Detailed Description

Salmon forms the lifeblood for many in Alaska. The state hosts all five Pacific salmon species; Alaskan salmon hold cultural, economic and ecological significance. One of the major climate factors affecting salmon in Alaska is the increasing occurrence of extreme heat events. A record-breaking heatwave and drought in 2019 caused stress and unprecedented mortality in Alaskan salmon, affecting adults on their way to spawning grounds. USGS researchers are trying to understand how heatwaves and other climate-driven stressors will affect Alaska’s spawning Pacific salmon into the future. While an event like the 2019 heatwave was devastating—fish that die before spawning don’t contribute to future generations—salmon in Alaska are resilient.
