REEF members are at the heart of our grassroots marine conservation programs. Over 60,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Adam Nardelli. Adam has been a REEF member since 2009, and he served as a REEF Intern in 2014. He has conducted 54 surveys and has participated in several of REEF's programs. Here’s what Adam had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I first learned about REEF as a PADI dive master when I became involved in doing group fish surveys and held a Great Annual Fish Count event at a local dive shop in Fort Lauderdale, FL. I eventually became a PADI instructor and started teaching my own fish identification courses for many of the local dive shops. In 2009, the spread of invasive lionfish started to reach the shores of south Florida, and as a dive professional and passionate steward of the local reefs, I quickly saw this issue as an important threat that needed to be understood and treated for management. I started a research project on the lionfish invasion while I studied a graduate program at Nova Southeastern University Oceanographic Center, and partnered with REEF and Lad Akins as a REEF Intern.
If you have been on a REEF Field Survey, where and what was your trip highlight?
My involvement with REEF has influenced most of my diving career well into shaping my view as a marine conservation steward and professional educator today. As a REEF Intern, I was fortunate to assist with several field surveys, and I would have to say that among all of them the single highlight was the ability to dive and learn from the staff members. Of course, my most memorable surveys were conducting lionfish transects with Lad, Stephanie, and the other REEF volunteers. There were as many long, cold, wet days as there were warm, sunny ones where we spent hours in the water surveying many of the diverse reef habitats around the Florida Keys. There were so many dive stories that we came away with, but I would have to say the most memorable was when we were approached by a huge sailfish chasing bait.
I also had the extraordinary experience of assisting with the Grouper Moon project in Little Cayman with Christy Pattengill-Semmens and Brice Semmens. This was an opportunity to help conduct research and promote continued protection for the endangered Nassau Grouper. It was an honor to learn from the sharp set of fish identification skills that Christy and Brice possess as expert field researchers. Swimming with large schools of these charismatic fish was a memorable dive adventure.
Lastly, just this past summer in 2015, I participated in the Roatan Field Survey group, which was led by Anna and Ned DeLoach. It was wonderful to dive with these two fish “aficionados” as we explored every coral crevice and sand hole in search of rare, cryptic and elusive creatures. It’s hard not to have fun with them around, as diving with these two really makes one appreciate how remarkable life under the ocean can be.
What inspires you to complete REEF surveys?
I am inspired to continue to do REEF surveys because it adds value to every dive I make. Not only am I contributing data for scientific endeavor, but it also enables me to appreciate the reef in a very real, detailed way. During each dive, I can account for every creature that I observe and take the time to watch their behavior. Diving becomes more like a visit with a friend than just being a passerby.
What is the most fascinating fish encounter you’ve experienced?
There are so many diverse and fascinating fish in the oceans that it would be hard to choose just one to top the list. However, during my most recent dives in Cozumel this year I encountered a perfectly cryptic Longlure Frogfish. When the dive master pointed to the coral head, I thought critically, “this guy thinks I’ve never seen a sponge before.” But then upon closer visual inspection, the pectoral fins and eyes began to take shape. With greater concealment than any octopus or scorpionfish I have encountered, this creature is truly unique.
Do you have any surveying, fishwatching, or identification tips for REEF members?
My best tip for fishwatching and being a good surveyor is to slow down and take your time to dive. Be still in the water and watch the fish school around you. Practice good buoyancy control as well. You will not only appreciate the reef more, but the fish will respond better towards your presence and allow you the close inspection you may need to get that positive key identification feature.
We are excited to share with you a once-in-a-lifetime opportunity to join REEF on a special expedition next spring. In partnershp with Florida International Univeristy (FIU), we have arranged for a small team of REEF members to experience another level of ocean exploration. Our team will venture beneath the waves and spend a night in the FIU Aquarius Reef Base, the world’s only undersea research laboratory. Deployed 60 feet beneath the surface in the Florida Keys National Marine Sanctuary, the Aquarius Reef Base is the world’s only undersea research station and is used to study the ocean, test and develop undersea technology, and train astronauts. Less than 1,500 people have ever ventured inside Reef Aquarius Base, and even fewer have spent the night in the underwater habitat.
The project dates are March 5 - 10, 2017, and includes 4 nights of lodging in Marriott Bayside Resort in Key Largo, 3 days of 2-tank dives with Quiescence Diving Services, a night spent in the Aquarius Reef Base, and classroom sessions with REEF and Aquarius staff each day. Note that the time spent in the Aquarius is not a saturation dive. The pressure inside Aquarius will be adjusted during the overnight stay, and participants will not be allowed to venture outside of the Habitat until departure from the Habitat. Cost to participate is $4,500. If you are interested in finding out more, visit the Aquarius Expedition website.

