It was a science lesson with a difference, broadcast live from beneath the waves with thousands of endangered fish in attendance. Earlier this month, Grouper Moon Project scientists, Dr. Brice Semmens from Scripps Institution of Oceanography, and Dr. Christy Pattengill-Semmens from REEF, hosted three live-from-the-field web chats with students from 18 classrooms at 13 schools in the Cayman Islands, The Bahamas, and Washington State (US). The first of the three web chats was broadcast from the Grouper Moon base of operations on Little Cayman, and featured scientists explaining the research objectives, day-to-day activities, and research equipment used during the project. The other two featured Brice diving and answering questions from the students, first on the Nassau Grouper spawning aggregation and then on the famous Blood Bay Wall. The webcasts are archived online here.
Now in its third year, the Grouper Education Program presents students with a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important species. Key curricular concepts include: the historical role of Nassau Grouper in the Caribbean, its role as a top predator and its positive impact on local reef health, and the conservation challenges facing the species.
Brice Semmens, who presented the underwater webcasts, said students were excited to witness science in action. “As they explore the aggregation with me, the immediacy and reality of the experience really touches them. We are giving students their first diving experience – and it happens to be with thousands of huge, endangered reef fish.”
The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support is provided by Southern Cross Club, Little Cayman Beach Resort and Reef Divers, Cayman Airways, and LIME.
REEF staff co-authored a new publication in the scientific journal PeerJ that features research findings from our Invasive Lionfish Research Program. The paper, titled "Setting the record straight on invasive lionfish control: Culling works", evaluates the effectiveness of lionfish removal efforts. Frequent culling of the invasive Indo-Pacific Lionfish throughout the Caribbean has been shown to cause a shift towards more wary and reclusive behavior by lionfish, which has prompted calls for halting culls. The paper addresses those concerns and reviews research conducted by REEF and other efforts. Culling successfully lowers lionfish numbers and has been shown to stabilize or even reverse declines in native prey fish. Partial culling is often as effective as complete local eradication, yet requires significantly less time and effort. Abandoning culling altogether would therefore be seriously misguided and a hindrance to conservation. The authors also offer suggestions for how to design removal programs that minimize behavioural changes and maximize culling success. The paper is available for online viewing here. You can find a complete listing of all publications that feature REEF's programs at www.REEF.org/db/publications.
Here are a few notes and news bits we'd like you to know about:
Four spots recently opened on our Turks and Caicos Field Survey aboard the Aggressor II, April 19-26, 2008. This is a wonderful opportunity for new and experienced REEF surveyors to spend a week diving in one of the jewels of the Caribbean. You can take advantage of our live-aboard accomodations and make up to 5 dives per day at all the best sites these islands have to offer.
There are quite a few expert surveyors on this trip, so if you're a beginning surveyor, you'll have plenty of mentorship and you could even work toward becoming an expert by the end of the week. For our experts, there are many cryptic species to challenge us on our surveys. We will have a number of REEF Fish ID classes and time to catch participants up on the many exciting upcoming REEF projects worldwide for 2008.
To reserve your spot - please call Joe Cavanaugh at 305-852-0030, ext. 3 or Tami Gardner at Travel for You, 1-888-363-3345, For more information about the trip, please visit our Field Survey page atField Survey page Hope you can join us!
In response to the growing threat of lionfish in the Atlantic and the need for coordinated planning, REEF, NOAA and the USGS are hosting a technical workshop on Non-native Marine Fish Introductions of South Florida in the Florida Keys June 18 and 19. The workshop, jointly funded through a recent Mote Marine Laboratory’s Protect Our Reefs grant, NOAA’s Exotic Species and National Marine Sanctuary Programs and the Gulf and Atlantic States Regional Panel on Aquatic Invasive Species,will bring together personnel from more than 18 different agencies and organizations. Plans for the workshop include presentations by State and Federal agencies, breakout groups and round table discussions that will focus on disseminating the most current information, and drafting a coordinated plan of early detection, notification, and rapid response.
Lionfish have been recorded in large numbers from North Carolina through the Bahamas and are rapidly expanding into the Caribbean. Fortunately, the fish have not yet shown up in the southeast Florida reef tract including Biscayne National Park, the Florida Keys National Marine Sanctuary and the Dry Tortugas National Park and Ecological Reserves. This planning workshop will endeavor to put in place mechanisms to help minimize lionfish impact in these treasured marine protected areas. While lionfish are the “poster fish” of invasive species, the protocols developed in this workshop will be widely applicable for sightings of other non-native marine fish as well, with the goal of preventing future invasions by other species.
REEF will continue to host training and planning workshops, as funding allows, to help downstream countries plan for the arrival of lionfish. Efforts to control populations and minimize impactswill be highlighted as research answers key questions and we are able to develop control methods. To find out more about REEF's Exotic Species Program, contact Lad Akins, Director of Special Projects.

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.
