Environment Planet Earth Researchers Wrangle Sharks in the Bahamas to Improve Marine Preserves By David DeFranza Updated February 22, 2021 One World One Ocean Share Twitter Pinterest Email Planet Earth Conservation Weather Outdoors Last year, Kristofor Lofgren—a restauranteur who owns a sustainable sushi restaurant—proposed an interesting idea. At the 2011 Summit at Sea in the Bahamas, he presented the idea of using revenue from his restaurant to help create marine protected areas where fish could find sanctuary and reproduce. The conservationists in attendance liked the idea but identified a few problems that had to be addressed before it could be implemented. credit: One World One Ocean The Caribbean region has been identified by the IUCN as one of the world's "biodiversity hotspots"—meaning that it holds a high concentration of plants, animals, and fungi spread across a large number of ecosystems. Part of this, of course, are the region's marine resources. The Caribbean is home to eight percent of the world's coral reefs. credit: One World One Ocean These reef ecosystems, however, are under increasing threat. In addition to climate change, ocean acidification, overfishing, and pollution, invasive species like the lion fish have begun ravaging native populations.

But conservationists cannot simply rope off large swaths of ocean and expect damaged ecosystems to recover on their own. Indeed, planning an effective marine preserve requires careful consideration of the many—and sometimes divergent—needs of plant, animal, and human communities. This is why—motivated by Lofgren's proposal—a team of researchers traveled to the Caribbean to gain a better understanding of one large group of apex predators: sharks.

To accomplish the task a researcher must delicately clamp the transmitter to one of the shark's fins.

Still, research and conservation in one area can have a ripple effect—sending beneficial waves out across the entire Caribbean.
