It is used industrially in the production of docosahexaenoic acid. [2] Crypthecodinium cohnii is a heterotrophic non-photosynthetic Microalgae . C. cohnii can acclimate a higher docosahexaenoic acid to polyunsaturated fatty acids ratio, [ 3 ] however current studies are trying to increase the volume of DHA production by creating mutant strains.

Sablefish flesh is high in long-chain omega-3 fatty acids, EPA, and DHA. It contains about as much as wild salmon. [22] Smoked sablefish, often called simply "sable", has long been a staple of New York appetizing stores, one of many smoked fish products usually eaten with bagels for breakfast in American Jewish cuisine.

DHA in breast milk is important for the developing infant. [10] Rates of DHA production in women are 15% higher than in men. [11] DHA is a major fatty acid in brain phospholipids and the retina. Preliminary research has investigated its potential benefit in Alzheimer's disease, [1] [12] and cardiovascular disease, [13] and other disorders. [1]
[2] [3] The three types of omega−3 fatty acids involved in human physiology are α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). ALA can be found in plants, while DHA and EPA are found in algae and fish. Marine algae and phytoplankton are primary sources of omega−3 fatty acids. [4]
DHA has 6 cis (see Cis–trans isomerism) double bonds each one of which is located between carbons 4-5, 7-8, 10-11, 13-14, 16-17, or 19-20. Cytochrome P450 epoxygenases attack any one of these double bonds to form a respective docosapentaenoic acid (DPA) epoxide regioisomer .
Studies have shown that commercial fish supplemented with DHA during the spawning season tend to grow faster and have greater survival rates with reduced abnormalities. [ 159 ] [ 160 ] Astaxanthin , a keto-carotenoid, derived from thraustochytrids have also been used to feed fish, chicken, and turkey, and to even dye food.
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 ...
