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

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
