Abstract The proximate composition ,amino acid profiles and fatty acid compositions were comparativey analyed in muscle of three Yellow River carp Cyprinus carpio populations collected from Shaanxi Xinmin Chinese carp stock farm(SX) ,Zhengzhou Yellow River carp thoroughbred farm(ZZ) ,Huayuankou section of Yiluo River (YL)and Jian carp (JL) collected from Dandong Yingbo Yalu River ecological technology Co .Ltd .The results showed that there were no significant differences in moisture and ash between the various groups ( P> 0 .05 ) . In addition to crude fat of ZZ , the Yellow River carp populations had significantly lower muscular compositions than C .carpio var .jian farmed population(JL) did and ,crude protein of SX was significantly higher than the other three carp populations(P<0 .05) .The maximal total amino acids ,essential amino acids and total amino acids were observed in SX ;contents of essential amino acids in descending order was SX>YL>JL>ZZ .Essential amino acid index (EAAI) of JL was the highest with the average of 90 .11 .Content of monounsaturated fatty acids was the highest in ZZ ;content of polyunsaturated crude fatty acids of JL was the highest ,rather than the maximal total amount of saturated acids was observed in SX ,meanwhile the highest value of essential fatty acids was found in YL .According to nutrition evaluation in amino acids score(AAS)and chemical score(CS) ,the first limited amino acid was valine AAS in four common carp populations ,second limiting amino acids were isoleucine(Ile);CS second limiting amino acids were methionine + cysteine(Met + Cys) .
