A new publication in the scientific journal, Coral Reefs, evaluates population genetics of spawning aggregations and the role of juvenile recruitment, from both local and external sources, in sustaining and increasing local aggregations. The study included information from REEF's Grouper Moon Project in the Cayman Islands.
Like many places throughout the Caribbean, Nassau Grouper spawning aggregations in the US Virgin Islands were overfished until their disappearance in the 1970s and 1980s. In the early 2000s, however, Nassau Grouper were found gathering at Grammanik Bank, USVI, a mesophotic coral reef adjacent to one of the extinct aggregation sites, and regulatory protective measures were implemented to protect this fledgling aggregation. The authors of this study addressed two objectives: 1) which factors (local vs. external recruitment) are important in shaping recovery of the USVI spawning aggregations, and 2) the impact of severe past overfishing on the genetic structure of the Gremmanik Bank aggregation. For this second objective, REEF Grouper Moon Project scientists provided genetic samples from individual Nassau Grouper taken from the Little Cayman spawning aggregation, a much larger and less impacted aggregation.
No population structure was detected between the USVI and Cayman spawning aggregations. Additionally, the USVI spawning population showed signs of a genetic bottleneck, typical of greatly reduced populations. These collective results suggest that external recruitment is an important driver of the USVI spawning aggregation recovery. These findings also provide a baseline for future genetic monitoring of the spawning aggregations. The paper, titled "The ups and downs of coral reef fishes: the genetic characteristics of a formerly severely overfished but currently recovering Nassau grouper fish spawning aggregation", was published earlier this month in the March 2016 issue of Coral Reefs. Grouper Moon scientist, Dr. Brice Semmens, was a co-author on the paper.

REEF is excited to announce the launch of a completely redesigned REEF.org website! A unique look, enhanced features, and pages of fresh content ... the address is the same but almost everything else about the REEF website is new. Through enhanced technology and innovative tools, the new Website will enable REEF to more effectively recruit, train and engage divers and snorkelers in the Volunteer Survey Project and REEF’s larger conservation science program. The new REEF.org will also facilitate communication among the REEF community through Member Forums.
The new and very much improved REEF.org is the result of a grant from the Norcross Foundation and a huge amount of work and patience by Ben Weintraub. Ben, a University of Washington Computer Sciences student, created the new site, which includes several new interactive features and a member log-in as well as many of the existing content and features in an updated, easy to navigate and user-friendly site.
Just a few of the features that you will find are:
To get the most out of the new website, you will need to become a registered REEF.org user, so be sure to create a user login profile.
The new REEF.org website will enable REEF to more effectively achieve it's mission to educate, enlist and enable divers and other marine enthusiasts to become active stewards and citizen scientists. The site will also facilitate collaboration with REEF’s existing and new partners and allow our programs to reach a broader audience.
In the coming months, REEF will continue to add new content, and areas still under construction will be completed. All of the REEF staff appreciate your patience in advance as the transition to REEF’s new website is completed.
This is the third major revision to the REEF website. REEF’s online home was originally launched ten years ago in 1997. REEF would like to extend a huge thank you to Ben Weintraub and the Norcross Foundation for making this new site possible, as well as Dr. Michael Coyne (REEF’s primary IT Support Volunteer and developer of the REEF database), and Brice Semmens and Ken Marks (the designers of the previous two versions of REEF.org).
By popular demand, REEF has adapted its classrrom course into a home study DVD course package for beginning "fishwatchers" in the Caribbean, Florida and Bahamas. Click here to read the press release; click here to purchase the DVD course. This would make an ideal holiday gift for your favorite fishwatcher!
Only one space is open for the upcoming Turks and Caicos live-aboard Field Survey, April 19-26th aboard the Aggressor II. We have an ecclectic, well-rounded group of surveyors committed to making this a special trip. Time is running out to join. If you are interested in learning more, please contact Tami at Travel for You (1-888-363-3345) or Joe Cavanaugh at 305-852-0030.
Spaces are also available for the Paul Humann Discovery Tour this summer in Key Largo scheduled June 21-28, 2008. This Field Survey provides a great opportunity for new and seasoned surveyors to interact with renowned marine life author, Paul Humann, and learn from his many years experience, photographing and surveying marine creatures worldwide. Horizon Divers is the dive shop for this trip and also a REEF Field Station. Horizon Divers has worked with REEF on a number of projects over the past several years. Your time on the Discovery Tour will be split between class-work with Paul Humann, learning fish and invertebrate species identification and behavior, and diving multiple sites in Key Largo. Paul will review fish and invertebrate sightings from the dives and incorporate what you are seeing into his classes. Summer diving in the Keys cannot be beat and all the dives will be less than 60 feet depth. There will be opportunities for a night dive and ample time for touring many of the local attractions in the Keys.
