No, it's not a club of Shakespearean enthusiasts! Rather it's a club of citizen scientist superstars - those REEF members who have conducted 1,000+ surveys in the REEF Volunteer Fish Survey Project. The very first Golden Hamlet member was Linda Baker, achieving the status in 2005. Today, there are are sixteen members of the Golden Hamlet Club. We recently created a plaque, now hanging at REEF HQ in Key Largo, with the names of our honored volunteer surveyors -- Lad Akins, Linda Baker, Judie Clee, Janet Eyre, Dave Grenda, Doug Harder, Lillian Kenney, Peter Leahy, Rob McCall, Franklin Neal, Mike Phelan, Bruce Purdy, Linda Ridley, Dee Scarr, Linda Schillinger, and Sheryl Shea. Congratulations to you all. Thanks to their dedication, and those of the 14,000 other volunteers who have participated in the Survey Project since its inception in 1993, we have generated the largest marine fish sightings database in the world. Who's going to be the next Golden Hamlet surveyor?
It was a science lesson with a difference, broadcast live from beneath the waves with thousands of endangered fish in attendance. Earlier this month, Grouper Moon Project scientists, Dr. Brice Semmens from Scripps Institution of Oceanography, and Dr. Christy Pattengill-Semmens from REEF, hosted three live-from-the-field web chats with students from 18 classrooms at 13 schools in the Cayman Islands, The Bahamas, and Washington State (US). The first of the three web chats was broadcast from the Grouper Moon base of operations on Little Cayman, and featured scientists explaining the research objectives, day-to-day activities, and research equipment used during the project. The other two featured Brice diving and answering questions from the students, first on the Nassau Grouper spawning aggregation and then on the famous Blood Bay Wall. The webcasts are archived online here.
Now in its third year, the Grouper Education Program presents students with a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important species. Key curricular concepts include: the historical role of Nassau Grouper in the Caribbean, its role as a top predator and its positive impact on local reef health, and the conservation challenges facing the species.
Brice Semmens, who presented the underwater webcasts, said students were excited to witness science in action. “As they explore the aggregation with me, the immediacy and reality of the experience really touches them. We are giving students their first diving experience – and it happens to be with thousands of huge, endangered reef fish.”
The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support is provided by Southern Cross Club, Little Cayman Beach Resort and Reef Divers, Cayman Airways, and LIME.
REEF staff co-authored a new publication in the scientific journal PeerJ that features research findings from our Invasive Lionfish Research Program. The paper, titled "Setting the record straight on invasive lionfish control: Culling works", evaluates the effectiveness of lionfish removal efforts. Frequent culling of the invasive Indo-Pacific Lionfish throughout the Caribbean has been shown to cause a shift towards more wary and reclusive behavior by lionfish, which has prompted calls for halting culls. The paper addresses those concerns and reviews research conducted by REEF and other efforts. Culling successfully lowers lionfish numbers and has been shown to stabilize or even reverse declines in native prey fish. Partial culling is often as effective as complete local eradication, yet requires significantly less time and effort. Abandoning culling altogether would therefore be seriously misguided and a hindrance to conservation. The authors also offer suggestions for how to design removal programs that minimize behavioural changes and maximize culling success. The paper is available for online viewing here. You can find a complete listing of all publications that feature REEF's programs at www.REEF.org/db/publications.
If you haven't participated in one of our free, educational webinars yet, you don't know what you are missing! Known as Fishinars, these hour-long sessions enable you to learn and have fun from the comfort of your living room. Check out the full schedule at www.REEF.org/fishinars. And keep an eye on that space because we are always adding new ones. We recently added a new Fishinar scheduled for March 26th that will cover common fishes and invertebrates found in San Diego's La Jolla Canyon. The remaining schedule includes...
Explore our Fishinar webpage, register for the sessions you like, and we'll see you online! You can also request viewings of archived Fishinars, a special perk for REEF members. No special software or microphone is required - just a computer with speakers and an internet connection. And did we mention they are FREE to REEF members!
