Monitoring & Evaluation Program Status• 1988 - Baseline fall chinook salmon spawning data• 1991 - Baseline spring chinook salmon juvenile and adult data• 1993 - Baseline natural fall chinook juvenile life history data• 2000 - Nez Perce Tribal Hatchery construction begins • 2002 - First spring chinook egg incubation test group and fall chinook egg
incubation• 2003 - First fall chinook juvenile production releases, adult trapping and spawning • 2004 - First spring chinook juvenile production releases

Monitoring & Evaluation Goal
Monitor and evaluate results of the Nez Perce Tribal Hatchery so that operations can be adaptively managed to optimize hatchery and natural production, sustain harvest, and minimize ecological impacts.

Objective 1 Hatchery Product Performance
• Production – Annual Operation Plan• Abundance - Marking, Smolt Yield, Adult Returns• Survival - Smolt, Mainstem Passage, SAR• Distribution - Density, Dispersal, Emigration, Spawning• Stocking Rate - Updated Model, Predict• Fitness Traits - Spawn Timing, Aggressive Behavior,
Habitat Use, Passage Timing, Age-at-Maturity
Determine If Program Targets for Contribution Rate of Hatchery Fish Are Being Achieved and Can Be Improved.
![Page 7: Principal Investigators: Sherman Sprague-Spring Chinook Billy Arnsberg-Fall Chinook Nez Perce Tribal Hatchery Monitoring & Evaluation BPA Project # 1983-350-03.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514ea6255034693478b5be4/html5/thumbnails/7.jpg)
Objective 2 Natural Production Response
• Abundance - Juvenile Abundance/Distribution, Adult Abundance/Distribution
• Habitat - Juvenile, Adult• Life History - Juvenile, Adult, Survival• Environmental Variation - Monitor, Correlation• Density Response - Variable Stocking, Dispersal• Carrying Capacity - Predictive & Available Habitat, Growth, Recruitment,
Limiting Factor
Determine the Increases in Natural Production That Results from Supplementation of Chinook Salmon in the Clearwater River Subbasin, and Relate Them to Limiting Factors.

Objective 3 Interactions
• Genetic - Straying, Variation, Fitness Traits• Competition - Relative Abundance, Predation• Disease - Presence/Absence, Event Triggered
Sampling, Special Concerns

• Baseline data for spring and fall chinook have been collected
• Fall chinook juvenile survivals to Lower Granite Dam have ranged from 14-38% for natural and 42-92% for hatchery fish
• Fall chinook redd counts have increased from a low of 4 redds in the early 1990’s to a high of 573 redds in 2003
• Spring chinook production estimates ranged from 2,308 to 78,096 and survivals to Lower Granite Dam have ranged from 32-88% for natural and 36-89% for hatchery fish
• Spring chinook escapement estimates have ranged from 0-2,636 adults from 1999 to 2003 with a fish/redd estimate of 2.9-14.0
• First NPTH fall chinook releases began in 2003 and 2004 for spring chinook
• First fall chinook adult returns expected in 2005 and spring chinook in 2007
