Following the most recent Indo-Pacific Lionfish expedition at Stuart Cove’s in Nassau, Bahamas, we kicked off the next phase of our critical research on this invasive species in Eleuthera. Supporters, Trish and David Ferguson, served as hosts for the week. Earlier this summer, REEF staff set up 11 study sites, tagging 30 fish on six different patch reef and clearing the other 5 sites of lionfish. This past week, I revisited those tagging sites and documented any movement of lionfish. We then following up with early morning, mid-day and evening activity observations to see what the fish were up to and when. The observations involved pre-sun up dives and 2-3 hour bottom times. With some very early and late dive times, the data collected is showing interesting patterns of low light activity.
After five days of intense data collecting at the Ferguson’s we headed down to Cape Eleuthera to meet with staff and students at the Island School and Cape Eleuthera Institute(CEI). The facility is completely self contained, producing their own electricity via solar and wind, their own biodiesel, raising cobia and tilapia in an aquaculture facility and even growing their own hydroponic vegetables. A very impressive operation and an incredible group of staff and students. We were able to conduct collecting and dissecting demonstrations for the coral research class and then do a packed house talk to all of the staff and students from TIS as well as a number from the local Deep Creek Middle School. There is strong interest in collaborating on future lionfish studies as well as incorporating fish surveys into the regular research curriculum at the IS and CEI. Look for future REEF projects to be scheduled here in 2009. Visit our Lionfish Research page for more information.
Last Friday, May 15th, America celebrated Endangered Species Day. While very few marine species have technically been declared as endangered, many of the critters that REEF volunteers see while conducting marine life surveys have experienced declines in recent years. REEF programs and data provide much needed information for scientists and resource agencies charged with evaluating the status of such species. A recent example is a National Marine Fisheries Service (NMFS) proposal to list 5 species of rockfish in the Puget Sound under the Endangered Species Act (ESA). The status review was just published on April 22 and REEF data were extensively used in the assessment. This example highlights the value of REEF data as a fisheries-independent data source; such information is critical for those species that are too rare to be targeted for harvest. A copy of the assessment is posted online.
The Nassau grouper, which is the focal species of REEF’s Grouper Moon Project, has been classified as endangered under the IUCN’s Red List. The Grouper Moon Project is a collaborative conservation program between REEF and the Cayman Islands Department of the Environment to study one of the last known large Nassau grouper spawning aggregations in the Caribbean. Grouper Moon Project lead scientist, Dr. Brice Semmens, will be presenting the ground-breaking findings of this research during a special one day session to be held in the Ocean Hall at the Smithsonian’s National Museum of Natural History this Wednesday, May 20th. "Beyond the Obituaries: Success Stories in Ocean Conservation" will feature some of the good news coming out of work being conducted in the oceans. Brice’s talk, along with all of the success stories, will be webcast online. The Grouper Moon talk is scheduled in the Coral Reef session, which is from 2-3:25.

Long-time REEF supporters, Les and Keri Wilk of ReefNet, recently discovered and photographed a distinctively marked population of the Greenbanded Goby, Elacatinus multifasciatus, on the island of Utila, Honduras. The population was distinguished by a prominent red stripe across the cheek that is not found on other populations of Greenbanded Gobies, as well as more numerous green bars on the body. The Wilks contacted Dr. Benjamin Victor (coralreeffish.com), a reef fish taxonomic expert, who conducted a regional genetic comparison of Greenbanded Gobies to evaluate hidden diversity within this colorful reef fish. As part of the study, the REEF database was used to document the current geographic range of the species. Dr. Victor's results identified the unique looking fish to be a separate species that is now called the Redcheek Goby (E. rubrigenis). He also discovered that, based on genetic results, Greenbanded Goby along coastal Panama, despite looking just like others in the species complex (i.e. a cryptic species, distinguished mainly by differing DNA sequences), are a distinct species that will now be called Panamanian Greenbanded Goby (E. panamensis). The study was published last month in the Journal of the Ocean Science Foundation.
