摘  要：
采用静水实验方法和改良寇式法计算,以鲈鱼Lateolabrax japonicas、矛尾虾虎鱼Chaeturighthys stigmatia Richardson为实验材料开展了鱼藤酮的急性毒性实验。结果表明:鱼藤酮分别处理6h、9h、18h、21h、24h时鲈鱼的半致死浓度(LC_(50))分别为18.40μg/L、17.83μg/L、14.55μg/L、14.32μg/L、13.72μg/L,鲈鱼半致死浓度的95%置信区间分别为17.29~19.58μg/L、17.22~18.46μg/L、13.92~15.10μg/L、13.69~14.97μg/L、13.18~14.27μg/L;鱼藤酮分别处理24h、48h、72h时矛尾虾虎鱼的半致死浓度(LC_(50))分别为45.35μg/L、26.59μg/L、16.96μg/L,矛尾虾虎鱼半致死浓度的95%置信区间分别为42.01~48.85μg/L、24.78~28.54μg/L和16.09~17.88μg/L。2种鱼类的半致死浓度都非常低,而矛尾虾虎鱼对鱼藤酮的耐受性更强一些,鱼药毒性等级划分显示鱼藤酮对两种鱼类均属于剧毒性物质。

摘  要：
The acute toxicity of rotenone to Lateolabrax japonicas and Chaeturichthys stigmatias was determined with the hydrostatic test method.The semi lethal concentration(LC_(50))of L.japonicas for6 h,9 h,18 h,21 h,and 24 hrotenone treatments was 18.40μg/L,17.83μg/L,14.55μg/L,14.32μg/L and 13.72μg/L respectively,with the corresponding 95% confidence interval of 17.29~19.58μg/L,17.22~18.46μg/L,13.92~15.10μg/L,13.69~14.97μg/L,and 13.18~14.27μg/L.However,when C.stigmatias was treated with rotenone,the semi lethal concentration(LC_(50))and its95% confidence interval were 45.35μg/L and 16.09~17.88μg/L,26.59μg/L and 42.01~48.85μg/L,16.96μg/L and 24.78~28.54μg/L as were observed after 24,48 and 72h.These results showed that the semi lethal concentration of these two fishes to rotenone was very low,but C.stigmatias had a higher tolerance to rotenone than L.japonicas.The toxicity grade showed that the rotenone belonged to the highly toxic substances to these two fishes.
