NOAA Links Chinook Salmon Declines in Yukon River to Bering Sea Heatwaves
In a new study, NOAA scientists at the Alaska Fisheries Science Center have linked the rapid decline of Chinook salmon in the Yukon River to marine heatwaves during 2016–2019, a period when adult run sizes reached their lowest levels on record.
The researchers used a new modeling approach to reconstruct the full Chinook life cycle by combining data from multiple sources: juvenile marine survey data and bycatch information collected by the Alaska Fisheries Science Center, and adult monitoring data collected by the Alaska Department...
