Grouper's Last Stand

nassau_steph.jpg

We are happy to share with you a short (3-minute) Public Service Announcement (PSA) from the REEF Grouper Moon Project, featuring spectacular underwater footage and the hopeful story of the Nassau grouper in the Cayman Islands. The video discusses the importance of protections for spawning aggregations and the work that REEF and our collaborators at the Cayman Islands Department of the Environment (CIDOE) and Oregon State University have done on this important conservation issue. The PSA is on REEF's We Speak Fish YouTube channel -- http://www.youtube.com/user/WeSpeakFish

Cayman Island spawning aggregations have been seasonally protected from fishing for the last 8 years at all current and historic aggregation sites. This protection expires at the end of 2011. The status of future protections for the aggregations is still uncertain. Based on the research and findings of the Grouper Moon Project, the CIDOE has recommended a permanent seasonal closure during the spawning season (Nov-Mar) for Nassau grouper.

The Faces of REEF: Member Spotlight, Douglas and Jane Rorex

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.

Honoring Our Golden Hamlet Club Members

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?

Grouper Moon Scientists Talk Live with School Children From Under the Waves

Grouper Moon researchers, Brice Semmens, Christy Pattengill-Semmens, and Steve Gittings, join educator, Todd Bohannon, for a live-from-the-field chat with Caymanian classrooms. They explained a typical research day and showed much of the research equipment used.

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 DiversCayman Airways, and LIME.

Putting It To Work: New Publication on Effectiveness of Lionfish Culling

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.

REEF is asking any interested REEF members to submit to us a Field Survey T-shirt design for our upcoming 2008 season. Those of you who have participated in the past on a REEF Field Survey know that you receive a t-shirt as part of your participation in the program and every year we have a different design. There are only a couple of guidelines for you. Our new REEF Shirt must incorporate our REEF flag with our slogan, Diving That Counts! (I will send interested parties the jpeg file upon request). You do not need to incorporate the dive flag directly into the design, it may simply be on the front breast pocket of the t-shirt, for instance, with your design on the back and in this case, no need to ask
for our logo, we'll take care of that.

You should keep in mind our mission as stated on the top of our homepage, and our mantra, "diving that counts." Also please keep in mind that REEF actively surveys in 5 regions, not just the tropical western Atlantic. Please send your submissions to joe@reef.org, making sure they are in an easily readable format such as a jpeg file (preferred). Please send all entries in by Dec. 31, 2007.

Depending on the number of submissions we receive, we may have our members vote on the winner in January of 2008. Past t-shirts have had fish images, divers surveying, cartoons depicting divers surveying with witticisms, watercolors of fish, etc. Most importantly, our t-shirt design should incorporate the conservation-based focus of our Field Survey Program.

Thanks in advance for your participation and our staff will look forward to your entries. First prize will be a signed and framed 2008 Paul Humann print of two beautiful Eagle Rays.

 

Field Survey Season 2008 - 5 Spaces are still available for our Turks and Caicos Liveaboard on Aggressor II, April 19-26, 2008.
Please contact Travel for You at 1-888-363-3345 or Joe Cavanaugh at 305-852-0030. The 2008 Field Survey page will be completed shortly - please check back in a week for final content.

Grouper Moon Project Kicks Off Expanded Research Efforts

Thanks to a three-year grant from the Lenfest Ocean Program at the Pew Charitable Trusts, REEF and collaborators at the Cayman Islands Department of the Environment (CIDOE) and Oregon State University (OSU) will greatly expand the conservation science research being conducted as part of the Grouper Moon Project in the Cayman Islands. The funded research, entitled "The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management" will evaluate the potential for spawning site MPAs to recover Nassau grouper stocks.

In 2003 the Cayman Islands government protected all five known current and historic Nassau grouper spawning sites in the Cayman Islands. This move was motivated by the 2001 discovery and rapid depletion of a large spawning aggregation (~7000 fish) on the west end of Little Cayman. This rapid legislative response protected the west-end spawning site before all the fish were taken (~3,000 remain), and the site is now one of the largest fully-protected Nassau grouper spawning aggregations in existence. However, the other four spawning sites had previously been fished to exhaustion and are believed to be inactive, i.e. aggregations no longer occur during spawning season.

Over the next three years, REEF will continue the ongoing aggregation monitoring and acoustic research that has been conducted on the Little Cayman aggregation since 2002 and expand efforts to Cayman Brac and Grand Cayman, where historical spawning aggregations were fished out during the last ten years. Four primary research questions being asked as part of the Lenfest-funded project are: 1) Do aggregations form in regions that have been fished out? 2) If aggregations form, do the fish ultimately spawn? 3) Do these aggregations form at historic sites or somewhere else? And, 4) Does spawning at these remnant aggregations result in new recruitment?

The new research kicked into gear last month with a team of Grouper Moon scientists and REEF volunteers who conducted twelve days of field work in Little Cayman and Cayman Brac. The team visually monitored the Little Cayman aggregation, documenting the largest number of fish since the fishing ban was implemented in 2003. Spectacular mass spawning was documented at dusk seven days after the full moon. Grouper Moon scientists conducted extensive work on Cayman Brac to enable future visual monitoring on the historical aggregation site and initiate an acoustic tagging study that will facilitate a better understanding of the behaviors of Nassau grouper on an island with a limited number of reproductively-aged individuals. Later this Spring and Summer, REEF researchers, volunteers and an OSU graduate student will return to the Cayman Islands to conduct larval recruitment studies and begin acoustic tagging on Grand Cayman.

Capitalizing on the the increased breadth of research questions being asked as part of the Lenfest Ocean Program grant, the CIDOE is supporting a larval dispersal study that also kicked off this year under the guidance of Dr. Scott Heppell from OSU. Three satellite drifters were deployed at the Little Cayman aggregation site on the night of spawning. The paths will be recorded by ARGOS satellites for 45 days and the resulting data will be used to develop a larval dispersal model in collaboration with researchers from University of Miami. Check out the 2008 image gallery to see where the drifters are today.

Visit the Grouper Moon Project webpage to find out more about this critical conservation research program and the 2008 Gallery page to see images and video of the field work.

REEF extends a big thank you to the island business who continue to support this project, including the Little Cayman Beach Resort and the Southern Cross Club, as well as Peter Hillenbrand and Mary Ellen Cutts, Franklin and Cassandra Neal, and the 2008 REEF Volunteer Team -- Judie Clee, Brenda Hitt, Denise Mizell, and Leslie Whaylen.  We also greatly appreciate the continued support of our collaborative team, including the CIDOE and OSU, and the Lenfest Ocean Program at the Pew Charitable Trusts.
