REEF Grouper Moon scientists co-authored a recent groundbreaking paper in the journal PLoS One that highlights the importance of regional conservation efforts aimed at spawning aggregations in the Caribbean. This study evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean using DNA markers. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean. These results suggest that, despite a lack of physical barriers, Nassau Grouper form multiple distinct sub-populations in the Caribbean Sea. Oceanography (regional currents, eddies) likely plays an important role in retaining larvae close to spawning sites at both local and regional spatial scales. These findings highlight the importance of conservation initiatives such at REEF's Grouper Moon program in the Cayman Islands. A PDF of the paper is available online here. You can see a complete list of all scientific papers that have included data from REEF programs at www.REEF.org/db/publications.

This month we highlight Nick Brilliande. He has been a REEF member since 2011. An active surveyor who lives on Oahu, Hawaii, Nick has conducted 50 surveys to date and is a member of REEF's Advanced Assessment Team for the Hawaii region. Here's what he had to say about REEF:
How did you become involved with REEF?
The first time I heard about REEF was through a group called Reef Watch Waikiki. I attended some talks by REEF members Cassidy Lum and Jennifer Barrett describing what REEF does and how to survey fish. I answered a few questions and made some comments on fish, which impressed both Cassidy and Jen. Then came the time to try it out and I did. I had fun doing it, but it was also an excuse to look at fish, which I always find fascinating. After that, I became a member, went out to survey when I could, and slowly made my way up to an Expert Level 4/5 surveyor.
What inspires you to complete REEF surveys? What is the most interesting thing you learned doing a REEF fish survey?
I am always curious as to how the environment changes over time and how those changes affects the species that live there. The ocean is always different every day in some way or another; you never have the same type of conditions or species.
Do you have any surveying, fishwatching, or identification tips for REEF members?
When doing a fish survey, having an extra pair of eyes does help, but you want to be patient. The fish initially view you as a threat, but wait a little and eventually they will get used to you enough to come out and be able to see them. Let the animals make the first moves.
When learning fish for the first time, do not jump around families. The only thing that will accomplish is a huge headache. Take one family, learn the different species of fish one at a time, then quiz yourself to see if you actually know one species from another. Rinse and repeat. As long as you are out and about, you will never forget a fish's face. As mentioned, patience is key. Let them come out on their terms and let them make the first moves. One thing that seems to work for me is keeping my hands and arms to my side while snorkeling or diving - fish seem to view this as less threatening than flailing arms back and forth or having arms wide out.
What is your most memorable fish find and why? Is there a fish you would really like to see?
There are a few finds I remember. One was in Pokai Bay on O'ahu. Here, I witnessed a female Whitley's Boxfish picking at a turtle with a large tumor beside his mouth. This fish was picking at the tumor, but I still have no idea as to the purpose of this. At this same location on the same day I found my first lobster molt, a Slipper Lobster molt. Another encounter I still remember is in Kealakekua Bay on the Big Island of Hawaii. There were three notable encounters on the same day: two Longnose Butterflyfish, one of which was in a rare dark coloration alongside the other, which was in it's typical yellow coloration, a partial albino Yellow Tang in very shallow water, and a very sleepy Whitetip Reef Shark, which I was able to get very close to without disturbing him.
As far as animals I would like to see, that list would be almost half a page long. A few notable ones would include a Whale Shark, a Dragon Moray Eel, a Hawaiian Monk Seal underwater (I've seen them numerous times on beaches or them swimming around viewed from a boat or shore), and a Hawksbill Sea Turtle.

If you’ve read recent REEF releases, you’ve heard the news that Indo-pacific lionfish are now well established along the eastern US coast and throughout the Bahamas. REEF has been and continues to work with researchers to learn as much as we can in order to most effectively address the invasion. Since January of this year, REEF has organized and led 5 week-long projects in the Bahamas to document the extent of the invasion and gather samples and information needed by NOAA and Bahamian researchers.
