10 Fisheries Terms Anadromy (Anadromous) Fish move from saltwater to freshwater to spawn as adults. Smolts Out-migrating juvenile salmonids that have undergone physiological changes to prepare them for life in saltwater Silvery appearance Black banding

11 Fisheries Terms NOR Natural Origin Recruits HOR Hatchery Origin Recruits phos proportion Hatchery Origin Spawners pnob proportion Natural Origin Brood PNI proportion Natural Influence = pnob/(phos+pnob)

17 Cowlitz Salmon Hatchery Purposes of Hatcheries Replace Production from Lost Habitat Sustainable Fisheries Genetic Bank Cowlitz Trout Hatchery

18 Cowlitz Falls Dam 1994/1996

19 Legal Licensing and ESA Mayfield and Mossyrock Dams (Cowlitz River Project- FERC # 2016) Tacoma Power Cowlitz Falls Dam (FERC # 2833) Lewis County PUD w/bpa Power Purchase NMFS ESA Section 7 Biological Opinions Cowlitz River Project (2004) Cowlitz Falls Dam (2009)

20 Cowlitz River ESA Listed Populations Lower Columbia River, Threatened Winter Steelhead Chinook (spring and fall) Coho Chum 2005 Eulachon

21 Tacoma Power Settlement Agreement 2000 Focus on Recovery of Natural Populations Meet Fisheries Obligations by: Provide Effective Juvenile and Adult Passage o 95% Fish Passage Survival (75% min with BAT) o 95% FPS Mayfield Dam Improve Habitat Maintain Hatchery Production Replace Unavoidable Losses Sustainable Fisheries

22 More Plans Fisheries and Hatcheries Management Plan 2006, 2011 update, update Monitoring and Evaluation Annual Project Review to set Hatchery Production LCFRB/NOAA Recovery Plan WDFW Fisheries and Hatchery Reform Policy Hatchery Scientific Review Group guidelines

23 HSRG Guidelines Fit Hatchery Production to Natural Population Population Type Integrated or Segregated Primary, Contributing, Stabilizing HSRG Rule Sets Natural Population Abundance This is what we estimate, Here is where data is used for management!

24 Population Recovery Designations Primary PNI>0.67, phos<5% or phos,pnob/2 Contributing PNI>0.60, phos <10% or pnob Stabilizing phos

25 PNI Natural Environment Hatchery Environment

26 Hatchery Production must fit with Size of Natural Population Size of Natural Population Size of Hatchery Program

27 How To Increase Natural Population? Recolonize Habitat Restore Passage (e.g. Upper Cowlitz) Improve Passage (e.g. Tilton River) Remove Barriers (e.g. Culverts) Improve Habitat Reduce Harvest Improve Fitness/Productivity
