摘　　要：为了给河南黄河鲤鱼的种质资源保护以及肉质的改良提供科学依据,试验以人工养殖的河南黄河鲤鱼和野生黄河鲤鱼为研究对象,分为野生组、养殖组,测定这两组鱼的肌纤维直径和密度以及肌肉常规营养成分、机体必需微量矿物质元素钙和磷的含量以及氨基酸组成。结果表明:野生组黄河鲤鱼的水分含量显著高于养殖组(P<0.05),粗脂肪以及粗蛋白质含量显著低于养殖组(P<0.05);养殖组黄河鲤鱼7种必需氨基酸总量和氨基酸总量均略高于野生组(P>0.05);野生组黄河鲤鱼的磷含量略高于养殖组(P>0.05),钙含量低于养殖组(P>0.05)。肌纤维特征分析表明,两个群体黄河鲤鱼的肌纤维直径平均值差异显著(P<0.05),肌纤维密度差异极显著(P<0.01)。The aim of the current study was to protect the Henan Yellow River carp germplasm resources and provide the scientific basis for the improvement of meat quality, the artificial breeding of the Henan Yellow River carp and wild Yellow River carp were chosen as the research tar- get. In our study, the carp muscle fiber diameter and density, as well as calcium and phosphorus content, amino acids, and the routine nutri- tive components, were detected, respectively. The results showed that the moisture content of the wild carp was significantly higher than that of farmed （ P 〈 0.05 ） ; the crude fat and protein were both significantly lower than that of farmed Henan Yellow River carp （ P 〈 0.05 ） ; the total essential amino acids and the sum of amino acids of farmed carp were slightly higher than that of the wild carp group, but no significant differ- ence was observed between the two groups （ P 〉 0, 05 ） ; calcium and phosphorus content of the wild group were higher than that of farmed group （ P 〉 0.05 ）. The analysis of the muscle fiber characteristics revealed that muscle fiber diameter in Henan Yellow River carp meant exhibted no significant difference （P 〈 0.05 ） between the two groups, and the muscle fiber density had extremely significant difference （P 〈 0.01 ）.
