NÄRFISK test bed for RAS technology

Purpose and goal

The project NÄRFISK Test Bed Technology has established a physical and organizational test bed for recycling aquaculture systems (RAS). The physical test bed has been established at Ljusterö in the Stockholm archipelago and was in operation for 21 months during the project, producing 5 tons of pikeperch and perch per year. The project has verified that RAS cultivation of pikeperch and perch is feasible under a variety of conditions and that high quality fish with good taste can be produced.

Results and expected effects

The project NÄRFISK Test Bed Technology has demonstrated that recycling aquaculture systems (RAS) for production of pikeperch and perch works well in a full scale test bed and is feasible to scale up to commercial size. Swedish know-how and equipment companies should be able to benefit from an increasing recycling aquaculture market by taking part in RAS development. Sweden should increase involvement in the development of this technology and in eco-cycle oriented urban food supply.

Approach and implementation

The project NÄRFISK Test Bed Technology was carried out with the company Ecoloop AB as project owner and with participation from KTH, Chalmers and the companies Svensk Fiskodling AB, Wallenius Water AB and Nordic Water AB. The consortium rented a RAS owned by Svensk Fiskodling AB and further developed it to a test bed. During the project, the Wallenius Water AOT technology and the Nordic Water Dynasand technology have been tested. Improved monitoring and control of RAS have also been tested.
