Contract Title:  :  Evaluate Habitat use and population dynamics of lamprey in Cedar Creek
Performance/Budget Period:  1 January 2005 to 31 December 2005

Contract Background Section:

Three lamprey species (Lampetra tridentata, L. ayresi, and L. richardsoni) occur in the Columbia River basin (Kan 1975).  Pacific lampreys (L. tridentata) in the basin have declined to only a remnant of their pre-1940s populations (Close et al. 1995) and the status of the river lamprey (L. ayresi) and the western brook lamprey (L. richardsoni) is unknown.  The ecological, economic, and cultural significance of these species, especially the Pacific lamprey, is grossly underestimated (Kan 1975, Close et al. 1995).  Though biological and ecological information for these species is available (e. g. Pletcher 1963, Beamish 1980, Richards 1980, Beamish and Levings 1991), few studies have been conducted within the Columbia River basin (Kan 1975, Hammond 1979, Close 2001).  Actions are currently being considered for the recovery of Pacific lamprey populations (Close et al. 1995).

Identifying the biological factors that are limiting lamprey success in the Columbia River basin is critical for their recovery. Availability and accessibility of suitable spawning and rearing habitat may affect the amount of recruitment that occurs within a basin (Houde 1987 Potter et al. 1986).  Factors such as food base, disease, competition, and predation also need to be examined.  Moreover, studying lamprey population dynamics is essential for developing and evaluating management plans (Van Den Avyle 1993).  Population assessments allow for the description of fluctuations in abundance and measure responses to environmental disturbances. Such knowledge may eventually allow the use of mathematical models to predict future trends relative to alternative management strategies.

The United States Fish and Wildlife Service, Columbia River Fisheries Program Office (CRFPO), has received funding from Bonneville Power Administration to monitor adult and juvenile lamprey in Cedar Creek since 2000 to describe life-histories and investigate factors affecting lamprey.  Cedar Creek is a third-order tributary to the Lewis River, whose 89.3 km2 drainage includes diverse stream types and habitat conditions.  Fish access to Cedar Creek is uninhibited by dams or the effects of mainstem Columbia River hydropower facilities.  Pacific lamprey, western brook lamprey, and possibly river lamprey are found in Cedar Creek (Dan Rawding, Washington Department of Fish and Wildlife, personal communication).

Activities of the CRFPO in the Cedar Creek project have focused on both juvenile and adult lamprey.  Activities for juvenile lamprey have included monitoring the abundance and timing of movement of individuals by operating a rotary screw trap (Stone et al. 2001, 2002; Pirtle et al. 2003; Lê et al. 2004), investigating the distribution and habitat use of larvae (Stone and Barndt in press), and assessing the susceptibility of larvae to electrofishing.  Activities focused on adults have included describing timing and habitat used by spawning Pacific lamprey, and collecting individuals to describe their biological characteristics and estimate abundance.  In addition to providing essential information describing lamprey inhabiting Cedar Creek, these activities are assisting in the evaluation of methods that may be applicable to studies of lamprey in other areas of the Columbia River basin.

This statement of work represents a continuation of the project with the specific objectives to: 1) Calculate estimates of abundance for adult Pacific lamprey and describe biological and behavioral characteristics; 2) Describe spawning habitat used by Pacific lamprey and assess approaches to monitor spawning activity in select stream reaches; 3) Estimate abundance of larvae and recently metamorphosed lamprey, and describe biological and behavioral characteristics; and 4) Determine susceptibility of larval lamprey to electrofishing, and assess electrofishing as a tool for determining presence and estimating abundance of larval lamprey.

Objective 1:
Calculate estimates of abundance for adult Pacific lamprey in Cedar Creek, and describe biological and behavioral characteristics.

Objective 2:
Describe spawning habitat used by Pacific lamprey and assess approaches to monitor spawning activity in select stream reaches.

Objective 3:
Estimate abundance of larvae (ammocoetes) and recently metamorphosed lamprey (macropthalmia), and describe biological and behavioral characteristics.

Objective 4:
Determine susceptibility of larval lamprey to electrofishing, and assess electrofishing as a tool for determining presence and estimating abundance of larval lamprey.
