The British still love their fish and chips, and for most it has to be cod or haddock. But warming seas might mean the cod-hungry Brits might have to widen their culinary horizons. In future, they may have to accept that a trip to the local “Chippie” will see them choosing from the less popular species. Who’s for John Dory, sardines, red mullet, maybe gurnard, cuttlefish, squid or even anchovies?
Along with cod and haddock, other popular North Sea fish like plaice and lemon sole could become less common as ocean warming restricts their preferred habitat.
The warnings come in a study published in the journal Nature Climate Change.
Fish distributions are limited by water temperature and some species can only thrive in certain habitats and depths. In the last 40 years the North Sea has warmed four times faster than the global average and further warming is predicted over the coming century.
