  4. 4. Nisqually Hatchery Chinook Release Timeline HSRG Recommendations Kalama Creek Clear Creek Johnny Appleseed Outplants
  5. 5. The Johnny Appleseed Era Salmon Egg <ul><li>From 1942 – 1990 releases of up to 2 million Chinook/year were made at various locations throughout the basin. </li></ul><ul><li>A variety of Chinook stocks were used and included fish from Green River, Deschutes, Hood Canal, Samish, and others. </li></ul>
  6. 6. McAllister Creek Hatchery <ul><ul><li>Operated from 1982 to 2002 </li></ul></ul><ul><ul><li>Release targets = 1 million zero-age Chinook and 300k yearlings </li></ul></ul><ul><ul><li>Poor water quality, high incidence of parasites, poor attraction, and other concerns prompted HSRG to recommend that the Chinook program be discontinued </li></ul></ul>
  7. 7. Nisqually Chinook Hatchery Production Current Conditions <ul><li>Goal: Provide sustainable harvest for tribal commercial and sport fishers. </li></ul>
  8. 8. Kalama Creek Hatchery <ul><ul><li>Located on river mile 9.2 </li></ul></ul><ul><ul><li>Releases began in 1980 and varied in size from .5 – 1.3 million Chinook </li></ul></ul><ul><ul><li>Since early 90’s current releases number approximately 600,000 and broodstock are from Nisqually returns </li></ul></ul>
  9. 9. Clear Creek Hatchery <ul><ul><li>Located on river mile 6.2 </li></ul></ul><ul><ul><li>Releases began in 1991 and average 3.5 million zero-age Chinook </li></ul></ul><ul><ul><li>All broodstock are from Nisqually returns </li></ul></ul>
  10. 10. Clear Creek and Kalama Creek Hatchery Vital Statistics Period Hatchery Program Purpose Program Type Broodstock Management HOR (adults) Program Size (million) Marking Objectives Baseline and Current Kalama Creek Harvest Segregated 420 0.6 65,000k CWT/ad clip; 100% of program ad clip Clear Creek Harvest Segregated 2,321 3.4 200,000 CWT/ad clip; 200,000 CWT no ad clip; 3.0 million ad clip only Notes: HOR: hatchery-originated recruits, CWT=coded wire tag, ad clip= adipose fin clip

  13. 13. Hatchery Surplus feeds People and Ecosystem
  14. 14. Nisqually Stock Management: Why Change? Nisqually Natural Spawning Escapement Approx. 70% pHOS will not lead to Local Adaptation
  15. 15. How do we re-establish a wild Nisqually stock while still providing harvestable numbers of hatchery fish?
  16. 16. Utilize Mainstem Weir to Control Hatchery Composition on Spawning Grounds
  17. 17. Fish Auger
  18. 18. Old Technology
  19. 19. Modify Broodstock Management to Support Local Adaptation <ul><li>Local adaptation requires low pHOS, must have multiple generations of natural x natural spawning </li></ul><ul><li>Large Nisqually hatchery program very important for tribal commercial and sport harvest </li></ul><ul><li>Will not be able to exclude all HOR and meet effective pHOS target (10%) when hatchery program > natural run </li></ul>Approach: Initiate hatchery program where the natural environment drives adaptation, reducing the impact of hatchery spawners on natural fitness
  20. 20. Future Broodstock Management Key Elements <ul><li>Develop an integrated hatchery program to generate broodstock to support the stepping-stone harvest program and to provide a safety net in years of critically low adult abundance </li></ul><ul><ul><li>Total brood stock: 420 adults </li></ul></ul><ul><ul><li>pNOB (percent natural-origin adults in broodstock): 25% </li></ul></ul><ul><ul><li>(75 to maximum 105 adults) </li></ul></ul><ul><ul><li>Smolt release: 400,000 to 600,000 fish </li></ul></ul><ul><ul><li>Release location: Kalama Creek initially and then move to Clear Creek after retrofit </li></ul></ul><ul><ul><li>Marking: 100% coded wire tags (CWT), 75,000 CWT/adipose fin clip for double-index tagging program, the remainder no adipose fin clip </li></ul></ul>
  21. 21. Future Broodstock Management Key Elements (cont.) <ul><li>Develop a stepping-stone hatchery program to provide harvest using brood stock collected from the integrated program return </li></ul><ul><ul><li>Broodstock: 2,300 adults taken from integrated hatchery return </li></ul></ul><ul><ul><li>Smolt release: 3.4 to maximum 3.6 million, dependent on size of integrated program </li></ul></ul><ul><ul><li>Release location: Clear Creek </li></ul></ul><ul><ul><li>Marking: 100% adipose fin clip, 100,000 CWT/adipose fin clip </li></ul></ul>
  22. 22. Future Broodstock Management Key Elements (cont.) <ul><li>Operate an adult weir at river mile (RM) 12.3 in the Nisqually River during fall Chinook management season (early July to October 30 ) </li></ul><ul><ul><li>Monitoring: count escapement at weir and number unmarked Chinook passed upstream of weir </li></ul></ul><ul><ul><li>Escapement composition: exclude all hatchery-origin adults from escapement upstream of weir </li></ul></ul><ul><ul><li>Broodstock collection: collect up to 105 unmarked adults at weir for the integrated hatchery program </li></ul></ul>
