SELECT AREA FISHERY EVALUATION
BPA Project # 199306000
CEDC, ODFW, WDFW
Project Goal: Develop and enhance known stock fisheries in LCR while protecting depressed wild stocks
Project Background: Research (1994-1995)
Investigated 9 potential sites Test fishing for stock composition Determined rearing strategies
Expansion/Introduction (1996-1998) Expanded Young’s Bay production Established fisheries in 5 new sites
Implementation (1999-2003)• Expand species, capacity, and releases in all areas

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
Select Area Fisheries Evaluation
Goals for 2003-2007: 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
Select Area Fisheries Evaluation
Plans for 2003-2007: Full Production:
Spring Chinook Youngs Bay and Blind Slough
Coho Young’s 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) Young’s Bay Achieve broodstock escapement needs
