The Trump administration rejected a petition Monday to protect imperiled Pacific bluefin tuna under the Endangered Species Act. This powerful apex predator, which commands top prices at fish auctions in Japan, has been overfished to less than 3 percent of its historic population. Although the National Marine Fisheries Service announced in October 2016 that it was considering listing the Pacific bluefin, it has now concluded that protections aren't warranted.

"If the paychecks of fishery managers and federal officials were tied to the status of this marvelous creature, they would have done the right thing," said Carl Safina, president of the Safina Center and a scientist and author who has worked to draw public attention to the plight of the bluefin tuna.

Japan, South Korea, Mexico, the U.S. and other countries have failed to reduce fishing enough to protect this iconic species, a luxury item on sushi menus. One recent study found that bluefin and other large marine organisms are particularly vulnerable to the current mass extinction event; their loss would disrupt the ocean food web in unprecedented ways, and they need more protection to survive.

"Pacific bluefin tuna will spiral toward extinction unless we protect them. The Endangered Species Act works, but not when the Trump administration ignores the plight of animals that need help," said Catherine Kilduff, an attorney with the Center for Biological Diversity. "This disappointing decision makes it even more important for consumers and restaurateurs to boycott bluefin until the species recovers."

In June 2016 petitioners requested that the Fisheries Service protect Pacific bluefin tuna as endangered. The coalition includes the Center for Biological Diversity, The Ocean Foundation, Earthjustice, Center for Food Safety, Defenders of Wildlife, Greenpeace, Mission Blue, Recirculating Farms Coalition, The Safina Center, SandyHook SeaLife Foundation, Sierra Club, Turtle Island Restoration Network and WildEarth Guardians, as well as sustainable-seafood purveyor Jim Chambers.

"The Trump administration's war on the oceans has just launched another hand grenade—one that hastens the extirpation of bluefin tuna from U.S. waters and ultimately hurts fishing communities and our food supply," said Todd Steiner, biologist and executive director of Turtle Island Restoration Network.

Almost all Pacific bluefin tuna harvested today are caught before reproducing, putting in doubt their future as a species. Just a few adult age classes of Pacific bluefin tuna exist, and these will soon disappear due to old age. Without young fish to mature into the spawning stock to replace the aging adults, the future is grim for Pacific bluefin unless immediate steps are taken to halt this decline.

"Instead of celebrating the Pacific bluefin tuna for their impressive and important role in the ocean, humans are sadly fishing them to the brink of extinction in order to put them on the dinner plate," said Brett Garling of Mission Blue. "It's more than regrettable that this gastro-fetish is robbing the ocean of one of its most iconic species. The time is now to wake up and realize that tuna are worth much more swimming in the ocean than in soy sauce on a plate."
