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). In it's 15th year, this important project focuses on 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.
Several interesting video clips and stories from the field were posted on REEF's Facebook page. Be sure to check it out and like our page to keep updated on all REEF's programs.
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.
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 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 2016, we especially appreciate the continued generous logistical support provided by Peter Hillenbrand, and local lodging and dive operators Reef Divers & Little Cayman Beach Resort and the Southern Cross Club. Funding from the Disney Conservation Fund supported field efforts and the Grouper Education Program. FLOW 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, REEF volunteers, and partners who made this year's efforts possible. It's impossible to list everyone here - please visit the Grouper Moon page to see the full list - www.REEF.org/groupermoonproject.

On Saturday, July 14th, seventy members of the REEF Sustainers Club (annual donors of $1,000 or more), key partners and long-time REEF friends convened in Key Largo, Florida to celebrate fourteen years of REEF accomplishments over some diving and a sunset dinner. Paul Humann, Ned DeLoach and other Board, staff and Advisory Panel members were on hand to lead guests on some spectacular morning REEF survey dives while Amy Slate and her stand-up staff at the Amoray Dive Resort generously hosted the lodging and dinner party. “The event was just beautiful.” Said long-time REEF surveyor Elaine Morden, of Homestead, Florida. “It was great to connect with old REEF friends and see some new faces.”
The bi-annual Sustainers Event is a chance for REEF to bring together important members of the REEF family to thank them for their contributions and share successes of the organization over the years. This year, REEF was proud to recognize Linda Schillinger for achieving one of the highest REEF honors: admission into the Golden Hamlet club for those who have conducted 1,000 or more REEF surveys. We were also proud to recognize Key Largo resident and REEF office volunteer Audrey Smith for nearly ten years of regular service to the organization by quality-checking survey scanforms before they are uploaded to the REEF database. REEF was itself bestowed with an honor by Sanctuary Friends of the Florida Keys Director Glenn Patton: SFFFK generously gave a gift of support for the Great Annual Fish Count this year to help underwrite the costs of public outreach and education events.
By virtue of a Paul presentation and applause vote, the group answered the perennial question “What is the most beautiful fish in the Caribbean?” Out of thirty possibilities ranging from the spotfin hogfish to the fairy basslet, the spotted eagle ray won a narrow victory over close rivals the queen angelfish and queen triggerfish. Ned enthralled the group with fish behavior anecdotes from as far afield as Indonesia and gave updates on valuable REEF programs ranging from the Grouper Moon Project to the Exotics Species Sightings Project.
All agreed that the only thing hotter than the event itself was the Florida sun in July. With the heat index topping 100 degrees, no one needed a better excuse to indulge in a new REEF-inspired cocktail, the Indigo Hamlet, a unique and diversified alcoholic concoction for our wonderful sustainers to imbibe in while enjoying the sunset! Many thanks to all who made this a Sustainers Weekend to remember. See you at the next one . . .

Here are a few notes and news bits we'd like you to know about:
Four spots recently opened on our Turks and Caicos Field Survey aboard the Aggressor II, April 19-26, 2008. This is a wonderful opportunity for new and experienced REEF surveyors to spend a week diving in one of the jewels of the Caribbean. You can take advantage of our live-aboard accomodations and make up to 5 dives per day at all the best sites these islands have to offer.
There are quite a few expert surveyors on this trip, so if you're a beginning surveyor, you'll have plenty of mentorship and you could even work toward becoming an expert by the end of the week. For our experts, there are many cryptic species to challenge us on our surveys. We will have a number of REEF Fish ID classes and time to catch participants up on the many exciting upcoming REEF projects worldwide for 2008.
To reserve your spot - please call Joe Cavanaugh at 305-852-0030, ext. 3 or Tami Gardner at Travel for You, 1-888-363-3345, For more information about the trip, please visit our Field Survey page atField Survey page Hope you can join us!
In response to the growing threat of lionfish in the Atlantic and the need for coordinated planning, REEF, NOAA and the USGS are hosting a technical workshop on Non-native Marine Fish Introductions of South Florida in the Florida Keys June 18 and 19. The workshop, jointly funded through a recent Mote Marine Laboratory’s Protect Our Reefs grant, NOAA’s Exotic Species and National Marine Sanctuary Programs and the Gulf and Atlantic States Regional Panel on Aquatic Invasive Species,will bring together personnel from more than 18 different agencies and organizations. Plans for the workshop include presentations by State and Federal agencies, breakout groups and round table discussions that will focus on disseminating the most current information, and drafting a coordinated plan of early detection, notification, and rapid response.
Lionfish have been recorded in large numbers from North Carolina through the Bahamas and are rapidly expanding into the Caribbean. Fortunately, the fish have not yet shown up in the southeast Florida reef tract including Biscayne National Park, the Florida Keys National Marine Sanctuary and the Dry Tortugas National Park and Ecological Reserves. This planning workshop will endeavor to put in place mechanisms to help minimize lionfish impact in these treasured marine protected areas. While lionfish are the “poster fish” of invasive species, the protocols developed in this workshop will be widely applicable for sightings of other non-native marine fish as well, with the goal of preventing future invasions by other species.
REEF will continue to host training and planning workshops, as funding allows, to help downstream countries plan for the arrival of lionfish. Efforts to control populations and minimize impactswill be highlighted as research answers key questions and we are able to develop control methods. To find out more about REEF's Exotic Species Program, contact Lad Akins, Director of Special Projects.

