一、材料与方法1.对罗非鱼成鱼池套养密度的拟定通过对罗非鱼成鱼池自繁罗非鱼幼鱼产量进行了测产,结果发现,自繁幼鱼平均亩产达106千克。根据自然界营养级之间的能量转移效率“百分之十规律”,设想套养鳜鱼、加州鲈鱼苗出池规格达到150克,套养成活率在50%～70%之间,则每亩应套 I. Materials and Methods 1. Tilapia fish pond nursery stocking density of tilapia into fish ponds since the production of tilapia juvenile fish production was measured and found that the average per mu of juvenile fish up to 106 kilogram. According to the nature of the energy transfer between the trophic level of “ten percent rule”, envisaged nursery rinses, California bass seedlings out of the pool size reached 150 grams, nursery survival rate of 50% to 70%, then the acre Should be set