June will mark a change at the helm for REEF. We would like to wish Leda Cunningham well in her future endeavors, and welcome Lisa Mitchell as our new Executive Director. Lisa is eager to bring her extensive experience in the dive industry to REEF, as well as her natural passion for ocean conservation.
Lisa’s involvement with REEF almost goes back to the organization’s inception when, in 1993, she was owner/manager of Baskin in the Sun in Tortola, British Virgin Islands. After participating in a REEF Field Survey she immediately went to work involving BVI dive operators in the new program. In fact, because of her enthusiasm, Tortola became the first destination where 100% of the island’s dive businesses became REEF Field Stations. The REEF staff and Board were so impressed that she was asked to bring her organizational expertise and energies to the Board of Trustees in 1995 where she served until leaving Tortola in 1998 to pursue an Executive MBA at the University of Central Florida.
Lisa is a diver’s diver whose life has evolved around the underwater world. She earned her first scuba certification at age 12 while attending Sea Camp in Big Pine Key, Florida where she later became Assistant Scuba Director. During the following years, while gaining experience working at dive resorts in the Florida Keys and with Peter Hughes in Bonaire, she became a Master Dive Instructor and ultimately an SSI Instructor Certifier, and holds a USCG 100 Ton Master’s License. In the process Lisa has made well over 8,000 dives. To honor her many accomplishments Lisa was inducted into the Women Divers Hall of Fame in 2001.
Most recently Lisa has worked as a marketing and business analysis consultant within the dive industry with clients such as Scuba Schools International (SSI), Expedition Fleet Liveaboards, and Dive Dominica.
It goes without saying the REEF staff and Board are delighted to have Lisa back in the fold, and look forward to many prosperous years with such a capable and energetic Captain at the helm.
REEF members and Lisa’s many friends are invited to join us for a “Welcome Back to REEF and the Keys” evening to be held in her honor at 7 PM June 21st, 2008 at the Amoray Dive Resort in Key Largo.
Earlier this month, the Dive Equipment and Marketing Association (DEMA) held its once a year industry-wide, international trade show in Las Vegas. As part of the show, which attracts over 10,000 industry professionals and businesses, DEMA recognized the importance of the recent lionfish invasion into the Atlantic and asked REEF to present four show-sponsored talks for attendees and members.
DEMA organizers also provided premium space at the show for an aquarium display and informational exhibit on the issue. REEF responded by providing an all-star cast of speakers and experts including Lad Akins (REEF), Andy Dehart (National Aquarium in DC), Chris Flook (Bermuda Aquarium) and Stephanie Green (Simon Fraser University). The talks were very well attended and the response from industry leaders was extremely positive. Marine Life artist, Ron Steven - better known as Rogest, was also on hand to sign special edition lionfish prints that he donated in support of REEF's efforts. During one seminar, Ron stood up to say that he never thought he would be encouraging divers to remove fish from the environment he works so hard to protect, but based on what we are seeing we should get rid of all lionfish (in the Atlantic). Similar sentiments were expressed by all who attended the talks. In addition to the talks, the 250 gallon aquarium set-up donated by ATM Aquariums in Las Vegas was a big hit. Ten lionfish were on display and provided excellent opportunities for in-depth discussions at the booth.
Next steps for work within the dive industry as outlined at the DEMA show are to work with inland dive operators to organize educational and data gathering lionfish projects and to work with island governments and on-island dive operators to conduct week-long workshops including education/outreach, monitoring, collecting/handling techniques and market development themes.
REEF will be leading its next week long in-country workshop in the Turks and Caicos in November and the next diver oriented project with Dive Provo January 17-24. For more information on how to organize a REEF-led lionfish project or to host a REEF workshop, please contact Lad Akins, Director of Special Projects, Lad@reef.org, (305) 852-0030. To sign up for the Turks and Caicos project with Dive Provo call our REEF travel specialist at 877-295-REEF. To find out more about REEF's efforts on lionfish, visit the REEF Lionfish Research page.

Working in close partnership, REEF, NOAA, and the USGS, have just completed the first field guide to non-native fishes in Florida. The 120 page publication documents the occurrences, identification and ecology of more than 35 non-native fish species found in Florida waters. Detailed sightings maps, notes on similar appearing species and information on native ranges are included. The goal of the publication is to provide a single source, field ready guide for enforcement as well as a reference for researchers and educators to aid in early detection and removal of non-native marine fish. The red lionfish, which was first documented off Florida in 1985, provides an example of what can happen once an invasive fish species becomes established. Lionfish are now widespread along the southeast US and parts of the Caribbean, preying upon ecologically-important native species such as fishes and crustaceans. REEF continues to conduct training, outreach, and field studies to limit the spread and impact of lionfish on native western Atlantic reefs.
The illustrated guide was published as a NOAA Technical Memorandum that is available online (http://fl.biology.usgs.gov/Marine_Fish_ID/index.html). 1,300 copies were printed and are being distributed to key local, state and federal agencies. The on-line edition guide will be continuously updated with new records and reports.
