Abstract (EN): Eels (136-627 mm TL) fed on prey organisms ranging from 2.0-76.0 mm in length. Amphipods and shore crab Carcinus maenas were the most important food items. In more saline muddy bottom areas polychaetes, bivalves and shrimp increased their importance as prey, replacing the amphipods as preferential food. Fish were always a secondary although significant, prey item. Seasonal variations in eels' diet could be attributed to fluctuations in prey densities. There was evidence of a close relationship between quantity of prey organisms in the benthos and the composition of eels' stomach contents, but a certain degree of food selection based on size, concealment capacity and motility of prey, was found. -from Authors
