主体尼罗罗非鱼养殖池套养加州鲈对比试验

A contrastive experiment that main T.nilotica L. is bred with Microperus salmoides in the same fishpond

尼罗罗非鱼生长迅速 ,繁殖力强 ,在主体尼罗罗非鱼养殖池塘中 ,套养一定数量的加州鲈 ,可以吃掉达不到上市规格的尼罗罗非鱼苗种 .试验结果表明 :主体尼罗罗非鱼养殖池塘中套养加州鲈 ,在不增加饵料成本的前提下 ,每亩可增加加州鲈 2 8 7公斤 。

Sunmary T nilotica L grows and breeds quickly In the same fishpond if main T nilotica L is bred with some amount of Microperus salmoides,it can eat up T nilotica L fry,which can not be put on a market The experiment indicates that Microperus salmoides can increase by 28 7k g per mu and the econmic benefit is apparently improved on the premise that the cost of bait isn't increased ,if it is
