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
5
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
6
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
7
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
11
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
12
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
