ABSTRACT
The effect of pesticides on phosphatase activity is very much limited in fishes. Acid and alkaline phosphatases
are known as inducible enzymes whose activity in animal tissues goes up when there is a toxic impact and the enzymes
begin to counteract. The enzymes activity may begin to drop either as a result of having partly or fully countered the toxin
and cells also damaged. Alkaline phosphatase activity was found in the gills decreased in experimental fishes, but in
control fishes, its value was maximum. Enzymes activities were reduced. Detailed results are summarized in the present
paper.
Key words :Alkaline phosphatase,Dimethoate, Freshwater fish Catla catla.
