Global census reveals reef shark status, need for improved conservation management

Summary

A global census, with KAUST participation, assessed reef shark populations using Baited Remote Underwater Video Systems (BRUVS). The study found reef shark populations thrive where there are marine conservation policies and fishing regulations. However, they are scarce in areas with overfishing and poor resource protections, with sharks absent on nearly 20% of surveyed reefs. Why it matters: The research highlights the importance of conservation management for reef sharks, key apex predators and indicators of reef health, especially in the Red Sea region.
