Managing shark-human interactions is a key social and environmental challenge that needs resolving if we are to maintain shark populations and ecosystem function. Shallow coastal marine environments are known to provide nursery habitats for many shark and ray species. These shallow nearshore areas are also areas where recreational activities such as swimming and surfing are concentrated. We developed a novel active tracking approach using blimp-mounted cameras to continuously track the presence and movement of sharks, rays and other species. The blimp provides a means for assessing the shallow water space-use and beach visitation rates of large marine animals, providing continuous 8-hour coverage.  A ”spotting” trial was conducted to determine the reliability of this method in different weather conditions and depths. Mobile shark analogues were deployed daily at two depths. Footage was later shown to lifeguards to identify whether the shark analogue was present or absent from the clips shown. During the field trials, the movement behaviour of numerous sharks, rays, fish and seals was also recorded. This technique has relevance to scientists monitoring the movement animals in shallow nearshore environments. The project addresses the key management objective of preventing unwanted shark-human interactions; providing safer beaches whilst conserving marine life.
