For centuries, Spanish fishermen have hauled tuna from the sea in the annual "Almadraba" event. But now, thanks to increasing demand from overseas, the tuna numbers are insufficient to sustain the local tradition.
Too much demand for sushi from Japan may finish off stocks of red tuna running dangerously low in the Mediterranean owing to overfishing, say environmentalists from Greenpeace and the World Wildlife Fund (WWF).

"Japan absorbs between 90 and 95 per cent of catches of red tuna and the Mediterranean version is especially appreciated," explains Jose Luis Garcia, head of the WWF oceans section
