1 SELECT AREA FISHERY EVALUATION BPA Project # CEDC, ODFW, WDFW

2 Project Goal: Develop and enhance known stock fisheries in LCR while protecting depressed wild stocks Project Background: Research ( ) Investigated 9 potential sites Test fishing for stock composition Determined rearing strategies Expansion/Introduction ( ) Expanded Youngs Bay production Established fisheries in 5 new sites Implementation ( ) Expand species, capacity, and releases in all areas Overview

3 Net Pen Sites

4 Rearing Net Pen Sites Youngs Bay (76 pens) COH, CHS, CHF-SAB Tongue Point (37 pens) COH Blind Slough (15 pens) COH, CHS Deep River (36 pens) COH, CHS Steamboat Slough (16 pens) COH Hatcheries Big Cr, CEDC, Cowlitz R, Eagle Cr, Elochoman R, Gnat Cr, Grays R, Klaskanine, Oxbow, Sandy, Willamette

5 Releases Past Releases COH 2-4 million CHS 1 million CHF-SAB fluctuating 2002 Releases 3.8 million COH 1.0 million CHS 1.6 million CHF-SAB

6 Commercial Fisheries Expanded and stable commercial opportunities Expanded market window Targets local stocks Minimal ESU impacts Minimal handle of incidental species

7 Ex-Vessel Values of Select Area Spring Fisheries,

8 Upriver Spring Chinook Impact Rates in Select Area Fisheries,

9 Recreational Fisheries SAFE releases contribute to ocean and mainstem fisheries Fisheries developing in SAFE areas Open year-round Virtually no impacts on non- target species Quality fish and fishery

10 Experiments Rearing & release experiments Time and size of release Acclimation & over-winter rearing Rearing density Winter dormancy feeding Subsurface feeding Avian avoidance releases Release location

11 Project Monitoring Commercial Landings Catch sampling Stock composition Local vs. non-local ESA impacts Recreational Catch and effort estimates Stock composition Rearing studies Smolt and adult survival rates Water quality Physio-chemical Temp, pH, DO, etc. Benthic Invertebrates/Substrate

12 Select Area Fisheries Evaluation Select Area Fishery Benefits : Known stock commercial harvest opportunities Supplements existing recreational fisheries and creates new opportunities Fisheries managed within ESA guidelines Minimal impacts on non-target species High survival rates Fisheries called for in NWPPC F&W Program and 2001 BO Fisheries approved by Columbia River Compact

13 Select Area Fisheries Evaluation Goals for : Maintain species diversity Increase production of high value species Expand to full production at some sites Enhance SAFE fisheries at other sites Investigate new areas, rearing strategies, and harvest methods Continue monitoring efforts

14 Select Area Fisheries Evaluation Plans for : Full Production: Spring Chinook Youngs Bay and Blind Slough Coho Youngs Bay, Tongue Point, Blind Slough, and Deep River Continued Research: Spring Chinook Deep River and Steamboat Slough Investigate homing enhancement at Tongue Point Coho Steamboat Slough Fall Chinook (SAB) Youngs Bay Achieve broodstock escapement needs

15 Actual and potential ex-vessel values of spring select area fisheries ActualPredicted Predictions based an average adult returns to Oregon and Washington SAFE sites from a combined 3,600,000 CHS releases of 2004 brood, 15# average adult weight and $2.50/pound ex-vessel value
