Cooperative Tagging Center (CTC)

Our volunteer tagging program emphasizes highly migratory species (tunas and billfishes).  Since 1954, over 200,000 billfish and tunas have been tagged with our conventional streamer tags, providing valuable information about movement patterns, as well as documenting the rapid rise and resounding success of our catch and release outreach efforts. The CTC works in collaboration with The Billfish Foundation to enhance billfish tagging efforts throughout the Atlantic Ocean and beyond.
