  abstract = {{D}olphinfish ({C}oryphaena hippurus), large pelagic predators and important fishery targets, frequently associate with floating debris or manmade fish aggregating devices ({FAD}s). {W}e tagged 8 dolphinfish with pressure-sensitive ultrasonic transmitters and actively tracked individuals continuously for up to 40 h to elucidate the vertical movement patterns and differences between {FAD}associated ({FAD}-{A}) and {FAD}-unassociated ({FAD}-{U}) fish. {F}our additional fish were equipped with acoustic transmitters and passively monitored for several days with receivers attached to {FAD}s. {W}hen not associated with {FAD}s, dolphinfish used the upper 75-100 m of the water column during the day and made descents up to 160 m during the night. {I}n contrast, {FAD}-{A} fish generally stayed within the upper 10 m of the water column and tended to make deeper excursions during the day rather than at night. {W}ater temperature data from expendable bathythermo-graphs deployed during active tracking showed that fish only descended to depths where temperatures were <= 3 degrees {C} cooler than the uniform-temperature surface layer. {T}he use of vertical behavior to determine whether a dolphinfish is associated or not with a floating object opens the possibility for new, large-scale research aimed at investigating the role of floating objects in the ecosystem inhabited by this species and at assessing the impacts of {FAD}s on its ecology.},
