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