5种常用鱼药对黑尾近红鲌鱼种的急性毒性实验

Acute Toxicity of Five Aquacultural Chemicals towards Fingerlings of Ancherythrpterus nigrocauda

在常温静水条件下,用硫酸铜与硫酸亚铁合剂(比例5∶2)、高锰酸钾、晶体敌百虫、强氯精、溴氯菊脂等5种常用水产药物对黑尾近红鲌鱼苗进行急性毒性试验。试验结果表明,安全浓度最高的是高锰酸钾为0.738mg/L,安全浓度最低的是溴氯菊脂为0.0033mg/L,5种常用水产药物对黑尾近红鲌鱼苗都比较敏感,药物的敏感性大小依次为:溴氯菊脂>强氯精>敌百虫>硫酸铜与硫酸亚铁合剂>高锰酸钾。

This paper reports the susceptibility of Ancherythroculter nigrocauda to five medicines including cupric sulphate ＆ ferrous sulphate （ratio 5：2 ） , potassium permanganate, trichlorphon, strong-chloride and bromochloropropene in tanks with static water. The results show that a safe concentration of potassium permanganate was 0. 738 mg/L and had the lowest toxicity to A. nigrocauda, but a safe concentration of bromochloropropene was 0. 0033 mg/L and had the highest toxicity to A. nigrocauda. The susceptibility of A. nigrocauda to the five medicines is in the order of Bromochloropropene 〉 strongchloride 〉 trichlorphon 〉 cupric sulphate ＆ ferrous sulphate （ ratio 5：2） 〉 potassium permanganate.
