No abstracts are to be cited without prior reference to the author.The distribution of the European eel, Anguilla anguilla (Linnaeus, 1758), includes the Mediterranean and the Atlantic coasts of Europe and North Africa, from Scandinavia to Mauritania. The Lusitanian toadfish, Halobatrachus didactylus (Bloch & Schneider, 1801), is a benthic voracious fish with a distribution ranging from Cabo Carvoeiro (centre of Portugal) to the Gulf of Guinea. Although this subtropical fish is primarily a marine species, in the northern range of its distribution area (southwest of Portugal), due to reproductive thermal constraints in the sea, it colonizes mostly brackish water systems where it becomes dominant. Therefore, in the southwest of Portugal both species occur in sympatry in estuaries and open coastal lagoons. The aim of this work was to analyse the ecological consequences of such sympatry considering the Mira estuary as a case study. Both species showed similar habits and a high diet overlap. Moreover, the ...
