English: The Aveiro lagoon (Ria de Aveiro) in Portugal is a coastal wetland that comprises beaches, dunes, mudflats, salt marshes, seagrasses and small water channels. Due to its rich biodiversity and role in hosting numerous invaluable habitats, the impressive natural capital of the Aveiro lagoon has had it classified as a Natura 2000 site, with a designation as a Special Protection Zone and a Site of Community Importance under the EU Birds and Habitats Directives. The Aveiro lagoon is also part of the European Fisheries Areas Network (FARNET) and it maintains sustainable development practices for fisheries and coastal areas through the activities of the Aveiro Fisheries Local Action Group — a partnership between fisheries actors and other private and public stakeholders.
