Once again, it is that time of year when many of you are getting out on the water and conducting REEF Fish Surveys. I have put together a few bullet points based on my experiences surveying with members and answering questions on techniques and things to watch out for when filling out your data sheets. Here are a few tips:
- REEF Hats! Just Added to the REEF Store. Check them out and get yours today.
- The 2009 Field Survey Schedule has been updated with several new trips, including a second trip to Cozumel this December and Bermuda with Ned and Anna DeLoach in October 2009.
- REEF researchers and collaborators have been busy in the field this month on the Grouper Moon Project. Watch for an update in next month's REEF-in-Brief.
- REEF's Lionfish Research was featured on the National Geographic News earlier this week. This follows extensive coverage by the Associated Press earlier this month. Also this month, Anna DeLoach produced this 5 minute video for Scuba Diving Magazine that looks at the the recent lionfish population explosion, the reasons lionfish are the perfect invader, how they got to the wrong sea, what REEF is doing about it, and how divers can help. Watch this informative video here. Read more about this project in this recent press release.
REEF has been around for over 15 years and we felt it was time to give back to the community that has housed and supported us since REEF’s inception. So we came up with REEF Fish & Friends, a monthly meeting/seminar in Key Largo that gathers snorkelers, divers and armchair naturalists to learn more about fish and have some fun. Our first REEF Fish & Friends was held March 10 at the James E. Lockwood REEF Headquarters. Paul Humann, the opening night speaker, shared the history of REEF and highlighted milestones over the last decade and half.
Paul visited with guests and signed books and then spoke for about an hour. The room was packed and people were even standing in the hall to listen. As most of you know, Paul is the consummate story teller and we had some laughs, learned some new things about REEF and got to hear firsthand how the organization came to be.
REEF Fish & Friends will be 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. We are planning a line-up of interesting guest speakers as well as REEF staff in the coming months.
In conjunction with the lecture series, we will also be working with local dive operators to arrange a monthly REEF survey dive/snorkel trip. No experience necessary. REEF Fish & Friends is all about learning how to survey and teaching others – its fun, easy and you will reap immediate results – making a dive that counts.
Upcoming Fish & Friends -- On Tuesday April 14, Lad Akins, REEF’s Director of Special Projects and the recognized lionfish expert, will present Born in the Wrong Sea – a presentation about the invasion of the Pacific lionfish in Atlantic and Caribbean waters. He will present the latest information on sightings and the important marine conservation work that REEF is doing to manage this huge environmental problem.
Tuesday May 12, Lad will return to present Parrotfish and Wrasse. This will be a shortened version of the presentations that are done on REEF Field Surveys. Even if you think you know your Parrotfish and Wrasse come and listen as Lad presents ID techniques, habitat and behavior. These hermaphrodites are fascinating and are sure to provide fodder for an interesting presentation.
Keep an eye on our REEF Fish and Friends webpage (www.reef.org/fishandfriends) as we post info about presentations, trips, photos and more. So see you Tuesday April 14 at the James E Lockwood REEF House, MM 98.3 from 6 PM to 7:30 PM.
Our t-shirt may say, “It’s all about the fish”, but if you’ve been on a REEF trip, you know it’s about the people too. Diving with like-minded enthusiasts who share your interest in learning more about our underwater world is one of the best ways to spend your dive vacation! Our recent trip to Curacao was no exception – a great group of surveyors of all levels came together to share their knowledge, fish encounters, and a lot of fun. Experts Doug Harder and Kay Tidemann showed us some of the unusuals, including the delicate Pale Cardinalfish and a rare reverse-pattern Goldentail Moray. We even taught our divemaster Elric about some of the various phases of wrasses and parrotfish. At the end of the week, our sister team of Helen and Sally Davies both passed their Level 3 tests, and beginning surveyors Amy Kramer and Norm Valor are now officially at Level 2.
If you are interested in taking a “dive (trip) that counts” and making new friends, there is no better way than to join us on a REEF trip next year. Our diverse schedule has something for everyone, and some trips are already starting to fill up…only a few spots are left on the Belize Lionfish trip for example.

Congratulations to our newest Field Stations who have joined us since the start of 2010! These shops, charters, instructors and organizations can support REEF in many ways - offering classes, REEF survey opportunities, stocking survey supplies, etc. For more information and to check out who the other 173 REEF Field Stations are, go to the Field Station page on the REEF website.
