采用急性攻毒的方法,对双棘黄姑鱼进行硫酸铜、福尔马林等两种水产养殖常用驱虫药物的毒性试验,研究其耐受性。结果表明:硫酸铜对双棘黄姑鱼的半致死质量浓度TLm12、TLm24、TLm48、TLm72、TLm96分别为12.6、5.12、4.37、3.18、2.56 mg/L,安全质量浓度为0.96 mg/L;福尔马林对双棘黄姑鱼的半致死质量浓度分别为396.5、317.5、288.4、195.6、156.6 mg/L,安全质量浓度为71.39 mg/L。表明硫酸铜、福尔马林是安全、有效的驱虫剂。
The acute toxicity test was used to test the toxicity of two commonly used deworming drugs such as copper sulfate and formalin for aquaculture. The results showed that the LC50 of TLm12, TLm24, TLm48, TLm72 and TLm96 of copper sulfate were 12.6, 5.12, 4.37, 3.18 and 2.26 mg / L respectively, and the safety mass concentration was 0.96 mg / The semi-lethal concentrations of cercariae were 396.5, 317.5, 288.4, 195.6 and 156.6 mg / L respectively, and the safe mass concentration was 71.39 mg / L. Show that copper sulfate, formalin is a safe and effective insect repellent.
