trace-back.
NASCO Marking Workshop December 6-8, 2004by Douglas McCartney
Identify UK Limited
Overview
• Introductions
• Traditional approaches to salmon ID
• Why use implantable RFID?
• What is electronic identification and how does it work?
• How is the transponder applied?
• Criteria for selecting a microchip system
About Trovan, Ltd.
• Privately held and funded UK corporation.

identified.
• Customers include leading commercial operators and government agencies in Europe, South America, Asia, Australasia, and North America.
Traditional approaches to fish ID
• Coded wire tags
• Fin clipping
• Chemical markers
Why use implantable RFID?
• Non-contact, non-line of sight. Code can be read through animal tissue, in cloudy or turgid water, irrespective of orientation.
• Reliable. Over fifteen years continuous use in salmon fisheries.
• Unlimited tag lifespan. Code does not degrade over time.
• Permanent, non-removable ID.
• Implanted RFID does not impact fish mobility or alter fish behaviour.
• Automated data capture: Eliminates transcription errors.
How RFID works
Transponders

RFID in action
How is the transponder applied?Implantation
• Take fish off their feed 48 hours prior to tagging.
• Sterilize transponders in medical grade alcohol.
• Using scalpel or similar device, nick body wall just off mid-ventral line, behind pectoral fin.
• Insert tag with finger.

Criteria for selecting an implantable RFID system
• Can I read the tag? (1) Reading range
>20 cm for portable reader; Swim-by panel readers. (2) Read area (the larger the better) (3) Read speed.
• Automation of operations.
• Data integrity Unique numbers to guarantee positive identification.
• Quality and product reliability (1) Microchip design reliability: minimizing the number of components. (2) Manufactured to ISO 9001 standard.
TROVAN system advantages--all tags are not created equal.
• Performance (1) Reading range
>24 cm for portable reader. (2) Swim-by and pass-by panel readers. (3) Top read speed.
• Dedicated readers designed for fisheries applications.
• Over 550 billion unique ID numbers through patent protection.
• Quality and product reliability (1) Microchip design reliability: minimizing the number of components. (2) Manufactured to ISO 9001 standard.
