The world's third-largest coral reef just off the Florida Keys was once a vibrant habitat for millions of plants and animals. But an outbreak of stony coral tissue loss disease is threatening to destroy it. Scientists are trying to regrow the coral in a lab hundreds of miles away to save it. Manuel Bojorquez takes a look.

Scientists from FWC and the The Florida Aquarium are experimenting with outplanting offspring of rescued corals back into the wild!

Studies show stony coral tissue loss disease doesn’t seem to impact smaller corals, but certain fish love to munch on newly outplanted baby corals. FWC is conducting experiments to find the best way to protect the corals from being eaten by fish. Will it be predator exclusion devices (our fancy way of saying “BBQ skewers arranged in a tent around the coral”)? Allowing the corals to acclimate in an in-ocean “nursery” to acquire natural chemical defense cues? Or have them lose some of their irresistible baby fat first? Stay tuned as the data comes in!

After finding suitable areas on the reef, creating the monitoring plots, mapping out the sites, and epoxying ceramic tiles to the reef that the coral outplants would be attached to, the experimental plots were ready for their corals. In early February divers braved the 68 degree waters and outplanted 463 corals of two species – boulder brain coral and grooved brain coral - onto two study reefs in the Middle Keys. Corals will be routinely monitored to document survival and predation rates between acclimated and non-acclimated corals and corals with and without predator exclusion devices.

Experiments like this are the next phase of the Coral Rescue Project – Propagation and Restoration. In areas of Florida’s Coral Reef where the disease has abated, the time may be right to start restoration efforts. Only experiments like these will tell us for sure.

All work done under NOAA Permit FKNMS-2021-224. Nails were installed in bare areas and will be removed at the end of the experiment.

Florida Coral Rescue Center Established to Help Save Florida Reefs: The Florida Coral Rescue Team led by FWC and NOAA Fisheries has rescued thousands of corals off Florida’s Coral Reef in response to the devastation caused by stony coral tissue loss disease. But what’s happened to these corals after they’ve been rescued? These coral “reefugees” are being held in 20 Association of Zoos and Aquariums (AZA) facilities and four non-AZA facilities in 14 states across the country, out of harm’s way from the disease.

Stay updated through our Coral Rescue dashboard.

We are happy to introduce our latest partner, the Florida Coral Rescue Center (FCRC) in Orlando. This state-of-the-art facility, created through a partnership between Disney and SeaWorld, is the nation’s largest caretaker of rescued corals. FCRC represents hope for the future of Florida’s Coral Reef, safekeeping over 700 corals from 18 species susceptible to the disease in 18 aquariums (5,800 total gallons) devoted to coral care. Corals kept at FCRC and all the Coral Rescue holding facilities will be used in land-based captive breeding programs designed to increase the genetic diversity and the number of corals we can return to the wild, significantly expanding our coral restoration potential. Some of the rescued corals have already been put into captive breeding programs and their offspring have been outplanted back to the wild. More on the FCRC

A big thank you to our partners at The Association of Zoos and Aquariums, Disney Conservation, SeaWorld, Fish & Wildlife Foundation of Florida, and NOAA Coral Reef Conservation Program for working together on efforts to save Florida’s Coral Reef!

Over the past few months, the FWC Coral Rescue Team has been collecting corals from two coastal construction sites: Fisher Island in Miami and the Port Everglades jetty in Fort Lauderdale. Both sites are located in an area known as the “endemic zone” -- a region of the Florida Reef Tract where stony coral tissue loss disease (SCTLD) has been present for >1 year and now maintained at baseline levels.

Golfball coral (Favia fragum), a SCTLD susceptible species, was collected at one endemic site and became a new addition to the list of Coral Rescue Project species. These small corals (adults are usually <2 inches) are rare along Florida’s Coral Reef and were not found in earlier collections ahead of the disease boundary, making endemic collections vital to preserving the species. From these two projects, 151 corals were rescued and now reside at the Reef Institute in West Palm Beach, FL and Nova Southeastern University in Dania Beach, FL.

These surviving colonies of SCTLD susceptible species from the endemic zone will provide potentially disease resistant genes to breeding activities in the Coral Rescue Project. Endemic corals will receive the same expert care as pre-invasion rescue corals but will remain biosecure and isolated to prevent any potential risks. Future collections are being planned at other coastal construction projects to preserve additional, genetically diverse, valuable corals from Florida’s Coral Reef.

