Thirty miles offshore, in 100 feet of water, the Spike isn’t the most accessible dive site off North Florida’s coast but July 17th marked the first anniversary of the former Coast Guard tender’s deployment as an artificial reef so we were eager to see what had changed over the past year. The Spike had only been down 10 days when we surveyed it during last year’s Great Annual Fish Count. We weren’t expecting much then – the chance to dive a freshly minted reef was the main attraction, but it was interesting that it had already attracted a small crowd of nervous bottom fish, including the usual Black Sea Bass and Vermillion Snappers.
It was a very different site one year later. A large school of nosy barracudas followed the first diver down the line, clearing the way for hundreds of Atlantic Spadefish to move in and escort the rest of our group down. The Spike was surrounded by silversides that fled en masse as we moved through them, then streaked back to the structure for protection when gangs of Great Amberjack attacked. It’s difficult to describe the sound made by thousands of fleeing fish, but they are noisy. The superstructure is now covered with invertebrates – barnacles, tunicates, sponges, and anemones – that provide shelter and food for hundreds of tiny seaweed blennies. Jacksonville’s ubiquitous grunt, the Tomtate, was there in every phase from juvenile to adult. The Black Sea Bass and Vermillion snappers are now settled in under the bow with a group of small Red Snappers and waddling around in the sand was one of my favorites, a Polka-dot batfish! A year ago, I counted 6 species of fish. This year I counted 16 species.
Our group also dived the Gator Bowl Press Boxes, an artificial reef created years ago when the city’s stadium was renovated. Although it had about the same amount of biomass as the Spike, there were more species. One of the joys of offshore Jacksonville for fishwatchers is getting to see species like Dwarf Goatfish, Longspine Porgys, Bank Sea Bass and Oyster Toadfish that we see don’t tend to see in more tropical waters. Congratulations to Richard Salkin and T.C. Howe, who conducted their first REEF surveys.
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 Georgia Arrow (REEF member since 2002). Georgia lives in Portland, Oregon, has conducted 686 REEF surveys in four different regions, and is a Level 5 Expert surveyor in the Pacific. She has the most surveys of anyone in the west coast Pacific region. Here's what Georgia had to say about REEF:
When and how did you first volunteer with REEF?
I was unfortunate (or fortunate) enough to get an ear infection during my Open Water certification weekend. I was not allowed to participate in this new and exciting experience for 2 months! I checked at the dive shop and found that there was to be a Fish ID class and immediately signed up thinking it would be a lot more fun to dive if I actually knew what I was looking at-I found this to be true when birdwatching so it made sense that fishwatching would be the same. At that class, I learned about REEF and surveying and I met Janna Nichols, one of my first scuba/fish ID mentors. I wasn’t able to do the dives with the rest of the class because of my ears but when I was healthy, Janna took me on my first surveying dives. It was very exciting to be putting names to all the fish I saw on those dives. The dives were quite memorable for many reasons but knowing the fish and being able to do a survey was certainly one of them. So I have been surveying since my first dive after certification in 2002.
Have you ever been on a REEF Field Survey, and if so where and what was your trip highlight?
I went on the Sea of Cortez Field Survey in 2003. It was a wonderful trip from beginning to end. It was my first experience in warm water! I was in heaven. The divers were fun, the water was amazing, learning warm water fish was overwhelming and exciting. The highlight was diving in the middle of a school of Big Eye Scads - they were just swirling all around us and I was mesmerized.
Do you dive close to where you live, and if so, what is the best part about diving there?
Although I’ve taken several warm water trips, most of my diving is in Puget Sound, a 3 hour drive from my home. I try to get up there 3-4 times and do 8-10 surveys a month. I love the green water, I love the critters we have here from the cute little Pacific Spiny Lumpsucker to the Giant Pacific Octopus. Usually by the time I’m home from a warm water trip I am ready to get back to surveying “my” critters. It’s harder and colder to dive here but that makes it challenging. It’s hard to find some of the critters but that makes it more rewarding when you actually find that elusive fish or nudibranch.
What are some of your most favorite or memorable finds on a survey?
There are so many to choose from it is hard to pick but I have to say the Spotted Ratfish is my favorite fish. I have a Spotted Ratfish tattoo on my shoulder. It is odd-looking but so graceful underwater - it “flies” rather than swims. And it can be as cute as a little puppy dog. One of my best rare sightings is the silver-spotted sculpin.
We are pleased to announce the 2012 REEF Field Survey trip schedule - check it out online at www.REEF.org/trips. We have an exciting lineup of destinations planned and we hope you will join us. These trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. REEF staff, board members, and other REEF instructors lead these trips, and each features daily classroom seminars and a full diving schedule. 2012 destinations include: Nevis, San Blas Islands in Panama, Dominica, Belize, San Salvador in the Bahamas, Sea of Cortez, Hornby Island in British Columbia, Bermuda, the British Virgin Islands, and Cozumel.
Some call them webinars. We call them Fishinars! These free online training sessions provide fishie fun in the comfort of your own home. Fishinars are open to divers, snorkelers, and devout landlubbers alike. Anyone wanting to know more about underwater life is welcome to join in. Participation is free but you need to register for each session you want to attend. No special software is required, just a web browser. You don't need a microphone or a webcam to be able to participate. Great for first-timers or those wanting a review. These short (one hour) webinars will teach you the finer points of identifying fish and invertebrates underwater. Upcoming webinars are given below. Visit the Webinar Training page (www.REEF.org/resources/webinars) to register for one or more sessions. Also check back often as more sessions are being added. We have also posted archives of past webinars on the Webinar webpage, so if you can't join in live, you can watch it anytime.

