Facilities

Research permits in aquaculture

Large scale, commercially beneficial research is being carried out together with the fish farming industry in Southern, Central and Northern Norway as part of Nofima’s research licenses.

Fish Pilot Plant

The fish pilot plant has its own fish reception area where whole fish and fillets are delivered to undergo quality analysis.

Tromsø Aquaculture Research Station

Tromsø Aquaculture Research Station, of which we are part-owners, is a modern research facility for experimental studies of marine fish, freshwater fish, molluscs, crustaceans and other aquatic organisms.

Nofima Centre for Recirculation in Aquaculture

Recirculation of water provides extremely good control of the water environment, sensible utilisation of water sources and better protection against infection.

Research Station for Aquaculture – Sunndalsøra

At this land-based research station at Sunndalsøra with fresh water, seawater and recirculated water, we can carry out biological and technological experiments along the complete aquaculture value chain.
