在室内常温、静水条件下四种药物对太湖秀丽白虾的急性毒性大小依次为高锰酸钾>三氯异氰尿酸>硫酸铜硫酸亚铁合剂(5∶2)>二溴海因粉,其安全浓度分别为0.13、0.14、0.62、21mg/L。高锰酸钾及三氯异氰尿酸对秀丽白虾的毒性较大且安全浓度较低,应慎用。二溴海因毒性最弱,是秀丽白虾疾病防治的良好药物。
The acute toxicity of four kinds of drugs to the white shrimp of Taihu Lake at room temperature and still water were potassium permanganate> trichloroisocyanuric acid> copper sulfate ferrous sulfate mixture (5: 2)> dibromohydrin powder, The safe concentrations were 0.13,0.14,0.62,21 mg / L. Potassium permanganate and trichloroisocyanuric acid on the toxicity of white shrimp larger and lower safety concentrations should be used with caution. Dibromo-Hine is the weakest and is a good medicine for the prevention and treatment of the disease.
