On behalf of the REEF Staff and Trustees, I want to thank all the donors from our Winter Fundraising campaign who helped us reach our target goal. With your help, we can continue REEF's core conservation programs, such as fighting the Lionfish invasion in the Caribbean, protecting Grouper spawning aggregations, collecting data through our Volunteer Fish Survey Project, and providing free online "Fishinars" to the general public and fish experts worldwide.
If you haven't given already, there are a few days left in our campaign to receive my limited, signed print of a Grouper Moon aggregation for contributions of $250 and over. In addition to donating online, you can also call REEF Headquarters at 305-852-0030, or mail in your donation to REEF, PO Box 246, Key Largo, FL 33037. Thank you again for your support!
Earlier this summer, we proudly released the next generation of REEF survey technology, the REEF Data Entry Program. When surveying began in 1993, divers and snorkelers wrote out each sighted fish species on a slate and submitted the surveys to the database using paper scantron forms. In 1994, we developed pre-printed underwater survey paper to make surveying easier, and in 2005 we said goodbye to bubble-filling and premiered online data entry using the Internet. The time had come to innovate yet again.
With our members in mind, we looked to develop a data entry tool that would meet the varied needs of our surveyors, including those who are traveling or live in areas with limited Internet access. The REEF Survey Data Entry Program allows our volunteers to enter REEF surveys without an Internet connection. When they have access to the web, the entered surveys are uploaded to the REEF online entry portal. Users then logon to the portal, complete error checking, and submit the surveys to REEF. The program operates on both Mac and PC computers, and is available for all of REEF’s survey regions. Our Beta-testers and early users agree it’s a great program, and many of them prefer the offline data entry program over online data entry.
The program is free to download at: www.REEF.org/dataentryprogram. Give it a try next time you survey! We hope you enjoy the program as much as we do. Feel free to send feedback to data@REEF.org. REEF extends a huge thank you to programmer, Chris MacGregor, for his work on this project, as well as REEF members who encouraged us to pursue this option and made contributions to support its development.
Data generated by the REEF Volunteer Fish Survey Project provide an unparalleled opportunity to examine patterns in reef fish diversity (the number and types of species) at the scales of reefs, regions, and even an entire ocean basin. Authors of one recent scientific study took advantage of the over 25,000 Expert REEF surveys conducted at 80 sites from 6 Caribbean ecoregions over 17 years. The authors of the paper, which was recently published in the journal PLoS ONE, used the REEF data to evaluate patterns of biodiversity across many spatial scales (from individual sites to ecoregions). They also incorporated factors such as fisheries impacts and how connected different regions are to each other through ocean currents. They compared levels of different types of diversity-- alpha diversity (α-diversity) that explains local diversity (the number of species found in a given place), and beta diversity (β-diversity) that explains the difference in diversity among sites. Their results showed that fish assemblages are more homogenous than expected, particularly at the ecoregion scale. Within each ecoregion, diversity was mainly attributed to alpha diversity, indicating that fishes within each ecoregion are a subsample of the same species pool. Studies like this one that examine regional patterns of diversity in coral reef systems are important because of declining biodiversity in many areas.

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’s Office of Protected Resources are using REEF data to evaluate populations of seabass and grouper in the Caribbean.
- A scientist from the University of Washington School of Marine and Environmental Affairs is using REEF data on fishes and invertebrates to evaluate MPAs in the Puget Sound.
- A professor from California State San Luis Obispo is using REEF data to evaluate populations of three large parrotfish species in the Caribbean (Blue, Midnight, Rainbow).
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 Joyce Schulke, one of REEF's earliest members. She has been a REEF member since 1996. An active surveyor who lives in Florida, Joyce has conducted almost 900 surveys to date and has been a member of REEF's Advanced Assessment Team for the Tropcial Western Atlantic region since it's beginnings. Here's what she had to say about REEF:
How did you become involved with REEF?
In 1989 I snorkeled in Cancun. Diving lessons followed and the underwater world was wide open. Being a professional photographer, it was natural for me to learn underwater photography as well. Identifying those fish led me to the Humann and DeLoach book, Reef Fish Identification. It talked about REEF and so I followed through and became a fish surveyor in 1996. In 1999 I qualified as a member of REEF’s Advanced Assessment Team. Being a surveyor inspired me to look harder and enjoy each dive more.
What inspires you to complete REEF surveys?
Suddenly, even common fish are important to find and record. It is exciting to be part a larger goal and I have gotten a good idea of distribution of species, habitat, behavior, and changes to specific areas over the years. There is always a surprise. After diving to 130 feet to see my first Purple Reeffish in the southern Caribbean, I found one at 13 feet in Marathon Key. Recently, seeing the Longnose Batfish far from its normal habitat in 13 feet of water at Blue Heron Bridge in West Palm, Florida, is another great example of the treasures awaiting those who really search.
