| 摘 要： | 采用寇氏法研究盐度、碱度对泥鳅的急性毒性作用,观察泥鳅对不同药剂的毒性反应及症状。试验结果表明,盐度对泥鳅24、48、72、96 h的半致死质量浓度分别为15.1、14.8、14.4、13.9 g/L,其安全质量浓度是4.3 g/L;碱度对泥鳅24、48、72、96 h的半致死质量浓度分别为10.3、9.0、7.9、6.6 g/L,其安全质量浓度是2.1 g/L。利用均匀设计法对盐碱的联合毒性进行了试验设计,对试验数据进行多元线性全回归分析表明:碱度的毒性作用强于盐度,盐碱联合毒性在不同时期均表现为拮抗作用。利用盐碱地和咸水进行养殖泥鳅具有较好的前景。

| Abstract: | Acute joint toxicity of salinity and alkalinity to oriential weatherfish Misgurnus anguillicaudatus was determined by Karber method.At 24,48,72 and 96 h the median lethal concentration(LC_(50)) of salinity was 15.1,14.8,14.4 and 13.9 g/L respectively,and safe concentration 4.3 g/L;24,48,72 and 96 h LC_(50) of alkalinity was 10.3,9.0,7.9 and 6.6 g/L respectively,and safe concentration 2.1 g/L.The joint effects of salinity and alkalinity were analyzed by uniform design.It was found that the toxicity of alkalinity was stronger than that of salinity,and sal-alkalinity worked antagonistically during different periods.Therefore there will be better future for oriential weatherfish culture in sal-alkality soil and brackish water. |
