Columbia River Research Laboratory (CRRL)

Home

The Columbia River Research Laboratory (CRRL) was established in 1978, tracing its roots to the previous Reservoir Program of the Fish and Wildlife Service, in the Columbia River Gorge east of Portland. The CRRL, the Center’s largest field station, carries out research throughout the American West, including Puget Sound, the Columbia River Basin, the Klamath River Basin, and the Sacramento Bay Delta.

Evaluation of factors affecting migration success of adult sockeye salmon (Oncorhynchus nerka) in the Yakima River, Washington, 2020

A study was conducted during June–October 2020 to evaluate factors affecting the migration success of adult sockeye salmon (Oncorhynchus nerka) in the Yakima River, Washington. A total of 144 adult sockeye salmon were tagged and released during the study. Most fish (112 fish) were collected, tagged with passive integrated transponder (PIT), and...

As the prey thickens: Rainbow trout select prey based upon width not length

Drift-feeding fish are typically considered size-selective predators. Yet, few studies have explicitly tested which aspect of prey “size” best explains size selection by drift-foraging fish. Here, we develop a Bayesian discrete choice model to evaluate how attributes of both prey and predator simultaneously influence size-selective foraging. We...
