Abstract
Toxicity of cadmium on some metabolic processes can lead to disturbances and imbalance of
various physiological, biochemical and cellular processes both in human and aquatic organisms.
The present study reflects the effect of cadmium chloride on carbohydrates in some vital organs
of the fresh water Indian cat fish C. batrachus. The fishes 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 LC
50they were treated with sub lethal concentration of cadmium
chloride (4.0 µg/mL) for 24, 48, 72 and 96 h. The concentration of carbohydrates declined in
various organs of C. batrachusin the following order. - liver (76.2%) > muscle (72.0%) >brain
(69.4%) >kidney (62.2%) >gonad (58.8%) as against an increase in control fish. In check, the
carbohydrate level increased in the gonad (0.265mg/100mg)
