Climate change, stress keeping butanding away, say local officials
Rising sea temperature due to climate change, stress and lack of food are keeping the whale shark, locally know as butanding, far from the coastal waters of this town and causing them to linger in other areas where plankton is abundant, a butanding interaction officer (BIO) said.
Alan Amanse, chair of the BIO Board of Donsol, said sightings of butanding in waters here have dropped from eight last year to only two in the first half of this year, endangering the tourism industry of the town.
Amanse said sea temperature has significantly increased from 26-27 degree Celsius last year to 29-30 degree Celsius this year.
There are currently only two whale sharks swimming off Donsol waters. They are “Curly,” which has a curly dorsal fin, and “Lucky,” which has a nylon cord tied to its tail.
“The bigger ones measuring 14 meters long are nowhere in sight,” said Amanse.
He said gone are the likes of the famous “Putol,” which has no caudal or tail fin, and “Nognog,” thus named for its dark color.
Amanse said the butanding are also suffering from stress because of the many interaction events conducted by the BIO during the butanding season from December to May.
He said there are at least 40 boats with six tourists each on board interacting with whale sharks in every event.
Town councilor Rey Aquino said the rampant harvesting of plankton by fishermen and the presence of E. coli contamination in the Donsol River due to the presence of household toilets along riverbanks further contributed to the scarcity of food in the feeding grounds of the butanding.
Amanse said the tourism industry of the town is hurting, losing millions of pesos in revenue.
He said tourist arrivals dropped by 2,000 during the first half of this year, or close to 10 percent, from an average of 25,000 since 2007, Amanse said.
Amabel de la Cruz, Donsol Tourism Council revenue collector, in an interview, said the town’s tourist arrivals translated into some P4 million in revenues in 2012.
She said revenue collection for the past six months of this year reached only P2 million. De la Cruz, however, said she hoped revenues this year will match last year’s.
Another environment issue confronting Donsol is the cutting of mangrove trees in Barangay Ogod by residents who use these as a parking area for boats.
Aside from being tagged as the butanding capital of the country, Donsol has other tourist attractions like the “Firefly Watch” in Ogod River and an 800-square-kilometer fish sanctuary near the coastal villages of Sibago, Tinanogan and San Rafael.
Donsol town is a third class town in Sorsogon with a population of more than 47,000.
