On July 17th, Maui celebrated its tenth year as part of the the Great Annual Fish Count (GAFC) with a great event at the Honolua Bay Marine Life Conservation District. As part of the event, several community groups combined to hold a REEF fish count, reef and shoreline clean-up, coral disease survey, and water quality testing. Long-time REEF partners, Donna Brown and Liz Foote, conducted a fish identification class at the Hawaiian Islands Humpback Whale National Marine Sanctuary the week before, and the Sanctuary furnished a van and organized a car pool to travel to the remote location. Trilogy Excursions donated a 64 foot sailing catamaran and crew to carry volunteers into the bay, and later invited the shore-based fish counters aboard for a free lunch. REEF surveyors saw and photographed over 70 fish species, including sea horses, oriental helmet gurnard, spotted eagle ray, and a cute baby frogfish. The GAFC is one of the monthly events hosted by the Maui-based Fish Identification Network (FIN). Visitors and new comers are welcome to attend monthly fish counts by contacting: Maui.FIN@gmail.com
Winter full moons mean that it's grouper spawning time! Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort with the Cayman Islands Department of the Environment (CIDOE) aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species. Our research focuses on Little Cayman, which has one of the largest (and one of just a few) known remaining aggregations of Nassau grouper in the Caribbean. We estimate that between 5,000 and 7,000 Nassau grouper come to the site to spawn. Thanks to funding from the Lenfest Ocean Program of the Pew Charitable Trusts, NOAA Coral Reef Conservation Program, and the Disney Wildlife Conservation Program, REEF and our partners at CIDOE and Oregon State University have used state-of-the-art technology, as well as good old fashioned diver surveys, and the research has yielded ground-breaking results. In 2003, the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all known aggregation sites in the Cayman Islands (both current and historic). This ban expires later this year and new legislation is being developed. We are rapidly compiling the results of our research, which will provide the Cayman Islands government guidance on how to best protect this important coral reef fish.
Earlier this month, we had a small team in the field- Dr. Selina Heppell (OSU researcher), Stephanie Archer (OSU graduate student), and Brenda Hitt (long-time REEF Grouper Moon volunteer). They witnessed spawning on two nights following the January full moon. We expect February to be the "main" spawning month (based on past research, we know it has to do with when the full moon is in relation to the winter solstice). A much larger team of researchers and volunteers will be on the island to conduct a full suite of research projects. We will also be producing several outreach products aimed at promoting the management and conservation of these spawning aggregations. Stay tuned for more information on this exciting and important marine conservation research. In the mean time, to find out more, visit the Grouper Moon Project Webpage. To see video of the aggregation during the day, check out this video on YouTube taken last year. If you would like to support this critical marine conservation research, please donate today through the REEF Website or call REEF HQ at 305-852-0030.
During our Summer Fundraising Campaign, we reach out to you, our valued members, and ask for your financial support.

REEF Director of Special Projects, Lad Akins, has co-authored several recent scientific publications on the invasive lionfish in the western Atlantic, including:
-Diet richness of invasive Indo-Pacific lionfish revealed by DNA barcoding. Marine Ecology Progress Series. Significant research by REEF researchers and others has been conducted looking at stomach contents of lionfish to identify prey. However, relatively few prey species have been identified because of the challenge of identifying partly digested prey. The authors of this study addressed this issue by DNA-barcoding unidentifiable fish items from the stomachs of 130 lionfish. They identified 37 prey species, half of which had previously not been recorded as lionfish prey.
-Rapid invasion of Indo-Pacific lionfishes (Pterois volitans and Pterois miles) in the Florida Keys, USA: evidence from multiple pre- and post-invasion data sets. Bulletin of Marine Science. This paper uses data from the 20,000+ REEF surveys conducted in Florida since the early 1990s, along with other long-term data sources, to document the appearance and rapid spread of lionfishes in the Florida Keys. Between 2009 and 2011, lionfish frequency of occurrence, abundance, and biomass increased rapidly, increasing three- to six-fold between 2010 and 2011 alone.
- Habitat complexity and fish size affect the detection of Indo-Pacific lionfish on invaded coral reefs. Coral Reefs. This paper explores detectability rates of lionfish using underwater visual census methods such as belt transects and stationary visual census. Knowing the error in these methods specficially for lionfish is necessary to help study this invasive species in the western Atlantic. The authors found that the two census methods detect fewer than 30% of lionfish present in an area and, in more than 50% of the cases, fail to detect any lionfish when one or more indivudals are actually present.

