With marine heat waves helping to wipe out some of Alaska’s storied salmon runs in recent years, officials have resorted to sending emergency food shipments to affected communities while scientists warn that the industry’s days of traditional harvests may be numbered.
Salmon all but disappeared from the 2,000-mile (3,200-km) Yukon River run last year, as record-high temperatures led to the fish piling up dead in streams and rivers before they were able to spawn. A study published Feb. 15 in the journal Fisheries detailed more than 100 salmon die-offs at freshwater sites around Alaska.
