The CEO of salmon farming giant Cermaq remains skeptical of large-scale, land-based salmon production before the process becomes technologically and biologically robust.

"That doesn't mean land-based aquaculture is not interesting," Geir Molvik told IntraFish. "We already produce a lot of large smolt and raise broodfish up to 1 kilogram on land."

But what still needs to be explored is whether land-based salmon can pivot into a profitable business, he said.
