A comparative study was conducted on concentration of heavy metals Hg, Cd and Pb in the muscle and of Otolithes ruber in Boshehr and Bandar-e-Emam Khomeini Sea Ports in Iran from Persian Gulf. In this study used 42 samples of Otolithes ruber from Sea Ports. Metals were extracted from the tissues using wet digestion method and concentrations of the heavy metals were measured by Atomic Absorption Spectrophotometer. Analyses of the datas were done by helping of the SPSS17 software and analyse of the t-test. Concentration of Cd and Pb in the muscle of Otolithes ruber in Boshehr and Bandar-e-Emam Khomeini Sea Ports significant difference between (P<0.05), but level of Hg no significant difference between them (P>0.05). Metals of Hg, Cd and Pb in the muscles of Otolithes ruber from Bandar-e-Emam Khomeini were 0.04±0.008, 0.28±0.035 and 0.44±0.044 mgKg -1 wet weight. The results showed Concentration of Cd and Pb higher than in the muscle of Otolithes ruber from Bandar-e-Emam Khomeini Sea Port. Concentration of Hg and Pb in the muscle of Otolithes ruber was lower than comparison of WHO, MAFF, NHMRC, but Concentration of Cd higher than comparison of WHO, MAFF, NHMRC.
