SCTLD: Be part of the solution

SCTLD: Be part of the solution

We’re not the only ones on Earth trying to combat devastating diseases these days. The MesoAmerican Reef in the Caribbean has been facing its own pandemic caused by new disease called Stony Coral Tissue Loss disease.

Divers will ask us from time to time about the difference they are seeing in the coral. Many are sad to hear about the havoc this disease is wreaking on the reef system of their beloved Roatan and want to do something to help. Luckily, there is hope and divers can be a part of the solution.

So what exactly is Stony Coral Tissue Loss Disease?

The truth is that the scientific community is still working to understand exactly what SCTLD is. But, there is strong reason to believe that the disease is bacterial, based upon the efficacy of antibiotic treatments (more on these in a minute!).

It effects over 24 types of stony corals. Iconic pillar corals, big and beautiful boulder brain corals and star and starlet corals being the most susceptible. The disease is characterized by freshly exposed white skeleton that usually forms in circular lesions, first appearing along the borders of coral colonies.

Do we know where it came from?

The disease first came on the radar in 2014 in Florida. That year there was a trifecta of incidences that wreaked havoc on the reef system there:

  1. 2014 was (and still is) the hottest year on record
  2. Coral colonies were getting hit hard with bleaching and
  3. the dredging of the Miami Port was badly damaging the reef. This trifecta made coral colonies weaker, less able to fight against diseases like SCTLD.

From Florida, the disease quickly spread across the Caribbean, ultimately making its way to Roatan in September of 2020.

Is there a cure?

There is still not a surefire way to stop SCTLD. However, antibiotics, specifically amoxycillin, have been proven to stop the progression of the disease. The amoxycillin in powder form is mixed with a special marine epoxy and then administered to coral colonies through syringes. Depending upon the coral species, the efficacy rate can range between 60-80%.

How do I help?

This all sounds catastrophic, but there is hope. And you’re part of it. Here’s how you can help:

  • Decontaminate your gear. Pathogens can survive in scuba diving and snorkel gear. This can cause the disease to spread internationally. Help avoid this by soaking your gear in a solution of water with 1% bleach. Avoid further environmental contamination by allowing this solution to sit in the sun and breakdown for one day. Then dispose of it.
  • Remember the 3 Ts: Don’t Touch, Take or Tease. Touching diseased coral and then healthy coral can cause transmission of the disease. But this isn’t the only reason you shouldn’t touch the coral. Coral are actually fragile animals. If you touch them, kick sand in them or hit them with your instruments, fins or body, you can seriously harm them. Learn more about Coral Etiquette from the NOAA.
  • Volunteer for a Treatment Dive: At Sun Divers, one of our core values is to Always be Eco-Active. We believe that we’re not here just to enjoy the splendors of the ocean, but to protect them. One way we are acting as good stewards of the reefs, is conducting bi-weekly SCTLD treatment dives. Volunteer divers and local conservation agency staff from the Roatan Marine Park and Bay Islands Conservation agency, dive together to treat, tag, monitor and collect data on SCTLD. We have adopted two dive sites to focus and measure our efforts on: the beloved Blue Channel and Shallow Aquario. Learn more about how you canparticipate in these volunteer dives. 
  • Snap a photo! You’re scouting the reef for you next perfect underwater photography shot and then you see it: a bright yellow tag with numbers on it. That is an identification tag for coral colonies treated for SCTLD. While not your intended subject, snapping a photo of the tagged coral colony and sending it to the Roatan Marine Park is a vital way that you can provide visual data for the monitoring of SCTLD.
  • Support local conservation groups: In Roatan, SCTLD treatment efforts are being led by two non-profit organizations: The Roatan Marine Park and BICA. These organizations are authorized to purchase the marine epoxy used to administer the amoxycillin to corals and they do so through grant and private funding. Producing and shipping marine epoxy from Florida to Roatan can be quite expensive, so any amount of financial support helps. Learn more about how you can monetarily support SCTLD treatment through the RMP and BICA.
