Resumo(s)
The feeding habits of two major species of sole, the common sole Solea vulgaris Quensel, 1806
and the Senegalese sole Solea senegalensis Kaup, 1858 were studied in the lower estuary of the
Guadiana River (Algarve, southern Portugal). An evaluation of the number, weight, and feeding
coefficient of prey types showed that S. vulgaris feed on a limited variety of prey (only Polychaeta
and Tanaidacea) and present low-intensity feeding activity, with small differences in diet between
seasons. S. senegalensis also have a low-diversity diet (with only one more taxa, Amphipoda), but
exhibit more intense feeding activity which varies seasonally, although with little seasonal variation
in the relative importance of the main preys. The diet composition of these two species suggests
feeding specialization.
