在水温 2 6~ 30℃下 ,敌百虫等十种常用药物对小口脂鲤夏花鱼种的安全浓度分别为 :敌百虫 0 .0 4 2 mg/ L、甲醛 18.2 0 mg/ L、硫酸铜合剂 0 .98mg/ L、孔雀石绿 0 .0 35mg/ L、高锰酸钾0 .93mg/ L、鱼虫克星 0 .0 37mg/ L、强氯精 0 .13mg/ L。呋喃唑酮、土霉素、亚甲基蓝的试验最高浓度分别为 6 4 mg/ L、6 4 mg/ L、8mg/ L,在此浓度下 ,2 4 0小时内小口脂鲤夏花鱼种全部存活。以安全浓度作为衡量标准 ,小口脂鲤夏花鱼种对上述药物的敏感性依次为 :孔雀石绿 >鱼虫克星 >敌百虫 >强氯精 >高锰酸钾 >硫酸铜合剂 >甲醛。其中孔雀石绿、敌百虫的安全浓度仅为常用浓度的 10 %~ 30 % ,故不宜使用。鱼虫克星、强氯精的安全浓度较低 ,在疾病防治中可谨慎使用。
Under the water temperature of 26 ~ 30 ℃, the safe concentrations of trichlorfon and other 10 kinds of commonly used drugs on the small mouth carp Cyprinus carpio species were: trichlorfon 0 .042 mg / L, formaldehyde 18.2 0 mg / L, Copper sulfate mixture 0.98mg / L, malachite green 0. 35mg / L, potassium permanganate 0.93mg / L, nematode 0. 0 37mg / L, strong chlorine 0.13mg / L. The highest concentrations of furazolidone, oxytetracycline and methylene blue were 64 mg / L, 64 mg / L and 8 mg / L, respectively. All the species of summer carp larvae survived within 240 h at this concentration. Taking the safe concentration as the standard, the sensitivity of Xiaoyelian Lei carp species to the above drugs were as follows: malachite green> nematode> trichlorfon> strong chlorine> potassium permanganate> copper sulfate mixture> formaldehyde. Which malachite green, trichlorfon safe concentration of only 10% to 30% of the commonly used concentrations, it is not appropriate to use. Fish nemesis nemesis, strong chlorine concentration of the lower security, disease prevention and treatment can be used with caution.
