Concentration of As in the muscle and liver of Aspius vorax, Cyprinion macrostomus, Barbus luteus in Karoon River and Liza klunzingeri and Liza macrolepis from Hendijan Port, Persian Gulf, were investigated in 2011. In this study, 30 samples of fish were collected in winter. Metals were extracted from the tissues using wet the digestion method and concentration of the heavy metals were measured by an Atomic Absorption Spectrophotometer Perkin Elmer 4100. Data were analyzed using one away ANOVA. The highest concentration of As in the liver of Liza klunzingeri was 155.33±9.6 µg kg-1 dw. Also the lowest concentration of this element in muscle of Cyprinion macrostomus was 73.90±0.65 µg kg-1 dw. There was no significant difference in concentration of As in the muscle and liver tissues of Aspius vorax, Cyprinion macrostomus, Barbus luteus, but there was a significant difference in As of two species Liza klunzingeri and Liza macrolepis. Also there was a significant difference between marine and freshwater species. Concentration of As was lower than those of NHMRC and FAO standards.
