Abstract

The aim of the study was to assess the effect induced by Sevin a carbamate pesticide on hematological indices of Clarias batrachus check for this species in other resources . The effect was studied based on the results of acute toxicity tests and comparison of control with experimental group. The fish was exposed to varying levels of the toxicant and sub lethal exposure to varying concentrations was used to study the effect on blood cells. LC50 of Sevin for Clarias batrachus after 96hr exposure was found to be 15.3mg/l. Examination of hematological indices was performed on 6 control and 9 experimental specimens after 96hr exposure to Sevin in concentration of 12.6mg .1-1 and 14.6mg .l -1. Reduction in the number of red blood cells, erythrocytes, packed cell volume, Mean corpuscular hemoglobin, mean corpuscular volume decreased indicating Anemia.
