Four pilot studies under the EU-funded TETRAS project are exploring innovative ways to make recirculating aquaculture systems (RAS) more sustainable and circular.
In Denmark, Business Lolland-Falster is testing methods to clean and reuse saltwater from land-based fish farms, achieving drinking water quality and exploring industrial reuse opportunities. Meanwhile, Guldborgsund Municipality focuses on raising awareness of RAS and introducing African catfish (Clarias gariepinus) to Danish consumers through education and tasting events.
The project promotes industrial symbiosis, connecting aquaculture with other industries to reuse water and nutrient sidestreams, turning waste into new value.
As explained by Freya Robinson (Submariner Network) and Erika Zavackienė (Klaipėda Science and Technology Park), TETRAS links research, business, and policy to support the circular blue economy and develop business models for sustainable aquaculture across the Baltic Sea region.
