The fatty acid composition of muscles in several wild fishes ( Coreius heterodon, Coreius guichenoti, Leptobotia elongata, Rhinogobio ventralis, Rhinogobio cylindricus) in the Yangtze River was analyzed. The results showed that saturated, monounsaturated and polyunsaturated fatty acids represent 23.90% -56.10%, 20.60% - 58.93% and 14.22% -27.25% of the total fatty acids, respectively. In the fatty acids, the saturated fatty acids (SFA) were comprised of C14:0, C16:0 and C18:0; the polyunsaturated fatty acids (PUFA) included C18:2ω6, ...
