摘要
采用静水生物测试法,在水温24～27℃条件下,研究硫酸铜和高锰酸钾对花幼鱼的急性毒性。结果显示,硫酸铜对花幼鱼的LC50(24h)、LC50(48h)、LC50(96h)、安全质量浓度值分别为0.242、0.196、0.196和0.0 386mg/L,高锰酸钾对花幼鱼的LC50(24h)、LC50(48h)、LC50(96h)、安全质量浓度值分别为1.83、1.37、1.19和0.23mg/L。2种药液对花幼鱼的毒害作用都比较大,使用时存在中毒风险。花鱼幼鱼对硫酸铜的敏感度大于高锰酸钾,在水产生产中不建议采用硫酸铜,高锰酸钾应谨慎使用。
In a water temperature of 24～27℃ condition,Acute toxicity of Copper sulphate and Potassium Permanganate to larval of Hemibarbus maculates were studied by Stagnophile toxic Test method.The results showed that the LC50（24h）,LC50（48h）,LC50（96h）,safe concentration of Copper sulphate are respectively 0.242,0.196,0.196,0.0 386mg/L;the LC50（24h）,LC50（48h）,LC50（96h）,safe concentration of Potassium Permanganate are respectively 1.83,1.37,1.19,0.23mg/L.Poisonous effect of two solutions to Hemibarbus maculates are large comparatively and two solutions exist poisoning risk,The sensibility of larval of Hemibarbus maculates to Copper sulphate washigher than that of potassium permanganate,so Copper sulphate were not recommended to introduce and potassium permanganate should were used carefully in aquaculture.
