Long-time REEF supporters, Les and Keri Wilk of ReefNet, recently discovered and photographed a distinctively marked population of the Greenbanded Goby, Elacatinus multifasciatus, on the island of Utila, Honduras. The population was distinguished by a prominent red stripe across the cheek that is not found on other populations of Greenbanded Gobies, as well as more numerous green bars on the body. The Wilks contacted Dr. Benjamin Victor (coralreeffish.com), a reef fish taxonomic expert, who conducted a regional genetic comparison of Greenbanded Gobies to evaluate hidden diversity within this colorful reef fish. As part of the study, the REEF database was used to document the current geographic range of the species. Dr. Victor's results identified the unique looking fish to be a separate species that is now called the Redcheek Goby (E. rubrigenis). He also discovered that, based on genetic results, Greenbanded Goby along coastal Panama, despite looking just like others in the species complex (i.e. a cryptic species, distinguished mainly by differing DNA sequences), are a distinct species that will now be called Panamanian Greenbanded Goby (E. panamensis). The study was published last month in the Journal of the Ocean Science Foundation.
The new species, the Redcheek Goby, replaces the Greenbanded Goby on the island of Utila and has not been sighted at any other location, potentially one of the smallest ranges reported for a Caribbean reef fish. With few exceptions, coral reef fishes have pelagic larvae that spend weeks to months developing in off-reef waters. As a result of this high dispersal ability, most Western Atlantic reef fish species have geographic ranges throughout the Caribbean Sea and adjacent areas. Endemic marine species (those only found in a given region or location and nowhere else in the world) are generally uncommon in the western Atlantic region. Furthermore, many of these widespread species show little, if any, variation in their genetic patterns between areas, particularly within the bounds of the Caribbean Sea with its many stepping-stone islands. Nevertheless, some groups of fishes, presumably those with more-restricted larval dispersal and strong local selection, show interesting patterns of endemism, genetic structure, and cryptic speciation within the region, for example among the Elacatinus cleaning gobies (e.g. Sharknose, Cleaning, Neon, Yellowline, etc.). Those reef fish taxa that contain cryptic species can provide valuable insights into the processes of speciation and the biogeographic history of the region, but also seriously challenge the traditional species concept. The results of Benjamin Victor's study highlight these challenges.
REEF is proud to be able to contribute to scientific studies such as this one. We are also thrilled that fishwatching by amateur non-scientists like our Fish Survey Project volunteers has been elevated beyond just a hobby, and is increasing the state of knowledge about reef fish diversity.

Field Surveys – Eighteen REEF members joined Drs. Christy and Brice Semmens earlier this month on a Field Survey to the Sea of Cortez aboard the Rocio del Mar live-aboard. The team conducted over 300 surveys in 20 locations around the Midriff Islands, many of which were new to the REEF database. It was a great trip, with 130 species of fish found, beautiful topside scenery, and pods of sperm and pilot whales! Find out more about REEF Trips.
Lionfish Derby – The second of three lionfish round-ups in the Florida Keys was held last week off Marathon (FL). During this one-day event, several teams participated to collect this voracious predator off local reefs. The third derby is scheduled for November 13 in Key West. Find out more about REEF’s Lionfish Program.
REEF proudly awards our 2010 Volunteer(s) of the Year award to Donna Brown and Liz Foote. Donna and Liz both live on Maui in Hawaii, where they have been active in REEF since 2001 when we expanded the Fish Survey Project to the Hawaiian Islands. Donna has been a REEF member since 1994 and Liz since 1999. Both are members of the Hawaiian Islands Advanced Assessment Team and collectively have conducted 361 surveys. Donna and Liz were instrumental during the expansion to Hawaii. They provided technical assistance in the development of the survey and training materials and supported a growing network of local REEF surveyors. Through the years, these volunteers served as incredible ambassadors of the program, generating a core group of dedicated REEFers, who have in turn have carried the REEF torch. The Fish Identification Network (FIN), a local REEF group, grew out of their efforts. 10 years and 10,000 Hawaii surveys later (as of January 2011), REEF is going strong on the islands. Donna and her husband George have also been a part of the South Pacific expansion team, and participated in two REEF training trips to American Samoa. Both Donna and Liz continue to be very active in many other regional marine environmental issues in addition to their REEF activities.
REEF volunteers are the cornerstone of the organization. Without this dedicated corps, our marine conservation programs would not exist. They are central to the REEF Volunteer Survey Project, in which over 14,000 divers and snorkelers have submitted their sightings information to the largest marine life database in the world. REEF volunteers conduct important marine conservation research alongside scientists as part of the Grouper Moon Project and the Lionfish Invasion Program.
The REEF Staff and Board of Trustees extend a big thank you to Liz and Donna and congratulate them on all of their marine conservation efforts and great work on behalf of our organization!
