It’s the go-to meal for a visit to the seaside, but cod and chips could soon be off the menu, according to a new study. Researchers from Rutgers University have warned that rising sea temperatures will mean fewer popular fish species will be available to catch over the next 200 years. ‘While the species we fish today will be there tomorrow, they will not be there in the same abundance,’ warned Dr Malin Pinsky, co-author of the study. Experts from Aberdeen analysed 30 years of trawl survey data on cod, haddock, whiting and saith from the International Council for the Exploration of the Sea. They found that while juvenile fish in the North Sea and the West of Scotland have been getting bigger, the size of adults has been decreasing.