I have specialized in the TWA and have done all of my diving there. I get enthusiastic when talking fish. I have currently seen and identified 519 species of TWA fish. My husband, Tom, and I used to divide the cost of a dive trip by the number of new species we found. You can imagine how expensive some of those species have become!
Where is your favorite place to dive?
Without hesitation, St. Vincent has added most of my unusual finds, with dozens of new species added on each trip. One trip produced 18 species of eels alone. The diversity of types of diving spots and willingness of Dive St. Vincent to take us to the odd spots makes this a favorite. However, now that I live in Florida, the lure of Blue Heron Bridge in West Palm, has added a few more dozen new species in the last two years.
What fish am I looking for now?
If I haven’t seen it yet, I want it! Whether it’s a Spanish Sardine or a Longnose Batfish, I’m elated. Of course, when I see one that’s never been on a REEF survey before, I grin while emailing REEF for a new fish code.
What do you say to others about joining REEF?
I cannot encourage others enough. Being a REEF surveyor is a great contribution to ocean research and preservation. The real bonus, however, is how it adds a whole new purpose and enjoyment to your personal diving adventures.
Acoustic tagging is one of the most powerful marine conservation technologies currently available. REEF uses this technology in both the Grouper Moon Project and the Invasive Lionfish Program to help determine movement, ranges, behavior, and more. But tags and receivers are expensive! We need your help in furthering REEF's valuable marine conservation initiatives by supporting the purchase and implementation of these valuable tools. You can donate securely online at www.REEF.org/contribute. Read on to learn more about these high-tech tools.
What is an acoustic tag, hydrophone, and array? Acoustic tags are small electronic devices that, once secured to a fish, broadcast their identification by ultrasonic sound. Hydrophones that can detect these ultrasonic sounds are placed underwater via a buoy to record the presence or absence of fish. A group of hydrophones strategically placed in an area is called an array. Data from the array are periodically downloaded and analyzed to determine fish movement, residency, behavior, and more.
How do tagging studies make a difference for marine conservation?
REEF's Grouper Moon Project has relied heavily on this technology to help answer questions necessary to hep conserve Nassau Grouper spawning aggregations. Populations of this iconic species have declined dramatically over the past half-century due to overfishing during winter months as they aggregate to reproduce. To find out more about this activity, REEF researchers and our partners at Cayman Islands Department of Environment set up an array of acoustic receivers and started tagging Nassau Grouper in 2005. Using data from this technology, REEF created a video that shows the remarkable migrations Nassau Grouper undertake during the spawning season. This visualization tool played a critical role in the creation of proposed legislation aimed at species conservation in the Cayman Islands. To watch this movie and read more about it, please click here.
Please make a donation at www.REEF.org/contribute so REEF can continue using acoustic tagging in projects and programs. This valuable tool helps ensure that we can protect iconic species like Nassau Grouper in the most effective manner. Thank you for your support.
In the first few weeks of July we have started receiving reports of several Manta ray sightings at French Reef, near Key Largo, Florida. Mantas are found in the temperate, tropical, and sub tropical waters world wide. However, sightings in Florida waters are uncommon. Some observers saw the mantas swimming in large vertical loops, leading them to think that these animals were coming into the shallow reefs to feed on coral spawn.
Mantas inhabit near-shore and pelagic waters, and can grow up to ~14ft in width. They are primarily filter feeders, using large cephalic fins located on the head to help 'funnel' plankton into their mouths.
So, if your diving in the Florida Keys keep an eye out for one of these magnificent animals swimming by - and be sure to record it on your survey!
As you can imagine, on any given day there is a lot that needs to get done at REEF HQ to keep all of our programs running. I want to take a moment to thank Jessica Morris for helping us out during October with miscellaneous,yet crucial tasks in the office. Jessica is a local SCUBA instructor and is eager to help REEF and learn what we're all about. She has already achieved her level 3 experience level and is ready to start surveying when she's not instructing. If any of our REEF members are down in the Key Largo area and in need of a SCUBA instructor or just want to dive with someone who is knowledgable about fish ID, you can reach Jessica at firstname.lastname@example.org. She is also a budding photographer and took the pics of the Dog snapper eating the trumpetfish that is posted on our online forum page at http://www.reef.org/forum. In the future, REEF hopes to provide opportunities for our members to assist us on various projects from their homes. But for now, if you're in the area and want to help out, just let us know and/or stop into REEF HQ for a visit. Meanwhile, we'll look for more surveys and great pics from Jessica this winter.
