a standardized protocol that
uses direct visual counts (Castello, 2004). This is possible because arapaima is an obligate air-
breather that comes to the surface every ~15 min (Castello, 2004). The quota is allocated as a
one-off annual harvest, normally lasting from a few days to a month. To be granted IBAMA’s
approval to manage arapaima, the community needs to zone their water bodies, including no-
take lakes, and to establish a local vigilance system to preclude poaching (Amazonas, 2015).
Arapaima co-management generates several ecological and socioeconomic benefits,
including the significant recovery of arapaima populations, the generation of income to rural
families and the maintenance of cultural practices (Campos-Silva and Peres, 2016; Castello et
al., 2009; Petersen et al., 2016; Viana et al., 2007; Amaral, 2009). In some of the
communities, women have officially joined the co-management (Fig. 2), being paid for their
participation, an innovation in an otherwise male dominant fishery.

Women participation in arapaima fisheries
Historically, arapaima fisheries used to be a highly specialized activity, restricted to a few
experts in each locality (Castello et al. 2009). Such specialization comes largely from the
traditional practice of harpooning the arapaima at the moment of aerial breathing (Castello et
al. 2009), which requires high technical skills and enough knowledge on the species behavior.
Arapaima fishery used to be restricted to the men (Castello et al. 2009), likely due to features
of the fishery associated with cultural constraints. For instance, catching arapaima requires
46
great physical strength, a feature normally associated to the figure of the men. Local
Ecological Knowledge (LEK; Berkes 2008) on arapaima is generally handed down from
father to son, which make it naturally more difficult to women to engage in arapaima fishing.
Moreover, arapaima fisheries often involved long displacements and sometimes days away
home, which unable women to reconcile this activity with household duties and childcare
(roles culturally seen as women responsibilities).
With the establishment of the co-management scheme, community members engaged
on it are now required to watch over the water bodies throughout the year; count the arapaima
in the period designed for it; harvest the fishing quota; transport the fish to where they will be
cleaned; clean the fish; register information required by IBAMA for each fish caught (weight,
size, gender, gonadal stage); and transport the fish to the buyer. The last five activities are
concentrated in a short period, as fishing is allocated as a one-off annual harvest, limited by
logistical constraints mainly related to fish conservation (CTF and JVCS, personal
observation). Such new arrangement requires having more people working together in order
to perform all the stages and to enable the catch of the total quota in the available time. With
the local perception of an optimized supply chain based on collective effort, arapaima fishery
was naturally expanded from the dominance of the “arapaima experts” to a communal fishing
system (Castello et al. 2009). In such scenario, women were included in the scheme in some
localities and started to participate on arapaima fisheries (CTF and JVCS, personal
observation). In places without arapaima co-management, the species is not allowed to be
fished but illegal fisheries are widespread in the region and large amounts of arapaima are
illegally captured every year (Cavole et al. 2015). In those cases, arapaima fishery is not
performed as a collective activity, as in the co-management, and is normally restricted to the
men only (CTF and JVCS, personal observation).
Despite the fact that arapaima co-management is currently widespread in the Amazon,
female participation in the initiatives is still geographically limited (IBAMA, personal
communication). Co-management specificities vary from place to place, since the
communities have autonomy to decide some internal rules. For instance, they are free to
decide if they will fish the quota collectively or distribute it among community’s members,
how they will organize the work groups, and how they will share the profits among the
participants. Therefore, while in some places women are participating and having their roles
recognized through financial rewards, in many others they were not included in the scheme
(CTF and JVCS personal observation). Eventually, women may participate to a certain extent
but rather than being seen as workers, they are considered as a voluntary helper (CTF
47
personal observation). The reasons explaining such differences between the various initiatives
across the Amazon are still not clear, due to the lack of studies addressing gender issues on
arapaima fisheries.
Data sampling
Our data is based on semi-structured interviews conducted with 143 women, from 54 fishing
communities along ~1,500 km of the Juruá river. The interviews were conducted in 2016
(August-November). At the time, only communities located inside PAs were engaged in
arapaima co-management. In the two PAs included in the study, seven communities were
undertaking the arapaima co-management. We conducted interviews in six of them; the
seventh had to be excluded due to logistical issues. In total, our sampling included women
from three different contexts: 35 women living in communities undertaking the arapaima
management and located inside a PA (six communities); 37 in communities without arapaima
management but also located inside a PA (10 communities); and 71 in communities without
arapaima management and located outside a PA (38 communities). In each community, we
tried to interview all the women who were available and keen to participate in our research.
We used the same questionnaire for all interviews, wherein we asked the interviewee how
often she used to fish (for either subsistence or commercial purposes); how often she earned
any income from fisheries; and how much she earned (in Brazilian Real – R$) from fisheries
in the previous year (2015). For the women engaged in the arapaima co-management, we also
asked about the activities they carried out; if they participated in the co-management decision-
making; and if they thought the arapaima co-management had brought any changes to the
women. Additionally, we used direct observation in the fishing communities (including
during arapaima fishing) and spontaneous open questions, to better understand nuances of
arapaima fisheries and local specificities.
Data analysis
We restricted our analysis to the income effectively received by the women, although we
acknowledge that subsistence fisheries may have a high indirect economic impact (Harper et
al. 2013). To evaluate if the arapaima co-management was financially including women in
fisheries, we used a Mann-Whitney test to verify if female fisheries income was different
between communities with and without arapaima management. We performed a generalized
linear model (GLM) to evaluate the effect of arapaima co-management on women revenues,
taking into account other variables that we believed could also be affecting female income.
48
The model used may be simplified as: fisheries revenue ~ arapaima management + Protected
Area + woman age, in which the response variable is the income from fisheries whereas the
independent variables are the presence/absence of arapaima co-management, the
presence/absence of a Protected Area (ie, whether the community where the woman lived was
inserted in a PA), and the woman age. A structured relationship between residuals and fitted
values of the GLM model indicated that the independent variables affected the response
variable in a discrete instead of a continuous way. Therefore, we decided to use a binomial
GML. As such, we estimated the effect of the same independent variables on the
presence/absence of female income from fisheries, as following: presence/absence of fisheries
revenue ~ arapaima management + Protected Area + woman age. The model used had good
explanatory power compared to a Null model. Model coefficients were afterwards used to
predict the probability of a woman earn income from fisheries if she lives in a community
with or without arapaima co-management. Such probability was calculated considering that
all other variables would remain constant. Finally, a Spearman correlation was used to verify
the relationship between the total fisheries income and the income from arapaima co-
management only. Cases with total income equal to zero were excluded from this analysis to
avoid inflating the relationship between the two variables. In all the analyses, the income
variable corresponded to the fisheries revenue in the year prior to the interview (2015). Only
the income earned directly by the woman (not by the men) was considered. In all cases, the
amount reported in the local currency (Brazilian real – R$) was converted to American dollars
(US$) using the Purchasing Power Parity (PPP) of the World Bank for the year 2015 (US$ 1
= R$ 1.859; World Bank, 2018). Values with decimal points were rounded up to the nearest
whole number.
RESULTS
Women participation in fisheries
Among the 143 interviewed women, most of them (100; i.e. 70%) fish regularly, a pattern that
is consistent in both the communities with and without arapaima co-management (where 74%
and 69% of the interviewees are used to fish, respectively). Within the 100 women who fish
regularly, the majority fish only for subsistence purposes, while 31% participate in
commercial fisheries (or 15% and 36% in the communities with and without arapaima co-
management, respectively). Among the interviewees who are used to participate in
commercial fisheries, only 32% (10 women) eventually earn any income for their
49
participation in the activity (or 25% and 33% in the communities with and without arapaima
co-management, respectively). The women who participate in the punctual, annual event of
arapaima fisheries but are not used to fish along the rest of the year, or to participate in other
commercial fisheries, or to earn income from them, were not considered in such percentages.
