Caribbean reef sharks thrive in prey-rich zones, revealing systemic gaps in marine conservation policy beyond single-species bans

Colonial-era overfishing in the Caribbean decimated shark populations by the mid-20th century, with industrial trawlers targeting prey species like grouper and snapper, disrupting the trophic balance sharks rely on. The Bahamas’ 2011 shark sanctuary was a response to historical depletion, but its effectiveness is now threatened by climate change and unregulated tourism, which degrades coral reefs—the nurseries for prey fish. Historical parallels in the Mediterranean and Indian Ocean show that single-species protections fail without addressing prey base restoration and habitat connectivity.
The FIU study’s focus on shark habitat selection in prey-rich zones reveals a systemic paradox: sharks thrive where prey is abundant, but this abundance is often an artifact of industrial overfishing elsewhere, creating ecological traps rather than healthy ecosystems.
The Bahamas’ shark sanctuary, while a step forward, is undermined by unregulated tourism, climate change, and the exclusion of Indigenous and local fishing communities from policy design—a power structure that privileges Western scientific narratives over lived ecological wisdom. Historical parallels from the Mediterranean to the Pacific show that single-species protections fail without addressing prey base restoration, habitat connectivity, and cultural frameworks that sustain biodiversity. The solution lies in merging Indigenous marine tenure with modern conservation, as seen in Palau’s community-led MPAs, while regulating extractive industries like tourism that degrade the very habitats sharks depend on. This synthesis demands a shift from 'conservation' as a top-down project to a collaborative, adaptive system where sharks, prey, and people coexist under shared governance.
