World-wide declines in shark and ray populations have prompted the need for a better understanding of their patterns of distribution and abundance. While much of the focus has been on the larger species of sharks, little attention had been paid to the most frequently sighted elasmobranch species in the greater-Caribbean, the yellow stingray (Urobatis jamaicensis). Despite being relatively common and listed as Least Concern on the IUCN Red List, little was known about the status of this species. Unfortunately, it has been quietly declining. Dr. Christine Ward-Paige and her colleagues at Dalhousie University worked with REEF's Director of Science, Dr. Christy Pattengill-Semmens, to examine the status of yellow stingray. The results of this study were recently published in the scientific journal, Environmental Biology of Fishes. Click here to read the paper.
The study used 83,940 surveys collected by REEF surveyors in the western Atlantic. In total, yellow stingrays were observed on 5,658 surveys (6.7% sighting frequency) with the highest occurrence in the regions surrounding Cuba. Overall, sighting frequency declined from 20.5% in 1994 to 4.7% in 2007. However, these trends were not consistent in all regions. The strongest decline occurred in the Florida Keys, the most sampled region, where trends were similar among all areas, habitats and depths. Possible explanations for these changes include habitat degradation, exploitation (this species is collected for medical research and the aquarium trade), and changes in trophic interactions. The results of the study suggest large-scale changes in yellow stingray abundance that have been unnoticed by the scientific community. This study also highlights the value of non-scientific divers for collecting data that can be used to understand population trends of otherwise poorly studied species.

Changing Seas, an original production of Miami’s public television station WPBT2, will host a live online screening event of Alien Invaders, the series’ latest episode focusing on the lionfish invasion in the Caribbean and Western Atlantic. Alien Invaders will be screened live on the Changing Seas website (www.changingseas.tv/webcast) on Thursday, June 2nd at 7:30 p.m. EST. During the screening, dive enthusiasts will have the opportunity to join an online chat with producers and the experts featured in the program. REEF's Lad Akins and researcher Stephanie Green will be be online to answer questions live during the event.
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 feature Patricia Broom (REEF member since 2004). Pat is a member of REEF's Advanced Assessment Team in the Tropical Western Atlantic and has conducted 277 surveys in three of REEF's regions, including some of the first in our newest region, the South Pacific. Here's what Pat had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
About ten years ago while reading a favorite dive magazine I noticed an announcement about an introductory fish identification trip sponsored by REEF and led by Paul Humann. The love of REEF was born!! I responded to the advertisement, encouraged my brother to join me and attended that Field Survey trip. We joined a group of equally dedicated divers eager as we to learn about fish and how to identify them. Paul was a great teacher, very patient and concerned that we not only learn about fish but care about them and the ocean we love.
If you have been on a REEF Field Survey, where and what was a trip highlight?
One of my most memorable surveying moments occurred that week on Paul's trip. On a night dive of a very old wreck with exposed wooden beams I saw my first queen parrotfish in their nighttime cocoons. Each parrot fish occupied a space between two beams framed by basket stars in full bloom. It was a magical sight. I try to take two or three REEF trips a year, they are a great way to learn more and dive with great people. In addition to the regular ID trips, I have really enjoyed the REEF Behavior Trips that are led by Ned and Anna DeLoach. It really completes the learning experience! It is a beautiful sight to watch damselfish guard their algae gardens from predation, observe cooperative hunting, or watch a three foot Midnight Parrotfish at a cleaning station with open mouth and flared gills.
What inspires you to complete REEF surveys?
Prior to that introductory course, I had been diving the Caribbean for twenty plus years. I witnessed the decline in fish numbers and species as well as reef degradation and wondered how many more years I could dive before there was nothing to see! REEF offered me a reason to continue diving, now there was opportunity to give back and enjoy diving again.
Do you have a favorite local (or not) REEF field station or dive shop?
I have found great enjoyment in Cozumel at the REEF Field Station at Aqua Safari, led by Sheryl Shea. She is a gifted teacher determined to make advanced assessment divers of all of us! It just so happens a few of my favorite fish are in Cozumel, the Splendid Toadfish, Sargassum Triggerfish, and Cherubfish, to name a few.

REEF is once again partnering with CEDAM International to support an educator to participate in one of our REEF Trips. The selected Lloyd Bridges Scholar will join Paul Humann on the Little Cayman Field Survey in July 2013. The goal of the scholarship program is two-fold: One, to have educators experience the wonders of the underwater world and then be able to share these wonders with his or her students or constituents. Two, to have these inspired individuals go out and do what they can to help protect one of the world’s most fragile ecosystems. To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization. More information and application information is posted on the CEDAM website.

