摘要
采用营天然雌核发育的普安银鲫A型为母本,建鲤为父本繁育子一代,投放1.86 g/尾的鱼种,经89 d饲养。结果:出池规格达24.1 g/尾,日增重0.25 g/尾,比普通鲫提高了0.063 g;群体增重倍数9.96倍,较对照池提高4.46倍;成活率84.5%,比对照组提高13.5百分点。子一代在生长速度和抗病性方面较对照池具有明显的优势。
F1 of Allogynogenetic Carassius auratus with 1.86g/head which crossed from maternal A gynogenetic Carassius auratus and paternal Cyprinus carpio var. jian were raised for 89 days. Results showed that average weight of fish was 24. 1 g/head with weight gain 24. 1 g/head, 0. 063g higher than common crucian. Population weight gain was 9.96 times, which higher than 4.46 times compared with control pond. Survival rate was 84.5 %, which higher than control 13.5 %. F1 showed obvious predominance on growth rate and disease resistance.
