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. It's impossible to list everyone here - please visit the Grouper Moon page to see the full list - http://www.REEF.org//groupermoonproject.

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.
Okay, well not exactly. But now that I have your attention. We ARE counting something in REEF HQ's backyard, not fish, but birds! I have signed myself /REEF up for Cornell University's Lab of Ornithology Project FeederWatch, an annual survey of birds that visit bakcyard feeders in winter. I have known about this other great citizen science program for a couple of years and like many of you, my love for birds, equals my affinity for fishes. Last week, 4 painted buntings visited REEF's feeder for a little over a week! You can see my fuzzy picture of a couple of them at the feeder from afar in one of the attached photos. This prompted me to go online and investigate Cornell University's FeederWatch Program further. From their homepage you will read, "FeederWatchers periodically count the highest numbers of each species they see at their feeders from November through early April. FeederWatch helps scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance." Sounds a bit familiar doesn't it?
Spend a little time on their website and you will see that FeederWatch parallels REEF programmatically in a few significant ways: 1. Anyone can participate in North America, all different levels from beginners to experts; 2. We both begin participation by purchasing a starter kit, FeederWatch calls theirs a Participant Kit and it costs $15; 3. Both organizations have online Dataentry and tracking of individual participant data; 4. Similar absence/presence data, abundances, and distribution for both groups in addition to viewing individuals' data http://watch.birds.cornell.edu/PFW/ExploreData; 5. Both of our organizations utilize citizen science data to inform and assist scientists in assessing population abundance indices of important avian and fish species, leading to peer-reviewed publications and ultimately influencing species and habitat management decistions; 6. You can check on their database to see what birds are rare in your area and if there are any other FeederWatch stations near you, just as REEF members can check for fish sighting frequencies and dive sites that have been surveyed in our areas of interest.
I'm sure there are many more parallels I could draw for you, but you get the point. One important note and the reason I am submitting this article right now is that FeederWatch season runs from the the second Saturday in November through April and is a winter activity. For all of our temperate REEF members who are looking for something to count when you're not underwater, this is it! To learn more, check out their website at http://www.birds.cornell.edu/pfw/Overview/over_index.html.
Greetings from REEF HQ! Conservation science is in sharp focus here at REEF, from an expanded Grouper Moon Project to new uses of REEF data in the Channel Islands.

It's one of the great things about fishwatching and doing REEF surveys - no matter how many surveys you have conducted, there is always an opportunity to find something new. These "mystery fish" are what keep folks who have done even 1,000+ surveys coming back for more. Finding a "lifer", a species new to your species life list, is always rewarding. A great part of submitting REEF surveys is that REEF keeps track of your lifelist for you.
One of the many data summary reports that are available through the REEF Website is your personal Life List Report, which includes all of the species that you have reported during REEF surveys. REEF Surveyors also have access to "My Survey Log", which lists information about each survey dive, including date, time, location and the number of species seen. In order to access these reports, you need to be logged into REEF.org. If you haven't already done so, create a Website login account today.
Active surveyors, Todd and Lynn Fulks, found one such "lifer" recently during a survey dive in San Blas, Panama -- a hogchoker (Trinectes maculatus). This little flatfish was happy to pose on Todd's slate underwater while they snapped a photo. Great find! Do you have your own great lifelist story? Please post it to the REEF Forum Discussion Board. And if you are looking for a great read this Fall, check out The Big Year: A Tale of Man, Nature, and Fowl Obsession by Mark Obmascik. It chronicles obsessed bird watchers participating in a contest known as the North American Big Year, hoping to be the one to spot the most bird species during the course of the year. If you are a fish fanatic, you will definitely see some similarities!
REEF's Grouper Moon Project Featured as "Success Story in Marine Conservation" REEF's research program focused on studying one of the last remaining large spawning aggregations of Nassau grouper in the Cayman Islands, the Grouper Moon Project, was included as one of 26 stories of good news in the typically grim news of marine conservation efforts. Dr. Brice Semmens, Grouper Moon Project lead scientist, presented results from the collaborative research efforts during the Beyond the Obituaries: Success Stories in Ocean Conservation symposium organized by Drs. Jeremy Jackson and Nancy Knowlton at the National Museum of Natural History last month. To watch Brice's talk archived online, click on this link and then navigate to about 52:45 on the time bar. The presentation is 10 minutes.
REEF Featured on NPR's Morning Edition REEF surveyor, Pacific NW diver, and NPR reporter Ann Dornfeld wrote and narrated a story that aired on National Public Radio on May 20th. The story covers a typical REEF survey, as well as discussing how the data is being used in Washington State to help understand the status of rockfish species.

