Report Stony Coral Tissue Loss Disease

What can we do to stop the spread of SCTLD
and protect our reefs?

Using the form on this page, you can submit up to 4 images of suspected SCTLD cases. Please provide the location of your sighting (a Google Maps URL), and share your contact information so we can contact you if we have further questions regarding your sighting.

What Else Can You Do?

Limit how the disease is transported by humans by disinfecting bilge water and dive/snorkel gear between dive sites using a mild bleach solution of hydrogen peroxide-based disinfectant.

Commercial ships must properly exchange ballast water by to prevent spreading the disease.

Report new locations where corals are showing signs of the disease. If we catch it early on a reef, we can prevent its spread to other corals on the reef.
