Differences in fatty acid composition between smolts of Sockeye Salmon and adults migrated from sea to lake for spawning

Abstract

According to biochemical and clinical data obtained in the last two decades, one of the main causes of occurrence and development of cardiovascular diseases is systematic deficiency in diet of essential polyunsaturated fatty acids (PUFAs) of the 3 family, such as eicosapentaenoic (20 : 53, EPA) and docosahexaenoic (22 : 63, DHA) [1]. Since EPA and DHA are efficiently synthesized only by several groups of microalgae, aquatic ecosystems are the main source of PUFAs, which are transferred along the trophic chain, for all terrestrial animals and humans.
