In response to requests from the scientific community, we are adding a new species to monitor on REEF surveys in the Tropical Western Atlantic (TWA) - Diadema antillarum, the Long-Spined Sea Urchin. In the early 1980s, a large die-off of Diadema occurred throughout the TWA. This has had a significant and long-lasting impact on coral reefs in the region because Diadema is (was) one of the primary grazers on Caribbean coral reefs (keeping rocks clear for baby corals to establish and keeping algae from overgrowing established corals). The disappearance of Diadema, coupled with overfishing of grazing fish species such as parrotfish and surgeonfish in some parts of the Caribbean along with other complicating factors, has resulted in many algae-dominated reefs. Despite 20+ years since the die-off, the once wide-spread and abundant species has failed to recover in most places in the Caribbean. There is a growing collective of researchers who are hoping to map the current distribution and abundance of Diadema. REEF will be assisting this effort by including Diadema in our TWA protocol. Surveyors will report whether they were actively looking for Diadema or not, and if they were, in what abundance category (S,F,M,A - same as for fish). We are currently working on the necessary training materials and additions to the database, and the new protocol will be in place soon.
Last year we shared an article about a new non-native fish, the Regal Demoiselle (Neopomacentrus cyanamos), showing up in the southwestern Gulf of Mexico. REEF surveyors in the Yucatan region of Mexico have since reported the species. And now a new publication co-authored by REEF staff Lad Akins documents that the species could become established and spread in the western Atlantic. The study incorporated a computer model to evaluate the the non-native species’ potential to impact native populations. On the basis of this work, it is foreseeable that the reefs presently harboring Regal Damselfish will likely see increased abundance of this damsel. Immediate attempts to eliminate the fish, therefore, should be focused in nearshore shallow waters spanning Veracruz to Frontera, Mexico. To find out more about this study, published last month in the journal Marine Biology, and to see a complete list of the 50+ scientific publications that have featured REEF data, visit www.REEF.org/db/publications.
The species is native to the Indo-Pacific and Red Sea. Similar in appearance to the native Brown Chromis, the Regal Damsel is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the fins and tail. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin.
If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.
We have one week left in our summer matching campaign, and want to thank everyone who has given so far. This summer, we are highlighting all the amazing discoveries made possible by generous donations from members like you!
To make a contribution, please visit www.REEF.org/donate.
According to the National Oceanic and Atmospheric Administration (NOAA), “To date, we have explored less than five percent of our oceans.” What does that mean for REEF and our members? It means that there is so much out there to discover! Every year, REEF members are finding new species, and REEF scientists are investigating the lifecycles and behaviors of critical marine species. We are constantly learning new things about ocean wildlife that contribute to their survival.
It also means that all these new discoveries can help regulatory agencies and policymakers to make more informed decisions on how to manage our fisheries. In cases like the threatened Nassau Grouper, seasonal protections during spawning seasons have been developed. In the case of invasive species, like lionfish, removal events are being encouraged because they have been proven effective at controlling lionfish populations.
Please take this opportunity to make a contribution this summer and help REEF continue to make these important discoveries that ultimately protect marine species around the world! Thank you again to all our members who support us in our mission, and have a great summer!
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 Jet Long. Jet lives in California, and has been a REEF member since 2013. He has participated in several REEF Field Survey Trips and has conducted over 50 surveys. Here’s what Jet had to say about REEF:
When and how did you first volunteer with REEF?
I first heard about REEF from fellow REEF member Hideko Kawabata during a volunteering trip. Doing fish surveys all over the world sounded like an interesting idea to me. I spent more time learning about REEF when I got home and decided to join. My first REEF trip was in 2013 to Southern Bahamas on Turks and Caicos Explorer II. I learned a lot about lionfishes (e.g. anatomy, how to hunt and cook them). Since then, I try to do at least one REEF fish survey trip every year.
If you have been on a REEF Field Survey, where and what was your trip highlight?
I have done a few REEF Field Surveys. The one I like the most so far is the Philippines Dumaguete Atlantis Resort trip. It might be because it was the first time I did muck diving. The fishes and creatures that you could find were amazing (e.g. many types of anemone fishes, bobtail squids, slingjaw wrasse, mantis shrimps). The highlight was no doubt swimming with the world’s largest fish – whale sharks!
What is your favorite part about being a REEF member?
There are a lot of good reasons why you want to be a REEF member. You can help to establish a fish database which is used by different research projects. You will visit places that you may not think of visiting. But the best part is the expansion of your knowledge on fishes, sea creatures, and the ocean when you are on a field survey trip. You will see the underwater world differently once you learn more about it. You will learn the importance of protecting our ocean.
What is your favorite place to dive?
I would have to say the Coral Triangle. Its high concentration of fishes, corals, and other species is really amazing.
What is the most fascinating fish encounter you’ve experienced?
When I was in Dumaguete Philippines, I saw two Black-saddled Tobies facing off with each other. At first, they were in the middle of the water column. They then spiraled down towards the bottom. They eventually glided through each other’s body. I didn’t expect this to happen.
