The Northeast Fisheries Science Center’s Apex Predators Program studies the life history and ecology of sharks in the marine and coastal waters of New England and the Mid-Atlantic. In 1962, they began the Cooperative Shark Tagging Program with about 100 volunteer recreational and commercial fishermen, scientists, and fisheries observers. Today they have more than 7000 volunteers contributing data to the Tagging Program.
More than 295,000 sharks, comprising more than 50 species, have been tagged to date. The data from tagging and recapture events have been instrumental in shaping what we know about shark migration and distribution. It also helped to define the essential fish habitat for 38 federally managed shark species. It continues to be used for defining and updating areas designated as essential for shark survival.
Blue sharks (Prionace glauca) are a common pelagic species found in New England waters. More than 122,000 blue sharks have been tagged to date and they’re the most tagged species of shark in our Tagging Program’s database. In fact, they account for 42% of all the tagged sharks recorded in our database and of the more than 122,000 tagged blue sharks, 7% of them have been recaptured at least once.
