Only about one in eight UK fisheries have been awarded “green” status for sustainability in the latest edition of the Good Fish Guide.

Of the 337 wild fisheries around the British Isles included on the list, which is compiled by the Marine Conservation Society (MCS) and updated twice a year, only 13% were regarded as good sustainable choices. The MCS categorises a fishery as a species of fish or shellfish from a specific area caught in a specific way.
