PIT Tags for Fish Reliable Identification for Aquatic Research and Aquaculture

PIT tags for fish are small, biocompatible RFID microchips that provide permanent and unique identification for individual fish.
They are widely used in fisheries, aquaculture farms, and ecological research programs to monitor growth, migration, and survival rates.
At DO RFID TAG Manufacturer, we produce high-quality PIT tags for fish that comply with ISO 11784/11785 standards and work with all major PIT tag readers and antenna systems.

How PIT Tags Work in Fish

A PIT tag (Passive Integrated Transponder) is a small glass-encapsulated microchip implanted under the skin or in the body cavity of a fish.
Each tag carries a unique ID number that can be detected by a PIT tag reader when the fish swims through an antenna or is manually scanned.

The tag does not require a battery. Instead, it draws energy from the electromagnetic field of the reader.
This passive design ensures long-term operation, making it ideal for tracking fish over several years with minimal maintenance.

Applications of PIT Tags in Fish Research

1. Migration Tracking:
   Researchers can track fish movement through rivers or dams using antenna arrays that record each tag’s ID when the fish passes by.

2. Population Monitoring:
   PIT tags help record recapture rates and estimate survival and reproduction of different species.

3. Aquaculture Management:
   Fish farms use PIT tags for individual identification, breeding programs, and inventory tracking.

4. Environmental Studies:
   Used in ecological monitoring projects to assess the impact of temperature, pollution, or habitat change on fish populations.

Whether you are working on a government research project or managing a private hatchery, PIT tagging provides accurate, long-term identification data.

Common Sizes and Tagging Options

We offer different PIT tag sizes for fish of various species and body sizes:

• 8 mm PIT Tag: Ideal for small fish, juveniles, and amphibians.

• 12 mm PIT Tag: The most common choice for adult fish like trout, salmon, and carp.

• Custom Sizes: Optional 9 mm, 10 mm, or special material encapsulation for research-specific needs.

All fish PIT tags are hermetically sealed, waterproof, and pressure-resistant, ensuring reliable performance in fresh or saltwater environments.

PIT Tagging Equipment for Fish

To implant PIT tags efficiently and safely, a complete tagging system includes:

• PIT Tag Injector (Tag Gun): Used to insert the tag under the fish’s skin or into the body cavity.

• PIT Tag Reader / Scanner: Reads the unique tag number for identification.

• Data Collection System: Stores and analyzes tag readings for research or management use.

DO RFID TAG Manufacturer provides compatible readers, injectors, and accessories to build a full fish tagging solution.

Advantages of Using PIT Tags for Fish Tracking

• Accurate and permanent identification for each fish.

• Long service life with no power or maintenance required.

• Compatible with automated detection systems and field readers.

• Safe for fish; bioglass material is non-toxic and biologically inert.

• Cost-effective solution for both small and large-scale tagging projects.