Dollars to Help Develop Rapid Response Plan
In April of this year, REEF received notice our proposal to develop a Marine Exotic Species Action Plan was partially funded through the Mote Marine Protect Our Reefs Fund, which is funded through the Florida coral reef license plate. The project funding will go towards a SE Florida workshop with key federal, state and local agencies to develop a coordinated response plan for dealing with non-native marine fish. To date there have been more than 20 species of non-native fishes documented in a four-county area in Southeast Florida. Of these, the indo-pacific lionfish has become established in the US and Bahamas and is rapidly spreading throughout the Caribbean. To help address this issue and prevent other non-native fish invasions, coordinated early detection and notification, and rapid response plans are needed.
REEF will be working in partnership with the USGS and NOAA to lead the early summer workshop focusing on drafting these coordinated action plans. Funding for outreach and to establish and train response teams later this summer is still being sought as part of this effort.
Stay tuned for an update on the workshop and for future plans for development of local response teams. Be sure to report any sightings of non-native marine organisms to the REEF exotic species website at www.reef.org/programs/exotic
The M/V Wellwood, a 122-meter freighter, ran aground in 1984 on Molasses Reef off Key Largo, Florida. The grounding destroyed 1,285 square meters of living corals. The grounding transformed the area into a flattened, barren pavement covered with coral rubble. Eighteen years after the grounding, the area resembled nearby hard ground habitat with little structure and the benthic community was dominated by gorgonians. Natural recovery to a state similar to the pre-grounding condition failed to occur within a reasonable time frame and therefore, habitat restoration was initiated in May 2002. In the Fall of 2007, REEF completed a five-year monitoring project on the fish assemblages at the Wellwood grounding site and two nearby reference areas. A Summary Report, which summarizes the results of the monitoring effort, has been completed and is available for download from the REEF Wellwood Monitoring webpage.
Baseline surveys were conducted just prior to and immediately following restoration, quarterly monitoring took place through Year 1 and semi-annual monitoring in Years 2 through 5. The primary goals of this project were to aid in the assessment of restoration efforts and provide a benchmark for long-term evaluation of the fish communities at the grounding site. Teams of REEF Advanced Assessment Team divers conducted 558 roving fish surveys and 559 belt transect surveys during the five year monitoring project.
After initial colonization, Restoration site fish assemblage diversity, density and biomass have leveled off and remain lower than that at nearby reference areas. A total of 165 fish species were recorded at the Restoration Site during the 5-year project. In comparison, 189 were documented at the North Reference site and 207 were documented at the South Reference Site. Parrotfish and surgeonfish appear to be responding quickest to the restoration efforts, with densities and biomass values similar to that of the reference sites. Grunt and snapper species are primarily absent from the Restoration Site. The relatively short duration of this study makes it difficult for results to be teased out from natural population variability. Similarly, definitive conclusions cannot be achieved from these data due to the limited amount of time that has passed since restoration and the well-known decadal processes that are required for coral reef development. However, these data will serve as a critical baseline for assessing future changes and the effect of any future restoration efforts at the site.
For more information about the 5-year project and to read the full report, visit the REEF Wellwood Monitoring webpage. There was also a longer story about the project in the January 2008 REEF-in-Brief.
Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort in the Cayman Islands aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species. The 2009 spawning season was the most ambitious to date for the project. For the first time, we had teams of researchers and volunteers stationed on each of the three Cayman Islands--Grand Cayman, Cayman Brac, and Little Cayman. The field season was certainly a success; among many interesting results and accomplishments, our most exciting find was that the teams on all three islands witnessed Nassau grouper spawning on the same night (Valentine’s Day, of all days! – which happened to be 5 nights after the full moon).
In 2003 the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all historically known aggregation sites in the Cayman Islands. This followed the discovery by fisherman of 7,000 aggregating Nassau grouper on the west end of Little Cayman in 2001 and the subsequent harvest of 4,000 of those fish over two spawning seasons. At the time, all other known Nassau grouper aggregations in the Cayman Islands had become inactive due to over-harvest. Thanks to a three-year grant awarded in 2008 by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF is conducting research through the Grouper Moon Project to evaluate the current status of the Cayman Islands spawning aggregations and the effect of these harvest protections -- “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”.
