Grouper Moon: Conservation of Groupers in The Cayman Islands

January 2003 - December 2028


Participating Agencies

Many grouper species have seen declines in their populations driven by fishing targeting their spawning aggregations. The Cayman Islands have had a variety of protections in place with the goal of conserving their grouper populations. As a result of the protections in place and the relative ease of accessing the spawning aggregations, the Cayman Islands grouper populations can serve as study population for Caribbean grouper populations. The Grouper Moon Project was starting in 2003 as a collaboration between the Cayman Island Department of the Environment, Reef Environmental Education Foundation (REEF), and various university partners (Scripps Institution of Oceanography at University of California San Diego and Oregon State University) with the goal of providing the Cayman Islands government information on their grouper populations. The science products from this project will help inform management decisions and better understand the impacts from climate change on grouper populations.
