Monitoring & Evaluation Plan for the Nez Perce Tribal Hatchery
Steward,1996 Hesse & Cramer, 2000
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.
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
Estimate Ecological and Genetic Impacts to Fish Populations.
Objective 4 Harvest Management
• Abundance – Ocean and Columbia, Clearwater• Distribution – Ocean, Freshwater• Run Prediction – Run Predictor, Optimal
Escapement, Fishing Method, Catch & Release
Determine How Harvest Opportunities on Spring, Early-fall, and Fall Chinook Salmon Can Be Optimized for Tribal and Non‑tribal Anglers Within Nez Perce Treaty Lands.
Objective 5 Applied Adaptive Management
• Data Management - StreamNet, PTAGIS, RMIS• Results - SOW, Qtr. Reports, Summary Reports,
ESA Reports, Annual Reports, Five-year Reports, Journal Publications, Conferences and Workshops
• Coordination - AOP, Coordination Meetings, RME Working Group
• NPTH Operations - NATURES Design Team, Five-year Symposium
Effectively Communicate Monitoring And Evaluation Program Approach And Findings to Resource Managers.
