Macro – nutrients of cichlid fishes in lake Timsah, Egypt

Resumen

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.
