Ground-breaking invasive lionfish findings were featured in a paper published earlier this month in the scientific journal, Ecological Applications. The research was conducted as a collaboration between REEF, Oregon State University, Simon Fraser University, and the Cape Eleuthera Institute. The new study, conducted by Dr. Stephanie Green (OSU/REEF), Lad Akins (REEF), and others, confirms for the first time that controlling lionfish populations in the western Atlantic Ocean can pave the way for a recovery of native fish. Even if it's one speared fish at a time, data are showing that removals can be effective. And not every lionfish need be removed…the research findings document that reducing lionfish numbers by specified amounts will allow a rapid recovery of native fish biomass. Over 18 months, the biomass of native prey fishes increased an average 50-70% on reefs where lionfish numbers were suppressed below target levels predicted to cause prey depletion. On reefs where lionfish numbers remained higher than target levels, the biomass of prey fishes decreased by a further 50%. While complete eradication of lionfish from the Caribbean is not likely, groups are actively removing them from coastal areas (mostly via spear and net). This study is a first step in showing that strategic local efforts that suppress the invasion to low levels can help protect and recover native fish communities affected by lionfish.

"Did you ever have a fish experience that both excited and sadden you?"
That feeling recently happened to me at the dive site Kalli's Korner in Bonaire. My husband, Chile, and I were having a great day of diving with our friends Bryan and Phyllis McCauley in their boat, Pufferfish. Towards the end of our second dive that day, I noticed a pair of eyes peeping out of some coral rubble. As I watched suddenly a small eel darted out and raced few feet before hiding again. I was immediately intrigued and, using my rattle, got my buddy Phyllis' attention. Pointing out the location, we watched as once again the little conger eel slipped out of his cover and moved away. We slowly began to approach in hope of a better look. The process continued as we sought to identify him and he continued his trek. Each time we were able to get a bit closer and look for characteristics. Finally he seem comfortable enough to look at us, as we looked at him. Suddenly, a barred hamlet appeared above him and scooped him up. Imagine our shock and horror!!! Anger raced through my body and instinctually I reached for my dive knife and took off after that (blank blank) hamlet. The chase continued as the hamlet, with his full tummy, eluded me and viewed me as if to say 'why are you after me?' What was my plan I thought later? Well, I only know if I had caught the sucker, oops fish, he would have been disemboweled in the search for the little conger eel. The sound of laughter underwater reaches me. By this time, my dive buddy is in stitches as I sheepishly return. Later research found a margaintail conger that matched our descriptions.
Now as I continue my search for what I hope are his companions, I will be keeping a wary eye out for hamlets in the surrounding area. So that’s my fish tale and now for the question: Should you report to REEF a fish, found, identified but not longer living in the underwater world?
You can bet I did.
In an Enews article last May, I wrote about a collaborative effort between REEF and the Bahia Principe Resort in Akumal, Mexico. The Resort has been working with ReefAid ever since Hurricane Wilma (2005) did major damage to the reefs just in front of the resort, in an effort to study, protect, and restore these reefs. I was originally invited down to conduct a fish census on a large patch reef area off the beach from the property. The destruction to the inshore reef during Wilma was severe and ever since, Bahia Principe has worked with ReefAid to restore this patch reef area, establishing a protected zone around the most hard-hit areas. Part of Bahia Principe's long-term plan is to create a mitigation plan for future storms and to educate guests about ways they, too, can help protect the reefs. The Hotel Gran Bahia Principe is the Yucatan's largest resort complex, and there are currently 14 such resorts worldwide. After our last visit, ReefAid's Founder, Eric Engler and I co-wrote a protection and monitoring plan for the Resort that included periodic roving diver surey assessments, special signs and enforcement of no-swim areas, a coral nursery, and coral and invertebrate monitoring using another non-profit's methodology (ReefCheck).
On our last trip a few weeks ago, Eric and I received Reefcheck training over two days with Gabriela Georgina Nava Martinez, learning their survey methodology. Gaby also taught a Reefcheck class to the Bahia Principe dive staff , their onsite turtle rescue non-rpfit, Ecologica Bahia, and some of the Resort public relations personnel.. Bahia Principe is now a REEF Field Station and is close to becoming an educational center for REEF, teaching fish ID classes and training Resort guests in how to conduct fish surveys. Resort staff will soon routinely conduct Roving Diver Surveys of both the protected area and the offshore reefs frequented by multiple dive operators. Additionally, Reefcheck will train the dive staff to conduct 3-4 surveys per year at first to form a baseline assessment of the inshore protected reef. And finally, this year REEF is running a Field Survey to Bahia Principe (May 17-24, 2008). Please see our Field Survey page on our website at http://www.reef.org/fieldsurveys/schedule to learn more about our upcoming survey and how to participate.
