Effects of heavy metals [copper (Cu), zinc (Zn), chromium (Cr), nickel (Ni), manganese (Mn), iron (Fe), Aluminum (Al), cadmium (Cd), mercury (Hg), stannum (Sn), and lead (Pb)] present in Tubruk harbor (polluted site) comparing to Umm Hufayan lagoon water (control) on liver and kidney performance of Mugil cephalus captured from both sites were investigated. For this purpose, surface water samples of both chosen sites were compared in terms of heavy metals concentrations, pH, and dissolved oxygen. Mullet fish were captured from both sites and blood samples were taken from the fish and sent to the lab for liver and kidney function tests. The results showed that heavy metals levels were significantly higher in Tubruk than those in Umm Hufayan lagoon. Additionally, significantly higher total protein and albumin levels were found in the blood serum of M. cephalus of Umm Hufayan, compared to Tubruk harbor fish samples; however, higher levels of bilirubin (BR), alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), acid phosphatase (ACP), urea, uric acid, creatinine, and glucose were observed in the blood serum of Tubruk fish. Positive correlation was noticed between LDH and Cd levels (r: 0.576, p: 0.02, LDH = 0.000Cd + 0.36, R2 : 0.509) in Tubruk fish, and between AST and Hg of Umm Hufayan fish (r: 0,488, p: 0.055, AST = 0.005Hg +0.497, R2: 0.078).