On Friday, February 1, the Community Foundation of the Florida Keys honored REEF HQ volunteers Audrey and Ken Smith at the 2008 Volunteer of the Year/Unsung Heroes Awards Luncheon in Key West, Florida. Ken and Audrey have been the backbone of REEF HQ in Key Largo for ten years. Their quiet, constant and cheerful help with the unglamorous tasks of building maintenance, data management and administrative work has consistently supported REEF in its mission to actively engage divers and snorkelers in marine conservation. The Ken (“Smitty”) and Audrey team focus on outdoor upkeep and office assistance respectively, contributing their sense of humor and selfless giving to the REEF family and making REEF HQ an inspiring place to work. REEF is grateful and honored to have the Smiths working at REEF HQ. If your travels bring you to the Keys, please drop by and say hi to these important members of the REEF team.
My dive partner and I, both celebrating significant birthdays this year, decided to give ourselves the best gift of all, a dive trip to the Galapagos Islands. The Galapagos Marine Reserve, one of the world's largest, covers approximately 138,000 square kilometers (53,282 square miles). On May 8, 2008, supplied with Paul Humann's Galapagos Fish Identification book and REEF fish survey forms, we set off aboard the Aggressor II for an eleven-day adventure. Our itinerary included diving seven islands (among them Wolf and Darwin), as well as four land excursions, one of them a visit to the famed Darwin Research Station. Fifty-three surveys later, we had identified well over a hundred species, will have to wait for the data report to know just how many species we surveyed. We were lucky enough to see four whale sharks, and an Ocean sunfish. Appearing almost daily were schools of Hammerhead sharks, as well as Galapagos, White-tip, Silky and Reef sharks. Green turtles, three to four feet in diameter often accompanied us and allowed the divers to swim alongside them. In addition, Manta Rays, Spotted Eagle Rays, Mobula, Devil and Golden Cowrays, would suddenly appear from the deep blue below us. We had to be careful when holding onto the rocks in the strong currents not to grab onto one of the well-camouflaged Stone Scorpionfish. A special 110-feet deep dive was made to a cave to find three Red Lipped Batfish, thought to be endemic to the area. Schools of Bottlenose dolphins followed our boat and dove with us often, as did the playful Fur Sealions which would pull on the fins, swim circles around us and come right up to our masks to say “hello!” Flightless cormorants, penguins or marine iguanas would occasionally startle us when least expected under water. We were surprised by the abundances and larger sizes of several fish species. At times, it seemed like we were behind a moving curtain of fish.
Since both of us were fairly new to Pacific diving, we were thrilled even to watch commonly seen fish, such as King Angelfish, Leather Bass, Moorish Idols, Giant Damselfish, Barberfish, Burrito Grunts and the most common of all, the ubiquitous Pacific Creole Fish. The parrotfish and wrasses were also a treat to see; Blue-chins and Bicolor Parrotfish were common and the Harlequin Wrasses, with their distinctive bump on the forehead, seemed to compete for the award in the most original in “pattern and color” combination category. Even though Galapagos diving is best suited for large fish observation, it is also home to many smaller species, among them the endemic Galapagos Triplefin Blennies, Marbled Gobies and Galapagos Pike Blennies, as well as Blue-banded Gobies, Bravo Clinids. Nooks and crannies in the rock walls hid colorful seahorses and even a frogfish. Yellowfin tuna, while not abundant, were seen on many dives and averaged about 3-4 feet long. Unfortunately, their size and market value encourage illegal fishing, since they fetch a high price on some Pacific Rim markets. The land and sea environment of Galapagos is unique, consisting of volcanic islands of varying sizes; consequently, the ocean floor is made up of lava boulders with very little coral. Black coral (golden green in color) was found on some sites. Near shore, most islands had a good amount of green algae, a good source of food for the marine iguanas and green turtles. Galapagos diving is truly unique; its strong, converging currents bring abundant and rich nutrients, providing a perfect environment for the pelagics. We urge you to go see this wonder for yourselves! The Galapagos Islands are designated a UNESCO World Heritage Site. Located approximately 1,000 kilometres off the Ecuadorian coast, within the confluence of three ocean currents, most of the marine and terrestrial fauna is truly unique. Recent efforts at education and outreach to the Ecuadorian community are in direct response to increased illegal poaching within the Marine Reserve that has included shark finning, increased squatting from migrants from the mainland, and an increase in non-indigenous species. such as goats. A recent response from the Ecuadorian Government has enacted a Special Law for protection of the Galapagos Islands. This Special Law provides stricter control over immigration, a quarantine system for combating invasive species, extending the boundary of protection around the islands, limiting property rights and economic activity, and increased national funding for conservation and enforcement - all of which are needed to maintain this unique biosphere for our collective future.
