Snake River fall Chinook Nez Perce Tribal Hatchery Complex
Aaron Penney, NPTHC
Acknowledgments • Funding Sources:
And most important,
Mitigation Goal
• Interim goal of 2,290 hatchery-origin adults above LMO annually from NPTH production
• Long-term goal of 3,750 hatchery-origin adults
above LMO annually from NPTH production • Provide ~1,000 adults annually for broodstock • Develop early returning run to the Selway and S.F.
Clearwater Rivers
Management Objectives • Develop, increase, and reintroduce natural populations
of early-fall, and fall Chinook in the Clearwater River Basin.
• Sustain long-term preservation and genetic integrity of target fish populations.
• Keep the ecological and genetic impacts of non-target fish populations within acceptable limits.
• Provide harvest opportunities for Tribal and non-Tribal anglers.
Juvenile Release Targets
• FCS goal: 1.4M release • 500K sub-yearlings from NPTH into
Clearwater River
• 500K sub-yearlings from North Lapwai Valley AF into Clearwater River
• 200K sub-yearlings from Lukes Gulch AF into S.F. Clearwater River
• 200K sub-yearlings from Cedar Flats AF into Selway River
M & E Objectives • Determine if program targets for contribution rate of
hatchery fish are being achieved and can be improved.
• Estimate ecological and genetic effects to fish
populations. • Determine how harvest opportunities for early-fall,
and fall Chinook salmon can be optimized for tribal and non-tribal anglers within Nez Perce Treaty lands.
• Effectively communicate monitoring and evaluation
program approach and findings to resource managers.
Brief Program History
• Hatchery production began in 2002.
• Broodstock development and collaborative program with Lyons Ferry Hatchery (LSRCP and IPC).
• Working out the kinks with new facility reaching full production.
• Expanding from main NPTH and North Lapwai Valley releases to upstream acclimation releases.

Fish Health Highlights
• Injections of female broodstock with erythromycin three weeks before spawning
• Ovaplant (sGnRHa) pellet injection to accelerate egg maturation in unripe females
• Lower levels of culling for Bacterial Kidney Disease
• Bacterial Gill Disease outbreaks greatly reduced (cooler incubation and rearing temperatures)

Adaptations in response to identified problems
• Ovaplant injections to unripe females. • Cooler incubation and early rearing.
temperatures – No Bacterial Gill Disease. • Changed incubation cleaning protocols. • North Lapwai Valley early releases. • North Lapwai Valley instream water supply
