The Grouper Moon Project is a conservation science partnership between REEF and the Cayman Islands Department of Environment (DoE), with scientists from Scripps Institution of Oceanography at UC San Diego and Oregon State University. The project is aimed at studying Nassau Grouper, Epinephelus striatus, a keystone species on Caribbean coral reefs. Since 2002, our team has studied the Nassau Grouper spawning aggregations in the Cayman Islands, which hosts some of the largest and last known gatherings of this endangered fish. Our efforts have resulted in the successful recovery of Nassau Grouper populations in the Cayman Islands, and the project highlights the value of collaborative efforts for conservation success.
As the winter full moon approaches and we prepare for our annual field season, we wanted to share some of the highlights of Grouper Moon research findings over the last 23 years. Read on to learn more. You can also visit www.REEF.org/groupermoonproject to see details on education programs, scientific studies, and documentaries about the Grouper Moon Project.
One of the earliest scientific papers from the Grouper Moon Project was published in the journal Environmental Biology of Fishes in 2004. This paper documented the characteristics of the newly discovered Nassau Grouper spawning aggregation in the Cayman Islands. The authors provided visual and video documentation of four nights of spawning of Nassau Grouper, the description of the fish's nighttime movements and color phase shifts, and the documentation of courtship and spawning behavior in ten additional species. A few years prior to this paper being published, former REEF staff member Leslie Whaylen was leading a REEF Field Survey Trip in Little Cayman, around the same time that fishermen discovered the aggregation of Nassau Grouper off the west end of the island. As a result, approximately 2,000 fish were harvested in 10 days, from a population that was later determined to be approximately 9,000 fish. After meeting with the Cayman Islands government, the Grouper Moon Project was formed.
A few years later, in 2007, lead scientist for the project Dr. Brice Semmens, along with project partners, published a paper that explored why Nassau Grouper had declined so drastically in the Caribbean, and what could be done to reverse the trend. The discussion leaned heavily on early findings from the Grouper Moon Project. This study, titled "Charting a Course for Nassau Grouper Recovery in the Caribbean: What We’ve Learned and What We Still Need to Know" was presented at the 60th Gulf and Caribbean Fisheries Institute Meeting.
In 2020, almost two decades after the spawning aggregation was first discovered, a landmark paper was published in the prestigious Proceedings of the National Academy of Sciences that presented our findings of conservation success for endangered Nassau Grouper. Results of the analysis showed that on both Little Cayman and neighboring Cayman Brac, Nassau Grouper spawning aggregations have more than tripled in response to adaptive management by the Cayman Islands government over a decade. These management actions were a direct result of research conducted as part of the Grouper Moon Project.
The Grouper Moon Project is the Caribbean’s oldest continuous grouper spawning aggregation research program, and represents one of the most advanced, multi-faceted tropical fisheries research programs in the world. The project aims to support science-informed policies that will facilitate healthy grouper fisheries in the Cayman Islands in the coming years, while maintaining the Cayman Islands’ global leadership in collaborative tropical fisheries research and management. Since 2001, REEF and our collaborators have published 22 scientific papers sharing results from the research. You can see the full list of papers here.

Congratulations to Fred Hartner, who recently joined the Golden Hamlet Club! This distinguished group is made up of highly dedicated volunteers who have conducted 1,000 or more REEF surveys as part of the REEF Volunteer Fish Survey Project.
Fred first learned about REEF through the owner of his local dive shop in Whitehouse, New Jersey. He conducted his first survey in 1995 in Roatan, Honduras. Fred completed his milestone 1,000th survey in Key Largo, FL in November 2024, at Molasses Reef Ball 18. Before this special dive, mooring ball 18 was not named in the REEF database. In honor of Fred’s achievement, his wife, Laura, named the site Fred's Folly. Over the years, Fred has surveyed all over the world, collecting valuable marine life data across multiple regions. He is an expert surveyor in the Tropical Western Atlantic (TWA), Central Indo-Pacific (CIP), and South Pacific (SOP) regions, and has also contributed surveys in the Indian Ocean & Red Sea (IORS) and Hawaii (HAW) regions. Some of Fred’s favorite fish include the Peppermint Basslet, Purple Reeffish, and all types of cardinalfish. He also has a fondness for (invasive) lionfish, but only when they’re on his dinner plate!
Congratulations Fred, and thank you for your contributions to REEF and citizen science! Click here to read more about the Golden Hamlet Club.

REEF members are the heart of our grassroots marine conservation programs. A diverse community of divers, snorkelers, and ocean enthusiasts support our mission to conserve marine environments worldwide.
This month we highlight Edgar Graudins, a REEF member who lives in Washington. Since joining REEF nine years ago, he has conducted more than 140 surveys and achieved Expert Level status in the US Pacific Coast & Canada (PAC/PNW) survey region. We're thankful to Edgar for his dedication to conservation and passion for REEF's mission!
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
I first joined REEF in 2016. I heard about REEF from members of my dive club, the Emerald Sea Dive Club, and my local dive shop, Evergreen Dive Service, a REEF Conservation Partner. They helped me get started with surveying and directed me to learning resources.
If you have been on a REEF Field Survey Trip, where and what was your trip highlight?
I have been able to participate in the REEF Advanced Assessment Team surveys in the Puget Sound for the last few years. It's great to work with fellow fish geeks who are just as passionate about REEF as I am.
What inspires you to complete REEF surveys? What is the most interesting thing you’ve learned doing a REEF fish survey?
Being able to identify the different fish species makes my dives more interesting, and being a REEF member motivates me to keep improving my ID skills.
What is your favorite part about being a REEF member?
While growing up, I was going to be either a marine biologist or an engineer. I ended up going the engineering route for my profession, but I never lost my interest in the marine world. Being a REEF member and doing surveys gives me the opportunity to feed my other passion by being a citizen scientist in my spare time.
In your opinion, what is the most important aspect of REEF’s projects and programs?
One of the most important aspects of REEF is involving the public in science. The wide network of citizen scientist divers around the world not only helps collect data, but they also become passionate advocates for marine conservation.
Do you dive close to where you live, and if so, what is the best part about diving there?
Living in Washington State, I am fortunate to have the entire Puget Sound on my doorstep. I dive year round in the Sound (even in winter!) and have a bunch of great dive sites within an hour of my house. This area has a wide variety of diving environments including eelgrass, kelp forests, natural reefs, artificial reefs, wrecks, and walls, each with its own variety of life. Diving Puget Sound never gets old.
What is your favorite fish or marine invertebrate?
I love the Mosshead Warbonnet. It has fantastic colors and patterning, and makes a great photo subject. Also, it likes to hide and is hard to spot, so when you do find one, you feel a sense of accomplishment.
Do you have any surveying, fishwatching, or identification tips for REEF members?
Practice, practice, practice! Find what method you learn best with - watching Fishinars, studying fish ID books , flash cards, or whatever - and just keep doing it regularly.
What is your most memorable fish find?
I once spotted a Redstripe Rockfish, Sebastes proriger, at one of my local dive sites. That species is rarely seen by divers and even more rarely reported - partly because it is very similar to another, more common species. Had I not been studying for my REEF Level 5 test that year, I probably would not have recognized it.
