Coral Conservation Courses

To help replenish wild populations of corals, whether in areas where there has been a vessel grounding or areas where coral populations have declined due to major environmental events such as coral bleaching and winter cold water events, the Cayman Islands Department of the Environment has allowed Sunset Divers a permit to grow corals in underwater nurseries, specifically Staghorn coral.

Staghorn and Elkhorn coral can grow and reproduce through fragmentation; if a branch falls off on the reef and conditions are favorable, it can reattach to the rock and begin to grow a new colony. We take advantage of this naturally occurring process by growing corals in our offshore underwater nurseries until they are large enough to be out-planted on the reef.


In the nursery, the fragments are attached to PVC and fiberglass trees suspended off the seafloor. The rescued corals are cared for by staff and volunteers who monitor their health and growth and keep algae, encrusting sponges, and tunicates at bay.

There are currently 3 trees, each holding 100 fragments.  There is another tree that has nothing on just to the South, which is used as a quarantine tree, should something arise that we need to separate the fragments.

Coral Conservation Courses available at Sunset Divers

Guided Coral Nursery Dive (Discover Reef Renewal)

Join our dive staff on a guided Coral Nursery shore dive and become a Citizen Scientist for the afternoon.  Learn about the importance of Coral Nurseries here in Cayman and help maintain our Nursery by monitoring the trees for predators & disease.

$150 per person

















CoralWatch Distintive Specialty Course

Our unique Sunset House CoralWatch Diver Course is a methodology originally designed in Australia at the University of Queensland to monitor the health of the Great Barrier Reef. It has since grown into a globally co-operative network of citizen scientists and volunteers working together to collect real-time data to be used for combating, understanding, and aiming to reverse the negative effects of coral bleaching. This course will introduce budding citizen scientists to the knowledge, dive planning techniques, risk management and gripping enjoyment of completing CoralWatch surveys on the coral reefs encompassing Grand Cayman. The goals of this new course are to refine the student diver’s buoyancy skills, introduce scientific data collection techniques, and finally correlate these together with the input of the gathered data into the CoralWatch global database network. Every survey completed will make a difference in the future of our beautiful coral reefs, and it all starts with you.  Course includes a hands-on academic portion introducing the coral health chart which can then be put into action during the two ocean dives with your CoralWatch instructor.

$325 per person

All of the above courses are offered in conjunction with the ECO Divers Reef Foundation
