The World Wide Fund for Nature and Greenpeace have run separate campaigns against the unregulated fishery, which is dominated by Denmark and Norway.
The organisations argue that the huge catches jeopardise the entire ecosystem because they take small fish near the base of the food chain. Sainsbury, Unilever, Associated British Foods and McVities have already promised to pull out of North Sea fish oil. Britain imports 260,000 tonnes a year, mostly for use in margarines.
