Abstract

The effect of sublethal concentrations 0.85, 1.20 and 1.53 mg/L of the organophosphate pesticide Dimethoate (Rogor) on the gonadosomatic index of the fish, Cyprinus carpio communis was studied. The Ganado somatic index increased in all control and pesticide treated groups in the investigation but reduction in Gonad somatic index was observed on exposure to the test substance, Dimethoate as compared to control groups. It may be also noted that the reduction in GSI values was maximum at highest concentrations of the organophosphate pesticide in ovaries of the Dimethoate treated fish showed histomorphological disorders. Furthermore, the reduced GSI was found directly proportional to the pesticide concentration and the duration of the exposure.
