  1. Management Implications of ISAB Tagging Report#2009-1 Council MeetingJune 9, 2009Whitefish, Montana

  2. Items for Discussion • Background of Review • Report Recommendations • Coordination • Cost-effectiveness • Innovative Technologies • Close data collection gaps • Compatibility of results • Management implications 2

  3. Background • ISRP suggested a tagging review in 2006 following FY 2007-09 project review cycle • Review timely because tagging data used for management decisions • In July 2007, Council requested a science review of tagging technologies in basin • Council posed 6 specific questions for science panels to address during review 3

  4. Recommendations to Improve Coordination of Tagging Projects • FWP projects should include a tagging coordination plan • A web-based information network should be developed • Establish an expert tagging committee 4

  5. Recommendations to Improve Cost-Effectiveness of Tagging Projects • Develop a FWP monitoring/tagging framework for anadromous fish – already underway • Project proposals should include a review of costs of different tagging technologies 5

  6. Recommendations to Encourage Development and Use of Innovative Tagging Technologies • Best strategy is to continue to develop several tag technologies that can be used in combination to address management needs • Develop or improve surgical techniques for tag insertion or external attachment to reduce tagging effects 6

  7. Recommendations Related to Specific Tagging Technologies-I • Continue to develop technologies for genetic markers for salmon and stlhd. • Further development of otolith thermal marking as an alternative to CWTs • Develop and install instream PIT-tag detectors in key tributaries & at dams 7

  8. Pictures of Various Tags 8

  9. Recommendations Related to Specific Tagging Technologies-II • Continue to reduce size of acoustic tag while increasing battery life • Develop an acoustic receiver system to track fish tagged with all types of acoustic tags • Continue to develop receivers that can be remotely downloaded • Continue to evaluate long-term effects of acoustic tags on salmon behavior and survival 9

  10. Recommendations Related to Specific Tagging Technologies-III • Develop smaller radio tag transmitters with longer battery life and no antenna • Develop and use underwater antennas in depths greater than 9 meters (~30 ft.) • Increase number of unique tag codes • Develop sensor technology for juvenile salmon radio tags • Use radio tags with PIT tags to address management needs in freshwater 10

  11. Recommendations to Close Gaps in Capacity to Collect Life History Data • Employ PIT-tag detection capability in key tributaries • Determine whether hatchery fish can be used as surrogates for wild fish • Tag/mark 100% of CRB hatchery fish 11

  12. Recommendations to Close Gaps in Capacity to Collect Life History Data • All tagging projects should document statistical validity of tagging and tag recovery rates • Implement the reproductive & long-term M&E projects identified by AHSWG • Evaluate long-term effects of various tags on salmon behavior and survival, incl. tag shedding 12

  13. Recommendations to Improve Compatibility of Results • All FWP projects with ocean port and lower river sampling for CWT recovery should address tagging and tag recovery issues • Determine whether vital biological rates using data from tagged hatchery fish are representative of wild fish 13

  14. Management Implications for Next FWP Project Review Cycle-I • All FWP projects involving tagging should include a coordination plan • A web-based information network should be developed for all fish tagging projects • All FWP projects with ocean port and lower river sampling for CWT recovery should address tagging and tag recovery issues 14

  15. Management Implications for Next FWP Project Review Cycle-II • All tagging projects should document statistical validity of tagging and tag recovery rates • All FWP project proposals should include a review of application and costs of different tagging technologies • Region should establish an expert tagging/marking committee 15
