It took CEO Alf Helge Aarskog just a decade to bring Mowi -- then called Marine Harvest -- from a market cap of NOK 22 billion (€2.1 billion/$2.4 billion) in 2010 to NOK 118 billion (€11.7 billion/$12.8 billion) today, a journey that created the world's most valuable seafood company.

The CEO stepped down on Nov. 12, replaced by Mowi's current CFO Ivan Vindheim.

Aarskog oversaw a remarkable period of growth and development and led ambitious projects, including creating Mowi's own fish feed operations, massively growing the company's value-added processing division, growing farming volumes substantially and, most recently, launching the company's new branding strategy.

From one CEO chair to another

Aarskog's journey started in July 2010, when Mowi poached him from Leroy Seafood after being in the top role at that firm for only four months.
