A total of 544 fish specimens of the golden grey mullet Liza aurata (Risso, 1810) were random sampled monthly during the period from September 2019 to August 2020. They were obtained from fish landing site at Bitter Lakes. The diet composition of L. aurata during the period of study composed of polychaetes (49.9%) supplemented by crustaceans (20.0%), phytoplankton (15.7%), bivalves (11.0%) and sediments (3.5%). polychaetes, crustaceans, phytoplankton and bivalves were found in all months and sediments were disappear in July and August. Polychaetes, crustaceans and bivalves decreased as the fish size increased while, phytoplankton and sediments increased as the fish size increased. In the present study the feeding activities for Liza aurata were quite high during spring (72.3%) and summer (58.3%). were minimal rate of feeding intensity in autumn (33.1%) and winter (41.7%).
