| CWT Tag Formats
The decimal coding (etching) allows for either batch or individual identification. Batch codes, identifying a group of animals sharing one or more characteristic, are most commonly used for fisheries management purposes. Standard CWT have batch coding; the same code is repeated over a specific length of wire. Sequential CWT are designed to identify individuals or small groups; the code advances over a specific length of wire. The use of these sequential tags is somewhat more complex in requiring the saving or "archiving" of a CWT before and after the implanted tag or tags. NMT produces five formats of CWT. Download the reading instructions for a complete description of each format.
