Pacific Lamprey Research and Restoration: Annual Report 1997
Abstract
The once abundant stocks of Pacific Lamprey (Lampetra tridentata) above Bonneville Dam are currently depressed. 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 as well. The Pacific Lamprey is an important part of the food web of North Pacific ecosystems, both as predator and prey. Lamprey are a valuable subsistence food and cultural resource for Native 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.
