MICRO – NUTRIENTS OF RED – BILLY TILAPIA (COPTODON ZILLII) AMONG DIFFERENT EGYPTIAN WATER MASSES

Fishes concentrate heavy metal from surrounding environment inside their tissues. The study aims to determine the micro –nutrient contents (Cu, Fe, Mn, Pb) of Coptodon zillii in Bardwail Lagoon, Mediterranean Sea, Brackish Water Lagoon and Lake Timsah. The results showed that the highest nutrients were in Brackish Water Lagoon while the lowest ones in Mediterranean Sea site. Considering to nutrients, the highest value was 36.2 mg/ Kg of Fe while the lowest value was 0.57 mg/ Kg of Mn. The study approved the high – nutrition value of Coptodon zillii and healthy minerals content minerals among its flesh
