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.

This year, we also have gifts to give in appreciation of your donation, which include a print of a limited edition, signed print of Sailfin Blenny ($250 or more), acknowledgement on the Giving REEF ($500 or more), and a special webinar with Ned and Anna DeLoach ($1,000 or more).
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. Visit www.REEF.org/db/publications to see this and all of the scientific publications that have included REEF Volunteer Fish Survey Project data.
Here's what we're up to in the coming months:

Once again, CEDAM International is offering two scholarships for educators to participate on a REEF Field Survey. For the 2008 survey season, the scholarships will apply to the Gran Bahia Principe Field Survey in Akumal, Mexico. Dates for this trip are May 17-24, 2008. You can visit REEF's Field Survey page to view trip details and also check out the trip flyer. To apply for this scholarship, please visit the CEDAM website at then click on the Lloyd Bridges Scholarship tab at the top of the page to see details.
The two scholarships enable qualified educators to participate - at no cost - in a CEDAM-sponsored or -sanctioned expedition. This REEF Field Survey will be led by Joe Cavanaugh, REEF Field Operations Director. Participants will have the opportunity to collect data, participate in daily talks, and interact with REEF members, staff, and local organizations. This will be a hands-on experience during which participants have the opportunity for fish identification and marine conservation training in and out of the water. REEF has partnered with ReefAid and Reefcheck and Ecologica Bahia in 2007 to assist Gran Bahia Principe Resort with developing a monitoring and assessment protection plan for their nearshore reefs. Our cooperative efforts in conservation at Bahia Principe are making a difference in protecting their reefs and some of our class time will focus on these successes.
To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization.The scholarship will be awarded on the basis of both merit and financial need. CEDAM International will cover the recipient’s airfare and REEF Field Survey expenses (excluding incidentals and personal expenses), on this educational adventure. Bahia Principe is an all-inclusive resort so acoomodation, diving, and meals are included. The application deadline will be earlier than last year's deadline since the Field Survey pariticipation dates are in late May this year. Please have your completed applications submitted by April 1, 2008.
Many of our members may be too young to have seen the television program, Sea Hunt, starring Lloyd Bridges that ran from 1958-1961. One important aspect of the series was that Bridges made a plea at the end of each episode to protect the oceans, an early ocean conservation pioneer. He was also involved in several organizations including the American Oceans Campaign and Heal the Bay, a Los Angeles-based conservation group. He inspired a generation of SCUBA divers and you may want to check out Wikipedia to read more about many of the people Bridges worked with on Sea Hunt. Incidentally, I discovered that Bridges learned to SCUBA dive once contracted for the show and that he was offered the role of Captain Kirk before William Shatner!
There are still spaces (4) available for the Akumal Field Survey, email firstname.lastname@example.org to inquire.
All applicants must complete an application form and return it along with the required essay and two letters of recommendation, to CEDAM (by mail or electronically) by April 1, 2008. Good Luck!
As many of you are aware, the recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the USGS, the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem.
Our most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement. To wit:
To date, dive operators and the contributions of participating volunteers have funded the bulk of this work. REEF’s future field-work will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program. For additional information, please contact Lad Akins at (305) 852-0030 x-2# or e-mail Lad@reef.org
As Fall is upon us, we look ahead to 2009 and a great lineup of REEF travel opportunities. Our partners at Caradonna Dive Adventure have helped us put together an exciting Field Survey schedule, including St. Croix, Bermuda (with Ned and Anna DeLoach), and Grenada on the Peter Hughes Winddancer (with Paul Humann). These week-long projects are led by experts in fish identification and include great diving, learning, and camaraderie with like-minded divers and snorkelers. Your non-diving companions are welcome on all of the land-based projects. There will also be several Lionfish Research Project expeditions, which allow participants to get first hand experience in this exploding invasive species issue. Be sure to check out all of these trips, posted online at http://www.reef.org/fieldsurveys/schedule. And remember that it's not just on REEF Trips that you can Make Dives That Count! You are encouraged to conduct surveys during your personal dive vacations farther afield and on local weekend dives in your own backyard. Be sure to order survey materials through the REEF Online Store before you leave and check out what species you are likely to see with the Geographic Summary Reports. And while you are waiting for your tank to be filled, it's fun to tell the folks at the dive shop what you are doing. Being a REEF ambassador helps spread the word about the Volunteer Survey Project and the value that fishwatching adds to your experience in the water. We hope that you will join us in making dives that count in 2009. We are kicking off the year with a Field Survey to St. Lucia led by new REEF Executive Director, Lisa Mitchell. To find out more or to book your space, please contact our dedicated travel specialist at 877-295-7333 (REEF), REEF@caradonna.com. And be sure to download our 2009 Trip Flyer!
