Background and objective: Oreochromis niloticus is a fish species locally known as Bulti, and greatly demanded in local markets. The present study was to assess the levels of heavy metals and their effects on enzyme activities in type of fish species. Materials and Methods: Ethanol extract was taken for the determination of cholesterol, total lipid contents in fish muscles. While saline extract was used for the estimation of glucose, total protein, albumin, globulin and enzyme like GOT, GPT, LDH, CPK and amylase. The concentrations of heavy metals were carried out by the flame atomic absorption spectrophotometer (UNICAM 929). Results: There were no significant differences between enzyme activities in both liver and muscle extracts except for ALP found to be lower in tested samples comparing to the control. The cadmium (Cd) level in the liver was found to be higher than that in the muscle, whereas the zinc (Zn) level in the muscle was found to be higher than that in the liver. Conclusions: the higher levels of heavy metals found in the contaminated fish samples compared to control could poses risks to human health during time.
