摘　　要：通过静态单因子急性毒性试验,表明硫酸铜对泥鳅水花和夏花苗种的24,48,96 h的半致死浓度(LC50)分别为0.702,0.587,0.509 mg/L和1.810,1.412,1.270 mg/L,安全浓度分别为0.05,0.13 mg/L;硫酸亚铁对泥鳅水花和夏花苗种的24,48,96 h的半致死浓度(LC50)分别为12.472,9.819,8.297 mg/L和24.876,19.024,16.833 mg/L,安全浓度分别为0.83,1.68 mg/L;戊二醛对泥鳅水花和夏花苗种的24,48,96 h的半致死浓度(LC50)分别为13.286,13.264,12.319 mg/L和45.101,42.701,40.547 mg/L,安全浓度分别为1.23,4.05 mg/L;氧化钙对泥鳅水花和夏花苗种的24,48,96 h的半致死浓度(LC50)分别为102.609,102.299,98.815 mg/L和119.345,117.288,114.305 mg/L,安全浓度分别为9.88,11.43 mg/L。在泥鳅苗种阶段,药物敏感性由大到小依次为硫酸铜、硫酸亚铁、戊二醛、氧化钙。The single factor experiment of static acute toxicity tests showed that the LC50 in 24 hours,48 hours and 96 hours of copper sulfate for loach fingerlings and fry were respectively 0.702,0.587,0.509mg/L and 1.810,1.412,1.270mg/L,the safety concentrations were 0.05mg/L and 0.13mg/L;the LC50 in 24 hours,48 hours and 96 hours of ferrous sulfate for loach fingerlings and fry were respectively 12.472,9.819,8.297mg/L and 24.876,19.024,16.833mg/L,the safety concentrations were 0.83mg/L and 1.68mg/L.the LC50 in 24 hours,48 hours and 96 hours of glutaraldehyde for loach fingerlings and fry were respectively 13.286,13.264,12.319mg/L and 45.101,42.701,40.547mg/L,the safety concentrations were 1.23 mg/L and 4.05 mg/L.the LC50 in 24 hours、48 hours and 96 hours of calcium oxide for loach fingerlings and fry were respectively 102.609,102.299,98.815mg/L and 119.345,117.288,114.305mg/L,the safety concentrations were 9.88mg/L and 11.43mg/L.In the stage of loach fry,the degrees of drug sensitivity were in the order as follows： copper sulfate ferrous sulfate glutaraldehyde calcium oxide.
