The distribution patterns of some heavy metals (Fe, Mn, Zn, Cu, Pb and Cd) in water, sediment, some fish species and fish diets in Fish Farm were studied during 2003. The results revealed that, with exception of zinc the values of heavy metals were exceeded that of the permissible limits in water. The descending order of heavy metals was: Fe> Mn> Pb> Zn> Cu> Cd for water, while for sediment the order was: Fe> Mn> Zn> Cu> Pb> Cd. Heavy metals in the fish flesh showed that Mugil sp. tended to accumulate more concentration of (Cu, Zn, Pb, and Cd) than Tilapia sp. The diets were considered as additional ambient heavy metals sources.
