CHANGES OF FATTY ACID COMPOSITION IN CARP DURING WINTER

This paper reports the changes of fatty acid composition of silver carp,bighead carp,mirror carp and hybrid carp cultured in cages in Chao Yang reservoir of Jilin Province during winter.The fatty acids composition of total lipids of muscle in four kinds of fishes was not affected owing to starvation. But the content of saturated fatty acids and the ratio of saturated to unsaturated fatty acids reduced in low temperature. The monoethylenic acids increased and docosahexenoic acid (DHA)decreased significantly in hybrid carp. The changes may affect over-winter capability of carp.
