In this study, fish remains that were taken from the final levels attributed to the Gumelnița culture within the tell-settlement at Luncavița were analyzed. The remains from waste deposits/areas were primarily taken into account. This selection, based on a reliable stratigraphic and chronological classification, allowed us to create, in addition to comparisons, an overview of the fish consumption at the end of the site's inhabitation. Thus, the identified species are present in the Danube and its floodable areas – sturgeon, carp, wels catfish, pike and pikeperch, common bream, asp, tench, roach and common rudd. Fishing took place in the Danube and its branches, especially during the summer. Part of the fish was brought whole to the site and prepared for consumption. The approximate quantity for the researched areas is about 5 tons, catfish having the biggest contribution. The exploitation of aquatic resources proved an important activity for the inhabitants of Luncavița «Cetățuia» that provided, at least during the summer, a source of protein complementary to that obtained from hunting or animal husbandry.