From Rescue to Restoration – First rescue corals returned to Florida’s Coral Reef!

Last month, boulder brain corals (Colpophyllia natans) that spawned from rescued corals at The Florida Aquarium Center for Conservation were outplanted in Miami by Southeast Florida Coral Reef Restoration Hub and FWC divers.

The parent colonies were collected in 2018 as part of the Coral Rescue Project, a multi-agency effort to preserve genetic coral diversity in response to the multi-year stony coral tissue loss disease outbreak that has been causing widespread coral mortality along Florida’s Coral Reef since 2014.

The boulder brain corals spawned while in human care at The Florida Aquarium and were reared for 14 months prior to transport to the University of Miami for outplanting at three reef sites near Key Biscayne. Larger corals were outplanted as single colonies while smaller corals were outplanted in clusters of three to promote fusion and rapid growth while also reducing predation by fish. Outplants will be monitored for growth, survivorship, responses to environmental conditions, and potential exposure to stony coral tissue loss disease. This outplanting of 375 second generation corals (i.e., juvenile corals spawned from adult rescue corals) represents the very first rescue corals returned to Florida’s Coral Reef since the start of the Coral Rescue Project. Funding was provided by the National Fish and Wildlife Foundation.

It’s #WorldReefDay

Today we are celebrating Florida’s Reef Tract, also known as Florida’s Coral Reef. As the only living coral reef tract in the continental U.S., Florida’s Coral Reef spans 360 miles and is home to corals, sponges, fish, plants and other invertebrates. Currently this beloved reef is experiencing a serious challenge from a coral disease call the Stony Coral Tissue Loss Disease.

First documented in 2014, this disease has spread north and south affecting nearly all of Florida’s Coral Reef and is impacting over 20 different species of stony corals.

There is hope as FWC and partners have rescued over 1,600 corals from ahead of the disease front and has sent them to 18 different Associations of Zoos and Aquariums facilities across 12 different states. These healthy corals will serve as the parents of future generations of coral babies to be used for restoration of Florida’s Coral Reef.

If you would like to get involved with coral reef restoration and research activities, please join the Florida Coral Crew.

Late October, researchers from FWC, The Florida Aquarium and University of Miami's Rosenstiel School of Marine & Atmospheric Science conducted the last coral rescue cruise of 2019. Corals were collected from pinnacle reef sites near the Dry Tortugas National Park and 158 corals were delivered to the intermediate care facility at the University of Miami on Halloween. During 2019, a total of 1,573 corals were collected during three trips near Key West and five rescue cruises around the Marquesas and the Dry Tortugas. FWC’s Coral Rescue Team is extremely grateful to all 29 cruise participants who assisted in the rescue of Florida’s corals – that will be used for future coral restoration projects in response to the devastating Stony Coral Tissue Loss Disease.

Last week FWRI hosted the Coral Disease Technical Workshop where over 75 participants from multiple agencies and disciplines came together for two and half days to focus on coral disease research, intervention and restoration.

To date, over 1,400 coral colonies from Florida’s Reef Tract have been rescued ahead of the disease margin and housed at AZA facilities, to be cared for while partners continue to investigate Stony Coral Tissue Loss Disease (SCTLD).

FWC and partners just completed their latest coral rescue mission in a continued effort to combat stony coral tissue loss disease. Divers carefully collected 410 colonies from 15 species in the Dry Tortugas National Park, rescuing priority species to preserve genetic diversity and serve as breeding stock for future restoration efforts of the Florida Reef Tract.

Learn more about this rescue mission in our news release.

The Florida Reef Tract is under attack from a silent killer: stony coral tissue loss disease (SCTLD).

First documented off the Port of Miami in 2014 it has since spread to most of the reef tract affecting around half of Florida’s reef building coral species.

SCTLD is different from previous diseases in how rapidly it can kill an entire coral colony. An extensive multiagency effort is underway to track the spread of the disease, identify the pathogen, develop methods to lessen the effects of this disease on our reefs, and to rescue corals for safe keeping in zoos and aquaria around the country. These corals will be used to restore coral reefs once the threat of disease has been reduced.

This video shows a 10-day progression of SCTLD on a colony of Elliptical star coral harvested from a reef in the Lower Keys.