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 scientist from Bermuda Institute of Ocean Sciences (BIOS) requested REEF data to evaluate fish assemblages in Bermuda with regard to no-take reserves, comparing shallow vs. deep water habitats, and to evaluate the impact of invasive lionfish.
- A scientist from Washington State Department of Transportation requested REEF data to help evaluate the impacts of a proposed ferry terminal at Keystone Jetty on three species of protected rockfish.
- A graduate student from University of Miami requested REEF data from New Providence, Bahamas, to compare the measures of rugosity used in various research research methods and their ability to predict fish diversity and abundance.
A complete list of scientific publications featuring REEF programs and data can be found at www.REEF.org/db/publications.
Last year we shared an article about a new non-native fish, the Regal Demoiselle (Neopomacentrus cyanamos), showing up in the southwestern Gulf of Mexico. REEF surveyors in the Yucatan region of Mexico have since reported the species. And now a new publication co-authored by REEF staff Lad Akins documents that the species could become established and spread in the western Atlantic. The study incorporated a computer model to evaluate the the non-native species’ potential to impact native populations. On the basis of this work, it is foreseeable that the reefs presently harboring Regal Damselfish will likely see increased abundance of this damsel. Immediate attempts to eliminate the fish, therefore, should be focused in nearshore shallow waters spanning Veracruz to Frontera, Mexico. To find out more about this study, published last month in the journal Marine Biology, and to see a complete list of the 50+ scientific publications that have featured REEF data, visit www.REEF.org/db/publications.
The species is native to the Indo-Pacific and Red Sea. Similar in appearance to the native Brown Chromis, the Regal Damsel is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the fins and tail. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin.
If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.
We have one week left in our summer matching campaign, and want to thank everyone who has given so far. This summer, we are highlighting all the amazing discoveries made possible by generous donations from members like you!
To make a contribution, please visit www.REEF.org/donate.
According to the National Oceanic and Atmospheric Administration (NOAA), “To date, we have explored less than five percent of our oceans.” What does that mean for REEF and our members? It means that there is so much out there to discover! Every year, REEF members are finding new species, and REEF scientists are investigating the lifecycles and behaviors of critical marine species. We are constantly learning new things about ocean wildlife that contribute to their survival.
It also means that all these new discoveries can help regulatory agencies and policymakers to make more informed decisions on how to manage our fisheries. In cases like the threatened Nassau Grouper, seasonal protections during spawning seasons have been developed. In the case of invasive species, like lionfish, removal events are being encouraged because they have been proven effective at controlling lionfish populations.
Please take this opportunity to make a contribution this summer and help REEF continue to make these important discoveries that ultimately protect marine species around the world! Thank you again to all our members who support us in our mission, and have a great summer!
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.

REEF recently completed our AAT monitoring of Biscayne National Park (BNP). Over the last two years, we have monitored fish assemblages inside the marine park at 6 separate locations twice each year (March and September) to correlate our results with historical data that BNP has collected. REEF’s future collaboration with BNP is yet to be determined but will likely involve assisting them with the potential establishment of a protected area somewhere within the Park’s boundaries. REEF is excited to have this opportunity to continue working with BNP this upcoming spring so please stay tuned for more information once our future project is defined.
Meanwhile, I would like to personally thank the monitoring team from our last event for their “above and beyond the call” efforts to get the job done. We had weather issues that delayed the project by a full week, followed by a tragic death in the Key Largo diving community in losing Mike Smith. All of us at REEF especially acknowledge Lad Akins for his efforts as our boat captain, Rob Bleser (owner of Quiescence Dive Shop where Mike worked) for pushing this project through under very difficult circumstances, and Steve Campbell for acting as boat captain on our last day. And thank you to the diving team for juggling your schedules to make sure we had enough divers each day: Jesse Armacost, Dave Grenda, Brian Hufford, Lillian Kenney, Mike Phelan, and Joyce Schulke. Everyone pulled together through the above challenges and I was proud to dive with each of you.
