REEF scientists and volunteers just wrapped up another season of the Grouper Moon Project, a collaborative research effort with the Cayman Islands Department of the Environment (CIDOE). Our research focuses on Little Cayman, which has one of the largest (and one of just a few) known spawning aggregations of Nassau Grouper in the Caribbean. Over 4,000 grouper amass in one location for 7-10 days following winter full moons. Our team went to Little Cayman around full moons in both January and February this year (both because it was considered a “split year”, meaning the full moon dates were right on the line of predicting which month would be the strong spawning month). February turned out to be the big month, and spawning was seen over 3 nights starting 3 nights after full moon. Watch a short video montage of the aggregation and spawning action here - http://youtu.be/GwKVzPLgmbo
Since 2002, REEF and our partners at CIDOE, Scripps Institution of Oceanography, and Oregon State University have used a variety of research techniques from diver surveys to state-of-the-art technology to study this amazing natural phenomenon. The research has yielded ground-breaking results that have led to improved conservation for Nassau Grouper in the Cayman Islands. This year, we tested out some new techniques for collecting and rearing fertilized eggs (in the montage video you will see a diver swimming through a spawn cloud with a plastic bag). After collecting Nassau grouper eggs during the two nights of peak spawning, Scripps scientists and REEF Grouper Moon Project volunteers cultured the eggs at the Central Caribbean Marine Institute on Little Cayman. After one night, a subset of eggs were preserved for research on fertilization rates. After two nights, the eggs had hatched, and researchers were surprised to find larval Nassau swimming around the tank the next morning. Check out this video of larval Nassau grouper under the microscope - http://youtu.be/0Vph6LzH9IE
In addition to the research, REEF also is leading the charge on an educational program surrounding Nassau Grouper and spawning aggregations. Thanks to support from Disney Worldwide Conservation Fund, we have created an exciting K-12 education curriculum rooted in the link between healthy reef communities (including humans) and healthy spawning aggregations. See last month's REEF newsletter for more about the Grouper Education Program.

Many Thanks! The Grouper Moon Project wouldn’t be possible without the dedication, passion, and financial support from many individuals, Cayman Island businesses, and foundations. It truly takes a village to pull off this conservation research project. In 2014, we especially appreciate the continued generous logistical support provided by Peter Hillenbrand, local lodging and dive operators Reef Divers & Little Cayman Beach Resort and the Southern Cross Club (especially Neil van Niekerk and the crew of the Lucky Devil for taking our team out in January), and Brac Reef Resort. Funding from the Disney Worldwide Conservation Fund supported field efforts and the Grouper Education Program. LIME Cayman Islands has provided support for the live-video feeds for the Grouper Education Project since 2012. Cayman Airways provided inter-island travel support. And the staff at Central Caribbean Marine Institute provided research space for the fertilized egg work. Thanks also to our scientists, volunteers, and partners who made this year's efforts possible - Adam, Alex, Brenda, Bradley, Croy, Guy, Hal, Ivan, James, Josh, Keith, Leslie, Laura, Lynn, Paul, Steve, and Todd.

We are excited to announce a new expansion of the Volunteer Fish Survey Project to the eastern Atlantic, beginning with a new program in the Azores. REEF's Director of Science, Christy Pattengill-Semmens, Ph.D., spent time in the islands earlier this summer developing new survey and training materials. This Portuguese archipelago is the northern extent of a bioregion known as Macaronesia, which also includes Madeira, the Canary Islands, and the Cape Verde Islands. The underwater habitat features volcanic rocky reefs and common fish species include colorful wrasses, damselfish, sea breams, and pelagic rays.
The new REEF program will include the standard fish survey protocol as well as an invertebrate and algae monitoring component. The expansion is in collaboration with the local government agency, Direção Regional dos Assuntos do Mar, as well as the University of the Azores, Observatório do Mar dos Açores, and Parques Naturais de Ilha. We expect to offiically launch the new region later this year.

This summer seemed to fly by, and along with it went REEF’s 2016 Summer Lionfish Derby Series! It was an exciting summer full of “firsts” for the derby program. We added a fourth derby to the series, which we hosted in Sarasota in partnership with Mote Marine Laboratory & Aquarium. We also hosted our first Lionfish Culinary Competition in conjunction with the Palm Beach County Lionfish Derby, held at Loggerhead Marinelife Center, with support from the NUISANCE Group and Chef Chris Sherrill. The Sarasota and Palm Beach County derbies were full weekend events rather than single day removals, which gave competitors more time to get to sites that aren’t fished as often and to maximize the amount of lionfish removed. To top it all off, the Fort Lauderdale Derby teams brought in an astounding 1,250 lionfish in a single day! In all, the teams removed 2,426 lionfish during the REEF Lionfish Derbies in 2016. A whopping 18,560 lionfish have been removed in all REEF Derbies since 2009. Way to go teams. More stats below.
2016 Summer Series Derby Stats
Total Lionfish Removed:
Sarasota (July 9th & 10th) = 429
Fort Lauderdale (July 16th) = 1,250

