Following the most recent Indo-Pacific Lionfish expedition at Stuart Cove’s in Nassau, Bahamas, we kicked off the next phase of our critical research on this invasive species in Eleuthera. Supporters, Trish and David Ferguson, served as hosts for the week. Earlier this summer, REEF staff set up 11 study sites, tagging 30 fish on six different patch reef and clearing the other 5 sites of lionfish. This past week, I revisited those tagging sites and documented any movement of lionfish. We then following up with early morning, mid-day and evening activity observations to see what the fish were up to and when. The observations involved pre-sun up dives and 2-3 hour bottom times. With some very early and late dive times, the data collected is showing interesting patterns of low light activity.
After five days of intense data collecting at the Ferguson’s we headed down to Cape Eleuthera to meet with staff and students at the Island School and Cape Eleuthera Institute(CEI). The facility is completely self contained, producing their own electricity via solar and wind, their own biodiesel, raising cobia and tilapia in an aquaculture facility and even growing their own hydroponic vegetables. A very impressive operation and an incredible group of staff and students. We were able to conduct collecting and dissecting demonstrations for the coral research class and then do a packed house talk to all of the staff and students from TIS as well as a number from the local Deep Creek Middle School. There is strong interest in collaborating on future lionfish studies as well as incorporating fish surveys into the regular research curriculum at the IS and CEI. Look for future REEF projects to be scheduled here in 2009. Visit our Lionfish Research page for more information.
One of the best parts about fishwatching is that no matter how many surveys you have under your belt, there's always a chance to see something unexpected. Recently I was diving on Davey Crocker Reef near Tavernier in the Florida Keys with four REEF surveyors. As often happens, we got separated, me with my photography and the others surveying. I spotted a brown fish about 8 inches long “drifting” in the water just under a ledge overhang. It sort of looked like a croaker to me, but not one that I recognized. I photographed it from a distance and continued to photograph while moving closer. The fish remained still, just looking at me. Finally, when I got about 6 feet away it retreated into the gloom under the ledge.
Back on the boat we were talking fish -- as usual. One of the others commented about a strange brown fish she had seen under a ledge. It turns out everyone had seen it and no one knew what it was. The entire group were members of REEF's Advanced Assessment Team (AAT, Expert Surveyors), so no one knowing is surprising. After downloading my photos, I researched the mystery fish. My hunch was correct; it was a Croaker, a rarely seen Blue Croaker, Bairdiella batabana. These were the first sightings of this species to go into the REEF database!
So how do you know if it's a Blue Croaker? The body coloration can be copperish to bluish brown. The only distinctive marking is a white crease on the gill cover.
REEF is proud to release the latest version in our series of instructional marine life identification courses – Fishwatching in California. The California curriculum consists of three courses on one CD – divided into Southern California, Channel Islands, and Central/Northern California. Pictures and text are included and are geared for anyone interested in teaching Fish ID – ideal for dive shops and instructors, dive clubs, marine science centers and aquariums, and other groups. This course completes the library of West Coast curricula: California Fish ID, California Invertebrates and Algae, Pacific Northwest Fish, and Pacific Northwest Invertebrates. We would like to thank all of the photographers who generously donated underwater images for these courses!
These instructor-led courses are a great way to introduce divers and snorkelers to the variety of marine life that can be seen during their time in the water. Each module contains a CD-ROM with images with an easy-to-use teaching curriculum to train students in identification and REEF survey methodology. A sample starter kit is also included. Courses can be taught in approximately 2-3 hours and cover 50-70 of the most common species for an area.
The California Fish ID curriculum, along with all of the other curricula modules, are available online in REEF's store here -- http://www.reef.org/node/437

This month we feature Eco-Dives in Key West, Florida, which has been a Field Station since 2010. Eco-Dives owner, Rob McCall, is fascinated by learning and finding new species and enjoys sharing his knowledge and enthusiasm with others. Rob has been a REEF surveyor since 2001 so it was a natural to incorporate REEF into his business. Eco-Dives primarily teaches advanced open-water scuba certifications because it enables them to focus on fun courses such as underwater photography and the REEF Fish ID specialty. Eco-dives was also one of the first dive operators to offer a Lionfish Diver specialty that teaches divers the basics of the lionfish invasion, why it is so detrimental to our reefs, and how to report sightings.
“Out of 775 REEF survey dives and countless other dives with students, the most unusual fish we have found on our dives has been a pugjaw wormfish.” says Rob. Fortunately Rob was able to snap a couple pictures of it to confirm the identification of such a unique fish. Rob's sighting was only the sixth time that species had ever been reported on a REEF survey.
Although Key West is not known for its pristine reefs, Rob says the dive sites are convenient, the reefs are well-populated with small-to-medium size fish, and they have mature wrecks with plenty of big fish. The newest addition to the armada of artificial reefs in the Keys, the Vandenberg, is a great dive and a fish magnet. REEF has been monitoring the Vandenberg since it was sunk and Rob has been a great help on a number of the Advanced Assessment Team (AAT) surveys documenting reef fish recruitment over time.
Rob says that he "really enjoys working with REEF surveyors; they are always so enthusiastic. Doing surveys has made me look much harder at fish, looking for distinguishing features so I can identify them. This results in you seeing so much more during a dive."

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. To find out more about the REEF Invasive Lionfish Program, including the derby series, visit www.REEF.org/lionfish. You can also follow all of our lionfish news through our Lionfish Facebook page.
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.”