The new species, the Redcheek Goby, replaces the Greenbanded Goby on the island of Utila and has not been sighted at any other location, potentially one of the smallest ranges reported for a Caribbean reef fish. With few exceptions, coral reef fishes have pelagic larvae that spend weeks to months developing in off-reef waters. As a result of this high dispersal ability, most Western Atlantic reef fish species have geographic ranges throughout the Caribbean Sea and adjacent areas. Endemic marine species (those only found in a given region or location and nowhere else in the world) are generally uncommon in the western Atlantic region. Furthermore, many of these widespread species show little, if any, variation in their genetic patterns between areas, particularly within the bounds of the Caribbean Sea with its many stepping-stone islands. Nevertheless, some groups of fishes, presumably those with more-restricted larval dispersal and strong local selection, show interesting patterns of endemism, genetic structure, and cryptic speciation within the region, for example among the Elacatinus cleaning gobies (e.g. Sharknose, Cleaning, Neon, Yellowline, etc.). Those reef fish taxa that contain cryptic species can provide valuable insights into the processes of speciation and the biogeographic history of the region, but also seriously challenge the traditional species concept. The results of Benjamin Victor's study highlight these challenges.
REEF is proud to be able to contribute to scientific studies such as this one. We are also thrilled that fishwatching by amateur non-scientists like our Fish Survey Project volunteers has been elevated beyond just a hobby, and is increasing the state of knowledge about reef fish diversity.

REEF is proud to partner with over 130 dive shops, dive clubs, individuals and other organizations as REEF Field Stations.
This month we feature Naknek Charters and Diving, based in Friday Harbor on San Juan Island in Washington State. They became a REEF Field Station in October of 2008. Owners Kurt and Peggy Long first got involved with REEF about 10 years ago when they were on a liveaboard dive charter in the British Virgin Islands, and took an onboard REEF Fish ID class. Since then, Kurt has gone on to submit many surveys and has advanced up to REEF Level 5, and is now on the Pacific NW Advanced Assessment Team. One of the reasons that they became a Field Station was because they were very interested in educating divers and the public in general about the wonderful critters that live under the water. Peggy writes, “We live in a beautiful area with an abundance of wildlife. We want the public to realize that the beauty extends to the underwater world. This is America’s best year-round cold water diving destination - we have walls, current, fish life. In other words we have it all!”
So what Field Station activities have they chosen to put into action? “Our goal is to hold a REEF weekend at least twice a year. This involves a Saturday morning class with a two-tank boat dive in the afternoon. We also offer an optional two-tank dive on Sunday. This is a great way for divers to learn about fish ID and helps them put that knowledge into practice. We sell REEF slates in our shop and our boat is identified with REEF decals.” Peggy and Kurt have a 45' charter boat that can hold 14 divers and they run charters year round.
REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Jonathan Lavan (REEF member since 2004). Jonathan has conducted 195 REEF surveys in four REEF regions, and he is a member of the Advanced Assessment Team in the Tropical Western Atlantic. Here's what Jonathan had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
I got certified at age twenty in the cold waters of Maine. I dove there and in Florida for a number of years but then, like so many of us, life got in the way for several years. When I got back into diving I quickly realized that I really knew very little about what I was looking at. I started buying some ID books and eventually stumbled upon the Caribbean Fish ID Guide by Humann and DeLoach. Sometime after that I found the REEF website and saw that REEF had trips. My wife and I signed up for the Bahamas trip in ’04 with Paul Humann and after that I was hooked. I usually go on a couple REEF trips a year and any other trip I go on I always do REEF surveys whenever possible.
If you have been on a REEF Field Survey, where and what was your trip highlight?
Last April I went to Dominica with trip leader Heather George. On one dive I got a little separated from the group (as usual) as I was taking photos. I found a small cave and managed to hunker down to get a good look inside despite all my gear. Tucked way back in the cave I saw something quite small undulating like a piece of ribbon in the wind. It was a Black Brotula! Well I started shaking my rattle like crazy to try and get someone’s attention. Finally, Heather and another diver came over and after much gesturing and changing of places they both, finally saw it. I must say there was nothing more satisfying then when Heather looked around that last corner way back in the cave, saw the elusive fish and then I heard her say clearly through her regulator: “OOOooohh!”
What is your favorite fish or marine invertebrate?
I have many favorites but I have to say that I never get tired of watching or taking pictures of Secretary Blennies. They are so easy to personify with all their goofy expressions and fussy behavior.
