| 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.
