Abstract: The objective of this study was find out the concentrations of Zn, Cu, Pb and Cr in the muscles, gills, and liver of Mugil cephalus from the Kollidam estuary, Tamilnadu. Results were shown that metal bioaccumulation in the liver was higher than in the gills and muscles for all metals, and Zn concentration was higher than Cu, Pb, and Cr in all the tissues studied. The accumulation of heavy metal gradually increases in organs during different month period. The order of heavy metal concentrations of estuary water in the each site was higher levels to Cu
