BackgroundBackground

• 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

Recommendations to Recommendations to Improve Coordination of Improve Coordination of

Tagging ProjectsTagging Projects

FWP projects should include a tagging coordination plan

A web-based information network should be developed

Establish an expert tagging committee

Recommendations to Recommendations to Improve Cost-Effectiveness Improve Cost-Effectiveness

of Tagging Projectsof 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

Recommendations to Recommendations to Encourage Development and Encourage Development and

Use of Use of Innovative Tagging Innovative Tagging

TechnologiesTechnologies

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

Recommendations Related to Recommendations Related to Specific Tagging Specific Tagging Technologies-ITechnologies-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

Recommendations Related to Recommendations Related to Specific Tagging Specific Tagging Technologies-IITechnologies-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

10

Recommendations Related to Recommendations Related to Specific Tagging Specific Tagging Technologies-IIITechnologies-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

Recommendations to Close Recommendations to Close Gaps in Capacity to Collect Gaps in Capacity to Collect

Life History DataLife 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

Recommendations to Close Recommendations to Close Gaps in Capacity to Collect Gaps in Capacity to Collect

Life History DataLife 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

13

Recommendations to Recommendations to Improve Compatibility of Improve Compatibility of

ResultsResults

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
