ENDEMIC BROODSTOCK DEVELOPMENT TUCANNON AND TOUCHET RIVERS
PROGRAM REVIEW
Joe BumgarnerWashington Department of Fish and Wildlife
Background ESA listings of steelhead (Snake, Mid-Columbia)
Bi-Op concluded that LFH stock steelhead constituted “jeopardy” to wild populations
Bi-Op recommended new broodstock(s) be developed
Tucannon and Touchet - Target Populations Local, easy access, existing facilities
5-Year feasibility (12th year)
WDFW Management Intent
Concept: Replacement of LFH stock in each river IF programs were successful
Tucannon (depressed, declining)
#1 : Conservation #2 : Harvest Mitigation
Touchet (depressed, stable)
#1 : Harvest Mitigation
“Test Phase”Production Goals
LocationNumber of
SmoltsSAR
Survival
Tucannon 50,000 0.5%Touchet 50,000 0.5%
+ LFH Stock Production
**Fish were not Externally Marked = Conservation
Management Objectives(Short Term)
Establish endemic broodstocks
Return adults and achieve SAR’s (= to LSRCP goals)
Remove the potentially depressing effect of a long-term out-of-basin hatchery stock on ESA listed populations
Program is compliant with ESA and WDFW Policies to protect and recover wild stocks
Evaluation Focus
Performance in Hatchery
Adult Returns to Each River Increase our understanding of the status and trends of
natural origin steelhead in each river
Smolt-to-Adult Survivals

Previous Hatchery Influence?
LFH Stock steelhead released in both Tucannon and Touchet Basins for 20 years
Spatial and Temporal overlap in spawning
Possible Genetic Introgression
Is This Worth the Effort??

Genetic Data(Chord-distance tree)
5-Year Assessment Fish Were Available for Broodstock
Distinct Stocks (similar)
Adult Traps Inadequate for Evaluations Transition to PIT Tags for Adult Return Evaluation
Issues at Hatchery (Spawning and Rearing) Unripe/not enough Males, Multiple Eggtakes Poor Feeding, Size Goals not achieved, High CV’s, etc….
12 Years Later Where Are We Today?
Tucannon: Implemented (2010)Interim Goal: 75K – 100% conservation
Long Term Goal: 150K 50K - conservation100K - harvest mitigation
Touchet: No Decision

Tucannon River Summary
Implemented Tucannon Program in 2010 (Bi-Op RPA) Elimination of LFH stock
Smolt Production ↑ to 75,000 150,000 Goal (50K – Conservation, 100K – Harvest Mitigation) Additional Facilities at LFH Required
BPA Funding for ↑ monitoring (Bi-Op RPA) ↑ PIT’s and PIT Arrays to better estimate adult returns and
distribution for natural and endemic stock in Tucannon River
Tucannon River Summary (cont)
SAR’s and Adult Returns to LSRCP project area are meeting goals, but not to Tucannon River
Straying (“OUT” and “IN”) Hydro-system/natural behavior/environmental?
Population Definition and Abundance? Future Fishery Plans within Tucannon River at Risk?
Touchet River Summary Program has remained Status Quo
Poor SAR’s and Adult Returns 2-year smolt program Acclimation?
Based on performance to date – LFH stock replacement is not an option (WDFW)
Conservation Program?? Identified in Bi-Op
