Abstract

The common carp (Cyprinus carpio L., 1758) was exposed to sublethal concentrations of cadmium (0.05, 0.1, 0.5 and 1.0 mgl^{-1}) for 10 days. The levels of serum glucose and glycogen reserves in the liver and muscle tissues were measured both in fish exposed and not exposed to Cd. The levels of glycogen reserves in the liver and muscle tissues were significantly (P < 0.05) decreased in fish exposed to sublethal concentrations of Cd compared with the levels measured in the control groups. The decrease in glycogen levels in the liver and muscle tissues under the highest metal concentration (1.0 mgl^{-1}) were 24% and 29%, respectively. The blood serum glucose levels of fish exposed to Cd were significantly (P < 0.05) increased compared with the levels measured in the control groups. This increase was correlated with the increase in water Cd concentrations.
