NMT LogoWe specialize in fish tags, and invite you to explore their applications to your project. Our tags include Coded Wire Tags (CWT), Visible Implant Elastomer (VIE) and Visible Implant Alpha (VI Alpha). They were first developed as fish tags, but are now applied to a wide range of fish, crustaceans, cephalopods, reptiles, amphibians and other animals throughout the world. Projects range from identifying a few animals to coastwide application. In the Pacific NW, over 2 billion juvenile salmon have been tagged with Coded Wire Tags and this method continues to be critical to managing Pacific Salmon. The vast scope of this tagging program inspired the development of AutoFish System for clipping and tagging millions of fish per year.
