ABSTRACT

The freshwater fish, Catla catla were exposed in various doses of 0.195, 0.39 and 0.78 ml/lit of dimethoate (Rogor) pesticide for 7, 14 and 21 days duration. The effect of dimethoate pesticide on the gills was observed. The gills showed damaged and ruptured. Acid phosphatase are known as inducible enzyme whose activity in animal tissues goes up when there is a toxic effect and enzymes begin to counteract. The effect of dimethoate on gills significantly changed the cell and fish activities were reduced in experimental, but in control fishes value was maximum. It was in turn an indication of toxic effect of dimethoate on acid phosphatase activities was shortened. Detailed results are summarized in the present paper.

Key words : Acid phosphatase, Dimethoate, Freshwater fish-Catla catla.
