On the Field Study of Shark Behavior

Abstract

The difficulties of observational study of active, wide-ranging sharks in the relatively concealing natural underwater environment are discussed for both baited and non-baited situations. The possible technique of habituating sharks to the diver's presence is considered in view of the logistical and safety problems imposed by the physical limitations of unaided, unprotected human divers. It is concluded that previous sharkobservation methods are inadequate, and that supplementary study techniques must be developed and emphasized. These include remote monitoring by ultrasonic telemetry, telemetry-aided direct observation, and the use of miniature submersibles designed specifically for shark observation.