From all interviewed women, 35 and 108 lived in communities with and without arapaima co-
management respectively, and 30 participated in arapaima co-management.
Women income in communities with and without arapaima co-management
There is no difference in female fisheries income between communities with and without
arapaima management if we consider all their income except the revenues from the arapaima
co-management (Mann-Whitney W = 2013, p = 0.1; Fig. 3A). In both community categories,
there is a clear pattern of absence of female income from fisheries (median: US$ 0; 1 st
quartile: US$ 0, 3rd quartile: US$ 0; Fig. 3A). Nevertheless, when we include the revenues
from arapaima co-management in the total female fisheries income, we see a marked
difference in women income between communities with and without arapaima management
(Mann-Whitney W = 533, p < 0.0001; Fig. 3). Whereas in the first, the annual median of
women revenues was US$ 215 (1st quartile: US$ 54, 3rd quartile: US$ 377; Fig. 3), in the
latter it remained at US$ 0 (1st quartile: US$ 0, 3rd quartile: US$ 0; Fig. 3).

When the effects of the three independent variables (presence/absence of arapaima co-
management; presence/absence of PA; and woman age) were analyzed, arapaima co-
management was the only one affecting female income, and the effect was positive (p <
0.0001, z = 4.76; Fig. 4). If all variables remained constant, a woman living in a community
with arapaima co-management would have a mean probability of 76% of earning money from
fisheries, compared to only 7% for a woman living in a place without arapaima co-
management (Fig. 5). Total female fishing income is strongly correlated with female income
from arapaima co-management only (rs 0.75, p < 0.0001; Fig. 6), which further reinforces the
impact of arapaima co-management on women fishing revenues. Indeed, in the subset of
women who have earned any income from fisheries, 77% of them had the arapaima co-
management as the unique source of fisheries income.

Women participation in arapaima co-management
Women participation in arapaima fisheries seems to be a consequence of the shift from the
traditional arapaima fishery to the co-management scheme, which implied in a communal
fishing system based on labor division. In such new arrangement, people no longer need to
master every step of arapaima fishery to work on it; through the labor division, workers can
arrange their selves according to their skills and availability. Furthermore, the wide range of
activities within the arapaima co-management required capacity building. In some cases,
community members with some expertise (e.g. cleaning arapaima) taught those who did not,
whereas in others, outsider local experts were invited to the community to teach a certain skill
(e.g. how to count arapaima based on their LEK but following specific rules imposed by
IBAMA). Women certainly benefitted from such knowledge exchange, which provided them
skills that allowed their inclusion in the co-management.
Female roles and rewards are not necessarily equal among the initiatives, nor always
the same within a certain initiative. Among the six surveyed communities engaged in
arapaima co-management, five had the participation of women (community names: São
Raimundo, Xibauazinho, Toari, Morada Nova and Santo Antônio). In those five communities,
women were normally engaged in cleaning the arapaima, cataloging data of caught fish,
cleaning the common spaces, and cooking for the workers during the quota harvest. In
general, women earn much less than men. The difference between both incomes varied
considerably across the five communities, from around three times to more than 10,
depending on how the community decided to arrange the payments. For instance, in one of
the communities (Toari) women are paid a fixed fee per day, whereas in others they take part
in the profits. In this latter case, women income share varied according to the collective
decisions on how the various activities within the co-management stages would be valued. In
only one community (São Raimundo) women could effectively earn the same value as men.
In all communities, women claimed to participate in the meetings involving arapaima co-
management decision-making. However, they may often feel uncomfortable to expose their
opinions in a male-dominated environment.
When asked whether the arapaima co-management had provided something different
to them, most women talked about the opportunity of making their own money and being able
to invest it as they deemed fit. They were grateful for no longer need to subjugate all their
priorities to those of their husbands. According to one of them: “Now we [women] earn our
own money; before [prior to the arapaima co-management] we did not earn anything”, while
another one said “With the management [arapaima co-management] each one has her own
53
money and spends in whatever she wants. Outside the management, the money [of the
household] is all pulled together. [Now] It is up to us to decide if we want to save the money
from the management to buy something more valuable or if we want to buy something for
ourselves”. To the vast majority (97%), it is the first time they are making any income from
fishery-related activities (and often from any economic activity). The opportunity to learn
new things and acquire new skills (e.g., how to clean the arapaima) was also mentioned as
another important advantage of the arapaima co-management. It was also pointed out the
opportunity of having women and men working together, and of women being able to take
part in an activity that used to be exclusive to the men and which women never thought they
would be involved in. Regardless of the specific reasons, all women expressed great
satisfaction with their inclusion in the arapaima co-management.
DISCUSSION
Most women in the studied region are already engaged in fishing, but mainly for subsistence
purposes. Among the women who participate in commercial fisheries, only a minority receive
any payment for their work, except for the income they make from the arapaima co-
management. In fact, where co-management is in place, women have a much higher median
income than their counterparts in communities with no co-management. This happens because
such scheme usually represents their only opportunity of earning income from fisheries. Such
engagement in co-management also translates into wellbeing, as these women claimed to be
very glad for the opportunity.
Arapaima co-management embodies a groundbreaking novelty in the region by
enabling women direct pay for their participation in a fisheries scheme. This represents more
than transferring rightful money to the women, it is their chance out of invisibility. The
financial recognition through payment for their time and effort invested in the activity helps
close the gap between the historical differences in recognition between fishermen and
fisherwomen. When women cease being a “hidden workforce” in fisheries, the importance of
their role is likely to become more evident to both them and their peers (Zhao et al. 2013).
Furthermore, providing income directly to the woman assigns more autonomy and
power to her (Abrams, 2012). Indeed, as mentioned by several interviewees, they no longer
need to ask her husband for every money they need, and consequently do not need to be
subjected to his endorsement and judgment about the need of that money. In some cases,
having their own money can also eliminate embarrassments, as the women will not need to
expose all their wants and needs. Opportunities of income may also help the women be less
54
vulnerable. For instance, a complete financial dependence can prevent them from leaving an
eventual abusive marital relationship, as we have witnessed in particular cases over the last
years working in the region.
Moreover, the distribution of income within the household may affect the family
expenditure patterns. In general, raising women share of income results in an increased budget
share on food and enhances the family’s nutrient intake and health (Doss, 2005; Hoddinott
and Haddad, 1995; Thomas, 1990). Income controlled by women also benefits children more
than income controlled by men (Lundberg et al., 1997; Thomas, 1990; Ward-Batts, 2008). A
study conducted in Brazil showed that child survival probabilities were almost 20 times higher
when income was controlled by the mother then when it was controlled by the father
(Thomas, 1990). In the UK, alcohol and men’s clothing expenditures decreased in the family
budget when money was transferred from men to women, while toys and women’s and
children’s clothing increased as a share of expenditure (Lundberg et al., 1997; Ward-Batts,
2008). Similarly, a study in Côte d’Ivoire found that an increased female share of income
reduced the household money spent on alcohol and cigarettes (Hoddinott and Haddad, 1995).
Those studies bring enough evidence that the household should not be seen as a single economic
actor, as there are individual preferences and distinct bargaining power between men and women
(Doss, 2005). The creation of income opportunities for women, as in the arapaima co-
management, may result in various benefits to the household and to the community as a whole in
the long-term.
