Zinc in the fish samples accumulated in the order Upeneus vittatus , Pomadasys maculates , Ambassis commersoni , Lutjanus adetii , Anchoviella commersonii. The high concentration of zinc in the muscles of the fish samples is mainly due to the presence of a large number of fishing vessels and trawlers which use galvanized metal coatings to prevent rusting, that ultimately find it's way into the ambient media through leaching. The high Zn concentration in gonads was because Zn is a necessary element for embryo development and is important to reproductive organs(Carpenc et al., 1994