Needed -- a few more volunteers for this critical marine conservation project in Belize! Peter Hughes and REEF’s Lad Akins will lead this great project aboard the livaboard dive vessel Sun Dancer II, June 13-20. I am sure that most of you have been following the news about the lionfish invasion and the recent updates on fish beginning to show up in Belize. We are really concerned about this. The Central American coast is going to be the most likely pathway for introduction of the fish into the Gulf of Mexico and the extremely valuable fish and shrimp industry there.
What can we do? One of the first things that can be done is early detection and rapid response to remove these fish as they show up. To that end Peter Hughes Diving has worked with REEF to organize the first lionfish assessment and removal project in Belize (or anywhere in Central America for that matter!). This is going to be a great first effort on detecting fish, removing what we see and training local staff on how to collect and handle the fish so they can remove them year-round.
What do we need? We need more of you! We need your interest, expertise and involvement to make this project a success. We know that times are tight and there is concern over travel to some areas, but this project is not to be missed. We will be offshore on the Sun Dancer II, one of the most highly regarded liveaboards in the region. First class service, first class diving and a very important mission!
We hope you can make this project! For more information and to sign up, call Peter Hughes Diving at 1-800 9 DANCER (800-932-6237). You can also contact REEF Director of Special Projects, Lad Akins, with any of your lionfish questions and to find out more about this trip (firstname.lastname@example.org, 305-852-0030).
We look forward to seeing you there!
Active REEF surveyor, Mike Bear, and other San Diego area divers started noticing something unexpected earlier this year -- increasing numbers of encounters with the Bluntnose Sevengill Shark, Notorynchus cepedianus, also known as the Broadnose Sevengill shark. Knowing first hand the impact that divers and snorkelers can have as citizen scientists, Mike set up a website - http://sevengillsharksightings.org -- to serve as a central repository for photographic, videographic and written data on these magnificent creatures. Submissions on the site will allow REEF surveyors who are lucky enough to encounter this prehistoric species to provide additional information and images beyond the sighting and abundance information recorded as part of their REEF survey. It will also enable divers who were not doing a REEF survey to report their encounter. One of the most interesting parts of the website will be the development of an informal photographic database of Sevengill sightings that will facilitate the comparison of photographs and the potential identification of individual sharks using the unique pattern of dark "freckles" on the backs of each shark, similar to the patterns seen on whale sharks. To date, six REEF surveys in San Diego have reported a Sevengill (click here to see the sightings report).
The second annual Abaco Lionfish Derby, held at Green Turtle Cay, Bahamas, on Saturday June 19th, was a huge success. Teams on twenty-one boats from Florida and the Bahamas enjoyed perfect weather and conditions while collecting a grand total of 941 lionfish. Over $5,000 in cash was awarded to the winning teams for the most, biggest, and smallest lionfish. This event, held in the Bahamas and sanctioned by the Bahamas Department of Marine Resources, is one of many REEF efforts to cull invasive lionfish populations and raise awareness about the issue.
The award for most lionfish collected in the one-day event went to team White Roach from Abaco. Repeat winners, the trio of skilled lionfish collectors significantly exceeded their tally from 289 lionfish last year to a whopping 345 this year. This number is both astonishing and alarming when you consider how dense lionfish populations must be for three people to have the ability to collect over 300 lionfish in the span of a single day.
Team Meander from Jacksonville, FL, clenched 1st, 2nd, and 3rd place for largest lionfish collected. Zane Carney captured the largest lionfish ever recorded in the Abacos, which measured just 2cm short of the national record. Zane told Derby organizers that he found a hole outside the main barrier reef off of No Name Cay in 45 feet of water that was full of very large lionfish. He used a pole spear to bag the winning fish, which was 43.4 cm in length (roughly 19 inches long) and weighed approximately 4 pounds.
Lad Akins, REEF’s Director of Operations, and Stephanie Green, a collaborative research partner from Simon Fraser University, recorded valuable data during the event, including lionfish sizes, stomach contents, and sex for many of the lionfish before they were filleted and cooked by the Green Turtle Club. Observers and participants, many of whom had never tried lionfish, found the fish quite tasty, resembling hogfish or grouper. This year, Tropic Seafood Limited of Nassau also arranged to purchase some of the larger fillets of lionfish for distribution in local markets. According to Derby organizer, Bobbie Lindsay, “Tropic’s offer to purchase lionfish is an exciting development, because creating a market for lionfish is the best way to control the population of this invasive fish.”
Thanks to the Derby co-sponsors, Green Turtle Club, and Brendal’s Dive Center, who offered special discounts for Derby participants. REEF also extends sincere gratitude to all of the participants, and especially Bobbie Lindsay, an active REEF member and volunteer who took the lead in organizing the Derby making it a successful event again this year. Next year’s Derby is set for June 24-25, 2011. For full results and pictures go to www.lionfishderby.com.
