We tagged 12 Carcharhinus limbatus with acoustic transmitters and monitored their presence at five piers along the north‐east coast of South Carolina, USA in 2016 and four piers in 2017 using acoustic receivers. Data were analysed with pier association indices (PAI), mixed models and fast Fourier transformation analyses to identify potential factors ...

Fish physiology is significantly affected by temperature variability. During fisheries interactions, fish are often exposed to air and subjected to rapid temperature changes. Fish thermal dynamics during such exposure, and the possible outcomes to their physiology, depend on how heat is distributed across their bodies, the speed at which their body ...

AbstractNew approaches to abundance surveying utilizing unoccupied aerial vehicles (UAVs) are proving to be effective tools in marine and terrestrial environments. We explored UAV efficacy for surveys in the Galapagos Marine Reserve (GMR), where relative abundance patterns of juvenile sharks and subsequent classifications of putative nursery areas ...

I analyzed and quantified the behavior of blacktip sharks, Carcharhinus limbatus, irritated by sharksuckers, Echeneis naucrates, attached to their bodies. The sharksucker induced behavior patterns were divided into simple rotational patterns, expressed by body turns along their main axes (roll, yaw, pitch); and complex patterns (wiggle, shake, wind ...

Although chafing-the rubbing of a body on the sea floor-is a common response of sharks to the attachment of irritating sharksuckers (Echeneis spp.), this behavior has not yet been analyzed in detail. I focused on the different forms and functions of chafing, with special emphasis on the use of sand ripples by sharks during chafing. A significant number