REEF Field Surveys 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. The recent trip to Key Largo was no exception. REEF surveyors gathered in late August at Amoray Dive Resort for the Key Largo Field Survey and Coral Conservation trip. The trip was scheduled around the annual coral spawning that usually occurs in the Keys after the full moon of August. Amy Slate, owner of Amoray, organized a great week of activities, including presentations by Lauri MacLaughlin, from the Florida Keys National Marine Sanctuary (FKNMS) and Ken Nedimyer, founder of the Coral Restoration Foundation. A 3-minute highlite video is posted on YouTube here.
Ned DeLoach kicked off the week with presentations about fish behavior and an overview of Key Largo’s more famous fish species. Key Largo is known for its grunts so we started the week with back-to-back dives on the Benwood, where fish watchers can regularly observe eight species of grunts on a dive. The second dive was timed with the daily arrival of the parrotfish that bed down for the night in the nooks and crannies of the wreck. Hundreds of Blue, Midnight and Rainbow parrotfish arrive around sunset and spend about 15 minutes swooping around before they settle in to sleep. For veteran fish counters, this is a bonanza because it is extremely rare to be able to mark Abundant (over 100) for Midnight parrotfish!
Lauri MacLaughlin has amassed an extensive collection of spawning coral video and uses it to educate the public about the plight of coral reefs but also showcases Sanctuary programs that give hope for their future. After her presentation, our group joined Lauri and her team on the projected night for spawning staghorn and elkhorn coral. They placed tents over selected corals to capture gametes for research while we spent several hours watching for signs of gamete bundle formation in the polyps. Unfortunately none of the research groups stationed all over the Keys observed any spawning that evening.
To continue with our coral conservation theme, Ken Nedimyer joined us to tell us his inspiring story about how he made the transition from live rock farmer for the aquarium industry to coral farmer. Ken and his family turned a few small coral recruits that settled on his live rock into over 5,000 growing coral colonies. His organization has now successfully transplanted corals on a number of reefs in the Florida Keys Sanctuary. After Ken’s talk we load up the boat for a visit to his coral nursery and some hands-on work. There is no better way to understand the scope of what he has accomplished than to see it for ourselves and contribute to the cause by helping with some of busy work scrubbing algae and cementing coral fragments to concrete bases. Fish surveys in the coral nursery are usually productive and this time included a tiny jackknife fish and an Emerald parrotfish.
The week included a visit to REEF headquarters where staff and volunteers, Jane Bixby, Karla Hightshoe and Nancy Perez treated us to refreshments and a tour. Field Operations Coordinator Alecia Adamson gave her very informative presentation about REEF’s programs dealing with the invasive lionfish in the Tropical Western Atlantic.
Other highlights of the week included a dive with a very inquisitive Goliath grouper and a rare chance to survey the grass beds and mangroves on the Florida Bay side of Key Largo, where we added Sea Bream, Inshore lizardfish, and Banner and Frillfin gobies to our list. We ended the week with two dives at Snapper Ledge; a site that has received a lot of attention in the past few years by groups who are petitioning to have the area designated a Sanctuary Preservation Area to protect the thousands of fish that gather there. It was a fishwatcher’s dream, a fitting way to end the week.
If all of this sounds fun, we hope you will join us on a future Field Survey. The 2011 trip schedule is now posted online here -- http://www.reef.org/fieldsurveys/schedule
There are a few Field Survey trips in 2011 with spaces available. Please consider joining us in one of these great destinations – Maui, Roatan, and the Bahamas. 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 lead these trips, and each features daily classroom seminars and a full diving schedule.
Maui, Hawaii – April 16-22 - The package includes 4 days of diving on the dramatic reefs off Lanai and west Maui with Extended Horizons, who operates one of the friendliest and most experienced scuba charter boat in Lahaina. They offer up to 33% more bottom time than other Lanai dive boats and their interpretive naturalist staff make this operation a perfect fit for a REEF group. We will also do several shore dives around the island. And with all of the beautiful beaches and land-based activities, this is a great destination for non-diving friends and family. Led by Dr. Christy Pattengill-Semmens, REEF Director of Science.
