Abstract
[Objective] The aim was to explore the acute toxicity of two common organonitrogen pesticides dimehypo and monosultap on Clarias lazera juvenile.[Method] The toxic symptoms of C.lazera juvenile were observed when they were set in different concentrations of two pesticides for 72 hours.The acute toxicity effects and the safe concentrations of dimehypo and monosultap on C.lazera juvenile were evaluated.[Result] The LC50 of dimehypo at 24 h was 272.367 mg/L,and the safe concentration was 96.640 mg/L,so it belonged to slight toxicity grade.The LC50 of monosultap at 24 h was 59.688 mg/L,and the safe concentration was 7.360 mg/L,so it belonged to moderate toxicity grade.[Conclusion] The research provides reference for the safe and reasonable water quality management of artificial breeding.