The participation of women in arapaima fisheries was favored by some features of the
co-management scheme. Firstly, arapaima fisheries moved the focus from a few men experts
to a collective activity, where knowledge is to be shared and replicated. Also, it created labor
division, generating multiple job opportunities for distinct members of the community. Labor
division resulted in the need for capacity building, and women consequently had the
opportunity of learning different skills related to arapaima fisheries, which favored their
inclusion in the co-management. Nevertheless, although women participation is currently
happening in many arapaima co-management initiatives across the Amazon, it is still
geographically limited considering the initiatives as a whole (IBAMA, personal
communication). Since each community has autonomy to decide some specificities of their
co-management arrangement, the inclusion of women is not a default outcome and depends
on the spontaneous initiative of the community. Such initiative likely depends on contextual
features, such as women historical empowerment in place, previous communal experiences
and their relationship with gender issues, external influences etc. Studies focusing on this
55
aspect, surveying a wide range of arapaima co-management initiatives throughout the
Amazon, would be desirable to help us better understand why in some of the schemes women
were included whereas in others not.
Despite the lack of information in such large scale, pointing out the factors that may
explain the spontaneous inclusion and recognition of women in the arapaima co-management,
the experience promoted by the initiatives addressed in this paper could serve as a model to
other co-management schemes, not only of arapaima but to any fisheries scheme throughout
the world. The mechanisms that favored women inclusion in our study area (capacitated labor
division with financial recognition) could be adapted to different contexts seeking to promote
the opportunity of women inclusion in activities that they may be interested in, but are not
used to participate due to cultural constraints.
Importantly, women inclusion should not be limited to the harvest/post-harvest
sectors. Women need to be included in the decision making process, and to feel at ease to
expose their demands and opinions (Di Ciommo and Schiavetti, 2012; Harper et al., 2013;
Koralagama et al., 2017). Studies worldwide suggest that women tend to have low
participation in fisheries meetings and fishing decision-making forums (Di Ciommo and
Schiavetti, 2012; Eder, 2005; Harper et al., 2017; Kleiber et al., 2018; Smith, 2012). The
reasons are many and vary from case to case – e.g. not being invited to the meetings; not
feeling truly welcome; feeling uncomfortable and inhibited in male-dominated spaces; feeling
their opinions are not valued; not having her contribution in fisheries recognized; not having
someone to leave the children with; and the widespread bias of women being seen primarily
as mothers and wives while men as breadwinners and leaders (Alonso-Población and Siar,
2018; Di Ciommo and Schiavetti, 2012). In the arapaima co-management, such global pattern
of low female effective participation in the decision-making seems to be reproduced. Even in
the communities where women have got financial recognition for the participation in
arapaima fisheries, they often do not express their opinions nor participate actively in the
fishery decision making (CTF personal observation). Because women role in fisheries has
been historically undermined, they may need stimuli to empower themselves, while both men
and women may need stimuli to realize the importance of having both genders’ workforce
being equitably represented and recognized (Bennett, 2005; Di Ciommo and Schiavetti 2012).
Despite the increasing attention being given to the gender dimension in the
development agendas, and the growing number of studies highlighting the relevance of
female workforce and recognition in fisheries (e.g. Bennett 2005; Di Ciommo and Schiavetti
2012; Harper et al. 2015; Koralagama et al. 2017; Salmi and Sonck-Rautio 2018; Zhao et al.
56
2013), much more needs to be done in practical terms. Women continue to be a hidden
workforce worldwide and to be marginalized from decision-making. This status quo is
reflected on, and fed back by, fisheries’ research, management and policies, which tend to
acknowledge and focus on the male workforce only (Bennett, 2005; Kleiber et al., 2015;
Salmi and Sonck-Rautio, 2018). To reach the global Sustainable Development Goal of gender
equity (United Nations, 2015) in the fisheries domain, it is necessary to ensure opportunities
for women recognition and their effective inclusion, which implies valuing their workforce
and promoting their participation, including in the decision-making (Harper et al., 2013). That
could be stimulated in several different ways. On the one hand, empowerment, emotional
support and opportunities for reflection could be promoted through institutional support,
social groups, courses, forums, and others strategies and policies addressing gender equity
(Bennett, 2005; Zhao et al., 2013). For example, in the Tanga region of Tanzania, an IUCN
project helped increase female involvement and decision-making in fisheries by raising
awareness and support among women and men for a more equitable representation, and by
developing women confidence to participate in meetings (Tobey and Torell, 2006). In
Uganda, women empowerment has increased after an institutional policy change that sought
to integrate the marginalized groups in decision-making by ensuring their representation in
the fisheries committees (Nunan, 2006). On the other hand, policies related to the supply
chain could stimulate women formal inclusion through financial stimulus to the producers, as
for instance by creating certification labels that add value to products promoting gender
equity in fisheries.
CONCLUSION
In the Amazon, as worldwide, women often represent a hidden workforce in fisheries,
contributing to the activity but not having their efforts recognized. Arapaima co-management
represents a novel opportunity for Amazonian women to be financially rewarded for their
participation in a fisheries scheme. Having income going directly to the women will likely
trigger various positives effects, such as increased autonomy and more balanced power in
relation to the men, and improved child care and family’s health. The inclusion of women in
arapaima fisheries, an activity previously restricted to the men, was made possible by some
features of the co-management arrangement, as labor division and capacity building of
community members. However, women inclusion in arapaima co-management is still limited
to a few initiatives, and much is yet needed to include women in the decision-making
processes and to reach gender equity in the fishery scheme. Despite such important
57
limitations, the initiatives addressed in this paper represent a step forward in women
recognition in fisheries, and could serve as a model to be adapted to other fisheries schemes
worldwide seeking to promote greater gender equity in fisheries.

ABSTRACT
Co-management has been advocated as an effective tool to achieve natural resource
conservation worldwide. Yet, the potential of co-management arrangements can fail to be
realized when there is insufficient local engagement. In this perspective paper, we argue that
co-management schemes focusing on culturally important species (CIS) can help overcome
this issue by engaging local people’s interest. To develop this theory, we explore published
data on the outcomes of two management schemes, both encompassing multiple independent
initiatives, to discuss CIS-management effects and benefits. We also show a compilation of
CIS examples throughout the world, and discuss the potential of CIS-management to reach a
global audience. Based on these data we argue that CIS-management can be an effective tool
to reconcile the often intractable goals of biodiversity conservation and human welfare.

1. INTRODUCTION
Collaborative management (co-management) of natural resources has become increasingly
widespread worldwide, especially after the 1980s, when local people, conservationists, and
researchers began searching for alternatives to the often unsuccessful top-down management
schemes prevalent at the time (Jentoft 1989; Pomeroy and Berkes 1997; Berkes 2009). Co-
management implies a participatory decision-making process in which the regulation of
natural resource use is shared between the users and other stakeholders, such as the national
or subnational government, NGOs and local cooperatives (Berkes et al. 2001). In cases where
local people are exerting continuous direct influences on species and their habitats, such
locally inclusive management approaches tend to be more effective and successful for natural
resource conservation than non-participatory systems (McClanahan et al. 2006; Gutiérrez et
al. 2011; Cinner et al. 2012).
Despite its widely acclaimed potential, co-management arrangements can also fail
(Jentoft et al. 1998; Béné et al. 2009; Terborgh and Peres 2017), often due to lack of local
community involvement (Jentoft 2000) or frail official institutional support (Terborgh and
Peres 2017). When official enforcement is absent or ineffective, local engagement may be the
only way to ensure an effective vigilance system to enforce compliance by outsiders (Cinner
et al. 2012). Poor enforcement is ubiquitous in developing countries, typically because of
underfunding, understaffing, or low political priorities with conservation goals (Berkes et al.