REEF is asking any interested REEF members to submit to us a Field Survey T-shirt design for our upcoming 2008 season. Those of you who have participated in the past on a REEF Field Survey know that you receive a t-shirt as part of your participation in the program and every year we have a different design. There are only a couple of guidelines for you. Our new REEF Shirt must incorporate our REEF flag with our slogan, Diving That Counts! (I will send interested parties the jpeg file upon request). You do not need to incorporate the dive flag directly into the design, it may simply be on the front breast pocket of the t-shirt, for instance, with your design on the back and in this case, no need to ask
for our logo, we'll take care of that.
You should keep in mind our mission as stated on the top of our homepage, and our mantra, "diving that counts." Also please keep in mind that REEF actively surveys in 5 regions, not just the tropical western Atlantic. Please send your submissions to firstname.lastname@example.org, making sure they are in an easily readable format such as a jpeg file (preferred). Please send all entries in by Dec. 31, 2007.
Depending on the number of submissions we receive, we may have our members vote on the winner in January of 2008. Past t-shirts have had fish images, divers surveying, cartoons depicting divers surveying with witticisms, watercolors of fish, etc. Most importantly, our t-shirt design should incorporate the conservation-based focus of our Field Survey Program.
Thanks in advance for your participation and our staff will look forward to your entries. First prize will be a signed and framed 2008 Paul Humann print of two beautiful Eagle Rays.
Field Survey Season 2008 - 5 Spaces are still available for our Turks and Caicos Liveaboard on Aggressor II, April 19-26, 2008.
Please contact Travel for You at 1-888-363-3345 or Joe Cavanaugh at 305-852-0030. The 2008 Field Survey page will be completed shortly - please check back in a week for final content.
Thanks to a three-year grant from the Lenfest Ocean Program at the Pew Charitable Trusts, REEF and collaborators at the Cayman Islands Department of the Environment (CIDOE) and Oregon State University (OSU) will greatly expand the conservation science research being conducted as part of the Grouper Moon Project in the Cayman Islands. The funded research, entitled "The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management" will evaluate the potential for spawning site MPAs to recover Nassau grouper stocks.
In 2003 the Cayman Islands government protected all five known current and historic Nassau grouper spawning sites in the Cayman Islands. This move was motivated by the 2001 discovery and rapid depletion of a large spawning aggregation (~7000 fish) on the west end of Little Cayman. This rapid legislative response protected the west-end spawning site before all the fish were taken (~3,000 remain), and the site is now one of the largest fully-protected Nassau grouper spawning aggregations in existence. However, the other four spawning sites had previously been fished to exhaustion and are believed to be inactive, i.e. aggregations no longer occur during spawning season.
Over the next three years, REEF will continue the ongoing aggregation monitoring and acoustic research that has been conducted on the Little Cayman aggregation since 2002 and expand efforts to Cayman Brac and Grand Cayman, where historical spawning aggregations were fished out during the last ten years. Four primary research questions being asked as part of the Lenfest-funded project are: 1) Do aggregations form in regions that have been fished out? 2) If aggregations form, do the fish ultimately spawn? 3) Do these aggregations form at historic sites or somewhere else? And, 4) Does spawning at these remnant aggregations result in new recruitment?
The new research kicked into gear last month with a team of Grouper Moon scientists and REEF volunteers who conducted twelve days of field work in Little Cayman and Cayman Brac. The team visually monitored the Little Cayman aggregation, documenting the largest number of fish since the fishing ban was implemented in 2003. Spectacular mass spawning was documented at dusk seven days after the full moon. Grouper Moon scientists conducted extensive work on Cayman Brac to enable future visual monitoring on the historical aggregation site and initiate an acoustic tagging study that will facilitate a better understanding of the behaviors of Nassau grouper on an island with a limited number of reproductively-aged individuals. Later this Spring and Summer, REEF researchers, volunteers and an OSU graduate student will return to the Cayman Islands to conduct larval recruitment studies and begin acoustic tagging on Grand Cayman.
Capitalizing on the the increased breadth of research questions being asked as part of the Lenfest Ocean Program grant, the CIDOE is supporting a larval dispersal study that also kicked off this year under the guidance of Dr. Scott Heppell from OSU. Three satellite drifters were deployed at the Little Cayman aggregation site on the night of spawning. The paths will be recorded by ARGOS satellites for 45 days and the resulting data will be used to develop a larval dispersal model in collaboration with researchers from University of Miami. Check out the 2008 image gallery to see where the drifters are today.
REEF extends a big thank you to the island business who continue to support this project, including the Little Cayman Beach Resort and the Southern Cross Club, as well as Peter Hillenbrand and Mary Ellen Cutts, Franklin and Cassandra Neal, and the 2008 REEF Volunteer Team -- Judie Clee, Brenda Hitt, Denise Mizell, and Leslie Whaylen. We also greatly appreciate the continued support of our collaborative team, including the CIDOE and OSU, and the Lenfest Ocean Program at the Pew Charitable Trusts.
