Two of Norway's richest men -- Gustav Witzoe and Kjell Inge Rokke -- joined forces to launch one of the more audacious aquaculture projects ever conceived. But the roots of the connection are more personal than business.

The announcement earlier this month that Witzoe's salmon farming group SalMar and Rokke's industrial conglomerate Aker would establish offshore aquaculture company SalMar Aker Ocean took the industry by surprise, with few whispers that the news was coming.

But the relationship between the two men -- whose roots in seafood run deep -- began casually over a Liverpool-Manchester United football match, where TRG and SalMar board member Bjorn Flatgard introduced them

Talk quickly turned to seafood, Rokke said, and it was clear "there was good chemistry between us."
