title: The effect of Chlorpyrifos, an organophosphate in acetyl cholinesterase activity in freshwater fishes.
abstract: The freshwater fish Catla catla, Labeo rohita and Cirrhinus mrigala are exposed to the toxicant chlorpyrifos, an organo phosphate commonly used in agriculture as well as in aquaculture. The effect was studied on the enzyme acetyl cholinesterase activity which was inhibited in the selected tissues of the fish. In different tissues and in brain, the maximum inhibition was observed.
