How to Report an NMFS Shark Tag

Initiated by the National Marine Fisheries Service (NMFS) in 1962, the Cooperative Shark Tagging Program studies the biology of Atlantic Ocean sharks by physically tagging them with fin, dart or Hallprint identification markers. If you catch a tagged shark, the NMFS offers an incentive for returning the tag to its Apex Predators Program facility in Narragansett, Rhode Island.
