MACRO – NUTRIENTS OF CICHLID FISHES IN LAKE TIMSAH, EGYPT

Cichlid fishes are one of the highly economic fishes in Egypt. The study aims to determine the macro – nutrient content for (K, Na, P, Ca, and Mg) of (Oreochromis niloticus, Coptodon zillii, Oreochromis aureus, and Sarotherodon galilaeus) in Lake Timsah, Egypt. Among studied species, S. galilaeus possesses the highest values of nutrients except Ca while O. niloticus possesses the lowest values except P and Ca. For elements,1057 mg/Kg of Mg was the highest while 36 mg/Kg of Ca was the lowest. The conclusion is cichlid fishes have a high nutritional value with remarkable differences among studied species
