![]() ![]() Peru is home to the world's largest known population of giant manta rays. Manta rays reproduce extremely slowly, giving birth to one pup every two to five years, so even limited fishing has a significant impact. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Little is known about overall numbers, but the International Union for Conservation of Nature’s Red List, which provides data on the population and conservation status of species, has found that certain regional populations have dropped by 80 percent during the past 75 years. Demand has soared in recent years, in part as an alternative to shark fin.Ī recent New York Times report noted that overfishing has wrought havoc on many of the world’s manta populations. ![]() There’s no scientific evidence that manta potions are effective in any of these instances.Īccording to WildAid, an NGO that aims to stop illegal trade in wildlife, the manta gill plate trade amounts to $30 million a year, 99 percent of it accounted for by one Chinese province: Guangzhou. The gill plates are considered a culinary delicacy in China, where they’re also used in traditional medicine to reduce toxins, enhance blood circulation, cure cancer, increase breast milk supply, and treat chickenpox and other ailments. But rays are also deliberately targeted for their meat and gills plates, which filter out plankton as they swim. It’s not unusual for manta rays to get tangled in nets or fishing lines. On December 31, 2015, Peru took a major step toward helping giant manta rays when it passed a resolution that not only bans manta fishing but also requires that fishermen immediately release any mantas caught accidentally as “bycatch” back into the ocean. The accidental snagging of this large ray (giant oceanic manta rays can weigh up to two tons) served to highlight global threats the rays face, and it spotlighted Peru, in whose waters many of the giants are found. Giant manta rays captured the world’s attention last April when a fisherman in northern Peru unintentionally caught a behemoth weighing 2,000 pounds (900 kilograms).
