Abstract:
Fatty acid status of the White Sea herring from Dvina, Kandalaksha and Onega Bays of the White Sea in autumn was investigated. The fatty acid profile of the herring groups from studied sites was characterized by high amount of monounsaturated fatty acids, among which 18:1(n-9) and 16:1(n-7) dominated. The herring from Kandalaksha Bay had higher (р≤0.05) level of 18:1(n-9) fatty acid than the fish from Onega Bay, whereas the last one was characterized by low (р≤0.05) level of 16:1(n-7). Polyunsaturated fatty acids (PUFA) were the second largest group in the herrings, mainly because of (n-3) fatty acids. In the herring from Onega Bay, the level of 22:6(n-3) was significantly (p≤0.05) higher than in other fishes. Besides that, this fishes were characterized by high level of (n-3)/(n-6) PUFA, 18:3(n-3)/18:3(n-6) and 16:0/18:1(n-9) ratios. Detected lipid status reflects ecological and biochemical features of fish adaptation in relation to specific ecological factors of the inhabitation areas of the White Sea and choice of optimal and adequate survival strategy in sub-Arctic. The results of this work present information about some features of mechanisms of adaptations on the level of lipid spectra and the role of fatty acid constituents in ecological and biochemical adaptions of the White Sea herring.
