Like so many Norwegians, Renate Larsen was born with fish in her blood. But her skill and ambition over a 19-year career in the industry was unique -- it drove her to the top of the world's largest seafood marketing organization.

As CEO of the Norwegian Seafood Council (NSC), she's already seen a difference in the gender make-up compared with her previous roles, which include being CEO of Leroy Aurora.

"I've grown used to being the only woman in the meeting, the only woman at the work dinner, but now that I'm working with the market, I'm not the only woman anymore," Larsen said.
