Sustainable Fisheries Partnership Agreements (SFPAs) aim to create a partnership to promote sustainable fisheries, based on the best available scientific advice. Therefore, a Joint Scientific Committee (JSC) of highly qualified scientific experts needs to be established in each SFPA, assuring that management measures are based on the best scientific advice available.
The European Commission has today adopted a key investment package for the Latvian fisheries and aquaculture sector worth almost €184m, including €139m of EU investments.
