Facilities

Tromsø Aquaculture Research Station

The Aquaculture Research Station, of which we are part-owners, provides experimental facilities suitable for all types of experiment on fish and shellfish.

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 Sustainable Aquaculture

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.
