Blue Croaker -- What a Find

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 partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.

    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."

    Outstanding in their Field: Featured REEF Field Station, Maui FIN

    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!

    2012 REEF Lionfish Derby Series Remove 2,694 Invasive Fish

    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.

    A new scientific paper published earlier this month in the journal Methods in Ecology and Evolution reports that REEF surveys conducted by citizen scientists compare well with traditional scientific methods when it comes to monitoring species biodiversity. The findings of the research, conducted by Dr. Ben Holt from University of East Angila in the UK, give weight to the growing phenomenon of citizen science programs such as REEF's Volunteer Survey Project. The field study compared methods used by REEF volunteer divers with those used by professional scientists to measure the variety of fish species in three Caribbean sites in the Turks and Caicos. The divers surveyed the sites using two methods – the 'belt transect', used in peer reviewed fish diversity studies, and the 'roving diver technique', used by REEF volunteers. Two teams of 12 divers made 144 separate underwater surveys across the sites over four weeks. While the traditional scientific survey revealed sightings of 106 different types of fish, the volunteer technique detected greater marine diversity with a total of 137 in the same waters. Dr Holt led the research in partnership with the Centre for Marine Resource Studies in the Caribbean and the University of Copenhagen, Denmark. He said: "The results of this study are important for the future of citizen science and the use of data collected by these programs. Very few, if any, scientific groups can collect data on the scale that volunteer groups can, so our proof that both methods return consistent results is very encouraging for citizen science in general. We're living in a world that's changing very significantly. Environmental changes are having a big impact on ecosystems around us so we need to harness new ways of measuring the effect. Our study demonstrates the quality of data collected using a volunteer method can match, and in some respects exceed, protocols used by professional scientists."

    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 Nick Brown. A US Pacific Northwest native, Nick is currently living in St. Kitts. Nick has been a REEF member since 2004 and has since conducted 138 surveys. He is a member of the PAC Advanced Assessment Team. Here's what Nick had to say about REEF:

    How did you first volunteer with REEF?

    I first became involved with REEF in 2004 while working as a research intern for the SeaDoc Society, a marine ecosystem health program based in Washington State. The SeaDoc Society and REEF frequently collaborate to offer free fish and invertebrate identification courses to the public. Although I was still completing my open water certification at the time, the enthusiasm of SeaDoc’s chief scientist Joe Gaydos and REEF’s Janna Nichols was contagious. Within a month of finishing my certification, I completed my first REEF survey and haven’t stopped since.

    What inspires you to complete REEF surveys?

    I take great satisfaction in knowing that every survey I submit contributes to an ever growing database that can be used by the public, researchers and policy makers around the world. Not only am I adding more purpose to my dives by contributing to something useful, I’m able to reference my submitted data later on which functions as my own personal invertebrate (in the PAC region) and fish sighting logbook.

    Do you dive close to where you live, and if so, what is the best part about diving there?

    I’ve been very fortunate in being able to dive very close to where I live. Until about a year and a half ago, the vast majority of my dives were in the cold but beautiful waters of my home state of Washington and nearby British Columbia, an area known locally as the Salish Sea. My favorite part about diving in the Pacific Northwest is the large diversity of marine invertebrates. Recently though, I’ve hung up my drysuit and slipped into a wetsuit for the warm Caribbean waters of St. Kitts and Nevis where I’m currently attending veterinary school. My favorite part of Caribbean diving is the great visibility and large variety of ornately colored fish.

    Do you have any surveying, fishwatching, or identification tips for REEF members?

    For better surveying and fish watching move slowly; not only will your dive last longer, but you’ll notice more and the marine life tends not to be as shy. For identification, I recommend investing in a few fish and invertebrate ID books; often the subtleties between different species are hard to appreciate without a detailed reference.
