Tesco, Sainsbury’s, Asda, M&S, Morrisons and Co-op join major seafood brands and WWF in campaign to stop Indian Ocean fish stocks collapsing

Major European seafood brands and the UK’s largest supermarkets – including Tesco, Sainsbury’s, Asda, Marks & Spencer, Morrisons and the Co-op – are backing a call to cut yellowfin tuna catches in the Indian Ocean to stop stocks collapsing.

The companies, along with WWF, are urging the Indian Ocean Tuna Commission (IOTC) to reduce catches by 20% and introduce harvest control rules to ensure the sustainability of all Indian Ocean tuna stocks, including skipjack.
