| Resumo: | The feeding habits of the sparid Diplodus annularis (L., 1758) from two Posidonia oceanica (L.) Delile, 1813 seagrass beds off Murcia (western Mediterranean), were analysed to determinate seasonal changes. Stomach contents of 289 specimens collected during experimental trawling from August 1993 to May 1994, were analysed. Diet varied seasonally: at Mazarron site, apendicularians and amphipods were more important in autumn, whereas during winter and spring amphipods were more important. At Cape Palos, Posidonia oceanica and algae were more important in summer, algae and hydrozoa in autumn, algae and briozoa in winter and harpacticoid copepods and gammarid amphipods in spring. The results indicate that Diplodus annularis feeds on a wide range of prey items, and could be considered a generalist feeder. |
