Pacific Lamprey Research and Restoration : Annual Report 1996.
The once abundant stocks of Pacific lamprey (Lampetra tridentata) above Bonneville Dam are currently depressed (Close et al. 1995). It is likely that many of the same factors that led to the decline of wild stocks of Columbia River Pacific salmon and steelhead have impacted Pacific lamprey populations. The Pacific lamprey is an important part of the food web of North Pacific ecosystems, both as predator and prey. Lamprey (a.k.a. eels) are also a valuable food and culture resource for American Indian Tribes of the Pacific Northwest. Depressed Pacific lamprey runs have impacted treaty secured fishing opportunities by forcing tribal members to gather this traditional food in lower Columbia River locations. The Pacific Lamprey Research and Restoration Project, funded by Bonneville Power Administration, is a cooperative effort between the Confederated Tribes of The Umatilla Indian Reservation, the Columbia River Intertribal Fish Commission, and Oregon State University with the goal to increase Pacific lamprey stocks above Bonneville Dam. The initial objectives of the project are to determine the past and current abundance of Pacific lamprey stocks in major mid Columbia tributaries and at various hydroelectric facilities, and to determine factors limiting Pacific lamprey abundance and distribution. Ultimately, Pacific lamprey restoration plans will be developed and implemented. Part (A)-CTUIR: (1) determine past and present abundance and distribution in NE Oregon and SE Washington tributaries; and (2) determine limiting habitat factors. Part (B)-CRITFC: (1) adult abundance monitoring at Columbia and Snake River dams; (2) juvenile abundance monitoring at Columbia and Snake River dams; and (3) juvenile passage impediments and needed improvements at Columbia and Snake River dams. Part (C)- OSU: (1) adult passage impediments and needed improvements at Columbia and Snake River dams; and (2) juvenile passage impediments and needed improvements at Columbia and Snake River dams.
