We are excited to share a new scientific paper published last month in the journal PLoS ONE that included REEF data - Global Population Trends and Human Use Patterns of Manta and Mobula Rays, by Christine Ward-Paige, Brendal Davis, and Boris Worm. Despite being the world’s largest rays and providing significant revenue through dive tourism, little is known about the population status, exploitation, and trade volume of mobulids (Manta and Mobula species). There is anecdotal evidence, however, that mobulid populations are declining, largely due to the recent emergence of a widespread trade for their gill rakers. Researchers from Dalhousie University and eShark.org used expert divers’ observations from two citizen science programs, REEF's Volunteer Fish Survey Project and eShark.org, to describe global manta and devil ray abundance trends and human use patterns. The study highlights the relative rarity of aggregation sites on a global scale and reveals that many populations appear to be declining. The authors warn that newly emerging fisheries for the rays gill-‐rakers likely exceed their ability to recover. The study also demonstrates the deficiency of official catch reports, as only four countries have ever reported landing manta or devil rays– Indonesia, Liberia, Spain, and Ecuador. However, numerous diver reports compiled in the paper illustrate that many other countries are regularly landing and selling these rays without reporting.

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:
- Scientists from NOAA Southeast Fisheries Science Center are evaluating the status of Lesser Electric Ray in the Caribbean.
- A scientist from NOAA Northwest Fisheries Science Center Fisheries Conservation Biology Division is including REEF data in an evaluation of threatened rockfishes in Washington State.
- A researcher from Simon Fraser University is using REEF data to evaluate the lionfish invasion in the western Atlantic, with specific interest the impact it will have in Brazilian waters.
- A graduate student from the University of Exeter is using REEF data to evaluate Nassau Grouper populations in The Bahamas.
A complete list of scientific publications featuring REEF programs and data can be found at www.REEF.org/db/publications.
Here are a few notes and news bits we'd like you to know about:
Thanks to all who have made the beginning of our 2007 Field Survey year a successful start! There are still spaces available on two of our upcoming (see below). Keep an eye out for our 2008 Field Survey Schedule coming out soon in ENews!
WOODS HOLE (Sept 11-16, 2007) - Woods Hole and other New England sites – we have a few spaces left on this first-ever New England Field Survey led by myself, a self-proscribed New Englander. We will be diving Woods Hole, historic Plymouth of Mayflower fame, the historic fishing port of Gloucester, and Martha’s Vineyard. Our accommodations are in the village of Woods Hole that boasts 37 past Nobel laureates. The water temperature will be in the mid 70’s for all but two of our dives and we are sure to see some tropical fish mixed in with the temperate fishes. We will meet some of our New England counterparts in and out of the water. Please join us if you can.
BONAIRE (September 22-29, 2007) – There are 7 spots left on this unique trip led by Ned and Anna DeLoach. Bonaire is a wonderful place to learn your fish ID and benefit from two world experts in fish/invert ID and behavior. Bonaire deservedly boasts some of the best diving in the tropical western Atlantic and you’ll see many species on every dive with no worries about navigation while you gently dive out to the reef wall and turn left or right and follow the wall back. The shore diving is magnificent and you’ll want to take advantage of Ned and Anna’s underwater naturalist acumen and great conversations and stories. Eight of our top ten sites for species richness in the TWA database are from Bonaire. Hope to see you there!

On Friday, November 30, REEF welcomed more than 100 local members and new friends to REEF HQ in Key Largo, Florida for the first annual Holiday Open House. The event was intended to raise awareness about REEF in the community and educate REEF neighbors about critical conservation projects going on in the Florida Keys. The first in a series of signed, limited edition Paul Humann prints was raffled off, authors and photographers Ned and Anna DeLoach signed books and everyone enjoyed celebrating the season with friends and fellow fish watchers.
If you find yourself in the Florida Keys, we hope you will swing by and say hello at 98300 Overseas Highway, Key Largo. Many thanks to the newly formed Key Largo Fun-raisers group for helping with this event: Amy Slate, Evelyn McGlone, Mary Powell, Amy Fowler, and Sharon Hauk.
Hello and Happy April!
