Status & Trends by Species

Pacific Lamprey


USFWS

Pacific Lamprey is an anadromous fish species, and has been named as a focal species by subbasin planners in 11 subbasins. Status and trends data are available for this species in 4 subbasins. 7 subbasins have no data available. Pacific Lamprey is not a Federally protected species, though it is listed as a "species of concern" in 9 subbasins. No biological objectives have been set for this focal species in the Columbia River Basin.

Lamprey have an elongate, eel-like, flexible cartilaginous body, and skin with no scales. They have no true fins, bones, or jaws. Lamprey enter streams in spring and summer, and spawn the following spring. They spend 4-6 years as larvae in freshwater, before migrating to sea and becoming parasitic adults.

Focal species represent the fish species that the subbasin planners have identified as focal species for the respective subbasin. The biological objectives associated with a focal species were either described in the subbasin plan or were included in state, tribal, or federal recovery/management plans. Biological objectives and current status are linked to their respective reference information; if the reference exists on-line, a link is provided to the original data.

The status and trend information represents the most current data that is available. Data were collected through interviews with biologists and reviews of reports and websites. Each chart is linked to a table of the data, and each datapoint in that table is linked to reference information. The focal species data presented have been reviewed and approved by the respective collectors.