The broad goals for the 2009 spawning season were to continue monitoring recovery in the large spawning aggregation on Little Cayman, and to expand research into the fate of remnant spawning aggregations on Cayman Brac and Grand Cayman; aggregations on both of these islands were fished to exhaustion in the recent past. In addition to the island specific objectives, the Grouper Moon research program expanded satellite drifter work this season. These drifters, which track current patterns associated with the body of water the grouper eggs were spawned in, will continue to report positions for 45 days after spawning; this length of time is the approximate larval duration for Nassau grouper. REEF also continued education and outreach efforts through public talks about spawning aggregations and the Grouper Moon research. Talks were held at the Little Cayman National Trust and Dive Tech/Cobalt Coast Resort.
2009 Aggregation Season Results Summary
The Little Cayman team continued the long-term monitoring of this aggregation, which includes counting the number of fish that show up, estimating the size of the fish, and recording the timing and amount of spawning observed. The Cayman Brac team’s goal was to document whether or not aggregating Nassau grouper were spawning-- evidence of spawning would refute the theory that Nassau grouper fail to recover once overfished because fish on small aggregations no longer release gametes. In the 2008 spawning season, the Grouper Moon research team discovered the location of an aggregation of Nassau grouper on Cayman Brac. This year, armed with this information, REEF and CIDOE researchers spent the full 2009 spawning season observing, videoing and documenting the Cayman Brac spawning aggregation. In addition, the team was able to accomplish the primary goal of this season’s work on the island—team members both observed and videoed spawning. Objectives for the Grand Cayman team were similar, except that they first had the task of discovering where Nassau grouper on that island go (if anywhere) during the spawning season. Using the acoutic tag pinger signal of just ONE Nassau grouper (of 6 total individuals tagged on Grand Cayman in 2008), divers confirmed the presence of aggregating grouper near the historic East End aggregation site and a dusk dive on February 14th yielded this season’s biggest accomplishment– team members witnessed Nassau grouper spawning on Grand Cayman!
The findings stemming from this work are unquestionably novel, and are certainly good news —protections on aggregation sites that have been fished to exhaustion will protect those few individuals that remain, and will protect stocks of fishes that are contributing to the next generation of this endangered reef fish. Put simply, our research demonstrates that overfished aggregations are down, but not out.
Why Does This Matter?
Nassau grouper are not just icons of the Caribbean; they are a social and ecological cornerstone of the region’s coral reefs. Historically, Nassau grouper represented one of the region’s most economically important fisheries. Unfortunately, due to intense harvest on spawning aggregations, their populations have dwindled to a fraction of their historic numbers. The species became the first Caribbean reef fish to be listed as endangered by the International Union for the Conservation of Nature (IUCN) and the species is candidate listed under the US Endangered Species Act. The precipitous decline in mass spawning aggregations of Caribbean grouper species has been well documented. The majority of known Caribbean aggregation sites are now inactive due to the ease with which aggregating species are caught. And those that are still active contain significantly fewer fish than the 10s of thousands that historically gathered at these special places.
As part of our work on the Grouper Moon Project, REEF will continue to develop a comprehensive assessment of the status of the Cayman Island’s Nassau grouper spawning population as a guide for future Nassau grouper restoration and conservation policy.
Collaborators and Supporters Who Make This Project Possible
REEF would like to thank our collaborators at the Cayman Islands Department of the Environment, specifically Phil Bush, Bradley Johnson, Croy McCoy, James Gibb, Tim Austin, Gina Ebanks-Pietre, Chris Dixon, Keith Neale, Delwin McLaughlin and Robert Walton, as well as Drs. Scott and Selina Heppell from Oregon State University. REEF Volunteers have always been at the core of our Grouper Moon field work and 2009 was no exception – heartfelt thanks to Judie Clee, Thor Dunmire, Tracey Griffin, Doug Harder, Brenda Hitt, Denise Mizell and Sheryl Shea. The Grouper Moon Project has continued through the years empowered by the first year’s success and the passion of early project leader Leslie Whaylen Clift. Assistance from OSU graduate students, Stephanie Kraft and Heather Reiff, is much appreciated. Principal financial support is from the Lenfest Ocean Program of the Pew Charitable Trusts and the CIDOE. Additional funding is from Mr. Wayne Panton, Mr. Dan Scott, Clive and Stella Wood, Franklin and Cassandra Neal, and hundreds of REEF members. Continued in-kind logistical support from island businesses and residents, including the Little Cayman Beach Resort/Reef Divers, the Southern Cross Club and Peter Hillenbrand, is also much appreciated. And finally, our ground-breaking achievements on Cayman Brac would not have been possible without the generous support of Wayne Sullivan, who donated his vessel the Glen Ellen, his time (and patience), his equipment and technical diving expertise, and his crew, Brady Booton and Jules James.

