A new scientific paper that features research from REEF's Grouper Moon Project, "Hot Moments in Spawning Aggregations", was recently published in the journal, Coral Reefs. The study looked at the impact of a Nassau Grouper spawning aggregation in creating biogeochemical "hot moments", which occur when a temporary increase in one or more limiting nutrients results in elevated rates of biogeochemical reactions. In this case, the limited nutrients are nitrogen and phosphorus. And the temporary increase is from the large amount of grouper excrement that results when approximately 5,000 Nassau Grouper gather in a small area for 10 days during the spawning season, as happens around winter full moons on Little Cayman. The authors estimated the rate of nutrients supplied by the Nassau Grouper at the Little Cayman aggregation site, and found that the temporary surge in the nutrient supply rate was larger than nearly all other published sources of nutrients on coral reefs, an ecosystem that is typically a food and nutrient desert. Beyond the loss of this iconic species in the Caribbean, the significant decline in Nassau Grouper and their spawning aggregations over the last few decades has likely had large consequences on the productivity of the reefs that historically hosted spawning aggregations.

Thanks to everyone who participated in a GAFC event this summer! This July, over twenty-three events were hosted throughout REEF's survey regions. We are still receiving data from these events and have processed a large amount already!
Since REEF's GAFC's inception in California in the early 90's, it has continued to grow and expand. More people are become involved in REEF by making a meaningful contribution to marine conservation by conducting REEF Fish Surveys. Previous events have generated over 2,000 surveys during the month of July. This year, the New England Aquarium Dive Club hosted an event in Gloucester, MA, with 103 surveyors!
GAFC is REEF's biggest annual signature event which mobilizes our wonderful partners, volunteers, and dive shops throughout much of our survey regions. All of whom coordinate their own local events which include offering free REEF Fish ID courses, organizing survey dives/snorkels, and other fun events tied into the theme of counting fish. The GAFC draws local, national (US), and international media attention each year. It reengages veteran REEF volunteers and also serves as a terrific mechanism to expose new ones to what REEF is all about. Though the GAFC takes place each July, it highlights nothing more than what we do year-round - engaging individuals to become active stewards of the marine environment. Volunteers learn by taking REEF Fish ID courses and conducting fish surveys as part of The Fish Survey Project.
Grant Gove, who attended the GAFC event hosted by the Yellow Submarine Dive Shop in Bonaire, Netherlands Atillies, sent REEF wonderful DVD's of their successful event for our public library! If you hosted an event this year, or participated in one, we encourage you to either mail a DVD to REEF HQ, Post Office Box 246, Key Largo, FL 33037 or email your pictures to email@example.com.
Thank you to everyone who made GAFC successful this year and look forward to next years 17th annual GAFC event!
The long wait is finally over! REEF is proud to announce the launch of an expanded online data entry interface that now includes surveys conducted in the Pacific (California – British Columbia) and Hawaii regions. Surveyors in these regions can now enter data online and enjoy quicker processing time to view their data. With more than 2,000 survey forms coming in to REEF HQ each month, this expanded service will both improve efficiency and reduce rising costs of processing data. The program will eliminate many of the common clerical errors and will flag potential species misidentification based on existing REEF sightings data. REEF originally launched online data entry for surveys conducted in the Tropical Western Atlantic region (includes East and Gulf Coasts of US, Caribbean, Bahamas, and Bermuda) in February 2005. Here are answers to some of the most common questions
When and how?
Starting today, members can go online to http://www.reef.org/dataentry and enter data for surveys conducted anywhere in these Volunteer Survey Project regions. You will log in using your REEF member number and last name.
Will the data immediately be added to the REEF database?
No, similar to data submitted via paper scanform, REEF staff will run the data through error checking programs first. However, overall processing time will be greatly reduced.
Will I still be able to submit data using the paper scanforms?
Yes, REEF will continue to provide and process paper scanforms. However, beginning in 2008, REEF will charge a nominal fee per paper scanform to cover rising costs in processing these paper forms.
A very big thank you to Dr. Michael Coyne, REEF’s longtime database programmer and overall IT guru, for making this new program a reality, and to stellar REEF volunteers Janna Nichols, Liz Foote, Carl Gwinn, Herb Gruenhagen, and Janet Eyre for their help in beta testing the program.

