The sampling of fishes and Macrobenthic were performed in Goharbaran Mazandaran province by selecting four stations at a depth of 5 meters and four stations at a depth of 10 meters a monthly basis from May 2013 to April 2014 and fish samples of coastal blade caught were used. During the study, a total of 565902 Macrobenthic invertebrates isolates belonging to 22 species of 9 families. Oligochaeta worms were identified at the level of the class and Polychaeta worms including 5 genera and species were. Crustacea with 16 species had the highest number of species than other species. Among the 6 species of fish, Rutilus kutum and Liza aurata were 73.05% and 24.67% of the total catch, respectively.The present study showed that Bivalvia, especially Cerastorderma, have a high relative importance for Rutilus kutum and the importance of Gastropoda, Crabs, Fish eggs, Filamentous alge was rare for this species. Also the most feeding of Cyprinus carpio, Liza auratus, and Liza saliens species were from Detrite. After Detrite, the most important food items for Cyprinus carpio were Bivalvia, Abra ovata, Gastropoda, Oligochaeta, Nereis, Fish eggs, Filamentous alge. After Detrite, the most important food items for Liza auratus were Foraminifera, Porifera and Balanus and for Liza saliens were related to Gastropoda, Bivalvia and Porifera. Due to the combination of  Macrobenthic invertebrates and the reduction of Bivalvia in the Goharbaran region, bait Food is not enough for the Rutilus kutum stocks. The present study showed that Bivalvia, especially Cerastorderma, have a high relative importance Rutilus kutum. The relative importance of Bivalvia in feeding carp was far more than other foods. In Ditritus, Mugillidae of fish in the present study was consistent with the results of other studies.
Keywords: Macrobenthic invertebrates, Feeding, Rutilus kutum, Cyprinus carpio, Mugillidae, Goharbaran.
