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.

Every year, hundreds of thousands of pieces of man-made debris are cast adrift on the world’s oceans. This is not random littering; fishermen set the materials afloat to attract fish. These objects, called fish aggregating devices (FADs), are used extensively by purse seine vessels and supporting craft to catch tuna. Read More
The fight to save Pacific bluefin tuna from overfishing—which continues unabated due to inadequate management measures—needs all the support it can get. That’s why Pew never misses an opportunity to remind people that the stock has been depleted by more than 97 percent from unfished levels and that managers have not stopped commercial fleets in the Pacific Ocean from...

In recent years, managers of tuna fisheries around the world have begun to shift to using harvest strategies, or management procedures, because they offer a more predictable and stable approach than the traditional use of stock assessments followed by often contentious quota negotiations. The effectiveness of harvest strategies depends, in large part, on managers first agreeing to... Read More