Here is what we’ve found:
Here is what we are working on with NOAA and Bahamian researchers:
As part of this effort, REEF has planned more research efforts through the end of 2007. Each project will include participation of scientists, researchers, and/or REEF staff. For a list of upcoming projects visit http://www.reef.org/exotic/lionfish/ or e-mail firstname.lastname@example.org
Here's what we're up to in the coming months:
October 31- November 3: DEMA Show in Orlando, FL. Come visit us at both 1133 and you could win a signed print by Tom Isgar by partaking in our DEMA raffle to help raise funds for REEF.
November 11-17: Conservation Week with Stuart Cove's Dive Bahamas in Nassau with Ned and Anna DeLoach, Bruce Purdy and Andy Dehart
Recent additions to the previously planned Eco-week at Stuart Coves Dive Bahamas in Nassau will be highlighted by Ned and Anna DeLoach, who will be presenting their famous behavior talks as part of the week's activities. In addition, Andy Dehart, general Manager of the National Aquarium in Washington DC and Bruce Purdy, Bahamas dive operator and conservationist will talk about Bahamian conservation issues and marine protected areas. As previously planned, Lad Akins will lead the project and discuss lionfish issues as they relate to other environmental factors such as artificial reefs. Stuart Cove will host the project and discuss shark and local conservation issues.
December 8-14: Blackbeard's Cruises is announcing a new lionfish project focusing on Grand Bahama.

Once again, CEDAM International is offering two scholarships for educators to participate on a REEF Field Survey. For the 2008 survey season, the scholarships will apply to the Gran Bahia Principe Field Survey in Akumal, Mexico. Dates for this trip are May 17-24, 2008. You can visit REEF's Field Survey page to view trip details and also check out the trip flyer. To apply for this scholarship, please visit the CEDAM website at then click on the Lloyd Bridges Scholarship tab at the top of the page to see details.
The two scholarships enable qualified educators to participate - at no cost - in a CEDAM-sponsored or -sanctioned expedition. This REEF Field Survey will be led by Joe Cavanaugh, REEF Field Operations Director. Participants will have the opportunity to collect data, participate in daily talks, and interact with REEF members, staff, and local organizations. This will be a hands-on experience during which participants have the opportunity for fish identification and marine conservation training in and out of the water. REEF has partnered with ReefAid and Reefcheck and Ecologica Bahia in 2007 to assist Gran Bahia Principe Resort with developing a monitoring and assessment protection plan for their nearshore reefs. Our cooperative efforts in conservation at Bahia Principe are making a difference in protecting their reefs and some of our class time will focus on these successes.
To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization.The scholarship will be awarded on the basis of both merit and financial need. CEDAM International will cover the recipient’s airfare and REEF Field Survey expenses (excluding incidentals and personal expenses), on this educational adventure. Bahia Principe is an all-inclusive resort so acoomodation, diving, and meals are included. The application deadline will be earlier than last year's deadline since the Field Survey pariticipation dates are in late May this year. Please have your completed applications submitted by April 1, 2008.
Many of our members may be too young to have seen the television program, Sea Hunt, starring Lloyd Bridges that ran from 1958-1961. One important aspect of the series was that Bridges made a plea at the end of each episode to protect the oceans, an early ocean conservation pioneer. He was also involved in several organizations including the American Oceans Campaign and Heal the Bay, a Los Angeles-based conservation group. He inspired a generation of SCUBA divers and you may want to check out Wikipedia to read more about many of the people Bridges worked with on Sea Hunt. Incidentally, I discovered that Bridges learned to SCUBA dive once contracted for the show and that he was offered the role of Captain Kirk before William Shatner!
There are still spaces (4) available for the Akumal Field Survey, email email@example.com to inquire.
All applicants must complete an application form and return it along with the required essay and two letters of recommendation, to CEDAM (by mail or electronically) by April 1, 2008. Good Luck!
