摘　　要：采用静水式急性毒性试验法研究了吡喹酮、甲苯咪唑和溴氰菊酯对花鳗鲡(Anguilla marmorata)(体重为0.87±0.19 g)的急性毒性。试验结果表明,在水温28±2℃时,吡喹酮对花鳗鲡的24 h LC50、48 h LC50、72 h LC50、96 h LC50分别为73.85 mg/L、66.71 mg/L、56.57 mg/L、52.72 mg/L,安全浓度为16.34 mg/L;甲苯咪唑对花鳗鲡的24 h LC50、48 h LC50、72 h LC50、96 h LC50分别为142.81mg/L、13.80 mg/L、5.19mg/L、1.74mg/L,安全浓度为0.023 mg/L;溴氰菊酯对花鳗鲡的24 h LC50、48 h LC50、72 h LC50、96 h LC50分别为9.56μg/L、9.34μg/L、7.69μg/L、7.67μg/L,安全浓度为2.68μg/L。吡喹酮、甲苯咪唑、溴氰菊酯对花鳗鲡分别属于低毒、中毒、剧毒药物。甲苯咪唑对花鳗鲡的安全浓度0.023 mg/L远低于欧洲鳗鲡(Anguilla anguilla)的常用浓度1～2 mg/L,因此在花鳗鲡养殖中使用甲苯咪唑制剂需十分谨慎。The acute toxicity of Praziquantel,Mebendazole and Deltamethrin on marbled eel Anguilla marmorata（Weight 0.87±0.19 g）was studied under laboratory conditions（water temperature 28±2℃）.The mean static acute 24 h LC50 of Praziquantel,Mebendazole and Deltamethrin on marbled eel were 73.85 mg/L,142.81 mg/L,9.56 μg/L respectively;the 48 h LC50 were 66.71 mg/L,13.80 mg/L,9.34 μg/L,respectively;the 72 h LC50 were 56.57 mg/L,5.19 mg/L,7.69 μg/L,respectively;the 96 h LC50 were 52.72 mg/L,1.74 mg/L,7.67 μg/L respectively;the safe concentration（SC） were 16.34 mg/L,0.023 mg/L,2.68 μg/L,respectively.Results indicated that Praziquantel,Mebendazole and Deltamethrin on marbled eel belonged to the low-toxic substance,the middle-toxic substance and the high-toxic substance.