Planning is underway for REEF's annual research on Nassau grouper spawning aggregations in the Cayman Islands for the 2010 spawning season - the Grouper Moon Project. This collaborative conservation program between REEF and the Cayman Islands Department of the Environment is entering its 8th year. Thanks to funding from the Lenfest Ocean Program of the Pew Charitable Trusts, the research team is conducting innovative research that is critical to the long-term survival of this iconic Caribbean species. Grouper Moon scientists will be in the field January 30 - February 12, 2010. If you are looking for a winter getaway and are considering the Cayman Islands, this is a great time to visit Little Cayman.
While there are not opportunities for recreational divers to visit the aggregation, researchers will be giving several public talks and divers on Bloody Bay Wall will witness the mass migrations of the normally solitary Nassau grouper from their home reefs out to the aggregation site. Another good reason -- the acclaimed Southern Cross Club has offered to donate a percentage of any package booked by REEF members during that time to support REEF's Grouper Moon Project. To take a vacation and make a positive impact for the grouper, contact the Southern Cross Club reservation office directly at 1-800-899-2582 or info@SouthernCrossClub.com -- be sure to mention that you are a REEF member!
More information about the 2010 research and program objectives for the Grouper Moon Project will be included in future issues of REEF-in-Brief. you can also find out more about the Project on the Grouper Moon Project Webpage.

REEF Field Surveys offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. The recent trip to Key Largo was no exception. REEF surveyors gathered in late August at Amoray Dive Resort for the Key Largo Field Survey and Coral Conservation trip. The trip was scheduled around the annual coral spawning that usually occurs in the Keys after the full moon of August. Amy Slate, owner of Amoray, organized a great week of activities, including presentations by Lauri MacLaughlin, from the Florida Keys National Marine Sanctuary (FKNMS) and Ken Nedimyer, founder of the Coral Restoration Foundation. A 3-minute highlite video is posted on YouTube here.
Ned DeLoach kicked off the week with presentations about fish behavior and an overview of Key Largo’s more famous fish species. Key Largo is known for its grunts so we started the week with back-to-back dives on the Benwood, where fish watchers can regularly observe eight species of grunts on a dive. The second dive was timed with the daily arrival of the parrotfish that bed down for the night in the nooks and crannies of the wreck. Hundreds of Blue, Midnight and Rainbow parrotfish arrive around sunset and spend about 15 minutes swooping around before they settle in to sleep. For veteran fish counters, this is a bonanza because it is extremely rare to be able to mark Abundant (over 100) for Midnight parrotfish!
Lauri MacLaughlin has amassed an extensive collection of spawning coral video and uses it to educate the public about the plight of coral reefs but also showcases Sanctuary programs that give hope for their future. After her presentation, our group joined Lauri and her team on the projected night for spawning staghorn and elkhorn coral. They placed tents over selected corals to capture gametes for research while we spent several hours watching for signs of gamete bundle formation in the polyps. Unfortunately none of the research groups stationed all over the Keys observed any spawning that evening.
To continue with our coral conservation theme, Ken Nedimyer joined us to tell us his inspiring story about how he made the transition from live rock farmer for the aquarium industry to coral farmer. Ken and his family turned a few small coral recruits that settled on his live rock into over 5,000 growing coral colonies. His organization has now successfully transplanted corals on a number of reefs in the Florida Keys Sanctuary. After Ken’s talk we load up the boat for a visit to his coral nursery and some hands-on work. There is no better way to understand the scope of what he has accomplished than to see it for ourselves and contribute to the cause by helping with some of busy work scrubbing algae and cementing coral fragments to concrete bases. Fish surveys in the coral nursery are usually productive and this time included a tiny jackknife fish and an Emerald parrotfish.
The week included a visit to REEF headquarters where staff and volunteers, Jane Bixby, Karla Hightshoe and Nancy Perez treated us to refreshments and a tour. Field Operations Coordinator Alecia Adamson gave her very informative presentation about REEF’s programs dealing with the invasive lionfish in the Tropical Western Atlantic.
Other highlights of the week included a dive with a very inquisitive Goliath grouper and a rare chance to survey the grass beds and mangroves on the Florida Bay side of Key Largo, where we added Sea Bream, Inshore lizardfish, and Banner and Frillfin gobies to our list. We ended the week with two dives at Snapper Ledge; a site that has received a lot of attention in the past few years by groups who are petitioning to have the area designated a Sanctuary Preservation Area to protect the thousands of fish that gather there. It was a fishwatcher’s dream, a fitting way to end the week.
If all of this sounds fun, we hope you will join us on a future Field Survey. The 2011 trip schedule is now posted online here -- http://www.reef.org/fieldsurveys/schedule