In this edition of REEF-in-Brief, learn about exciting work happening in the Turks and Caicos islands, new lionfish information and opportunities and the chance to help REEF collect data in the tropical eastern Pacific. REEF members recently helped the Northwest Straits Commission locate and remove a derelict fishing net in Hood Sound, Washington, while staff and volunteers made a splash at a south Florida Earth Day event. Please mark your calendars for the 17th Great Annual Fish Count (GAFC), taking place throughout the month of July. The GAFC is a great opportunity for fish watchers new and old to contribute to the largest marine life data collection event REEF holds all year.
My bittersweet news is that this is my last week at REEF. I will be staying in the marine conservation community here in the Florida Keys and will continue to support the critical work that REEF does. The Board of Trustees has identified a strong candidate for my replacement, details of which you will be provided soon. I sincerely appreciate the support each of you has shown REEF and hope our paths cross in the future. Until then, best wishes and best fishes,
It is hard to believe that I am already more than half way through my Marine Conservation Internship. The past two months have been full of exciting events that have really inspired me to continue on in the world of marine conservation and biology. After settling into the REEF office for just a few days, the REEF staff had me out and about, getting involved with the community. For a week in mid-June I assisted with Paul Humann’s “Discovery Tour,” diving along side an energetic and enthusiastic group of divers who were learning fish identification and practicing surveying techniques. I was also able to sit in on the Non-Native Marine Fish Introductions of South Florida Technical Workshop, which helped introduce me to the growing problem of Lionfish and the efforts that REEF, along with other organizations, puts forth into researching this growing problem.
July has been just as busy, starting with the International Coral Reef Symposium from July 7-11. This conference happens only once every four years, and fortunately for me, was held in Ft. Lauderdale this year. I had never had the opportunity to attend a scientific conference like this before, but was a great experience due to the many presentations and massive amounts of information I was exposed to each day. It really helped to open my eyes to the different fields of research available. Following the symposium, I was able to participate in the REEF Field Trip associated with ICRS in Key Largo.
I have also been able to work with the Education and Outreach program during my time with REEF. As part of REEF’s Great Annual Fish Count, I participated in a Fish ID Seminar at Biscayne National Park. I also spoke to volunteers at the Dolphin Research Center about REEF and its programs while visiting the facility and learning about the center in June. After hearing many great stories about the infamous Seacamp from Lisa, I spent my first night on Big Pine Key just last week where Lisa and I were the Science Night speakers for a group of campers. The enthusiasm in the room from the kids was off the charts and great to see.
One last highlight of my time with REEF thus far was being able to meet with George Wozencraft, the Internship Coordinator for the Our World-Underwater Scholarship Society that sponsors my Marine Conservation Internship with REEF. I was able to dive with George one afternoon and discuss my internship and many of the opportunities I have had so far. I am looking forward to the upcoming weeks I have left with the REEF staff, and of course, getting out in the water to conduct more fish surveys!
While we all knew it was just a matter of time, the call still came with a bit of surprise and dread as the first confirmed lionfish sighting in the Florida Keys came in on January 6th, 2009. REEF member Becky Fowler, from Greenville, SC, was diving just offshore of the Benwood Wreck in Key Largo when she spotted the invasive lionfish near the base of a ledge at 66'. With all of the recent focus and outreach efforts that REEF has been forwarding to our members, she knew immediately that she needed to document the sighting and gather a detailed description of its location. Upon her return to shore, she called REEF HQ and delivered the report. This set into motion the Rapid Response plan
developed 7 months earlier in a REEF sponsored multi agency workshop (see REEFNotes article). Becky came by the REEF office, the images were verified, and her detailed site description was conveyed to Lad Akins, Director of Special Projects. The report was forwarded to the US Geological USGS alert system and Lad began response coordination with the Florida Keys National Marine Sanctuary (FKNMS) who has jurisdiction of resources at the sighting location.
The following morning, the response team made up of Lad Akins, Lisa Mitchell (REEF Exec. Dir.), John Halas (FKNMS), Frazier Nivens (Ocean Imaging) and Steve Campbell (Quiescence Diving Services) were assembled and on site at 10:30am. Following the excellent location description provided by Becky, the team was able to locate the fish, capture video footage, gather important data on site characteristics and the available nearby prey community, capture and bag the fish in under 14 minutes. The fish was captured live via hand nets, brought back to shore, euthanized and dissected. The 99mm immature male contained one 34mm prey fish in its stomach. Tissue samples, genetic material and other measurements were collected for further analysis by researchers at the NOAA Beaufort lab and Simon Fraser University. No other lionfish were found in the immediate vicinity.
