IDFG Management Objectives for the Salmon River
–Restore and maintain natural populations in the Salmon River–Restore and maintain recreational and
tribal fisheries–Achieve LSRCP adult mitigation goals–Minimize impact of hatchery program on
natural populations
![Page 5: LSRCP Hatchery Steelhead Salmon River Brian Leth and Carl Stiefel LSRCP Steelhead Program Review July 20-21, 2012 Clarkston,WA](https://reader035.vdocuments.us/reader035/viewer/2022062906/5a4d1b247f8b9ab059996557/html5/thumbnails/5.jpg)
• Salmon River Major Population Group (MPG)- – None of the twelve
populations meet viability criteria
– All populations classified at moderate-high risk for A/P and low-moderate for SS/D
– Lack of population specific A/P estimates
• Campbell and Vogel presentation to discuss recent work at Lower Granite Dam

Implementation of the Mitigation Program
Primary focus for hatchery program is to provide harvest mitigation benefits– Two general life history types in the Salmon River
• A-Run (Predominately 1-ocean returns)• B-Run (Predominately 2-ocean returns)
– Maintain four hatchery stocks to achieve mitigation objectives
– Utilize LSRCP, IPC, and COE facilities
– One hatchery component focused on supplementation strategy
![Page 12: LSRCP Hatchery Steelhead Salmon River Brian Leth and Carl Stiefel LSRCP Steelhead Program Review July 20-21, 2012 Clarkston,WA](https://reader035.vdocuments.us/reader035/viewer/2022062906/5a4d1b247f8b9ab059996557/html5/thumbnails/12.jpg)
Salmon River Hatchery Broodstock History
• Snake River steelhead (Hells Canyon Dam) were transferred to Salmon River in 1966 at Pahsimeroi Fish Hatchery (PFH)- the PahA stock
• The locally adapted stock at PFH was extended to Sawtooth Fish Hatchery in 1984- the SawA stock
• B-run steelhead brought into the upper Salmon River (at PFH) from Dworshak Fish Hatchery in 1973- the DworB stock. – Transitioning to locally adapted B-run stock- the USRB stock
• East Fork Salmon River (EFSR)- the East Fork integrated stock. A history of both DworB and PahA hatchery releases in the EFSR

• Managed to provide in-kind harvest mitigation for larger 2-Ocean steelhead in the Salmon River
• Dworshak Fish Hatchery (Clearwater River) smolts released in the Salmon R. since 1973
• Goal to replace all DNFH stock in the Salmon and Little Salmon rivers with a locally adapted stock

Description of Salmon River ProgramUpper Salmon B-Run
– Ineffective broodstock collection has limited program
– Since 2001, smolt releases from local returns have been 60-120k.• Goal is ~900,000 smolts
– In 2009 moved broodstock collection to Pahsimeroi Fish Hatchery (PFH)
– Returns in 2013 from first smolt release at PFH
• expected to meet majority of the upper Salmon River egg needs
– PFH only intended to serve as a temporary location

Description of Salmon River ProgramUpper Salmon B-Run
• Moving forward to shift program to Yankee Fork– concurrently with SBT effort to develop

• Expectations for increased adult returns as DworB releases are phased out
• This brood will also be used to replace DworB releases in the Little Salmon R.

• Integrated broodstock
• 170,000 smolt release
• Spawning and rearing habitat in EF downstream of the EF weir.
• Currently limited to monitoring adult escapement at EF weir.
• Identified need to develop trapping site lower in the system (FCRPS Biop RPA 42; HSRG, HRT, and HGMP)

Description of Salmon River ProgramsEast Fork Salmon River
Program Limitations and Future Direction- Inability to assess or control escapement in the EFSR- Absolute need
- Develop effective trapping facility in lower EFSR
- Reducing the size of the hatchery program (40-60k) - More influence from natural population- Target 100% natural broodstock- No restriction on hatchery returns released to spawn
naturally

Fish Health/Disease
• Overall, disease has not limited the ability to meet smolt production targets
• Hagerman National Fish Hatchery– In Recent Years: Furunculosis, Sore back, Coldwater
Disease– In Past years: IHN, and Bacterial gill disease– DworB stock was problematic
• Magic Valley Fish Hatchery– Coldwater Disease and IHN

Summary of Salmon River Program
Hatchery productionNo significant limitations with fish culture
Post release survivalJuvenile survival consistently >70%
Exceeded project area escapement goals in all of last 10 years
Have achieved total mitigation goals in only two years
![Page 42: LSRCP Hatchery Steelhead Salmon River Brian Leth and Carl Stiefel LSRCP Steelhead Program Review July 20-21, 2012 Clarkston,WA](https://reader035.vdocuments.us/reader035/viewer/2022062906/5a4d1b247f8b9ab059996557/html5/thumbnails/42.jpg)
Summary of Salmon River Program
Harvest Benefits– Contribution below project area less than originally
anticipated
– Appears that we are underestimating harvest below project area
– Consistently provides robust fisheries and harvest opportunity above project area• Average number harvested 16,700 (range: 3,000-47,000)• Angler Effort 219,00 angler days (range: 136,000-382,000)• Project Harvest Rates- 60-80%
– Economic benefits to many rural communities
![Page 43: LSRCP Hatchery Steelhead Salmon River Brian Leth and Carl Stiefel LSRCP Steelhead Program Review July 20-21, 2012 Clarkston,WA](https://reader035.vdocuments.us/reader035/viewer/2022062906/5a4d1b247f8b9ab059996557/html5/thumbnails/43.jpg)
Monitoring and Evaluation
Continued monitoring of hatchery production and productivity– PIT Tagging
• Estimating adult survival• Migration timing and inter-dam conversion• Strays
– Parental Based Tagging (PBT)• Adult survival• Catch contribution• Stock Identification• Strays
– Run Reconstruction at LGD
![Page 44: LSRCP Hatchery Steelhead Salmon River Brian Leth and Carl Stiefel LSRCP Steelhead Program Review July 20-21, 2012 Clarkston,WA](https://reader035.vdocuments.us/reader035/viewer/2022062906/5a4d1b247f8b9ab059996557/html5/thumbnails/44.jpg)
Moving Forward• Continue to focus hatchery effort to provide harvest mitigation
benefits
• Continue to maintain conservation management areas for wild populations
• Continue to evaluate effectiveness of hatchery tool to provide conservation benefits
• Maintain flexible adaptive management approach. Include new science and information to help guide best management practices
• Continue collaborative apporach with federal, state and tribal partners in managing the hatchery program
• Increase information base on abundance and productivity of natural populations