All work done under permits from the Florida Keys National Marine Sanctuary and FWC.

Efforts continue to rescue corals and preserve their genetic stock from the effects of the Stony Coral Tissue Loss Disease (SCTLD) event that has been causing massive mortality of over 20 species of Caribbean corals that call the Florida Reef Tract home.

FWRI staff were joined by partners from The Nature Conservancy, University of Miami, Nova Southeastern University (NSU), Mote Marine Laboratory & Aquarium, and NOAA Office of National Marine Sanctuariesfor a second rescue cruise to collect corals near the Marquesas Keys ahead of the SCTLD margin - currently located just west of Key West.

Divers carefully collected 341 colonies from 13 species at seven sites - all corals were measured, genetic samples collected, and each coral was tagged with a unique ID tag and mounted on tile. Large insulated bins holding 270 gallons of water were used to house the corals during the cruise and corals were secured within the bins using plastic shelving and small plastic baskets. Corals were delivered to NSU and transported directly to tanks where corals received an antiseptic dip to help remove potentially harmful bacteria or other unwanted competitors. After their dip, corals were arranged in shaded tanks to help control the temperature and light that the corals receive. Corals will remain at NSU until long-term housing at AZA facilities is available at which time corals will be boxed and shipped across the country.

To date, 1117 corals have been rescued and are located at nine AZA and research facilities.

FWRI and partners from NOAA Fisheries Service, University of Miami's Rosenstiel School of Marine & Atmospheric Science and Callaway Marine Technologies recently returned from the first coral rescue cruise into the Marquesas Keys, where they successfully collected 345 corals from 15 different species, including those most susceptible to stony coral tissue loss disease (SCTLD) - the event that causing mortality and drastic losses of coral along the Florida Reef Tract.

Corals were genetically sampled, measured, and carefully maintained in shaded totes during the 5-day cruise. The corals were directly transported by FWC Law Enforcement vessels to holding tanks at UM, where they will remain under the care until Association of Zoos and Aquariums facilities are available for long-term care.

Last week, FWC scientists collected 57 corals from a reef west of Key West – with species including flower, maze, and boulder corals. Each were carefully removed using hammer and chisel. These corals, plus 50 others collected earlier in the year, were transported to Mote Marine Laboratory in Sarasota.

While they are in aquaria, some of the corals will be used in breeding and coral fragmentation programs to increase the genetic diversity and number of colonies available for transplanting back into the wild.

An update from Mote reported the corals look good, with no signs of sickness. These corals will be kept at Mote until the SCTL disease passes and it’s safe to return them to the reef.

Rescued corals in an aquarium

Last month, 90 corals were transferred from Keys Marine Lab (KML) in Marathon, FL to their new home at Florida Aquarium’s Center for Conservation (FLAQ) in Apollo Beach–in response to the Stony Coral Tissue Loss Disease event currently affecting the Florida Reef Tract. This transfer frees up space at KML to allow for upcoming rescue collections.

Since September 2018, FWC staff have been successfully caring for rescued corals, with more than 99% still alive and healthy.

A diver underwater collects a coral sample

So far this week researchers have collected 88 corals, representing 10 species. Genetic samples were collected from each coral and reference markers will be developed to genetically sequence each species.

There has been very little genetic research conducted on many of the corals found in Florida and the Caribbean - so, not only have these collected corals been saved from potential mortality due to the disease event, researchers will now create a genetic registry for the corals, which will be hosted and managed by FWC.

Ensuring that genetic diversity is maintained throughout these collections will be paramount for future restoration efforts.

An underwater view of a diseased coral

This week, scientists from FWRI will be making their first field trip as part of a multi-agency team including National Oceanic and Atmospheric Administration (NOAA), NOAA Florida Keys National Marine Sanctuary and Florida Department of Environmental Protection, in an effort to rescue corals in South Florida.

Coral researchers are working to stay ahead of a disease event that is causing massive mortality of Florida’s coral reefs as far west as Looe Key. The stony coral tissue loss disease began in 2014 and has moved throughout the entire Florida Reef Tract, from Martin County to the Florida Keys.

Researchers will be collecting corals near Key West and temporarily storing them at the Keys Marine Laboratory before taking them to aquariums and research facilities around the country for preservation and research until the disease passes.
