REEF is excited to announce the release of Invasive Lionfish: A Guide to Control and Management. Available as an e-book to view and/or download (formatted for desktop and mobile devices), this extensive manual was created to aid coastal managers and field workers in effectively managing the invasive lionfish problem. This best practices manual consists of chapters on control strategies, outreach and education plans, research, monitoring, legal considerations, and ideas for acquiring resources and vital partnerships from around the region. Invasive lionfish are a major ecological disaster causing wide-reaching negative impacts throughout the western Atlantic, Caribbean and Gulf of Mexico. By utilizing examples provided in this guide, researchers and managers throughout the region will be well equipped to address the lionfish invasion.
This work would not have been possible without the collaborative efforts of NOAA, REEF, ICRI, the United Nations Environment Programme, Caribbean Environment Programme, SPAWRAC, and the 40+ participants of the 2010 Caribbean Regional Lionfish Workshop. This manual will be the first book in the new GCFI Special Publication Series. Authors include James Morris (NOAA), Dayne Buddo (University of the West Indies, Jamaica), Stephanie Green (Simon Frasier University), Ricardo Lozano (CONANP, Mexico), and Lad Akins (REEF).
We are excited to announce the 2013 Summer Lionfish Derby Series! Five years ago, REEF began hosting lionfish derbies throughout Florida and the Caribbean to address the lionfish invasion. A lionfish derby is a single day team competition to collect as many lionfish as possible. Teams collect lionfish using nets or spears while SCUBA diving or free diving, and prizes are awarded to the teams with the most lionfish, biggest lionfish, and smallest lionfish caught. Not only do these events reduce lionfish populations, but they also increase education and awareness, provide samples for research, train divers in safe removal techniques, and help develop the market for lionfish as a food fish. To register or learn more, please visit www.REEF.org/lionfish/derbies. 2013 Derby dates and locations are: June 22 - Green Turtle Cay Bahamas; July 27 - Fort Lauderdale, FL; August 17 - Palm Beach, FL; September 14 - Key Largo, FL.
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:
-Fisheries scientist are using data on Hogfish from Florida, Puerto Rico, and the USVI to evaluate population status and help set effective catch limits as part of the US Fisheries Management Council's stock assessment.
- A scientist from RSMAS at the University of Miami is evaluating the status of Caribbean predatory fish species, including Gray Snapper, Barracuda, and Goliath Grouper.
- An environmental researcher at University of Miami is assessing biodiversity indexes as a measure of effectiveness with ongoing septic tank replacement and canal improvement projects in the Florida Keys.
- A PhD student from University of Hawaii is using data from Maui Nui to conduct coral reef ecosystem services models.
- A researcher from University of Victoria is using data from Washington and British Columbia to evaluate community richness values for temperate rocky reefs.
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 Herb Gruenhagen. Herb has been a REEF member since 2001, and has conducted 208 surveys (all in his home state of California). He is a member of the Pacific Coast Advanced Assessment Team as an Expert Surveyor. Here's what Herb had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
In July 2000, the San Diego Ocean Foundation sunk a Canadian Destroyer as an artificial reef. I was one of several divers who performed both fish and invertebrate surveys, using transects, quadrats, and REEF Roving Surveys. When the San Diego Oceans Foundation decided to become a REEF Field Station, I volunteered to become a volunteer REEF instructor. I have been teaching a REEF class each month in San Diego since that time.
What are some of the highlights of your local diving?
I dive the La Jolla Shores most of the time, and it is always changing. There are the resident species, the transients, and the seasonal ones. The resident species will always be there no matter what. The transients can be the many pelagic species that the currents bring in. For example, a while back, we are seeing several different species of jellyfish and the leopard sharks are returning to the warmer water shallows near the Marine Room. The seasonal species are really the special surprises. During the early spring the nudibranchs come out to start their mating, and in the winter, we have a ‘white’ Christmas with all the Market squid schooling, mating, and laying their white finger-like egg cases. Other special surprises can be molas, baby grey whales, midshipman, mantis shrimp, wolf-fishes, and even Finescale Triggerfishes.
What is the most interesting thing you’ve learned doing a REEF fish survey?
Doing REEF surveys really highlights the many different variations that a given species can take on. Being a REEF surveyor gives you the ability to recognize new species from common species, and all the many variations within the same species. Paying attention to all the details is really important to getting a good ID. I try to get a good image of the fish and ask for help when I’m not sure.
In your opinion, what is the most important aspect of REEF’s projects and programs?
After all the years of teaching the courses, I’m just really glad to see local divers coming to my class to expand their knowledge of the local marine life, whether they do one survey or many surveys. I love watching the learning process and expanding the students minds of the many wonderful forms of marine life we have here to enjoy and need to perserve for future generations.
