To all our members who donated to the Winter Fundraising Campaign, thank you! REEF depends heavily on individual donors to support our critical marine conservation programs. Together we raised over $97,000 to ensure REEF can continue:
• Expanding and building upon our Volunteer Fish Survey Project, including the recent addition of invertebrate and algae monitoring in our Northeast region. With this new program, all temperate REEF regions now have an invertebrate/algae component. For more information, click here.
• Protecting and monitoring Nassau Grouper in the Cayman Islands as well as educating the public about the importance of this iconic species. Our team just came back from another successful trip documenting their annual spawning aggregation. For more information, click here.
• Organizing research, training, and removal tactics to battle the lionfish invasion on the East Coast and in the Caribbean. REEF’s recent research shows that strategic local efforts can control lionfish populations and help native fish communities recover. For more information, click here.
In addition to supporting these programs, donations raised by the Winter Fundraising campaign help REEF with the minimal costs required to manage operations. We ensure that every dollar spent is maximized so our projects make a difference for marine conservation around the world.
REEF’s recent Field Survey Trip to Belize was wonderful in many ways, but two events were of particular scientific interest. First, everybody’s favorite, the Sharpnose Pufferfish were spawning so there were literally hundreds seen on every single dive. More importantly, trip leader Jonathan Lavan got a photo of the rarely seen Glover’s Reef Toadfish (Vladichthys gloverensis) down in a sponge. It was thought to only live on Glover’s Reef, Belize, but this animal was photographed on an adjacent reef in Turneffe Atoll so perhaps a common name change is in order. Additionally, Jonathan's photograph is thought to be the only existing shot of the fish in its natural habitat. Great find, Jonathan!
We are excited to introduce Ellie Splain, who recently joined REEF staff at headquarters in Key Largo, FL. Ellie will serve as REEF's Education Program Manager. Ellie is no stranger to REEF, as she was a REEF Marine Conservation Intern in the summer of 2013. From a small rural town in Illinois, Ellie attended the University of Illinois Urbana-Champaign, where she earned a Bachelor of Science in FIsh and Wildlife Conservation. Despite growing up landlocked, Ellie has always been drawn to the ocean (and the good weather of South Florida doesn't hurt!). In addition to the REEF internship, during her undergraduate time, she spent time living in the Turks and Caicos Islands and assisted in REEF lionfish research in the Bahamas. After graduation, she moved back to the Florida Keys, where she earned her dive master rating and worked as a field instructor for Marine Resources Development Foundation. Ellie brings with her experience teaching marine ecology and conservation programs in both a classroom and field setting. Her primary focus at REEF will be education, outreach, and capacity building within the REEF Explorers Program, an informal education program offered to visiting groups of all ages. A big fish welcome to Ellie!
REEF Field Survey 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 ocean enthusiasts. There are still a few spaces remaining on 2015 trips to St. Lucia and Catalina, and we have an exciting lineup of destinations planned for 2016. We hope you will join us. REEF staff, board members, and other marine life experts lead the trips, and each features daily classroom seminars and a full diving schedule. Visit www.REEF.org/trips to see the complete schedule, package details, trip leader bios, and more. To find out more or to book your space, contact us at trips@REEF.org or call 305-588-5869. Book early - REEF trips often sell out! Also, keep an eye on the REEF Trips webpage because we will be adding a few more trips to the 2016 schedule (and beyond) in the coming months.
A new publication in the scientific journal, Coral Reefs, evaluates population genetics of spawning aggregations and the role of juvenile recruitment, from both local and external sources, in sustaining and increasing local aggregations. The study included information from REEF's Grouper Moon Project in the Cayman Islands.
Like many places throughout the Caribbean, Nassau Grouper spawning aggregations in the US Virgin Islands were overfished until their disappearance in the 1970s and 1980s. In the early 2000s, however, Nassau Grouper were found gathering at Grammanik Bank, USVI, a mesophotic coral reef adjacent to one of the extinct aggregation sites, and regulatory protective measures were implemented to protect this fledgling aggregation. The authors of this study addressed two objectives: 1) which factors (local vs. external recruitment) are important in shaping recovery of the USVI spawning aggregations, and 2) the impact of severe past overfishing on the genetic structure of the Gremmanik Bank aggregation. For this second objective, REEF Grouper Moon Project scientists provided genetic samples from individual Nassau Grouper taken from the Little Cayman spawning aggregation, a much larger and less impacted aggregation.
