PIT Tag Gun Injector for Salmon Trout

Title: PIT Tag Gun / Injector for Salmon & Trout

Introduction

A high-precision PIT tag gun (injector) is essential for accurate implantation in salmon and trout, ensuring clean entry, minimal tissue damage, and maximum retention. For hatcheries, research labs, and fisheries management programs, using a reliable injector directly determines tag performance, survival rates, and data accuracy.
DO RFID TAG offers professional-grade PIT tag guns designed for 1.25×7 mm, 1.4×8 mm, 1.5×8 mm, 2×8 mm, 2×10 mm, 2×12 mm, 3×13 mm and other FDX-B / HDX PIT tag sizes.

Why a High-Quality PIT Tag Injector Matters

1. Cleaner Implantation & Higher Survival Rate

A stable injector ensures the needle enters at a correct angle, reducing muscle tearing and lowering post-implant mortality — especially important for small juvenile salmonids.

2. Consistent Penetration Depth for Accurate Tag Reading

Incorrect depth may cause misreads, weak signal strength, or tag migration. A calibrated gun ensures every PIT tag sits at the same depth beneath the epidermis.

3. Reduce Human Error in Large-Scale Tagging Projects

Hatcheries and field teams often tag thousands of fish daily. A comfortable, easy-trigger injector reduces hand fatigue and ensures consistent implantation speed.

4. Designed for All Fisheries PIT Tag Protocols

Our PIT tag guns follow NOAA, USGS, CDFW, and international tagging guidelines for salmonid monitoring programs.
