There is a growing trend towards mergers and acquisitions (M&A) as well as stock listings in the salmon sector, which is unlikely to abate any time soon despite certain hurdles, according to senior figures at the Norwegian brokerage Pareto Securities.

"More salmon companies will be acquired; there is great interest out there," Carl-Emil Kjolas Johannessen, an equity analyst at Pareto, told IntraFish.

But acquisitions won't be without their challenges.

"Most companies have a large majority owner who sits in the driver's seat," he said.
