More about Coded Wire Tags

We specialize in fish tags, and invite you to explore their applications to your project. Managers and scientists use fish tags to learn about how fish grow, who catches them, where they go, and how long they live, for example.

NMT LogoOur tags include Coded Wire Tags (CWT), Visible Implant Elastomer (VIE) and Visible Implant Alpha (VI Alpha). They were first developed for salmon, but are now used worldwide with a wide range of fish species, crustaceans, cephalopods, reptiles, amphibians and other animals throughout the world. Projects range from identifying a few animals in the lab to coastwide programs. In the Pacific NW, over 2 billion juvenile salmon have been tagged with Coded Wire Tags. This vast program inspired the development of AutoFish System for clipping and tagging millions of fish per year.
