A new report has found that UK retailers are selling canned tuna that is caught using destructive fishing methods. The report, titled "The UK's Tuna Blind Spot," conducted by the Blue Marine Foundation in collaboration with BLOOM Association and Greenpeace UK, found significant disparities between the sourcing policies of UK retailers' own-label canned tuna and the brand-name tuna they sell. Only one out of the top ten supermarkets, Marks & Spencer, was able to demonstrate that none of the canned tuna it sold was caught using harmful fishing methods.
The report highlighted that several other retailers, including Co-op, Waitrose, Sainsbury's, and Morrisons, have policies against the use of harmful fishing methods for their own-label products but continue to sell brand-name tuna that is sourced from fleets using destructive fishing techniques. The report also criticized Iceland, which only sells brand-name tuna sourced from fleets that use fishing methods that harm marine habitats. The report called on UK retailers to stop selling tuna caught with destructive fishing methods in the Indian Ocean and to extend their sourcing policies to cover brand-name products.
