为给黄河鲤肉质改良研究提供科学依据，分别采集了陕西新民家鱼原种场、河南郑州黄河鲤鱼良种场养殖黄河鲤和伊洛河花园口段野生黄河鲤，并与养殖范围较广的建鲤品种（采自辽宁丹东英波鸭绿江生态科技股份有限公司）作了比较分析。应用生化分析方法对4个鲤群体肌肉中的基本营养成分、氨基酸含量以及脂肪酸含量进行了分析。分析结果表明，各群体之间水分和灰分的差异不显著（P＞0．05），黄河鲤群体的粗脂肪含量除郑州良种场群体外，均显著低于建鲤群体，陕西群体的粗蛋白含量显著高于其他3个鲤群体（P＜0．05）。陕西群体的总氨基酸、总必需氨基酸和总呈味氨基酸均最高，必需氨基酸含量为陕西群体＞伊洛河群体＞建鲤群体＞郑州良种场群体。建鲤群体的必需氨基酸指数最高，平均为90．11。郑州良种场群体的单不饱和脂肪酸含量最高，建鲤群体多不饱和脂肪酸含量最高，而不饱和酸总量最大的为陕西群体，必需脂肪酸最大的为伊洛河群体。以氨基酸评分和化学评分进行评价4个鲤鱼群体的第一限制性氨基酸均为缬氨酸，氨基酸评分第二限制性氨基酸均为异亮氨酸，化学评分第二限制性氨基酸均为甲硫氨酸＋半胱氨酸。

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) .
