Mowi, the world's largest salmon farmer, is reconsidering its involvement in land-based salmon farming only a year after dismissing the sector.

"We are looking at all possibilities," CEO Ivan Vindheim told IntraFish's sister publication DN. "We are the largest player in salmon production and we intend to remain so. Everything we see that can be profitable, we will do."

Traditional netpen salmon farmers have been reluctant to move into land-based salmon farming.
