Chinook (or king) salmon are one of our state’s most prized fish, caught by subsistence, commercial, and sport fishermen each summer as the fish return home to Alaska. However, dramatic declines in Chinook salmon populations in recent years have necessitated closures in many Chinook salmon fisheries throughout the State.

Chinook Salmon: One Species at a Time Can painted wooden fish on a schoolyard fence change human behavior and help clean up the ocean for the real salmon? Stream of Dreams in British Columbia thinks so, and a lot of wooden fish and some , school kids later, they have some intriguing results to show for their effort. Recent interest in flood control and restoration strategies in the Chehalis River Basin has increased the need to understand the current status and ecology of spring Chinook salmon. Based on the extended period between freshwater entry and spawn timing, spring Chinook salmon have the longest exposure of all adult Chinook salmon life histories to the low-flow and high water temperature.
