The Coded-Wire Tag Program:
Regional Overview
![Page 2: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/2.jpg)
Coded Wire Tags: Tiny Tool for Stock Identification
– Stainless steel micro-tag– Introduced in late 1960s – Replaced fin clips for stock id – Placed in nasal cartilage– Originally binary coding scheme– Adipose clip used ~ 3 decades as
external flag for tagged fish– Present: Use of electronic detection:
Ad clip now flag for hatchery fish

Major Advantages of CWTs
– Small size (0.25 x 1.1 mm)– Ease of application– Very low tag loss– Vast number of codes– Low cost (14 cents/tag applied)– Biological compatibility– Very minimal impact on
survival

CWT Quality Today
• Tag 16/58/09 made 11 April 2002
![Page 6: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/6.jpg)
Types of CWT Marking Studies1) Management Objectives
– Stock contribution (fisheries viewpoint); Harvest allocation; Survival trends; Escapement
2) Hatchery and Wildstock Evaluation– Stock contribution to the various fisheries
coastwide; Straying; Age composition, etc.
3) Experimental Comparisons– Diets, release sites, time of release, density, etc
4) Habitat Evaluation
![Page 7: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/7.jpg)
Relevance of CWT Information to the NWPPC’s Fish & Wildlife Program
• The CWT is the stock ID tool used coastwide for evaluating survival rates and status of salmonid stocks.
• It serves a wide variety of F&W Program purposes, including: – Hatchery monitoring and evaluation– Adult and juvenile migration patterns– Evaluate and monitor harvest
• Coastwide harvest management closely intertwined with the mission of the F&W Program; and is critical to protecting Columbia River stocks in trouble.
• Federal ESA depends on CWT marked hatchery fish as indicators for wild listed stocks.

Scale of Coastwide CWT Tagging Program
• 50 million tagged smolts released coastwide each year at a cost of ~$7.5 million
• Over 1,200 new codes involving hundreds of studies
• Chinook tagging levels are highest at 39 million; Coho levels at 9-10 million
• 54 federal, state and tribal fisheries agencies plus private entities now tag fish
![Page 15: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/15.jpg)
Principal Tagging Facilities
• Tagging programs are carried out at over 330 federal, state, tribal, and private hatcheries and rearing facilities on the west coast, including Canada
• Wild stocks also captured and tagged at numerous sites
![Page 16: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/16.jpg)

Scale of CWT Tagging Programin the Columbia Basin
• 18-20 million of the 50 million chinook and coho tagged annually come from the Columbia Basin
• Of those, ~6-7 million tags were directly funded by BPA in 2003
• On a coastwide basis, BPA funds an estimated 13% of the 50 million tags released annually
![Page 19: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/19.jpg)
BPA Funded CWT Tagging Programs in the Columbia Basin
• Prior to 1989, many hatcheries released chinook and coho without tagged groups
• In 1989 BPA began to fund tagging the “Missing Production” groups at ODFW, WDFW and USFWS hatcheries
• In 2000, projects renamed “Annual Stock Assessment - CWT” to avoid former confusing name
![Page 20: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/20.jpg)

Ongoing Challenges for the Clackamas Tag Recovery Lab
• The processed heads represent samples taken from fisheries, spawning grounds, and hatchery rack returns over multiple years (e.g. 2005 work covered 2002-2005 samples)
• Level funding, staff reductions and large escapements have overwhelmed the capacity of the lab to keep abreast of the work.
• This has forced prioritizing CWT processing:– In-season management needs met first– Fishery evaluation needs met second– Hatchery returns typically met last unless specific
needs exist
![Page 36: The Coded-Wire Tag Program: Regional Overview. Coded Wire Tags: Tiny Tool for Stock Identification –Stainless steel micro-tag –Introduced in late 1960s.](https://reader035.fdocuments.us/reader035/viewer/2022062511/5514e9bb550346a80c8b4a43/html5/thumbnails/36.jpg)

The Regional Mark Information System (RMIS)
• CWT data are forwarded to the Mark Center where it is loaded and validated against an extensive set of checks
• Once validated, the data are moved into an online relational database (Oracle) that the public can access by Internet
• Data is accessible in either PSC exchange format, or various summary reports
