【摘要】 将建鲤夏花放在池塘内进行集约化养成,经人工驯养并投喂全价颗粒配合饲料,178天后尾均重由0.9g增长到570g,增重倍数633.3,成活率79.6%,单产1140kg/1000 m~2,蛋白利用率为27.5%,饲料系数1.46,投入与产出比为1:2.42。更多还原

【Abstract】 Jian carp summerlings, artificially domesticated and fed with complete pellets, were intensively reared in pond. The average body weight was increased from 0.9 g to 570g,633.3 times of increasing after 178 days’ of rearing. The survival rate was 79.6% and the average yield reached 1140 kg/1000 m~2. The net protein utilization rate of the diet was 27.5% and the food coefficient was 1.46. The ratio between input and output was 1:2.42.更多还原
