Deadly Coral Disease in Florida, Caribbean May Be Transported in Ship Hulls, Study Finds
Coral reefs are one of the most diverse and important ecosystems on the planet. They provide habitat for countless marine species, protect coastlines from storms and erosion, and support local economies through tourism and fishing. However, coral reefs are under threat from a variety of factors, including climate change, pollution, overfishing, and disease. In recent years, a deadly coral disease known as Stony Coral Tissue Loss Disease (SCTLD) has been spreading rapidly throughout the Florida Keys and the Caribbean, causing widespread coral mortality. A new study has found that this disease may be transported in ship hulls, highlighting the need for better biosecurity measures to protect coral reefs.
What is Stony Coral Tissue Loss Disease?
Stony Coral Tissue Loss Disease is a highly contagious disease that affects stony corals, including some of the most important reef-building species such as brain corals and pillar corals. The disease causes rapid tissue loss and can kill corals within weeks or months. SCTLD was first identified in Florida in 2014 and has since spread throughout the Florida Keys and into the Caribbean, affecting over 30 species of coral.
How is SCTLD Spread?
The exact cause of SCTLD is still unknown, but it is believed to be caused by a bacterial pathogen. The disease can be spread through direct contact between corals or through waterborne transmission. However, a new study published in the journal Frontiers in Marine Science has found that SCTLD may also be transported in ship hulls.
The Study
The study was conducted by researchers from the University of Miami Rosenstiel School of Marine and Atmospheric Science and the National Oceanic and Atmospheric Administration (NOAA). The researchers collected samples from ship hulls at ports in Florida and the Caribbean and tested them for the presence of the SCTLD pathogen. They found that 40% of the hulls tested positive for the pathogen, suggesting that ships may be transporting the disease from one location to another.
Implications for Coral Reef Conservation
The findings of this study have important implications for coral reef conservation. Ship traffic is a major source of marine bioinvasions, with ships transporting a wide range of non-native species around the world. The study suggests that ships may also be transporting deadly coral diseases like SCTLD, which could have devastating impacts on coral reefs in new locations.
To address this issue, the researchers recommend that better biosecurity measures be put in place to prevent the spread of SCTLD and other coral diseases. This could include measures such as hull cleaning and disinfection, ballast water treatment, and improved monitoring and reporting of disease outbreaks.
Conclusion
Stony Coral Tissue Loss Disease is a deadly coral disease that is spreading rapidly throughout the Florida Keys and the Caribbean. A new study has found that this disease may be transported in ship hulls, highlighting the need for better biosecurity measures to protect coral reefs. By taking action to prevent the spread of SCTLD and other coral diseases, we can help to protect these important ecosystems for future generations.
