The Large Pelagics Research Center (LPRC), based in Gloucester, Mass., initiated its Tag A Tiny program in 2006 to study the annual migration paths and habitat use of juvenile Atlantic bluefin tuna. Through this co-operative tagging program, which uses tags from The Billfish Foundation (Ft. Lauderdale, Fla.) recreational anglers and charter captains catch, measure and release juvenile bluefin with conventional "spaghetti"-ID tags.

To date, 885 recreational fishermen have helped LPRC to tag 1,006 bluefin, mostly juveniles from one to four years old, and some "medium" size fish, nearing 180 centimeters. All of the records are entered into the Billfish Foundation, National Marine Fisheries Service (NMFS), and The International Commission for the Conservation of Atlantic Tunas (ICCAT) databases.

LPRC was established in 2003 at the University of New Hampshire and, in 2010, joined the Department of Environmental Conservation at the University of Massachusetts-Amherst and the Graduate School of Marine Science.
