Active REEF surveyor, Mike Bear, and other San Diego area divers started noticing something unexpected earlier this year -- increasing numbers of encounters with the Bluntnose Sevengill Shark, Notorynchus cepedianus, also known as the Broadnose Sevengill shark. Knowing first hand the impact that divers and snorkelers can have as citizen scientists, Mike set up a website - http://sevengillsharksightings.org -- to serve as a central repository for photographic, videographic and written data on these magnificent creatures. Submissions on the site will allow REEF surveyors who are lucky enough to encounter this prehistoric species to provide additional information and images beyond the sighting and abundance information recorded as part of their REEF survey. It will also enable divers who were not doing a REEF survey to report their encounter. One of the most interesting parts of the website will be the development of an informal photographic database of Sevengill sightings that will facilitate the comparison of photographs and the potential identification of individual sharks using the unique pattern of dark "freckles" on the backs of each shark, similar to the patterns seen on whale sharks. To date, six REEF surveys in San Diego have reported a Sevengill (click here to see the sightings report).

The second annual Abaco Lionfish Derby, held at Green Turtle Cay, Bahamas, on Saturday June 19th, was a huge success. Teams on twenty-one boats from Florida and the Bahamas enjoyed perfect weather and conditions while collecting a grand total of 941 lionfish. Over $5,000 in cash was awarded to the winning teams for the most, biggest, and smallest lionfish. This event, held in the Bahamas and sanctioned by the Bahamas Department of Marine Resources, is one of many REEF efforts to cull invasive lionfish populations and raise awareness about the issue.

The award for most lionfish collected in the one-day event went to team White Roach from Abaco. Repeat winners, the trio of skilled lionfish collectors significantly exceeded their tally from 289 lionfish last year to a whopping 345 this year. This number is both astonishing and alarming when you consider how dense lionfish populations must be for three people to have the ability to collect over 300 lionfish in the span of a single day.

Team Meander from Jacksonville, FL, clenched 1st, 2nd, and 3rd place for largest lionfish collected. Zane Carney captured the largest lionfish ever recorded in the Abacos, which measured just 2cm short of the national record. Zane told Derby organizers that he found a hole outside the main barrier reef off of No Name Cay in 45 feet of water that was full of very large lionfish. He used a pole spear to bag the winning fish, which was 43.4 cm in length (roughly 19 inches long) and weighed approximately 4 pounds.

Lad Akins, REEF’s Director of Operations, and Stephanie Green, a collaborative research partner from Simon Fraser University, recorded valuable data during the event, including lionfish sizes, stomach contents, and sex for many of the lionfish before they were filleted and cooked by the Green Turtle Club. Observers and participants, many of whom had never tried lionfish, found the fish quite tasty, resembling hogfish or grouper. This year, Tropic Seafood Limited of Nassau also arranged to purchase some of the larger fillets of lionfish for distribution in local markets. According to Derby organizer, Bobbie Lindsay, “Tropic’s offer to purchase lionfish is an exciting development, because creating a market for lionfish is the best way to control the population of this invasive fish.”

Thanks to the Derby co-sponsors, Green Turtle Club, and Brendal’s Dive Center, who offered special discounts for Derby participants. REEF also extends sincere gratitude to all of the participants, and especially Bobbie Lindsay, an active REEF member and volunteer who took the lead in organizing the Derby making it a successful event again this year. Next year’s Derby is set for June 24-25, 2011. For full results and pictures go to www.lionfishderby.com.

    Attention Tropical Western Atlantic fishwatchers -- the Neon Goby has been split into two species. The original Neon Goby, Elactinus oceanops, retains the common name and is geographically known only from So. Florida and Flower Gardens and Alacran reefs in the Gulf of Mexico. This goby can be distinguished by the bright neon blue stripe from snout to tail with a sharp blue-against-black edge.

    The Caribbean Neon Goby (new common name), Elactinus lobeli, is known only from the Bay of Honduras, from Xcalak in Yucatan through Belize to the Bay Islands of Honduras, including offshore reefs. It can be distinguished by the pale blue or grey borders along the bright blue neon stripe running from snout to tail. Genetic analyses indicate that the two species have been separated for about 800,000 years.

