摘要
Abstract
[Objective] The research aimed to provide scientific basis for the use and control of cypermethrin in different salinity. [ Method] U-sing static bioassay test, the acute toxicity effect of cypermethrin on Litopenaeus vannamei in different salinity were studied. [ Result ] 24, 48, 72, 96 h LCX of cypermethrin to L vannamei in the salinity of 20 and 5 were 0.767, 0.440, 0.383, 0.038 2 |xg/L and 0.437,0.313,0. 203 and 0.170 fig/L respectively. In medium and low salinity, the safe concentration of cypermethrin to L. vannamei was 0.038 2 and 0.017 0 p.g/L respectively. [Conclusion] Very low concentrations of cypermethrin pesticide residues might threaten the safety of L. vannamei culture, so the use of cypermethrin should be reduced as possible in shrimp pond and its surrounding area.关键词
