There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems. REEF Director of Special Projects, Lad Akins, is a co-author on a recently published paper evaluating these effects. The study was published in the scientific journal, PLoS ONE. Lead author, Stephanie Green, from Simon Fraser University (SFU), along with Akins and other co-authors Aleks Maljković (SFU), and Isabelle Côté (SFU), documented a dramatic 65% decline in 42 species of reef fish eaten by lionfish over a two year period. The study, conducted off New Providence Island in the Bahamas, used data collected during REEF's volunteer lionfish projects to track the explosion of the lionfish population over time, and reveals that lionfish biomass increased from 23% to nearly 40% of the predator biomass on the study sites between 2008 and 2010. This study represents the first documented direct impact of lionfish predation on native reef fishes and highlights the importance of control programs to minimize impacts. You can find a link to this and all published papers that have included REEF data on our Publications page.

REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Paul and Marta Bonatz. Marta joined REEF in 1998 and she drew Paul in 2005. They have become active surveyors, and each has conducted 240 surveys. Here's what they had to say about REEF:
What is your favorite part about being a REEF member?
Our favorite part of being REEF members is working with a network of other “citizen scientists” to make a difference. Interacting with like-minded divers in an organization that is focused on saving the marine environment is fulfilling. It’s also gratifying to see the change in newly recruited “fish geeks” as they learn more about the underwater world.
If you have been on a REEF field survey, where and what was your trip highlight?
We’ve been on two REEF field survey trips and plan to do more! The first, which hooked us on fish watching, was to Culebra, Puerto Rico. The highlight was the abundant staghorn coral. Unfortunately, it was totally devoid of adult fish. Our second trip was a lionfish control study in Belize. Spending a week focused on spotting and capturing 506 lionfish in the Belize Atolls with Peter Hughes and Lad Akins was exhilarating. We learned about the hazard this invasive species poses to the indigenous Caribbean fish population, and we now work to educate others about this urgent problem.
Where is your favorite place to dive and why?
Avid divers are frequently asked to name their favorite vacation destination. When we are asked this question our honest response is “Wherever we are currently diving”. REEF surveying teaches you to appreciate interesting finds on every dive. We sometimes spend an entire dive in a few square yards watching small critters in their habitat. Although every location is unique, the place we visit most frequently is Little Cayman. The sheerness of Bloody Bay wall, the healthy marine environment, and the stunning Nassau Grouper make for an incomparable mixture.
What is the most fascinating marine encounter you’ve experienced?
We have to include two favorite underwater encounters – we couldn’t agree on just one! The first was on a Manta Ray research trip to the Maldives. At a break in the action while monitoring Mantas on 5 x 1 hour shifts at North Male Atoll, we discovered an octopus positioned on a rock quietly observing us from the distance of a few feet. He welcomed us back every shift! The second was an encounter with a dolphin named “Spot" on Cayman Brac. Spot arrived on Cayman Brac after Hurricane Mitch, and he swam and played with divers on many of the Brac dive sites. Spot disappeared one day and everyone feared the worst. Two years later while diving in Cayman Brac we noticed a pod of dolphins near the boat. Spot edged up to the boat to show off his new family. He wouldn’t let us interact with him anymore, but he wanted everyone to know he was healthy and happy in his new life. It was an electric moment.

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!

As part of the NOAA-funded Coastal Partnership Initiative, REEF has joined forces with Florida SeaGrant to organize and conduct a series of lionfish collecting and handling workshops and hands on training dives in Southeast Florida. REEF Staff trained over 75 divers during recent workshops and dives in the Florida Keys, Miami, and Palm Beach. The project also includes organized removals by local volunteer teams throughout the year. Additional workshops and dives are planned through the summer for the entire southeast Florida coast and it is anticipated that, after training, organized removal efforts will take place year round. For a list, and to register for upcoming workshops and dives, visit http://www.REEF.org/lionfish/workshops.

REEF Field Surveys trips that are a great introduction to fish identification for novice fishwatchers, and a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. REEF coordinates Field Surveys to locations throughout our project regions each year. These projects are led by REEF staff and other REEF instructors and feature daily classroom seminars and a full diving schedule. Many of the 2012 REEF Field Survey trips are sold out, but there are still a few spots on the lionfish research expedition to Dominica, the fish behavior trip to Bermuda, and a liveaboard through the British Virgin Islands. We are also working on an exciting lineup for the 2013 schedule. We will announce the full lineup and details soon. Destinations include Fiji, Curacao, Turks and Caicos, Utila, and the Soccoro Islands. Get in touch with our travel experts at Caradonna to find out more and to book your space - 1-877-295-7333 (REEF), or via e-mail REEF@caradonna.com. The full schedule and more information can be found online at http://www.REEF.org/trips.
