家系黄河鲤(F_2)池塘养殖生产性能测试报告

The pond culture productivity of second generation bred line of common carp (Cyprinus carpio haematopterus)

利用4口池塘,进行了2个鲤鱼品种的养殖生产性能测试。试验鱼夏花直接养成商品鱼饵料系数在1.5和1.52,单产1871kg/667m^2和1694 kg/667 m^2;夏花培育鱼种的成活率分别是47.9%和12.3%,饵料系数是1.20和1.21,单产是822 kg/667 m^2和1429 kg/667 m^2,鱼种规格50~100 g/尾。

Four ponds were used to detect the productivity of common carp in two families. The food coefficient and yield of test fishes from fry to commercial fish were 1.5 and 1.52, 1871kg/667m2 and 1694 kg/667m2, respectively. Using young fish to produce commercial fish, the survival rates were 47.9% and 12.3%, the food coefficients were 1.20 and 1.21, the yields were 822kg/667 m2 and 1429 kg/667 m2.
