I can never get the quote function to work , but hopefully SCTLD hasn’t actually made it to Asia (so presumably that is why you saw very little of it). As I recall it started off Miami Beach then progressed outward along the coast (north /south ) 20-30 miles a year before “mysteriously” hopping to various cruise ship ports in the Caribbean . I assume you are talking about Coral bleaching which unfortunately occurs worldwide (you said you were a relatively new diver , so this would be an easy mistake to make ).
If by chance SCTLD (Stony Coral Tissue Loss Disease ) has made it to Asia that is something I would be interested to know (but I really , really hope it hasn’t happened )
Point taken. At Puerta Galera, I saw (and noted) the following:
Rare fields of coral rubble- From less than 50 square meters to over a hundred square meters. These could have been the result of storm damage, predation, or disease. These rubble fields consisted of old, algae encrusted, small broken pieces of generally one particular coral and were location-specific with some having none:
Some bleaching- Mostly tips and fringes of finger corals, table corals and a few porites:
Soft corals weren't entirely immune to bleaching either, especially in shallower warm waters:
Occasional dead corals- A few dead, large table corals and some dead mounding corals. Usually covered with some stage of algal growth.
(oops...only 5 attachments allowed)
Rare "white band disease"- I saw it just a few handful of times on some mounding corals, but made note because I saw it rampant on Roatan's shallower reefs. This one seen at Verde Island:
As far as I know, this white band disease is fast, lethal, and highly contagious (at least to Caribbean coral) and distinct from bleaching.
I don't know anything about the local history of coral diseases, so I can't really say anything about what I saw beyond noting the occurrences of bleaching and SCLTD.
If anyone can comment on these images, I'd certainly appreciate it.
