Here are a few notes and news bits we'd like you to know about:
On Saturday, February 9, REEF hosted the first annual For the Love of the Sea benefit dinner and auction at Amy Slate's Amoray Dive Resort in Key Largo, Florida. The event was a huge success! More than 150 guests attended a sold-out event, enjoying a picturesque sunset set to island music and the awe-inspriring underwater photography of authors and REEF founders, Paul Humann and Ned DeLoach. REEF raised more than $25,000 thanks to successful silent and live auctions and the generosity of event sponsors in the Keys and greater REEF community. Proceeds of the event will support ongoing citizen science projects to engage volunteers in marine conservation.
Many thanks to event sponsors for their support and to the local REEF "Fun Raisers" event planning committee. Please click here for more information on the event.
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 United States Geological Service (USGS), the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. As part of REEF’s Lionfish Research Program, over the last two years REEF has coordinated 12 research projects that have involved over 175 REEF volunteers. This research has generated a wealth of in-situ observations and over 1,000 lionfish specimens, which have led to great advances in the understanding of the biology and potential impacts of this most unwanted invader.
REEF’s 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. Findings included:
Lionfish continue to grow in size: Tagging data show growth rates exceeding 190mm/year, far larger than necessary to reach sexual maturity.
Site Fidelity: All 12 previously-tagged specimens that have been recaptured indicate strong site fidelity even after 6 months.
Prey: Lionfish continue to amaze us during stomach content studies. The recent effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. Lionfishare eating nearly anything that will fit into their mouths.
Reproduction: Lionfish reproduction occurs throughout the year – many gravid females and a small recently settled juveniles have been found.
REEF’s future fieldwork 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.

The USS Hoyt Vandenberg is the most recent ship to be placed as an artificial reef in the waters off Key West, Florida. The ship was sunk on May 27, 2009, but three weeks prior to the sinking the REEF team was in action conducting surveys of the sinking site and 7 other adjacent sites for comparison. The data will be used by the State of Florida to document fish recruitment onto the wreck and response of nearby reef sites to the new structure. In addition to regular REEF fish surveys, the team is also gathering important fish biomass data at two sites and recording any observations of non-native titan acorn barnacles, orange cup corals or non-native fish including lionfish.
The pre-deployment surveys at the sinking site did not document any fish present at the sandy bottom site though one barracuda was seen swimming through the area shortly after. Combined data from the 7 reference sites documented 159 species including rare sightings of pugjaw wormfish and cherubfish (rare for the Keys). The summary of data can be found here.
REEF will continue regular monitoring of the Vandenberg and reference sites through next summer, with a final report due by the end of 2010. A huge thank you to all of the REEF experts joining in on the effort including Rob McCall, Tracy Harris, Dave Grenda, Brenda Hitt, Jamie Giganti, Lisa Canty and Pat Zuloaga.
Earlier this month, on World Oceans Day, we kicked off REEF's Summer Fundraising Campaign with a goal of raising $60,000 by July 31. Thanks to the Curtis and Edith Munson Foundation, who has generously offered to match your donations, we are over one-third of the way to our goal with $10,345 donated and matched so far. To all of our members who have already donated, we extend our sincere gratitude. If you haven't yet had a chance, please contribute today. You can double your donation in the upcoming month by contributing online, https://www.REEF.org/contribute, through our secure web form. Or you can print the donation form and mail or fax your donation, or call our staff at REEF headquarters (305-852-0030).
Your donation will help support REEF services, which are increasingly in high demand. As the lionfish invasion continues to grow, so does our research and response. Legislation to ensure long-term protections of Nassau Grouper spawning aggregations are set to expire in 2011. And after the devastation in the Gulf, REEF’s Volunteer Fish Survey Program data can be invaluable in evaluating the impact of the oil spill to fish populations. Twenty years of support from members like you has made it possible for REEF to build and maintain this valuable history of fish populations throughout our program regions. We could not do this vitally important work without you. We are doubling our efforts now, and we hope you will double your contribution this summer.
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:
- Researchers at the World Resources Institute are using western Atlantic REEF data in an analysis of threats to the world’s coral reefs called Reefs at Risk Revisited.
- A scientist from Washington Department of Fish and Wildlife is evaluating population trends of rock scallop in preparation for harvest rule updates.
