The welfare impacts of manta ray marine tourism and how responsible wildlife watching protects these gentle giants.
Manta ray tourism provides powerful conservation incentives that have been instrumental in changing fishing practices in many countries. However, tourism itself creates welfare concerns when interactions are poorly managed. Touching manta rays removes the mucus coating that protects against infection. Diver crowding at cleaning stations disrupts the parasite removal behavior that motivates aggregation. Flash photography causes stress responses. Boat strikes and propeller injuries are significant causes of manta ray mortality near popular tourism sites. Well-designed tourism codes of conduct that prohibit touching, limit diver numbers, and require boat speed restrictions near known aggregations protect individual welfare while maintaining the economic benefits that support conservation.
