FishSalmon and other anadromous fish

The Snake and its tributary, the Salmon River, host the longest sockeye salmon run in the world, stretching 900 miles from the Pacific to Redfish Lake in Idaho. Dams and other human activity have greatly reduced the runs since the late 1800s.

Listed fish are the species named for the river on its Wikipedia page. Check the Idaho Department of Fish and Game for river-specific regulations before you fish.
