Honoring Our Golden Hamlet Club Members

No, it's not a club of Shakespearean enthusiasts! Rather it's a club of citizen scientist superstars - those REEF members who have conducted 1,000+ surveys in the REEF Volunteer Fish Survey Project. The very first Golden Hamlet member was Linda Baker, achieving the status in 2005. Today, there are are sixteen members of the Golden Hamlet Club. We recently created a plaque, now hanging at REEF HQ in Key Largo, with the names of our honored volunteer surveyors -- Lad Akins, Linda Baker, Judie Clee, Janet Eyre, Dave Grenda, Doug Harder, Lillian Kenney, Peter Leahy, Rob McCall, Franklin Neal, Mike Phelan, Bruce Purdy, Linda Ridley, Dee Scarr, Linda Schillinger, and Sheryl Shea. Congratulations to you all. Thanks to their dedication, and those of the 14,000 other volunteers who have participated in the Survey Project since its inception in 1993, we have generated the largest marine fish sightings database in the world. Who's going to be the next Golden Hamlet surveyor?

Grouper Moon Scientists Talk Live with School Children From Under the Waves

Grouper Moon researchers, Brice Semmens, Christy Pattengill-Semmens, and Steve Gittings, join educator, Todd Bohannon, for a live-from-the-field chat with Caymanian classrooms. They explained a typical research day and showed much of the research equipment used.

It was a science lesson with a difference, broadcast live from beneath the waves with thousands of endangered fish in attendance. Earlier this month, Grouper Moon Project scientists, Dr. Brice Semmens from Scripps Institution of Oceanography, and Dr. Christy Pattengill-Semmens from REEF, hosted three live-from-the-field web chats with students from 18 classrooms at 13 schools in the Cayman Islands, The Bahamas, and Washington State (US). The first of the three web chats was broadcast from the Grouper Moon base of operations on Little Cayman, and featured scientists explaining the research objectives, day-to-day activities, and research equipment used during the project. The other two featured Brice diving and answering questions from the students, first on the Nassau Grouper spawning aggregation and then on the famous Blood Bay Wall. The webcasts are archived online here.

Now in its third year, the Grouper Education Program presents students with a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important species. Key curricular concepts include: the historical role of Nassau Grouper in the Caribbean, its role as a top predator and its positive impact on local reef health, and the conservation challenges facing the species.

Brice Semmens, who presented the underwater webcasts, said students were excited to witness science in action. “As they explore the aggregation with me, the immediacy and reality of the experience really touches them. We are giving students their first diving experience – and it happens to be with thousands of huge, endangered reef fish.”

The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support is provided by Southern Cross Club, Little Cayman Beach Resort and Reef DiversCayman Airways, and LIME.

Putting It To Work: New Publication on Effectiveness of Lionfish Culling

REEF staff co-authored a new publication in the scientific journal PeerJ that features research findings from our Invasive Lionfish Research Program. The paper, titled "Setting the record straight on invasive lionfish control: Culling works", evaluates the effectiveness of lionfish removal efforts. Frequent culling of the invasive Indo-Pacific Lionfish throughout the Caribbean has been shown to cause a shift towards more wary and reclusive behavior by lionfish, which has prompted calls for halting culls. The paper addresses those concerns and reviews research conducted by REEF and other efforts. Culling successfully lowers lionfish numbers and has been shown to stabilize or even reverse declines in native prey fish. Partial culling is often as effective as complete local eradication, yet requires significantly less time and effort. Abandoning culling altogether would therefore be seriously misguided and a hindrance to conservation. The authors also offer suggestions for how to design removal programs that minimize behavioural changes and maximize culling success. The paper is available for online viewing here. You can find a complete listing of all publications that feature REEF's programs at www.REEF.org/db/publications.

Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:

- A scientist from Bermuda Institute of Ocean Sciences (BIOS) requested REEF data to evaluate fish assemblages in Bermuda with regard to no-take reserves, comparing shallow vs. deep water habitats, and to evaluate the impact of invasive lionfish.

- A scientist from Washington State Department of Transportation requested REEF data to help evaluate the impacts of a proposed ferry terminal at Keystone Jetty on three species of protected rockfish.

- A graduate student from University of Miami requested REEF data from New Providence, Bahamas, to compare the measures of rugosity used in various research research methods and their ability to predict fish diversity and abundance.

A complete list of scientific publications featuring REEF programs and data can be found at www.REEF.org/db/publications.

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.

Bermuda - a Unique Destination

The Grotto Bay Resort, home to the Bermuda REEF Field Survey this October.

