REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations. Our fintastically outstanding field station this month is the Maui FIN (Fish Identification Network) group in Hawaii. This enthusiastic group of divers and snorkelers has been going strong for years. They meet on the 2nd Saturday of each month to conduct surveys at different spots around Maui. After introducing REEF to the Hawaiian Islands 10 years ago, Donna Brown and Liz Foote (who taught our online Hawaiian Fishinar last week), started building a team of enthusiastic fish surveyors. It was out of that enthusiasm that surveyor Mike Fausnaugh started the FIN group. Flo Bahr and Rick Long have been longtime active leaders of the group. When snorkeling, they all put orange duct tape at the tops of their snorkels. This helps the group find each other while in the water, as well as make them easy to spot from the beach. Tourists also ask about what they're doing and this helps show how many are out there doing REEF surveys. In addition to the monthly FIN survey dives, they maintain a Facebook page for the group that serves as a great communication tool. Through the Facebook page, they organize their next survey spots, share zone codes, spread announcements, and post photos and mystery fish questions. Keep up the enthusiastic surveying, FINsters!
This summer REEF, in partnership with Divers Direct and SeaGrant Florida, hosted its third annual Lionfish Derby Series. The series included four derbies in Florida (Miami, Fort Lauderdale, West Palm Beach, and Key Largo) and one in Green Turtle Key, Bahamas. The event series was a huge success—in total, 219 participants in 60 teams brought in a total of 2,694 lionfish! Lionfish are invasive predators capable of consuming prey in excess of half their body size and have become a hazard to Caribbean reefs by consuming commercially, recreationally and ecologically important fish and crustaceans. Using published estimates of lionfish consumption, the removal of the 1,923 lionfish collected in the Florida derbies corresponds to preventing between approximately 3.5 million to 14.8 million prey fish from being eaten by these lionfish over the next year.
Lionfish derbies serve as a way to engage the public and media, enhance awareness, encourage removals and provide samples for researchers. During each the derby over $3,500 in cash prizes sponsored by Divers Direct were awarded to first, second, and third place winners in three categories: Most, Largest, and Smallest.
Since their introduction in the 1980’s, invasive lionfish have become the first marine predator to successfully establish in the Tropical Western Atlantic. Unfortunately, complete eradication of lionfish is unlikely, but where removal efforts are sustained, population numbers and impacts can be reduced. REEF and Simon Fraser University partnered throughout the 2012 Derby Series to conduct research on the effectiveness of derbies in controlling local populations. Preliminary data analysis from the 2012 Green Turtle Key, Bahamas, Derby shows that lionfish derbies are effective at removing 65% of lionfish off of local reefs. The Derby Series is one of the many ways REEF is promoting lionfish control. A big thank you goes out to the derby sponsors, hosts, teams and everyone who came out to support the events.

More than sixty people gathered earlier this month at the Fish House Encore in Key Largo, Florida, for Lionfish Food and Wine Night. Before dining, event attendees learned about the lionfish invasion and the importance of removing lionfish from marine environments. Peter Tselikis, chef at Fish House Encore, showed the audience how to cook two popular lionfish dishes. Lad Akins, a renowned lionfish expert and REEF Director of Special Projects, taught the audience how to fillet lionfish, avoiding the venomous spines.
The invasive species, known for their voracious appetites and rapid reproduction, was prepared four different ways with a creative medley of ingredients and wine selections. Entrées included bacon-wrapped barbeque lionfish, sea salt-cured lionfish ceviche, and poached lionfish. Many guests said their favorite dish was Lionfish Bermuda, a lionfish fillet encrusted with fried red onions and Japanese breadcrumbs, baked and served with a sweet and sour sauce atop baby arugula salad.
“It’s exciting to see such strong public and commercial interest in consuming lionfish,” says Akins. “Developing a market for lionfish is a great way to provide incentive for increased removals. Even non-divers can make a real impact, by ordering the fish at their local restaurants, helping to decrease lionfish populations and minimize their impacts.”
Lionfish, native to the Indo-Pacific and Red Sea, have now invaded the Western Atlantic, Caribbean, and Gulf of Mexico. In the invaded range, they have been documented to be gluttonous predators of native fish and invertebrates. One published study co-authored by Akins (Green et al. 2012) shows lionfish reduced the native fish prey community at some sites in the Bahamas by an average of 65% in just two years. Some sites had a 95% decline. Despite the dismal outlook, there is good news. Published studies show local control by divers and fishers can be effective, Akins notes. “Removing lionfish from local reefs is like weeding a garden. Remove weeds and the garden is healthier. Remove lionfish and the reefs are healthier. The key is regular removals, year round.”