It is hard to believe that I am already more than half way through my Marine Conservation Internship. The past two months have been full of exciting events that have really inspired me to continue on in the world of marine conservation and biology. After settling into the REEF office for just a few days, the REEF staff had me out and about, getting involved with the community. For a week in mid-June I assisted with Paul Humann’s “Discovery Tour,” diving along side an energetic and enthusiastic group of divers who were learning fish identification and practicing surveying techniques. I was also able to sit in on the Non-Native Marine Fish Introductions of South Florida Technical Workshop, which helped introduce me to the growing problem of Lionfish and the efforts that REEF, along with other organizations, puts forth into researching this growing problem.
July has been just as busy, starting with the International Coral Reef Symposium from July 7-11. This conference happens only once every four years, and fortunately for me, was held in Ft. Lauderdale this year. I had never had the opportunity to attend a scientific conference like this before, but was a great experience due to the many presentations and massive amounts of information I was exposed to each day. It really helped to open my eyes to the different fields of research available. Following the symposium, I was able to participate in the REEF Field Trip associated with ICRS in Key Largo.
I have also been able to work with the Education and Outreach program during my time with REEF. As part of REEF’s Great Annual Fish Count, I participated in a Fish ID Seminar at Biscayne National Park. I also spoke to volunteers at the Dolphin Research Center about REEF and its programs while visiting the facility and learning about the center in June. After hearing many great stories about the infamous Seacamp from Lisa, I spent my first night on Big Pine Key just last week where Lisa and I were the Science Night speakers for a group of campers. The enthusiasm in the room from the kids was off the charts and great to see.
One last highlight of my time with REEF thus far was being able to meet with George Wozencraft, the Internship Coordinator for the Our World-Underwater Scholarship Society that sponsors my Marine Conservation Internship with REEF. I was able to dive with George one afternoon and discuss my internship and many of the opportunities I have had so far. I am looking forward to the upcoming weeks I have left with the REEF staff, and of course, getting out in the water to conduct more fish surveys!
While we all knew it was just a matter of time, the call still came with a bit of surprise and dread as the first confirmed lionfish sighting in the Florida Keys came in on January 6th, 2009. REEF member Becky Fowler, from Greenville, SC, was diving just offshore of the Benwood Wreck in Key Largo when she spotted the invasive lionfish near the base of a ledge at 66'. With all of the recent focus and outreach efforts that REEF has been forwarding to our members, she knew immediately that she needed to document the sighting and gather a detailed description of its location. Upon her return to shore, she called REEF HQ and delivered the report. This set into motion the Rapid Response plan
developed 7 months earlier in a REEF sponsored multi agency workshop (see REEFNotes article). Becky came by the REEF office, the images were verified, and her detailed site description was conveyed to Lad Akins, Director of Special Projects. The report was forwarded to the US Geological USGS alert system and Lad began response coordination with the Florida Keys National Marine Sanctuary (FKNMS) who has jurisdiction of resources at the sighting location.
The following morning, the response team made up of Lad Akins, Lisa Mitchell (REEF Exec. Dir.), John Halas (FKNMS), Frazier Nivens (Ocean Imaging) and Steve Campbell (Quiescence Diving Services) were assembled and on site at 10:30am. Following the excellent location description provided by Becky, the team was able to locate the fish, capture video footage, gather important data on site characteristics and the available nearby prey community, capture and bag the fish in under 14 minutes. The fish was captured live via hand nets, brought back to shore, euthanized and dissected. The 99mm immature male contained one 34mm prey fish in its stomach. Tissue samples, genetic material and other measurements were collected for further analysis by researchers at the NOAA Beaufort lab and Simon Fraser University. No other lionfish were found in the immediate vicinity.
While no one wanted to see lionfish show up in the Florida Keys, most knowledgeable sources believed it was inevitable and simply a matter of time. The one bright side of this story is that advanced planning and preparation initiated by REEF resulted in the awareness, accurate reporting, and successful rapid response effort that removed the fish less than 24 hours after its initial sighting. Hopes are that as lionfish show up in the Keys and other downstream areas, these rapid response efforts will help to control establishments and minimize impacts of this glutinous predator.
REEF continues to encourage divers to report their sightings of lionfish and other non-native fishes with as much detail as possible to www.reef.org/lionfish and to support lionfish research projects such as the January 17-24 project in the Turks and Caicos and the June 13-20 project in Belize. For more information, contact Lad Akins (Lad@REEF.org) (305) 852-0030.
If you are a REEF surveyor in the Tropical Western Atlantic, you are probably familiar with the Peacock Flounder (Bothus lunatus). And if you spend much time in the sand, you probably even know about the smaller Eyed Founder (Bothus ocellatus)? But how about the Spiny Flounder (Engyophrys senta)? Danielle Calini, an Our World Underwater Scholar who spent this summer as an intern at REEF HQ in Key Largo, was one of several REEF surveyors who recently came across this rarely seen species during a dive on Molasses Reef. And while this was the first record of the Spiny Flounder in the REEF Florida Keys database, it turns out this species might not be as rare as we think.