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 Kenny Tidwell (REEF member since 1998). Kenny is a member of REEF's Advanced Assessment Team in the Tropical Western Atlantic and has conducted 291 surveys. Here's what Kenny had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I had been scuba diving for many years and after several hundred dives, I was honestly getting a little bored with what seemed to me as basically the same stuff on every dive. Little did I know I had been blindly swimming by some pretty amazing stuff that I didn’t even realize was there! I was lucky enough to take a dive trip to Bonaire in 1993 where I first met Jerry Ligon who is a naturalist in the area and inspired me to become a fish watcher! I immediately bought Paul Humann’s Caribbean fish ID book and made it my mission to learn something new on every dive. Around that same time, I started reading about REEF in dive magazines and liked what I saw about the organization's mission and activities. I had long wanted to go on one of their field survey trips and finally signed up along with my wife, Vickie, to go on my first REEF Discovery field survey trip to Puerto Rico led by Paul Humann. After that first trip, I was hooked and would rather dive with other REEF divers than do any other dive activity. I had finally figured out why I was getting a little bored with scuba. REEF really breathed new life into my diving!
If you have been on a REEF Field Survey, where and what was your trip highlight?
I have been on about one or two field survey trips each year since I started diving with REEF. In addition to my first Discovery trip to Puerto Rico, I have been to the Sea of Cortez, Lee Stocking Island, Bonaire, Little Cayman, a lionfish research trip to Bahamas, and several times to Cozumel. The highlight of each trip was the opportunity to meet and learn from other REEF divers who share a similar mission.
What inspires you to complete REEF surveys?
I strongly believe in the mission of the organization and sincerely want to contribute something from my diving efforts. It has been a real challenge to me to try and learn as much not only about fish ID, but also about fish behavior. I am just like a birder who wants to find that new species to add to their list. It is a real thrill to me to add something new to my list and to find something I have been looking at in the books, but haven’t yet seen in the ocean!
What is your favorite part about being a REEF member?
Going on field survey trips and interacting and learning from other divers. I have learned a lot and have met some wonderful REEF members who have really inspired me, including Paul Humann, Ned and Anna DeLoach, Sheryl Shea, Franklin and Cassandra Neal, Lad Akins, Brice and Christy Semmens, Judie Clee, and many many others! I actually enjoy the classroom time almost as much as the diving itself! I only wish I had hooked up with REEF sooner! I have also used the opportunity to invite other divers and snorkelers that I meet on trips outside of REEF to tell them about the organization and invite them to participate. Each time I am on a dive boat and have a survey slate in my hand, it always seems to invite an inquiry as to what I am doing? I use that window of opportunity to try and inspire new fish watchers. We have given away many of the waterproof underwater fish ID books to divers and snorkelers that we meet in order to get them more interested in learn the amazing variety of marine life around them that most seem to not even recognize that they are there, much less know what they are looking at.
Do you have a favorite local (or not) REEF field station or dive shop?
All of the REEF field stations that I have visited are great, but if I had to pick one, I would choose Aqua Safari. I first dove with them in 2005 about 5 wks after Hurricane Wilma struck Cozumel. That is when I had the opportunity to meet Sheryl Shea and the rest of the staff at Aqua Safari. I have been back for every field survey there since that time with the exception of last year when I was in a severe accident that curtailed my diving for quite a while. Sheryl is a GREAT teacher and a real inspiration to dive with as is all of the staff at Aqua Safari. Tracy Griffin is also a great teacher and will be leading the trip this year. There are places in the Caribbean that you can count on finding more species to log on your survey, but the field survey trip to Cozumel always is a lot of fun.
In your opinion, what is the most important aspect of REEF’s projects and programs?
Increasing the awareness of the fragility or our marine environment I think is critical to REEF’s mission. The contribution of an enormous amount of data to document declining fish populations is valuable, which changes how people view the fragile nature of the environment and ultimately affects public policy to protect those resources. The lionfish project is extremely important in addressing an issue that is rapidly decimating fish populations on reefs where they have established themselves and in finding solutions to this problem is critical to protecting the reefs.
Where is your favorite place to dive and why?
Usually the last place that I have visited, but if I had to pick one it would probably be Bonaire or Little Cayman. You can’t beat the number of species and abundance of fish life in Bonaire, but I really like the island of Little Cayman for its beauty and lack of development and it also has some of the best diving in the Caribbean along Bloody Bay Wall. I have been to each location several times and would go back to either in a heartbeat.
