Habitat Utilization and Vertical Distribution of the Great Barracuda Sphyraena barracuda (Edwards 1771) in the Western North Atlantic Ocean
The great barracuda, Sphyraena barracuda, is a large predatory teleost commonly seen in the tropics of the Western North Atlantic. There has recently been some stakeholder concern over the population numbers of this species. Using pop-up satellite archival tags (PSATs), six large S. barracuda (85-11...

The great barracuda, Sphyraena barracuda, is a large predatory teleost commonly seen in the tropics of the Western North Atlantic. There has recently been some stakeholder concern over the population numbers of this species. Using pop-up satellite archival tags (PSATs), six large S. barracuda (85-118 cm) were tagged off the coast of South Florida and Bimini, Bahamas. Two of the six tags remained attached to the S. barracuda for the duration of the deployment period. S. barracuda 88094 traveled 471 km MSLD over the 15-day tag duration, while S. barracuda 88095 traveled 1231 km MSLD over its 15-day deployment period.
