Whale Shark Tourism Harms Coral Reefs

Scientists in Hong Kong, the Philippines and Guam have found that whale shark tourism in Tan-awan, Oslob, the Philippines, has led to degradation of the local coral reef ecosystem. They reported their findings in Environmental Management. From a report: Oslob, a small municipality on the south coast of Cebu, the Philippines, has become a domestic and international tourism hotspot since 2011, attracting over 300,000 visitors to the village of Tan-awan in 2015. The mass tourism phenomenon is fueled by the year-round presence of whale sharks along the local shallow reef. This unusual aggregation is maintained by the local tourism association feeding the whale sharks with up to 50 tons of shrimps annually. In this study, scientists from the University of Hong Kong (HKU), the University of Guam, and the Large Marine Vertebrates Research Institute Philippines (LAMAVE) have demonstrated that whale shark tourism has had a detrimental effect on the local reef ecosystem off the coast of Tan-awan. They found that Tan-awan had higher macroalgae and lower coral density, as well as a less diverse coral community dominated by weedy corals and stress-tolerant corals, in comparison to a reference site further south of the coast. [...] The researchers added that reef degradation in Tan-awan requires immediate attention, given that reef health underpins the ecosystem services afforded to the local communities, including the important tourism sector. As whale shark tourism is projected to grow continuously in the foreseeable future, the research team urges the need for local authorities to implement proper management strategies to mitigate the problems and risks associated with the rapid tourism development.
