In this study, the diet of S. megalops and S. blainvillei in the Gulf of Gabes (Central Mediterranean Sea) was investigated between 2007 and 2009, by collecting monthly samples of these two species from local fishing vessels. In the stomachs of both species, teleosts were the dominant prey items, and crustaceans, molluscs, and annelids, were found in lower abundance. A three-factor multivariate analysis of variance (MANOVA) demonstrated significant differences in diet related to size, season and sex in S. megalops but not related to size in S. blainvillei.