REEF's Director of Special Projects, Lad Akins, and REEF affiliate scientist Dr. Stephanie Green (Oregon State University) and REEF Advisory Panel member Dr. Steve Gittings (NOAA National Marine Sanctuaries) participated in the first submersible expedition to assess the lionfish invasion on deep marine habitats off South Florida June 27-29. While REEF and other scientists have studied lionfish in shallow habitats, the Antipodes lionfish expedition gave scientists the opportunity to learn about lionfish populations far below recreational diving limits. The five person submersible is capable of descending to 300 m (1,000 ft) deep and has large acrylic domes that allow for observations and photography.
During the expedition, team members including Dr. Gittings and Dr. Green completed dives to 300ft in the submersible to look for lionfish on both natural rocky and artificial reefs, including the 209ft-long cargo ship Bill Boyd. Both scientists sighted dozens of invasive lionfish in all habitat types during the dive, highlighted by view of the stern of the wreck holding dozens of lionfish. Dr. Green also conducted a number of REEF surveys to document the native fish community in areas invaded by lionfish, sighting a number of reef fishes that are often only found below recreational dive limits, including snowy grouper, roughtongue bass, red barbier, short bigeye, and bank butterflyfish.
The project, hosted by NOVA Southeastern University, was led by OceanGate Inc. and included participants from Florida Fish and Wildlife Conservation Commission, University of Miami, NOVA, and Guy Harvey Foundation, and others. On Saturday following the expedition dives, Lad Akins, Dr. Green, and Dr. Gittings met with media and the public in a half-day summit to discuss the invasion and potential actions to manage lionfish populations in areas that can't regularly be accessed by divers. The summit concluded with a lionfish filleting demonstration by Lad, and a tasting of lionfish ceviche prepared by Kareem Anguin, Executive Chef, The Oceanaire Seafood Room. See the expedition website for more information.
As part of a Florida Sea Grant funded project, REEF is working this summer to assess deepwater lionfish populations in the Florida Keys using ROVs and technical divers.

The 22nd annual Great Annual Fish Count (GAFC) is rapidly approaching! Will you be participating? We encourage local shops, dive clubs, and other groups to organize an activity anytime during the month of July (and often training events in June). You can view events already scheduled, and add your own, by visiting www.fishcount.org.
The concept behind the GAFC is to not only accumulate large numbers of surveys during the month of July, but to introduce divers and snorkelers to Fishwatching and conducting REEF surveys. Interested groups can offer free fish ID classes, organize dive/snorkel days, and turn them into fun gatherings! To find out more, contact us at email@example.com.
A recent publication in the scientific journal, Conservation Letters, examined the invasion of lionfish in to the western Atlantic and Gulf of Mexico waters. The authors compared traditional reef fish monitoring efforts to less traditional data including the observations of divers through REEF's Volunteer Fish Survey Project and spearfishers. They found that citizen observations documented lionfish 1-2 years earlier and more frequently than the more traditional monitoring efforts. The authors also explored the willingness of spearfishers to help minimize impacts of the invasion by harvesting lionfish. They found that spearfishers who had encountered more lionfish while diving perceived them as more harmful to the habitat than less experienced divers and were also more likely to participate in harvesting initiatives. The authors also report that encouragement from scientists and managers was a far better motivator than the desire to harvest lionfish for personal consumption. This study demonstrates the value of engaging citizens for assessing and responding to large-scale and time-sensitive conservation problems.
