Toxicity of cadmium on some metabolic processes can lead to disturbances and imbalance of various physiological activities. The present study reflects the effect of cadmium chloride on carbohydrates in some vital organs of the fresh water crab Barytelphusa gureini. The crabs were treated with different concentrations of cadmium chloride (2.0, 4.0, 6.0. 8.0, and 10.0 μg/mL) mortality rate was noted up to 96 h. After deducing the LC50 they were treated with sub lethal concentration of cadmium chloride ( 6.7μg/mL) for 24, 48, 72 and 96 h. The carbohydrates were estimated to study the stress caused by the cadmium chloride as a toxicant. The results showed a significant decline in the total carbohydrates in different organs and the order of the decline found to be hepatopancreas (66.2%) > muscle (62.0%) > hemolymph (powder form) (59.4%) > gill (52.2%) > gonad (48.4%) at sub lethal concentration of cadmium chloride. In contrast, there was an increase in the carbohydrate in various organs of control crabs viz gonad (0.036mg/100mg) < gills (0.070mg/100mg) < hemolymph (powder form) (0.074mg/100mg) < muscle (0.173mg/100mg) < hepatopancreas (0.211mg/100mg). The significant role of cadmium chloride in some vital organs of the experimental animal is discussed and the results correlated and corroborated with the findings of the earlier researchers.
