  1. ODFW Monitoring & Evaluation in Northeast Oregon PIT Tag Technology

  2. Life Cycle Comparative Survival Profile(BY 2000-05 adult -08 smolts) Eggs 3700 Summer Parr Minam = 1210(32.7%) Catherine = 902(24.4%) Adult Spawners – SAR’s Minam=3.8(2.5% & 1.4%) Catherine=0.8(1.1% & 0.5%) John Day=3.1(4.5% & 3.3%) Tributary Smolts Egg-SmoltParr-Smolt Minam=278(7.5%) Minam=23.0% Catherine=175(4.7%) Catherine=19.4% John Day=93(2.5%) Trib to Adult 1st Dam Smolts Minam=156(56.0%) Catherine =73(41.8%) John Day=68(73.5%) 1st Dam to Adult Jacks Ocean

  3. Wild Spring Chinook Life History Evaluation • Population smolt abundance • John Day reference populations • Grande Ronde listed populations • Freshwater productivity • Juvenile migration survival • SAR – ocean survival • Fishery predictions

  4. Ocean Survival (SAR)

  5. John Day River Wild Spring Chinook Freshwater Productivity

  6. John Day River Adult Chinook Fishery Predictions

  7. Hatchery Chinook Adults: Bonneville Dam to “home”Return Year 2003-2011 Imnaha River • 20,000 PIT tags • 11-30% of releases tagged Lostine River • 6,400 – 16,000 PIT tags • 3-15% of releases tagged R-squared = 0.899 R-squared = 0.856

  8. Juvenile Survival from Catherine Creek to Lower Granite Dam Lower Granite Dam Snake Washington River Oregon River Ronde 40 Kilometers Grande Wallowa Grande Ronde Valley River Lostine N River Catherine Creek

  9. Reach Specific Survival from Catherine Creek to Lower Granite Dam

  10. Heron Predation of Hatchery Chinook Smolts

  11. Mid-Columbia Steelhead Evaluation • Population smolt abundance • Freshwater productivity • Juvenile migration survival • SAR – ocean survival • Adult spawner migration • Hatchery stray rates

  12. Steelhead Run Timing Cumulative Counts @ Bonneville

  13. John Day River Wild Adult Steelhead

  14. John Day River Adult Steelhead In-stream PIT detections

  15. McDonald Ford Antenna

  16. Adult Steelhead Detections of Transport Study Groups2007-08 & 2008-2009 Run Years

  17. CSS Hatchery Adult Steelhead Passage Between Bonneville Dam and Lower Granite Dam z-test P < 0.001

  18. Stray Rates Into the John Day for Transported and In-River Migrants % Run Year

  19. Wallowa Stock Steelhead Fishery Evaluation Troy Wallowa Hatchery Joseph La Grande Union

  20. Objectives • Create a new hatchery line from Wallowa stock returning to Grande Ronde in autumn. • Autumn Line may stray less and improve the autumn fishery. • Compare performance of Autumn Line with the standard Wallowa Stock. • Is smolt outmigration survival similar? • Does the Autumn Line return earlier? • Are smolt-to-adult survival rates similar? • Does the Autumn Line stray at a lower rate?

  23. PIT Tag TechnologyWhat have we learned? • VSP measures • Life stage survival • Freshwater productivity • Ocean survival • Hatchery fraction • Life history designation • Management solutions • In season fishery predictions • Developed a new hatchery stock • Hatchery strays • Migration corridor contributes significant mortality • Juveniles • Adult steelhead wandering • Freshwater survival is still limiting • John Day vs. Grande Ronde Chinook
