  15. Focus Groups Questions included: • Reasons for fishing • Fishing sites and seasons • Species eaten and frequency • Preparation methods • Where they get information about fish • Test Delta sign (LULAC only)

  16. EHIB Evaluation of Fishing Activities • Needs Assessments and Fishing Activities Assessments • Focus Groups • DFG Creel Survey • Contra Costa Boater Survey • Delta Angler Survey

  17. DFG Creel Survey • Rivers 1998-2003 • Reservoirs 2000-2006 • Count of shore and boat anglers • Species kept and released • Fish length • Fishing satisfaction

  18. Rivers Sampled 1998-2003 (DFG) • Central Valley Salmon and Steelhead Harvest Monitoring Program • Sacramento River • American River • Feather River • Yuba River

  19. Reservoirs Sampled 2000-2006 (DFG) • Folsom Lake • Jenkinson Lake • New Bullards Bar Reservoir • New Melones Lake • Lake Oroville • Pardee Reservoir • Whiskeytown Lake

  20. Species caught and keptSacramento River below SacramentoDFG Creel Data 2002 • American Shad (>800 kept at rivermile 46) • King Salmon (>60 kept at rivermile 45) • Striped Bass (>50 kept at rivermile 59) • Splittail (>20 kept at rivermile 47) • Steelhead (>15 kept at rivermile 49) • Catfish (15 kept at rivermile 39) • 5 or less carp, sturgeon, sunfish, black bass, rainbow trout, or squawfish kept at any rivermile

  21. EHIB Evaluation of Fishing Activities • Needs Assessments and Fishing Activities Assessments • Focus Groups • DFG Creel Survey • Contra Costa Boater Survey (CALFED) • Delta Angler Survey (CALFED)

  22. Contra Costa Boater Survey • Interviewed 1300 boaters • Fishing was 2nd most popular activity • 50% eat Delta fish • Only 8% once a week or more • Striper (39%), catfish (26%), sturgeon (20%), salmon (15%), black bass (12%) • 49% had heard of advisory

  23. EHIB Evaluation of Fishing Activities • Needs Assessments and Fishing Activities Assessments • Focus Groups • DFG Creel Survey • Contra Costa Boater Survey (CALFED) • Delta Angler Survey (CALFED)

  24. Delta Angler Survey

  25. Delta Angler SurveyOctober-November 2005 • Interviewed 97 anglers • 36% Asian, 25% Black, 24% Hispanic, 12% White • South Delta and San Joaquin River • English, Spanish, Cambodian • Fish consumption patterns • Fishing sites • Advisory awareness

  26. Angler Survey Results • 89% eat sport fish • Striper (72%), catfish (72%), bluegill (49%), largemouth bass (45%), crawdad (20%), carp (12%) • Striped bass fishing sites • 63% Delta • 21% San Luis Reservoir/ Delta Mendota Canal • 17% Other • 63% had heard of advisory

  27. Next Steps • More focus groups • Boaters • Vietnamese • Native Americans • Site visits • Shasta Lake • Sutter Bypass • Rice fields and agriculture canals

  28. How will this information be incorporated into the 2006 sampling plan? • Prioritize sites into “matrix” • Consider: • Where sampled already • Represent each county • Lesser known sites/ illegal fishing • Ethnic groups
