Abstract : The pollution of environment due to use of pesticides has become an increasing problem over the last century with the development of industry, agriculture and increase in population. The organophosphate pesticides are widely used because of their rapid biodegradability and non-persistent nature. Changes occurring in the haematological characteristics provide a sensitive measure to assess the fish health. Pesticide is a major factor for fish mortality along with water temperatures. The main purpose of the study was to show the vital effect of organophosphate pesticides in the ovulation of air breathing fish.
