Coral reefs are among the Caribbean’s biggest attractions. They support an extraordinary diversity of marine life while drawing millions of snorkellers, divers and cruise passengers every year. As coral reefs come under growing pressure, protecting them has become an increasingly important priority for cruise lines, particularly around private islands and exclusive beach destinations.
One of the greatest challenges is Stony Coral Tissue Loss Disease (SCTLD), a fast-spreading disease that attacks hard corals. First detected in Florida in 2014, SCTLD has now been identified in 33 countries and territories across the Caribbean. In severe cases, entire coral colonies can die within months, threatening marine biodiversity, coastal protection, fisheries and tourism.
Collaboration Across Borders
To help tackle the disease, more than 45 scientists, government representatives and marine conservation experts from The Bahamas, Florida and across the wider Caribbean recently gathered in Miami to exchange knowledge and discuss the latest research on SCTLD. The workshop, organised by the MSC Foundation, focused on strengthening regional cooperation and sharing practical solutions to better protect vulnerable coral reefs.
Participants agreed that international collaboration is essential. Coral diseases do not stop at national borders, making the exchange of scientific data, treatment methods and field experience crucial to slowing the spread of the disease and improving reef restoration efforts.
Why This Matters for Cruise Destinations
For the cruise industry, healthy coral reefs are far more than an environmental concern. They protect coastlines, provide habitat for countless marine species and remain one of the Caribbean’s most popular attractions for cruise guests enjoying snorkelling and diving excursions.
As a result, many cruise lines are investing more heavily in marine conservation around their destinations, often working alongside governments, researchers and environmental organisations. For companies operating private islands, protecting surrounding reef ecosystems is becoming an increasingly important part of broader sustainability strategies.
One example is Ocean Cay MSC Marine Reserve in The Bahamas, where environmental monitoring identified signs of SCTLD. Working with local authorities and scientific partners, treatment programmes have been introduced to help slow the disease and protect vulnerable coral colonies.
Priorities for Protecting Caribbean Reefs
During the workshop, participants identified five priorities to strengthen coral reef conservation in The Bahamas:
- expanding local conservation expertise and training;
- closing critical scientific knowledge gaps;
- strengthening collaboration between research institutions;
- improving understanding of reef connectivity;
- implementing integrated management strategies that address multiple threats facing reef ecosystems.
The organisations involved intend to build on these priorities through a shared framework aimed at improving long-term coral reef protection across the region.