What is your favorite fish or invertebrate?
Ocean’s giant gentle Manta Ray is my favorite fish. It was absolutely beautiful to watch them swimming and hovering the cleaning station.
Do you have any surveying, fish watching or identification tips for the REEF members?
Do more! The more you do, the better you will be in identifying the fishes in a particular region. Before each field trip, one should spend some time watching the Fishinars to get familiar with the fishes. In addition, a fish ID book is a really useful tool to learn about the fishes before and during the trip.
What is your most memorable fish find and why?
Seeing a Crocodile Flathead hiding in the sea grass during the Palau trip was really neat. Its camouflage body made it almost impossible to locate. I was just lucky to look at that specific patch of sea grass. The fish that I really want to sea underwater is Ocean Sunfish (aka Mola Mola), which is supposed to be the world’s heaviest bony fish.
To those who are in the know, St Vincent is considered the critter capital of the Caribbean. To those who watch fish, it is known that the rare is commonplace and that the fishwatching is unlike any other location in the Caribbean. REEF’s data from the June Field Survey supports those claims. With a team of 13 divers, the REEF group recorded an astounding 243 species, more than 65 of which were unlisted “write-ins” on the survey forms.
Diving with Bills Tewes at Dive St Vincent, long time REEF supporter and widely regarded “Caribbean Character”, the team split up on two boats and survey sites around the southwest end of the island. Long-time REEF expert Franklin Neal provided an extra special view from above and into shallow water as he snorkeled, while other team members spent hours on each dive exploring varied habitats and depths.
Special finds during the week would take an entire newsletter to list, but there were a few fish that stood out including the still undescribed Bluebar Jawfish on most sites, five frog fish on one dive, multiple black brotula, various pipefish commonly sighted and the largest spotfin gobies (10 inches?!) we’ve ever seen. The fish of the week may well have been the Golden Hamlet that Bill pointed out as his favorite fish and the species that adorns the cover of Reef Fish Identification.
The diving was bottom time unlimited and many dives exceeded two hours finishing in shallow water. Habitats were varied and visibility ranged from good to excellent on all of our dives. REEF is already planning our next Field Survey to dive St Vincent in August of 2008. The project will be led by Paul Humann and will be a must for any serious fishwatcher. For more details, contact Joe@reef.org
REEF recently completed our AAT monitoring of Biscayne National Park (BNP). Over the last two years, we have monitored fish assemblages inside the marine park at 6 separate locations twice each year (March and September) to correlate our results with historical data that BNP has collected. REEF’s future collaboration with BNP is yet to be determined but will likely involve assisting them with the potential establishment of a protected area somewhere within the Park’s boundaries. REEF is excited to have this opportunity to continue working with BNP this upcoming spring so please stay tuned for more information once our future project is defined.
Meanwhile, I would like to personally thank the monitoring team from our last event for their “above and beyond the call” efforts to get the job done. We had weather issues that delayed the project by a full week, followed by a tragic death in the Key Largo diving community in losing Mike Smith. All of us at REEF especially acknowledge Lad Akins for his efforts as our boat captain, Rob Bleser (owner of Quiescence Dive Shop where Mike worked) for pushing this project through under very difficult circumstances, and Steve Campbell for acting as boat captain on our last day. And thank you to the diving team for juggling your schedules to make sure we had enough divers each day: Jesse Armacost, Dave Grenda, Brian Hufford, Lillian Kenney, Mike Phelan, and Joyce Schulke. Everyone pulled together through the above challenges and I was proud to dive with each of you.
The REEF 2008 Field Survey Schedule is in full swing. Many of the trips are already sold out, but we wanted to bring your attention to one that still has some space on it -- the Field Survey to Baja Mexico aboard the Don Jose in the Sea of Cortez this October. This is a great trip, with spectacular diving and lots of tropical fishes, warm and clear water, and beautiful topside scenery. Some of the highlights include giant hawkfish, jawfish the size of your leg, whale sharks and manta rays, and spectacular sunsets over unpopulated desert islands. This will be the 5th time that REEF has done this amazing trip, and there is a good reason we keep going back. Come see what it's all about. The trip begins and ends in La Paz Mexico aboard the Don Jose live-aboard. Dr. Brice Semmens, reef fish ecologist and expert in Baja fishes, will be leading this trip.
This Field Survey is only held every few years so don't miss your chance! To find out more, check out the trip flyer. To secure your space, contact Jeanne at Baja Expeditions, 800-843-6967, firstname.lastname@example.org.
October 5 - 12, 2008 -- $1,550 - $1,750 per person, depending on room type. Package Includes: Six nights shipboard accommodations and one night local hotel accommodations in La Paz. Meals are included, beginning with breakfast on Day 2 and end with lunch on Day 7, and includes beer, soda and wine while shipboard.
