REEF Surveyors Find Rare Fish on Belize Field Survey

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!

REEF Welcomes New Education Program Manager

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!

Taking a Dive Trip with REEF

Putting It To Work: New Study Looks at Spawning Aggregation Population Genetics

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.

Putting It To Work: New Publication Out of the Grouper Moon Project

A new publication in the scientific journal Coral Reefs was recently issued based on science conducted as part of REEF's Grouper Moon Project. The paper, titled "Hydroacoustics for the discovery and quantification of Nassau grouper (Epinephelus stratus) spawning aggregations", summarizes results from work conducted during the 2014 Grouper Moon Project field season in the Cayman Islands. Led by Jack Egerton from Bangor University in the UK, the research focused on the use of hydroacoustic technology as a means to monitor the status and ecology of fish spawning aggregations. Egerton was assisted by Grouper Moon scientists, Dr. Brice Semmens and Dr. Scott Heppell, as well as Grouper Moon collaborators from the Cayman Islands Department of Environment. Using a split-beam echo sounder, data were used to visualize and estimate fish abundance and biomass at three Nassau Grouper spawning aggregations in the Cayman Islands. The estimates were compared with diver-collected data. Additionally, the technology was used to examine fish aggregation locations in relation to protected zones.

Patterns in the acoustic abundance matched that observed by the visual estimates reported by our Grouper Moon diver teams - total numbers found at the Little Cayman aggregation were significanly higher than the depeleted aggregations found on Grand Cayman and Cayman Brac. 

Spawning aggregation location examined with reference to seasonal marine protected areas (Designated Grouper Spawning Areas) showed that the aggregations were partially outside these areas at Grand Cayman and very close to the boundary at Cayman Brac. The aggregation on Little Cayman appears to be contained within the protected zone (at least in 2014). However, we know from other Grouper Moon Project data that the fish spend a lot of time traveling in and out of the zone during the day. Additionally, in 2015, the aggregation on Little Cayman shifted a significant distance to the north of the historical location and partially out of the protected zone. The results of this study show the importance of making use of many different approaches for monitoring and aggregations in order to most effectively inform future management of aggregating fish species.

REEF Attends Vandenberg Event in Norfolk, VA

This past Columbus Day, I attended a special event in Norfolk, Virginia, where the ex-USAFS Vandenberg is in its final preparatory stages for deployment next spring, 6 miles off the coast of Key West. REEF will monitor the Vandenberg over the next 5 years in a similar monitoring and assessment project to the just completed 5-year Spiegel Grove assessment in Key Largo. The sinking of the Vandenberg is expected to add millions of dollars in diving/tourist related revenue to Monroe County. The hope is that the Vandenberg will not only add tourist revenue but also will reduce the diving pressure on the natural reefs in the area, “loving our reefs to death.”

REEF’s role will be assessing the biological impact the Vandenberg has on the fish community in the vicinity of this new addition. We fully anticipate that the Vandenberg will add to the fish species richness of the area as fish pass through and eventually settle onto the site as residents; provide protected areas for protected IUCN listed species such as Goliath and Nassau groupers; and increase the fish biomass in the area as the fishes on the Vandenberg mature and then reproduce, in effect seeding the surrounding reefs. The Vandenberg will be deployed in approximately 140-ft of water, close to 540’ in length (just 30-ft longer than the Spiegel), but weighs almost 3 times as much as the Spiegel Grove at around 15,000 tons! REEFMAKERS™ is currently reducing the height of the ship and taking some of the towers and satellite dishes and strategically placing these structures onto the deck, adding a lot of complex structure that should be very attractive habitats for fishes. The aim is to sink the Vandenberg in less than 3 minutes, adding a dramatic crescendo onto a multi-year project in the making!

We are currently working out the final monitoring plan but we anticipate a pre-deployment event in the spring of 2008, followed by 3 additional monitoring events next year using our Advanced Assessment Team members. Similar to the Spiegel, REEF will monitor not only the Vandenberg itself but 7 surrounding reference sites over several days per event. REEF’s data analysis from our 5-year Spiegel project, once complete, will assist us in the Vandenberg project expectations. The sinking of the Vandenberg has been in the planning stages for several years and REEF will be working directly or indirectly with several partners on this project including:

REEFMAKERS™ in New Jersey and Artificial Reefs of the Keys (ARK) based in Key West will be responsible for sinking the Vandenberg, along with the direct support of the Florida Fish and Wildlife Conservation Commission. REEF is excited to be a part of this project with all its intrinsic biological, socioeconomic and educational value.

Thanks to funding from The Russell Family Foundation (TRFF) and a lot of hard work and coordination by regional REEF instructor, Janna Nichols, the Pacific Northwest is REEF's fastest growing region. The goals of the TRFF project were to enlist new divers into the REEF Volunteer Survey Project and provide incentive for existing surveyors to stay involved and increase their experience level. Between 1998 when REEF was launched in the Pacific Northwest and the beginning of the training program funded by TRFF, 4,101 surveys had been conducted in Washington State. During the 12 months of the project, the number of surveys increased an incredible 25% as a result of the funded project activities. 

Eighty-three volunteers conducted these 1,065 surveys; 40 of the surveyors were new to the REEF Volunteer Survey Project (a total of 398 volunteers have conducted surveys in Washington since 1998). Many of these new volunteers have already become quite active and as a result of the project, 98 REEF surveyors advanced at least one level in their survey experience rating (including 10 new Expert rated surveyors!). This surge of involved and invested volunteers is invaluable to REEF capacity building efforts in the Pacific Northwest region. Another outcome of the TRFF project was the development of an advanced fish identification course for the Pacific Northwest. The course was debuted to a crowd of sixty divers at the Seattle Aquarium in May and will be available through the REEF online store later this month.

The TRFF project highlighted the importance of providing continued education for our members and opportunities for organized surveying. While the TRFF project has come to an end, REEF recently secured a grant from the Seattle Biotech Legacy Foundation (SBLF) to continue these training opportunities. The SBLF project is also supporting REEF Director of Science, Dr. Christy Pattengill-Semmens, to attend the annual Ecological Society of America conference later this summer to present a talk on the importance of citizen science for conservation and management applications.
