鸡粪的再利用,已在许多国家取得显著效果。近年来,我国把鸡粪应用到养猪上越来越多,但直接把鸡粪用于养鱼,目前尚为数不多。据有关资料报道,一只产蛋母鸡的产粪量一年足够生产4～7公斤鱼,一只后备鸡可生产3～4公斤鱼,一只肉鸡可产2～3公斤鱼。四川省荣昌县远觉乡养鸡专业户黄聘菊,用鸡粪养鱼已初步获得成功。该专业户现养有产蛋鸡420只,并承包了一个5亩面积的水塘养鱼。1983年上半年新入的鱼苗,年底收获鲜鱼1700多斤。1984年约生产成鱼3000公斤以上,亩产600公斤。即每只产蛋鸡生产7.15公斤鱼。

In recent years, more and more pigs have been applied to raising pigs in our country, but there are still a few chicken dung used directly for fish farming. According to relevant information, the production of one hen can produce enough 4 to 7 kilograms of fish per year, one can produce 3 to 4 kilograms of fish, and one broiler can produce 2 to 3 kilograms of fish.
