ABSTRACT
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.
