Conclusion

INTRODUCTIONCrab contains stomach-filling protein, which is

utilised to create and repair body tissue.

Crab is high in EPA and DHA, two anti-inflammatory

long-chain omega-3 fatty acids.

Research can help decrease blood pressure, prevent

heart disease, boost cognitive function, and treat

illnesses like psoriasis and ulcerative colitis.

Contd...

Minerals included in Crab, including copper, zinc,

and selenium, help boost the immune system.

This post examines the market analysis and

proximate composition of several crabs and the

health advantages.

INTERNATIONAL TRADEThe crab market can develop by USD 3.02

billion between 2021 and 2025, with the

market growing at a CAGR of 3.17 %.

Contd...

Crab imports (all sorts) fell from 1, 91,165 tons in the

first half of 2019 to 1, 63,055 tons in the same time in

2020. (-14.7%).

The major importer was the United States of America,

which exhibited a small decrease in imports (-1.4 %).

The Republic of Korea was the second-highest

importer, with 26,569 tons compared to 27,043 tons

during the same time in 2019.

So yet, the COVID-19 scenario does not appear to be

affecting total US crab imports.

Contd...

Imports were 59,343 tons in the first six months of 2020,

compared to 60,201 tons in the same period of 2019.

Crab shipments from Canada to the United States

increased dramatically in the first half of 2020.

A total of 14,845 tons were imported from Canada in June

alone.

Crab imports into China, on the other hand, fell by nearly

31% to 25,713 tons. All suppliers felt the decline.

The Russian Federation was the greatest provider,

although it sent 13% less than in the same time last year.

Contd...

projected to be maintained in 2020. China and the rest of Asia are anticipated to

absorb half of Russia's live crab exports.

In the first half of 2020, the Republic of Korea imported 3,339 tons of live king crab.

The Russian Federation was the most crucial provider, accounting for more than 90%

of the total.

The Republic of Korea is a chief importer of live Norwegian king crab.

The Norwegian Crab has a little higher price of USD 39.78 per kilogramme than the

Russian Crab, which fetches USD 35.27 per kilogramme (prices for June 2020).

Contd...

Although the Japanese market has slowed in recent years,

imports of frozen king crab grew to 1,202 tons in the first

half of 2020, up from 1,046 tons in the same time in 2019.

The cost of frozen king crab has also increased. Snow crab

imports from Japan, on the other hand, fell by 26% to 9,362

tons.

Russian exports fell by 13.5 % to 26,796 tons in the first

half of the year.

Republic of Kore accounting for more than two-thirds of the

total volume of the market.

Contd...

Swimming crab imports to the United States totalled 11,386 tonnes in the first six months of

2020, down just 7% from the same period last year.

Indonesia was responsible for 53% of the total, or 6,077 tonnes. Swimming crab landings

typically peak during the rainy season, which finished in July, so supplies from Indonesia are

projected to drop between the summer and the New Year.

Production isn't projected to rise again until January, when the next rainy season begins.

Thus increasing supplies won't hit the market until February 2021. It is anticipated that prices

will rise.

CRABS IN INDIA

The Portunidae family includes the majority of edible crabs found in marine and brackish

water habitats.

Podopthalmidae (Borradaile), catoptrinae (Sakai), portuninae (Rafinesque), caphyrinae

(Alcock), Carcininae (Macleay), and Polybinnae are the subfamilies of the Portunidae

family that live in the Indian Ocean (ortmann).

The protuminae subfamily is home to the majority of edible crabs found in marine and

brackishwater habitats.

Contd...

Various authors have documented the presence of five

genera of portuninae in the waters near India.

Scylla, Portunus, Charybdis, Lupocyclus, and Thalamita

are the names of the five mythical creatures. Portunus

pelagicus (blue swimmer crab), Scylla spp.

(mud crabs), P. Sanguinolentus (three-spotted Crab),

Charybdis feriatus (Crucifix crab), c.lucifera (yellowish-

brown Crab), C.Natator (line crab), and podophthalmus

vigil (line crab) are the first three genera that

contribute to the commercial crab fishery (long eye-

stalk Crab; sub fly. podopthalmidae).

All shellfish, including Crab, contain a high level of selenium.

Selenium is an antioxidant that counteracts the carcinogenic

effects of cadmium, mercury, and arsenic, all known to induce

cancers in humans.

