Overview
PIT tag readers are essential equipment for identifying and tracking fish carrying FDX-B or HDX PIT tags. A high-performance reader ensures accurate detection, stable decoding, and reliable data collection in hatcheries, rivers, laboratories, and field environments. We manufacture professional PIT tag readers designed for salmon and trout monitoring, migration research, aquaculture management, and wildlife tagging programs. Our product line includes handheld readers, fixed readers, antenna-integrated systems, and OEM reader modules, providing complete solutions for studies of juvenile and adult fish.

Types of PIT Tag Readers

Handheld PIT Tag Readers

Designed for hatchery operations and field sampling.
Ideal for fish measurement, tagging verification, and mobile data collection.

Key features:

• Fast reading of FDX-B and HDX tags

• Lightweight and waterproof housing

• Integrated antenna with strong sensitivity

• USB or Bluetooth data output

• Compatible with 8 mm and 12 mm PIT tags

• High battery performance for field use

Common uses: hatcheries, boat surveys, research trips, mobile PIT-tag verification.

Fixed PIT Tag Readers

Designed for continuous monitoring.
Typically installed in raceways, fish ladders, bypass channels, weirs, and river passages.

Key features:

• 24/7 stable operation

• High decoding sensitivity

• Multi-antenna support

• Anti-interference performance for complex environments

• Long reading distance for large arrays

• Waterproof enclosure for outdoor installation

Applications: migration studies, return monitoring, survival evaluation, behavior tracking.

Antenna-Integrated Readers

A plug-and-play system combining reader + antenna.

• Simplifies installation

• Offers stable read range

• Ideal for hatchery raceways

• Suitable for small river monitoring

This system reduces engineering complexity and ensures compatibility with all DO RFID TAG PIT tags.

OEM Reader Modules

For universities, engineering teams, and research institutions needing customized integration.

OEM capabilities:

• FDX-B or HDX decoding

• UART/TTL/RS232 communication

• Custom reading protocols

• Embedded power control

• Multi-antenna switching

• Firmware customization

This option is ideal for building autonomous or solar-powered PIT detection stations.

Technical Specifications of Our Readers

FDX-B and HDX Compatibility

All readers support ISO 11784/11785.
HDX readers are optimized for high-power pulse detection.
FDX-B readers maintain stable performance with small tags such as 8 mm and 12 mm models.

Reading Distance

Reading distance varies based on tag size, antenna type, and environmental noise.

Typical performance:

• Handheld readers: 5–25 cm (depending on antenna size)

• Integrated systems: 20–80 cm

• Fixed reader + custom antenna: 0.5–2.8 m

• Large river antennas: several meters (project-specific)

Anti-Interference Design

Our PIT tag readers are engineered to maintain stable performance in:

• high-noise hatcheries

• metal-dense facilities

• high-flow river passages

• underwater or semi-submerged installations

Readers use frequency filtering and optimized coil sensitivity to minimize signal loss.

How PIT Tag Readers Are Used in Fisheries Monitoring

1. Hatchery PIT Tagging

• Identify juvenile salmon and trout

• Confirm PIT tag implantation

• Record size, weight, and PIT ID

Readers synchronize with hatchery databases for traceability.

2. Migration Tracking in Rivers

Fixed antennas paired with high-sensitivity readers detect fish as they pass through monitoring points.

Used for:

• Survival estimates

• Migration timing

• Return rates

• Fish ladder usage

3. Aquaculture and Farm Management

Readers help track:

• Feeding cycles

• Growth stages

• Health management

• Inventory and population movement

4. Research Studies

Supported by:

• Universities

• Environmental organizations

• Government biology departments

Readers enable long-term studies for conservation, population modeling, and ecosystem management.

How to Choose the Right PIT Tag Reader

Handheld Reader

Best for:

• Mobile scanning

• Sampling in remote locations

Fixed Reader

Best for:

• Long-term monitoring

• River or hatchery gates

• Automatic detection

Integrated Reader + Antenna

Best for:

• Simple installations

• Hatchery raceways

OEM Module

Best for:

• Custom research systems

• Embedded projects

• Multi-point detection arrays
