Recently published in Frontiers in Marine Science, a new study by Dércio Maoze, Jule Buschmann, Acácio Chechene, Dave van Beuningen and Dr. Mario Lebratohighlights the importance of Mozambique’s coastline for threatened sharks and rays in the Western Indian Ocean.
Using two decades of citizen science observations, the research reveals important biodiversity patterns, conservation priorities, and protection gaps for species such as whale sharks, giant manta rays, bull sharks, scalloped hammerheads, round ribbontail rays, and bluespotted ribbontail rays.
Key findings include:
• 408 observations analysed
• 44 species reliably identified
• 71% of recorded species were threatened
• Over 90% of records overlapped with Important Shark and Ray Areas (ISRAs)
• Only 17% overlapped with Marine Protected Areas (MPAs)
The study shows how citizen science can support evidence-based conservation, marine planning, and long-term protection of Mozambique’s globally significant marine ecosystems.
