Supermarkets Swap Atlantic Mackerel for Cheaper Jack Mackerel
Some tins labelled mackerel now contain a different fish called Chilean jack mackerel.
Princes has made this change in some products sold through UK supermarkets.
The replacement is cheaper and has less omega-3, an important nutrient found in fish.
Some shoppers have also reported more bones and a metallic smell.
Atlantic mackerel numbers have fallen sharply because too many fish are being caught.
Countries have often disagreed about how much Atlantic mackerel fishing should be allowed.
Supermarkets are changing suppliers to protect fish stocks and keep products available.
However, some shoppers may still pay the same price for the cheaper fish.
People can check the species name on the tin to see which mackerel they are buying.
Princes has replaced Atlantic mackerel with Chilean jack mackerel in some tinned products.
Chilean jack mackerel has roughly half the omega-3 and 100 fewer calories per 100 grams.
Wholesale Chilean jack mackerel reportedly costs about one-third as much as Atlantic mackerel.
Atlantic mackerel stocks have fallen by around three-quarters in the past decade.
Retailers cite supply and sustainability concerns, but shoppers may pay similar prices for the substitute.