As many of you are aware, 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 USGS, the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem.
Our 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. To wit:
To date, dive operators and the contributions of participating volunteers have funded the bulk of this work. REEF’s future field-work 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. For additional information, please contact Lad Akins at (305) 852-0030 x-2# or e-mail Lad@reef.org
As Fall is upon us, we look ahead to 2009 and a great lineup of REEF travel opportunities. Our partners at Caradonna Dive Adventure have helped us put together an exciting Field Survey schedule, including St. Croix, Bermuda (with Ned and Anna DeLoach), and Grenada on the Peter Hughes Winddancer (with Paul Humann). These week-long projects are led by experts in fish identification and include great diving, learning, and camaraderie with like-minded divers and snorkelers. Your non-diving companions are welcome on all of the land-based projects. There will also be several Lionfish Research Project expeditions, which allow participants to get first hand experience in this exploding invasive species issue. Be sure to check out all of these trips, posted online at http://www.reef.org/fieldsurveys/schedule. And remember that it's not just on REEF Trips that you can Make Dives That Count! You are encouraged to conduct surveys during your personal dive vacations farther afield and on local weekend dives in your own backyard. Be sure to order survey materials through the REEF Online Store before you leave and check out what species you are likely to see with the Geographic Summary Reports. And while you are waiting for your tank to be filled, it's fun to tell the folks at the dive shop what you are doing. Being a REEF ambassador helps spread the word about the Volunteer Survey Project and the value that fishwatching adds to your experience in the water. We hope that you will join us in making dives that count in 2009. We are kicking off the year with a Field Survey to St. Lucia led by new REEF Executive Director, Lisa Mitchell. To find out more or to book your space, please contact our dedicated travel specialist at 877-295-7333 (REEF), REEF@caradonna.com. And be sure to download our 2009 Trip Flyer!
Don't Just Blow Bubbles This Summer! Participate in the 18th Great Annual Fish Count. An exciting lineup of free identification seminars and survey dives are being organized around the country by REEF partners. Check out the GAFC Website for more details and to find out how to organize your own GAFC event. And be sure to watch the GAFC calendar of events to see what's being planned in your area.

A Big Win-Win: Have a Great Dive Trip and Support REEF. There are still some spaces left on 2009 REEF Field Survey Trips. Still to come in 2009 are REEF Field Survey trips to Key Largo with Ned and Anna DeLoach, Bermuda (again with Ned and Anna), Curacao and Cozumel.
Coming Soon -- Online Data Entry 2.0. An updated version of our Online Data Entry interface will be debuted in a few weeks. This version incorporates many of the suggestions that have been submitted over the years by our members, as well as the capability to submit surveys from the Northeast (Virginia - Newfoundland) and the Tropical Eastern Pacific (Baja - Galapagos Islands). We hope that this will facilitate an increase in surveying in these important regions. To log your data online, visit http://www.reef.org/dataentry/login.php.
Once again, REEF participated in the dive industry show, DEMA. We showed off all of the cool REEF gear, including our new lionfish t-shirts, which were a hit, as well as all of the REEF survey essentials. We also spoke with many dive instructors who were looking for new types of classes to teach. The REEF Fish ID curricula certainly fit the bill. A lot of networking was done and new friends made. And lots of people signed up for a free REEF membership. Thanks to generous sponsorship by Sherwood Scuba, we were able to host visitors and spread the word about REEF in a large double booth. As always, we couldn’t have done it without the help of several REEF volunteers. A big thank you goes to Jim and Mary Jo Davis, Robyn Churchill, Tom and Kay Wells, Lureen Ferretti, Deb Deavers, Beth Olsen, Andy Dehart and Park Chapman for all of their help at the REEF booth. Paul Humann and Anna DeLoach also spent a considerable time in the booth, to the delight of the dive community that happened to pass by! All in all, a truly enjoyable experience!
