BRUVS reveal locally extinct shark and the way for shark monitoring in Brazilian oceanic islands

J Fish Biol. 2020 Feb;96(2):539-542. doi: 10.1111/jfb.14228. Epub 2019 Dec 20.

Abstract

Here we present records of sharks obtained using baited remote underwater stereo-video systems (stereo-BRUVS) at two Brazilian oceanic islands. Fourteen of the 60 deployments recorded 19 sharks in Trindade Island. In Saint Peter and Saint Paul Archipelago (SPSPA), two pelagic and two demersal deployments recorded two and one shark, respectively, including the locally extinct Galapagos shark Carcharhinus galapagensis. Stereo-BRUVS should be considered as adjuncts to other non-invasive methods to monitor shark populations.

Keywords: Carcharhinus galapagensis; conservation status; elasmobranch; reef fish; south-western Atlantic Ocean.
