More than 3 billion people rely on seafood as a primary source of animal protein. But waters are warming, and fish are moving. Are those fish, and the communities that have relied on them for centuries, in trouble?

We go around the world, from the rocky shores of New England to the picturesque island of Niue, to investigate how three popular fish are doing. Along the way, we meet people who are protecting and regrowing these fish populations in different ways and learn about their challenges and successes.

This episode features reporting by Barbara Moran at WBUR, which was produced as part of the Pulitzer Center's StoryReach U.S. Fellowship. Columbia University’s Duy Linh Tu contributed to the reporting.  

Guests: 

Tessa M. Hill, Oceanographer and Professor, Earth and Planetary Sciences, UC Davis

Mona Ainu’u, Minister for the Ministry of Natural Resources, Niue

Jenn Caselle, Research Biologist, Marine Science Institute, UC Santa Barbara
