Changing Seas: Grouper Moon

Researchers from the Cayman Islands Department of Environment and the Reef Environmental Education Foundation are studying one of the last great reproductive populations of Nassau Grouper. Normally a solitary species, during the winter full moons Nassau Grouper travel, sometimes over great distances though never across open water, to “group” together and spawn. While most of the known spawning sites in the Caribbean have been fished out over the years, the west end of Little Cayman in the Cayman Islands is home to the largest known reproductive spawning aggregation of this endangered species.
