Abstract
Short-duration (5- or 10-day) deployments of pop-up satellite archival tags were used to estimate survival of white marlin (Tetrapturus albidus) released from the western North Atlantic recreational fishery. Forty-one tags, each recording temperature, pressure, and light level readings approximately every two minutes for 5-day tags (n=5) or four minutes for 10-day tags (n=36), were attached to white marlin caught with dead baits rigged on straight-shank ("J") hooks (n=21) or circle hooks (n = 20) in offshore waters of the U.S. Mid-Atlantic region, the Dominican Republic, Mexico, and Venezuela. Forty tags (97.8%) transmitted data to the satellites of the Argos system, and 33 tags (82.5%) transmitted data consistent with survival of tagged animals over the deployment duration. Approximately 61% (range: 19-95%) of all archived data were successfully recovered from each tag. Survival was significantly (P
