| Abstract: | Objective] The research aimed to provide scientific basis for adjusting and improving the balance of aquaculture micro-ecosystem and the reasonable application of drugs.Method] Using nitrifying bacteria isolated from aquaculture water as test materials,the effects of common bactericides ClO2,KMnO4,formaldehyde,the mixture of copper sulfate and ferrous sulfate by the ratio of 5∶2 on the growth of nitrifying bacteria under the laboratory conditions were studied by the ecotoxicology method.Result] 0.1 mg/L ClO2,0.6 mg/L KMnO4,20 mg/L formaldehyde,0.7 mg/L mixture of copper sulfate and ferrous sulfate by the ratio of 5∶2 had small effects on the growth of nitrifying bacteria and better control effects on aquatic pathogenic microorganism in water body.Conclusion] In the aquiculture,suitable concentration of bactericides should be used to disinfect the water body. |
