Coded wire tag
A coded wire tag (CWT) is an animal migration tracking device, specifically for tracking fish migration. It consists of a small piece of magnetized wire injected into the snout or cheek of a fish so that it may be tracked for research or fisheries management.
The tags can also assist in studying the diet of birds which have eaten tagged fish.
==Data retrieval==
The CWT is not visible once inside the fish; its presence is detected at close range by using a handheld wand or tunnel type detector that can sense the magnetized metal. A number code unique to either a group of fish or an individual fish is etched into the surface of the CWT, and to read the code the fish is killed first so that the tag can be removed and inspected under a microscope. Upon insertion, information about the fish such as hatching date, release date, location, species, sex, and length are recorded along with the corresponding tag code into a database, so that codes on recovered tags can be matched to information within that database. Coded wire tags have been used to research fish species from over 40 different families.〔Vander Haegen, G., Blankenship, H.L., Knutzen, D., McKenzie, J.R., Parsons, B., Seitz, A.C., Kopf, R.K., Mesa, M., Phelps, Q., 2011.