The collaborative efforts between our three non-profits in Akumal represent a proactive involvement among multiple stakeholders to protect a critical resource, one that is very susceptible to damage from development and excessive tourist pressures. The ultimate goal of this synergistic, cooperative effort is to protect a large inshore reef area (see images) and improve the reef integrity with the addition of well-placed coral recruitment modules. To be candid, much of the Mexican Riviera is slated to be developed by an increasing number of resorts, most with requisite golf courses. And there are other environmental concerns in addition to the coral reefs offshore that form part of the Mesoamerican Barrier Reef such as all the cenotes (sink-holes) with their endemic terrestrial and aquatic species; the crucial watershed provided by the cenotes; loss of mangroves; the regional rainforest cover that is in jeopardy; excessive nutrient loading from all the resorts and urban development; not to mention the cultural world heritage significance of the Mayan communities and archaeological sites. However, the good news is that if Gran Bahia Principe is voluntarily willing to adopt special protection measures for their resort, these may serve as a "eco-friendly" archetype for other resorts in the region. This partnership building between organizations at the regional and international level bodes well for the adoption of some conservation plans for the area. Whether the proposed regional development can be slowed to a sustainable level is another story that time will tell.
If you are interested in learning more, here is an excellent summary article on some of the initiatives between resorts and non-profits working to preserve the Mesoamerican Barrier Reef from the NY Times last week. http://travel.nytimes.com/2007/06/24/travel/24headsup.html?emc=eta1
On Tuesday, February 26, REEF will host a community panel discussion to raise awareness about how volunteers contribute to scientific understanding of the Florida Keys environment. Rick Bonney of the Cornell Lab of Ornithology in Ithaca, New York will lead the discussion. Florida Keys-based citizen science practitioners will present on local projects and ways for volunteers to get involved. Topics include fish and bird surveying, native plants and coral restoration. A reception with the speakers will begin at 6:30, followed by presentations at 7 PM. This event will be held at the Key Largo Public Library and is free and open to the public.
A second panel discussion will be held on Wednesday, March 12 at the Florida Keys Eco-Discovery Center in Key West and will focus on citizen science projects in the lower Florida Keys. Speakers include:
Please join REEF staff and community partners for at least one of these educational evenings.
The 17th Great Annual Fish Count (GAFC) has arrived! GAFC is a month long event coordinated by REEF Field Stations that encourages volunteer divers and snorkelers to participate in recreational trips to raise awareness regarding marine habitats and trends in fish populations. REEF partners and Field Stations have organized everything from group dives and snorkels to photo contests, BBQs, and aquarium tours. This is a great opportunity to take a free REEF Fish ID class and connect with other individuals as well as groups, such as local dive operations and non-profit organizations, who are also interested in doing the same objectives. Numerous activities have been scheduled for the Pacific Coast, Hawaii, California, Washington, Florida, Maine, British Columbia, and many other regions- and still more are being added! Details for scheduled events can be found on the GAFC website. Each year GAFC events generate approximately 2,000 surveys in July alone and increase the interest and involvement of hundreds of surveyors worldwide. Participating in a GAFC event is a great way to make an active contribution to marine conservation and get involved with what REEF does year round- engage volunteer divers and snorkelers to collect critical, valid, and cost-effective data. We hope you get involved!
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.

Field Surveys – Eighteen REEF members joined Drs. Christy and Brice Semmens earlier this month on a Field Survey to the Sea of Cortez aboard the Rocio del Mar live-aboard. The team conducted over 300 surveys in 20 locations around the Midriff Islands, many of which were new to the REEF database. It was a great trip, with 130 species of fish found, beautiful topside scenery, and pods of sperm and pilot whales! Find out more about REEF Trips.
Lionfish Derby – The second of three lionfish round-ups in the Florida Keys was held last week off Marathon (FL). During this one-day event, several teams participated to collect this voracious predator off local reefs. The third derby is scheduled for November 13 in Key West.
