Nez Perce Tribal Hatchery Complex Program Overview Nez Perce Tribe Department of Fisheries Resources Management
Teamwork Confederated Tribes of the Umatilla Indian Reservation
NPTH Purpose • Develop, increase, and reintroduce natural populations of spring, 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 nontarget fish populations within acceptable limits. • Provide harvest opportunities for Tribal and non-Tribal anglers.
NPTH Production Goals • FCS goal: 1. 4 M release – 500 K subyearlings from NPTH into Clearwater River – 500 K subyearlings from North Lapwai Valley AF into Clearwater River – 200 K subyearlings from Luke’s Gulch AF into S. F. Clearwater River – 200 K subyearlings from Cedar Flats AF into Selway River • SCS goal: 825 K release – 200 K Yearlings from NPTH into Clearwater River – 150 K Presmolts from Yoosa/Camp AF into Lolo Creek – 75 K Presmolts from Newsome AF into Newsome Creek – 400 K Parr from NPTH into Meadow Creek (no acclimation)
NPTHC Area of Influence
Nez Perce Tribal Hatchery • Constructed in June 2000 through Oct. 2002 • Four ground water wells • Four surface water pumps • Eight Krebs sand filters • Zero Gravity filter System • UV system • Chiller • Automated temperature control • Backup Generator
Sweetwater Springs Early rearing facility • Used by IDF&G until 1978 • Upgraded and used by NPT beginning in 1993 • Officially transferred in 1998 • Further modifications in June – December, 2001
North Lapwai Valley Acclimation 500 K FCS subyearlings • Constructed in Dec. 2000 through Sep. 2001 • Located on Lapwai Creek near Clearwater River • Pumped Lapwai Creek water
Luke’s Gulch Acclimation 200 K FCS subyearlings • Constructed from May through August 2001 • Located on S. F. Clearwater River • Partial setup/takedown • Portable pumps & Generator
Cedar Flat’s Acclimation 200 K FCS subyearlings • Complete setup/takedown by NPTH staff each year • Located on Selway River • Portable pumps & generator
Newsome Creek Acclimation 75 K SCS presmolts • Constructed from Jun. 2000 through Sep. 2001 • Located on Newsome Creek…tributary of S. F. Clearwater River • Gravity fed creek water
Yoosa/Camp Creek Acclimation 150 K SCS presmolts • Constructed from Jun. 2000 through Sep. 2001 • Located at Confluence of Yoosa & Camp Creeks (tributaries of Lolo Creek) • Gravity fed water from both creeks
Meadow Creek (Selway River) 400 K SCS parr • Direct stream release • Helicopter outplanted

“NATURES” Rearing Planned: • Low density index • Mimic stream temperatures • Pathogen & silt free river water • Natural “S” channel rearing • Natural pond substrate • Exercise program • Volitional release Currently Used: • Low density index • Partially treated river water • Natural “S” channel rearing • Natural pond substrate • “S” channel only exercise • Volitional release
Things That Work • • Incubation temperature control Early rearing temperature control Low density rearing Well control – Variable drives – Automated and prioritized • • • Hatchery Automation Round tanks “Low impact” acclimation sites
Things That Didn’t Work • • • Acclimation site adult holding/spawning Hatchery Automation Some natures components – Stream temperature incubation – Exercise program mostly abandoned – No predation control – “S” Channels not culture friendly • Production based on 100% expected water use • Lack of flexibility in engineering
Key Challenges • Well water issues • Acclimation site intakes • Limited river water treatment – Filtration limitations UV limitations – Undersized heat exchanger • SCS adult holding mortality • Missing weirs – Broodstock collection – Program evaluation
So You Want To Build A Hatchery? • • Budget some “extra” production water Design every component for flexibility and adaptability Hire your Manager before you build Assemble a Technical Work Group in advance Label every component in fish culture speak Write your SOP in fish culture speak Demand a water/alarm system map Think long term and outside the box – Energy efficiency – What are the private growers doing? Our neighbors to the north?
Biggest key to success?