2001; Campos-Silva et al. 2015). Yet, tropical developing countries host most global
biodiversity hotspots (Myers et al. 2000), and most of the world’s rural poor, who depend
directly on natural resources for subsistence and to support local economies (Fisher and
Christopher 2007). Therefore, natural resource conservation based on local engagement is
both ecologically appealing, and critical to maintain food security and social stability in
developing countries (Adams 2004; Adenle et al. 2015).
Achieving local engagement in a co-management scheme can be challenging, as
several factors may influence local interest and commitment (see e.g. Seixas and Davy 2008;
Ruiz-Mallén et al. 2015; Mistry et al. 2016). Yet, successful cases of self-organization are
normally associated with users being strongly attached to the resources in focus, which either
support a substantial portion of local livelihoods or have a high value assigned to its
sustainability (Ostrom 2009; Measham and Lumbasi 2013). Otherwise, the costs of local
engagement may not be worth the effort (Ostrom 2009). In this paper, we argue that placing
culturally important species as the focus of management schemes is a powerful mechanism to
engage local communities with conservation initiatives.
64
Culturally important species are those highly significant for local people, with
prominent functional roles in their diet, materials, medicine, cultural identity and/or spiritual
values (Cristancho and Vining 2004; Garibaldi and Turner 2004). The concept of “cultural
keystone species” (CKS) was proposed to refer to these species as an analogy to the
ecological concept of “keystone species” (sensu Paine, 1969; Power et al., 1996). As such,
CKS corresponds to species crucial to the survival of a people’s culture, without which the
society they support would be completely different (Cristancho and Vining 2004; Garibaldi
and Turner 2004). Here we use the more comprehensive term “culturally important species”
(CIS) considering that some species may play an overriding role in people’s culture yet are
not necessarily irreplaceable and indispensable to the culture’s survival. Nevertheless, the
local extinction or decline of CIS will always be critical to local peoples, likely affecting not
only their subsistence and/or spirituality, but also the transmission of Traditional Ecological
Knowledge (TEK; Berkes, 2008), and the continuity of traditional practices related to the
species.
Considering the huge impact CIS may have on local peoples’ lives, it has been argued
that these species should be taken into account by management and conservation monitoring
approaches in order to ensure local people’s long-term access to them (Cristancho and Vining
2004; Noble et al. 2016). Furthermore, local people should have the inherent right to
participate in the decision-making in managing these species, which have played fundamental
socio-cultural roles for generations (Garibaldi 2009; Butler et al. 2012; Noble et al. 2016).
Beyond the relevant issues of social justice, studies have also highlighted the potentially
positive ecological consequences of CIS-management (Garibaldi 2009; Garibaldi e Turner
2004; Cristancho and Vining, 2004; Noble et al. 2016). These authors built their assumptions
on multiple arguments, based mainly on the following ideas: (i) if local people identify
strongly with a certain species, they will have a strong desire to preserve or restore such
species, which favours conservation success (Garibaldi and Turner 2004; Garibaldi 2009); (ii)
focusing on CIS is a way to simultaneously address ecological and cultural concerns, and
having a focal set of species may be financially and logistically more manageable (Garibaldi
and Turner 2004; Garibaldi 2009); (iii) the decline of a CIS may negatively affect local
stakeholders who are effectively caring for local natural resources, which may consequently
affect the stability of the ecosystem (Cristancho and Vining 2004); (iv) CIS are often vital
species to the ecosystem where they occur, thereby their conservation should be beneficial for
both local people and the environment (Noble et al. 2016); and (v) the population recovery of
65
CIS and their habitats will support the reclamation of the habitat for associated species
(Garibaldi 2009).
Despite expectations about the positive outcomes potentially generated by CIS-
management, studies that actually show real-world results are scarce. Moreover, the use of
quantitative data to support the beneficial outcomes of using CIS-management approaches is
highly limited. This limitation is problematic as policy-makers and managers often need
quantitative data to support their decisions, particularly those related to species’ management.
Here we attempt to fill this knowledge gap by compiling quantitative data on the ecological,
social, and economic outcomes of two co-management schemes focused on CIS, with the
support of multiple independent initiatives. The data is literature-based, derived mostly from
ecological studies. Even though both schemes are focused on CIS, these studies normally fail
to address the impact of the species’ cultural importance to the success of the initiatives.
Success is generally attributed to the engagement of local people, but the triggers promoting
such successful engagement are rarely mentioned.
By assembling arguments from CIS studies and results from the two case studies, we
discuss how focusing on CIS in management schemes is a way to motivate local people
interest and involvement. A consequence of local engagement will be positive conservation
outcomes, even in cases where institutional resource governance is severely limited, as in
most developing countries. Finally, we provide a compilation of CIS examples from around
the world to discuss the potential of CIS-management applicable across a wide range of
geographic contexts.
2. METHODS
We analyzed two prominent co-management schemes established in the freshwater
ecosystems of the Brazilian Amazon. The Amazon is responsible for Brazil being one of the
five countries that together contain more than 70% of the world’s wilderness (Watson et al.
2018). At the same time, thousands of rural communities live in the Amazon and rely directly
on natural resources for their survival. Such a scenario makes it imperative to develop
strategies seeking to reconcile biodiversity conservation with the maintenance of local
people’s culture and livelihoods. We chose two examples of currently successful CIS
management strategies, which have several independent initiatives spread over a large
geographic scale (Fig. 1). The first one refers to the arapaima (Arapaima spp.; Fig. 2)
fisheries management, and the second to the conservation of freshwater turtles (Podocnemis
spp.; Fig. 3) through the protection of fluvial sand beaches. We explore both schemes to
66
discuss their main outcomes and limitations. The data used comes from the literature and
from personal direct observations in the field by the authors along their careers.
In addition to the two case studies, we present a compilation of CIS examples from
other parts of the world in order to illustrate the wide range of species that are highly relevant
to local societies worldwide. Providing a full compilation of CIS examples from all over the
globe is beyond the scope of this paper. Instead, we present a limited list of examples based
on an online search in the Web of Science database using the search terms “cultural keystone
species” OR “culturally important species” OR “culturally significant species” OR “tabooed
species” OR “cultural taboo” (all in English). We also used snowballing techniques, by
including citations found within the search publications. Our compilation was restricted to
animal species only. The examples were gathered in a table with information on (i) the
common and scientific names of the species; (ii) its general taxonomic group; (iii) its
geographic location; (iv) the culture that has identified the species as a CIS; (v) the species’
local uses and values; and (vi) the references citing each example. The information used to fill
the table came from studies found in our search and consequently do not necessarily
correspond to all data available to each species in other possible sources.

3. CASE STUDIES
3.1 Arapaima co-management
Arapaima is one of the largest freshwater fish on Earth, and an iconic element of the Amazon
(locally known as pirarucu in Portuguese, or paiche in Spanish; Fig. 2). It used to be
considered a single species (Arapaima gigas; Castello and Stewart, 2010) but is currently
referred to as Arapaima spp. due to uncertainties regarding the distribution of multiple
congeners (Stewart 2013a,b; Castello et al. 2014; Watson et al. 2016). Arapaima spp. inhabit
lakes and water channels during the dry season and migrate laterally to flooded forests when
the water levels rise (Castello 2008). The individuals are mainly fished during the dry season,
when they are concentrated in the discrete water bodies. Arapaima plays a central role in the
livelihood and cultural identity of many Amazonian peoples since pre-Columbian times,
corresponding to an important source of animal protein (Bates 1863; Veríssimo 1895; Prestes-
Carneiro et al. 2016), local medicine (Alves and Rosa 2007), and a key element in
sociocultural practices and local cosmologies (Murrieta 1998, 2001; Aparicio 2014).

