STONY CORAL TISSUE LOSS DISEASE
Since it was first reported in Florida in 2014, Stony Coral Tissue Loss Disease (SCTLD), has now spread throughout the Wider Caribbean Region with cases in Jamaica, Mexico, Sint Maarten, the U.S. Virgin Islands, the Dominican Republic, the Turks and Caicos Islands, Belize, Sint Eustatius, Puerto Rico, The Bahamas, the British Virgin Islands, the Cayman Islands, Guadeloupe, St. Lucia and Honduras.
SCTLD spreads rapidly and affects some of the slowest-growing and longest-lived reef-building corals, including the brain, star and pillar corals. Scientists are uncertain about the cause of the disease but it is water-borne and can be spread by contact. As the disease continues to spread throughout the Caribbean MPAConnect, a partnership between GCFI and NOAA’s Coral Reef Conservation Program, has developed resource materials that will help with the identification, monitoring and treatment of the disease, which may be found below.
SCTLD spreads rapidly and affects some of the slowest-growing and longest-lived reef-building corals, including the brain, star and pillar corals (Table 1).

Scientists are uncertain about the cause of the disease but it is water-borne and can be spread by contact. As the disease continues to spread throughout the Caribbean MPAConnect, a partnership between GCFI and NOAA’s Coral Reef Conservation Program, has developed resource materials that will help with the identification, monitoring and treatment of the disease, which may be found below.
MPAConnect has designed posters designed to increase awareness about SCTLD amongst natural resource managers and divers. Copies of the posters may be found below in English, Spanish and French.
This poster seeks to help Caribbean marine natural resource managers monitor, identify and mitigate against SCTLD.
Recreational divers may regularly dive the same reefs and explore areas that may otherwise not be monitored on a regular basis. This poster was designed to raise awareness amongst divers so they could identify possible cases of SCTLD and report it to the relevant authorities.
Since the disease can be spread through contact this provides divers with
information on how to reduce the likelihood of transmission.
Date: January 26, 2021
Time: 10AM – 12:30PM (EST)
Description: Presenters in this webinar will provide training on how to monitor for SCTLD, input and analyse the data. Real world experiences will also be shared by some of our partners from the Turks and Caicos Islands, Florida and the Grenadines.

A webinar on Identifying Stony Coral Tissue Loss Disease was hosted on September 15, 2020
In August 2019, MPAConnect’s 8th Peer To Peer Exchange provided natural resource managers from 17 countries/ territories in the Wider Caribbean Region with capacity building support to monitor and treat stony coral tissue loss disease.
