摘　　要：为了比较豫选黄河鲤(Yuxuan Cyprinus carpio haematoperus)与豫选黄河鲤2号(Yuxuan Cyprinus carpio haematoperusⅡ)幼鱼生长性状、肌肉营养成分及抗氧化性能,试验选择体质健壮、规格整齐、初始体重为(138.92±9.13)g、体长为(17.52±1.31)cm的豫选黄河鲤和豫选黄河鲤2号各600尾,将每个品种鱼分别随机放入3个网箱中,每个网箱中各200尾,养殖时间为117 d,试验开始时测定试验初体重,试验结束后观察体色,测定成活率、生长性能指标(试验初体重、试验末体重、增重率、试验末体长、肥满度、饲料系数和体重变异系数)、肌肉营养成分(水分、蛋白质、脂肪和粗灰分)含量、抗氧化性能指标[超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、过氧化氢酶(CAT)活性和丙二醛(MDA)含量]、溶菌酶(LZM)及鳃丝Na^(+)/K^(+)-ATP酶活性。结果表明:豫选黄河鲤与豫选黄河鲤2号均具有野生黄河鲤的形态特征。与豫选黄河鲤比较,豫选黄河鲤2号的试验末体重、增重率和肥满度均显著提高(P<0.05),饲料系数显著降低(P<0.05),成活率和体长均差异不显著(P>0.05)。豫选黄河鲤和豫选黄河鲤2号的体重变异系数分别为3.17%和1.65%,肌肉蛋白质含量分别为17.51%和17.78%,脂肪含量分别为3.41%和3.21%。与豫选黄河鲤比较,豫选黄河鲤2号肌肉中蛋白质含量显著提高(P<0.05),水分、脂肪和粗灰分含量均略有降低但差异不显著(P>0.05);血清SOD和GSH-Px活性均显著提高(P<0.05),而肝脏、肾脏、脾脏SOD和GSH-Px活性均差异不显著(P>0.05);各组织的CAT和LZM活性均差异不显著(P>0.05),肝脏的MDA含量显著降低(P<0.05),肾脏和脾脏MDA含量均差异不显著(P>0.05);鳃丝Na^(+)/K^(+)-ATP酶活性显著提高(P<0.05)。说明豫选黄河鲤2号比豫选黄河鲤生长速度更快,规格更整齐,肌肉蛋白质含量更高,抗氧化性能更优良,具有较广的选育和发展前景。In order to compare the growth traits, muscle nutritional composition and antioxidant properties between the juveniles of Yuxuan Cyprinus carpio haematoperus and Yuxuan Cyprinus carpio haematoperusⅡ, the experiment selected Yuxuan Cyprinus carpio haematoperus and Yuxuan Cyprinus carpio haematoperusⅡ, each with 600 tails, which were robust and neat in size, with an initial weight of(138.92±9.13) g and a body length of(17.52±1.31) cm. Each type of fish was randomly placed into 3 cages for breeding, with 200 fish in each cage, and the breeding time was 117 d. At the beginning of the experiment, the initial body weight was determined.At the end of the experiment, the body color was observed, the survival rate was determined, and the following indexes were determined, which include the survival rate and growth performance indexes(the initial body weight of the test, the body weight at the end of the test, the weight gain rate, the body length at the end of the test, the fatness, the feed coefficient and the coefficient of variation of body weight), contents of muscle nutritional composition(moisture, protein, fat and crude ash), antioxidant performance indexes(antioxidant enzyme activities such as superoxide dismutase [SOD], glutathione peroxidase [GSH-Px],catalase [CAT], and malondialdehyde [MDA] content), lysozyme(LZM) and gill filament Na^(+)/K^(+)-ATPase activity. The results showed that both Yuxuan Cyprinus carpio haematoperus and Yuxuan Cyprinus carpio haematoperusⅡ had the morphological characteristics of wild Cyprinus carpio haematopterus. Compared with Yuxuan Cyprinus carpio haematoperus, the body weight, the weight gain rate and fatness of Yuxuan Cyprinus carpio haematoperusⅡ were significantly increased(P<0.05) at the end of the test;feed ratio was significantly decreased(P<0.05), and there were no significant differences in survival rate and body length(P>0.05). The coefficients of variation of body weight of Yuxuan Cyprinus carpio haematoperus and Yuxuan Cyprinus carpio haematoperusⅡ were 3.17