Do you have any surveying, fishwatching, or identification tips for REEF members?
As a photographer and surveyor, the key (as many know) is to go as slowly as possible. Let the divemaster race on ahead or make it very clear to them that you are going to be going “SLOOOW”. Not looking under that last ledge could be the difference between a great dive and really great dive.
REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
Our outstanding Field Station this month is Aqua Safari in Cozumel. Aqua Safari has supported REEF since 2001. At that time, long-time REEF member and Cozumel local, Sheryl Shea, took the lead in promoting the Fish Survey program through teaching fish ID to both Aqua Safari staff and customers. That year, Aqua Safari hosted the first Cozumel Field Survey trip, with REEF surveyors and marine park staff submitting over 200 surveys in just a week! Today, REEF's database holds data for over 400 species and over 6,000 surveys from Cozumel. Aqua Safari currently offers several fish ID courses to the general public: A "dry" introduction to Fish ID for snorkelers and divers; the REEF Level 2 course; and Advanced Fishes. There are plans to add a course geared to the interests of underwater photographers and an in-water snorkeling course with surveying. The Level 3 and advanced-level surveyor exams are offered annually during REEF Week. The shop stocks REEF books -- including a reference set for its customers' use after diving -- and survey materials. And they continue to host an annual REEF Field Survey trip each December (see www.REEF.org/trips). Aqua Safari warmly welcomes REEF members whom, the staff says, are generally excellent and aware divers who never fail to educate others on their boats. Aqua Safari has been in operation since 1966, pioneering sport diving in Cozumel and serving the island as an advocate for conservation of its marine environment. During the 1990's, owner Bill Horn worked toward the establishment of Cozumel's marine park and has maintained his vigilance regarding park policies and use. Thank you, Aqua Safari!
Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:
-A researcher from Florida International University is using REEF data from the Florida Keys to study changes in trophic interactions as a result of changes in top level predator communities in no-take reserves.
-REEF is working with staff from the Pew Environment Group and Southeast NOAA Fisheries to provide data that will facilitate the evaluation of Warsaw Grouper and Speckled Hind populations in the South Atlantic Ocean.
REEF is excited to announce the release of Invasive Lionfish: A Guide to Control and Management. Available as an e-book to view and/or download (formatted for desktop and mobile devices), this extensive manual was created to aid coastal managers and field workers in effectively managing the invasive lionfish problem. This best practices manual consists of chapters on control strategies, outreach and education plans, research, monitoring, legal considerations, and ideas for acquiring resources and vital partnerships from around the region. Invasive lionfish are a major ecological disaster causing wide-reaching negative impacts throughout the western Atlantic, Caribbean and Gulf of Mexico. By utilizing examples provided in this guide, researchers and managers throughout the region will be well equipped to address the lionfish invasion.
This work would not have been possible without the collaborative efforts of NOAA, REEF, ICRI, the United Nations Environment Programme, Caribbean Environment Programme, SPAWRAC, and the 40+ participants of the 2010 Caribbean Regional Lionfish Workshop. This manual will be the first book in the new GCFI Special Publication Series. Authors include James Morris (NOAA), Dayne Buddo (University of the West Indies, Jamaica), Stephanie Green (Simon Frasier University), Ricardo Lozano (CONANP, Mexico), and Lad Akins (REEF).
We are excited to announce the 2013 Summer Lionfish Derby Series! Five years ago, REEF began hosting lionfish derbies throughout Florida and the Caribbean to address the lionfish invasion. A lionfish derby is a single day team competition to collect as many lionfish as possible. Teams collect lionfish using nets or spears while SCUBA diving or free diving, and prizes are awarded to the teams with the most lionfish, biggest lionfish, and smallest lionfish caught. Not only do these events reduce lionfish populations, but they also increase education and awareness, provide samples for research, train divers in safe removal techniques, and help develop the market for lionfish as a food fish. To register or learn more, please visit www.REEF.org/lionfish/derbies. 2013 Derby dates and locations are: June 22 - Green Turtle Cay Bahamas; July 27 - Fort Lauderdale, FL; August 17 - Palm Beach, FL; September 14 - Key Largo, FL.
