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.