The San Diego Oceans Foundation (SDOF) is one of REEF's valued partner organizations. SDOF has been supporting its volunteers to participate in REEF surveying for the last several years and has sponsored dozens of survey training workshops. SDOF recently honored REEF member, Bob Hillis, who is a long-time SDOF Reef Monitoring Volunteer, as their 2009 top volunteer for his invaluable support of the oceans. Having completed 202 REEF Surveys, Bob has continued to strengthen his connection to the sea while providing indispensable information about the status of marine populations off the coast of California. Bob joined REEF in 2006 and is a member of the REEF Pacific Advanced Assessment Team (AAT). In addition to being an active surveyor, he and his wife helped spread the REEF word last year at our SCUBA Show 2009 booth.
Bob says - “I started doing surveys when I saw a notice for an SDOF Fish ID class on the Divebums website. I had started fish watching a few years before when I reached the "been there, done that" point of diving in San Diego. I started diving here in the early '70's and did all the abalone, lobster, blue water spearfishing, divemaster, instructor, dive medtech and public safety diver things. I live in the mountains (about 60 miles from the coast), but the ocean is my favorite playground! I am also an avid surfer, body surfer and ocean swimmer. Doing REEF surveys with SDOF gives me an opportunity to enjoy my passions and give a little back to the ocean as well. These surveys actually force me to focus on and identify all of the species that I used to see (but not REALLY see). Always hoping to locate a new or rare species has added a new and exciting dimension to diving.”
Thanks for your efforts, Bob, and congratulations! And thanks to SDOF for their continued support of the REEF program.
Thirty miles offshore, in 100 feet of water, the Spike isn’t the most accessible dive site off North Florida’s coast but July 17th marked the first anniversary of the former Coast Guard tender’s deployment as an artificial reef so we were eager to see what had changed over the past year. The Spike had only been down 10 days when we surveyed it during last year’s Great Annual Fish Count. We weren’t expecting much then – the chance to dive a freshly minted reef was the main attraction, but it was interesting that it had already attracted a small crowd of nervous bottom fish, including the usual Black Sea Bass and Vermillion Snappers.
It was a very different site one year later. A large school of nosy barracudas followed the first diver down the line, clearing the way for hundreds of Atlantic Spadefish to move in and escort the rest of our group down. The Spike was surrounded by silversides that fled en masse as we moved through them, then streaked back to the structure for protection when gangs of Great Amberjack attacked. It’s difficult to describe the sound made by thousands of fleeing fish, but they are noisy. The superstructure is now covered with invertebrates – barnacles, tunicates, sponges, and anemones – that provide shelter and food for hundreds of tiny seaweed blennies. Jacksonville’s ubiquitous grunt, the Tomtate, was there in every phase from juvenile to adult. The Black Sea Bass and Vermillion snappers are now settled in under the bow with a group of small Red Snappers and waddling around in the sand was one of my favorites, a Polka-dot batfish! A year ago, I counted 6 species of fish. This year I counted 16 species.
Our group also dived the Gator Bowl Press Boxes, an artificial reef created years ago when the city’s stadium was renovated. Although it had about the same amount of biomass as the Spike, there were more species. One of the joys of offshore Jacksonville for fishwatchers is getting to see species like Dwarf Goatfish, Longspine Porgys, Bank Sea Bass and Oyster Toadfish that we see don’t tend to see in more tropical waters. Congratulations to Richard Salkin and T.C. Howe, who conducted their first REEF surveys.