While no one wanted to see lionfish show up in the Florida Keys, most knowledgeable sources believed it was inevitable and simply a matter of time. The one bright side of this story is that advanced planning and preparation initiated by REEF resulted in the awareness, accurate reporting, and successful rapid response effort that removed the fish less than 24 hours after its initial sighting. Hopes are that as lionfish show up in the Keys and other downstream areas, these rapid response efforts will help to control establishments and minimize impacts of this glutinous predator.
REEF continues to encourage divers to report their sightings of lionfish and other non-native fishes with as much detail as possible to www.reef.org/lionfish and to support lionfish research projects such as the January 17-24 project in the Turks and Caicos and the June 13-20 project in Belize. For more information, contact Lad Akins (Lad@REEF.org) (305) 852-0030.
If you are a REEF surveyor in the Tropical Western Atlantic, you are probably familiar with the Peacock Flounder (Bothus lunatus). And if you spend much time in the sand, you probably even know about the smaller Eyed Founder (Bothus ocellatus)? But how about the Spiny Flounder (Engyophrys senta)? Danielle Calini, an Our World Underwater Scholar who spent this summer as an intern at REEF HQ in Key Largo, was one of several REEF surveyors who recently came across this rarely seen species during a dive on Molasses Reef. And while this was the first record of the Spiny Flounder in the REEF Florida Keys database, it turns out this species might not be as rare as we think.
Spiny Flounder are very similar in appearance to the common Eyed Flounder, and it's likely that surveyors might not be looking closely enough when they see the small flatfish scurrying across the sand. It was previously thought that cirri extending from the eyes were a key feature distinguishing the two species but the cirri are very difficult to see. According to Paul Humann, Spiny Founder can be distinguished from Eyed Flounder by three key features:
REEF is proud to host an Our World Underwater Scholar each summer. In addition to tracking down rare species, OWU interns provide much needed help in the REEF HQ office and conduct outreach with the Florida Keys community. The REEF Staff and Board of Trustees extends a big fish thank you to Danielle in appreciation for her service to REEF in the Summer 2009.Share on Facebook
Five years ago, with a group of volunteers, I produced the first DVD volume of Sensational Seas, an anthology of underwater images as seen through the eyes of 25 filmmakers and photographers. Each filmmaker generously donated his or her work, which enabled us to turn those contributions into a great fundraiser for REEF. The DVD was a big success and when REEF staff mentioned in late 2008 that their supply was nearly gone, we knew it was time to produce another volume. Thanks to the Carrow Foundation, who provided the production funding, REEF will be beneficiary of the sales of a new DVD, Sensational Seas Two. The DVD is available for purchase from REEF through the online store -- http://www.reef.org/store/sensationalseastwo.
In Sensational Seas Two, thirty divers from distinguished scientists and seasoned professionals to talented amateurs, take you on a grand tour of watery realms as far-flung as Antarctica, Australia, the Andaman Sea and Georgia Aquarium. Expect the unexpected, come face-to-face with the gentlest of giants, a rolling octopus, spawning frogfish, a snorkeling elephant, and tiny plankton that epitomize the grandeur of nature’s artistic flair. We like to say this collected work is a fitting way to express just why we love to dive.
A lot has changed since our first production in 2004. Online sites like YouTube provide venues for people to share their videos and social networking enables us to share links to myriad underwater images. What sets Sensational Seas Two apart is the cooperative effort between underwater filmmakers, photographers, musicians, graphic designers, writers and programmers - all divers – who donated their skills and art to produce this spectacular collection of underwater images, for the benefit of marine environmental causes.
All of the proceeds from every Sensational Seas Two DVD purchased from the REEF store will go directly to REEF. Your purchase will help REEF continue its important work. Thank you for your support and enjoy the show!
To learn about the DVD and the people who donated their time and images to Sensational Seas Two, visit www.SensationalSeas.com. For a preview of Sensational Seas Two, watch the trailer on YouTube here.
