We have studied the composition and content of fatty acids (FAs) in the muscle, liver, and reproductive tissues of male and female of Eurasian perch from the Krasnoyarsk water reservoir at the late stages of reproductive cycle. The dynamics of FA composition of the muscle tissue correlates with seasonal changes in food-source composition, while the FA composition of the liver and gonad is influenced by the reproductive cycle and differs between males and females. Multivariate analysis shows that the redistribution of FAs at different stages of the reproductive cycle involves mainly the gonads and liver tissue. The nutritive value of the muscle tissue of perch, as a source of long-chain polyunsaturated FAs, does not depend on the reproductive stage.
