Mackerel has long been held up as one of the UK’s most sustainable seafood choices. But from today, fresh, chilled and frozen mackerel has disappeared from Waitrose shelves, after the supermarket said fishing levels were too high to justify continued sales.
The move comes as conservation groups warn that other staples are also under pressure. Earlier this month, the Marine Conservation Society (MCS) downgraded UK-caught cod to its lowest sustainability rating, citing falling populations.
