Divers will return to Florida Keys waters next month on a mission: net thousands of dollars in cash and prizes while protecting the environment from invasive lionfish. REEF and the Florida Keys National Marine Sanctuary are hosting the second annual lionfish derby series starting May 14, in Long Key, Fla. In 2010, the inaugural series of lionfish derbies removed 664 of the Pacific invaders from sanctuary waters. “Anyone who appreciates the diversity of the Keys coral reef should be concerned about these invasive fish,” said Sean Morton, Sanctuary Superintendent. “Divers have been actively engaged in lionfish removal in the Keys since 2009 and these tournaments are a way to reward them for their dedication to the reef.” Researchers will collect samples from lionfish caught at the derbies to learn more about lionfish genetics, growth, and impacts to native marine life. Each tournament also includes a detailed awareness and training briefing and lionfish tasting. In addition to the derby on May 14, two other events will be held later this year -- August 20 at Coconuts Restaurant in Key Largo and November 5 at Hurricane Hole Marina in Key West. To find out more about the Derby Series, visit the Derby Webpage.
Divers and snorkelers removed 1,518 invasive lionfish from Florida Keys waters during three Lionfish Derby events in 2011. Organized by REEF in partnership with the Florida Keys National Marine Sanctuary, the Florida Keys Lionfish Derby series began in 2010 to engage local communities in addressing the invasive lionfish issue. Goals of the lionfish derby series include raising awareness, educating collectors in safe collecting and handling procedures, providing samples for research, conducting lionfish cooking demonstrations and tastings for the general public, and encouraging ongoing removal efforts throughout the region. Teams of registered divers competed for cash and prizes in the categories of most, largest, and smallest lionfish. Dive teams traveled from as far as Chicago, IL.; Austin, TX; and Sunapee, NH to compete in the derbies. Participants and attendees observed filleting demonstrations and enjoyed tastings of lionfish caught during the event. Researchers from the U.S. Geological Survey, Salisbury University, University of Florida, Loyola University, international researchers from the UK, the State of Florida, and NOAA all utilized samples and data from the derbies to aid in their lionfish research. Growing populations of lionfish off the southeast U.S., Caribbean, and Gulf of Mexico are impacting native marine life commercially, recreationally, and ecologically important species. Derbies are just one of several strategies being employed to help control the lionfish invasion.

Climate change is expected to cause a poleward shift of many temperate species, however, a better understanding of how temperature and species' life histories interact to produce observed adult range is often lacking. REEF data were featured in a new publication on this topic in the scientific publication, Journal of Experimental Marine Biology and Ecology. The publication's authors evaluated the hypothesis that juvenile thermal tolerance determines northern range in gray snapper (Lutjanus griseus), a species commonly caught as juveniles along the US Atlantic coast well north of their adult distribution, using a combined laboratory, field, and modeling approach. To evaluate the relationship between juvenile thermal tolerance criteria and adult distributions, the authors used the REEF database to quantify adult distribution. There was a strong correspondence between observations of adult gray snapper from the REEF database vs. latitude of the predicted survival of juveniles vs. latitude from their modeling analysis. The agreement between the laboratory-derived thermal tolerance measures, the spatial distribution of winter temperature, and the distribution of adult gray snapper support the hypothesis that the adult range of gray snapper is largely limited by the overwinter survival of juveniles. The authors stated that "understanding the interaction between physiology and range is important for forecasting the impacts of climate change on other species of fish where juvenile tolerances are critical in determining range, particularly in seasonal systems". The abstract of the paper and supporting figures can be viewed online here. Visit the REEF Publications page to see all of the scientific publications that have featured REEF data.
On December 3rd and 5th, REEF and the Cayman Islands Department of the Environment (DOE) held free educator workshops on Grand Cayman and Cayman Brac in the Cayman Islands. The professional development workshops presented the Grouper Education Program, a marine sciences curriculum for intermediate/elementary and high school students that was developed as part of the Grouper Moon Project. Nineteen teachers from 12 schools participated, including 2 schools from the Bahamas. Participants received the materials and resources necessary for successfully implementing the Grouper Education Program in their classrooms. This exciting project focuses on bringing the Nassau Grouper into classrooms through lesson plans and interactive live-feed video sessions that connect classrooms with Grouper Moon scientists in the field.
