摘要：A two-month trial was carried out to evaluate the possibility of using algae and animal manure in tilapia culture.And the effect of algae,chicken manure and algae mixture together,cattle manure and algae mixture together,chicken-cattle manure and algae mixture together on the water quality and tilapia production was researched.The results showed that the yield of tilapia were 3.46,4.33,3.81,2.92 and 3.76 kg in Control,Algae,Chicken-A,Cattle-A and C-C-A,respectively,following the order of Algae>Chicken-A>C-C-A>Control>Cattle-A,and tilapia yield in Algae and chicken manure treatment groups increased by 25.0%and 10.1%respectively compared with the control.Algae and chicken manure could increase the tilapia production,but cattle manure has no the effect.And the effect of algae and 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 it can stabilize the phytoplankton structure in aquaculture water.Adding Chlorella vulgaris and Scenedesmus quadricauda into tilapia pond could make water quality in a good state during the aquaculture process and it can stabilize the phytoplankton structure in aquaculture water.
