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.
We had a number of applicants for the Fall session and narrowing the intern pool to just two applicants was tough because everyone that applied were wonderful candidates. This month we're introducing you to Catherine Whitaker (aka Erin) who (thankfully) arrived early to cross train with our fabulous summer interns before they departedon August 17th. Next month we'll highlight our final recipient, Lauren Finan, who will arrive the week of August 20th.
Erin is a graduate of Duke University with a major in Environmental Science and a minor in Biology. She's had a variety of jobs during her undergraduate career all of which honed her skills in preparation for a career in Marine Biology. She is well versed in the REEF methodology having completed juvenile fish, fish, and coral abundance and distribution surveys while working with Centro Ecologico de Akumal. As a Scuba Divemaster, Erin taught scuba to tourists and locals of all ages instilling a sense of excitement and pride for marine life to her students. During her time at Duke, she served as research assistant to many professors and non-profit organizations and volunteered as an assistant aquarist at the Bermuda Aquarium.
While in Maine she was sampling algae and young lobsters for a census survey (we could use that here). At the Linney genetics laboratory Erin was responsible for feeding and cleaning tanks of 3000 zebra fish. At the Caribbean Coral Reef Ecosystems branch of the Smithsonian, Erin assisted a PhD candidate on her research relating to the effect of parrotfish on corals as well as the coral-symbiont relationship in a stressful environment, the list goes on as does her travels. She has been to Ankarafantsika, Madagascar as a field assistant; Caye Caulker, Belize as an underwater tour guide; Manila, Philippines as a U.S. Embassy Protocol Office Assistant; Sofia, Bulgaria as a U.S. Embassy Consular Section Aide. REEF is very fortunate to have someone of Erin's caliber interning with us this fall. She feels working with REEF is an ideal opportunity for her to test her ability to integrate scientific investigation, conservation efforts and a flair for reaching out to people for the betterment of our environment, while working toward her masters.
As we announced in the last edition of REEF-in-Brief, the REEF website recently underwent construction. To get the most out of the new REEF.org, REEF members need to become registered users. Registration is easy: with your REEF member number handy, click here to register. If you have misplaced your REEF member number, click here to look it up. If you are not yet a REEF member, joining is free and easy: please click here to join.
Here are a few of the new features on REEF.org.
We hope that the new REEF.org makes it easier and more enjoyable for you to participate in Diving That Counts! Feel free to contact us if you have comments, suggestions, or if you encounter a problem with any of the new features.
On April 12, REEF attended a Middle Keys Earth Day celebration at Bahia Honda State Park. It was a lovely day, albeit unseasonably hot! Several organizations had booths in attendance as well, including the Florida Keys National Marine Sanctuary (FKNMS), Dolphin Research Center, Reef Relief, the Turtle Hospital, and many others. In addition to the usual face painting and music associated with Earth Day, REEF had many visitors to our booth inquiring about who we are and how they could get involved. REEF recently stepped up our efforts to increase awareness of our organization within the Florida Keys community.
As many of you know, Key Largo is where REEF got started in the early 90's and many of our Advanced Assessment Team projects focus on local marine resources, such as FKNMS, Biscayne National Park, and the Dry Tortugas National Park. Most recently, REEF teamed with local stakeholders to create a rapid response team for the possible arrival of invasive lionfish species which many predict could be anytime, given the robust resident population of lionfish in the Bahamas and increasingly elsewhere in the Caribbean.
For those of you who are new to REEF, you can see where REEF surveys by visiting our website http://www.reef.org/about/faq. Essentially, REEF members survey areas covering the tropical western Atlantic from Brasil to Florida and along the eastern seaboard through the northeastern U.S. and Canada, the Pacific coast of Canada and California southward through the tropical eastern Pacific down to the Galapagos Islands, Hawaii, and in the not-too-distant future, American Samoa.
REEF has a new volunteer helping us in the office and who helped staff the REEF booth, Laura Aichinger Dias. Laura came to us a couple of months ago inquiring about opportunities at REEF. Since then, she has been conducting survey dives and honing her fish identification skills. She is already accomplished in her own right, receiving her Master of Science from Florida Atlantic University. Her thesis focused on dolphin population dynamics in Sepetiba Bay in Brasil, where she is from originally. Laura will help REEF with projects this spring and hopes to become part of our Advanced Assessment Team by the end of the summer so she can participate in future projects. For more information on becoming an Advanced Assessment Team member, please review the requirements at http://www.reef.org/programs/volunteersurvey/aat AAT members are utilized in most of our monitoring and assessment contracts with government and non-government agencies. Essentially, REEF members take fish ID classes and pass qualification quizzes in tandem with gaining a prerequisite number of survey dives, all leading to membership in the AAT. The ultimate reward is that once you are placed on the AAT list-serve you will be emailed opportunities to participate in projects oftentimes where the diving is paid for by the sponsoring agency. You also will gain increased fish ID acumen by diving with other AAT members and learning to find and identify the really small and cryptic species. For more information beyond the website, please email Joe Cavanaugh at email@example.com or our Director of Science, Christy Semmens at firstname.lastname@example.org.