68
During the 19th and early 20th century, arapaima was the most important commercial
fishery resource in the Brazilian Amazon (Veríssimo 1895; Mérona 1993), which led to its
overfishing in many areas (Castello et al. 2014). The expansion of commercial fisheries
across the Amazon River and its major tributaries from the 1960s onwards, driven by
increased fishing technologies, further aggravated the situation of arapaima stocks, as well as
other species (McGrath et al. 1993). Facing such excessive fishing pressure and its negative
consequences, some riverine communities started grassroots movements seeking to take
control of local water bodies and implement local agreements to regulate fishing activities
(McGrath et al. 1993, 2008; De Castro 2002; De Castro and McGrath 2003). These so-called
fishing agreements, starting in the 1980s, had an important repercussion and came to be
legally accepted by the Brazilian government in the late 1990s, representing an innovative
formal instrument of collaborative fisheries management (De Castro and McGrath 2003;
McGrath et al. 2008). This process created the basis for the subsequent establishment of other
fisheries co-management models in the Amazon, such as the arapaima co-management.
Arapaima co-management started as an alternative to reconcile the recovery of
arapaima stocks with its sustainable harvest, since arapaima fisheries had been banned by
local legislation in the 1990s but illegal fishing continued in the absence of adequate
enforcement (Castello and Stewart 2010; Cavole et al. 2015). The first arapaima co-
management initiative was undertaken in the early 2000s, in the Mamirauá Sustainable
Development Reserve (Solimões River basin), and showed promising results (Castello et al.
2009). After the proven success of this experience, the scheme was accepted by the Brazilian
Environmental Agency (IBAMA) as a model to be replicated in other areas, which opened the
possibility of legal arapaima fishing under specific conditions (Amazonas Normative
Instruction Nº1, 1st June 2005). The arapaima co-management model is based on a quota
system set according to the arapaima abundance within the management areas (Castello et al.
2009). The abundance is annually estimated by local people through direct visual counts; this
is possible because arapaima is an obligate air-breather coming to surface every ~15 min,
which enables fishers to count the number of individuals in the lakes and water channels
based on TEK and following a standardized protocol (Castello 2004). IBAMA is in charge of
setting the next-year quota for each community, which is allocated as a one-off annual
harvest, normally lasting from a few days to one month. In order to award IBAMA’s approval
to start an arapaima co-management system, the community must design a management plan,
which includes the zoning of the water bodies (including no-take lakes) and the establishment
69
of a local vigilance system to preclude illegal fishing (Castello et al. 2009; Amazonas Decree
Nº 36083, 23rd July 2015).
Arapaima co-management plans have proliferated throughout the Amazon over the
last years, currently encompassing > 3000 fishing households from > 450 rural communities
(IBAMA, personal communication). Studies have highlighted the positive ecological and
socioeconomic impacts of the activity. For instance, the number of arapaima adults increased
up to 24-fold after eight years of arapaima co-management in the Japurá River basin (Castello
et al. 2009); up to 29-fold after six years of co-management in the Purus River basin (Petersen
et al. 2016); and up to 30-fold after 11 years of co-management in the Juruá River basin
(Campos-Silva and Peres 2016). In all cases, arapaima declined or remained stable at low
densities in neighbouring water bodies not included in the co-management scheme (Castello
et al. 2009; Petersen et al. 2016; Campos-Silva and Peres 2016). Models testing the effect of
several predictors (including environmental and landscape variables) on the arapaima
abundance, showed that the presence of the co-management scheme was the strongest
predictor, accounting for over 70% of the observed variation in arapaima numbers (Campos-
Silva and Peres 2016). Importantly, not only arapaima populations have had advantages from
such management - other aquatic species also benefit from increased abundance with the
protection of the water bodies, such as the high-value tambaqui fish (Colossoma
macropomum; Arantes and Freitas, 2016; Silvano et al., 2009), freshwater turtles
(Podocnemis spp.; Miorando et al., 2013), and caimans (Melanosuchus niger; Projeto Médio
Jurua, unpublished data).
Arapaima co-management also brings socioeconomic benefits to the rural
communities. All arapaima harvested are sold by local people through a simplified value
chain, which results in a significant extra income. After 10 years of arapaima management in
the Japurá River basin, the per capita income from arapaima sales increased five-fold
(Amaral 2009). In the Juruá basin, it was showed that co-managed lakes can ensure an
average annual revenue of nearly US$ 10,600 per community and US$ 1,050 per household
(Campos-Silva and Peres 2016), which corresponds to about four times the Brazilian
minimum wage. Such extra income is highly relevant for local people, who have a largely
subsistence lifestyle with limited cash-earning opportunities, often earning less than the
minimum wage per month. Furthermore, revenues from arapaima sales are received as an
annual windfall, which enables investments that local participants could not make otherwise,
including improvements in fisheries enforcement and communal assets, such as local schools,
medical care, and power generators for household and community lighting (CTF and JVCS,
70
personal observation). In addition to the economic outcomes and its indirect social benefits,
interviews with self-declared former illegal arapaima fishers showed that most of them (75%)
highlighted that arapaima co-management helps strengthen cultural values, and many (68%)
declared that local people’s pride and self-esteem increased due to the success they achieved
in restoring arapaima populations (Campos-Silva and Peres 2016). Some interviewees (28%)
also mentioned the more equitable income distribution as another important outcome, since
arapaima fisheries are now a collective enterprise rather than having the benefits fall to only a
few experienced fishermen (Campos-Silva and Peres 2016).
3.2 Freshwater turtle conservation through fluvial sand beach protection
The genus Podocnemis includes four extant species of freshwater turtles in the Brazilian
Amazon, all of them commonly used by local people: The giant South American turtle
(females locally known as tartaruga and males as capitarí; Podocnemis expansa; Fig. 3A),
the yellow-spotted river turtle (tracajá/zé prego; P. unifilis; Fig. 3B), the six-tubercled river
turtle (iaçá/pitiú; P. sextuberculata; Fig. 3C), and the red-headed river turtle (irapuca; P.
erythrocephala; Fig. 3D). These four species occur in rivers, lakes and floodplain forests, and
use fluvial beaches to nest (Smith 1979; IUCN 2018).
Podocnemis spp. play a central role in the livelihood and cultural identity of many
Amazonian peoples since pre-Columbian times (Bates 1863; Silva-Coutinho 1868; Carvajal
1894; Veríssimo 1895; Prestes-Carneiro et al. 2016). Local people value both adults and eggs
for multiple purposes, especially as food delicacy and medicinal resource, in addition to being
a highly important item in social practices and celebrations (Smith 1974; Alho 1985; Johns
1987; Rebêlo and Pezzuti 2000; Alves and Rosa 2007; Pezzuti et al. 2010; Alves et al. 2012).
Podocnemis spp. are also greatly valued by riverine peoples as a special food item to diversify
their otherwise monotonous fish-based diet (Murrieta 1998).
