BRUV stands for Baited Remote Underwater Video and part of Dr. Mark Bond’s research to estimate and compare the relative abundance of predator fish species, including sharks and rays, inside and outside marine protected areas (MPAs). These species are also the most commercially valuable and play an important role in the local villages everyday life.
Due to the difficulties of studying elasmobranchs (sharks and rays) abundance in the while, different techniques had to be invested in order to address different ecological questions. One of these techniques is the Baited Remote Underwater Video (BRUV). This shark study method has been used in numerous studies around the world and has been show very successful.
A metal structure with 1 kilo of smashed bait is weighted and brought down to the ocean floor where it is left for 1.5 hours to record. After it has been retrieved the data is transferred and analysed by the IOP Volunteers at project headquarters in the afternoon data sessions. This data is submitted onto an online forum and shared with Dr. Bond.
