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.
It normally occurs between 0 and 20 m (0–66 ft) in depth, although both eggs and fry can be encountered as deep as 68 m (223 ft). The adult fish stay close to the bottom in daytime and rise up towards the surface at night. The juvenile fish move away from the shore where they spend their larval stage in shallow water.

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 fish oil is effectively a by-product of this process that proves to be a rich source of energy and fatty acids for fish, including the important long-chain omega-3 fatty acids EPA and DHA now linked to the health benefits associated with eating oily fish such as salmon and mackerel. Fish in general also are good sources of many vitamins and ...
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 .
Thraustochytrids have the potential to overturn exploitation of fish stocks as a new form of sustainable commercial oil producers, while also minimizing losses caused by toxic environmental exposures. [27] This can be accomplished by depriving cells from nitrogen, therefore, triggering the production of DHA. [43]
World capture fisheries and aquaculture production by species group [1] This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.
