The current study investigated the comparison of the biochemical composition of the common carp Cyprinus carpio L.

which collected from four different sources in Basrah city; Shatt Al-Arab river at Abul- Khasib by using gill nets, earthen ponds at the University of Basrah campus, fish cages at Al-Hartha district and cooled fish imported from the Islamic Republic of Iran.

Fifty specimens of each fish source were selected for analysis, half of which was stored with ice for up to ١٠days.

The results indicated that higher moisture content 78.2% was in the muscular tissues of Shatt Al-Arab fish.

Highest fat content 11.9% was recorded in imported fish, highest protein 18.17% and ash 2.29% were measured in fresh pond fish.

Caloric value of the examined fish showed variations between fresh and iced fish where the highest value 165.62 Kcal/ 100 gm was recorded in fresh cage fish.
