全年鱼饲料用量应根据计划年底出塘鱼的产量来确定,即全年需要的鱼饲料量等于池塘内计划鱼产量×饲料的搭配比例×饲料系数(饲料系数是每生产1公斤鱼所需要的饲料总量。实践证明,每增重1公斤草鱼,需陆草40公斤或水草80～100公斤;每增重1公斤鲢、鳙鱼,需鲜牛粪40～50公斤或人畜粪50公斤或化肥1.24公斤)。例如用投饵方法主养草鱼,全年预计每公顷水面总产量为3750公斤,其中草
The amount of fish feed used throughout the year should be determined according to the output of the pond at the end of the plan year. That is, the amount of fish feed required for the whole year is equal to the planned fish output in the pond × The proportion of feed × The feed factor (Feed factor is required for producing 1 kg of fish Of the total amount of feed.It has been proved that for each weight of 1 kg of grass carp, we need 40 kg of weeds or 80 to 100 kg of weeds. For each kilogram of silver carp and bighead carp, we need 40-50 kg of fresh cow dung or 50 kg of human and animal manure Or 1.24 kg of fertilizer). For example, grass carp is mainly used for feeding. The total output of water surface per hectare is estimated to be 3,750 kg for the whole year, of which grass
