Background and objective: Clarias lazera is an important fish species lives in River Nile and its tributaries. The present study was to assess the levels of waste water heavy metals and its effects on enzyme activities in Clarias lazera fish species. Materials and methods: Ethanol extract was taken for the determination of cholesterol and 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 the muscle extract of the tested samples and control. GOT, LDH and amylase levels were found to be higher in treatment pond sample than in control. 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: In spite of being not significant to control, long-term accumulation of heavy metals in the tested fish species could potentially affects muscles enzymes' activities.
