Most of the cod and haddock we eat comes from the seas around the Arctic, where rapidly- receding sea ice means an entire new ocean is being uncovered.
Environmentalists are concerned that, despite a voluntary moratorium protecting pristine Arctic waters, irreparable damage could be done by fishing trawlers.
But Arctic fishermen argue that as the fish move north with increasing sea temperatures they should be allowed to follow them, as long as they fish responsibly.
