Sergi Tudela, head of fisheries at WWF Mediterranean said: “After overwhelming scientific justification and growing political support in past months – with backing from the majority of catch quota holders on both sides of the Atlantic – it is scandalous that governments did not even get the chance to engage in meaningful debate about the international trade ban proposal for Atlantic bluefin tuna.

“The regional fisheries management organization in charge of this fishery - ICCAT - has repeatedly failed to sustainable manage this fishery. ICCAT has so far failed miserably in this duty so every pressure at the highest level must come to bear to ensure it does what it should.”

WWF said it would call on restaurants, retailers, chefs and consumers around the world to stop selling, serving, buying and eating bluefin.

“It is now more important than ever for people to do what the politicians failed to do – stop consuming bluefin tuna,” Dr Tudela said.
