Under the leadership of Fraunhofer EMB in Lübeck, new technologies for aquaculture are being developed in order to make the operation of aquaculture more energy-efficient, sustainable, economic and profitable. Fraunhofer EMB is supported by several Schleswig-Holstein companies from the entire value chain of the aquaculture industry and other Fraunhhofer institutes with expertise in the field of aquaculture from northern Germany. The new technologies should thus be implemented as comprehensively as possible and contribute to a structural change away from declining and increasingly unprofitable fishing to fish farming.
