What are bluefin tuna?
Bluefin tuna are remarkable, ocean-going fish that grow up to 10 feet long and can weigh 1,200 pounds. Unlike almost all fish, bluefin are warm-blooded and able to regulate their body temperature, which helps during their epic journeys across the ocean. Bluefin tuna are top ocean predators and sometimes hunt cooperatively, much like wolves. With streamlined bodies and retractable fins, bluefin can bolt through the water at speeds of 50 miles per hour and can cross oceans in the course of only a few weeks.
What’s the problem?
Prized as a high-value dish at sushi restaurants, bluefin are being pushed toward extinction by decades of overfishing. The International Union for Conservation of Nature lists two populations of bluefin, the Atlantic and the southern, as critically endangered on its “Red List” of imperiled species. The Pacific bluefin tuna has declined 96.4 percent from unfished levels, according to an assessment released in January 2013. Sadly, bluefin remains on the menu in some restaurants. The sushi market keeps prices for tuna high and encourages illegal and unreported fishing.
What’s being done to help this fish?
As a consumer, how do I know if it’s bluefin tuna?
Are there any types of tuna that are good to eat?
Although the bluefin tuna is one of the most imperiled fish in the sea, other types of marine life also face threats, and reducing fishing pressures can benefit many species. While the Center doesn’t endorse any specific types of seafood, we encourage consumers to consider alternatives to bluefin tuna and stay informed about sustainable eating choices.
These are tough economic times. Instead of boycotting restaurants, why not educate and enlist?
Our campaign is soliciting chefs and restaurant owners to sign the pledge along with consumers. (The restaurant pledge is available at www.bluefinboycott.org.) We welcome our supporters to get firsthand knowledge of restaurants that are serving bluefin and approach them with the pledge, the fact sheet and the Bluefin Boycott logo to post in the restaurant’s windows.
Bluefin is an expensive luxury product, so there will be economic implications of stopping its sale. But fishing a species to extinction has economic implications as well. From 2000 to 2009, gross revenues in the U.S. commercial bluefin tuna fishery declined by 64 percent from 19.1 million to 6.9 million. See table 5 of this pdf for more information.
What science shows that bluefin tuna are in danger of extinction?
Our scientific petition to list the Atlantic bluefin tuna as endangered or threatened explains, in 40 pages, the science that shows Atlantic bluefin tuna are at risk of extinction because of severe overfishing, inadequate regulatory mechanisms, and habitat degradation from the oil spill and climate change.
The International Union for the Conservation of Nature (IUCN) is the world’s foremost international authority on the status of threatened species. The IUCN “Red List” classification system is widely regarded as the most authoritative list of globally threatened species. The IUCN classifies the western Atlantic bluefin tuna population and the southern bluefin tuna as critically endangered, with an extremely high risk of extinction in the wild in the immediate future. IUCN classifies eastern Atlantic bluefin tuna as endangered, meaning that it faces a very high risk of extinction in the wild in the near future. An assessment of Pacific bluefin tuna released in January 2013 estimated a 96.4 percent decline from unfished levels.
How will joining this boycott benefit the species?
Our mission is to reduce consumer demand for imperiled bluefin tuna. Overfishing, including rampant illegal fishing, is the number-one cause of the severe decline of the bluefin tuna. Because regulators have been unable to curb fishing to the extent necessary to sustain a healthy population, this boycott is an effort to save the species from the bottom up.
Japan is by far the primary consumer of bluefin tuna. Nevertheless, in 2009, the United States imported $12.5 million worth of bluefin tuna. Sushi Samba, in Las Vegas, took bluefin tuna off its menu in September and estimates it's saving one tuna a week. Each restaurant that pledges not to serve bluefin makes a difference.
How can we do more than just sign a pledge?
Signing a pledge is just the first step, and an easy click for most people. Next, you can do more:
Can you provide a list of restaurants, distributors, stores and other places that sell bluefin tuna?
For a variety of legal and logistical reasons, we won’t be publishing a list of sushi restaurants selling bluefin tuna or bluefin tuna vendors other than those mentioned in our press release (and we’ll report back if those venues take the pledge). We do have a list of restaurants that have signed our bluefin boycott and a map at www.bluefinboycott.org.
This is a grassroots campaign that relies on you and others like you around the country. We encourage consumers to do research and get firsthand knowledge of other restaurants serving bluefin. Feel free to comment about your experience on the Bluefin Brigade Facebook page.
