Fatty Acids of Three Spined Stickleback (Gasterosteus aculeatus) from the White Sea
The composition of fatty acids of total lipids in muscles, liver and gonads of adults of three spined sticklebacks from the White Sea was studied. It was found that, particularly in gonads and muscles, a high level of polyunsaturated fatty acids, mainly ω-3 families, among which essential eicosapentaenoic and docosahexaenoic acids, as well as docosapentaenoic acid, dominated. The relationship between the composition of fatty acids profile in organs of stickleback and other fish species and the effect of complex environmental factors was discussed. It was shown that fatty acids were tissue-specific and their composition showed the physiological state of the organism also. The obtained results can be used both in the development of methodology in formula of food ingredients on the lipid basis from marine organisms of the Arctic region, which are an important renewable natural resource, and when studying the physiological and biochemical state of fish in the process of their development in normal and under changing environmental factors.