    REEF recently awarded Nancy Perez the 2010 Key Largo Community Volunteer Award. Nancy joined during REEF's inaugural year in 1993! She lives in the Florida Keys and has become an instrumental volunteer at REEF Headquarters in Key Largo. Nancy helps connect REEF with the local community through planning special events, including holiday parties, the James E. Lockwood REEF Headquarters dedication, and participation at local festivals. Nancy has also encouraged other locals to volunteer at REEF HQ and is always available to assist REEF staff on projects. Nancy's biggest impact has been through her role coordinating the Fish and Friends gatherings at REEF HQ. During these popular monthly meetings, which started in 2009, REEF supporters come together to socialize with fellow fish followers and listen to presentations about various marine species and habitats. The success of this event would not be possible without the hard work and time that Nancy puts in to finding speakers, getting volunteer hosts, coordinating the snacks and beverages, and always wearing a smile. Her tireless dedication to the REEF Fish and Friends event is admired by all. In her spare time, Nancy is out diving and completing REEF surveys! On behalf of the REEF Staff and Board of Trustees, we extend Nancy our deepest appreciation.

    REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.

    This month we highlight Dave Grenda (REEF member since 1998). After retiring from the military, he became a volunteer, divemaster, and an American Academy Of Underwater Sciences Scientific Diver at the Florida Aquarium in Tampa. Dave has conducted over 1,800 REEF surveys and is a Level 5 Expert surveyor. In addition to his own diving activities, Dave has participated in numerous research projects, including numerous REEF Advanced Assessment Team trips, Nassau grouper tagging in the Caymans, mutton snapper spawning in the Dry Tortugas, piscivore cooperative hunting research off Georgia (see "Putting it to Work"), queen conch population surveys in St. Croix, Aquarius undersea laboratory support in Key Largo, Tampa Bay Civil War shipwreck archeology, Paleolithic Indian archeology in North Port Florida, coral spawning in the Flower Gardens and Key Largo, Gulf Red Tide recovery, reef health assessments with the Living Oceans Foundation in the Caribbean, point/transect fish surveys throughout the Keys, and collecting exhibit animals for aquaria educational displays. Here's what Dave had to say about REEF:

    When and how did you first hear about REEF? What is your favorite part about being a REEF member? I became involved with REEF after attending a fish ID lecture at the Florida Aquarium given by John Pitcarin - a founding REEF staff member. Being a REEF member has opened an entirely new world to me. The fish identification skills I've acquired through REEF has opened many doors for me as a citizen scientist. I'm extremely grateful for the many opportunities I've been provided through my association with REEF. Attaining Expert survey level has enabled me to join numerous research efforts with NOAA, National Park Service, Universities, Aquaria, and of course REEF itself. Working with marine scientists has been very interesting and those scientists have relied extensively on my fish identification skills that I've acquired during my REEF survey diving. While these scientists knew their particular specialty very well, they were often rusty in general fish identification. I quickly became a valued member of their team, treated as an equal colleague, and sought after for future projects.

    In your opinion, what is the most important aspect of REEFís projects and programs? Doing REEF surveys not only provides valuable data, it's a great way of "giving back" (helping the aquatic environment), but it also greatly enhances your diving enjoyment. What I like about the REEF survey method is that it can adapt to any type of dive site - regardless of visibility, current, depth, etc. While other divers might be disappointed at the visibility, or the failure to see certain animals (like sharks, turtles, eels, etc.), I will have had a great dive doing a REEF survey. I see more during my dives by doing surveys and I get excited at a rare sighting and adding a new species to my lifelist.

    Do you have any surveying, fishwatching, or identification tips for REEF members? What new fish ID'ers need to do is SLOW down. It's much easier to see the movement of a cryptic fish, or just about any fish, when you aren't moving. If conditions allow, I'll start my dive by hovering in the water column. I'll write down every species I see as I slowly make a complete turn - looking in the water column as well as on the bottom below. To get the most species from each dive site, I'll try to hit as many different environments as possible (sand, rubble, top/middle/bottom of the reef, shallow/deep, etc.). Bring a flashlight to look into crevices and every tube sponge. It also helps to use the REEF database to know what species have been previously sighted at your dive destination. Before the dive you can acquaint yourself with the descriptions of new fish you might see there, so if you do come across that new fish, you'll already know how to identify it. Chance favors the prepared mind. You should also jump at the chance to dive with other fish watching experts. I've learned so much and so quickly by diving with other REEF folks - gaining confidence, learning new techniques, and just sharing wonderful fish stories.

