Feeding behaviour of the annular sea bream Diplodus annularis was investigated in the Calich lagoon (NW Sardinia, Italy). The stomach contents of 130 adult specimens (TL=15.2±1.4 cm) collected in spring and summer 1998 were examined. Benthic fauna such as Mollusca, Amphipoda and Polychaeta were the main food items (23.4%, 18% and 5.7% respectively), but a large amount of detritus was also found (44%).

Abstract
Feeding behaviour of the annular sea bream Diplodus annularis was investigated in the Calich lagoon (NW Sardinia, Italy). The stomach contents of 130 adult specimens (TL=15.2±1.4 cm) collected in spring and summer 1998 were examined. Benthic fauna such as Mollusca, Amphipoda and Polychaeta were the main food items (23.4%, 18% and 5.7% respectively), but a large amount of detritus was also found (44%). Furthermore, significant differences in the diet of smaller and larger size classes were observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
