摘要

A two-month trial was carried out in China to evaluate the possibility of recycling animal manure through pond tilapia production.And the effects of chicken manure,cattle manure and chicken-cattle mixture together on the water quality and tilapia production were investigated.The results showed that the yield of tilapia was 3.46,3.89,2.49 and 3.20 kg in the control,chicken M,cattle M,and chicken-cattle M,respectively,and the tilapia yields following the order of chicken M>control>chicken-cattle M>cattle M.The tilapia yield in chicken M group increased by 12.43% compared with the control.Chicken manure could increase the tilapia production,but cattle manure has no the effect.And the effect of animal manure on water quality showed that adding chicken manure into tilapia pond could make water quality decreased at the beginning 20 d,but could increase water quality after 20 d and stabilize the phytoplankton structure.
