摘要:
为进行银盾鱼病害防治药物的选择及安全性评价,研究17种常用渔药物对银盾鱼稚鱼的急性毒性。结果表明,17种药物对美国银盾鱼的安全浓度按从高到低的顺序排列为:食盐(220 mg·L-1)、乙酰甲喹(16.75mg·L-1)、百虫克(10.72mg·L-1)、霉菌净(7.98mg·L-1)、氟苯尼考(7.52mg·L-1)、甲苯咪唑(3.44mg·L-1)、甲醛(3.16mg·L-1)、高聚碘(1.94mg·L-1)、高锰酸钾(1.07mg·L-1)、鱼虫克星(0.76mg·L-1)、小瓜指环净(0.39mg·L-1)、敌百虫(0.35mg·L-1)、拜特虫清(0.32mg·L-1)、新伊维(0.3mg·L-1)、三氯异氰脲酸钠(0.06 mg·L-1)、拜特鱼虫敌(0.03 mg·L-1)、硫酸铜(0.028mg·L-1)。甲苯咪唑、百虫克、敌百虫、拜特鱼虫敌、拜特虫清、新伊维、小瓜指环净、高聚碘、霉菌净、氟苯尼考、乙酰甲喹的安全浓度分别接近或高于常用剂量,可安全使用;三氯异氰脲酸钠、甲醛、高锰酸钾、鱼虫克星和食盐的安全浓度低于常用剂量,应谨慎使用;硫酸铜的安全浓度显著低于常用剂量,应避免使用。

Abstract:
For medicine selection and safety assessment of disease control of Pomoxisnigromacufastus,the acute toxicity test of seventeen aquaculture drugs were done for Juvenile Pomoxis nigromacufastus.The results showed that the safety concentrations of seventeen aquaculture drugs from the highest to the lowest were natrii chloridum(220mg·L-1),mequindox(16.75 mg·L-1),baichongke(10.72 mg·L-1),meijunjing(7.98 mg·L-1),florfeniol(7.52mg·L-1),mebendazolum(3.44 mg·L-1),liquor formaldehyde(3.16 mg·L-1),polyiodide(1.94mg·L-1),kalii permanganas(1.07mg·L-1),yuchongkexing(0.76mg·L-1),xiaoguazhihuanjing(0.39mg·L-1),trichlophonus(0.35 mg·L-1),baitechongqing(0.32 mg·L-1),xinyiwei(0.3 mg· L-1),trichlorinafed isocyanuric acid(0.06 mg·L-1),baiteyichongdi(0.031 mg·L-1),and cupric sulfate(0.028mg·L-1).The safety concentrations of cupric sulfat for Juvenile Pomoxis nigromacufastus were significantly lower than commonly used concentrations.Cupric sulfate cannot be used to cure the disease of Juvenile Pomoxis nigromacufastus. The safety concentrations of Trichlorinafed isocyanuric acid,Liqour formaldehyde, Kalii permanganas,Yuchongkexing and Natrii chloridum for Juvenile Pomoxis nigromacufastus were lower than their commonly used concentrations,so they should be used carefully.The safety concentrations of eleven kinds of drugs of mebendazolum, polyiodide, meijunjing, baichongke, xiaoguazhihuanjing, xinyiwei, baitechongqing,trichlophonus, mequindox,florfeniol and baiteyichongdi were near or higher than their commonly used concentrations,so they could be used safely in cultivation of Pomoxis nigromacufastus.