71

During the 18th and 19th centuries, following the European colonization, millions of
freshwater turtles were slaughtered yearly, and their eggs widely converted into oil for
cooking and urban lightning (Smith 1979). This led to a sharp decline in turtle populations. In
the 1960s, a National Law was established in Brazil banning the hunting and
commercialization of wild animals (Brazilian Fauna Protection Law, Nº 5197, 3rd January
1967), which consequently discontinued legal trade of turtles. However, high levels of illegal
harvesting continued in the absence of adequate enforcement (Fachín-Terán et al., 2004;
Kemenes and Pezzuti, 2007; Peñaloza et al., 2013). The situation was aggravated by the
construction of highways and large hydroelectric dams directly impacting the nesting beaches
(Smith 1979; Alho 2011; Norris et al. 2018a). Faced with the depletion of Podocnemis spp.
stocks, local communities started on the ground conservation initiatives, focused on
protecting turtle nesting beaches (Andrade 2007). These initiatives were eventually supported
by government institutions, NGOs and/or researchers, and proliferated throughout the
Amazon (Andrade 2007; Cantarelli et al. 2014).
72
The management scheme is based on the establishment of protected beaches whereby
local beach-guards are in charge of surveillance, and nest monitoring (IBAMA 2016). Each
protected beach is constantly surveyed, day and night, by one to three guards, to avoid
poaching of adults and eggs during all the nesting period (dry season; ~ 5 months). In some
places beach-guards work on a voluntary basis, while in others they are financially supported
by the local government and receive a monthly payment during the nesting period. The
payment is delivered either in cash (amount equivalent to the Brazilian minimum wage, ~
US$ 250/month) or, more commonly, as a food hamper (equivalent to less than half a
minimum wage; ~ US$ 110/month; Campos-Silva et al., 2018).
Studies have highlighted positive impacts of turtle management schemes. For instance,
comparisons between areas with and without the scheme, showed that in the Lower Amazon
the managed areas had ten-fold more P. sextuberculata, and accounted for 91% of the total
individuals caught in the entire study area (Miorando et al. 2013). In the Juruá basin, managed
areas had 58 times more P. expansa, six times more P. unifilis, and three times more P.
sextuberculata (Campos-Silva et al. 2018); moreover, 99% of all P. expansa nests recorded
on unprotected beaches were raided by poachers compared to only 2.1% on adjacent protected
beaches (Campos-Silva et al. 2018). Studies tested the effect of several environmental and
social variables on turtle abundance, and community-based beach protection was the strongest
one for both P. sextuberculata (Miorando et al. 2013) and P. expansa (Campos-Silva et al.
2018). Data accumulated through the Podocnemis expansa Conservation Program across nine
states of the Brazilian Amazon, showed that protected beaches produced at least 46 million
hatchlings in 30 years, and resulted in P. expansa population recovery in most areas
(Cantarelli et al. 2014). Furthermore, a study focusing on P. unifilis showed that two years of
government enforcement patrols had no effect on nest harvesting, whereas one year of co-
management in the same area resulted in almost threefold reduction of harvest levels (Norris
et al. 2018). In addition to Podocnemis spp., protected beaches benefits species from several
other groups, such as beach-nesting birds, large catfishes, terrestrial invertebrates, river
dolphins, caimans and green iguanas (Campos-Silva et al. 2018). The magnitude of
differences in the abundance varies across species, with some being overwhelmingly more
abundant on protected beaches (e.g. 83-fold for black skimmers, Rynchops niger; Campos-
Silva et al., 2018).
In contrast to the arapaima co-management, the turtle management scheme does not
represent a cash-earning opportunity for the community and cannot become financially self-
sufficient over time, due to the legal impediment to the harvest and trade of turtles and their
73
eggs in Brazil (Brazilian Fauna Protection Law, Nº 5197, 3rd January 1967; Brazilian
Environmental Crimes Law, Nº 9605, 12th February 1998). The economic benefits, if any, are
restricted to the beach-guard’s nominal symbolic payment only, and come from external
input. Such absence of tangible financial return is frequently mentioned by beach-guards as
one of the main concerns for the long-term sustainability of the activity (Campos-Silva et al.
2018). They also complain about the lack of appreciation of their role by government
authorities and the wider society, who fail to adequately recognize the considerable time and
effort they invest in the conservation scheme, and the personal risks they incur from
confronting recalcitrant poachers (Campos-Silva et al. 2018). Another often expressed
concern is the insufficient support from government agencies, both in terms of financial
assistance (e.g. investment on basic equipment or on fuel for patrols) and official enforcement
(e.g. application of formal sanctions to identified poachers) (Campos-Silva et al. 2018;
Pezzuti et al. 2018; CTF and JVCS personal observation). On the other hand, beach-guards
often highlight the strengthening of local cultural values as a great positive outcome from the
turtle conservation scheme (Campos-Silva et al. 2018). Furthermore, communities where
protected beaches emerge are seen as privileged areas, and residents feel proud of the
increasingly abundant turtle population (Pezzuti et al. 2018).
4. CIS THROUGHOUT THE WORLD
The two case studies explored above are examples of currently active CIS-management
schemes, for which we have quantitative data demonstrating the outcomes. We used those
examples to better illustrate how CIS-management systems may be successful in both
ecological and social terms. Other examples might be found in other parts of the world, and
many more could exist if there were adequate initiatives to motivate their establishment.
Indeed, in our compilation of CIS examples worldwide (Table 1), we showcase a wide range
of CIS, encompassing several taxonomic groups and environments, as well as different uses
and values for various peoples throughout the world. This compilation, which may represent
only a small portion of all existing examples, illustrates the potential of CIS management to
span a wide geographic scale. Each culture has its own CIS, and often these have a strong
effect on the ecosystem they inhabit, which make them especially relevant for management
and conservation purposes (Close et al. 2002; Noble et al. 2016).

5. DISCUSSION
The two case studies addressed in this paper show important similarities and differences
(Table 2) that have direct implications to their ecological, social, and economic
outcomes. Even though the initiatives focusing on Arapaima spp. and Podocnemis spp.
are naturally restricted to the Amazon, they both bring relevant insights to wildlife
management and conservation, applicable to multiple contexts throughout the world.
Hereafter, we discuss some of the key learnings from the two case studies and propose a
general framework regarding CIS-management schemes.

a Community involvement on turtle co-management (beach protection) varies across different locations. In many
cases, however, only one to three beach-guards are in charge of the management rather than the whole
community.
b Trade of wild arapaima is allowed only under co-management schemes approved by the Brazilian
Environmental Agency (IBAMA), who is in charge of setting annual quotas to each management unit according
to the local arapaima abundance.
c In some locations beach guards receive a monthly payment during the turtle nesting period. This payment may
be delivered either in cash or as a food hamper, and needs to come from external sources (e.g. local government
or NGOs). The activity itself does not generate income. Illustrations: Karla Koehler

5.1 Key learnings from the case studies
5.1.1 Learnings from similarities between the case studies
In both Arapaima spp. and Podocnemis spp. managements it is clear that the strong
connection local people have with the target species resulted in a deep cultural incentive
to seek the recovery of their populations to sustainable levels. Such local interest
stimulated communal engagement with conservation initiatives focusing on these
species. The local engagement, in turn, triggered the success of the initiatives and was
so effective that it has become the strongest predictor of species abundance across
multiple contexts (Miorando et al. 2013; Campos-Silva and Peres 2016; Campos-Silva
et al. 2018). Indeed, if local people are thoroughly engaged, there is better potential for
full-time physical presence and effective local surveillance, as they are permanent
residents in the target areas (Jentoft et al. 1998; Pomeroy et al. 2001; Ostrom 2007).
