19-11-2012 | Coral Rehabilitation Initiative - successful fieldtrip Australia

From 1 until 15 November 2012, MichaŽl Laterveer of Blue Linked stayed in Australia to witness the coral spawning at the Great Barrier Reef. The working visit was part of the Coral Rehabilitation Initiative.

The culturing systems that were developed by Blue Linked for the Coral Rehabilitation Initiative operate very well. In cooperation with the Australian Institute of Marine Science (Townsville) and the University of New South Wales (Sydney), MichaŽl Laterveer succeeded in growing tenthousands of coral embryo's into healthy coral larvae.

Well after two days (52 hrs) following fertilization, the coral embryo's have developed into elongated larvae that start swimming. Then, the larvae start searching their surroundings for a place to settle. After settlement the larvae will develop into a primary polyp: the start of a new coral colony.

Blue Linked has developed special tiles for the settlement of coral larvae. The tiles are designed and manufactured by the Dutch company K&S Decor. MichaŽl Laterveer could not await the larvae settlement in Australia. Therefore, this process is carried out by collaborating Australian scientists.