Green Turtle Cay, Bahamas – June 12-18 – The package includes 7 nights at Green Turtle Club and 6 days of 2 tank boat dives at Brandal’s Dive Shop. In addition to conducting fish surveys, this trip will help document the establishment and consequences of invasive lionfish in REEF’s ongoing effort to minimize the Indo-Pacific predator’s impact on native fish populations, including dissections of specimens to document prey. Led by Lad Akins, REEF Director of Special Projects.
Roatan, Honduras – July 30-August 6 – The package includes 7 nights accommodations at Anthony’s Key Resort, all meals, 3 single tank boat dives per day (6 days), 2 single tank boat night dives, a day excursion to Maya Key, and airport transfers. REEF is conducting this project at the invitation of the Roatan Marine Park to survey in the protected areas of the park to evaluate how the reserves are working. Led by Alecia Adamson, REEF Field Operations Coordinator.

When you call the REEF office, you may be greeted with a new voice. Please join us in welcoming Martha Klitzkie as the new General Manager. After completing a Bachelor of Arts from Warren Wilson College, a passion for marine education led her to serve as the Education Director at the Pigeon Key Foundation in Marathon, Florida. She later went on to direct a larger marine education program based at Camp Ocean Pines, located on the central coast of California. During this time she also completed a Master of Arts in Educational Leadership and Administration from Argosy University. But a love for the Florida Keys and its coral reefs brought her back home to the sunshine state to join the REEF team. As the General Manager, Martha supervises a variety of activities necessary to the day-to-day operations at REEF. Welcome, Martha!
There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems. REEF Director of Special Projects, Lad Akins, is a co-author on a recently published paper evaluating these effects. The study was published in the scientific journal, PLoS ONE. Lead author, Stephanie Green, from Simon Fraser University (SFU), along with Akins and other co-authors Aleks Maljković (SFU), and Isabelle Côté (SFU), documented a dramatic 65% decline in 42 species of reef fish eaten by lionfish over a two year period. The study, conducted off New Providence Island in the Bahamas, used data collected during REEF's volunteer lionfish projects to track the explosion of the lionfish population over time, and reveals that lionfish biomass increased from 23% to nearly 40% of the predator biomass on the study sites between 2008 and 2010. This study represents the first documented direct impact of lionfish predation on native reef fishes and highlights the importance of control programs to minimize impacts. You can find a link to this and all published papers that have included REEF data on our Publications page.
New research using powerful genetic techniques and the REEF survey data have revealed two new species of hamlet in the Caribbean. The findings were recently published by scientist Ben Victor in the Journal of the Ocean Science Foundation. As our Caribbean surveyors know, hamlets are a group of colorful small sea basses that can sometimes cause ID confusion because of their myriad of colors and patterns. The varied color patterns in these small predators are thought to be a result of mimicry of other colorful but more innocuous herbivore species. There has been ongoing debate about which are actual species and which are simply just color variants or morphotypes. Ben's research revealed significant genetic differences among what seemed to simply be variations of the well-known Barred Hamlet. Ben stated that "the REEF database supplied valuable survey data indispensable to understanding ranges and abundances and unmatched in its comprehensive coverage".
The two new species are the Florida Barred Hamlet, Hypoplectrus floridae, and the Contoy Hamlet, H. ecosur. The typical Barred Hamlet (H. puella) that is found throughout the Caribbean will be updated in the REEF database to be called the Caribbean Barred Hamlet. Florida Barred Hamlet have been found in the eastern Gulf of Mexico and South Florida, and overlaps in range with the Caribbean Barred Hamlet in those areas. To date, the Contoy Hamlet has only been documented on Isla Contoy near the northern tip of the Yucatan peninsula and maybe Isla Mujeres. Florida Barred Hamlet are distinguished by a pair of symmetrical dark spots at the base of the caudal fin along with a break in the mid-body narrow bar. The Contoy Hamlet is distinguished by the same paid of dark spots at the base of the tail as well as a series of additional dark spots along the upper caudal peduncle and below the dorsal fin. A PDF of Ben's paper can be found online here, and it includes many pictures of the new species. Video of the Contoy Hamlet has been posted on Youtube.
REEF surveyors in the regions of the new species are encouraged to learn the differences and being reporting them as distinct species using the Unlisted Species section of the online data form.
