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.

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 are a regular reader of Making It Count, you may have already heard of these exciting discoveries. They are significant steps forward in marine conservation efforts, and it is only possible through donor support, citizen science, and the help of our members, that we uncovered:
From all of us at REEF, we sincerely thank all our donors who make this work possible! Please have a safe and fun-filled 4th of July!
On Saturday, July 14th, seventy members of the REEF Sustainers Club (annual donors of $1,000 or more), key partners and long-time REEF friends convened in Key Largo, Florida to celebrate fourteen years of REEF accomplishments over some diving and a sunset dinner. Paul Humann, Ned DeLoach and other Board, staff and Advisory Panel members were on hand to lead guests on some spectacular morning REEF survey dives while Amy Slate and her stand-up staff at the Amoray Dive Resort generously hosted the lodging and dinner party. “The event was just beautiful.” Said long-time REEF surveyor Elaine Morden, of Homestead, Florida. “It was great to connect with old REEF friends and see some new faces.”
The bi-annual Sustainers Event is a chance for REEF to bring together important members of the REEF family to thank them for their contributions and share successes of the organization over the years. This year, REEF was proud to recognize Linda Schillinger for achieving one of the highest REEF honors: admission into the Golden Hamlet club for those who have conducted 1,000 or more REEF surveys. We were also proud to recognize Key Largo resident and REEF office volunteer Audrey Smith for nearly ten years of regular service to the organization by quality-checking survey scanforms before they are uploaded to the REEF database. REEF was itself bestowed with an honor by Sanctuary Friends of the Florida Keys Director Glenn Patton: SFFFK generously gave a gift of support for the Great Annual Fish Count this year to help underwrite the costs of public outreach and education events.
By virtue of a Paul presentation and applause vote, the group answered the perennial question “What is the most beautiful fish in the Caribbean?” Out of thirty possibilities ranging from the spotfin hogfish to the fairy basslet, the spotted eagle ray won a narrow victory over close rivals the queen angelfish and queen triggerfish. Ned enthralled the group with fish behavior anecdotes from as far afield as Indonesia and gave updates on valuable REEF programs ranging from the Grouper Moon Project to the Exotics Species Sightings Project.
All agreed that the only thing hotter than the event itself was the Florida sun in July. With the heat index topping 100 degrees, no one needed a better excuse to indulge in a new REEF-inspired cocktail, the Indigo Hamlet, a unique and diversified alcoholic concoction for our wonderful sustainers to imbibe in while enjoying the sunset! Many thanks to all who made this a Sustainers Weekend to remember. See you at the next one . . .

Here are a few notes and news bits we'd like you to know about:
Four spots recently opened on our Turks and Caicos Field Survey aboard the Aggressor II, April 19-26, 2008. This is a wonderful opportunity for new and experienced REEF surveyors to spend a week diving in one of the jewels of the Caribbean. You can take advantage of our live-aboard accomodations and make up to 5 dives per day at all the best sites these islands have to offer.
There are quite a few expert surveyors on this trip, so if you're a beginning surveyor, you'll have plenty of mentorship and you could even work toward becoming an expert by the end of the week. For our experts, there are many cryptic species to challenge us on our surveys. We will have a number of REEF Fish ID classes and time to catch participants up on the many exciting upcoming REEF projects worldwide for 2008.
To reserve your spot - please call Joe Cavanaugh at 305-852-0030, ext. 3 or Tami Gardner at Travel for You, 1-888-363-3345, For more information about the trip, please visit our Field Survey page atField Survey page Hope you can join us!
In response to the growing threat of lionfish in the Atlantic and the need for coordinated planning, REEF, NOAA and the USGS are hosting a technical workshop on Non-native Marine Fish Introductions of South Florida in the Florida Keys June 18 and 19. The workshop, jointly funded through a recent Mote Marine Laboratory’s Protect Our Reefs grant, NOAA’s Exotic Species and National Marine Sanctuary Programs and the Gulf and Atlantic States Regional Panel on Aquatic Invasive Species,will bring together personnel from more than 18 different agencies and organizations. Plans for the workshop include presentations by State and Federal agencies, breakout groups and round table discussions that will focus on disseminating the most current information, and drafting a coordinated plan of early detection, notification, and rapid response.
Lionfish have been recorded in large numbers from North Carolina through the Bahamas and are rapidly expanding into the Caribbean. Fortunately, the fish have not yet shown up in the southeast Florida reef tract including Biscayne National Park, the Florida Keys National Marine Sanctuary and the Dry Tortugas National Park and Ecological Reserves. This planning workshop will endeavor to put in place mechanisms to help minimize lionfish impact in these treasured marine protected areas. While lionfish are the “poster fish” of invasive species, the protocols developed in this workshop will be widely applicable for sightings of other non-native marine fish as well, with the goal of preventing future invasions by other species.
REEF will continue to host training and planning workshops, as funding allows, to help downstream countries plan for the arrival of lionfish. Efforts to control populations and minimize impactswill be highlighted as research answers key questions and we are able to develop control methods. To find out more about REEF's Exotic Species Program, contact Lad Akins, Director of Special Projects.
