摘　　要：为鲈鲤鱼苗病害防治的安全用药提供理论依据,采用静水试验方法,研究4种常用水产药物对鲈鲤鱼苗的急性毒性效应。结果表明:氯化钠、二氧化氯、高锰酸钾和敌百虫对鲈鲤鱼苗96h的半致死浓度分别为11 664.85mg/L、128.67mg/L、2.42mg/L和257.34mg/L,安全浓度分别为3 428.29mg/L、40.16mg/L、0.72mg/L和80.77mg/L,对鲈鲤鱼苗的急性毒性由大到小依次为高锰酸钾、二氧化氯、敌百虫和氯化钠。在鲈鲤鱼苗疾病防治中,氯化钠和二氧化氯可安全使用,敌百虫需慎用,高锰酸钾不适宜使用。The acute toxicity of four common aquatic drugs to young Percocypris pingi was determined by a still water experiment to provide the theoretical basis for safe medication in disease control of P.pingi.Result:The half lethal concentration of Sodium chloride,Chlorine dioxide,Potassium permanganate and Dipterex to young P.pingi after 96 h is 11 664.85 mg/L,128.67 mg/L,2.42 mg/L and 257.34 mg/L respectively.The safe concentration of Sodium chloride,Chlorine dioxide,Potassium permanganate and Dipterex to young P.pingi is 3 428.29 mg/L,40.16 mg/L,0.72 mg/L and 80.77 mg/L separately.The acute toxicity of four aquatic drugs to young P.pingi is Potassium permanganate>Chlorine dioxide>Dipterex>Sodium chloride.Sodium chloride and Chlorine dioxide can be used but Dipterex should be used with caution in disease control of P.pingi.Potassium permanganate can not be used in disease control of P.pingi.
