Aquaculture Divisions, E-Institute of Shanghai Universities, Shanghai , China) Abstract: A 12-week growth trial was conducted with juvenile gibel carp (Carassius auratus gibelio) to evaluate their ability by utilize different dietary lipids. Ten diets were supplemented with 8% of either fish oil (FO), coconut oil (CNO), corn oil (CO), linseed oil (LO), soybean oil (SO), rapeseed oil (RO), 1 1 fish oil-coconut oil (FCNO), 1 1 fish oil-corn oil (FCO), 1 1 fish oil-linseed oil (FLO) or fish-coconut-corn-linseed oil mixture (MIX). Each diet was fed to triplicate groups of fish (initial weight: 3.53 g, 30 ini.) in a recirculation system at (24±1).Weight gain were the highest in SO and CNO group, followed RO and the lowest in FO, CO and LO group, when used as a single lipid source. Compared to total replacement of fish oil, coconut oil, corn oil or linseed oil substitute 50% fish oil led to a higher weight gain, respectively. Neither the plasma biochemistry nor the lipid and moisture contents in different tissues of gibel carp showed significant difference between groups (P>0.05). Fatty acid composition of muscle in fish generally reflected the composition of the diet. Fish fed CO and SO had higher 20:4n-6, while relative higher 20:5n-3 and 22:6n-3 was detected in fish fed LO. These results suggested that gibel carp had ability to desaturate and elongate 18:2n-6 and 18:3n-3 to highly unsaturated fatty acid. In conclusion, soybean oil, coconut oil and rapeseed oil were good alternative lipid sources for gibel carp. Key words: Gibel carp; Lipid sources; Growth; Muscle fatty acid composition
