Habitat Utilization and Vertical Movements of White Marlin (Tetrapturus albidus) Released from Commercial and Recreational Fishing Gears in the Western North Atlantic Ocean: Inferences from Short Duration Pop-up Archival Satellite Tags
behavioral and oceanographic parameters to standardize historical catch-per-unit-effort time-series data. These methods have allowed researchers to account for significant changes in the depths of pelagic longline (PLL) gear deployments over time. This study presents habitat-use data recovered from...

These methods have allowed researchers to account for significant changes in the depths of pelagic longline (PLL) gear deployments over time. This study presents habitat-use data recovered from high-resolution 5- and 10-day pop-up satellite archival tags (PSATs) attached to 47 surviving white marlin released from commercial and recreational fishing gears offshore of the U.S. East Coast, the northern Caribbean, and Venezuela between 2002 and 2004. Data recovered from transmitting tags indicated that white marlin spent nearly half of their time associated with warm, near-surface waters (<10 m). All fish displayed frequent short duration (mean: 39.8 min) vertical excursions from surface waters to depths averaging 51 m. Qualitative and multivariate classifications of data from completely transmitted movements of surviving white marlin revealed two major types of descents: one pattern was characterized by deep ‘V’-shaped excursions of relatively short duration (mean: 23.4 min) while the other featured descents that were more broadly ‘U’-shaped and confined to a specific depth range for an extended period of time (mean: 75.8 min). Based on the frequency, persistence, and patterns of these vertical movements, white marlin appear to direct a considerable proportion of foraging effort well below surface waters, a behavior that may account for relatively high catch rates of white marlin on some deep-set PLL deployments.
