2 Harvest Management Annual Cycle Egg Alevin Post Season Pre-Season Spawn Adult In-Season Fishery Agreement & Permitting Fry Ocean Adult Smolt

3 Harvest Management Annual Cycle Pre-Season Forecasts NOF, PFMC, PSC Policy Negotiations & Agreement Fishery Schedules permitted In-Season Enforcement Fisheries Monitoring and ISUs Post-Season Final Catch data Review Fisheries Performance of Management Objectives

4 Stillaguamish Forecasts; technical agreement WDFW predicts Chum & Pink STNRD predicts Chinook & Coho Spawning Ground Sampling Data Bio-data CWT & Scale recoveries Escapement Estimates Hatchery Sampling Data Fecundity/Spawning Release Data Smolt Trap CPUE

5 2017 Chum Forecast: 5,614 Odd Year Escapement Goal: 13,100

6 2017 Pink Forecast: 40,205 Escapement Goal: 155,000

7 Chinook Forecast uses the Environmental Model to Predict Adult Returns (EMPAR); utilizing full life history data, multiple linear regressions averaged for best fit.

8 Exploitation Rate: Low Abundance Threshold: 700 NOR Critical ER <15% SUS

9 Coho forecast using previous method of regressing run size against an adjusted CPUE did not support normality, through discussion co-managers agreed to using 2016 terminal escapement multiplied by ratio of 2016/2015 CPUE.

10 3 levels of management: Normal, escapement >20,000 ER < 50% Low, escapement >10,000 and <20,000 ER < 35% Critical, escapement <10,000 ER <10%

11 North of Falcon Co-Manager discussions; WDFW & Treaty Tribes Policy Agreement on forecasts; Harvest Impacts proposed to Comanagers that account for mortalities during all fisheries. Boldt Decision 50% of harvestable share Share defined by species specific Management Objectives: Chinook: Low Abundance Threshold, critical status, total stock ER 25%, SUS 15% of total ER Coho: ERs based on forecast; critical 10% ER Pink: escapement 155,000, anything above that split 50/50 Chum: odd year escapement 13,100, anything above that split 50/50

12 Fishery Planning Considerations Types of Fisheries Commercial treaty or non-treaty economic type net fishery, catch is sold & monetized Recreational non-treaty sport fishery, individual catch for take home, not sold. Ceremonial & Subsistence treaty fishery for cultural traditions, ceremonial utilizes designated fishers only, subsistence is for all licensed tribal members to individual catch for take home, not sold ( Take Home ). Test Fishery treaty or non-treaty sampling fishery to gathering scientific information, not included as allocated catch within the harvestable shares.

13 Fishery Planning Considerations Types of Areas Marine Area = mixed stock fishing, multiple stocks are impacted in fishery Terminal Area = specific stock fishing, only one stock is impacted in fishery Types of Retention Non Selective Fishing : all catch regardless of mark is retained. Mark Selective Fishing: target hatchery raised fish, only marked fished retained. Non-Retention : all catch release, no take home.

14 North of Falcon Co-Manager discussions; WDFW & Treaty Tribes Model Runs: FRAM & TAMM modeling to assess risk in fisheries Technical Review: Ensure Management Objectives are being met Policy Negotiations (Repeat as necessary until agreement) Fishery Policy Agreement List of Agreed Fisheries (LOAF) Fishery Package submitted to NOAA ESA permitting (section 7 or section 4(d)) Regulations issued by fishery

15 Stillaguamish River 2017 Fishery Schedule Non-Treaty Main Stem, Boulder, Canyon, Pilchuck, Squire: CLOSED North Fork, Mouth to Swede Heaven: 1. June 3 rd July 31 st Fly Fishing Only, release all fish except 2 hatchery steelhead may be retained. 2. August 1 st November 30 th, CLOSED 3. December 1 st January 31 st Fly Fishing Only, French Creek to Swede Heaven Only, release all fish except 2 hatchery steelhead may be retained. Swede Heaven to North Fork Falls: CLOSED South Fork, Mountain Loop Highway upstream: 1. June 3 rd Sept 4 th, open for gamefish, selective gear rules, statewide min size/daily limits (2 trout). 2. Sept 5 th Jan 31 st, CLOSED South Fork, Mountain Loop Highway downstream: CLOSED Areas above Anadromous barriers, May 27 th Oct 31 st. Statewide min size/daily limits.

16 Stillaguamish River 2017 Fishery Schedule Treaty Mainstem; Mouth of Hatt Slough to Danielson Hole 1. Chinook, Ceremonial Only 2. Pink, Ceremonial & Subsistence 3. Coho, Ceremonial Only 4. Chum, Ceremonial & Subsistence 5. Steelhead, TBD in October, dependent on run size.

17 In-Season Fishery Management Monitoring of catch and impacts to not exceed management objectives Closures and reduced fishing areas prevent ISU on Stillaguamish Stocks

18 In-Season Enforcement DFW and Tribal Enforcement uphold all fishing regulations, as poaching impacts salmonid populations negatively.

19 Post Season Management Stock Specific and ESU Management Objectives Fishery Catch Data compiled: Exploitation Rates Reviewed Spawning Ground/Hatchery Rack Data compiled: Escapement from fisheries to River reviewed Backwards FRAM Run Reconstruction: Stock Abundance assessment PSC Technical Committee Reports: Fishery Performance ESU Recovery Goals assessed
