Impact of Warming Rivers on Salmon in Alaska and Yukon
Researchers from the Institute of Arctic and Alpine Research at the University of Colorado Boulder have incorporated Indigenous knowledge into their study on the effects of climate change on rivers in Alaska and Yukon.
The study found that the North, including the Yukon and Alaska, is warming at a faster rate than the rest of the world, which may affect baby salmon hatching in rivers.
- Porcupine River
- Teedriinjik River
- Aniak River
- Andreafsky River
- Koyukuk River
- Takotna River
- Chena River
The warming of the Porcupine River may limit the growth of Chinook salmon, as the frequency of days and river length are expected to warm to the upper limit of the temperature range for individual growth.
Salmon hatch inland in freshwater and migrate out to sea, returning inland as adults to spawn and then die.
The Porcupine River connects to the Yukon River at Fort Yukon in Alaska and flows out to the Bering Sea.
