Tuna: Learning About the World's Most Valuable Fish

Tuna: Learning About the World's Most Valuable Fish

Tuna species are found throughout the world's oceans and range from large bluefins found in temperate waters and prized on the sushi market to small, tropical skipjacks, which are destined for canning. As a group, the major tuna species are caught, traded, and consumed worldwide at a pace of about 4 million tons a year.

Some populations of yellowfin, bigeye, and albacore tuna are overexploited, and all three bluefin species are overfished—some populations severely so. Pew sponsors biological and economic research that informs the management of these important and wide-ranging fish.

Data-driven policymaking is not just a tool for finding new solutions for emerging challenges, it makes government more effective and better able to serve the public interest. In the coming months, President Joe Biden and the 117th Congress will tackle a number of environmental, health, public safety, and fiscal and economic issues—nearly all of them complicated by the COVID-19 pandemic. To help solve specific, systemic problems in a nonpartisan fashion, Pew has compiled a series of briefings and recommendations based on our research, technical assistance, and advocacy work across America.