Nine REEF members joined REEF Director of Science, Dr. Christy Pattengill-Semmens, for a Field Survey week in Nevis last week, kicking off the 2012 REEF Trip season with a bang. The group stayed at Oualie Beach Resort on Nevis and dove with the on-site dive operator, Scuba Safaris. Over 120 surveys were conducted, which is a great addition to the REEF database for this region (prior to this trip, there were only 7 surveys from Nevis). Each afternoon, the group would gather for a few hours to discuss the day's sightings, review images and video, and enter survey data. Everyone really enjoyed the diving. Fish diversity and abundance was relatively high, and during the week the group documented just under 200 species of fish! Some of the more rare and exciting finds included bluestripe dartfish, mimic blenny, dwarf sand perch, flying gurnard, striped croaker, Atlantic spadefish, and nine line goby. Participants ranged from brand new REEF surveyors to a few of our most experienced, and a great time was had by all. Check out the online album posted here.

Washington Fish and Wildlife Commission are currently reviewing existing size limits, bag limits, and fishing season for cabezon in Puget Sound waters. Cabezon are bottomfish that inhabit rocky areas. They can measure up to 30-inches and weigh up to 25 pounds. REEF data from the Puget Sound, representing 11,646 individual survey from 427 sites throughout the region, were used as part of the Commission's review to identify trends in cabezon abundance in Puget Sound. WDFW researcher, Dayv Lowry, conducted the analysis. According to the REEF data, there is a decreasing trend in the frequency of detection of cabezon between 1998 and 2012. This trend is most pronounced in the central Sound from Seattle to Tacoma. The majority (81%) of cabezon sightings in the REEF database are from Edmonds Underwater Park, a long-time marine reserve north of Seattle. At Edmonds, cabezon appear to have decreased sharply since 1998. These findings were included in a report submitted the Commission (report available online here). Earlier this year, the Commission voted to reduce the daily catch limit of cabezon to one fish and prohibit the retention of cabezon measuring less than 18 inches in length. They are currently reviewing the fishing season length and are meeting in June.
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 Mike Delaney, one of REEF's earliest Pacific Northwest volunteers. Mike has been a REEF member since 1999, and has conducted 433 surveys. He is a member of the PAC Advanced Assessment Team, and he has the distinction of conducting the 20,000th REEF survey in the Pacific region back in 2011 (see story). Here's what Mike 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?
I heard about REEF through the Living Oceans Society’s Living Reef Project. I began my training course with Susan Francis and Dana Haggarty in 1999 and I was part of the LOS’s pilot PNW Invertebrate Survey Project. To improve my identification skills of PNW species, I was mentored by Donna Gibbs and Andy Lamb of the Vancouver Aquarium. In an effort to gain more buddies to survey with, I began organizing Great Annual Fish Counts and teaching the REEF curriculum. Fish watching, conducting surveys, and REEF became a passion.
If you have been on a REEF Field Survey, where and what was your trip highlight?
I had the opportunity to visit one of my favorite dive destinations Hornby Island and take part in the 2012 Field Survey lead by Janna Nichols and hosted by Hornby Island Diving . I have been to Hornby Island numerous times, and it is always a treat because it offers a great variety of marine life. During the trip, the group was able to dive a site that is not visited frequently and was inhabited by large schools of rockfish, lingcod, cabezon and colourful invertebrate life that adorns the sandstone walls. Another great thing about REEF is the ability to learn and survey in other regions, whether it is a REEF trip or not. I have had the opportunity to complete surveys in the TWA and in the TEP!
In your opinion, what is the most important aspect of REEF’s projects and programs?
The concept of scuba divers as citizen scientists is inspiring. As an individual we can contribute to a greater good: the understanding of the ocean and its inhabitants! As ocean explorers we can collect data and know that the information collected is being used to support science initiatives to protect the oceans.
Do you dive close to where you live, and if so, what is the best part about diving there?
In Vancouver we are fortunate to have numerous local dive sites to visit and most of my surveys are completed in the rich emerald waters of British Columbia. One of my frequented dive sites is Whytecliff Park and I had the unexpected surprise of completing the 20.000th PNW survey at the same site in which I conducted my very first REEF survey! Whytecliff is a great site because you never know what critters you might come across. Whytecliff Park offers wall diving with lots of sponges and a sandy bay with eel grass beds for poking around on your safety stop.
Do you have a favorite local (or not) REEF field station or dive shop?
In 2006 I began working at The Edge Diving Centre, which was quickly registered as a REEF Field Station, one of the first in British Columbia! I have been able to introduce numerous new divers to the REEF survey project!
What is your favorite fish or marine invertebrate? Why is it your favorite?
I have an affinity for our local PNW Rockfish! Ray Troll’s Rockfish poster adorns my wall as a tribute to my love of rockfish. Discovering something out of the ordinary always gets me excited. In 2008, I spotted a lone Black Rockfish at Whitecliff Park, which is notable because Black Rockfish have just about all been extirpated from Howe Sound. In 2009, also at Whytecliff Park, I confirmed a Blue Rockfish sighting, a species known mostly only from the outer coast. Sharks are my an all time favorite! I had the chance to visit and survey the Socorro Islands with it’s great number of shark species that inhabit the islands. Always awesome to dive with big sharks!