The curriculum presents a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important fish. Key curricular concepts include the historical role of the species as an artisanal fishery throughout the Caribbean region, the grouper’s value as a keystone predator and its impact on local reef health, its role in today’s tourism-based economy in the Cayman Islands and throughout the Caribbean, and the conservation challenges facing Nassau Grouper given steep declines in populations. In addition to classroom lessons, the program includes live-feed video sessions that take place at the Grouper Moon Project research site on Little Cayman, bringing real-world field science into the classroom.
The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support for the workshops was provided by Cayman Airways, Brac Reef Beach Resort, and LIME. The program curriculum was developed to complement the research and scientific efforts of the Grouper Moon Project. Grouper Moon educator, Todd Bohannon, along with Grouper Moon scientists Brice Semmens, Ph.D. (Scripps Institution of Oceanography), Christy Pattengill-Semmens, Ph.D. (REEF), and Mr. Bradley Johnson (DOE), have led the educational effort. Activities were developed in consultation with teachers at Cayman Prep on Grand Cayman, Verity Redrup and Brenda Bryce, and Cynthia Shaw, author of the youth fictional book, Grouper Moon.

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 research group at Palm Beach State College is using REEF data on South Florida fish assemblages to evaluate beach renourishment projects.
- Researchers from NOAA's Biogeography office are including REEF data in the development of a management plan for the marine portion of the NE Ecological Corridor Reserves in NE Puerto Rico and Culebra Island.
- Researchers at Bimini Biological Field Station are using REEF sightings of two endangered sawfish species to better understand the species' current distribution and status.
A complete list of scientific publications featuring REEF programs and data can be found at www.REEF.org/db/publications.
Scientists and volunteers from REEF, and our partners at Scripps Institution of Oceanography and Cayman Islands Department of the Environment, are gearing up for the annual Grouper Moon Project next month. Scientists will be on the ground and in the water during the full moon in January. Since 2002, the group has conducted ground-breaking research to study the Nassau Grouper spawning aggregations, to help ensure recovery of the populations of this iconic species. This year, the team will be collaborating on new work using cutting-edge technology including underwater microscopes to evaluate larvae in-situ. We will also be hosting several live-feed videos through Google Hangouts as part of REEF’s Grouper Education Program. In 2011, with funding from Disney Conservation Fund, REEF launched the education program to engage Caymanian students in the project. This exciting initiative brings the Nassau Grouper into elementary and high school classrooms through lesson plans and the Hangouts that connect classrooms with scientists in the field. We will post Hangout details on our Facebook page and www.REEF.org/groupermoonproject in a few weeks.
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.
Six volunteer divers from the REEF Advanced Assessment Team (AAT) surveyed two sites off the Aquarius Reef Base in Key Largo, Florida, to assist the National Marine Sanctuaries Program (NMSP) with the science component of the Aquarius 2007 Mission: If Reefs Could Talk. Aquarius, the world's only undersea laboratory, is part of NOAA's National Undersea Research Program (NURP) and sits seven miles off shore at Conch Reef. A valuable resource and good neighbor to REEF HQ, Aquarius hosts scientists from around the world, from sponge chemists to astronauts, in innovative research and education.
The team included REEF Special Projects Manager Lad Akins and AAT members Dave Grenda, Brian Hufford, Lillian Kenney, Wayne Manning, and Mike Phelan. Twelve fish surveys were conducted at each of two research sites near Aquarius using the Roving Diver Technique (RDT). This year's data will be compared to surveys collected during a 2001 mission to assess change in resident fish populations. The team also assisted NMSP in documenting the occurrence of long-spined sea urchin (Diadema) at each site. Once abundant on Florida Keys coral reefs, herbivorous Diadema play an important role in keeping coral-stifling algae from overtaking the reef structure.
