Abstract :

The fresh water fish Labeo rohita was exposed to the pesticide Imidacloprid, a nicotiniod Insecticide and determined the static and continuous flow through acute toxicity of the test toxicant for 24, 48, 72, and 96 hours. The per cent and probit values were taken and the LC₅₀ values were calculated by Finney’s probit analysis. The feeding of the test fish was stopped one day prior to the experimentation. The static LC₅₀ values were 662.2 ppm,654.6 ppm, 605.0 ppm, and 574.0 ppm respectively for 24, 48, 72 and 96 h. The continuous flow through values were 571.6 ppm, 538.7 ppm,527 ppm^, and 509.7 ppm respectively for 24, 48, 72 and 96 h. The biochemical changes were estimated by following the standard protocols. Significant biochemical changes in different tissues were observed. The results obtained were discussed with the available literature
