Effects of cadmium on serum osmolality, ion levels and hematological parameters of tilapia (Orechromis niloticus) were evaluated at different salinities. Serum osmolalities (SOs) in fish unexposed to Cd (0 mg l −1 ) and exposed to 2.5 mg Cd l were not significantly different at salinities of 0, 5 and 10 g l −1 −1 −1 , while at 15 g l , SO was significantly higher than at 0, 5 and 10 g l−1 + . Levelsof Na − and Cl in serum at salinities of 5, 10 and 15 g l were not significantly different; but weresignificantly higher than those at 0 g l −1 with and without Cd. In media without Cd, the lowest level of K −1 at 0, 5 and 10 g l + in serum occurred at 15 g l -1 salinity, whereas levels of K + in Cd-exposed fish at all salinities were not significantly different. At 0 g l −1 were not significantly different. The levels of K + salinity, hemoglobin, red blood cells, and hematocrit in Cd-exposed fish were significantly lower than controls. At salinities of 5, 10 and 15 g l−1 , levels incontroland Cd-exposedfish were not significantly different indicating that higher salinity prevented Cd-induced osmotic imbalance and hematological alterations.−1
