(2004) Osservazioni sul regime alimentare di Diplodus annularis (Linnaeus, 1758) nello stagno di Calich (Sardegna nord occidentale) = Observations on the feeding behaviour of Diplodus annularis (Linnaeus, 1758) in the Calich Lagoon (North Western Sardinia).

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.