Bermuda is at the northern extent of the Tropical Western Atlantic survey region and represents a unique destination for REEF's fish watchers. There are six spaces left on our Field Survey Trip to Bermuda (October 1-8), and this is your opportunity to dive pristine reefs, expand your knowledge of marine life, and search for elusive and beautiful fish such as the redback wrasse. Trip leaders Ned and Anna DeLoach will entertain participants with their fish identification and behavior expertise, providing engaging lectures and photographs in conjunction with educational seminars each evening. Pink sand beaches, fascinating historic sites and a blend of British Colonial and African culture help to make Bermuda, also known as the "Jewel of the Atlantic," a captivating destination for non-divers as well. Check out the full trip description at www.REEF.org/trips.

Even if you can't make the trip, be sure to join Ned and Anna online for their free Fishinar at the end of this month, August 30. See www.REEF.org/fishinars for all the details.

Playing Virtual Darts With Fish ID

A group of REEF surveyors in Mexico have set up a study group on “WhatsApp” (a mobile device chat app) to prepare themselves for REEF Level 2 tests in the Tropical Eastern Pacific (TEP) region. The group is coordinated by Itziar Aretxaga, who recently passed level 3 in that region and is a Level 5 expert in the Tropical Western Atlantic (TWA). Members of the group live throughout Mexico, but stay connected and learn together through a game of virtual darts on their mobile phones. Every day they are presented with a problem fish they have to solve, and at the end of the day the recognition card for the fish of day is sent with instructions of names in English and Spanish and features to look for.

Along with the daily mystery fish, the participants are playing a rolling game over the course of two months in which one participant “throws a dart” with a photograph to another participant to recognize. The recipient has a maximum of 24 hours to reply. If the recipient identifies the species, he/she receives 1 point. If the reply is incorrect, the recipient receives -1 point. If the sender misidentifies the species for one that is not in the study cards already seen, he/she receives -2 points. If anybody other than the recipient replies within the 24 hr period, he/she receives -2 points. If the recipient does not reply within 24 hours or replies incorrectly, the dart can be picked up by any participant, and points are assigned to the one that first replies with the correct answer. The score is normalized by the number of darts aimed at each participant and the final prize is a round of beers paid by the participant who scores less points.

The group has been playing fish-darts for three weeks now, and is having quite a blast with 35 cards already studied and almost 40 darts sent in the game. Negative points have been assigned mainly for misidentifications of photographs found with Google on the internet. In two weeks, when they complete the 50 species they have set for themselves to study, they will declare a winner and the person in charge of beers for all. ¡Salud!

The Faces of REEF: Dottie Benjamin

REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.

This month we highlight Dottie Benjamin, a REEF member since 1996! After living on Little Cayman for years, Dottie moved to North Carolina a few years ago. During her time in the Cayman Islands, she was involved in REEF's Grouper Moon Project and she also found a possible new species of fish! Dottie has conducted 75 surveys and is a Level 5 Expert Surveyor in the Tropical Western Atlantic (TWA). Here's what Dottie had to say about REEF:

When and how did you first hear about REEF? I first learned about REEF while working in Belize as a Dive Instructor and a REEF Field Survey was taking place at my place of work. Ned & Anna DeLoach were the presenters and I became fascinated with the names and behavior of all the little critters that I was seeing on a daily basis. I learned all kinds of fun facts and the fishy bug bit. Moving to Little Cayman – I had the pleasure of getting to know Judie Clee (1000+ surveys) and she reinforced my love of fishes and shared in my excitement at finding a tiny Goby or Blenny. She helped me achieve my Level 5 TWA rating and got me interested in teaching others about all the incredible diversity under the waves.

What is the most fascinating fish encounter you’ve experienced? Living in Little Cayman for 18 years, I was honored to help with REEF's Grouper Moon Project and being able to swim with 3000+ groupers during their annual aggregate spawn is simply breath-taking. And your diving career is not complete until you have had the chance to rub the cheeks of a big old friendly Nassau Grouper. They are amazing creatures.

Do you dive close to where you live, and if so, what is the best part about diving there? I now live in North Carolina and dive & work at Olympus Dive Center… the fish are a little different, but once you know your fish families… you can figure out what you are looking at. The diversity here is amazing and there is always something cool to find… whether it be a few dozen Sand Tiger Sharks cruising by or an Ocellated Frogfish or a bevy of juvenile Cubbyu… I am never disappointed.

What is your most memorable fish find and why? Possibly discovering a new species of fish is my most memorable fish find. Swimming along the sheer wall of Little Cayman at about 90 feet and looking into a little alcove and seeing a jawfish (blue spotted at that!). I couldn’t find the fish in any ID book, and so I contacted REEF for some help… It's still being worked on, but I am keeping my fingers crossed that it is a new species that I will get to name. Dottie’s Jawfish has a nice ring…don’t you think? I have had the chance to meet some incredible people in my diving career and the fishy ones are the best!
