PIT Tag Gun / Injector for Salmon & Trout

Reliable PIT tag implantation starts with selecting the right injector and needle. Whether you’re tagging juvenile trout in a hatchery or adult salmon migrating through river systems, a proper PIT tag injector helps reduce tissue damage, improve healing, and ensure consistent tag placement in the peritoneal cavity.

DO RFID TAG Manufacturer provides professional-grade PIT tag guns and sterile stainless-steel needles, designed to match all common PIT tag sizes—from small 2×8 mm FDX-B tags to larger HDX tags used in adult fish.

Why the Injector Matters for Fish Tagging Programs

A PIT tag is only as effective as the quality of its implantation. Improper tools can lead to:

• Higher tag loss rates

• Delayed healing

• Increased stress during handling

• Shorter long-term survival

Our injectors are built for smooth insertion, precise control, and compatibility with all standard PIT tag sizes used in salmonid monitoring programs.

Compatible Needle Sizes for Salmon & Trout

Choosing the correct needle size is essential for minimizing injury and ensuring proper placement.
Below are the industry-standard needle sizes used worldwide for salmon and trout PIT tagging:

For Small Juvenile Trout / Juvenile Salmon

1.25 mm Inner Diameter Needles
Suitable for:

• 1.4×8 mm

• 1.5×8 mm

• 2×8 mm FDX-B tags

Benefits:

• Small entry wound

• Ideal for hatchery fish

• Faster recovery after tagging

For Larger Juveniles or Small Adults

1.4–1.6 mm Inner Diameter Needles
Suitable for:

• 2×10 mm

• 2×12 mm FDX-B / HDX tags

For Large Adult Salmon / Trout

2.0 mm Needles
Suitable for:

• 3×13 mm

• 3.85×23 mm HDX / FDX-B tags

These needles are compatible with the injector bodies we supply, making it easy to switch sizes depending on your project.

Injector Types Available

DO RFID TAG Manufacturer supplies two professional injector styles:

1. Stainless-Steel Manual Injector (Most Common)

• Durable and precise

• Easy to sterilize

• Works with all needle sizes

• Preferred for hatcheries and small-scale tagging

2. Semi-Automatic PIT Tag Injector

• Faster operation for large tagging batches

• Consistent insertion depth

• Ideal for university labs and hatcheries tagging thousands of fish per season

How Our Injector Improves Tagging Success

• Smooth plunger reduces tissue tearing

• Locking needle design prevents tag “bounce back”

• Compatible with all DO RFID PIT tags

• Standardized depth alignment for consistent implantation

• Medical-grade stainless steel for maximum hygiene

We also provide pre-sterilized needle packs for high-throughput tagging projects.

Sterilization & Handling Guidelines

To maintain low mortality and avoid infection:

1. Sterilize needles with ethanol or autoclave

2. Use fresh gloves for each tagging session

3. Keep PIT tags in sterile packaging until use

4. Avoid touching the tag surface with bare hands

5. Replace needles after tagging ~100–150 fish

Proper tool hygiene is essential for minimizing tag rejection rates.
