Tagged fish

Fishing Wisconsin

The Department of Natural Resources (DNR) fisheries biologists track fish for research purposes. There are various ways DNR marks fish which are part of these research studies:

  • a tag is attached to the fish, or
  • a radio transmitter is implanted, as noted by a wire antenna, or
  • a code wire tag is implanted, as identified by a missing adipose fin.

It is illegal to tag fish unless given a permit by the DNR.

Should you catch a DNR-tagged fish, it is very important to report the requested information promptly. The information provided by the angler helps DNR to determine fish population estimates, and harvest and exploitation rates. Your cooperation and participation are greatly appreciated.

If you release the fish, please do not remove the tags.

The tag

tagged walleye
The walleye long tag is attached to the fin

 

One common type of tag looks like a 2-inch piece of spaghetti and is located near the base of the dorsal fin (i.e., the fin along the top of the back). The tag can be of several colors. For example, on the Winnebago system, it will either be orange or yellow. Look carefully, as the tag may be covered with algae and look like a piece of a weed. Another type is a metal tag found on the dorsal fin of the fish. Each tag has a unique serial number stamped on it that identifies that fish. It may also have an address to send the tag to.

Requested information

Should you catch a tagged fish, it is very important to report it promptly. The information that DNR fish biologists request is fairly simple:

  • The species of fish caught.
  • The date the fish was caught.
  • The specific location where it was caught.
  • Whether it was kept or not.
  • Most importantly, the tag (i.e., serial) number.

You may also include the fish's length and weight if you know it.

If you release the fish:

  • Do not remove the tag.
  • Record the information requested above and send it in promptly to DNR or other agencies listed below.

If you keep the fish:

  • Remove the tag.
  • Don't scrape off any algae, because you may also remove the lettering on the tag.
  • Tape the tag to a card and send it in promptly to the DNR.

Sending in your information

If the tag has an address on it, send the information to that address. If your fish was caught in the following waters, follow the link to find the name and address below where you may send your information.
