Biochemical alterations due to carbaryl exposure in glucose content of liver and alimentary canal of Clarias batrachus

Abstract

Pesticides provide useful tools to agriculturists and hygienist for crop protection and disease control. The use of pesticides has undoubtedly increased the agricultural output, but on the other hand, they have also poisoned the aquatic environment. Present study indicates that carbaryl is highly toxic to fi sh. It produces severe damage to the organs: alimentary canal and liver, concerned with the digestion and absorption of glucose. Due to this, glucose metabolism was signifi cantly affected throughout the exposure period. Carbaryl intoxication reduced glucose content both in liver and alimentary canal after an initial increase, generally more energy is needed to mitigate any stress conditions. This may be obtained from glucose which is one of the most available sources of energy. All these changes in glucose content may be due to cumulative effect of enzymes, hormones, and metabolic disturbance caused by the pesticide.
