Japanese consumers are being urged to stop eating endangered bluefin tuna after a celebrity chef with restaurants in Japan decided to take it off all his menus.

Gordon Ramsay, who has two restaurants at the Conrad Tokyo hotel, has removed the endangered fish from the menus of all of his outlets worldwide following pressure from the Marine Conservation Society.

Over the last few years in Britain, several restaurants specializing in Japanese cuisine have taken bluefin tuna off their menus amid growing concern over dwindling stocks due to overfishing.

Bluefin is coveted for sushi and sashimi and around 80 percent of the world's stocks are consumed in Japan.
