Mangroves provide important nursery habitat for coral reef fishes, such as grunts, snappers, and others. While this has been shown locally in some studies, a new paper by scientists from NOAA Fisheries and University of Miami RSMAS used REEF Volunteer Fish Survey Project data to evaluate mangrove-reef connectivity at the Caribbean regional scale. Their findings, recently published in the scientific journal PLoS ONE, showed that the size of nearby mangrove forests directly influences reef fish densities of at least 6 species.This study is a great example of the power and impact that long-term, wide-spread citizen science programs such as the REEF Volunteer Fish Survey Project can have on addressing important ecological and management questions that would otherwise be near impossible to evaluate. Way to go REEF surveyors! Visit www.REEF.org/db/publications to see this and all of the 50+ scientific publications that have included REEF Volunteer Fish Survey Project data.
Every year, more than 10,000 dive professionals from around the world attend DEMA, the flagship event of its namesake, the Diving Equipment and Marketing Association. This year, DEMA will be held October 31-November 3 in Orlando, Florida. REEF is proud to host a booth and present three environmental seminars on how dive operators can promote "fish watching" and the REEF Volunteer Fish Survey Project to recruit and retain their dive customers. Our audience includes dive shop owners, industry reps, instructors, underwater photographers, destination and travel companies, dive magazines and many other members of the international dive community who will convene to share best practices and learn about new products coming on the market.
Recognizing the important role of the dive community in marine conservation, an increasing number of environmental organizations will attend DEMA as well. Partners including The Ocean Conservancy, Oceana, and Project AWARE Foundation will also reach out to divers to enlist their support for important conservation issues. REEF will take this four-day opportunity to raise awareness about the Volunteer Fish Survey Project, recruit new Field Stations, connect with key partners and raise the profile of REEF programs as a way for the dive industry to give back to the underwater environment. We will also be launching a home-study DVD course for beginning fish watchers; stay tuned to REEF in Brief for more information.
REEF is looking for a few good volunteers to help at our DEMA booth this year. Since DEMA is only open to dive professionals, this is a great way to get in to see the show. If you can help out for a few hours each of the show, please contact REEF office manager Kim Sovia-Crandon to join the REEF DEMA 2007 team: Kim@reef.org or (305) 852-0030.

Are you a REEF surveyor along the US and Canadian West coast or Hawaii? If so, did you know that you can now enter your data ONLINE! No more scanforms (unless you really want to use them - they'll still work – although note that there will be a fee to purchase scanforms beginning in 2008). No more scrounging around to find a pencil. No more stamps and trips to the post office. All you need to do is click on Submit Data Online under the Database menu and you're on your way. Entering data online is not only easy for you, it greatly eases the workload on the limited REEF staff, enhances the quality of the data and reduces typographical errors, and most importantly, it greatly decreases the processing time from 8 weeks or more for paper scanforms to typically within 2 weeks from the time of online submission.
REEF plans to add the Northeast (Virginia through Newfoundland) and the Tropical Eastern Pacific (Baja Mexico to the Galapagos Islands) regions to the online submission program over the next few months in order for all of our program regions to be covered by this convenient data management feature.
REEF is happy to announce our new partnership with Caradonna Dive Adventures as our travel provider, beginning with our 2009 Field Survey Season. As many of you already know, Caradonna brings years of dive travel acumen and great vendor partnerships, both of which will undoubtedly assist REEF in making our Field Survey Program once again our signature Citizen Science program.
After all, it is each of you that make all that REEF does in and out of the water possible. We are closing in on 120,000 Fish Surveys in our world-renowned fish sightings database. Christy Semmens (REEF Director of Science) and I individually review all of the 1,000 plus surveys entered into the database every month. We know all of you by name but it is only on our Field Programs that REEF Staff and Board members have the opportunity to put the names to the faces and share the fish surveying exhilaration with you.
Many of you who use dive travel services have probably used Caradonna in the past and know how good they are at setting up exhilarating dive trips. With Caradonna, you'll almost have a third dive buddy right there with you, wherever you might be! We are previewing our 2009 Season (below) and will be posting additional details and more trips to the website in the coming weeks. Doris Pfister at Caradonna will serve as our REEF liaison. Doris and I have worked hard these past couple of months to coordinate this exciting schedule.
So without further ado, a preview -
2009 Field Survey Schedule Preview
Additional destinations that we are working on include St. Vincent, Maui (Hawaii), Bermuda with Ned DeLoach, and Cancun. Stay tuned to the REEF Trips webpage.
For all bookings, please contact Doris Pfister, our REEF Dedicated Sales Consultant at REEF@caradonna.com or by phone at 1-877-295-REEF(7333). Details and more trips will be added in the next few weeks and months, so please check the REEF Trips webpage often.
