Salmonids

Fish in the family Salmonidae (salmon, trout, and charr) are unique in their cultural, economic and ecological role in Puget Sound. Because they utilize a very wide range of aquatic habitat types throughout their life history, they play potentially integral roles in the upland freshwater, nearshore and pelagic marine ecosystems and food webs of Puget Sound. They also provide key trophic links between habitats through their migratory behavior. While there is much variation in the behavior and ecology within and among the different salmonid species in Puget Sound, they typically use freshwater habitats to spawn, after which juveniles emerge and eventually migrate to nearshore estuaries or directly to marine pelagic habitats. The watersheds and nearshore habitats of Puget Sound currently support 8 species of salmon, trout, and charr (NOAA 2007), four of which are listed as Threatened under the Endangered Species Act (ESA). These are Chinook salmon (Oncorhynchus tshawytscha), chum salmon (O. keta), bull trout (Salvelinus confluentus) and steelhead (O. mykiss).

Restoration managers are hopeful that populations of coho, chum and pink salmon will rebound on the Elwha River as the fish take advantage of newly accessible habitat. Part five of our series 'Returning home' examines the importance of genetically distinct salmon runs.

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. 

Migration patterns have apparently reawakened for the Elwha River's wild steelhead. Studies show that the fish may have retained much of their genetic drive despite 100 years of being trapped behind dams. We continue our series 'Returning home: The Elwha's genetic legacy' with part two of seven. 

Our series 'Returning home: The Elwha's genetic legacy' continues with a look at the possible return of spring Chinook to the upper portions of the Elwha River. We bring you part three of seven.

Puget Sound's glaciers are melting rapidly due to climate change. The North Cascades mountains have lost about 56% of their glacial ice while estimates show that glaciers in the Olympics could be gone within the next 50 years. Scientists say salmon and other species could be hard hit as the region loses its “giant storage tank” of ice.
