The electrolyte levels (Sodium and Potassium) were determined in the liver and muscle of African catfish, Clarias gariepinus exposed to various sub-lethal concentrations of paraquat dichloride (0.01, 0.02, 0.03, 0.04 and 0.05 mg/L). Sodium (Na+) decreased significantly (p<0.05) from the control as the concentration of paraquat increased, with the exception of the first experimental group (with lowest concentration of paraquat), where the liver Na+ level was significantly (p<0.05) higher than the control, while the muscle Na+ level did not vary significantly (p>0.05) from the control. Thus, the variation of Na+ tended to depend on the concentration of paraquat. On the other hand, potassium (K+) did not show any district pattern, with significantly (p<0.05) higher values at the various concentrations of paraquat than the control. However, there was no significant (p>0.05) difference between the K+ levels in both the liver and muscle of the control and those of the fifth experimental group, with the highest concentration of paraquat treatment. This pattern of variation exhibited by Na+ and K+ suggested that the fish adjusted effectively to stress within the limits of toxicant exposure used in this study.
