Abstract: The Indian Cat fish Heteropneustes fossilis (Bloch) was exposed to sub lethal concentration (Lc50) of cadmium (3.21ppm) for 10 days. The level of serum glucose and glycogen reserves in liver and muscle tissues were calculated in both fish treated and untreated to Cd. The level of glycogen reserve in liver and muscle tissue were significantly (P < 0.05) decreases in fish exposed to sublethal concentration of Cd in comparison to the level of the same in the control group. This depletion of glycogen level in both liver and muscle tissue under the highest metal concentration (1.0 mgl-1) were 26% and 31% respectively. The blood serum glucose level of fish exposed to Cd were significantly (P < 0.05) increases compare with that of level measured in control group. Perhaps this increase was correlated with the increase in water Cd concentration.
