Nobu restaurants in London have been selling endangered tuna, undercover investigators have discovered. Investigators ordered tuna from three Nobu restaurants described only by Japanese terms for the cut of the fish they were from. When samples were tested they were found to be Atlantic bluefin which the International Union for the Conservation of Nature’s Red List lists as critically endangered. The Sunday Telegraph says Nobu is not doing anything illegal but many chefs have chosen not to serve Atlantic bluefin because of fears that fishing is at higher levels than stocks can withstand. However, the newspaper says the lack of clear information about the species on sale could land Nobu in trouble with trading standards officers. Nobu declined to comment.
