This study was carried out to assess changes in  the electrolytes of fish during exposure to these extracts. The results obtained, indicated that the two anaesthetics caused a significant alterations (P <0.05) in the electrolytes which include Calcium (Ca2+); Sodium (Na+); Potassium (K+); Chloride (Cl-­); and Bicarbonate (HC03-) in the plasma of the exposed fish. Values of  Ca2+,   K+, and Cl-­ increased significantly (P<0.05) across different concentrations of anaesthetics, while Na+ and HC03  reduced. These alterations were more pronounced during the third exposure of C.gariepinus to these anaesthetics.
