[Coral-List] SCTLD on Bonaire

[Brian Walker]

Unfortunately the only approach we have found that works is to treat as many disease lesions as possible through time, but even this is not likely to stop the spread. It will help save corals though.

There is a lot of discussion on the Bonaire forum of ScubaBroad about the presumed futility of restricting divers in order to slow the progressions of SCTLD there. Is there any evidence that this is actually helpful, or is it simply a precautionary approach based on hope?
