Tag and release is a form of catch and release fishing in which the angler attaches a tag to the fish, records data such as date, time, place, and type of fish on a standardized postcard, and submits this card to a fisheries agency or conservation organization. Anglers who catch tagged fish report their location, date, and time, as well as the tag number to established points of contact. South Carolina has had such a program since 1974.

A tag and release program is in place in NSW, Australia.
