辽宁彰武县水产技术推广站李树青等,将鸡粪发酵后均匀泼洒鱼池,以施肥代替投喂豆浆或其他精料,取得明显的经济效果和技术效果.本项试验从1991年开始.已连续三年.第一年平均每亩年产鱼种200公斤.第二年263.5公斤,第三年329公斤.三年的鱼种规格平均分别为13厘米、16厘米、20厘米.用鸡粪培育鱼种.每培育1公斤鱼种只需0.3元的鸡粪,仅相当于投喂豆浆的1/10.据有关材料介绍,鸡仅能消化吸收饲料中营养成份的27%,其大部分被排泄于体外,可供鱼类直接利用.同时,体长不足10厘米的鲢、鳙、青、鲤等鱼苗,其食性以浮游动物为主.鸡粪肥水,可培育大量浮游生物,为鱼苗提供食饵.利用鸡粪培育鱼种,取材为便、技术易于掌握,成本低.效果好,具有推广价值.
Liaoning Zhangwu County Fisheries Technology Promotion Station Li Shuqing and so on, the chicken manure evenly sprinkle sprinkling fish ponds to fertilize instead of feeding soy milk or other concentrate, and achieved significant economic and technical effects .This test began in 1991. Has been continuous In the first year, the average annual yield per mu is 200 kilograms of fish species, 263.5 kilograms for the second year and 329 kilos for the third year, with average three-year species sizes of 13 centimeters, 16 centimeters and 20 centimeters, respectively. Fish species per 1 kg of fish species only 0.3 yuan of chicken manure, only the equivalent of feeding soy milk 1 / 10. According to the relevant materials, chickens can only digest and absorb nutrients in feed 27%, most of them Excreted in vitro, for direct use of fish.At the same time, body length of less than 10 cm of silver carp, bighead carp, blue carp and other fry, their feeding habits to zooplankton mainly chicken manure water, can cultivate a large number of plankton for the fry provide Prey.Using chicken manure to cultivate fish species, drawn for the convenience, technology is easy to grasp, low cost. Good effect, with promotional value.
