Working to improve international agreements to protect bluefin tuna and to take effective action in work for global tuna conservation.
Ranging far and wide across the oceans, tuna are found throughout the world, generally in tropical and temperate waters. Not only are these fish commercially important—they are also critical to the well-being of our oceans and the millions of people who depend on the greater marine ecosystem for food and economic stability.
Unfortunately, many populations are in decline —making the need for sustainable global tuna fisheries clearer than ever before.
The huge demand for tuna—as a popular ingredient in sushi and tuna steaks, and as mass produced, affordable canned fish across much of Europe, Asia, and the United States—has resulted in overfishing and mismanagement of many tuna species. Destructive fishing practices endanger not only the health of fish stocks, but also the livelihoods of approximately 450 million people—and the food security of some three billion people.
Pew is working to improve the international management of tuna species by
- promoting science-based catch limits that do not allow overfishing;
- minimizing the impacts of destructive fishing gears;
- eliminating illegal, unreported, and unregulated (IUU) fishing;
- increasing the transparency and accountability of tuna regional fisheries management organizations.

Implementing an electronic system for tracking the trade in Atlantic bluefin tuna hasn’t been easy. Technical and political issues delayed the launch four times in as many years. But with the recovery of this iconic species on the line, governments involved in the fishery are showing a new urgency for bringing the system fully online and making it mandatory. Read More
Years of overfishing have left the Pacific bluefin tuna population at just 4 percent of its original size, and catchlimits are still set above scientifically recommended levels. Read More
Pacific bluefin tuna caught a break in 2014, but recent steps to prevent further population declines may not be enough. Although fishing nations agreed to measures that cut the bluefin catch this year, new research indicates that this majestic fish needs more help. Read More
