Background and purpose: Health quality of fish as an important source of protein for human has received increasing attention. This study, examined the concentrations of chromium, nickel, zinc, and copper in the muscle and skin tissues of two edible fish species of Alosa Caspica and Clupeonella cultiventris caspia in the southern Caspian Sea in 2013. Also, the risk assessment of consumption of these species was done. Materials and methods: After biometric analysis, C. cultiventris caspia (n=50) and A. Caspia (n=17) were prepared for analysis by acid digestion method. Concentrations of the studied metals in digested samples were determined using an atomic absorption spectrophotometer (GFS97, Thermo Electron, Cambridge, UK). Results: The results showed that the level of chromium in the skin tissue of A. Caspia was significantly higher than that of the C. cultiventris caspia (P<0.05). In the C. cultiventris caspia and A. Caspia concentrations of zinc in the skin were higher than what has been found in the muscle. In the C. cultiventris caspia the muscle showed high concentrations of chromium than skin (P<0.05). In the studied specimens the concentrations of chromium and nickel exceeded the WHO threshold Conclusion: Human health risk assessment of heavy metals via consumption of studied species showed that consuming these species with current rate of contamination is not a risk for consumers
