1 Principal Investigators: Sherman Sprague-Spring Chinook Billy Arnsberg-Fall Chinook Nez Perce Tribal Hatchery Monitoring & Evaluation BPA Project # Nez Perce Tribe Department of Fisheries Resources Management

2 Monitoring & Evaluation Plan for the Nez Perce Tribal Hatchery Steward,1996 Hesse & Cramer, 2000

3 Monitoring & Evaluation Program Status Baseline fall chinook salmon spawning data Baseline spring chinook salmon juvenile and adult data Baseline natural fall chinook juvenile life history data Nez Perce Tribal Hatchery construction begins First spring chinook egg incubation test group and fall chinook egg incubation First fall chinook juvenile production releases, adult trapping and spawning First spring chinook juvenile production releases

4 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.

5 Yoosa/Camp Creek Meadow Creek Allotment 1705 (NPTH) Newsome Creek Lukes Gulch Cedar Flats Sweetwater Springs North Lapwai Valley Hatchery Facility Satellite Facility Crooked River Red River Spring Chinook Areas Fall Chinook Areas

6 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.

7 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.

8 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.

9 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.

10 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.

31 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 1990s 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 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 Summary
