Fish is consumed as food by many species, including humans. Water pollution and fish contamination remain significant problems. In the present work the concentration of heavy metals ( Lead, Copper, Chromium and Iron) in contaminated sea water of Red tilapia (hybrid) rearing tank and their bioaccumulation in different tissues of Female Red tilapia were investigated and compared with the values obtained from the tissues of fish reared in a tank contained hatchery managed filtered sea water. The results showed a direct relationship between the heavy metal levels in contaminated sea water and their accumulation in soft tissues of red tilapia. Concentration of lead and chromium in muscles were found higher than the maximum permissible limit. This situation may pose health risk to fish population and an ultimate threat to humans.
