Scientists are concerned about unregulated feeding of ocean wildlife by tour operators. It took nearly three months, but Jody Pinder eventually succeeded. Endangered green sea turtles, usually shy, skittish and satisfied with a diet of sea grass and algae, were accepting handouts of squid that he and other local tour operators were providing at Bottom Harbor in the Bahamas. “If you don’t feed them, they won’t come close enough for you to see them and photograph them,” Mr. Pinder said. Before the pandemic, Mr. Pinder and others had been selling this assured adventure to a booming population of tourists. Day after day, boats would flock to Bottom Harbor and tourists would hop into its shallow turquoise waters holding squid morsels in their hands or on wooden skewers. The turtles would then grab the snacks as the visitors snapped Instagram-worthy images. Those who don’t take care sometimes find themselves getting bitten by the aquatic animals, who may mistake human toes and fingers for another snack. The practice is known as provisioning, and it’s an easy meal for the shelled creatures. But conservation biologists have expressed concern in a number of recent published scientific studies about what this food source means for the physical well-being and natural behavior of not just these turtles, but other marine creatures, from tiny reef fish to giant sharks. “This situation exemplifies one of the biggest challenges in conservation science,” said Owen O’Shea, executive director of the Center for Ocean Research and Education in the Bahamas. “We’re often addressing issues that have already started and we’re playing catch up.” Many experts argue that in marine environments, such feeding practices are poorly regulated, presenting risks for wildlife that are already in decline. When humans ease the energy-intensive process of seeking food for wild animals by frequently offering them grub, it can facilitate habituation. That can... |
