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).

Seals and sea lions may be slowing salmon recovery, hurting orcas

Increased consumption of Chinook salmon by seals and sea lions in the Salish Sea “could be masking the success of coastwide salmon recovery efforts,” according to a new study published in the journal Scientific Reports. Endangered resident orcas are said to be declining in part due to a lack of available Chinook, the orcas' preferred prey.

Are we making progress on salmon recovery?

In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. In this article, we look at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask.
