摘  要:
在水温29~30℃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、甲醛共6种药物对厚颌鲂(Megalobrama pellegrini)鱼苗进行急性毒性试验。试验结果显示,6种药物48h的半致死浓度分别为5.78、6.50、4.90、2.55、0.042、120mg/L,安全浓度分别为0.445、0.528、0.268、0.190、0.003、7.500mg/L,厚颌鲂鱼苗对药物敏感性比一般鱼类高,实际用药时应根据具体情况确定用药时间和用药量,溴氯菊脂不宜作为治疗药物。

摘  要:
The acute toxicity of the mixture of copper sulphate and ferrous sulphate(ratio 5∶2),potassium permanganate(KMnO4),trichlorphon(C4H8O4C13P),strong-chloride,bromochloropropene and formalin towards Larva of Megalobrama pellegrini was studied at by biological toxic test method at the water temperature of 29℃ to 30℃.The results showed that the median-lethal concentrations of 48h were 5.78、6.50、4.90、2.55、0.042、120 mg/L,respectively;the safe concentrations were 0.445、0.528、0.268、0.190、0.003、7.500 mg/L,respectively.The larva of Megalobrama pellegrini is more sensitive than other fish,bromochloropropene can`t be used.The drug dosage and time should be based on the specific situation circumstances in production.
