为了探讨噬菌蛭弧菌（Bdellovibrio bacteriovorus）在池塘养殖生产中的效果,向大宗淡水鱼类混养池泼洒噬菌蛭弧菌,观察养殖池养殖水体的水温、pH值、NH3-N、亚硝酸盐、硫化氢等主要水质指标的变化及鱼的死亡情况。结果表明：蛭弧菌制剂对养殖水体的主要水化指标具有明显的改善作用,试验塘的NH3-N、亚硝酸盐值极显著低于对照塘（p〈0.01）,而试验塘与对照塘的硫化氢、pH值差异不显著（P〉0.05）。在鱼病预防方面,蛭弧菌制剂使用后,能有效预防草鱼的赤皮、烂鳃和肠炎病,草鱼的发病率、死亡率明显下降。

The experiment aimed to study the effect of BdeUovibrio bacteriovorus on water quality of pond cuhure.Bdellovibrio bacteriovorus was poured into the four major Chinese carps and carp and auratus mixed cultivation pond,and the changes of the water quality parameter such as water temperature ,pH value, H2S content ,NH3-N and NO2-N content ,and the death numbers of fish were studied.It was demonstrated that the main water quality indexes of the ponds could be remarkably improved by the use of Bdellovibrio bacteriovorus.It also helped to accelerate the reduction of the content of NH3-N and NO2-N in the aquaculture water.The NH3-N and NO2-N content in the experimenta groups were dramatically lower than those in the control groups (P〈0.01), but the changes of H2S and pH value were not obvious (p〉0.05).On the aspects of preventing against fish disease,the use of Bdellovibrio bacteriovorus helped to effectively prevent the red skin disease,gill disease and enteritis of grass carp.The incidence and mortality rate of grass carp were also reduced.
