What has happened to Columbia Basin habitat? Over 1,000 dams have been constructed since the late 1800s. Over 1,000 dams have been constructed since the late 1800s. There are 13 mainstem Columbia and Snake River dams. There are 13 mainstem Columbia and Snake River dams. Only 55% of once-available habitat is still accessible today. Only 55% of once-available habitat is still accessible today. About 65% of remaining accessible mainstem Columbia and Snake River habitat has been transformed to reservoirs/pools About 65% of remaining accessible mainstem Columbia and Snake River habitat has been transformed to reservoirs/pools Common tributary limiting factors due to floodplain development are poor water quantity/quality and lack of stream channel complexity.

Using Traditional, Ecological, Cultural & Science Values Tribes utilize all these to develop and implement programs addressing holistic needs: Goals focused on First Food abundance for traditional/cultural/religious use Goals focused on First Food abundance for traditional/cultural/religious use Target maintenance of harvest opportunities as per treaty right Target maintenance of harvest opportunities as per treaty right Target higher escapement/habitat utilization for full ecological function Target higher escapement/habitat utilization for full ecological function Implement comprehensive fish restoration strategies - all H/gravel-to-gravel Implement comprehensive fish restoration strategies - all H/gravel-to-gravel Emphasis on habitat improvements along with hatchery supplementation where necessary to support rebuilding Emphasis on habitat improvements along with hatchery supplementation where necessary to support rebuilding Seek benefits of using hatchery tool while minimizing risks to wild fish Seek benefits of using hatchery tool while minimizing risks to wild fish

CTUIR DNR/Fisheries Missions & River Vision DNR: To protect, restore, and enhance the First Foods water, salmon, deer, cous, and huckleberry - for the perpetual cultural, economic, and sovereign benefit of the CTUIR. We will accomplish this utilizing traditional ecological and cultural knowledge and science to inform: 1) population and habitat management goals and actions; and 2) natural resource policies and regulatory mechanisms. Fisheries: To provide sustainable harvest opportunities for aquatic species of the first food order by protecting, conserving, and restoring native aquatic populations and their habitats. Umatilla River Vision: The Umatilla basin includes a healthy river capable of providing First Foods that sustain the continuity of the Tribes culture. This vision requires a river that is dynamic, and shaped not only by physical and biological processes, but the interactions and interconnections between those processes.

Purpose of Hatcheries To compensate for impacts of reduced or lost fish production and productivity due to human actions (dam construction, habitat degradation, etc.) Recovery tool to help rebuild natural production (wild fish nurseries) Recovery tool to help rebuild natural production (wild fish nurseries) Mitigation tool to help achieve harvestable populations Mitigation tool to help achieve harvestable populations Hatcheries dont fix factors that reduced productivity Hatcheries dont fix factors that reduced productivity We dont have low fish productivity because of hatcheries, we have hatcheries because of low productivity We dont have low fish productivity because of hatcheries, we have hatcheries because of low productivity

Hatchery Program Types 1.Harvest Augmentation Programs Fish on the table - production for harvest to replace lost natural production Fish on the table - production for harvest to replace lost natural production 2. Reintroduction Programs Fish in habitat and fish on the table - production for harvest and natural spawning in areas that had experienced extirpation Fish in habitat and fish on the table - production for harvest and natural spawning in areas that had experienced extirpation 3. Supplementation Programs Rebuild natural production and fish on the table - production to increase natural production and harvest for depressed populations Rebuild natural production and fish on the table - production to increase natural production and harvest for depressed populations

What Have We Learned? Wrong & Right Hatchery Practices Past hatchery management mistakes: Wrong purpose for hatchery type (try to supplement natural production with a harvest program) Wrong purpose for hatchery type (try to supplement natural production with a harvest program) - broodstock maladapted for target location - select for specific size or run timing - inappropriate juvenile release location - hatchery tool still tainted due to past mistakes

What Have We Learned? Wrong & Right Hatchery Practices Sound hatchery management practices: Select suitable source stock Select suitable source stock For supplementation programs, integrate H & N components For supplementation programs, integrate H & N components - select broodstock from cross section of run - integrate natural & hatchery origin returns into both broodstock and natural spawning population broodstock and natural spawning population - acclimate juveniles to natural production areas - monitor program to inform adaptive management

Defining Hatchery Program Success For Tribes, putting fish on the table or maintaining or increasing harvest opportunities in all usual and accustomed treaty fishing areas is an important success principle for all 3 types of hatchery programs. For Tribes, putting fish on the table or maintaining or increasing harvest opportunities in all usual and accustomed treaty fishing areas is an important success principle for all 3 types of hatchery programs. Increasing spawners and rebuilding natural production to counter the effects of habitat impacts is another success principle. Increasing spawners and rebuilding natural production to counter the effects of habitat impacts is another success principle. Accomplish above using best hatchery management practices to minimize genetic impacts (accept some risk). Accomplish above using best hatchery management practices to minimize genetic impacts (accept some risk). Lack of success = continued population declines, inability to delist or more extinctions. Lack of success = continued population declines, inability to delist or more extinctions.

Tribal Restoration Plan life history survival analysis Most impacted life history stages (~80% reduction) are: Most impacted life history stages (~80% reduction) are: - egg to smolt survival (in tributaries) - juvenile passage (downstream survival in mainstem) Overall adult to adult returns have changed from: Overall adult to adult returns have changed from: fold return pre-development era to - Near 1:1 spawner-to-spawner replacement level When populations are near replacement environmental circumstances become paramount When populations are near replacement environmental circumstances become paramount

Survival Benefits of Hatchery Supplementation The highest rate of natural mortality in the salmon lifecycle occurs in the egg-to-smolt stage (up to 90%) The highest rate of natural mortality in the salmon lifecycle occurs in the egg-to-smolt stage (up to 90%) Artificial propagation can reduce egg-to-smolt loss to ~10% Artificial propagation can reduce egg-to-smolt loss to ~10% Although naturally spawning hatchery fish often produce fewer smolts/redd than wild spawners, the overall adult return from the supplementation program is higher. Although naturally spawning hatchery fish often produce fewer smolts/redd than wild spawners, the overall adult return from the supplementation program is higher. Therefore, a reduced relative reproductive success (RRS) or recruits per spawner (R:S) may not be evidence thatsupplementation treatment is not working (or is working to the detriment of the natural population). Therefore, a reduced relative reproductive success (RRS) or recruits per spawner (R:S) may not be evidence thatsupplementation treatment is not working (or is working to the detriment of the natural population).

Hatchery Benefit vs. Risk (recovery tool or impact?) Benefits: Demographic boost to natural spawning population Avoid extinction, ESA listing or possibly delist Reestablish fisheries in traditional locations Risk of not using tool: Continue deficit returns Continue low natural production Continue low/no harvest Risk of using tool: Reduced genetic diversity Reduced productivity (RRS & RS) Tribal Approach: Seek benefits of using hatchery tool while minimizing risks to wild fish
