North Sea cod is to lose its sustainability certification due to concerns about stock levels.
The Marine Stewardship Council said certificates for North Sea cod fisheries would be suspended as stocks were below the “safe biological level”.
A “blue tick” had been awarded in 2017, meaning cod could be eaten “with a clear conscience”.
The Marine Stewardship Council (MSC) said the suspension was “devastating” but that stock levels were “worrying”.
The Scottish government said the loss of accreditation for cod stocks was “very disappointing”.
The fish had been considered under threat for more than a decade after stocks were said to have fallen to about 40,000 tonnes in 2006.
The industry agreed measures to help regenerate the population, including new nets and closing spawning areas to fishing.
However in June, the International Council for the Exploration of the Sea (Ices) warned cod was being “harvested unsustainably”.
