Philippines Manta Update - Ticao Manta Conservation
Ticao Island conservation work with manta rays dates back to the early 2000's when a local group called the Blue Zoo worked with Save-the-Mantas.org to develop posters that were displayed in the ports and fish markets to persuade fisherman to not kill the rays. The poster were very effective and led directly to today’s protection of manta rays and whale sharks in many of the areas of the Philippines.
In 2002, Rico Calleja, a local dive instructor, heard stories from local fishermen about a large number of mantas in an area off Ticao island. This information helped him pinpoint the location of a manta cleaning station. After operating a dive shop in Donsol he later established a conservation station that would become Ticao Island Resort.
Marvin Mondrano, Abel Bahillo and others recorded frequent manta sightings at the cleaning station which was named the Manta Bowl. This area has become a very popular dive destination.
The resident manta population has been studied with 30-40 individuals identified. The Manta Bowl cleaning station is an ideal location to record sightings over a long period of time and is useful in distinguishing the resident population from the pelagic (migratory) animals.
More recent research by Yotam Barr, a marine biologist from the University of Tel Aviv and ongoing work by LAMAVE (Large Marine Vertebrates NGO) suggests that mantas frequent the area all year for the purpose of getting cleaned by small fish.
Even though the area is protected, manta rays still get caught up in fishing nets. Through the assistance of Mondrano and other local divers, as many as five manta rays are cut free of monofilament fishing lines each year.
