四种常用渔药对泥鳅苗种急性毒性试验
The Acute Toxicity of Four Aquacultural Chemicals to the Fingerlings and Fry of Loach
摘要
Abstract
The single factor experiment of static acute toxicity tests showed that the LC50 in 24 hours,48 hours and 96 hours of copper sulfate for loach fingerlings and fry were respectively 0.702, 0.587, 0.509 mg/L and 1.810, 1.412, 1.270 mg/L, the safety concentrations were 0.05 mg/L and 0.13 mg/L; the LC50 in 24 hours ,48 hours and 96 hours of ferrous sulfate for loach fingerlings and fry were respectively 12.472, 9. 819, 8.297 mg/L and 24.876,19.024, 16. 833 mg/L, the safety concentrations were 0. 83 mg/L and 1.68 mg/ L. The LC50 in 24 hours, 48 hours and 96 hours of glutaraldehyde for loach fingerlings and fry were respective ly 13.286,13.264, 12.319 mg/L and 45.101, 42.701, 40.547 mg/L, the safety concentrations were 1. 23 mg/L and 4.05 mg/L. The LC50 in 24 hours 、48 hours and 96 hours of calcium oxide for loach fingerlings and fry were respectively 102.609, 102.299,98.815 mg/L and 119.345, 117.288, 114.305 mg/L, the safety concentrations were 9. 88 mg/L and 11. 43 mg/L. In the stage of loach fry, the degrees of drug sensitivity were in the order as follows: copper sulfate > ferrous sulfate > glutaraldehyde > calcium oxide.关键词
