The effectiveness of the carnivorous fishes on food resources in the Northwest Arabian Gulf

Abstract

The effectiveness of thirteen carnivorous fish species on food resources in Iraqi marine waters, northwest Arabian Gulf were studied from July 1998 to June 1999. The results revealed that specialization or selectivity is common trend among predators examined, depending mainly upon shrimps and small fishes. Specialized feeding indicates a clear partitioning of food resources among components. The most effective fish species on shrimp and fish reserve were Polynemus sextarius and Saurida tumbil respectively. Shrimps seem to be the most important food item than fishes and others in the study area.
