REEF Advanced Assessment Team Member, Dave Grenda, recently co-authored a paper documenting behavioral observations of young Great Barracuda occurring on live bottom sub-tropical reefs primarily at Gray's Reef National Marine Sanctuary off the coast of Georgia. For the past three years Dave assisted University of Connecticut researcher, Dr. Peter Auster, in studying behavioral interactions of piscivores and their prey. During REEF surveys on these cruises, Dave and the other researchers documented young-of-year (YOY) Great Barracuda (those individuals that had very recently settled to the reef, and were between 2-3 inches in length) hunting YOY Tomtate and Silverside that were taking refuge under ledges. Groups of YOY Barracuda would attack, capture, and consume the prey. Prey that escaped the Barracuda retreated to reef edges and were often consumed by bottom-dwelling adult piscivores such as Black Sea Bass, Bank Sea Bass, and Scamp Grouper. These findings indicate that given the strong functional role the young Barracuda have on driving species interactions, greater attention should be given to the roles played by the wider diversity of YOY piscivores recruiting to reef communities. The paper was recently published in the scientific journal Southeastern Naturalist. You can find a link to this and all published papers that have included REEF data on our Publications page.

For more than 20 years, REEF has been conserving marine ecosystems through education, service, and research. It’s an exciting time for REEF as we work hard to extend the reach of our innovative marine conservation programs. One way REEF is doing this is by inviting diverse leaders to the Board of Trustees to help guide the foundation, including these three new members:
Peter A. Hughes is the Founder of the DivEncounters Alliance, a group of independent live-aboard dive operators. Peter is one of the diving world’s foremost live-aboard operators, having spent more than forty years in the dive industry and over the past 25 years, building his former live-aboard company, Peter Hughes Diving, Inc.
Alexander Alexiou, is a successful Broker for Island Real Estate based in Harbour Island, Bahamas. He has traveled extensively and brings unique insight into the culture and ecology of islands throughout the tropical western Atlantic.
Robert Ramin, formerly the Executive Director of the National Aquarium in Washington, DC, is now the Chief Executive Officer of the Washington Animal Rescue League. He has extensive fundraising and membership development experience and has been a leader at the Association of Zoos and Aquariums Management Schools for the past 16 years.
Peter, Alex and Bob join REEF co-founders, Paul Humann and Ned DeLoach, Jim Dalle Pazze, Andy Dehart, Anna DeLoach, and Marty Snyderman on the REEF Board of Trustees. Welcome!
Five days remain in our fundraising campaign to raise $10,000 for our REEF Marine Conservation Internship Program, and we are only halfway there! Help us reach our goal by donating today. Please consider supporting these enthusiastic young professionals as they gain critical career skills and provide REEF with invaluable program support. Although less known, the REEF Marine Conservation Internship Program is one of our most successful endeavors. Our interns are involved in many aspects in the day-to-day running of REEF, and many have gone on to work in academia, at government agencies, or for other ocean conservation non-profits. Your donation will help sponsor an intern, covering living expenses, mentoring and training, and diving opportunities during their four-month experience. To those who have donated already, thank you for making such a tremendous impact on the future of REEF’s interns and aspiring marine conservationists.
REEF Staff Dr. Christy Pattengill-Semmens (Director of Science) and Lad Akins (Director of Special Projects), joined over 300 scientists, resource managers, and fishers at the Gulf and Caribbean Fisheries Institute (GCFI) meeting last week in Corpus Christi, Texas. All three of REEF's major programs were represented.
Christy presented a research poster on an analysis of patterns of rarity in fishes in the Caribbean basin using the REEF Volunteer Fish Survey Project database. Over 90,000 surveys from our citizen science program were used to explore where the rare things are, and why some places seem to have so many more of them than others.
Lad co-chaired a session on Invasive Lionfish, featuring 21 talks on the current state of lionfish research and control efforts in the Atlantic. During this session, REEF Affiliate Scientist, Dr. Stephanie Green, presented her findings on the efficacy of lionfish derbies. Her research shows that one-day derby events like the ones REEF coordinates in Florida and the Bahamas can result in a significant reduction of lionfish densities, up to 70%, over 180 square km, all the result of volunteer teams. Lad and Nova Southeastern University graduate student and upcoming REEF Intern, Adam Nardelli, also presented a research poster on the demographics of participants in the 2013 Key Largo Lionfish Derby.
And finally, REEF Grouper Moon Project collaborators, Dr. Brice Semmens (Scripps Institution of Oceanography) and Dr. Scott Heppell (Oregon State University) both presented talks during the fish spawning aggregation session, and we were also joined by collegues from the Cayman Islands Department of Environment (CIDOE). Brice presented findings from our research using Passive Acoustic Monitoring on a multi-species spawning aggregation on Little Cayman, and Scott presented a theory for why spawning aggregations have collapsed around the world and how our Grouper Moon research can be used to help inform future protection efforts.
A new scientific paper was recently published in the journal Evolutionary Applications that used REEF Volunteer Fish Survey Project. REEF data were used to validate population estimates of Black Rockfish throughout western Canada, Washington State, and Oregon. These results were then used to evaluate the efficacy of marine reserve networks in these areas. The authors of the study estimated the scale of dispersal from genetic data in the black rockfish, and compared this estimate with the distance between Rockfish Conservation Areas that aim to protect this species (essentially evaluating whether the reserves are "connected" enough). Their findings showed that within each country, the distance between conservation areas was generally well connected. The distance between the networks in the two countries, however, was greater than the average dispersal per rockfish generation.
You can read the paper online here. Visit our Publications page to see all of the scientific papers that have been published using REEF data and projects.

We are proud to release REEF's 2014 Annual Report, reviewing accomplishments from our ocean conservation and education programs. Click here to view the Annual Report. In the report, we highlight many achievements and successes in 2014, such as:
REEF was founded in 1990, out of growing concern for the health of the marine environment and the desire to provide ocean enthusiasts with ways to actively contribute to improved understanding and protection of marine environments. Looking back on more than two decades of hard work, REEF’s impact is remarkable. The most important part of this grassroots organization has always been the members who make it possible. Whether you’ve been with REEF since it was founded, joined in somewhere along the way, or just became a member this year, we are profoundly grateful the time, skills and financial resources you give to make such a significant difference in marine conservation.
While we can't do much about dreary winter weather, booking a trip for the coming year might be just the trick to lift your mood. REEF trips are a diver's dream vacation! We have two great trips in February - a fish ID trip to Barbados and a lionfish research trip to Dominica. Trips later in the year include Belize, Saba, Bermuda, and more.

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:
- Data from St. Eustatius and St. Martin were provided to a scientist at the Sustainable Fisheries Group at UC Santa Barbara.
- Parrotfish and surgeonfish sightings data from the Caribbean were provided to scientists from Avanzados del I.P.N-Unidad Mérida, a university in Mexico, to evaluate trends in these important reef herbivores.
- A graduate student at University of British Columbia is using REEF data from the Pacific Northwest to evaluate regional fish and invertebrate assemblages.
Over 60 scientific publications have included REEF data. Find out more at www.REEF.org/db/publications.
