ABSTRACT: Diet composition and feeding relationships of three cyprinid species, C. luteus, C. carpio and C. auratus from the Shatt Al-Arab River, Iraq, were assessed during 2016-2017. Fish were collected by gill nets, cast net and electro-fishing. The index of relative importance (IRI%) of food item was determined by combined the frequency of occurrence and points methods. There were monthly variations in feeding activity and intensity of all species, which decreased in the colder months. All species were omnivorous and C. carpio was a low specialized feeder, while C. auratus and C. luteus were generalized feeders. The diet of C. luteus primarily comprised algae (24.3%), aquatic insects.........
