Stony Coral Tissue Loss Disease
What is Stony Coral Tissue Loss Disease (SCTLD)?
Stony coral tissue loss disease (SCTLD) is a disease of corals that first appeared off the southeast coast of Florida in 2014. It originally was described as white plague disease. By 2019 it had spread along the Florida Keys and had appeared elsewhere in the Caribbean Sea. The disease destroys the soft tissue of at least 22 species of reef-building corals, killing them within weeks or months of becoming infected. The causal agent is unknown but is suspected to be either a bacterium or a virus with a bacterium playing a secondary role. Source: Wikipedia
A New study suggests that ship’s ballast water may pose a threat to continued spread. Source: University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science
Where can SCTLD be found?
The Atlantic and Gulf Rapid Reef Assessment page shows a map of where SCTLD is present in Florida. You can also submit basic and detailed bleaching and disease surveys.
What coral species are affected by SCTLD?
The Coral Disease and Health Consortium website has a list of which species are affected.
Can SCTLD be treated?
Yes, on a small scale. How To Treat Corals Affected by Stony Coral Tissue Loss Disease
Coral Bleaching
What is coral bleaching?
Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae (dinoflagellates that are commonly referred to as algae) that live inside their tissue, causing the coral to turn white. Source: Wikipedia
How can I track coral bleaching?
The Allen Coral Atlas can help you track coral bleaching.
Coral Restoration Efforts
What is Microfragmenting?
The Micro-Fragmentation technique consists of breaking the corals into smaller pieces of 1 to 5 polyps, using a specialised band-saw. This stimulates the coral tissue to grow, allowing them to grow into clones at 25 to 50 times the normal growth rate. Source: Ocean Gardener
What is Coral Stress Hardening?
Stress-hardening is one approach proposed to increase the thermal tolerance of coral genotypes currently grown for restoration. The Coral Program's heat stress resilience research will support the survival of coral reefs amidst warming sea surface temperatures and bleaching events. Source: NOAA
What is Assisted Evolution?
The term 'assisted evolution' (AE) refers to a range of approaches that involve active intervention to accelerate the rate of naturally occurring evolutionary processes. These approaches aim to enhance certain attributes such as temperature tolerance, growth or reproduction. Source: AIMS
