草鱼联合疫苗是由荧光假单胞菌、肠型点状产气单胞菌、鱼害粘球三种菌联合配制成的三联苗。采用常温静水实验法[1],用此疫苗对草鱼水花进行毒性检验。结果表明:联合疫苗对草鱼水花的24h、48h、96h的半致死浓度分别为1375g/m3、354g/m3、109.375g/m3,安全浓度为109.375g/m3。 Grass carp vaccine is a combination of the three strains of Pseudomonas fluorescens, Enterobacteriaceae aeromonas, fish sticky ball triple formulated vaccine. Using normal temperature hydrostatic test method [1], the vaccine for grass carp aquatic toxicity test. The results showed that the combined lethal concentrations of the combined vaccine against grass carp were 1375g / m3, 354g / m3 and 109.375g / m3, respectively, at a safe concentration of 109.375g / m3 at 24h, 48h and 96h.