We are proud to announce our 2013 Volunteers of the Year, Carlos and Allison Estapé. Carlos and Allison joined REEF in 2008, and collectively, they have conducted 108 surveys. They call the Florida Keys home. As Tropical Western Atlantic REEF Advanced Assessment Team members, skilled lionfish hunters, expert underwater photographers, and PADI Open Water Scuba Instructors, this diving duo is instrumental to REEF’s fieldwork conducted in the Upper Florida Keys and they are avid REEF ambassadors. Most recently, they have raised interest in the 100 Fish ID Challenge, or "Century Dive", in the Keys, whereby a REEF surveyor finds at least 100 species of fish on one dive (their quest even ended up in the Miami Herald newspaper). Here's what Carlos and Allison 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?
In 2008, we moved to the Keys permanently and we were looking for people with similar interests. What a great find! We started attending the monthly REEF Fish and Friends lectures and participated in REEF Lionfish Derbies. From there, our participation continued to grow as we got involved with the interns and the 100 Fish Challenge.
What inspires you to complete REEF surveys?
Carlos- "For me, surveys have evolved into an underwater treasure hunt. There is a great quote that says “The larger the island of knowledge, the longer the shoreline of wonder” R.W. Sockman. And this directly applies to fish surveys. When all you know are 100 species you try to pigeonhole everything you see into that knowledge base, but as I have delved deeper into all the real possibilities I question even what appears to be obvious. A few days ago, Allison pointed out a solitary fish on a deep mooring line. It appeared to me to be an Orange filefish, a species I only see on rare occasions and needed a better photograph of. Only after seeing the image on the computer back at home did I realize I had just photographed the first and only Unicorn Filefish (Aluterus monoceros) I have ever seen!
Allison - "I completely agree with Carlos on the surveys being an underwater treasure hunt. It is always exciting when you identify a new fish and/or see a very rare fish. I’ve greatly enjoyed adding to the REEF database and expanding the number of species sighted on our favorite dive sites. When we realized that there was the possibility of seeing over 100 species of fish on one dive at Alligator Reef, that really motivated us to not only expand our ability to identify with certainty more fish species, but it also motivated us to get out and do 2 ½ hr dives to see just how many species we could identify on a dive. My personal best was 116 fish identified and we have had a great time taking the REEF Interns and other fish ID enthusiasts to Alligator Reef so they can attempt to identify over 100 species. So far, 12 divers have achieved the 100 Fish ID Challenge, and we are hoping that many more take up the challenge. Doing the 100 Fish ID Challenge has really taught me where to look for different species of fish, and has really re-invigorated my diving enthusiasm – I spend time in the grass flats, sand, and rubble areas looking for the small fish I never paid any attention to prior to doing the surveys.
What is your favorite part about being a REEF member?
The camaraderie, hands down! We have especially enjoyed our time with the interns when we take them out on our boat and show them some of our favorite dive sites. The friendships we have made with the REEF team and members, the fun of diving with other fish enthusiasts, and the sense of excitement and accomplishment we achieve together when we do Field Surveys and attempt the 100 Fish ID Challenge, has made our participation in REEF one of our most satisfying experiences.
If you had to explain REEF to a friend in a couple of sentences, what would you tell them?
Carlos - "REEF is an organization of people driven by their passion of the sea with the goal to protect and document life in the oceans."
In your opinion, what is the most important aspect of REEF’s projects and programs?
Carlos - "Education. You only love what you care about, only care about what you know and only know what you are taught.
Allison - "I also believe the scientific research and data that REEF volunteers collect is making a difference in the management of our marine ecosystems/fisheries. The Lionfish removal/derby data is enabling marine park managers to make scientific choices on how to manage the invasive species, and the REEF survey database allows non-scientists to participate in collecting data that scientists use.
Do you dive close to where you live, and if so, what is the best part about diving there?
We have the Florida reefs thirty minutes away by boat by design. I was certified in 1978 and my first dive was on Pickles reef. Recently we have been on a quest to photograph as many species as possible listed on a survey done by Dr. W. Starck back in the 1960’s. Over a period of ten years he found over 500 species in our own backyard! Over 300 of those are within the safe diving limits and so far we have photographed 225 of them including a few he never found!
Do you have a favorite local (or not) REEF field station or dive shop?
Islamorada Dive Center (IDC) out of Windley Key in Islamorada. Great attitude and service. They always put a dive guide in the water with you for no extra charge. We have become close friends with everyone there.
What is the most fascinating fish encounter you’ve experienced?
