Artisanal fishing and tourism are the main economic activities in Sada, with the fishing port of Fontán being of the most important points of the municipality. The large volume of sardine catches gives Fontán a leading role in the economic development of this coastal town, where horse mackerel and octopus are other species most present on the menus of the dishes in the area’s restaurants. Shellfish, mainly the clams, is another of the reference products in Sada, which boasts of the groups of shellfish gatherers that extract this bivalve in Praia das Delicias.
