“…With the bigeye thresher (from our own study and others) consistently occupying comparatively shallower waters at night, and the scalloped hammerhead in similar depth ranges, both of these species are at risk of overlapping with nighttime operating tuna and swordfish commercial fisheries in the GOM [35,52,53]. In addition, there is a growing recreational and commercial industry of daytime deepdrop swordfish fisheries [54] that can heavily interact with bigeye threshers as they remain in deeper waters during the day. These fisheries routinely alter gear characteristics, location, fishing depth, and time of day of deployment to maximize catch rates of their target species; however, these adjustments can then alter the composition (e.g., species, sex, maturity) and magnitude of bycatch [52,53].…”
