As we celebrate REEF Member #50,000, it is exciting to also look back to the beginning. This month we feature two of our charter members, Douglas and Jane Rorex (REEF Members #25 and #26). Nineteen years ago this month they were diving in the Florida Keys and happened upon information about what was to be the first REEF Survey Project class in July 1993. They couldn't attend that one, but they did attend a class a few months later. Since then, Douglas and Jane have conducted over 400 surveys combined. Here's what they had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
We still have the letter from Laddie Akins confirming our being a part of this second class, that took place starting 17 October 1993. The week-long project included 12 dives and surveys along with the daily lessons. It was a blast. It was the best course we had ever had in Scuba in that it enabled us to enjoy our diving ever so much more as we came to recognize what we were actually seeing. Ned DeLoach, Paul Humann, Gloria Teague, and Laddie Akins were all wonderful. Laddie was our primary teacher and has been a mentor, friend, and teacher ever since. Over the years, REEF has continued to provide educational materials, and those combined with books by Ned and Paul have expanded our enjoyment from not only identifying fish, but also watching their behavior. We really enjoyed diving with Ned and Anna DeLoach this past year, where we kept an eye on a pair of courting Frogfish.
Do you dive close to where you live, and if so, what is the best part about diving there?
Most of our Midwest diving involves quarries, lakes, cowponds, caves (springs), and/or rivers. I (Doug) have done all of the former, but presently do most of my local diving in Missouri caves. There is a sense of adventure and exploration and accomplishment in cave diving that is somewhat missing from most cowponds, plus you don't have to run the cattle out of the cave before you dive. The fish life is not as abundant, but there is plenty to see. Cannonball Cave in Missouri is the cave I have explored most thoroughly. I have explored back more than a 1/4 mile and to a depth of 365 feet. The cave is stunning and has beautiful clay formations that are breath-taking.
What is your favorite fish or marine invertebrate?
The juvenile Yellowtail Damsel. We called it by the name "Jewel" fish when we first started diving. Our signal to each other identifying the fish is to hold out one hand and peck on it with the forefinger of the other hand indicating the bright, jewel like dots that adorn the juvenile. We usually spend time at the end of each dive in the shallows among the fire coral on Bonaire looking at interesting fish and creatures, but the tiny Yellowtail Damsels is our favorite. I suppose its our favorite because of its stunning beauty and its also nice getting to see your favorite fish every dive.
What is your most memorable fish find? Is there a fish (or Marine invertebrate) you haven't seen yet diving, but would like to?
Diving Bonaire in the middle 1990's we kept seeing this tiny goby. I drew it and sent the drawing along with a description to Laddie Akins. Laddie had previously identified dozens of fish for us in this manner, (for example, the Cave Bass and the Black Brotula), and, that he could do it was amazing. This fish he eventually identified as an "Island Goby." It was eventually recognized as the same fish by a previous name: "the Semi-scale Goby." I have drawings of it in log pages from those early days and still think of it as an Island Goby, though, on survey sheets I list it otherwise.
We have not seen either a Whale Shark or a Shortnose Batfish. But we're keeping the dream alive...and they are out there awaiting us.

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.

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.
REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Anne Benolkin. Anne was a REEF Marine Conservation Intern in the spring of 2013. She grew up in Alaska, and after going to college and interning in Florida, she returned to her frosty home state. Following her time as a REEF intern, Anne went on to become a Pro SCUBA Instructor and was awarded the prestigious Zale Perry scholarship, an award named after one of diving’s most celebrated women and the memorable lady-star of “Sea Hunt” (read more about Anne's award here). She is currently working on her Masters degree at Alaska Pacific University, studying the behavior of Day Octopus. Here’s what Anne had to say about her time at REEF and beyond:
What did you enjoy most about your experience as a REEF intern?
When I was a REEF intern my favorite thing was all of the connections I got to make with people all over the world. It was so inspiring to see this community of people brought together by a desire to make the world a better place. I loved leading seminars and teaching enthusiastic people all about reef fish and conservation. I especially loved watching people come together for a cause, like the work REEF does with the lionfish invasion. We took something negative and looked for positive solutions that bring people together.
What inspires you to do REEF surveys?
Diving is such a unique sport. There are a huge variety of people who come from all different backgrounds and they all got into diving for different reasons. Learning about fish and doing REEF surveys adds a whole other element to diving, making every dive uniquely exciting with new things to discover. I feel like I’m making a contribution when I do a REEF survey.
What are you doing these days, post-REEF internship?
My internship at REEF opened a lot of doors for me. I’ve since gone on to become a SCUBA instructor and enroll in a masters degree program. I moved back to Alaska and I was so thrilled when they expanded the REEF sites to include Alaska. I think sometimes people forget about the beauty and diversity that exists in cold water diving.
This month, we are excited to introduce you to our Fall 2016 interns, who are a part of our Marine Conservation Internship Program. Since 1994, REEF has hosted over 110 interns. Our internship program has expanded over the years and our interns serve an important role in the day-to-day management at REEF. The internship provides an array of diverse experiences including scientific diving, outreach and education, data collection and management, non-profit operations, and public speaking.

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.
