Effects of herbicide, glyphosate on behaviour response & blood metabolite of Clarias batrachus (Linn.)

Abstract

The present investigation includes the blood biochemical alterations in chronic (30 days) exposure of the airbreathing fish, Clarias batrachus (Linn.) induced by sublethal concentration (2.46 mg/L) of inorganic herbicide, glyphosate. Significant changes were observed in the blood biochemical properties in the form of hyperglycemia, hypoproteinemia and hypercholesterolemia. The present study therefore points towards a severe metabolic dysfunction in response to herbicide, glyphosate toxicity in the fish Clarias batrachus. So, it is suggested that more suitable to culture at water glyphosate concentration of < 2.46 mg/L for optimum growth performance and survival rate than other water conditions.
