2020 Billfish Recaptures Update

The most important data received through TBF’s Tag & Release Program is recapture data. A recapture occurs when a tagged billfish is caught by a second angler subsequent to the tagging and release of a fish. Recapture data contributes toward gaining a better understanding of the species age and growth rates by comparing the reported estimated weight at the time of tagging with the estimated weight upon recapture with consideration given to the amount of time between the two events.  Recapture data also contributes to understanding a species possible site or area fidelity, if tagged and recaptured in the

Their biological characteristics include a spear-like rostrum or “bill,” which is used for slashing at and stunning prey. The dorsal fin of these species runs along a large part of their body and narrow pelvic fins. Billfish can be found spread throughout the worlds oceans and are defined as highly migratory species but typically reside in tropical or sub-tropical waters.  The prey of these apex predators differs from a variety of small fishes to crustaceans and cephalopods (i.e. squid)