- Researchers from the Puerto Rico and US Virgin Islands GAP Analysis Project are creating species range maps that will be used with habitat information to model species distributions. The goal of this project is to keep common species common by identifying those species that are not adequately represented in existing conservation places.
- A researcher from Cascadia Consulting Group is using data on three invasive tunicate species collected by REEF surveyors in the Pacific Northwest to prepare for a baseline assessment for the Washington Invasive Species Council.
REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Itziar Aretxaga (REEF member since 2003). Itziar has conducted 263 REEF surveys in three REEF regions, and she is a member of the Advanced Assessment Team in the Tropical Western Atlantic. Here's what Itziar had to say about REEF:
When and how did you first volunteer with REEF?
Shortly after I got my C-card I started looking for a good reference book on fish. I was fortunate to find Paul Humann and Ned DeLoach´s reef guides, and there I read about the REEF program and how one could volunteer. I joined and started identifying species and reporting them to REEF on my own. A year later I met Lad Akins in a course he gave to volunteers in the Veracruz National Park, and he taught me a few tricks that improved my identification skills. He has been a great mentor in all my fish watching activities ever since.
What inspires you to complete REEF surveys?
I often look at the online database to check what I might be missing, and the only way of improving it is for each of us to submit our surveys, even if that means clicking on the box for Yellowtail Snappers over and over again. I keep telling myself that I hope I will never see the day when I miss them because they are no longer there. I also take special pride when our data are used in scientific publications or management reports. It might be a mere dot in a plot, but collectively we contribute to the growth of knowledge on marine life and conservation.
Do you dive close to where you live? What is the best part about diving there?
I have done over 200 surveys in Veracruz and I know it well enough now that I can recognize changes. I enjoy noticing the unusual species, species off-season, and it is really thrilling when I get to report a new species. There is also the challenge of spotting fish that others have reported that I have yet to see, so the fun continues.
What is your most memorable fish find?
The first Smooth Trunkfish in golden variation I saw in Veracruz, and the first time it was reported outside the Northern Gulf of Mexico by REEF members. I was so excited when I saw it that I started dancing underwater, quite literally. The staff in our local diving shop told me afterwards they were not that unusual in the area. It was just that nobody had reported them before.
What is your favorite part about being a REEF member?
I like sharing with others the fun of it. I usually take surveys during commercial diving boat trips, and people are curious about those slates that I take underwater and keep scribbling on. It is great to see some of them then turn to my book, and start calling each other to show what they themselves have seen.
REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
Our Outstanding Field Station this month, Seattle Scuba, is based in the always-green but often-rainy Pacific NW. Yes, the water's cold there. Seattle Scuba is a full service facility that provides training, equipment rentals/sales, fun dives and more - all served up with an ample helping of personality and humor to their customers and friends. They are passionate not only about teaching diving, but about instilling awareness of the marine environment in divers. The REEF survey program is an ideal tool in this mission. Their training director/resident mermaid Heidi Wilken got involved in REEF surveying after encountering some fish geeks on a fun dive one day. Wanting to incorporate and support REEF's mission she decided to provide resources at Seattle Scuba. They have been a Field Station for about 4 years now. Now two of their training staff are REEF Advanced Assessment Team members (Heidi and David Todd). They hold periodic Fish Geek Dives, fish & invertebrate ID Classes, testing to move up in REEF Experience Levels, and offer a full range of Fish ID books for sale.
Heidi had this to say about Pacific NW diving: "Sometimes people look at Puget Sound and surrounding areas and think it will just be cold and dark - they have no idea of the colors and amazing critters that lurk beneath the surface! We are blessed to have not only lots of amazing and cool fish like the Red Irish Lord and the Pacific Spiny Lumpsucker, but also incredible invertebrate life, from the Giant Pacific Octopus to the tiny Opalescent Nudibranch." And what does Heidi like best about REEF? "You don't have to be a scientist to be involved, even if you can only identify ONE fish or invertebrate, you can contribute surveys - and you can do so to whatever level fits into your life, be it a survey a year or 200 a year." Her parting words: "Dive safe and survey often!" Thanks Heidi and the staff at Seattle Scuba - we're glad you're a REEF Field Station!