    REEF Trips - Handful of Spaces Remain in 2012, 2013 Schedule Coming Soon

    Roatan10groupshot.jpg

    REEF Field Surveys trips that are a great introduction to fish identification for novice fishwatchers, and a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. REEF coordinates Field Surveys to locations throughout our project regions each year. These projects are led by REEF staff and other REEF instructors and feature daily classroom seminars and a full diving schedule. Many of the 2012 REEF Field Survey trips are sold out, but there are still a few spots on the lionfish research expedition to Dominica, the fish behavior trip to Bermuda, and a liveaboard through the British Virgin Islands. We are also working on an exciting lineup for the 2013 schedule. We will announce the full lineup and details soon. Destinations include Fiji, Curacao, Turks and Caicos, Utila, and the Soccoro Islands. Get in touch with our travel experts at Caradonna to find out more and to book your space - 1-877-295-7333 (REEF), or via e-mail REEF@caradonna.com. The full schedule and more information can be found online at http://www.REEF.org/trips.

    REEF's Volunteer Survey Project is Turning 20! Save the Date.

    To celebrate 20 years of ocean conservation and education through the Volunteer Survey Project, and to honor our members for making these successes possible, REEF will be hosting a fun-filled weekend of diving, learning, and parties -- August 8-11, 2013, in Key Largo. Please mark your calendar and save the date! More details will be announced in the coming months. The first REEF surveys were conducted during a Field Survey trip in Key Largo, Florida, in the summer of 1993. Led by co-Founders, Paul Humann and Ned DeLoach, as well as founding Executive Director, Lad Akins, a total of thirteen volunteers conducted 102 surveys. Almost 20 years later, the REEF Volunteer Fish Survey Project has grown to become the largest ocean citizen science program. Approximately 14,000 volunteer divers and snorkelers have conducted over 165,000 surveys at 12,000 sites throughout the world. These data have been used by scientists, government agencies, and other conservation groups, and have been featured in dozens of scientific publications. Our marine conservation programs, education initiatives, and research efforts are backed by over 50,000 REEF members. We hope you will join us next August to celebrate 20 years of education, surveys, fish stories, and friendships!

    Thank You For Helping Us Reach Our Goal

    On behalf of our current, past, and future REEF Marine Conservation Interns, we would like to thank all those who donated during our Spring fundraising campaign to support our internship program. Thanks to the generous contributions of many members, we reached (and surpassed) our goal, raising $10,196! These funds will help ensure that we can continue this important program and support these enthusiastic young professionals as they gain critical career skills. Although less known, the REEF Marine Conservation Internship Program is one of our most successful endeavors. Our interns are a key part of ensuring smooth operations at REEF Headquarters, as they contribute in so many ways to the daily tasks and activities required to manage REEF’s important programs. Through experiences gained and connections made during their internship, many of our interns have gone on to work at government agencies or other non-profit organizations. Others have gone on to complete graduate programs focused on ocean issues. And several of them have come back to work at REEF!

    REEF Sponsors Grouper Education Workshop

    Educators learned a Food Web Game classroom activity that is part of the Grouper Education Program curriculum. REEF Educator, Todd Bohannon, demonstrates how the food web connections are represented by yarn strung between different members of the coral reef community.

    On December 3rd and 5th, REEF and the Cayman Islands Department of the Environment (DOE) held free educator workshops on Grand Cayman and Cayman Brac in the Cayman Islands. The professional development workshops presented the Grouper Education Program, a marine sciences curriculum for intermediate/elementary and high school students that was developed as part of the Grouper Moon Project. Nineteen teachers from 12 schools participated, including 2 schools from the Bahamas. Participants received the materials and resources necessary for successfully implementing the Grouper Education Program in their classrooms. This exciting project focuses on bringing the Nassau Grouper into classrooms through lesson plans and interactive live-feed video sessions that connect classrooms with Grouper Moon scientists in the field.

    The curriculum presents a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important fish. Key curricular concepts include the historical role of the species as an artisanal fishery throughout the Caribbean region, the grouper’s value as a keystone predator and its impact on local reef health, its role in today’s tourism-based economy in the Cayman Islands and throughout the Caribbean, and the conservation challenges facing Nassau Grouper given steep declines in populations. In addition to classroom lessons, the program includes live-feed video sessions that take place at the Grouper Moon Project research site on Little Cayman, bringing real-world field science into the classroom.

    The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support for the workshops was provided by Cayman Airways, Brac Reef Beach Resort, and LIME. The program curriculum was developed to complement the research and scientific efforts of the Grouper Moon Project. Grouper Moon educator, Todd Bohannon, along with Grouper Moon scientists Brice Semmens, Ph.D. (Scripps Institution of Oceanography), Christy Pattengill-Semmens, Ph.D. (REEF), and Mr. Bradley Johnson (DOE), have led the educational effort. Activities were developed in consultation with teachers at Cayman Prep on Grand Cayman, Verity Redrup and Brenda Bryce, and Cynthia Shaw, author of the youth fictional book, Grouper Moon.
