一、饲料系数的概念 饲料系数是在养殖过程中所投料总重量与池鱼总增重量的比例。 计算饲料系数应注意主养尾数与收获尾数的差异，差异太大说明养殖过程中发生病害或搭配品种不合理，会影响到饲料系数，一般来说成鱼养殖正常成活率应在９０％左右，鱼种成活率应在８０％左右。
First, the concept of feed conversion Feed factor is the proportion of the total weight of the feed and the total weight gain of fish ponds in the breeding process. Calculate the feed coefficient should pay attention to the difference between the main mantissa and the mantissa, the difference is too large that the disease occurred in the breeding process or unreasonable with varieties, will affect the feed factor, in general, adult fish farming normal survival rate should be about 90% Fish survival rate should be about 80%.
