The present experiment was conducted to determine the differences of nutrient composition and morphology between wild and cultured Synechogobius hasta.S.hasta were cultured in indoor flow-through fiberglass tanks and fed with iced shrimp to apparent satiation twice daily for 30 days.Wild S.hasta,coming from the same ocean zone as the cultured ones,were caught with nets.The crude protein and lipid contents,total essential amino acids(EAA) and the ratio of total EAA to total AA in whole body of wild S.hasta were significantly higher than those of cultured S.hasta(P0.05).Significant differences were also observed in condition factor(CF),viscerosomatic index(VSI) and hepatosomatic index(HSI) between wild and cultured groups(P0.05).C18:2n-6 and C18:3n-3 fatty acids contents were observed to be higher in wild S.hasta than in cultured one(P0.05).However,cultured S.hasta possessed higher C22:6n-3 fatty acid content than wild ones(P0.05),and EPA content showed no significant differences between the treatments(P0.05).
