ABSTRACT: Mangrove is a detritus producer in many coastal ecosystems. Mangrove detritus is used by marine organisms as one of their main food sources. Mullet, a detrivorous fish, is known to feed on mangrove detritus as their primary food source. The research was carried out for 6 months (Mei 2010- October 2010) in a mangrove area on the north coast of South Konawe Regency, Southeast Sulawesi. Fish samples were collected using gill net. Based on the analysis of stomach contents, the diets of mullet fish can be classified into six types which were detritus, algae, diatom, foraminifera, copepods and mollusks. Detritus group was the main diet component constituted for 43.29% to 48.29% of the total food components. It was estimated that the total enegy of detritus component found in the fish stomach ranged from 0.99 kkal/g to 1.03 kkal/g
