Tagging Programs

Scientific researchers have implanted data logging devices, called archival tags, in some tunas, billfish and sharks. Pop-up Satellite Archival Tags (PSAT) are externally attached to the fish and can resemble a torpedo (see photo). Sometimes they are internally implanted, and only the light sensor protrudes out of the body. You can recognize a fish with an internal archival tag by unique external streamer tags that are green and white or orange and white. The white portion of the streamer tag reads “electronic tag inside cavity.” 

If you catch a fish with an archival tag, do not release it. No matter what fishery closures or other regulations are in effect, you may catch, possess, retain, and land an Atlantic highly migratory species in which an archival tag has been implanted or affixed. Please note that this landing allowance applies only to fish with archival tags, not conventional tags.
