摘要
采用生物毒性试验方法进行了阿维菌素和甲苯咪唑对黄河鲤的急性毒性试验。结果显示:阿维菌素对黄河鲤的24、48和96 h半致死浓度分别为8.72,7.85,6.97×10-3 mg/L;安全浓度为1.91×10-3 mg/L。甲苯咪唑对黄河鲤的24,48和96 h半致死浓度分别为4.29,3.98,3.53 mg/L;安全浓度为1.23 mg/L。结果表明这两种杀虫药物的安全浓度都接近甚至低于它们在养殖生产中的的使用浓度,所以在养殖生产中应该谨慎使用。
To obtain the semi-lethal concentrations and the safe concentration of abamectin and mebendazole to Cyprinus carpio,acute toxicity experiments to C.carpio were performed using biological toxic test method.The results showed:the semi-lethal concentration of abamectin to C.carpio at 24,48 and 96 h was 8.72,7.85 and 6.97×10-3 mg/L,respectively,and the safe concentration of it was 1.91×10-3 mg/L;the semi-lethal concentrations of mebendazole to C.carpio at 24,48 and 96 h was 4.29,3.98 and 3.53 mg/L,respectively,and the safe concentration of it was 1.23 mg/L.The safe concentration of the two kinds of disinfectant were close to,or even lower than their dousing concentration in aquaculture.Therefore,abamectin and mebendazole must be used cautiously in the aquaculture production of C.carpio.
