Abstract
We studied the composition and content of fatty acids (FA) in the muscle, liver and reproductive tissues of males and females of perch from the Krasnoyarsk reservoir at the late stages of the reproductive cycle. The dynamics of the FA composition of perch muscle tissue was determined by a seasonal change in food sources composition, whereas the FA composition of the liver and gonad was influenced by the reproductive cycle and had differences between males and females. Multivariant analysis showed a redistribution of the FA between gonads and liver tissue. The nutritive value of perch muscle tissue, as a source of long-chain polyunsaturated fatty acids, did not depend on the reproductive stage.
