Needed -- a few more volunteers for this critical marine conservation project in Belize! Peter Hughes and REEF’s Lad Akins will lead this great project aboard the livaboard dive vessel Sun Dancer II, June 13-20. I am sure that most of you have been following the news about the lionfish invasion and the recent updates on fish beginning to show up in Belize. We are really concerned about this. The Central American coast is going to be the most likely pathway for introduction of the fish into the Gulf of Mexico and the extremely valuable fish and shrimp industry there.
What can we do? One of the first things that can be done is early detection and rapid response to remove these fish as they show up. To that end Peter Hughes Diving has worked with REEF to organize the first lionfish assessment and removal project in Belize (or anywhere in Central America for that matter!). This is going to be a great first effort on detecting fish, removing what we see and training local staff on how to collect and handle the fish so they can remove them year-round.
What do we need? We need more of you! We need your interest, expertise and involvement to make this project a success. We know that times are tight and there is concern over travel to some areas, but this project is not to be missed. We will be offshore on the Sun Dancer II, one of the most highly regarded liveaboards in the region. First class service, first class diving and a very important mission!
We hope you can make this project! For more information and to sign up, call Peter Hughes Diving at 1-800 9 DANCER (800-932-6237). You can also contact REEF Director of Special Projects, Lad Akins, with any of your lionfish questions and to find out more about this trip (firstname.lastname@example.org, 305-852-0030).
We look forward to seeing you there!
Active REEF surveyor, Mike Bear, and other San Diego area divers started noticing something unexpected earlier this year -- increasing numbers of encounters with the Bluntnose Sevengill Shark, Notorynchus cepedianus, also known as the Broadnose Sevengill shark. Knowing first hand the impact that divers and snorkelers can have as citizen scientists, Mike set up a website - http://sevengillsharksightings.org -- to serve as a central repository for photographic, videographic and written data on these magnificent creatures. Submissions on the site will allow REEF surveyors who are lucky enough to encounter this prehistoric species to provide additional information and images beyond the sighting and abundance information recorded as part of their REEF survey. It will also enable divers who were not doing a REEF survey to report their encounter. One of the most interesting parts of the website will be the development of an informal photographic database of Sevengill sightings that will facilitate the comparison of photographs and the potential identification of individual sharks using the unique pattern of dark "freckles" on the backs of each shark, similar to the patterns seen on whale sharks. To date, six REEF surveys in San Diego have reported a Sevengill (click here to see the sightings report).
The second annual Abaco Lionfish Derby, held at Green Turtle Cay, Bahamas, on Saturday June 19th, was a huge success. Teams on twenty-one boats from Florida and the Bahamas enjoyed perfect weather and conditions while collecting a grand total of 941 lionfish. Over $5,000 in cash was awarded to the winning teams for the most, biggest, and smallest lionfish. This event, held in the Bahamas and sanctioned by the Bahamas Department of Marine Resources, is one of many REEF efforts to cull invasive lionfish populations and raise awareness about the issue.
The award for most lionfish collected in the one-day event went to team White Roach from Abaco. Repeat winners, the trio of skilled lionfish collectors significantly exceeded their tally from 289 lionfish last year to a whopping 345 this year. This number is both astonishing and alarming when you consider how dense lionfish populations must be for three people to have the ability to collect over 300 lionfish in the span of a single day.
Team Meander from Jacksonville, FL, clenched 1st, 2nd, and 3rd place for largest lionfish collected. Zane Carney captured the largest lionfish ever recorded in the Abacos, which measured just 2cm short of the national record. Zane told Derby organizers that he found a hole outside the main barrier reef off of No Name Cay in 45 feet of water that was full of very large lionfish. He used a pole spear to bag the winning fish, which was 43.4 cm in length (roughly 19 inches long) and weighed approximately 4 pounds.
Lad Akins, REEF’s Director of Operations, and Stephanie Green, a collaborative research partner from Simon Fraser University, recorded valuable data during the event, including lionfish sizes, stomach contents, and sex for many of the lionfish before they were filleted and cooked by the Green Turtle Club. Observers and participants, many of whom had never tried lionfish, found the fish quite tasty, resembling hogfish or grouper. This year, Tropic Seafood Limited of Nassau also arranged to purchase some of the larger fillets of lionfish for distribution in local markets. According to Derby organizer, Bobbie Lindsay, “Tropic’s offer to purchase lionfish is an exciting development, because creating a market for lionfish is the best way to control the population of this invasive fish.”
Thanks to the Derby co-sponsors, Green Turtle Club, and Brendal’s Dive Center, who offered special discounts for Derby participants. REEF also extends sincere gratitude to all of the participants, and especially Bobbie Lindsay, an active REEF member and volunteer who took the lead in organizing the Derby making it a successful event again this year. Next year’s Derby is set for June 24-25, 2011. For full results and pictures go to www.lionfishderby.com.
Summary of Team Results -
REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
This month we feature Horizon Divers in Key Largo, FL. Just down the street from REEF Headquarters, they have been a long-time supporter of REEF’s efforts. One of their hallmark efforts is supporting the REEF Marine Conservation Internship Program by allowing REEF Interns to come out on the boat for free and conduct fish surveys. Horizon dive instructor, Mike Ryan, says, “It’s a lot of fun having them out on the boat regularly and getting to know them. When other divers see their slates and see them tallying fish underwater, they become curious and often ask the interns what they are doing and why count fish. The interns are great because they have the ability to inspire divers to learn fish names and start surveying which, in turn, brings us more business!” Mike also gets into REEF surveying himself. When asked about his best lifetime sightings, he quickly said they were a Manta Ray at one of their popular dive sites and a resident Longlure Frogfish that was regularly surveyed on the Speigel Grove for nearly a two-year timespan.
Horizon Divers regularly teaches fish identification specialty courses and always encourages their students to become REEF surveyors. The shop is also very active in REEF’s Lionfish Control Program in the Keys. Most of their staff have been through REEF’s Lionfish Collection and Handling Workshop and they hold current permits to collect lionfish in the no-take Sanctuary Preservation Areas (SPAs). The dive shop also serves as a Lionfish Collection Bank, collecting, labeling, and storing collected lionfish until they pass them to REEF for research purposes. Mike recently developed a “Lionfish Safari” PADI specialty course. Mike says, “Although lionfish are an ecological nightmare, we are trying to make the best of it by engaging divers in lionfish control efforts and drumming up business at the same time.”
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. Thanks to derby sponsors, including Ocean Reef Conservation Association, City of Layton, Divers Direct, Dive Key West, Spree Expeditions, Markey Marine Services, and The Weekly Newspapers.

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.
