Manta Rays receive international protection from the Convention on Migratory Species of Wild Animals

December 1, 2011 § Leave a comment

WildAid applauds the recent listing of the giant manta ray (Manta birostris) under Appendix I and II in the Convention on Migratory Species of Wild Animals (CMS), an international treaty organization concerned with conserving migratory species and habitats on a global scale. Listed on November 25, 2011, member countries are now obligated to provide strict national protections for giant manta rays and their key habitats.

Despite being protected in several countries, manta rays migrate into unprotected waters where they are subject to overfishing. CMS listing will spark coordinated conservation efforts among member countries to monitor the species and protect its habitat.

According to the International Union for Conservation of Nature (IUCN), which declared giant manta rays as Vulnerable with an elevated risk of extinction earlier this month, intense fishing pressures and growing international consumer demand have caused manta ray populations to decline by 30% worldwide, with some regions experiencing an 80% decline over the last 75 years.

Manta rays and their close cousin, mobula rays, are highly valued in Chinese traditional medicine for their gill rakers, cartilaginous projections along the gill arches used for trapping food particles when filter-feeding. Previously targeted by small-scale subsistence fisheries, increasing consumer demand has expanded the gill raker trade into a global commercial industry. According to the IUCN, targeted manta ray fisheries now operate in critical habitats and well-known aggregation sites in the Philippines, Mexico, Mozambique, Madagascar, India, Sri Lanka, Brazil, Tanzania and Indonesia.

The Manta Ray of Hope project, a joint effort of WildAid and Shark Savers, assisted Ecuador’s CMS delegates in shaping the proposal to list manta rays as well as made available to all CMS delegates a condensed version of its forthcoming Manta Ray of Hope report prior to the 10th CMS meeting in Bergen, Norway earlier this month.

The report, which will be released to the public in December, provides the most far-reaching documentation ever conducted on the intensive overfishing of mantas and mobulas and the growing pressures that have pushed these animals to the brink of local extinctions.

“CMS listing is a critical step needed to end the exploitation of mantas and mobulas”, said Peter Knights, Executive Director of WildAid. “By harnessing the cooperation and concerted efforts of member states, the CMS listing sets the stage for cohesive monitoring and regulation of the gill raker trade”.

For its submission to CMS, the Manta Ray of Hope team, led by Shawn Heinrichs, worked with partners in Ecuador, the country that sponsored the move to protect mantas, including local NGO Equilibrio Azul. The team also consulted with Dr. Andrea Marshall, Guy Stevens and Sonja Fordham of Shark Advocates International in advance of the CMS meeting to assist with preparations.

About Manta Ray of Hope: WildAid, Shark Savers, and a team of the top manta researchers in the world are partners in the Manta Ray of Hope project, a collaboration of non-profit organizations, researchers, dive operators, governments and local communities to save mantas and mobulas from this unsustainable trade. Manta Ray of Hope is developing global conservation campaigns based on sound science, including:

  • An upcoming report on the destructive fishing and consumption of Mobulids.
  • Establishment of trade bans and sanctuaries.
  • Education and awareness campaigns for consumers.
  • Ecotourism development in fishing communities.

Manta Ray of Hope receives support from the Silvercrest Foundation, Hrothgar Investments Ltd, and private donors.

Manta Ray Migration Study

Real-time tracking of multiple rays is possible thanks to joint efforts of the Galapagos National Park, National Park Foundation Machalilla Equilibrio Azul.

Last week, two technicians from the Galapagos National Park,  three officials Machalilla National Park, and two divers from Equilibrio Azul, established the monitoring and marking of rays in the island of La Plata on the coast of Manabi, in order to obtain information on the movements of rays.

During the trip, which lasted four days, placed tranmitters on six manta rays.  These tramsmitters emit signals to a receiver installed in different parts of the coast.

Tags were also placed on three rays which emit signals in real time to the satellite monitoring center installed in the offices of the Galapagos National Park Service on the island of Santa Cruz

The first satellite images show that the rays are moving around the island off the coast of Manta and Bahia de Caraquez. 

“The goal of this project is to measure the migration patterns of this species in the coastal area to see if there are other sites that are preferred for them on the Ecuadorian coast and can be protected, in addition to verifying whether there is connectivity with other areas like the Galapagos or the South Pacific region, “said the ranger Eduardo Espinoza, head of the Galapagos National Park Marine Research. 

Manta rays are a protected species by the Ecuadorian government since 2010, including in the list of endangered species by the International Union for Conservation of Nature (IUCN), but most are considered a symbol of tourism in some dive sites Ecuadorian coast.

January through March  is considered manta ray season where  Galapagos divers can dive with rays off the coast of Isabela.
