1 Determining lamprey species composition, larval distribution and adult abundance in the Deschutes River sub-basin Jennifer Graham & Chris Brun Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

2 Confederated Tribes of Warm
Project Area Confederated Tribes of Warm Springs Reservation Oregon Oregon

3 Objectives Objective 1: Determine larval distribution and associated habitat Objective 2: Determining species composition of Lampetra Objective 3: Estimate the number of lamprey outmigrants by developmental stage Objective 4: Estimate the escapement of adult lamprey, determine harvest and harvest rates at Sherar’s Falls. Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

4 Larval Distribution and Associated Habitat

5 Methods Randomly selected 1 sample site per 10 Rkm May - August
Three-tiered sampling methodology Objective 1 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

6 Methods – Habitat & Water Quality
Tier 2 – Transect Wetted Channel Width Bankfull Channel Width Canopy Density Tier 3 – Sub-sample Mean Water Depth Water Velocity Substrate Composition Habitat Type 1m x 1m Tier 1 – Reach Conductivity Dissolved Oxygen Water Temperature Channel Slope 60-m Objective 1 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

7 Methods – Lamprey sampling
Tier 3 – Sub-sample Backpack electrofisher (AbP-2) 2, 90-s samples Lamprey Anesthetized, identified, weighed and measured Returned to collection area Using a specialized larval lamprey backpack electrofisher, 2, 90-s backpack electrofishing passes were conducted. Collected lamprey were anesthetized, identified, weighed, measured. Lamprey were released back to the collection area after recovering from the anesthesia. Objective 1 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

8 Results - Streams 4 of 13 streams sampled contained ammocoetes
132 sub-sampled 29.5% contained ammocoetes Sampled 13 streams in 2003, ammocoetes were present in 4 Within those 13 streams, 132 sub-samples were completed and ammocoetes were present in 39 (29.5%) Present in low gradient areas in the lower reaches of the four streams they were present Present in lowest reaches

9 Total length range: 25 mm – 145 mm
Results – Lamprey 131 ammocoetes collected Total length range: 25 mm – 145 mm Mean total Length: 77 mm A total 131 ammocoetes were collected. Lengths ranged from mm with a mean length of 77 mm. The number of ammocoetes collected at each site was highly variable. Objective 1 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

10 However, sample sizes were small!!
Regression P-Value Lamprey presence vs. Woody debris Lamprey presence vs. Depositional Area However, sample sizes were small!!

11 2004 Summary Conducted sampling in three tributaries
Determined distribution Continue larval distribution and habitat data collection Remainder of perennial streams in the lower Deschutes Mainstem Deschutes

12 Species Composition

13 Methods & Results Field identification problematic
Collect samples for permanent collection Electrofishing Rotary screw trap Collect specimen in three different phases of development Only observed species in two phases Objective 2 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

14 2004 Summary Continue collecting samples
Send problematic samples to USGS Objective 2 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

15 Estimate outmigrants and
outmigration timing

16 Methods Fished 2 screw traps 5 days/wk; 24 hrs/day Collected lamprey
Anesthetized Identified to species Developmental stage Length Objective 3 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

17 2002-2003 Screw Trap Summary Warm Springs Shitike River Creek
Days Operated Days with lampreys present Ammocoetes Collected Ammocoete Length Range (mm) Ammocoetes Mean Length (mm) Macropthalmia Collected Macrophtalmia Length Range (mm) Macropthalmia Mean Length (mm) Objective 3 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

18 Results – Warm Springs Timing

20 Results – Shitike Creek Timing
Objective 3 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

21 Trap efficiencies Ammocoetes captured through electrofishing
Marked with elastomer Placed in holding box Checked after 24 hours Multiple trap holding efficiencies 0% holding efficiency No out-migrant estimates completed Objective 3 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

22 2004 Summary Continue collecting timing data Modify existing traps
Conduct trap efficiencies Mark-recapture to estimate out-migrant numbers

23 Escapement Estimate and Tribal Harvest

24 Sherar’s Falls

25 Methods – Escapement “Lamprey pots” (USFWS) Late-June – early-July
Multiple modifications Fished various locations in fish ladder Long-handled dip net Late-June – August Fished each pool 1 time/hr Same location each time Objective 4 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

26 Results - Tagging Floy Tag Fin Clip 199 Lamprey Tagged

27 Results – Recapture 35 Recaptures (17.6% recapture rate)
11 Netting; 22 Creel; 2 Tribal member returns Primary Tag Retention 77% Objective 4 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

28 Methods – Tribal Harvest
Access site creel survey Mid-June - August 4 weekdays; 1 weekend day 1 hr. after sunset – 3 am Creeled lamprey Examined for fin clip and floy tag Total length measured Creel data expanded to estimate total tribal harvest Objective 4 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

29 Results – Tribal Harvest
Roger Jim, Sr. Celilo Falls 21 interviews conducted 585 lamprey collected 960 estimated harvest 9.25 lamprey/hr Mean length: 62 cm Range: cm

30 2004 Summary Mark-Recapture Study Estimate escapement Tag retention
Average movement rate Tribal Harvest Creel surveys

31 Larval lamprey & Habitat
Conclusions Objective 1 Larval lamprey & Habitat Lamprey were present in 4 of the 13 streams sampled Complex habitat needs including depositional areas and woody debris Small sample sizes made it difficult to find relationships with lamprey presence Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

32 Species Identification
Conclusions Objective 2 Species Identification Permanent collection Collected through electrofishing and rotary screw trap operations Only observed/collected 2 or the 3 developmental stages Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

33 Conclusions Objective 3 Timing Shitike Peak movement: 2002 – March
2003 – December WSR Ammocoetes Macropthalmia Peak movement: March March May December Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

34 Tribal Harvest & Upstream migration
Conclusions Objective 4 Tribal Harvest & Upstream migration Adult Escapement Estimate Marked 199 adult lamprey Recaptured 35 Tag retention 77% Tribal Harvest 21 creel interview conducted – 585 lamprey Estimated harvest 960 Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

35 Conclusions 2004 Summary Objective 1: Larval lamprey collection
Habitat Objective 2: Species identification Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources

36 Conclusions 2004 Summary Objective 3: Collect timing data
Conduct trap efficiencies Objective 4: Estimate escapement Monitor tribal Harvest Confederated Tribes of Warm Springs Reservation, Oregon Department of Natural Resources