Higher levels of selenium in the blood have been linked to a

decreased risk of cancer.

In reality, lysate, taken from the horse-shoe Crab's blue blood,

is utilised to identify spinal meningitis and combat cancer.

HEALTHBENEFITS

OF EATINGCRAB MEAT

Contd...

While crab meat has low saturated fat content, chromium in

the flesh helps raise HDL (good cholesterol) levels in the

body, lowering the risk of strokes, coronary, and circulatory

heart disease.

Crabs, in reality, contain sterol, which inhibits the

absorption of other cholesterol consumed during a meal,

therefore negating the adverse effects of other fats

consumed.

i) Cholesterol

Contd...

All shellfish, including crabs, are high in omega-3 fatty acids.

The crabs obtain these from phytoplanktons and algae, which

are an essential element of their diet.

People benefit greatly from omega-3 fatty acids because they

assist in reducing the stickiness of blood platelets, making

red blood cells more flexible and ensuring a smoother flow.

Tri-glycerides and LDL (low-density lipoproteins), which clog

arterial walls as deposits, are likewise reduced by omega-3

acids.

ii) Omega 3 fatty acids

Contd...

Crab is one of the most significant protein sources

accessible in the diet. It has about the same amount of

protein per 100 grams as meat, but none saturated fat, linked

to an increased risk of heart disease.

Because Crab lacks connective tissue, its protein is good

quality and easily digested by persons of all ages.

iii) Protein

Contd...

Selenium is abundant in all shellfish, but crab flesh is

exceptionally high in it. Selenium is an essential part of the

human antioxidant defence system, protecting cells and

tissues from damage.

Selenium is also vital for immune system function, thyroid

hormone metabolism, and reproduction hormone synthesis.

For males, 100g of crab flesh contains 112% of the required

daily intake, while it gives 140% of the daily recommended

amount for women.

iv) Selenium

Contd...

v) Riboflavin (vitamin B2)

Vitamins must be received through our diet, such as crab meat because they are water-soluble

and cannot be stored in the body.

Riboflavin (Vitamin B2) is necessary for creating steroid hormones and red blood cells and

normal development and the health of the skin, eyes, and neurological system.

Riboflavin also aids iron absorption in the gastrointestinal system and promotes antioxidant

activity. Riboflavin turnover in the human body is considered to be linked to energy expenditure.

Therefore physically active persons may have a higher need for Riboflavin in their diet.

Contd...

vi) Copper and phosphorus

The copper content in crab flesh is about 30 times

that of cod and 56 times that of salmon, chicken, and

beef.

Although iron receives the majority of the focus,

copper is involved in iron absorption, storage, and

metabolism.

It aids in creating red blood cells and maintains the

integrity of bones, blood vessels, neurons, and the

immune system.

Contd...

Phosphorus is the body's second most prevalent mineral,behind calcium.

It is a significant component of bones and teeth and plays avital role in skeletal health and development.

Phosphorus is involved in nearly every metabolic process in thebody, including kidney function, cell proliferation, and heartmuscle contraction.

It also plays a role in the conversion of food into energy.

CONCLUSION

Fishery produces 73.5 % of the crabs marketed worldwide, and there is little indication that

fisheries populations can tolerate considerable increases in catch quantities.

Climate change, overfishing, pollution, and habitat destruction, on the other hand, are likely to

drastically diminish the supply of animals in the following years or decades.

In most nations, aquaculture, on the other hand, is still a long way from being a feasible

alternative for ensuring the long-term viability of this productive chain.

Contd...

The growth of aquaculture based on caught juveniles or intermolt animals may also strain

wild populations.

Crab hatchery and rearing technology are still in their infancy, making industrial-scale

development difficult.

High production costs and accompanying hazards (such as the newly revealed highly

pathogenic reovirus) are all factors restricting aquaculture development, putting it in an

adverse position to compete with fishing.

Contd...

By conducting studies on the fisheries' biology of commercially exploited populations,

developing less predatory practises and more selective fishing gears, and reducing the

impacts associated with bycatch, fisheries companies, research institutions, funding, and

regulatory agencies are critical agencies work together.

The key issues in aquaculture include improving productivity through larviculture techniques,

focusing on reducing losses due to cannibalism, feeding larvae and juveniles, reducing viral

disease effects, and advancing the cultivation systems' technological advancement.
