wfrc.usgs.gov — Since 1994, scientists from the Anadromous Fish Ecology Team have been assisting the U.S. Army Corps of Engineers (USACE) in evaluating the migration behavior and passage of juvenile salmon and steelhead through Lower Granite Reservoir and Dam on the Snake River, WA. The goal of this study is to identify the behavior of individual juvenile salmon More...

wfrc.usgs.gov — The Arctic charr (Salvelinus alpinus) in the northern most latitudes migrate to the ocean in the spring to feed and grow. This results in accumulation of polychlorinated biphenyls (PCB) in their visceral fat. During the winter, the charr reside in freshwater lakes and do not feed. They do mobilize lipids from adipose tissue for energy, which More...

wfrc.usgs.gov — Threatened and endangered salmonids in the Pacific Northwest often use backwaters and wetlands as they migrate toward the ocean, however our understanding of the role of wetlands to juvenile salmonids is limited. The major Objective of this study was to determine whether juvenile steelhead were being tapped on the wetland during spring, and More...

wfrc.usgs.gov — This U.S./Russian collaboration will investigate genetics and life histories of Kamchatka Peninsula rainbow trout and steelhead (O. mykiss), and Dolly Varden, white-spotted, and arctic char (S. malma, S. leucomaensis, and S. alpinus, respectively). Both anadromous and resident forms of these generally occur in Kamchatka rivers that are free from More...

wfrc.usgs.gov — Fall chinook salmon (Oncorhynchus tshawytscha) in the Snake River are currently listed as threatened under the Endangered Species Act (ESA). Because fall chinook salmon migrate seaward during the summer when flows are low and water temperatures are high, their survival rate is lower. The goal of this study is to more clearly identify the More...