In January, 2008 the National Aquarium Institute organized and conducted a Bahamian conservation expedition on the Aqua Cat live-aboard dive vessel. Our mission was to conduct REEF surveys and work on the invasive lionfish project. On board this trip were Lad Akins (REEF Special Projects Director), Ned and Anna DeLoach, Chris Flook (Bermuda Aquarium), National Aquarium staff, and aquarium and REEF volunteers. In addition to meeting the lionfish research goals of the cruise, we were treated to not one but two exciting and rare finds - the Exuma goby and the lemon goby.
At a dive site in Eleuthera called Cave Rock Reef we geared up and readied ourselves for lionfish behavior monitoring. Just as I started getting my gear together Anna came to the surface to tell me she had found a school of Exuma gobies, Gobiosoma atronasum. What I had not realized was that the keen eye of Bruce Purdy, owner of the Aqua Cat and avid REEF surveyor and supporter had noticed them at this site before and he had directed Anna to the exact coral head. I have logged over 400 dives in the Bahamas and until this day the Exuma goby had always eluded me. To the casual observer this fish looks like a cleaning goby or sharknose goby until you notice its behavior. Unlike most other “neon-type” gobies, the Exuma Goby spends most of its time hovering in the water column, not perched on the coral. They act very similar to the masked and glass gobies. Excited to add a new species to my life list I leave the small cluster of these great fish and head down to my assigned duty of monitoring a lionfish.
Two days later, while on a dive at Blacktip Wall in the Exumas, I noticed a few fish mixed in with school bass. These fish looked out of place and very different from anything I had ever seen. I noted as much detail as possible on my REEF slate and swam on hoping that one of my fellow trip members would be able to help me identify it. As it turns out no one had any idea what it was, but luckily Ned had also seen this odd fish and had taken some great photos of it. After some research when we returned from the trip, we discovered this fish was a lemon goby, Vomerogobius flavus. The lemon goby is an exciting new fish to the REEF database. This species was identified and described in 1971 from 11 Bahamian specimens, but this sighting in the Exumas is a range extension for the species.
It was truly a rewarding experience to finally see and survey the Exuma goby that I have searched for on many trips. To document a fish that I did not even know existed was the icing on the cake. For a fish lover like me, getting to find a new species for the REEF database is an honor. REEF surveying truly keeps diving exciting and new. I am concerned about the effects that the invasive lionfish could have on these two species of gobies with such a narrow range in which they live, but the data from all of our great volunteers helps us track these changes. It would be a shame to lose such unique endemic species due to this foreign invader. We hope you enjoy seeing some of the first photos ever published of these two goby gems.
Processing and error checking the 1,000+ REEF surveys submitted each month by our members as part of the Volunteer Survey Project is one of REEF's highest priorities. With limited staff and resources, there are a few things that you can do to help us maintain the integrity of this incredible database. Most importantly - whenever possible, please submit your data through the Online Data Entry interface, http://www.REEF.org/dataentry. Turnaround time is typically 1-3 weeks, compared with 8-12 weeks for paper scansheets. Plus it saves postage and paper! The second most important way you can help -- if you are submitting data on scansheets, please have your REEF member number and complete 8-digit zone code filled in on the form before mailing it to REEF. Read on for more helpful hints.
Online Data Entry Tips
REEF is currently modifying our Online Data Entry program for surveys from the Tropical Eastern Pacific and the Northeast. We hope to have this available soon.
On April 25, 2009 we celebrated history in Key Largo. It was a beautiful tropical day with the REEF parking lot covered in tents, tables and chairs, fish balloons with cold drinks and appetizers island music being offered up. People came from near and far as we all helped celebrate the dedication of the James E Lockwood REEF Headquarters. The afternoon celebrated the merging of three paths - that of a dive industry pioneer, a historic building in the Florida Keys and a grass-roots environmental organization. The gift by James E. Lockwood will go a long way in helping REEF protect, educate and enable divers, snorkelers and armchair enthusiasts to make the world a better place.
Casey Wilder, REEF Program Assistant, designed a beautiful program that outlined how we all ended up in the parking lot on this day. Make sure you check out the online version of this little piece of history. The program provides an overview of the history of James E. Lockwood, a true diving pioneer, the 1913 Conch House that houses REEF and the history of REEF and how all three ended up moving forward together as of 4/25/09.
Special guests Mike Dorn and John Campbell provided the history of Mr. Lockwood, which is incredibly fascinating and diverse. Paul Humann and Ned De Loach spoke on behalf of REEF and talked about how REEF is Key Largo’s very own home grown environmental 501(c)(3), making it very relevant that REEF’s office are housed in the oldest building in Key Largo. Following the ribbon cutting ceremony, we unveiled the beautiful new plaque commemorating the James E. Lockwood REEF Headquarters and the date the house was built. The Conch house even received a spiffy new coat of paint so she was dressed for the occasion. Special thanks to Bill Corbett of Keys Home Improvement for doing such a superb job in record time!
The next time you are in the Keys be sure to stop by the James E Lockwood REEF Headquarters, MM 98.3 in the median and enjoy a little history, mingle with REEF staff and shop for the fish.
