Healthy medium sized females of Channa punctatus (Bloch), Catla catla (Hamilton) and Labeo rohita (Hamilton) were selected and exposed to the ascending concentration of monocrotophos. LC50 was recorded at 5 ppm in 96 hrs. The enzyme study was carried out under 1 ppm to 5 ppm at 96 hrs. Quantitative estimation of acid phosphatase, alkaline phosphatase, creatine phosphokinase, lactate dehydrogenase, serum glutamate oxalo acetate transminase and serum glutamate pyruvate transaminase was done in blood serum of the experimental fishes. The control fish data revealed highest enzyme activity whereas dose dependent decrease of enzyme activity was observed in the treated groups. This may be due to the disruption of the entire protein metabolic activity. The restlessness, aggressive nature, secretion of mucous and suffocation of fishes during the experimental period may be due to the action of monocrotoi/.ios on the tested phosphatase, kinase, dehydrogenase and transaminases.