Moreover, people from the same or neighbouring communities normally know each
other well and can easily distinguish non-compliant individuals. Even though kinship
ties may represent a barrier for local sanctions (Crawford et al. 2004), peer pressure and
moral obligation are often stronger determinants of people’s behaviour than formal
rules, especially in places where official surveillance is low or non-existent (Kaplan
1998; Sutinen and Kuperan 1999; Crawford et al. 2004).
The two case studies are also actual examples of how top-down enforcement, as
currently deployed, is not necessarily effective across the Brazilian Amazon. Despite
the legal restrictions to the harvest of Arapaima spp. and Podocnemis spp.,
independently imposed decades ago, both species still face overfishing/overhunting
scenarios in many areas due to high levels of illegal harvest throughout the region
(Castello et al. 2009; Miorando et al. 2013b; Campos-Silva and Peres 2016; Petersen et
al. 2016; Campos-Silva et al. 2018; Norris et al. 2018b). Indeed, about 77% of all
arapaima landed in Santarém (a major Amazonian city) was estimated to be illegal,
which corresponds to the highest rate of illegal fishing ever reported in the global
literature, and to more than four times the world average (Cavole et al. 2015). Another
study showed that in only two years, ~4000 Podocnemis spp. individuals illegally
harvested were confiscated by park wardens in a single Reserve, an amount that
probably represents only a small fraction of all turtles poached in that specific area
(Kemenes and Pezzuti 2007). The overall depletion scenario of Arapaima spp. and
84
Podocnemis spp. contrasts with the impressive recovery these species are demonstrating
in areas where local people are engaged in co-management initiatives focusing on them
(Castello et al. 2009; Miorando et al. 2013; Cantarelli et al. 2014; Campos-Silva and
Peres 2016; Petersen et al. 2016; Campos-Silva et al. 2018; Norris et al. 2018b).
Another important aspect present in both case studies is that the corresponding
management schemes do not focus on benefiting the target species only (Table 2).
Instead, they are both based on rules and procedures that embraces the ecosystem scale
and consequently benefit many co-occurring non-target taxa. The arapaima co-
management is grounded on the zoning of the water bodies, including no-take lakes,
while the turtle co-management scheme is centered on the protection of the entire
fluvial beach. Therefore, these management initiatives could be considered examples of
Ecosystem-Based Management (EBM; Pikitch, 2004). Similar management schemes,
focusing on CIS but based on rules aimed to protect the entire ecosystem, would be
strongly advised to other contexts as well. The focus on CIS may be a trigger to spark
local people’s motivation and real engagement in EBM schemes.
The spatial planning of the management scheme may be another relevant feature
for its broader success. As illustrated by our case studies, the ecological benefits can be
enhanced by the establishment of a zoning based on a source-sink model, in which the
species could recover in no-take areas and spill-over to other areas (Stobart et al. 2009;
Di Lorenzo et al. 2016; Campos-Silva et al. 2017). It is also important to design
monitoring strategies aiming at verifying population trends over time. Quantitative
studies are especially advantageous in this case, as they enable following up on the
changes in an objective way, comparable at both temporal and spatial scales, and may
also be useful to avoid misinterpretations of the stocks condition due to the “shifting
baseline syndrome” (sensu Pauly, 1995). Yet, community-based monitoring should be
prioritized, as local people are an essential part of the scheme, and ought to be
empowered and recognized as protagonists, and duly rewarded for their efforts.
5.1.2 Learnings from differences between the case studies
Income generation viability may be a relevant factor to ensure the long-term
sustainability of the conservation initiative (Pomeroy et al. 2001). Some people may be
interested in a certain initiative due to cultural or moral motivation only and be willing
to sacrifice income or incur personal costs to carry out a moral duty (Sutinen and
85
Kuperan 1999), as is the case of many beach-guards involved in the turtle management
scheme. Beach protection is a high-risk activity with frequent threats of violence from
poachers (including death threats) and the material benefits, if any, are negligible
considering the high workload the activity demands and the risks involved (Campos-
Silva et al. 2018; Pezzuti et al. 2018). Turtle management scheme is mainly motivated
by community ethics, and emotional connection with Podocnemis spp. (Pezzuti et al.
2018). It is an actual example that nonmaterial motivations should not be seen as side-
effects of cultural processes, but rather as conscious decisions based on local values
(Pezzuti et al. 2018). Nevertheless, motivations can change over time. As anticipated by
many beach-guards, social and market pressures might have a negative effect on beach-
guards’ long-term engagement or on their replacement by future generations (Campos-
Silva et al. 2018). If a beach-guard gives up or has no successor, all the conservation
gains made over the years can be quickly lost. In contrast, in the arapaima co-
management, sales of sustainably harvested fish bring direct economic benefits for
many families in the community, which entails compliance and long-term engagement
among the entire fishing village, and encourages community-led surveillance and
widespread peer pressure. Finding ways of generating income from the beach protection
may enhance communal involvement and long-term commitment with the scheme, and
reduce poaching. Furthermore, transforming the beach protection in a self-sustaining
scheme, as is the arapaima co-management, would make it less vulnerable to
oscillations in political interests and external support, which would likely increase the
probability of its long-term success (Campos-Silva et al. 2018).
Yet, such striking financial contrast between the two cases is consequence of an
important intrinsic difference between them: while national legislation prevent turtle
harvesting in Brazil, specific legal norms allow regulated arapaima trade (e.g.
Amazonas Normative Instruction Nº 01, 1st June 2005; Acre Normative Instruction Nº
01, 30th May 2008; Rondônia Normative Instruction Nº 02, 13th May 2019). Turtles and
fish exhibit different life-histories that have direct implications to their management and
may impose more challenges to the sustainable use of the former. Delayed sexual
maturity and long reproductive life span, for example, are features associated with the
vulnerability of turtles to the exploitation of juveniles and adults (Thorbjarnarson et al.
2000). However, a recent study focusing on P. unifilis showed that increasing first-year
survival could generate rapid population increases and even compensate for population
86
losses due to adult harvesting (if adult female harvest remains < 25%). P. unifilis is a
relatively fast maturing species, with maturation age similar to arapaima, which
contrasts with the slower maturing temperate and larger-bodied marine turtles (Norris et
al. 2019). Furthermore, studies have shown that the sustainable harvest of turtle eggs
can represent a viable management alternative (Alho 1985; Campbell 1998; Escalona
and Fa 1998; Pezzuti and Vogt 1999; Caputo et al. 2005), especially in places where a
high proportion of nests is normally lost for natural causes, as in many Amazonian
fluvial beaches (Pezzuti and Vogt 1999; Caputo et al. 2005). Despite successful
examples elsewhere of sustainable harvest/trade of turtle eggs (e.g. Costa Rica -
Campbell 1998; Ecuador - Caputo et al. 2005), the attempt to test a similar program in
Brazil is limited by national legislation banning the use of wildlife other than fisheries
(Brazilian Fauna Protection Law, Nº 5197, 3rd January 1967; Brazilian Environmental
Crimes Law, Nº 9605, 12th February 1998). Yet, scholars have advocated that legal
arrangements enabling regulated turtle harvest may be the most effective way to ensure
the long-term conservation of Podocnemis spp. in the Amazon, considering the scenario
of deficient enforcement associated with high levels of widespread illegal harvest (Alho
1985; Pezzuti and Vogt 1999; Campos-Silva et al. 2017, 2018; Pezzuti et al. 2019).
