Two hundred sixteen filled stomach, 14 semi- filled stomach and 215 empty stomach were analyzed. Small fish and Crustaceans were constituated main and secondry foods with 51.03% and 15.66% respectively. Mollusca were random food (5.52%). VI of stomach was estimated 48.32%. This value demonstrated that this species was moderate feeder. The result of Non-Parametric Multi-Divisional Scaling, shows the stomach contents difference between length classification. Also, determined some independent population which different length group, has no overlap from feed aspect.
