摘　　要：采用静态急性毒性试验法,开展了硫酸铜、敌百虫、甲苯咪唑、聚维酮碘等4种水产常用药物,对华鳈鱼苗的急性毒性试验。结果表明,硫酸铜对华鳈24,48和96 h的半致死浓度(LC_(50))分别为0.63,0.41和0.29 mg/L,安全浓度(SC)为0.05 mg/L;敌百虫对华鳈鱼苗24,48和96 h的LC_(50)分别为58.73,25.58和13.98 mg/L,SC为1.44 mg/L;甲苯咪唑对华鳈鱼苗24,48和96 h的LC_(50)分别为4.89,3.11和2.57 mg/L,SC为0.38 mg/L;聚维酮碘对华鳈24,48和96 h的LC_(50)分别为11.58,10.43和10.31 mg/L,SC为2.54 mg/L。指出,硫酸铜慎用于试验规格的华鳈鱼苗,敌百虫、甲苯咪唑、聚维酮碘可用于试验规格华鳈鱼苗的疾病防治。In order to investigate the acute toxicity and safe dosage of four commonly used aquatic drugs,copper sulfate,trichlorfon,mebendazole,and povidone-iodine on Sarcocheilichthys sinensis,and we tested their acute toxicity effects on Sarcocheilichthys sinensis under hydrostatic conditions.The results show that the LC_(50)(24,48 and 96 h)of copper sulfate were 0.63,0.41 and 0.29 mg/L,respectively,and the safety concentration was 0.05 mg/L.The LC_(50)(24,48 and 96 h)of trichlorfon were 58.73,25.58 and 13.98 mg/L,respectively,and the safety concentration was 1.44 mg/L.The LC_(50)(24,48 and 96 h)of mebendazole were 4.89,3.11 and 2.57 mg/L,respectively,and the safety concentration was 0.38 mg/L.The LC_(50)(24,48 and 96 h)of povidone-iodine were 11.58,10.43 and 10.31 mg/L,respectively,and the safety concentration was 2.54 mg/L.In conclusion,copper sulfate should be used with caution in the research specification of Sarcocheilichthys sinensis,while trichlorfon,methylimidazole,and povidone-iodine can be used for disease prevention and treatment of Sarcocheilichthys sinensis fry in this specification.
