Mitsubishi's acquisition of Cermaq has brought the Norway-based multinational salmon producer "massive" benefits, particularly in the areas of investment and research and development.

That's the view of Steven Rafferty, who recently became the global group's CEO, moving from his position overseeing operations in Chile.

Mitsubishi, a sprawling Japanese conglomerate perhaps best known for its automobiles, acquired Cermaq in 2014 in a deal that valued the company at well over $1 billion.

Unlike rival publicly traded salmon farmers that often look quarter to quarter, Cermaq has the advantage now of being part of a company that thinks long term; the roots of today's Mitsubishi corporation stretch back 150 years.