REEF has just completed our final assessment report for our five-year Wellwood Restoration Site monitoring project. Before I share some results from our study, let me give you a little background information and please visit our website to view our full report http://www.reef.org/programs/monitoring/wellwood. The M/V Wellwood, a 122-meter Cypriot-registered freighter, ran aground on August 4, 1984, on Molasses Reef off Key Largo, Florida, part of the Florida Keys National Marine Sanctuary (FKNMS). The ship impacted the reef’s upper fore reef and subsequently remained aground for 12 days. The grounding destroyed 1,285 square meters of living coral reef and injured 644 square meters of coral reef framework. Prior to the grounding, the area was a transition zone with high relief coral formations. The grounding transformed the area into a flattened, barren pavement covered with coral rubble.
The study area of this project included a portion of the grounding area that is being restored and two adjacent reference sites. The Restoration site surveyed included restoration modules and contiguous low profile hardbottom areas adjacent to and in between the restoration modules. Nearby high profile reef, ledges, and undamaged/unrestored reef were not included as part of the Restoration Site. A north and south undamaged reef area were both used as two control sites to compare fish sighting data between the Restoration area and the natural (control) reefs.
REEF’s study focused on fish assemblages and not the coral and invertebrate communities. A team of Advanced Assessment Team REEF Experts conducted Roving Diver Technique (RDT) surveys in addition to belt transect surveys on the Wellwood restoration site and two adjacent natural reef sites seven times during Year 1. The team visited the sites once prior to restoration (May 2002) and 13 times after restoration was completed, monthly for the first three months, quarterly for the following year and semi-annually thereafter. An average of 12 surveys of each survey type was conducted during each survey effort. While REEF surveyors used the RDT surveys to collect sighting frequency and abundance data on fishes over all three reef areas, the belt-transect method was used to collect density and biomass data on fish taxa. These two methods used together give us a snapshot of how the restoration site is recovering in terms of fish assemblages as compared to the two non-impacted, adjacent reef areas.
Obviously, the most notable observation a diver makes when diving on the Restoration site is one of just how long it takes coral reefs to recover after devastating ship impacts. The Restoration site shows little resemblance to the surrounding non-impacted reef sites. The areas surrounding the Restoration site are high relief reef areas dominated by reef building corals with some very old colonies of Star coral (Monastrea annularis) and Elkhorn coral (Acropora palmata), old to the tune of thousands, not hundreds of years old. Age is important here since it takes a long time for coral colonies to rebuild structure and relief that attract different fishes over time. The smaller overall fish populations and absence of many species of fish on the damaged site are both conspicuous and the lack of coral structure makes it easy to destinguish the Restoration area from the surrounding reefs even 23 years after the initial ship grounding. However, there are signs that fishes are very slowly recruiting onto the Restoration site.
During the monitoring period (2002 - 2007), a total of 165 species were recorded at the Restoration site, 189 species at the North reference site and 207 species at the South reference site. The Restoration site recovery is clearly aided by the addition of restoration modules (2002), increasing the amount of available habitat suitable for reef fish communities, think vertical habitat here, and recessed areas underneath these modules for fish to shelter. At the Wellwood grounding site, the overall fish diversity as well as density and biomass of most key fish families continue to be less than that of the two nearby, non-impacted reefs that were selected as monitoring reference sites. Parrotfish and surgeonfish appear to be responding the quickest to the restoration efforts, grazing along a recovering hard coral landscape currently dominated by soft corals (Gorgonians). Nearly absent today on the damaged area are sightings of grunts and snappers, both of which are seen in high frequency and abundance on surrounding reef sites with plenty of relief for them to take cover. Residency of fish, movement patterns and habitat usage are all important indicators of reef recovery. So are linking coral, invertebrate, and fish studies to see a more complete picture of how the Restoration site is improving. There are signs outside of the slowly improving trends the data show such as a little Redspotted hawkfish that has taken residence on one of the modules with lots of Ken's Staghorn coral affixed.
Many more studies are necessary to properly evaluate recovery dynamics for reefs and since most reef recoveries worldwide are hampered by other anthropogenic impacts such as overfishing, excessive nutrient loading from human pollutants, and global warming stresses, these case studies are critically important in developing mitigation strategies for damaged reefs. For the full report on our Wellwood findings, please visit our website http://www.reef.org/programs/monitoring/wellwood. REEF would like to thank the many individual REEF members who dived on this project over the past 5 years, as well as Quiesscence Dive Shop in Key Largo for dive support, and Ken Nedimyer for photos and his ongoing coral replenishment work. And finally, our thanks to the Florida Keys National Marine Sanctuary for contracting REEF for this project. We hope that this work will continue in order to monitor the long term changes in fish assemblages on the Restoration site.
