[Coral-List] The Spread of SCTLD

[Rupert Ormond]

Steve,

My understanding is that there is quite good evidence from the Cayman 
Islands that SCTLD is being spread by divers and / or diveboats (in 
ballast tanks?). I believe the main evidence is that they are mainly 
finding SCTLD at dive sites (which are designated with mooring buoys 
etc.) but not or very little on the stretches of reef in between where 
diving is not permitted.

I believe a report on this is due, but at this stage you should probably 
contact the Dept of Environment there for more information, if required.

sincerely,

Rupert

While some locations have taken an approach requiring disinfection of equipment as well limitations on specific dive sites, others have imposed no restrictions at all. From everything I can gather, SCTLD is known to be water-borne and fast spreading and likely bacterial. All of which raises a few questions for the coral disease experts here.
