On Season 6 of The Catch, host Ruxandra Guidi takes a look at one of the world’s most lucrative fish: tuna. The Pacific islands’ tuna fishery makes up more than half of global tuna supply and underpins these developing islands’ economies. But that could change. Climate change is pushing the fishery out of these islands’ waters, onto the high seas, and these island nations risk losing out. On this season, Guidi reports from the Solomon Islands to hear firsthand how the Pacific nations are grappling with these changes.