Have you ever wondered how trip locations are decided? There is a suite of considerations for Field Survey locations, including REEF data needs, diving and tourist infrastructure, costs (evermore important with rising travel costs), partnership and outreach opportunities, fish abundance and diversity, invasive species, educational value, resource management needs, and yes, fun too! In 2009, REEF staff are planning improvements to our Field Survey program including increased capacity building while the REEF group is onsite and after the trip is over, and increasing the opportunities for resource managers to partner with REEF and utilize the valuable data you collect. By fostering regional capacity building efforts wherein local stakeholders begin to carry the surveying efforts beyond single events, there is increased likelihood these data will be used for ongoing management decisions.
REEF eclipsed a milestone this week when the REEF Volunteer Survey Project Database passed the 120,000 survey mark. This represents over 150,000 hours of underwater survey time from our volunteers. The achievement comes almost 15 years to the day when the first REEF fish survey was conducted off Key Largo, Florida, on July 17, 1993. Today, the program is going strong throughout the coastal areas of North and Central America, the Caribbean, Bahamas, Galapagos Islands and Hawaii. In the tropical western Atlantic region alone, 96,469 surveys have been conducted at 6,085 sites and 795 fish species have been recorded. Of course, improving your marine life identification skills, building your lifelist of sighted species, and conducting surveys are a lot of fun. But have you ever wondered what good are all of these data?
Volunteer data collection, or citizen science, provides a valuable alternative for scientists and resource agencies needing information but lacking sufficient resources to gather it. In addition, involvement in data collection leads to greater awareness about marine resources and creates a stewardship ethic among key user groups.
In addition to providing data summaries on the REEF Website, REEF staff provide raw data to scientists and resource agencies. REEF data have been used in the development of stock assessments (Kingsley 2004), in the evaluation of trends of fish species (Semmens et al. 2000), to measure the effect of marine protected areas on kelp forest fish communities (Semmens et al. in prep) and coral reefs (REEF 2003), as an indicator of population pressure on natural resources (Burke and Maidens 2004), to evaluate interactions between species and species-habitat relationships (Auster et al. 2005), to asses the effect of restoration efforts in areas of damaged reef (REEF 2008), and to asses the status of a group of reef fish species that is experiencing significant declines (Ward-Paige et al., in prep A and B). REEF volunteers have been instrumental in the identification and removal of exotic species (Semmens et al. 2004), in the identification of new species (Taylor and Akins 2007; Weaver and Rocha 2007) and morphological variants of known species (Pattengill-Semmens 1999), and in the documentation of previously unrecorded range extensions (M. Taylor and J. Van Tassel, Pers. Comm.). PDFs of most of these articles and a full listing of scientific papers and reports that have used REEF data are included in the Publications section of the REEF Website.
REEF extends a big thank you to the 10,000+ volunteers who have contributed to this database over the years and we are looking forward to the next 120,000 surveys! Be sure to visit the Top 10 Stats page to see a quick rundown of REEF survey activity. You can also explore the data more in-depth by visiting the Database section of the REEF.org Website.
The upcoming Peter Hughes Belize Lionfish awareness/outreach trip turns to lionfish research/removal after the first lionfish was discovered in Central American waters. Join REEF aboard the Sun Dancer II from June 13-20 for this exciting and fun diving adventures. Following eye opening presentations by REEF staff and partners at the recent DEMA dive show in October, long-time supporter Peter Hughes took on a new mission - to support REEF's efforts in addressing the lionfish invasion in the Caribbean. With his world-renowned fleet of liveaboard dive vessels and concern for the marine environment, Peter became an instant supporter after hearing details of the invasion. In stepping up to the plate, he offered his Belize-based liveaboard, Sun Dancer II, as a platform to raise funds and increase awareness of the issue during a June 13-20 expedition. Little did he know that within 2 short months, lionfish would actually show up in Belize in advance of our planned project.
Sun Dancer II instructors, leading a group of divers on Turneffe Reef, spotted a juvenile lionfish on December 11, 2008. Subsequent dives provided images verifying the sighting and Sun Dancer Captain Ryan Barnett, who had previously worked with REEF during Bahamas lionfish projects, put the early warning system into action through his report to REEF HQ. While the fish has yet to be recovered, Sun Dancer staff now have divers on the lookout and are stocking the vessel with collecting supplies.
While the fundraising efforts of the June project remain, the focus of the June project has now shifted to include more detailed data gathering and collection of any lionfish specimens found. Additional workshops are being organized with Belizean authorities to assist in development and implementation of their lionfish response plan. For those interested in joining the June 13-20 project aboard the Sun Dancer, please view the project webpage or contact Peter Hughes Diving directly at (800) 9-DANCER. For more information on the lionfish issue and to support REEF's efforts, go to www.reef.org/lionfish or contact Lad Akins (Lad@REEF.org) (305) 852-0030.

