Diet of poor cod, Trisopterus minutus (Osteichthyes: Gadidae) from the eastern central Adriatic Sea

The diet of poor cod from the central Adriatic Sea was investigated with respect to fish size and seasons. Stomac contents of 1200 specimens, 8.1 to 25.5 cm total length (TL), collected by bottom-trawl from January to December 2006 were analysed. The percentage of empty stomachs varied significantly with seasons (maximum during the winter, 23% ; minimum during the summer, 5%). The prey items identified in the stomachs belong to seven major groups: Decapoda, Mysidacea, Euphausiacea, Stomatopoda, Teleostei, Cephalopoda and Polychaeta. Diet composition showed little seasonal variation ; decapods were the most important prey in all seasons especially during the summer. The lowest intensity of feeding recorded in winter could by related to lower sea temperature and to spwning period. The stomach content of the poor cod indicated that this species could be a euryphagous predator.
