Crew members on the Nakajomaru katsuo (skipjack tuna) fishing boat catch katsuo using traditional ipponzuri (single pole fishing method), in Tosa Bay, Kochi Prefecture, Japan, May 15, 2022. Locals and experts say fatty katsuo indicates climate change and a risk for the fish numbers already under threat due to growing demand and overfishing. It "must have something to do with the water temperature," captain Takeo Nakajo, 70, said. "I have a sense of urgency thinking what if katsuo doesn't come to the bay some day."