Carlos - "The one and only time I was in the water with a Whale shark in the Maldives. We had been motoring for hours looking for one without success and finally the crew gave up and put us in the water anyway. Within minutes a shadow blocked the sun and when I looked up there it was! A juvenile “only” about twenty-five feet long! We swam with it for a few minutes and then it was gone like it had never been there. When I dive I always try to remember to look up now and then."
Allison - "The time we found a 12ft sawfish while diving on the Eagle Wreck in the Florida Keys. The sawfish was laying on the sand in 110 ft of water and looked like a parked submarine. It was flanked by 2 large remora. When we approached it, it pushed up off the bottom in a big swirl of sand and slowly swam away. It was a spectacular sighting of a very rare animal. On that same dive we saw a spotted eagle ray, hawksbill turtle, and many schooling fish. That dive goes down in the memory books as one of our best."
Do you have any surveying, fishwatching, or identification tips for REEF members?
Carlos - "Take a camera with you and if you can afford it add an external strobe even to the simplest of point-and-shoot cameras. I cannot tell you the “finds” I have made once I have downloaded and reviewed the day’s photos. A great example of this was reviewing some of Allison's photos that she had taken at Alligator ledge of a Colon Goby. Lying next to the goby is a three inch Saddled stargazer! She didn’t realize it was there when she snapped the photo."
Allison - "A camera, or a buddy with a camera is a must. The more I learn, the less I “know”. You have such a short amount of time to ID fish and so many species are similar that having a camera really makes a difference in identifying an Almaco Jack vs a Lesser Amberjack, and when it comes to the tiny triplefins – a photo is the only way I know whether I got the ID right.
Please join me this year by giving a gift to REEF this holiday season! I want to thank all those who have been so generous and have donated already. If you haven’t given yet, we are still a long way from our goal. Your donation this winter is critical so we can continue protecting marine species all year. Click here to donate now.
Examples of REEF’s important work that directly benefit marine species include:
As you can see, REEF works hard all year to ensure our oceans are healthy and the creatures within are protected. As my personal thank you for donations $250 or more, I will send you a limited-edition, signed print of a Goliath Grouper aggregation. Check out this webpage, www.REEF.org/impact, describing this rare photo opportunity!
We have a SIX great Fishinars planned for July. These hour-long sessions enable you to learn and have fun from the comfort of your living room. We hope you will join us - it's free for REEF members. Check out the full schedule and links to register at www.REEF.org/fishinars.
Thanks to a grant from The Russell Family Foundation, we are in the middle of a year-long initiative to actively engage new REEF surveyors in the region and to provide incentive to our existing surveyors to stay active and move up through the ranks of the REEF Experience Level system. We have teamed up with PNW REEF instructor, Janna Nichols, to coordinate a series of free training workshops throughout Washington and Oregon. These seminars will cover the Introductory REEF Fish Identification training, the REEF Pacific Northwest Invertebrate Identification training, and a NEW Advanced Fish Identification training program. Visit the Pacific Northwest Critter Watchers Webpage to see a complete list of classes. The project will also support a series of REEF survey day trips on area dive charters that will be open free of charge to current REEF surveyors who are actively conducting surveys and interested in advancing their REEF experience level. Ten active REEF surveyors recently participated in the first such opportunity - survey dives at two new REEF sites in the San Juan Islands, Washington earlier this month. In addition to conducting REEF surveys. The great news is that everyone on the trip who was eligible to move up one experience level did so! A big congratulations goes to Pete Naylor and Mary Jo Adamas, REEF's newest Pacific Advanced Assessment Team Level 5 members, and the rest of the gang who successfully passed the Level 2 or Level 3 exam.
We greatly appreciate the funding support of The Russell Family Foundation. This project will enable REEF to actively engage divers in marine conservation through support and enhancement of the REEF Volunteer Survey Project in the Pacific Northwest. Traditionally, divers and snorkelers have not received much more than a cursory introduction to underwater ecology or marine life identification. Even after years of experience in the water, most divers are able to identify only a handful of the marine life they see during their dives. REEF introduces marine enthusiasts to the incredible diversity of fishes and other wildlife found in local waters as well as the identification resources and survey methods needed to document these species. Active REEF surveyors advance through five experience levels (Novice: 1-3 and Expert: 4-5), based on the number of surveys completed and passing scores on comprehensive identification exams. While 536 volunteers have conducted surveys in the Pacific Northwest as part of the REEF Fish Survey Project, there are currently only twenty-eight members rated as Expert surveyors. However, expert level volunteers have conducted approximately one-third of all surveys submitted to date. It is clear that as volunteers improve their skills, they are more likely to stay actively involved in data collection.
