High-End Restaurant, Nobu, Is Serving Overfished Bluefin Tuna

Greenpeace has accused Nobu, the swank sushi chain, of serving overfished bluefin tuna. Greenpeace investigators purchased tuna at Nobu’s three London locations, and DNA tests showed that it is northern bluefin tuna, Thunnus thynnus, a species that has been subject to rampant illegal fishing in the Mediterranean and eastern Atlantic for the past 15 years as sushi has become more popular. The chain, co-owned by Robert DeNiro and with restaurants in New York, London, and other cities, is often frequented by A-list celebrities. Other well-known chefs, such as Gordon Ramsey, have stopped serving bluefin tuna. Greenpeace has called on Nobu’s founder, Nobu Matsuhisa, to ban the fish in his restaurants.