This month we highlight Juddith Cucco. Judith has been a REEF member since 2010, and has conducted 555 surveys (all in her home state of Hawaii, and all as a snorkeler!). She is a member of the Hawaii Advanced Assessment Team as an Expert Surveyor. Here's what Judith had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I first heard about REEF through Reef Watch Waikiki while taking a fish identification course with them in February 2010. I immediately started doing surveys as I felt it was a fun way for me to share my enthusiasm for all the fish I see while snorkeling in Hawaii, where I live...and I wanted a record of the many species I've encountered.
What is the most fascinating fish encounter you’ve experienced? What is your favorite fish find?
Even though I've seen it many times, it still fascinates me to see cooperative hunting, for example jacks following a moray eel or blue goatfish. My favorite fish is the juvenile rockmover wrasse. They look like drifting seaweed in the ocean when they move and I enjoy watching them turn over rocks with their snout. My favorite discovery is a semi-circle angelfish (not native to Hawaii) that Christy Pattengill-Semmens (REEF Director of Science ) helped my swimming buddies and me identify from some very poor photos.
Where do you do most of your surveying?
I used to do most of my surveys at the outer reef in Hanauma Bay and still go there occasionally, however my favorite place to survey on Oahu is Kaiona Beach Park. You really need to look to find the fish and if one has the patience, there are ample rewards. I've seen so many species that one does not see at Hanauma Bay (knifefish, bigeyes and several types of scorpionfish). Because I snorkel, the fish are also much closer at Kaiona as it's more shallow.
What do you enjoy most about doing REEF surveys?
The most exciting thing for me when doing surveys is when I encounter a species I haven't seen before. After my snorkel, I go home and look it up in one of my fish books or online and enjoy learning about it. My biggest challenge is staying warm as I like to stay in the ocean until my fingers get numb (not recommended), which is usually around three hours even with a full wet suit.
Do you have a memorable story from a survey?
Just the other day, I had gone out for a snorkel survey (which ended up not happening). A little while into our swim, my buddy and I found an entangled green sea turtle. I saw it on the bottom in about ten feet of water. We first asked its permission, then dove down to bring it to the surface. We saw that it had fishing line wrapped around its neck and two front flippers. We were really far out on the reef and swam it in to shore. We recruited two fishermen to cut off the line and they also built a pen out of rocks for the turtle. I went to my car and called our local NOAA turtle stranding office. When NOAA staff arrived, we loaded the turtle in a carrier and the turtle was taken to a surgeon. It needs to have the front right flipper amputated, but it is going to survive and should eventually be released back in the wild. What an amazing and cooperative experience!!!!

This month we highlight Roger Skillman. Roger has been a REEF member since 2009, and has conducted 45 surveys. Despite being landlocked in the Smoky Mountains, he is an active surveyor in the Carolinas and Florida. He also teaches SCUBA and incorporates REEF in to his classes! Here's what Roger had to say about REEF:
What’s your favorite part of REEF surveying?
I like completing REEF surveys to document what was seen on any given day at a particular dive site. Completing surveys helps establish baseline data for a site. REEF members are “Citizen Scientists” with their eyes in the water and we provide valuable data for researchers that can’t be everywhere. The most interesting thing I have found about completing surveys is the importance of an underwater camera and a variety of good fish ID books to help with identification after the dive.
Do you have a favorite place to do surveys?
I have two favorite places that I like to dive. Most of my 34 years of diving have been on the shipwrecks offshore of Beaufort, North Carolina. The historical shipwrecks and abundant marine life that can be found rivals diving anywhere around the world! During the last 5 years, I have discovered the great diving around Jupiter, Florida, to include the world famous Blue Heron Bridge. BHB, with its unusual creatures and the ledges offshore, provide as many different species of fish as many tropical locales.
What is your favorite fish find?
My most fascinating fish encounter has to be diving with the Sand Tiger Sharks on the shipwreck “Caribsea” offshore Cape Lookout, NC. Diving while surrounded by 50 of these magnificent creatures was a marvelous experience. A most memorable fish find occurred at Blue Heron Bridge in 2013. I was completing open water evaluations with two of my students when we found not one, but two, Striated Frogfish. I had never seen a frogfish and these “neophyte” divers saw TWO on their first ever open water dives! Sometimes life just doesn’t seem fair!
What advice do you have for other REEF members?
The best way to benefit from REEF is to get INVOLVED! I belong to inland-based REEF Field Station (Smoky Mountain Divers-Carolinas) but that doesn’t stop us from conducting surveys. Contact our field station or a field station near you and participate in their fish ID programs. Sign up and participate in the numerous webinars and classes offered by REEF to expand your knowledge. It’s not hard, just FUN!
We are encouraging all REEF surveyors in the Tropical Western Atlantic region to be on the lookout for a new non-native fish! Researchers from the University of Veracruz have documented a new non-native species in the southwestern Gulf of Mexico with the potential to spread throughout the region. Sightings of the Regal Demoiselle (Neopomacentrus cyanamos) have recently come from the nearshore reef systems south of Veracruz, Mexico. The species is native to a broad region of the Indo-Pacific and Red Sea. The damselfish was documented at depths from 2-21 meters, though it was more common on deeper reefs. Similar in appearance to the native Brown Chromis, the Regal Damsel can reach sizes of up to 9 cm (3.5 inches) in length and 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 tail, dorsal and anal fins. 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. Observations from Dr. Ross Robertson indicate the Regal Demoiselle can be a bit more cryptic than the native Chromis, tending to hide under ledges and in crevices between corals, rather than swimming in the open. Experts in Mexico believe that this damsel has the potential to disrupt natural systems around Caribbean reefs, as they have witnessed displacement of the native Brown Chromis on heavily-invaded sites.
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 are proud to share a story from the East Coast that is a perfect example of how REEF data are put to work to address our changing seas. Dr. Peter Auster of the University of Connecticut and Mystic Aquarium, recently submitted a petition to add the Radiated Shanny and Atlantic Seasnail to the list of Species of Concern under the State of Connecticut's Endangered Species Act. Dr. Auster used REEF data as his primary source of information for the petition.
Both species are considered "cold-adapted," with their distribution largely north of Cape Cod with rare sightings in Long Island Sound. Data show that these species may be the first climate-change casualties in Connecticut waters as Long Island Sound continues to warm. These species occur in rocky habitats, and the best population data come from diver surveys, such as those from the REEF Volunteer Fish Survey Project. If you are a REEF surveyor in the northeast region, please keep an eye out and report these species on your surveys! Dr. Auster will continue to track their abundance through the REEF database and assess the effect of changing seas on their populations.
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.
