Impact of selective fishing?
Trophic levels: the number of steps, in a food web, that separates organisms from the primary producers at the base of that food web. Trophic levels (TL) tend to range in marine food webs between 1 (phytoplankton, other algae, detritus) and 5 (killer whales, polar bears), and usually are non-integers (e.g., 2.2 for krill; 3.6 for a mackerel; 4.1 for a tuna, etc.), because most consumers have an eclectic diet (see also FishBase ECOLOGY Table ).

Ecosystem Approach to Fisheries Management (EAFM)
What is the ecosystem approach to fisheries management (EAFM)?
In 2003, the United Nations Food and Agriculture Organization (FAO) defined EAFM as An approach to fisheries man- agement and development that strives to balance diverse societal objectives, by taking into account the knowledge and uncertainties about biotic, abiotic, and human components of ecosystems and their interactions and applying an integrated approach to fisheries within ecologically meaningful boundaries