Spiny Flounder are very similar in appearance to the common Eyed Flounder, and it's likely that surveyors might not be looking closely enough when they see the small flatfish scurrying across the sand. It was previously thought that cirri extending from the eyes were a key feature distinguishing the two species but the cirri are very difficult to see. According to Paul Humann, Spiny Founder can be distinguished from Eyed Flounder by three key features:
REEF is proud to host an Our World Underwater Scholar each summer. In addition to tracking down rare species, OWU interns provide much needed help in the REEF HQ office and conduct outreach with the Florida Keys community. The REEF Staff and Board of Trustees extends a big fish thank you to Danielle in appreciation for her service to REEF in the Summer 2009.Share on Facebook
In April 2009, REEF started a monthly seminar series to give back to the community that has housed and supported REEF since our inception. REEF Fish & Friends gathers snorkelers, divers, and armchair naturalists at REEF HQ in Key Largo to learn more about fish and have some fun. The July seminar for REEF, Fish & Friends was all about the Great Annual Fish Count (GAFC). Lad Akins, REEF Director of Operations, presented a brief overview of the event and its’ 18 year history.His enthusiasm and humor encouraged participants to get involved in the annual event with the hope they will continue to conduct fish surveys and contribute to REEF’s database year-round. The How, When, and Where of conducting a survey was explained and the materials needed were shown.
Several of the people attending the seminar brought in Lionfish along with the data regarding their capture. Lad briefly updated the audience on the status of the Lionfish in the Florida Keys and thanked the local dive community for their ongoing efforts in controlling this invasive species. Zach Bamman, REEF’s summer intern, offered to dissect one of the freshly caught Lionfish and this generated a lot of interest. He is a Senior at the University of Central Florida, majoring in Environmental Sciences.
The August REEF Fish & Friends will feature Lauri MacLaughlin from the Florida Keys National Marine Sanctuary. Her presentation entitled “SPAWN-TANEOUS Corals Catch the Corals in The Act" , will document the annual spawning event over the last 14 years through lecture and video presentation. This is big summer event and Lauri will educate divers prior to their night dive so they will fully appreciate what they are about to see.
REEF Fish & Friends is held the second Tuesday of each month from 6:00 PM to 7:30 PM at the James E. Lockwood REEF Headquarters at MM 98.3 Key Largo. We invite everyone to stop in and share some food, drink, good conversation, and hear a relevant topic about REEF’s projects or a mini fish ID seminar.
REEF announces the release of "The Lionfish Cookbook", available for $16.95 online at http://www.reef.org/catalog/cookbook. The book is a unique blend of 45 tantalizing recipes, background on the lionfish invasion and its impacts, as well as information on how to safely catch handle and prepare the fish. Invasive lionfish are a new threat to western Atlantic, Caribbean and Gulf of Mexico waters. Lionfish densities in the Caribbean, Gulf of Mexico, and the East Coast of the United States are on the rise due to their lack of predators and prolific, year-round reproduction. Thriving lionfish populations pose a serious risk to marine ecosystems through their predation on native marinelife including both commercially and ecologically important species. That lionfish are delicious table fare with a delicate buttery flavor may be our best hope for helping to remove the fish and minimize its impacts. As Bermuda has so aptly coined, we need to “Eat ‘em to Beat ‘em”! Proceeds from the sale of this book will support REEF’s marine conservation and lionfish research and removal programs.
We are happy to share with you a short (3-minute) Public Service Announcement (PSA) from the REEF Grouper Moon Project, featuring spectacular underwater footage and the hopeful story of the Nassau grouper in the Cayman Islands. The video discusses the importance of protections for spawning aggregations and the work that REEF and our collaborators at the Cayman Islands Department of the Environment (CIDOE) and Oregon State University have done on this important conservation issue. The PSA is on REEF's We Speak Fish YouTube channel -- http://www.youtube.com/user/WeSpeakFish
Cayman Island spawning aggregations have been seasonally protected from fishing for the last 8 years at all current and historic aggregation sites. This protection expires at the end of 2011. The status of future protections for the aggregations is still uncertain. Based on the research and findings of the Grouper Moon Project, the CIDOE has recommended a permanent seasonal closure during the spawning season (Nov-Mar) for Nassau grouper.
