Manta rays are some of the most beautiful and eloquent fish in the ocean, but also one of the most threatened. Harvested for their skin, cartilage, and gill rakers in traditional Chinese medicine, these cartilaginous species are subject to overfishing, bycatch, and a range of other threats.
Today, seven sharks and ray species have gained international protection under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), making it a wonderful day for shark and ray conservation. This means that seven new species have been added to CITES’ Appendix II, which regulates their global trade in an effort to prevent overexploitation.
On September 14, 2014, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) will add seven sharks and rays to Appendix II, meaning that global trade of these species will be restricted. At Oceana, we work to protect marine species from overexploitation every day, so we’re thrilled about the new listings. To celebrate, we’ll be spotlighting all seven species that are receiving protections on September 14 in a series of countdown blog posts on The Beacon.
- Two leading scientists on microplastics have called for urgent action to reduce and eliminate them from the marine environment. The scientists stressed that little is known about these particulates, such as what effect they have on the seafloor and where they’re most commonly found. EurekAlert
We have great news to share with you today! We recently asked you to help us protect manta rays from being made into leather by asking Alibaba.com to take manta ray products off their website. Nearly 40,000 of you responded by signing our petition, and Alibaba listened!
Last Friday, they called us to say that they will no longer be selling manta ray products. Today, we got their statement in writing and are proud to be able to announce their commitment to sustainability. In the past, they’ve taken down listings for shark fins and other unsustainable animal products. And now, thanks to your efforts, they will also refrain from selling animals protected under UN policies, including manta and devil rays.
We are amazed at the response we got from all our wonderful supporters on this topic. We here at Oceana would like to thank all of our supporters for sharing your voices, and we’d especially like to thank Alibaba.com and their CEO Jack Ma for responding so quickly and positively. Thanks to all of you, manta rays are now swimming a little more safely.
Manta rays are one of the most fascinating and unique ocean creatures. As the largest of all the rays, giant manta rays can reach up to 22 feet.
But we have been shocked to discover that Alibaba.com, the world’s largest business-to-business commerce website, with over 65 million registered users, is selling manta ray leather. We are asking you to sign a letter to the president and founder of Alibaba.com to urge this company to stop selling manta ray products.
Today, the world’s manta rays are in trouble, because fisheries are pushing many populations toward collapse. The International Union for Conservation of Nature (IUCN) classifies giant mantas and reef mantas as “vulnerable,” to extinction, and the trends for the majority of manta populations remain unknown.
What’s driving the development of fisheries for manta rays? These animals are prized for several body parts, including their skin, which is made into “leather,” their gill rakers (bony structures inside their gills), which are ground to a powder for traditional Chinese medicine, and their cartilage, which is used as a filler in shark-fin soup. Demand for manta ray parts continues to rise, even though there are available substitutes for manta ray leather, gill rakers have been found to have no medicinal qualities, and cartilage adds no flavor to shark-fin soup.
Only once these products are taken off the market and the overall demand from manta ray parts is reduced do these vulnerable animals have a shot at recovery.
In spite of their formidable size, these ocean giants are not to be feared: they are gentle plankton-feeders that spend their time gliding peacefully through the open ocean of the tropics. There are two species of manta rays, and the chance to see an individual in the wild draws scores of tourists each year to manta ray “hotspots” in locales such as Hawaii, Micronesia, and Mozambique.
Like their shark relatives, manta rays are long-lived and mature slowly. They give birth to live pups every two to three years. These characteristics make manta rays extremely susceptible to overfishing, because populations can be fished out faster than they can be replaced. And once a manta ray population is depleted, it may take decades for full recovery to occur.
