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.
Noted Scientist Emeritus Dr. Wm. Toshio Yasutake Retires - Again!
After a research career lasting more than 60 years and spanning two centuries, WFRC Senior Scientist Emeritus Dr. Tosh Yasutake has decided to retire for the second and (perhaps) final time.
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.

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]
from the Past
- John Beeman is a research fishery biologist at the Columbia River Research Laboratory, Cook, WA. John currently oversees research studies of fish migration and survival, usually related to the effects of hydropower on juvenile salmonids. He typically studies fish movements using some form of telemetry and is currently working on a study to evaluate a prototype fish collector at a high-head dam in Oregon. <MORE>
- Allocation of water among agriculture, fisheries, and municipalities in Oregon's Klamath River Basin, especially in dry years, has long been important to federal and state natural resource planners. But in 1988, when the Lost River sucker and the shortnose sucker were officially listed as endangered species, the lack of unbiased technical information on water quality, quantity, and availability (influenced both by human use and climate) quickly became a critical factor limiting the ability of the USFWS, BOR and other agencies to carry out their legislated responsibilities to manage the Basins scarce water resources. <MORE>
