Summer research aims to increase salmon, trout, lamprey

MOSCOW - In an effort to boost stocks of steelhead trout, chinook salmon and Pacific lamprey, a team of University of Idaho researchers will begin a three-faceted study in the coming months.

A $2.7 million grant from the U.S. Army Corps of Engineers is supporting the work.

Co-investigator Christopher Caudill is an assistant professor in the Department of Fish and Wildlife Sciences in Moscow. He said three related studies will be conducted on the Federal Columbia River Power System, the Snake River and on the Willamette River, all of which are affected by dams.

The projects, which fall under a federal program launched in 1997, will include a blend of engineering ingenuity, fish telemetry and underwater acoustic camera monitors. Fieldwork will be conducted this summer with analyses and preliminary findings to be published in 2014.

Researchers will:

"We'll be looking at the effectiveness of the lamprey passage system, which begins with an entrance for migratory lamprey and salmon below Bonneville Dam," Caudill said.

If successful, dams along the Columbia and Snake rivers may install fish ladders in the new design, which may significantly increase populations of native fish populations that are so important to the heritage and culture of Americans, beginning with the region's indigenous Indian tribes. Similarly, the salmon studies will contribute to regional salmon recovery efforts currently under way by regional, federal, state and tribal agencies.

Additional participants include: the UI Echohydraulics Research Laboratory in Boise, the National Marine Fisheries Service, the U.S. Forest Service Rocky Mountain Research Station, the Oregon Department of Fish and Wildlife and Oregon State University's Cooperative Fish and Wildlife Research Unit.
