This study was carried out to determine and comparison of concentration metals nickel and vanadium in muscle of eight species of fish, Epinephelus coioides, Platycephalus indicus, Cynoglossus arel, Acanthopagrus latus, pampus argenteus, Tenualosa ilisha, Liza macrolepis and Liza klunzingeri from Khuzestan province in 2013. 120 samples of fish collected from Bahrekan in Khuzestan province. Chemical digest samples of fish by wet method and nickel and vanadium measured by Perkin Elmer 4100 atomic absorption spectrometry. Data were analyzed statistically using one-way ANOVA and Duncan test. In this study concentrations of nickel and vanadium in species of fish were significantly different (p<0.05). The highest of concentrations Ni was in Epinephelus coioides (0.587 mg/kg/ww) and lowest in muscle of Pampus argenteus (0.223 mg/kg/ww), respectively. The highest concentration of V was in Epinephelus coioides (0.184 mg/kg/ww) and lowest in muscleof Platycephalus indicus (0.109 mg/kg/ww), respectively. In this study concentration of V in muscle of fishes were lower than that limitation of WHO (0.5 mg/kg), but the concentration of Nickel in the muscle of fishes were higher than WHO standard limits (0.38 mg/kg).
