The government decided in August 2001 to establish a cod breeding programme, and Nofima (former Fiskeriforskning) got the task of carrying out the practical portion.

Production at the Norwegian Cod Breeding Centre takes place in two steps. Fry production is done in a land facility where seawater is pumped into the tanks, while further growth takes place in cages in the sea.

The land facility

The land facility is located at Kraknes on Kvaløya outside Tromsø. Here, the parent cod are stripped of roe and milt, and the cod fry are hatched and fed up until they are ready to be transferred to the sea. The number of tanks, tank size, water requirements and water treatment are adapted for a production of 200 family groups.

The marine farm

When the cod is ready to be transferred to the sea, it is moved to the marine farm in Røsneshamn on Ringvassøy outside Kvaløya, where it is kept until it is sexually mature. The best individuals are then transported back to the land facility at Kraknes to be parents for new generations.

The marine farm has equipment to measure, weigh, mark and vaccinate the cod. It consists of 12 steel cages and an integrated service raft. The cages have seine bags with extra strong thread to reduce the danger of escape. The cages also have shadow nets to prevent the cod from getting sunburned. Dead fish, excrement and feed remains are taken up with the help of a lift-up system. Dead fish are collected in a separate dead fish tank, where they are ensiled (acid is added), while the rest of the waste is led away through pipes.

The fish are fed with the help of an appetite-controlled feeding system with recirculation of uneaten feed. The service raft is 35 x 15 metres with a building that houses a wet laboratory, feed storage, net storage, workshop, store rooms, office, lounge with kitchen, bathroom, dressing room and bedroom.
History

During the first half of 2002, the strategy for establishing the breeding centre was laid and it would be built in connection with Tromsø Aquaculture Research Station in Kårvik on Ringvassøy.

In the spring of 2003, there was an offer by Troms Marin Yngel to buy their newly built cod hatchery at Kraknes on Kvaløya. This facility would be well suited as a breeding centre.
After a relatively modest rebuilding, the Norwegian Cod Breeding Centre was officially opened on 19 August, 2005 by Minister of Fisheries and Coastal Affairs, Svein Ludvigsen.
