Impact of Paper Mill Effluent on Carbohydrate Metabolism of Freshwater Snake Headed Fish, Channa punctatus (Bloch, 1793)

Abstract

The snake-headed fish, Channa sp. Bloch (Actinoptrygii: Channidae) is animportant component of inland fishery in the Indian subcontinent and one of the fashionable commercial fish. The industrialized effluents’ accomplishment to the aquatic ecosystem is one of the foremost causes of environmental pollution, and its hazardous influence on the exposed edible fishes may be a serious threat to human health. The present investigation has been designed to study the effects of sublethal concentrations of paper mill effluent on the serum glucose, serum lactic acid, liver glycogen, and liver lactic acid contents of Channa punctatus (Bloch) after in vitro exposure for96 hours. The investigation recorded a significant increase in serum glucose, serum lactic acid, and liver lactic acid contents with a significant quantitative decline in liver glycogen among effluent exposed fishes were recorded during the investigation. Thus the authors supposed to propose that the carbohydrate metabolism of freshwater snake-headed fish, C. punctatus affected during effluent exposure based on their experimental findings.
