Evaluation of Carbohydrate Content in Various Tissues of Fresh Water Carp (Cyprinus carpio) under the Effluent Stress

Abstract

The present study was carried out to determine the effect of sub-lethal concentration of treated textile bleaching effluent on the carbohydrate content in gill, liver, muscle and intestine of Cyprinus carpio after 28 days of exposure. A Significant decrease in carbohydrate content was observed in muscle, gill, liver and intestine of effluent treated fish compared to control fish. Liver tissue showed maximum decline in carbohydrate content followed by muscle, intestine and gill. Reduction in carbohydrate content could have happened by increased utilization of it under chronic stress by rapid glycogenolysis or by the inhibition of glycogenesis. In conclusion, the treated textile bleaching effluent containing toxic contaminants induced stress and reduced the nutritive value of fish.
