In 1940, Alaska pollock was the most commonly caught fish in Korea, with more than 270,000 tonnes brought in from the Sea of Japan. [3] However, the consumption of Alaska pollock in South Korea dropped to an estimated 260,000 tonnes per year by 2016, [ 4 ] Much of is imported from Russia due to changes in sea water temperatures.
Alaska pollock catches from U.S. fisheries have been relatively consistent at approximately 1.3 million tons a year, on average 92 percent from the Bering Sea and 8 percent from the Gulf of Alaska. [ 35 ] [ 36 ] Each year's quota is adjusted based on stock assessments conducted by the Alaska Fisheries Science Center to prevent overfishing. [ 37 ]
Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).

To illustrate the amounts of EPA and DHA in supplements, a softgel capsule containing fish oil derived from pollock might contain a total of 642 mg of total fish oil, of which 584 mg are omega−3 fatty acids, with 377 mg EPA and 158 mg DHA. 3 That same company's salmon oil softgel contains 1008 mg of total fish oil, of which 295 mg are omega ...
The roe of marine animals, such as the roe of lumpsucker, hake, mullet, salmon, Atlantic bonito, mackerel, squid, and cuttlefish are especially rich sources of omega-3 fatty acids, [1] but omega-3s are present in all fish roe. Also, a significant amount of vitamin B 12 is among the nutrients present in fish roes.

[9] [10] Eating about 140 grams (4.9 oz) of oily fish rich in omega-3 fatty acids once per week is a recommended consumption amount. [9] [10] Increasing intake of omega-3 fatty acids may slightly reduce the risk of a fatal heart attack, [10] but likely has little effect on the overall number of deaths from cardiovascular disease.
