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.

Together, the seven most commercially important tuna species are among the most economically valuable fishon the planet. Globally, commercially landed tuna product has a value of US$10 billion to $12 billion per year tothe fishermen that target tunas and more than US$42 billion per year at the final point of sale. These conservativetotals do not account for noncommercial values of tuna, including... Read More
What happens to dwindling marine populations, such as Pacific bluefin tuna, when international fishery managers fail to follow best practices and clear scientific advice several years in a row? We may soon find out in the eastern Pacific Ocean. Read More
Harvest control rules (HCRs) are the operational component of a harvest strategy, essentially pre-agreed guidelines that determine how much fishing can take place, based on indicators of the targeted stock’s status. These indicators can be based on either monitoring data or models. Read More
