BioPradaRia aims to contribute to enhancing the protection and restoration of aquatic biodiversity and aquatic ecosystems within the framework of sustainable fishing activities, particularly for a better management or conservation of marine biological resources, having Ria de Aveiro as a case study. In the proposed approach, which combines knowledge of role-players and stakeholders with ‘scientific knowledge’, ‘lessons learned’ will be compiled into a road map for restoration, management and conservation of biodiversity and biological resources associated with Ria de Aveiro seagrass ecosystems. The BioPradaRia project will test fixed devices to protect seagrasses and thereby revitalize the associated fauna (including fish fauna), as well as testing for the replacement of bivalve fishing gear with other low impact gear. The road map produced can serve as a basis for the Protection and Restoration of Biodiversity and Marine Ecosystems in other national coastal ecosystems, as well as supporting awareness and training on the management or conservation of marine biological resources.
