(The Local) The billionaire founder of Marine Harvest, the Norwegian salmon farming giant, has revealed plans to convert his surplus cargo vessels into floating fish farms.

“We look at other opportunities and have several times considered starting production on board ships,” John Fredriksen, the shipping tycoon, told DN newspaper as he listed the fish-farming company on the New York Stock Exhange on Tuesday. “Ships are something that we have plenty of, let’s put it that way.”

The company’s shares rose ten percent on their first day of trading on the New York Stock Exchange on Tuesday.
