摘要： 目的 观察四聚·杀螺胺灭螺药致死鲫鱼对雏鸭的急性毒性,为我省血防药物灭螺工作提供技术支持。 方法 将 20 只生长满 60 d 的雏鸭随机分为试验组和对照组,分别喂食用有效含量 20 g / L 四聚·杀螺胺毒杀的鲫鱼 和离水自然死亡的鲫鱼,每只雏鸭喂食 40 g 鱼肉。 观察两组雏鸭食用后反应及其后一周体重增长状况。 结果 试验组雏鸭在喂食后 6 h 未出现不良反应,试验组和对照组雏鸭在试验前(t = -0. 873,P = 0. 394)和试验后(t = 0. 973,P = 0. 343)的平均体重差异均无统计学意义。 结论 本次试验未观察到四聚·杀螺胺致死鲫鱼对雏鸭存在急性毒性作用。

Abstract: Objective To observe the acute toxicity in ducklings resulted from intake of crucian contaminated by sus- pension concentrate of metaldehyde and niclosamide(MNSC) for technical support for snail control with drugs in our prov- ince. Methods Twenty duckings of 60 days old were randomly divided into test group and control group. Ducklings in the test group were given crucian killed by MNSC in effective dose of 20 g / L, and those in the control group were fed with crucian naturally died from water. Each duckling in both groups was dosed with 40 g of the fish meat, and observed for the simultaneous reaction upon intake and increase of body weight one week after intake. Results No toxic reaction occurred in the ducklings in the test group in 6 h after intake, and the average body weight remained no significant difference before test(t = -0. 873, P= 0. 394) and after test( t = 0. 973, P = 0. 343) in both groups. Conclusion Acute toxicity of MNSC appears free in our ducklings after intake of the contaminated crucian.
