Following a recommendation made last September by The International Council for the Exploration of the Sea (ICES), Waitrose has now suspended its mackerel supply.
Upon scientific advice, ICES had advised that there needed to be a 70% reduction in North-east Atlantic mackerel catches due to overfishing.
Four Coastal States agreed to cut catches by 48% in December 2025, but this obviously still fell short of the guidance.
From May 2026, North East Atlantic mackerel, which Waitrose sources from Scottish Waters, will no longer meet their responsible sourcing requirements under the Sustainable Seafood Coalition’s (SSC) codes of conduct.
Fresh, chilled and frozen mackerel will be removed from shelves by 29th April 2026, whilst remaining tinned stock will continue until existing inventory is depleted.
To support customers through the transition, Waitrose is introducing a new range of smoked fish from April 2026.
The new product range will consist of:
- Waitrose Scottish Hot Smoked Herring (Marine Stewardship Council (MSC) certified)
- Waitrose Scottish Hot Smoked Peppered Herring (MSC certified)
- Waitrose Hot Smoked Sweetcure Seabass (Aquaculture Stewardship Council (ASC) certified)
- Waitrose Hot Smoked Trout with Dill & Lemon (Royal Society for the Prevention of Cruelty to Animals (RSPCA) assured)
- Waitrose Frozen Sardine Fillets (MSC certified). (From May 2026)
Waitrose has stated that it will continue supporting British coastal communities by preserving long-term relationships with mackerel suppliers, although no specific date for resuming sourcing has been confirmed.
Existing partnerships will continue supplying herring, seabass, sardines and trout.
