This study has aimed to determine the food regime of Nemipterus japonicus in Bushehr province water, between Bushehr and Nyband using the vacant stomach index (VI), food behavior index (FB) and gonado-somatic index (GSI) in 2012-2013. 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.
