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.
REEF members are at the heart of our grassroots marine conservation programs. Over 40,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Pam Wade (member since 1998). Pam lives in California and has 381 REEF surveys under her belt as a level 4 surveyor. Through REEF, Pam’s interest in fishwatching has encouraged her not only to dive more, but to explore the world’s oceans in other regions. Earlier this month, Pam was on a REEF Field Survey in the Sea of Cortez with REEF scientists, Drs. Christy and Brice Semmens. Here’s what Pam had to say about diving with REEF:
What is your favorite thing about being a REEF member?
When you join REEF you have the opportunity to do more than just send in a donation and get a beautiful calendar. You actually get to be an active participant in fulfilling the mission of conserving marine ecosystems. I love feeling that my dives have a purpose. You don't have to change the way you dive, the only difference is that you know what you are looking at, you see a lot more and the enthusiasm transfers to everyone you dive with. Pretty soon, everyone wants to know the names of the fish and everyone is learning and appreciating and protecting the treasure we have under the sea!
What was your experience with REEF trips?
The very first trip I signed up for was a REEF Discovery trip to Bonaire with Paul Humann in July 2001. Those classes gave me a good foundation in fish identification: what to look for, where to look, fish anatomy and the identification clues that really matter. Paul pointing out a Yellow Tube Sponge, said you can always add one more fish to your survey; those sponges are home to the Short Striped Goby! I met Ann B. from Arkansas on that trip, and I’ve been following Ann across the oceans identifying fish and invertebrates ever since. In August 2008, I participated in the REEF Critter trip to Saint Vincent with Paul and Ned. That’s where I passed the level 3 test. Bill Twees was invaluable in his help pointing out the Black Brotula, Sunshine Fish, Flag Fin Blenny…..I’m looking forward to diving Saba with REEF in 2011!
Do you have any surveying tips to pass along to other REEF surveyors?
Lately I have been working on ways to more efficiently record my survey information on my slate to ensure that it’s complete and ready to enter on the computer when I get home. As part of this, I’ve been using the various tools and reports available on the REEF website, including the Geographic Zone Reports for the specific area that I am going to dive and the Geographic Zone Code lists with site names. This gives me more time between dives to enjoy getting to know the other divers and identifying fish for everyone else onboard. The enthusiasm is catching! Why else would a dedicated photographer on the Sea Hunter at the Cocos Islands be excited enough about capturing a Cocos Barnacle Blenny feeding that they missed the whale shark passing overhead?
We are pleased to announce the 2012 REEF Field Survey trip schedule. We have an exciting lineup of destinations planned and we hope you will join us. These trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. REEF staff, board members, and other REEF instructors lead these trips, and each features daily classroom seminars and a full diving schedule. 2012 destinations include: Nevis, San Blas Islands in Panama, Dominica, Sea of Cortez, Hornby Island in British Columbia, Bermuda, the British Virgin Islands, and Cozumel.
