We are pleased to share the publication of two new scientific papers that utilize data collected by REEF volunteers in the Monterey Peninsula area of California. Co-authored by REEF Pacific Advanced Assessment Team (AAT) member, John Wolfe, and REEF Director of Science, Dr. Christy Pattengill-Semmens, the companion papers were published earlier this summer in the journal CalCOFI Reports. The first paper, Estimating Fish Populations From REEF Citizen Science Volunteer Diver Order-of-Magnitude Surveys, describes several mathematical models to convert order-of-magnitude count data (the type of data collected during REEF Roving Diver Technique surveys) to a numeric mean. The second paper, Fish Population Fluctuation Estimates Based on Fifteen Years of REEF Volunteer Diver Data For the Monterey Peninsula, California, used the best-performing model technique to evaluate population trends in rocky reef fish species along the Monterey Peninsula. Over 3,000 REEF surveys have been conducted in this region over the last 15 years. Many of these data were collected during an annual project within the Monterey Bay National Marine Sanctuary conducted with the help of members of the Pacific AAT. Changes in relative density over time were reported for 18 fish species, including several fisheries-targeted species. Strong concordance was also found between REEF data and those collected by Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), a consortium of academic institutions. Results showed that data collected by REEF have great potential to augment and strengthen professional research data and serve as a valuable baseline to evaluate marine reserves. Both of these papers can be found on the REEF Publications page here - www.REEF.org/db/publications (as well as downloadable from the CalCOFI Reports webpage).

Eggs were collected during spawning and then reared in a lab for a few days.

REEF scientists and volunteers just wrapped up another season of the Grouper Moon Project, a collaborative research effort with the Cayman Islands Department of the Environment (CIDOE). Our research focuses on Little Cayman, which has one of the largest (and one of just a few) known spawning aggregations of Nassau Grouper in the Caribbean. Over 4,000 grouper amass in one location for 7-10 days following winter full moons. Our team went to Little Cayman around full moons in both January and February this year (both because it was considered a “split year”, meaning the full moon dates were right on the line of predicting which month would be the strong spawning month). February turned out to be the big month, and spawning was seen over 3 nights starting 3 nights after full moon. Watch a short video montage of the aggregation and spawning action here - http://youtu.be/GwKVzPLgmbo

Since 2002, REEF and our partners at CIDOE, Scripps Institution of Oceanography, and Oregon State University have used a variety of research techniques from diver surveys to state-of-the-art technology to study this amazing natural phenomenon. The research has yielded ground-breaking results that have led to improved conservation for Nassau Grouper in the Cayman Islands. This year, we tested out some new techniques for collecting and rearing fertilized eggs (in the montage video you will see a diver swimming through a spawn cloud with a plastic bag). After collecting Nassau grouper eggs during the two nights of peak spawning, Scripps scientists and REEF Grouper Moon Project volunteers cultured the eggs at the Central Caribbean Marine Institute on Little Cayman. After one night, a subset of eggs were preserved for research on fertilization rates. After two nights, the eggs had hatched, and researchers were surprised to find larval Nassau swimming around the tank the next morning. Check out this video of larval Nassau grouper under the microscope - http://youtu.be/0Vph6LzH9IE

In addition to the research, REEF also is leading the charge on an educational program surrounding Nassau Grouper and spawning aggregations. Thanks to support from Disney Worldwide Conservation Fund, we have created an exciting K-12 education curriculum rooted in the link between healthy reef communities (including humans) and healthy spawning aggregations. See last month's REEF newsletter for more about the Grouper Education Program.

Want to learn more about the Grouper Moon Project? Lead scientist, Dr. Brice Semmens, recently gave a Perspectives in Ocean Science talk at Scripps Institution of Oceanography. The entire talk is online. Click here to watch! To see many more photos, videos, and stories from this year's work, check out the REEF Facebook page here.

