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).

Many of Puget Sound's Chinook salmon spend their entire lives in local waters and don't migrate to the open ocean. These fish tend to collect more contaminants in their bodies because of the sound's relatively high levels of pollution.

Food webs are natural interconnections of food chains and depict what-eats-what in an ecological community. While Puget Sound represents a specific food web, the organisms that reside within that web often travel outside the region. In this way, one community's food web can be drastically affected by a change in a neighboring ecosystem.
