sushinho's decision comes in the wake of the EU nations' recent decision to support a ban on international trade in Atlantic bluefin tuna until stocks recover. Last year, scientists reported that the bluefin's decline had been so extreme that a trade ban was in order. They calculated that the stock is now at approximately 15% of the level it was at in the era before industrial fishing began. Meanwhile, yellowfin tuna — although less endangered than bluefin — is still over fished, and will likely suffer all the more as a consequence of bluefin being banned. sushinho's owner Oliver Girardet explains more about the decision: "With half of the fish eaten in Europe dished up in restaurants, it is time that restaurants such as sushinho took the lead and stopped demand at source. We owe it not only to this generation, but to generations to come." Should global tuna stock return to a healthy level, or a source be found from which sushinho can obtain sustainable and responsibly caught tuna, the restaurant will then consider putting tuna back on the menu.