Many Thanks! The Grouper Moon Project wouldn’t be possible without the dedication, passion, and financial support from many individuals, Cayman Island businesses, and foundations. It truly takes a village to pull off this conservation research project. In 2014, we especially appreciate the continued generous logistical support provided by Peter Hillenbrand, local lodging and dive operators Reef Divers & Little Cayman Beach Resort and the Southern Cross Club (especially Neil van Niekerk and the crew of the Lucky Devil for taking our team out in January), and Brac Reef Resort. Funding from the Disney Worldwide Conservation Fund supported field efforts and the Grouper Education Program. LIME Cayman Islands has provided support for the live-video feeds for the Grouper Education Project since 2012. Cayman Airways provided inter-island travel support. And the staff at Central Caribbean Marine Institute provided research space for the fertilized egg work. Thanks also to our scientists, volunteers, and partners who made this year's efforts possible - Adam, Alex, Brenda, Bradley, Croy, Guy, Hal, Ivan, James, Josh, Keith, Leslie, Laura, Lynn, Paul, Steve, and Todd. It's impossible to list everyone here - please visit the Grouper Moon page to see the full list - http://www.REEF.org//groupermoonproject.

St. Vincent Field Survey Breaks One-Week Species Record!

REEF_St-Vincent-group_l.jpg
The REEF St. Vincent Field Survey Team

To those who are in the know, St Vincent is considered the critter capital of the Caribbean. To those who watch fish, it is known that the rare is commonplace and that the fishwatching is unlike any other location in the Caribbean. REEF’s data from the June Field Survey supports those claims. With a team of 13 divers, the REEF group recorded an astounding 243 species, more than 65 of which were unlisted “write-ins” on the survey forms.

Diving with Bills Tewes at Dive St Vincent, long time REEF supporter and widely regarded “Caribbean Character”, the team split up on two boats and survey sites around the southwest end of the island. Long-time REEF expert Franklin Neal provided an extra special view from above and into shallow water as he snorkeled, while other team members spent hours on each dive exploring varied habitats and depths.

Special finds during the week would take an entire newsletter to list, but there were a few fish that stood out including the still undescribed Bluebar Jawfish on most sites, five frog fish on one dive, multiple black brotula, various pipefish commonly sighted and the largest spotfin gobies (10 inches?!) we’ve ever seen. The fish of the week may well have been the Golden Hamlet that Bill pointed out as his favorite fish and the species that adorns the cover of Reef Fish Identification.

The diving was bottom time unlimited and many dives exceeded two hours finishing in shallow water. Habitats were varied and visibility ranged from good to excellent on all of our dives. REEF is already planning our next Field Survey to dive St Vincent in August of 2008. The project will be led by Paul Humann and will be a must for any serious fishwatcher.

The recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the United States Geological Service (USGS), the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. As part of REEF’s Lionfish Research Program, over the last two years REEF has coordinated 12 research projects that have involved over 175 REEF volunteers. This research has generated a wealth of in-situ observations and over 1,000 lionfish specimens, which have led to great advances in the understanding of the biology and potential impacts of this most unwanted invader.

REEF’s most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement.  Findings included:

Lionfish continue to grow in size: Tagging data show growth rates exceeding 190mm/year, far larger than necessary to reach sexual maturity.

Site Fidelity: All 12 previously-tagged specimens that have been recaptured indicate strong site fidelity even after 6 months.

Prey: Lionfish continue to amaze us during stomach content studies. The recent effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. Lionfishare eating nearly anything that will fit into their mouths.

Reproduction: Lionfish reproduction occurs throughout the year – many gravid females and a small recently settled juveniles have been found.

REEF’s future fieldwork will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program.

    The USS Hoyt Vandenberg is the most recent ship to be placed as an artificial reef in the waters off Key West, Florida. The ship was sunk on May 27, 2009, but three weeks prior to the sinking the REEF team was in action conducting surveys of the sinking site and 7 other adjacent sites for comparison. The data will be used by the State of Florida to document fish recruitment onto the wreck and response of nearby reef sites to the new structure. In addition to regular REEF fish surveys, the team is also gathering important fish biomass data at two sites and recording any observations of non-native titan acorn barnacles, orange cup corals or non-native fish including lionfish.

    The pre-deployment surveys at the sinking site did not document any fish present at the sandy bottom site though one barracuda was seen swimming through the area shortly after. Combined data from the 7 reference sites documented 159 species including rare sightings of pugjaw wormfish and cherubfish (rare for the Keys). The summary of data can be found here.

    REEF will continue regular monitoring of the Vandenberg and reference sites through next summer, with a final report due by the end of 2010. A huge thank you to all of the REEF experts joining in on the effort including Rob McCall, Tracy Harris, Dave Grenda, Brenda Hitt, Jamie Giganti, Lisa Canty and Pat Zuloaga.
