New coral growing technique from Bunaken:
Pahlano Daud, a reef expert from Manado, North Sulawesi, spent the weekend with us at Les Village.
Pahlano compared notes with the fisherfolks of the village on the reef rebuilding they are doing at Bunaken National Maritime Park in North Sulawesi. Over tua (palm wine) and bakso, they talked about a broader community formation that cares about the sea, similar to one in Bunaken, people to people sharing program, and the various shapes and structures experimented on in Les and Bunaken for hosting coral tranplants.
He introduced in Les the line method used in Bunaken. Working with Pak Eka, they tied a string that ran from end to end of the Adopt-A-Coral structure and then tied coral transplants in the entire length of the line. In Bunaken, such lines serve well as nursery, allowing the newly cut coral colony to stabilize and grow before it's transplanted to a final site -- could be other artificial structures or empty spaces in the sea floor that could host corals, or places where natural corals have died due to bleaching,etc.. The line method is cheap and a great way to provide a halfway home to broken corals lying on the sea floor due to action of the current, carelessness of people, etc.
Pahlano also had a look at the 4-year old METRO table-type artificial reef. In addition to the corals that were transplanted years ago, Pahlano has identified at least 20 coral species that have attached themselves naturally on the concrete blocks. They're the blots on the surface of the blocks -- white, yellow, pink, blue -- that looked like melted candle wax. They're nascent coral colonies. He said the area is ripe for a scientific research study on corals,marine ecology, etc.