Do you have a favorite local (or not) REEF field station or dive shop?
The REEF Field station is the San Diego Oceans Foundation, but the facilities that we use is Ocean Enterprises in San Diego. Ocean Enterprises has been very supportive over the years and everyone really appreciates the use of their classrooms, computer and projector and its central location in the city. Thank you Ocean Enterprises for your many years of support.
What is the most fascinating fish encounter you’ve experienced? What is your favorite?
Well, of course photographing species new to science or that is rare or very uncommon is a highlight. I have photographed several fishes and nudibranchs that fall into one of those categories. My most fascinating fish that I have seen is the Specklefin Midshipman, Porichthys myriaste. We see many juvenile Plainfin Midshipman in the winter, but the Specklefin were quite a find! One of my favorite fishes is the Sarcastic Fringehead. They are one of the few fishes that see you as a threat and will interact with divers and their photo gear. They will charge out of their breeding holes (ok, we are talking about a 6” fish) at the camera lens, thinking they are seeing ‘another’ fringehead in the lens. They will bite all your cables and your finger and charge back into their hole. They will also interact with each other and fearlessly defend their breeding holes by opening their mouths at each other beyond the stretching point.
Herb teaches free Southern California Marine Life ID classes the third Wednesday of each month. Join him!
Are you an experienced REEF surveyor in the Tropical Western Atlantic (TWA)? If so, you might want to check out our brand new underwater survey paper featuring an extended list of species. The double-sided list fits on the regular yellow slate. The longer list of species means less write-in species and more efficient data entry. When entering your data, just select the longer list in the "Species View" field at the top of the data entry field. You can find the new paper in REEF's online store here - http://www.reef.org/node/433. The store also includes new paper for our Central Indo-Pacific and South Pacific/Fiji regions, along with handy ID guides, and REEF gear!
As we continue to showcase our valuable interns, I mentioned in last months newsletter that we would introduce our remaining fall intern. With that thought in mind please join REEF in welcoming Lauren Finan. Lauren is a student at the University of Colorado Boulder, pursuing her studies in Environmental Policy which is why she was such a good candidate for our program. She has a strong passion for the quality of our reefs and the ocean and diligently championed for our last remaining fall intern slot. An avid diver since age 14, she became interested in the quality of our delicate ecosystem, however, due to her locale in Boulder, she was totally landlocked and did not have the ability to get out and dive, and she will be doing plenty of that now, along with working her way through the various levels of our Fish Identification Course. Lauren role here at REEF will be the coordination of our presence at DEMA this year, as well as maintaining our membership data updates and working on the improvement of our educational/outreach program. We're fortunate that both our fall interns will be with us until December.
Bonnie Greenberg recently joined REEF as the office manager. She brings with her more than 20 years of experience in non-profit management and entrepreneurship: including work with Marathon Community Theatre, Habitat for Humanity of the Upper Keys , director of marketing with a family business in Pennsylvania and a few years working as a journalist for local media. She likes to snorkel, sail, spend time with friends, read great books now and then, and create a good meal. Having said for years she was writing her own version of the Great American Novel - Bonnie spent the past two years as the front desk associate with a small Florida Keys Resort while she toiled at her story. She’s about half-way there. She holds a BFA from Emerson College. Bonnie resides in Key Largo, FL with her long-term boyfriend and 3 cats. Next time you find yourself in Key Largo, please swing by REEF HQ to meet Bonnie and the other REEF staff.
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.

With the rapid expansion of lionfish into the Caribbean, downstream and recently invaded countries are starting to gear up for early detection and rapid response efforts. REEF is leading the way with in-country workshops focused on increasing awareness and training both fisheries and dive operators in collecting and handling techniques. The week of January 25th-31st was spent working with the Department of Environment and Coastal Resources (DECR) in the Turks and Caicos Islands.
Starting in Grand Turk, we hit the ground running and less than an hour after landing, DECR officer Jodi Johnson and I had covered collecting and handling techniques and had our first 2 lionfish in the bag. Things did not slow down. Two days in Grand Turk followed by two days in Provo and a day in South Caicos resulted in 7 seminars to well over 150 people, 6 collecting training dives, over 40 lionfish collected and an evening lionfish tasting at Smokey’s on the Beach in Provo. Media coverage of the effort was also prominent with local TCI Channel 4 running a feature segment on the issue. The workshop was a huge success with both dive operators and government officials now moving forward in combined efforts to control and minimize impacts of lionfish.
In separate upcoming events, Bonaire, Cayman Islands, Cozumel and Belize are also bringing REEF in to conduct lionfish workshops this spring and early summer. The goals of these programs are to build capacity for local communities and governments to be able to enact early detection and rapid response measures and increase public awareness of the issue.
