The integration of survey data in the processes of the Regional Fisheries Management Organisations is a key step for conservation of deep-sea ecosystems and sustainable exploitation of deep-sea fisheries resources, including the mitigation of by-catch and discards of cold-water corals and deep-sea sponges, both considered by FAO as vulnerable marine ecosystems (VMEs) indicator species. Information on corals and sponges from annual bottom trawl groundfish surveys in areas beyond national jurisdictions has been integrated into the “ecosystem management cycle” of the Northwest Atlantic Fisheries Organization (NAFO). Survey data have improved our knowledge on VMEs identification, distribution and extent, and has led to the proposal and implementation of conservation and management measures. These data have particular relevance to delineate and refine the boundaries of areas closed to commercial bottom fishing (14 closures), in order to prevent significant adverse impacts on VMEs, according to the mandate of United Nations General Assembly Resolution 61/105. Considering the European groundfish surveys in the NAFO Regulatory Area (high seas) as a case study, the paper presents an overview of how invertebrate catch data have been integrated into the fisheries management process as a basis to the implementation of VMEs closed areas. Fishing closures are considered effective spatial management measures to avoid by-catch and discards of cold-water corals and deep-sea sponges in commercial bottom fishing, mitigating the adverse impacts on deep-sea ecosystems Versión del editor 1,865
