采用急性攻毒的方法,研究黄姑鱼对硫酸铜、福尔马林的耐受性。结果表明:硫酸铜对黄姑鱼的半致死浓度TLm12、TLm24、TLm48、TLm72、TLm96分别为7.81、4.39、3.78、2.33、2.06 mg/L,安全浓度为0.84 mg/L;福尔马林对黄姑鱼的半致死浓度分别为354.1、236.7、177.8、111.0、105.7 mg/L,安全浓度为30.10 mg/L。试验证实硫酸铜和福尔马林是安全、有效的驱虫剂。
Acute challenge method, the yellow croaker on copper sulfate, formalin tolerance. The results showed that the semi-lethal concentrations of copper sulfate to yellow soleus were 7.81, 4.39, 3.78, 2.33 and 2.06 mg / L, respectively, and the safe concentrations of TLm12, TLm24, TLm48, TLm72 and TLm96 were 0.84 mg / The median lethal concentration of yellow croaker was 354.1,236.7,177.8,111.0,105.7 mg / L, the safe concentration was 30.10 mg / L. Tests confirm that copper sulfate and formalin are safe and effective insect repellents.
