Background and Aim: Anthropogenic processes, in particular industrial, continuously increase the amount of heavy metals in the environment, especially in aquatic ecosystems. On the other hand, organs of aquatic animals may accumulate heavy metals when exposed to toxic concentrations. Several toxic elements can be bioaccumulated via the food chain and finally be assimilated by human marine food consumers involving health risks. In order to determination the heavy metals concentration (Zn, Cu) in muscle tissues of two edible fishes Pampus argenteus and Liza klunzingeri were collected from mangrove conservation area located in the Hormozgan province of Iran. Methods: In this investigation, 72 fish of the Liza klunzingeri and 54 fish of the Pampus argenteus were captured for determination the heavy metals concentration in muscle tissues. Results were expressed as microgram of metal per gram. Metal analyses were performed using a graphite furnace atomic absorption spectrometer (model AA3030 Perkin Elmer). Statistical analyses were carried out using the SPSS statistical package program. 
Results: Metal concentrations average in the muscle were 6.69 and 0.92 micrograms per gram in the Pampus argenteus and 3.5 and 0.55 micrograms per gram in the Liza klunzingeri respectively. Also, the results show that the mean concentrations for metals were lower compare to international standards. 
Conclusion: The present results showed that, these fishes, based on the lower levels of metal accumulation, could be safe for human consumption.
