According to Intrafish on January 3, the traditional British dish of fish and chips could be replaced by squid. Warmer waters off the coast of Britain are favourable for squid and other fish such as sardines and anchovies in the North Sea. Squid now make up 60% of the North Sea's population, up from 20% in the 1980s.

John Pinnegar, a Marine climate change expert at the UK's Centre for Environment, Fisheries and Farming Science, said the UK's coastal waters would continue to warm by 2025. British fishermen are catching different species today. 20 or 30 years ago, it would have been impossible to catch squid. Britain plans to increase its squid export trade.

In the summer, squid fishing is concentrated in Monray Firth in North-East Scotland, where efforts have been made to reduce overfishing, particularly of traditional fish such as haddock and loke. As temperatures rose, the cod moved north towards Norway, while the plaice moved closer to Scotland from the Netherlands.
