Abstract: The present work was designed to determine toxicity on carp Cyprinus carpio exposed to Cadmium Chloride and the effect of carbohydrate metabolism changes observed during both lethal and sub-lethal concentration. Acute toxicity LC50 of Cadmium Chloride detected 14mg/L and 1/5th, i.e. 2.8 mg/L of the acute toxicity selected as sub-lethal for sub-acute test concentration. The current experiment to study the impact of Cadmium Chloride on certain aspects of carbohydrate metabolism were studied and estimated the levels of activities of glycogen phosphorylase, glucose-6-phosphatase, LDH (lactate dehydrogenase) and SDH (succinate dehydrogenase) in the fish organs like gills, liver and kidney of the Cyprinus carpio. Exposures of the lethal and sub-lethal concentrations of Cadmium Chloride taken at different exposure periods were considered. The main effects were studied during experimental tenures and the results were obtained in the present study which indicates clearly that the carbohydrate metabolism is disturbed when the fish, Cyprinus carpio is exposed to Cadmium Chloride. The results were seen to be valuable tool that should be incorporated to a battery of biomarkers.