The role of education and outreach is another important contrasting aspect that
emerges from a comparison between the two case studies (Table 2). Arapaima co-
management has been acclaimed by the media, the government and NGOs, and there is
a widely built perception that the scheme is fruitful for the community and relevant for
conservation. Conversely, beach protection is a neglected initiative with little public
profile throughout the region, despite its long history and great importance (Pezzuti et
al. 2018). Formal recognition may be an effective support and stimulus to local
engagement and peer pressure, since it is a way to trigger the wide collective perception
that the scheme is beneficial, and therefore morally and ethically defensible (Crawford
et al. 2004). The severe lack of societal appreciation of the turtle management scheme,
together with the poor financial viability of the initiative, might lead to its future failure,
as anticipated by many beach-guards (Campos-Silva et al. 2018).
5.2 CIS-management and its potential applicability to multiple contexts worldwide
Despite particular bottlenecks, both case studies can be considered successful examples
of CIS-management. The role of CIS to motivate local engagement with the initiatives
87
ensured continued on-the-ground enforcement of conservation practices, which was
essential for the successful recovery of target and non-target species, and subsequent
profound sociocultural benefits. Similar outcomes could likely be achieved with many
other CIS, as those listed on Table 1. Yet, when designing a CIS-management proposal
it is indispensable to analyze the singularities of each reality. The cultural importance of
a species is always context-dependent, and a certain species that is highly important to
one group may not be to another, even if both groups are in contact with the same
species (Garibaldi and Turner 2004). The relevance and uses of a species may also
change over time, as cultures are dynamic and adaptive (Cristancho and Vining 2004).
Furthermore, each ecosystem will function in a particular way (and also change over
time), and rules or strategies operating in one place may not be suitable to another, even
if the target species are the same. Developping CIS-management proposals in close
partnership with local people is therefore crucial to ensure that the proposed scheme is
culturally, socially and ecologically relevant and approriate, in addition to being flexible
to changes. However, it is important to evaluate the impact that the target CIS may have
on the natural ecosystem functioning, avoiding efforts to support eventual non-native
species that become a CIS (Nuñez and Simberloff 2005).
The general steps and feed processes expected to be found in any CIS-
management initiative are outlined as a flow chart in Fig. 4. The process illustrated in
this figure may be briefly described as following: an ecosystem-based co-management
scheme with a focus on CIS will likely arouse local people interest on the initiative,
stimulating their engagement. Such engagement will likely result in local compliance
and surveillance, and consequently bring dividends to ecosystem conservation and
species recovery. Species recovery will likely generate direct and indirect ecological,
cultural, social, and economic benefits, which may reinforce local people interest in the
initiative, resulting in further reinforcing feedback to the system (Fig. 4).
As such, management schemes focusing on CIS could trigger positive socio-
ecological consequences at multiple scales in many different contexts throughout the
world. The positive impact of CIS-management may be especially meaningful in the
context of developing countries, where not only official enforcement tends to be weak
or non-existent (Berkes et al. 2001; Campos-Silva et al. 2015), but also corruption tends
to be high (Transparency International 2018). The common mismanagement of public
finances and/or bribery of officials frequently happening in these countries further
88
aggravates difficulties in implementing effective enforcement schemes (Smith et al.
2003; Agnew et al. 2009). As such, triggering local people interest and consequent
engagement on conservation initiatives may often be the best solution for ensuring the
perpetuation of local natural resources.
Figure 4. Flow chart representing steps and feed processes expected to be found in any conservation initiative focusing on Culturally Important Species (CIS). Continuous lines indicate processes very likely to happen, while dashed lines indicate processes that may happen depending on the context. In general, the flow chart shows that (1) ecosystem-based co-management schemes focusing on a CIS will likely arouse local people interest on the initiative; (2) once they are interested, they will be keen to get engaged on it, which will likely result in (3) local compliance and surveillance, and consequently bring dividends to (4) ecosystem conservation and species recovery. Species recovery will likely (5) bring direct and indirect ecological, cultural, social, and economic benefits, which will (6) reinforce their interest in the initiative, resulting in further reinforcing feedback to the system.
6. CONCLUSION
The cultural importance of any given species should be regarded as a highly relevant
aspect in conservation strategies designed for areas where natural resource use is critical
to local livelihoods. Given that local people have the most to gain from CIS population
recovery, management initiatives focusing on those species have a strong potential to
stimulate local people interests, and their consequent engagement, compliance and
enforcement. Such local, full-time surveillance is potentially much more effective than
official mechanisms of institutional enforcement, which are typically deficient and
deployed sporadically, especially in countries with low governance levels. Importantly,
89
the proposed focus on CIS does not mean that the management initiatives should be
designed to benefit the target species only. We advocate management schemes with
rules embracing the ecosystem scale and ensuring that many other species, and the
environment as a whole, will also benefit from the conservation initiative. The focus on
CIS may be seen as an effective trigger to spark local people’s motivation and real
engagement in the conservation scheme. As such, the scheme will likely achieve a wide
range of positive ecological, social, cultural and economic outcomes. Therefore, we
claim that CIS-management can be an effective socio-ecological tool to reconcile
biodiversity conservation with local people quality of life, keeping with the Sustainable
Development Goals set out by the United Nations to guide developing policies (United
Nations 2015).

CONCLUSÃO GERAL
Nesta tese, foram abordados distintos aspectos do comanejo do pirarucu, um sistema
socioecológico existente na Amazônia Brasileira. No primeiro capítulo, aspectos
ecológicos foram tratados sob uma perspectiva histórica, a partir do uso de entrevistas
para acessar as percepções de pescadores sobre mudanças na abundância e tamanho do
pirarucu ao longo do tempo. Nós mostramos que as populações de pirarucu vinham
sofrendo um drástico declínio desde meados do século XX, mas vêm aumentando em
diversas áreas nos últimos anos. Esse aumento, no entanto, não acontece em todos os
lugares, sendo bastante associado à existência do comanejo do pirarucu na região. O
método utilizado neste capítulo se mostrou muito útil para acessar dados populacionais
de espécies proibidas, especialmente nos casos em que a exploração ilegal continua
acontecendo. Foram sugeridas estratégias específicas para adaptar este método a outros
contextos do mundo. No segundo capítulo, concluímos que o manejo do pirarucu vem
promovendo um maior reconhecimento financeiro da participação das mulheres em
atividades pesqueiras. Tal reconhecimento pode gerar diversas consequências positivas,
como um aumento da autonomia e empoderamento feminino, do cuidado com as
crianças e da saúde da família. Esse exemplo do manejo do pirarucu poderia servir
como um modelo a ser adaptado para outras realidades, com vistas a promover uma
maior equidade de gênero nas mesmas. Nós abordamos algumas características do
manejo que provavelmente favoreceram essa inclusão e reconhecimento da mulher, e
discutimos algumas limitações atuais dessa inclusão, tanto em termos geográficos
quando da participação da mulher em processos de tomada de decisão. No terceiro
capítulo, foi sugerida que a importância cultural de uma espécie deveria ser encarada
como um aspecto relevante em estratégias de conservação voltadas para áreas onde o
uso de recursos naturais é crucial para a subsistência dos povos locais. Considerando
que esses povos têm interesse direto em ver a recuperação das espécies com as quais
estão diretamente conectados, estratégias de manejo que foquem nessas espécies têm
maior potencial de estimular o interesse dos povos locais e seu consequente
engajamento na iniciativa. Nós sugerimos que a iniciativa de manejo abarque regras que
favoreçam o ecossistema como um todo, e que o foco em uma espécie culturalmente
importante (CIS) funcione como um gatilho para despertar a motivação e envolvimento
dos usuários na iniciativa. Assim, diversos benefícios ecológicos, sociais, culturais e
