各鸡场常有大小不一的鱼塘,一般利用鸡粪喂养4大家鱼,虽然头两年可获得较好的效果,但随着年限增加其产鱼量锐减甚至绝产。而在池塘中喂养胡子鲶则获得显著的经济效益。 笔者在自己的小型鸡场内挖有约1.2亩水面的鱼池,1987年开始以鸡粪为主要饲料喂养常规家鱼,当年获得亩产600公斤的好收成。随后逐年下降,直至1990年投放鱼 The farms often have different sizes of fish ponds, the general use of chicken manure feeding 4 big fish, although the first two years to get better results, but with the increase of the number of fish production sharply or even cut. The feeding of bearded catfish in ponds has significant economic benefits. I dug in its own small farm about 1.2 acres of fish pond surface, starting in 1987 with chicken manure as the main feed to feed conventional fish, then get a good yield of 600 kg per mu. It then declined year by year until the fish was launched in 1990
