In this study, selected biochemical parameters including the activities of lipid peroxidation in fish
exposed to varied percentages of aqueous extract (AE) of Nigerian Crude Oil (Bonny light) were assessed. The total
Hydrocarbon and Polycyclic Aromatic Hydrocarbon contents of the AE were 124.1mg/l and 16.9mg/l respectively.
Results of the levels of glucose, total protein, albumin, aspartate aminotransferase and alanine aminotransferase in
fish exposed to 10.0% AE were 46.2
mm, 9.18g/dl, 5.13 g/dl, 62.6 IU/l and 18.3 IU/l, respectively. Also, the average
concentrations of malondialdehyde obtained in
Clarias gariepinus
exposed to 10% AE was 5.84 nmol. In general,
the concentrations of the selected biochemical indices studied were higher in test fish exposed to 10.0% AE, followed
by those of the lower concentrations. These findings suggest that exposure of
Clarias gariepinus to low levels of AE
of Nigerian Crude Oil would result in chronic oxidation stress, cellular membrane damage and death of cell. @
