中文摘要: |
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。 |
英文摘要: |
The acute toxicity of the mixture of copper sulphate and ferrous sulphate (ratio 5: 2), potassium permanganate ( KMnO4 ) , trichlorphon ( C4H8O4 C13P) , 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. 500mg/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. |
