Abstract: Abstract: At water temperature 26.0 to 27.5 degrees and hydrostatic conditions in the room，the acute toxicity of CuSO4, High chloride, Albendazole, BCDMH, Trichlorfon and Hundred of Cyrtomium fortunei powder were conducted by Cyprinus carpio larvae which average body length and average weight were 7.5-9.1cm and 7.3-9.2g. The results showed that the safety concentration of CuSO4, High chloride, Albendazole, BCDMH, Trichlorfon, Hundred of Cyrtomium fortunei powder were 0.17mg/L, 3.86g/m3, 7.35mg/L, 11.70mg/L, 18.05g/m3, 70.80g/m3 respectively, the sensitivity in order of six kinds drugs were CuSO4 > High chloride > Albendazole > BCDMH > Trichlorfon > Hundred of Cyrtomium fortunei powder. The safety concentration of High chloride, BCDMH, Trichlorfon and Hundred of Cyrtomium fortunei powder were significantly higher than the production using dosage, so they can be used safely in cultivation of Cyprinus carpio. the safety concentration of CuSO4 were significantly lower than the production dosage, on Cyprinus carpio production using, this paper proposes to reduce the dosage. The bath dose range of Albendazole had not been reported on fishers yet, so the test results could be used as reference in future.
