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.

RFID in action
![Page 14: RFID: Reliable identification for salmon trace-back. NASCO Marking Workshop December 6-8, 2004 by Douglas McCartney Identify UK Limited.](https://reader035.fdocuments.us/reader035/viewer/2022062618/55142b53550346e7488b5cc4/html5/thumbnails/14.jpg)
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.
