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.
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]
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 ...
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).

This fish was claimed as a 'World record' at 130lb 10oz, [13] although the weighing process used is in doubt. In addition to being caught for sport , mahseer are also part of commercial fishing and ornamental or aquarium fish.
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]
Fish meal is made from both whole fish and the bones and offal from processed fish. It is a brown powder or cake obtained by rendering pressing the whole fish or fish trimmings to remove the fish oil. It used as a high-protein supplement in aquaculture feed. Fish sauce is a condiment that is derived from fish that have been allowed to ferment ...