The first time we ever saw Hamlets spawn, Ned and I were on a liveaboard REEF trip in Belize. We were just starting serious work on the behavior book at the time and still unaware of just how rewarding dusk dives can be for fish watchers. Trying to squeeze in a fourth dive before dark, our group dropped in just before sunset, agreeing to be back up in time for dinner.
These were the days when I could still add new fish to my life list on almost every dive trip and the charismatic Hamlets with their 11 distinct color morphs and various “hybrid” variations were especially prized sightings (we’ll save the species debate for another day). Hamlets are solitary hunters during the day. So when we saw two chasing each other about, we instinctively knew something out of the ordinary was happening. But, was it love or war?
The traditional color of one of the pair was noticeably blanched. We’d seen that happen with fighting Sailfin blennies - the fish that was out of its hole turns very pale. But the behavior of the Hamlets was more reminiscent of flirtation rather than conflict. The fish being pursued would race ahead then stop, usually with its nose pointed up, twitch, and immediately take off once again as soon as the pursuer caught up. For over twenty minutes they dashed about in all directions before always returning to the same coral head.
Finally, just as the last light was fading, the hamlets paused above the coral head only inches apart, entwined their 3-inch bodies and slowly rose together a foot or two. I know we aren’t supposed to anthropomorphize, but it certainly looked like love to us. Suddenly, they popped apart releasing a white puff of gametes and immediately darted back toward the reef. Instead of going their separate ways, the chasing, nuzzling and twitching began anew and shortly they spawned again, then again and again before they finally disappeared, going their separate ways into the night.
Later we learned to our amazement that Hamlets are simultaneous hermaphrodites, with each partner possessing both male and female reproductive organs. This unusual scenario, known as egg trading, allows each couple to play both the male and female role each evening. The fish assuming the role of the female plays the aggressor, twitching and chasing the blanched, interim male about. After each spawn the roles reverse until the lovers are finally spent.
The best news for fishwatchers is Hamlets appear to spawn each evening year-round. So, on your next dusk dive in the Tropical Western Atlantic make a point of watching for Hamlets; if you do you’re sure to be entertained.
Note: a short video of Spawning Hamlets is available on REEF’s YouTube Channel, WeSpeakFish: http://www.youtube.com/watch?v=lEMCqVBB0CM
REEF recently completed a Field Survey trip to Roatan, Honduras, led by REEF co-founder, Paul Humann. Over six days, the group completed 17 survey dives including one night dive. Both novice and highly experienced REEF surveyors enjoyed the near perfect weather and dive conditions. Shortfin pipehorses, wrasse blennies, linesnout gobies, peppermint basslets, orangesided gobies, dash gobies, and blue dartfish are a sample of the cryptic fishes that were observed. Spotted Eagle Rays and Southern Stingrays graced us with their presence on a number of dives.
The group stayed on the east end of the island at Turquoise Bay Resort and dove with Subway Scuba. The highpoint of the trip was the Aguila Wreck and surrounding reef where there were numerous species of large grouper and snapper. There was a dog snapper displaying body bars similar to those sometimes on Cubera Snappers and Schoolmasters. Also, there was a Yellowmouth Grouper with an unusual pattern of dense brown dots covering the body. Paul remarked that he had never seen either species with these unusual markings.
A not so welcome sighting was the invasive red lionfish; one or more were sighted on nearly every dive. Alecia Adamson, REEF’s new Field Operations and Outreach Coordinator, collected 15 lionfish over the course of the week ranging in size from 2 to 14 inches. The local divemasters were also collecting lionfish but were not aware that lionfish filets are delectable. Alecia gave them a demonstration on how to safely filet lionfish. Now the dive staff captures lionfish for both control and culinary purposes!
Congratulations to those who attained a higher surveyor experience level during the week - Bobbi Kerridge and Peter Rae are now Level 3 surveyors and Pat Lommel is a new Level 5 Expert surveyor!
Field Surveys are a great way to take a dive vacation that counts! If you would like to join in one of our future Field Surveys, there are a few spots available for the upcoming trips to Cozumel, Key Largo, Bonaire, and Grand Cayman. Please visit the Field Survey Trip Schedule online to find more information.
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:
- A researcher from Florida State University requested data from sites along the west coast of Florida to evaluate how fish species richness is influenced by the presence of certain grouper species.
- A scientist from the Smithsonian Institute is mapping the distribution and co-occurance of garden eel species in the western Atlantic.
- A researcher from NOAA Fisheries is looking at the species distribution of Gray Snapper.