Divers and snorkelers can report non-native species that are seen underwater at REEF's Exotic Species Sighting Page.
One of nature’s most spectacular underwater wonders is the annual coral spawning, when many of the reef’s corals and other animals, cued by late summer’s full moon, synchronize their spawning. Our summer REEF Trips, to Key Largo August 26 - September 2 and Bonaire September 25 – October 2, are scheduled around the projected coral spawning for those areas. Join like-minded underwater naturalists and combine fishwatching with a chance to see this exciting event.
Ned and Anna DeLoach will host a one-of-a-kind, late August trip at Amoray Dive Resort, centering on Key Largo’s annual Coral Spawning. In addition to slide and video presentations about marine life spawning behavior, the couple will lead a week of diving with emphasis on the nights that corals are most likely to spawn. Laurie MacLaughlin, Resource Manager from the Florida Keys National Marine Sanctuary, will update us about her ongoing coral spawning research and describe coral spawn collecting methods. Ken Nedimyer, founder of the Coral Restoration Foundation, will speak about growing coral for restoring reefs and will escort the group to his famous coral nursery, where participants will have the opportunity for hands-on work. Day dives will provide the opportunity to hone fishwatching and survey skills and a special dusk dive is scheduled to observe fish spawning behavior and the evening gathering of hundreds of Midnight and Rainbow Parrotfishes. A rare opportunity for anyone who loves nature!
Jessie Armacost, author of the original Bonaire Diving Made Easy, and long-time REEF instructor will lead the late September trip at Buddy Dive Resort in Bonaire. Few dive sites in the world can provide 100 fish species on a single dive - Bonaire is one of these special places where you can make that “Century Dive”. Jessie’s seven years of teaching fish ID in Bonaire makes her uniquely qualified to help you add fish species to your lifelist or gain the skills to move you up to your next surveyor level. Bonaire’s exceptional shore diving and easy boat diving give you access to a wide range of habitats with a chance to see everything from clingfish to Bonefish. We’ve scheduled this year’s trip to coincide with the Southern Caribbean’s annual coral spawning, so you’ll have the chance to watch fish by day and view this great natural history event at night.
For more information on either of these projects, visit the REEF Trips webpage - http://www.reef.org/fieldsurveys/schedule. To reserve your space please contact our dedicated REEF Travel Consultant at 1-877-295-7333 (REEF), or you can e-mail REEF@caradonna.com.
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 Flo Bahr (REEF member since 2001). Flo lives in Kihei, Hawaii, has conducted 186 REEF surveys, and is a Level 5 Expert surveyor. Along with Rick Long and Liz Foote, Flo helps organize the Fish Identification Network (FIN) on Maui. FIN provides an opportunity to join friends and fellow fish lovers in exploring the coral reefs of Hawaii. Maui's original FIN founders, Mike and Terri Fausnaugh, have since started FIN on Oahu. There are monthly, sometimes weekly, dives at various beaches. At every event, volunteers set up a REEF station with survey materials and identification reference guides in an attempt to lure in new afishionados! Here’s what Flo had to say about diving with REEF:
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
Way back in 2001, Liz Foote introduced me to REEF. She was so enthusiastic and knowledgeable about the ocean and fish that it encouraged me to learn more. Being relatively new to living on Maui, I had a lot to learn. Fish card in hand, I tried to identify and learn at least two new fish each time I went snorkeling or diving. I had a screensaver on my computer that flashed fish pictures and their names, the latest fish identification books and friends to debrief with after snorkeling and diving.
What is your favorite part about being a REEF member?
The friendships I have developed and “talking fish” with friends has become my favorite part of doing REEF surveys. We even started a club called FIN, for Fish Identification Network, and we meet once a month for REEF surveys, socializing, and FOOD. The club is open to anyone who has an interest in fish, and we have a nice, flexible group. New people swim along with more experienced surveyors, and we all have fun after with eating and talking about what we saw that day.
In your opinion, what is the most important aspect of REEF’s projects and programs?
The fun and friendships are great, but the REEF surveys are so valuable to scientists, students, and other avid fish folks. There is just not a wealth of information about what fish are where and in what quantities, so our data can be helpful in determining the health of our declining reefs and can also give swimmers an idea of what might be seen in different areas.
What is the most fascinating fish encounter you’ve experienced? Is there a fish you haven’t seen yet diving, but would like to?
There are so many cool and surprising things to see in the ocean. Just last week, at Maonakala while snorkeling, we saw a Coronetfish taking a ride on a turtle. A couple of months ago while diving at Wailea Point, we saw a turtle with a strange lump on its back that turned out to be a resting Flowery Flounder. As for what I want to see -- a seahorse! Recently we were diving Wailea Point because of reports of seahorses being seen by a few divers. We searched and searched while diving in just 10-15 feet of water. We couldn’t find them but will keep on looking until we do. It will be so cool when I find a seahorse and get to add it to my survey!
