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.”

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 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!!!!
Hello and happy October! This edition will be REEF-in-Super-Brief since our biggest announcement - the launch of the new REEF.org website - will direct you to endless updates on REEF programs, new online tools, an improved REEF Store, and a new member-login that will allow you to get the most out of the new site. Visit www.REEF.org now!
If you're still with me, read on to learn about an exciting new artificial reef project REEF will embark on in 2008 with the sinking of the USAFS Vandenberg in Key West, Florida and REEF's participation in important inter-agency collaborative research on Marine Protected Areas (MPAs) in California. The third of six monitoring events at Biscayne National Park was recently completed; hats off to REEF staff Joe Cavanaugh and Lad Akins and Advanced Assessment Team (AAT) volunteers who served on this project amid challenging weather and personal circumstances.
Earlier this month, REEF lost a valuable partner and close personal friend. Mike "Smitty" Smith was a boat captain at Quiescence Diving Services in Key Largo, Florida and drove the boat for many local monitoring projects. His positive outlook and team spirit will be missed but we hope to honor his commitment to ocean conservation through REEF's continued work in the Florida Keys community.
"Best fishes" from the REEF family to yours,
Leda A. Cunningham, Executive Director
Welcome winter! REEF is pleased to bring you the final monthly installment of REEF-in-Brief in 2007. Our biggest announcement is the completion of the biological monitoring of the U.S.S Spiegel Grove, the largest intentional artificial reef when it was sunk in Key Largo, Florida in 2002. Also in this issue, learn about the new online data entry interface for the West Coast survey region and how to get more out of the new REEF website. Finally, we'll close out the year with some pictures from the recent Holiday Open House at REEF HQ and invite you to join us on a REEF Field Survey trip in 2008.
Many thanks to all who have made donations toward an ambitious fall fundraising goal of $100,000. REEF could not continue its critical conservation projects without your support (if we haven't heard from you yet, please click here to make a secure, tax-deductible donation online). Many thanks as well for everyone's e-patience as REEF grows its online fundraising capacity. We recognize that your
inbox and email time are limited resources and sincerely appreciate the opportunity to request your assistance in strengthening REEF citizen science programs.
The REEF family sends you best wishes and best fishes for a happy, healthy start to the new year. We'll look forward to working with you in 2008, officially designated the International Year of the Reef. It's bound to be a good year . . .
The 17th Great Annual Fish Count (GAFC) is just around the corner. While REEF staff updates the event website, www.fishcount.org, we are asking our field stations and partners to begin planning their 2008 GAFC activities.
Events can be as simple as gathering a group of local divers for a one-day dive and a covered-dish party for after. Or, schedule a huge blow out to introduce more people from your town to what a difference can be made when you do more than just blow bubbles while diving. The latter could include Fish ID seminars, counting challenges, a planned picnic and whatever else you can dream up to gather a crowd and show them the fun of fish-watching.
As any veteran fish surveyor is well aware, dive travel is the spice of fishwatching. No matter how many dives you’ve made, or how many species you’ve recorded a visit to a new destination will send you scurrying for your ID books. That was certainly the case during back-to-back REEF Field Surveys held in St. Vincent during early August. During the two weeks, 40 sets of eyes ferreted out 261 different fish species, many rare, many first-time sightings, and a few that still have the trip leaders Paul Humann and Ned DeLoach scratching their heads.
Tucked away in the distant reaches of the southeastern Caribbean, the towering volcanic island is not only home to a hearty population of Caribbean fishes, but also harbors a scattering of novel species that ride the currents north from Brazil. Add to this, pumice sand and freshwater runoff (a combination that tends to attract exotic creatures), a variety of underwater habitats ranging from bold boulder and coral seascapes, to thick sea grass meadows, and protected bays bottomed with fine sediment and scattered algae patches, fondly known as muck. Oh yeah, add one more dynamic to the amazing mix, the group’s host Bill Tewes, owner of Dive St. Vincent, and his eagle-eyed dive guides. In dive parlance, Bill is a critter hunter extraordinaire. After exploring the island’s undersea riches for 25 years, his infectious enthusiasm for the hunt won’t allow him to miss a dive, and the man certainly loves to show off his animals.
So what were some of the highlights of the week? For starters: a single dive to a clearwater site, known as the Pinnacle, revealed not one, not two, but six cryptic Black Brotula. A plunge to 110 feet on the Wall, uncovered Yellowcheek Basslet, Three-lined Basslet and Cave Bass hiding under a ledge. On their way up the surveyors spotted a Golden Hamlet, Bridled Burrfish, and during their safety stop a flashy red fin of a perky little Red Banner Blenny caught their eyes.
But as good as the reefs and wall are the majority of the team’s treasures were discovered in the muck – the seldom-dived otherworldly realm where Bill’s fishwatching prowess shines. Let’s begin in the shallows where the team found, along with a long list of more common species, clingfishes, Longsnout and Lined Seahorses, a Striated Frogfish, Shortnose Batfish, an assortment of pipefish, seldom-seen pipehorses, and about every species of snake eel you’ve ever heard of, and some you haven’t. As the seemingly barren bottom angled down Jackknifefish, Spotfin Goby, Dwarf Sand Perch and tiny Blackear Bass appeared. If you continued to 90 feet an uncommon sighting of a juvenile Snowy Bass could be made.
One would be remiss without mentioning a few spectacular St. Vincent invertebrates including, the Atlantic Longarm Octopus, the rare Brownstripe Octopus, skeleton shrimp, and a spectacular Red Banded Lobster.
Did we mention Blackfin Cardinalfish, Whitemouth Croaker, Snakefish, Cornetfish, Cardinal Soilderfish, Flying Gurnard, and pikeblennies? Whew, have to stop somewhere, this is REEF-in-Brief you know. You’ll just have to contact one of the lucky participants for more details.

REEF friend and world famous painter, diver and character extraordinaire, Ron Steven (aka Rogest), has done it again. After talking with REEF scientists about the REEF Grouper Moon Project and the important conservation research being done to study one of the last remaining spawning aggregations of the endangered Nassau grouper, Rogest created his latest piece of artwork to celebrate this Caribbean icon. "Grumpy" features the face of a Nassau grouper, with the tag line "Extinction Makes Me Grumpy". Rogest completed the painting in early summer 2009.
The artwork is being featured on T-shirts now available for sale in the REEF Gear Store. These high quality, pre-shrunk T-shirts are available in green short sleeve ($25) and red long sleeve ($30). Get yours today, they won't last long.
REEF members will have an exclusive opportunity to purchase the original painting later this Fall and Rogest will be donating over half of the proceeds to the Grouper Moon Project. We extend a big thank you to Rogest for his dedication and passion for REEF's marine conservation efforts.
