Facilities

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.
