Large Pelagic Fishes in the Wider Caribbean and Northwest Atlantic Ocean: Movement Patterns Determined from Conventional and Electronic Tagging
Conventional tagging data has documented long distance movements (including trans-Atlantic movements) in blue marlin (Makaira nigricans) and yellowfin tuna (Thunnus albacares) within the Atlantic. Swordfish (Xiphius gladius) have also been shown to move substantial distances, although primarily in a...

Conventional tagging data has documented long distance movements (including trans-Atlantic movements) in blue marlin (Makaira nigricans) and yellowfin tuna (Thunnus albacares) within the Atlantic. Swordfish (Xiphius gladius) have also been shown to move substantial distances, although primarily in a north-south direction. There is, however, a paucity of data for wahoo (Acanthocybium solandri). In the past several years, electronic archival (i.e., data recording) tags have significantly advanced our understanding of the behavior and movement patterns of large pelagic fishes. Data from electronic arcltival tags have generally corroborated conventional tagging data with respect to long distance movements, as well as the daily vertical movement patterns previously obtained through acoustic telemetry.
