Conventional 11.5mm × 2.1mm FDX-A implantable PIT tag for aquaculture broodstock, larger fish, and fisheries research — supplied as a sterile 10-pack with single-use needles. Best read range of the ID100 range.

About this product

The Trovan ID100C is the conventional-sized FDX-A microchip / PIT tag — 11.5mm long and 2.1mm in diameter. It's the standard chip used in Australian aquaculture broodstock programs, larger fish, and fisheries research where the Midi (8mm × 1.4mm) isn't required and best read range is preferred.

Ideal for

• Adult broodstock fish — barramundi, salmon, trout, kingfish, jewfish, native bass
• Selective breeding programs — adult breeding stock requiring permanent ID across multi-year programs
• Hatchery raceway and swim-through monitoring — best read range at fixed monitoring stations
• Pearl farming — adult oyster identification for breeding programs
• Fisheries mark-recapture studies — adult fish in rivers, lakes, and aquaculture ponds
• Aquaculture research where individual fish identification needs to last 15+ years

Why Trovan FDX-A for aquaculture

The Trovan Unique ID100 (FDX-A) protocol is the most widely-used implantable RFID system in Australian aquaculture and fisheries research. FDX-A tags work with the full range of Trovan reading systems — handheld scanners, swim-through tunnel antennas, frame-type readers (e.g. AquaPocket), and submersible creek-bed receivers — whereas ISO FDX-B tags often can't be read reliably (or at all) by these systems.

Note: Trovan FDX-A microchips are NOT suitable for companion dogs, cats or horses in Australia — Australian legislation requires ISO FDX-B for companion animals. For broodstock, hatchery and research animals, FDX-A remains the industry standard.

Format and supply

Each microchip is pre-loaded into an individual single-use sterile needle. Implantation uses the re-usable Trovan IM200 syringe implanter (sold separately). Each 10-pack includes 6 adhesive labels per chip.