No population structure was detected between the USVI and Cayman spawning aggregations. Additionally, the USVI spawning population showed signs of a genetic bottleneck, typical of greatly reduced populations. These collective results suggest that external recruitment is an important driver of the USVI spawning aggregation recovery. These findings also provide a baseline for future genetic monitoring of the spawning aggregations. The paper, titled "The ups and downs of coral reef fishes: the genetic characteristics of a formerly severely overfished but currently recovering Nassau grouper fish spawning aggregation", was published earlier this month in the March 2016 issue of Coral Reefs. Grouper Moon scientist, Dr. Brice Semmens, was a co-author on the paper.

The highly-anticipated sequel to Disney and Pixar’s “Finding Nemo”, “Finding Dory” opened in theaters in June, and was recently announced to be the highest-grossing animated film of all time. The titular character, Dory, is a Palette Surgeonfish (Paracanthurus hepatic), who spends the film searching for her family. Native to the tropical waters of the Western Pacific Ocean (REEF’s Central Indo-Pacific and South Pacific regions), these bright blue, reef-dwelling, algae-eating fish are also referred to as Pacific Blue Tangs, Hippo Tangs, or Regal Tangs. In addition to the film’s endearing characters and entertainment value, the release of “Finding Dory” carries the potential for an increased demand for Palette Surgeonfish in home aquariums, as well as the message that marine fish should be released into the wild.
Marine biologists worry that the release of “Finding Dory” could cause an increased demand for Palette Surgeonfish, threatening wild populations as well as coral reef habitats. National Geographic estimates that following the release of “Finding Nemo” in 2003, the demand for Clown Anenomefish (Amphiprion percula) like Nemo, more than tripled. Anenomefish are able to be aquacultured, or bred in captivity. Until recently, Palette Surgeonfish had never successfully been captive-bred, however, researchers at the University of Florida Tropical Aquaculture Laboratory recently announced that for the first time they have successfully raised the Palette Surgeonfish in captivity. This conservation breakthrough means that aquarists may soon have a source for Palette Surgeonfish that does not rely on fish removed from the wild. REEF encourages pet owners to educate themselves about fish ownership before buying a marine fish, including specifics on living requirements such as tank size, and whether the fish was bred in captivity or caught in the wild.
In addition, pet owners should have a plan in place in case they are ever unable to care for their fish. In “Finding Dory”, we learn that Dory was born and raised in a facility on the California coast, but eventually ended up in the wild. Releasing non-native marine fish into the ocean from home aquariums, while well-intentioned, can create severe problems for marine ecosystems. One threat includes the spread of invasive species, like the Indo-Pacific Lionfish, which has caused dramatic impacts since their initial introduction in the 1980’s. Non-native fish may also carry diseases and parasites that can have harmful impacts on native fish species.
In 2015, REEF launched the “Don’t Release Me” campaign to educate pet owners about responsible pet ownership, teach the public about the effects of releasing non-native pet species into the wild, and work cooperatively with other organizations to promote alternatives to pet release and stop the spread of invasive species. To learn more about Don’t Release Me and responsible pet ownership, visit www.dontreleaseme.org.
Did you know? Our Fishinar program has been going strong now for 6 years! In that time, we've put on over 120 Fishinars and recorded most of them for later viewing as a benefit of REEF membership. Our typical Fishinar lasts about an hour. Check out our Fishinar archives and you might find something you like!
And we have another great year planned in 2017. In January, our focus will be on Lionfish. We'll have an online Do It Yourself Lionfish jewelry "how to" session on January 24th, along with a Lionfish update from expert scientist Dr. Stephanie Green on January 18th. If you're interested in Lionfish, you won't want to miss these! Visit the Fishinar page for all the details and links to register.
In the first few weeks of July we have started receiving reports of several Manta ray sightings at French Reef, near Key Largo, Florida. Mantas are found in the temperate, tropical, and sub tropical waters world wide. However, sightings in Florida waters are uncommon. Some observers saw the mantas swimming in large vertical loops, leading them to think that these animals were coming into the shallow reefs to feed on coral spawn.
Mantas inhabit near-shore and pelagic waters, and can grow up to ~14ft in width. They are primarily filter feeders, using large cephalic fins located on the head to help 'funnel' plankton into their mouths.
So, if your diving in the Florida Keys keep an eye out for one of these magnificent animals swimming by - and be sure to record it on your survey!
