Research at the Western Fisheries Research Center focuses on the environmental factors responsible for the creation, maintenance, and regulation of fish populations including their interactions in aquatic communities and ecosystems. Within these pages you will find research information on Pacific salmon; western trout, charr, and resident riverine fishes; desert and inland fishes; aquatic ecosystems and their resources, and many other topics.

Where the Stream Meets the Road: Prioritizing Culvert Replacement for Fish Passage
In a project supported by the North Pacific Landscape Conservation Cooperative, USGS researchers developed and implemented an approach for prioritizing culvert replacements that included considerations of fish access, culvert replacement costs, and potential climate change impacts on the risk of culvert failure.[Read more]
Steelhead Life History Study in White Creek on the Yakama Nation Reservation
White Creek is a tributary of the Klickitat River that is entirely within the Yakama Nation Indian Reservation. Fishery biologists from the U.S. Geological Survey have teamed with fishery biologists from the Yakama Nation to conduct a life history study of the juvenile steelhead using small electronic tags.

Puget Sound Fall Chinook Estuarine Utilization
The widespread loss of estuarine and nearshore habitats throughout Puget Sound comes at a price. Puget Sound Chinook salmon are just one of many species whose populations have declined to precariously low levels (ESA threatened status) due to a variety of perturbations, including estuarine and coastal development. [Read more]
Spawning Lost River suckers
Lost River suckers are long-lived catostomids endemic to the Upper Klamath River Basin in Oregon and California. They were listed as endangered under the U.S. endangered Species Act in 1988 because of range contractions, declines in abundance, and a lack of evidence of recent recruitment to adult populations.

Rock Creek Fish Population and Life History Assessment (Washington)
The stock of steelhead (Oncorhynchus mykiss) present in Rock Creek has been listed as "threatened" under the Endangered Species Act. The research conducted by the USGS, in coordination with the Yakama Nation, is designed to determine stream habitat conditions, fish abundance, and fish life history characteristics such as movement, growth, and distribution.

Zebrafish (Danio rerio)
Zebrafish are a small (3 to 4 cm), tropical, freshwater, cyprinids that are very popular ornamental/aquaria fish species. This fish species has become a powerful model organism for the study of vertebrate biology, developmental and genetic research, and more recently infectious disease studies. [Read more]

  • Dave Hewitt is a research fishery biologist at the Klamath Falls Field Station, Klamath Falls, Oregon. Dave helps guide a research and monitoring program for two endangered catostomids Lost River and shortnose suckers in the Upper Klamath Basin of Oregon and California. Dave and his colleagues are using quantitative tools such as capture-recapture to investigate the ecology of the two sucker species and factors inhibiting their recovery. <MORE>
  • In 2004, WFRC initiated a historic long-term collaborative research project with federal, state, and tribal partners on the ecological effects of removing the Elwha and Glines Canyon dams on the Elwha River, Washington. <MORE>
