Pacific Lamprey Monitoring
and Data Management
Yakama Nation FRMP
Pacific Lamprey
Recovery Project

2. Project Goals
The goal of the Yakama Nation is to restore natural
production of Pacific lamprey to a level that will
provide robust species abundance, significant
ecological contributions and meaningful harvest
throughout the Yakama Nations Ceded Lands and in
the Usual and Accustomed areas.

3. Pacific Lamprey Adult Counts

4. Premises
• Yakima population is functionally
extirpated
• Our goal is to have hundreds and
thousands of juveniles
 Supplementation a much needed tool
• Genetics (risk management approach)

5. Monitoring Projects
• Adult passage (radio telemetry)
• Juvenile passage (Prosser Dam) -> index?
• Juvenile present/absence (including canals)
• Juvenile index sites (“relative abundance”)
• Water quality impacts on lamprey (adult/juv.)
• Artificial propagation and rearing (methods, feed)
• Supplementation effectiveness (survival and
growth)

6. Juvenile Surveys
• Exploratory Survey (Min. Data)
 Presence / Absence
 Quick survey
• Index Survey (Core Data)
 Relative abundance
 Annual variation
• Extensive Surveys (Optional Data)
 Release from art. prop.
 Seasonal variation
 Growth, distribution, habitat use

7. Focus
• Need a method to measure
“relative abundance” of larvae
 Time & Space
 Consistent
& Coordinated
 Precision not important
 Density can be misleading

12. Use Existing Data
• Flow
• >14 cfs
ODFW Steelhead Survey
• Gradient
• <2%
• Valley Width
• > 100 ft

13. Benefits of IP Model
for Pacific Lamprey
• Higher efficiency in predicting
lower and upper distribution
• Make comparison
of density and
relative abundance
more meaningful

14. Spatial Scales
• 3 spatial scales
• 10 M: density, habitat
features
• 100 M: relative
abundance, status and trend
• 1000 M: abundance
estimates, status and
trend, limiting factors

16. Index Sites
density measurements in representative
habitat types -> “relative abundance”
• ~100 meters Area
• 3-5 plots, fixed and mapped Supplemented
• Each Plot = X amount of area surveyed over
Y amount of time (~10 m)
• Long-term
Extensive Sites
growth, survival and habitat preference
of released propagated larvae.
• ~100 metes
• Extensive area surveyed
• Location may vary over time

17. How to Calculate
Abundance?? = 250 m2
• Estimate area for Type 1 & 2
Habitat (using habitat surveys)
• Not always available
(Larger streams/rivers)

18. Core Data
Reach Scale (~1000 m)
• Watershed (HUC 5 or 6)
• Stream Name
• GPS
• (River Mile -> identifier)
• (Elevation)
• (Gradient)
• (Sinuosity)

19. Core Data
Habitat Scale (~10 m)
• Channel type (riffle, glide, pool)
• Habitat Type (% Type 1 & 2)
• Plot size
• Method (E-fishing, hand net, etc)
• Survey time (cpue)
• Time of day
• Visibility (high, medium, low)
• (Conductivity)
• (Temperature/DO/pH)
• (Riparian / % cover)

20. Biological Core Data
• Species (at least %)
• Life stage
• Counts
• (Length)
• (Weight)