REEF once again participated in the Perigee Environmental's yearly evaluation of the coral ecosystems along the eastern coast of Andros, Bahamas in cooperation with the Atlantic Undersea Test and Evaluation Center (AUTEC). Using the newest Atlantic and Gulf Rapid Reef Assessment (AGRRA) surveying protocol, scientists gathered coral, benthic and fish data during the first 2 weeks of October. The data gathered will complement the existing 30 year data that demonstrates AUTEC's continuing efforts to preserve coral reefs around their facilities and military training ranges. Judy Lang, coral ecology expert, and Chris Moses, University of Southern Florida graduate student, were in charge of gathering the coral data. Brooke Gintert was conducting her Ph.D. work for the University of Miami and assisting with the benthic data collection. One of the REEF founders, Ken Marks and REEF intern Catherine Whitaker were responsible for the fish counting.
AUTEC has been actively monitoring and protecting the coral reef near shore environment since the establishment of the facilities in the 1960s. For the last six years, AUTEC has used the Atlantic and Gulf Rapid Reef Assessment surveying protocol, which is a method that compares the complex relationship among corals, fish and algae and provides a quantitative scale on the health of a reef's ecosystem by comparing the survey results in terms of a regional comparison. In this case, it is also being used to track temporal changes to 35 reef sites around central Andros. Point-count data and general coral data were collected to estimate coral condition and algal cover. Fish variety, abundance, and size was estimated by transects and the rover diver method.
For more information concerning this trip or AGRRA please contact Patricia Kramer of Perigee Environmental (email@example.com).
Top ten things I learned from my AGRRA trip:
10. Exhaustion is a state of mind and is not cured by more work, less sleep and diving. Food (especially Pringles and chocolate) helps though.
9. Golf carts should be used more often in the US.
8. Dinner waits for no man, so floor the pedal on that golf cart and RUN!
7. The floating pier at site 1 is cursed and sets off the rain whenever any member of the AGRRA trip steps on it to load or unload anything from the boat.
6. Snakes do not belong on planes, I mean, in camera cases but seem to like it there.
5. Crashing mountainous waves and cement-like waters are not conducive to good science or a pleasant dive.
4. Post-trip pep talks should always include sweets and beverages.
3. Rick makes the barren rock that is Site 4 look and feel like Club Med. Thanks Rick.
2. Things to do on your only day off (because of 30 knot winds and 6ft waves) include but are not limited to swimming against a raging outgoing tide at a blue hole, resting by snorkeling for 2 hours in an inland blue hole, spearing lionfish, dissecting said lionfish and having a horseshoe tournament.
1. Making new friends, doing science and experiencing a sense of accomplishment for conservation efforts... priceless.
My warmest wishes go out to our AUTEC liaisons, Tom Szlyk and Marc Ciminello for their invaluable assistance. I would also like to thank everyone who put in extra effort so that I could participate in this fantastic trip as well as anyone who taught me anything while I was on it. Thank you very much.
REEF Director of Science, Dr. Christy Pattengill-Semmens, joined a dozen other scientists in presenting the findings of monitoring the marine protected areas (MPAs) in the Channel Islands, California, earlier this month during a special session of the California Islands Symposium. The presentation highlighted the effect of reserves on common nearshore rocky reef fishes based on 10 years of REEF survey data. During this time, REEF volunteer divers have collected 1,595 visual fish surveys from 113 sites throughout the Channel Islands before and after state marine reserves were established in 2002. Using analysis methods developed to analyze volunteer bird watching data, collaborators Dr. Brice Semmens (NOAA NMFS) and Dr. Steve Katz (Channel Islands National Marine Sanctuary) developed a model to detect trends in fish densities. The analysis included 25 species of common rocky reef fishes, including targeted and non-targeted species. Rather than focusing on changes in the density of individual species, the analysis evaluated changes in multiple species to characterize responses of marine communities to protection from fishing in reserves. The analysis suggests that reserves are positively influencing fish population trajectories in both targeted and non-targeted species. On average, fish populations had ~20% higher growth rates inside reserves as compared to outside, although there was a high degree of variability across species. Dr. Pattengill-Semmens notes that this study is one of the first applications of Pacific region REEF data for use by marine resource agency officials to evaluate the effects of management actions. The results will ultimately be published and will join the many existing published studies of the utility of Tropical Western Atlantic REEF data. The cumulative impact of the data and results from the entire suite of monitoring programs being conducted around the Channel Islands will "help to inform future management of the region, aid in the implementation of the California Marine Life Protection Act in southern California, and contribute to our understanding of MPAs worldwide," said John Ugoretz, manager of the Marine Habitat Conservation Program for the California Department of Fish and Game.
