New research from Ascension Island shows that shark conservation cannot depend on biology alone. Community experience, fear, fishing losses and trust in evidence all shape whether people support protection measures for threatened marine predators.
Ascension Island is a UK territory in the South Atlantic with a small resident population. After two non-fatal shark attacks in 2017, local concern increased around interactions with sharks, especially among recreational fishers who reported losing hooked fish and gear before catches could be landed. Silky sharks and Galapagos sharks were among the species frequently discussed in the study.
What the Researchers Studied
A team led by researchers from the University of Exeter and ZSL interviewed 34 island residents to understand how people perceived shark behaviour, shark numbers and possible management options. The study was published in People and Nature under the title Social dimensions of shark-human interactions in a large remote Marine Protected Area.
The findings show that shark-human conflict is shaped by more than direct attacks. Uncertainty over which species are involved, why interactions are increasing and whether past human activities such as chumming influenced shark behaviour all contributed to anxiety in the community.
Marine Protected Area Context
Ascension Island became a Marine Protected Area in 2019. Recreational fishing is allowed in nearshore waters from the coast to 12 nautical miles, while fishing is prohibited from 12 to 200 nautical miles. Reports of shark-human interactions have risen over the last decade, and the study found that many residents had reduced their ocean use because of concern about sharks.
Why the Study Matters for Fisheries and Conservation
For fisheries managers and conservation planners, the lesson is practical: protection measures need strong community trust. Evidence-based information, local participation in monitoring and clearer communication about shark movements can reduce uncertainty and help prevent conflict from undermining conservation support.
The research is also part of a wider effort to track sharks around Ascension Island and understand how ocean conditions influence their movements and interactions with people. That kind of combined social and ecological approach is important for remote marine protected areas where fishing, safety and biodiversity goals overlap.
