Species: Oncorhynchus nerka

Pink salmon now comprise nearly 80 percent of all adult salmon in the North Pacific. This record abundance is coming at a cost to other salmon species such as threatened Chinook, which compete with pinks for spawning territory. A new study shows that the ecological toll may extend all the way to endangered southern resident killer whales.

The extensive loss or modification of estuaries throughout Puget Sound creates a significant challenge for adult salmon as they migrate to their natal streams to spawn. A 2024 report by University of Washington scientist Thomas Quinn looks at how different species of salmonids use estuaries to move from marine to freshwater environments. The report was commissioned by the University of Washington Puget Sound Institute with funding from the Environmental Protection Agency's National Estuary Program.

This overview describes the different ways that juvenile Pacific salmon and trout use estuaries, and why those differences are important for ecosystem recovery efforts. The report was commissioned by the University of Washington Puget Sound Institute with funding from the Environmental Protection Agency's National Estuary Program.

The return of sockeye to the Elwha River is intriguing scientists. Could nearby freshwater kokanee help re-establish resident populations? We continue with part four of our series 'Returning home: The Elwha's genetic legacy.' 

Following dam removal, migratory salmon have been free to swim into the upper Elwha River for the first time in 100 years. Their actual behaviors and reproductive success may well be driven by changes in their genetic makeup. Our seven-part series 'Returning home' examines how the fish are doing and whether the Elwha's genetic legacy remains intact. 

Scientists think they may have discovered a lost population of native kokanee salmon in Lake Washington. Salmon watchers are monitoring local creeks this fall to confirm the finding.

Warming waters threaten the recovery of salmon in Puget Sound. New findings about stream temperature could help salmon survive the threats of climate change.

A biennial report produced by the Governor's Salmon Recovery Office provides stories and data about salmon, habitat, and salmon recovery in Washington, including Puget Sound.

Chinook, coho and sockeye salmon, along with steelhead trout, live in the Lake Washington watershed and navigate a treacherous route through the Ballard Locks on their way to Puget Sound.

Researchers updating a 1980 fish catalog have found evidence of 37 additional fish species in the Salish Sea. This information, accompanied by hundreds of detailed illustrations, is seeding a new reference book expected to gain wide use among scientists, anglers and conservationists. [Editor's note: As of 2019, the list of Salish Sea fishes has grown to 260 species.]

This report documents how Washingtonians have responded to the challenges of protecting and restoring salmon and steelhead to healthy status. It also serves as a tool to summarize achievements, track salmon recovery progress through common indicators, and identify data gaps that need to be filled.

Salmon recovery demands both dedication among people with different interests, and sustained resources. This biennial report tells the story of the progress made to date and the challenges ahead.

A 2015 article published in the Marine Ecology Progress Series identifies intraspecific differences in diet between harbor seals in the Salish Sea, suggesting implications for marine reserve management. 

A 2014 report describes a study of socio-cultural values associated with blueback salmon in the Quinault Indian Nation. The blueback salmon (Oncorhynchus nerka) is a unique strain of sockeye that returns primarily to the Quinault river system.

Lead Entities are local organizations in Puget Sound that develop salmon recovery strategies and priorities for the region on a watershed-based scale.
