Farmed halibut

01.01.2014 // Halibut farming started in the beginning of the 1980s, but difficulties with fry production gave the industry a difficult start. Today there is a small commercial production of halibut in Norway. In 2012 Norwegian farmers produced 1 741 tonnes of halibut.

It is only in recent years that sufficient knowledge concerning the technology and biology associated with halibut farming has been acquired to render profitable production possible.   

Larvae are dependent on live feed

In halibut farming, all phases of production require special solutions compared to farming of other species such as salmon. The larvae of the halibut are very fragile and hence there are stringent demands in regard to hygiene and gentle handling during production. As with cod larvae, halibut larvae are dependent on live feed after the yolk sac phase. Ensuring that the live prey contains the right nutrients has represented a big challenge in halibut farming.

The grown halibut is a good hunter and a brilliant swimmer. When farming halibut, it is important to present the feed pellets in such a way that the hunter instinct of halibut is triggered, as halibut will seldom eat pellets that have sunk to the bottom. Halibut is a flatfish and needs flat areas where it can rest between feeding. To increase the resting area, many farmers now build shelves in the cages.
