The developers of Norwegian firm Nekst's subsea cage project have put their initial plan to build the world's largest land-based fish farm on hold after struggling to obtain development permits.

This week, investment firm Rofisk bought a 25 percent stake in Nekst for an undisclosed amount. Rofisk is owned by wellboat company Rostein owner Odd Einar Sandoy.

"We are very pleased Rofisk is now joining as co-owner," Nekst General Manager Martin Ramsdal told IntraFish's sister publication DN.
