摘要
The feeding habits of 500 specimens of Pagrus pagrus （family： Sparidae）, inhabiting Benghazi Mediterranean Coast, were studied monthly from January to December 2008. The annual diet composition, monthly variations in the diet composition, the variations of diet with length and the intensity of feeding were studied. Pagruspagrus feed on a wide variety of prey types： crustaceans （38.3%）, molluscs （13.2 %）, echinoderms （11.4%）, polychaetes （10.7%）, digestive food （10.3%）, fish parts （7.1%）, seagrasses （6.4%） and sediments （2.7%）. The crustacean was the major food item all year round and it was found in all length groups. In the present study crustaceans, polycheates, seagrasses and sediments decreased as the size increased while molluscs, echinoderms, digestive food and fish parts increased as the fish size increased. The feeding intensity was quite high during the summer and early autumn.