REEF Director of Special Projects, Lad Akins, has co-authored several recent scientific publications on the invasive lionfish in the western Atlantic, including:
-Diet richness of invasive Indo-Pacific lionfish revealed by DNA barcoding. Marine Ecology Progress Series. Significant research by REEF researchers and others has been conducted looking at stomach contents of lionfish to identify prey. However, relatively few prey species have been identified because of the challenge of identifying partly digested prey. The authors of this study addressed this issue by DNA-barcoding unidentifiable fish items from the stomachs of 130 lionfish. They identified 37 prey species, half of which had previously not been recorded as lionfish prey.
-Rapid invasion of Indo-Pacific lionfishes (Pterois volitans and Pterois miles) in the Florida Keys, USA: evidence from multiple pre- and post-invasion data sets. Bulletin of Marine Science. This paper uses data from the 20,000+ REEF surveys conducted in Florida since the early 1990s, along with other long-term data sources, to document the appearance and rapid spread of lionfishes in the Florida Keys. Between 2009 and 2011, lionfish frequency of occurrence, abundance, and biomass increased rapidly, increasing three- to six-fold between 2010 and 2011 alone.
- Habitat complexity and fish size affect the detection of Indo-Pacific lionfish on invaded coral reefs. Coral Reefs. This paper explores detectability rates of lionfish using underwater visual census methods such as belt transects and stationary visual census. Knowing the error in these methods specficially for lionfish is necessary to help study this invasive species in the western Atlantic. The authors found that the two census methods detect fewer than 30% of lionfish present in an area and, in more than 50% of the cases, fail to detect any lionfish when one or more indivudals are actually present.

If you’ve read recent REEF releases, you’ve heard the news that Indo-pacific lionfish are now well established along the eastern US coast and throughout the Bahamas. REEF has been and continues to work with researchers to learn as much as we can in order to most effectively address the invasion. Since January of this year, REEF has organized and led 5 week-long projects in the Bahamas to document the extent of the invasion and gather samples and information needed by NOAA and Bahamian researchers.
Here is what we’ve found:
Here is what we are working on with NOAA and Bahamian researchers:
As part of this effort, REEF has planned more research efforts through the end of 2007. Each project will include participation of scientists, researchers, and/or REEF staff. For a list of upcoming projects visit http://www.reef.org/exotic/lionfish/ or e-mail email@example.com
Here's what we're up to in the coming months:
October 31- November 3: DEMA Show in Orlando, FL. Come visit us at both 1133 and you could win a signed print by Tom Isgar by partaking in our DEMA raffle to help raise funds for REEF.

Once again, CEDAM International is offering two scholarships for educators to participate on a REEF Field Survey. For the 2008 survey season, the scholarships will apply to the Gran Bahia Principe Field Survey in Akumal, Mexico. Dates for this trip are May 17-24, 2008. You can visit REEF's Field Survey page to view trip details and also check out the trip flyer. To apply for this scholarship, please visit the CEDAM website at then click on the Lloyd Bridges Scholarship tab at the top of the page to see details.
The two scholarships enable qualified educators to participate - at no cost - in a CEDAM-sponsored or -sanctioned expedition. This REEF Field Survey will be led by Joe Cavanaugh, REEF Field Operations Director. Participants will have the opportunity to collect data, participate in daily talks, and interact with REEF members, staff, and local organizations. This will be a hands-on experience during which participants have the opportunity for fish identification and marine conservation training in and out of the water. REEF has partnered with ReefAid and Reefcheck and Ecologica Bahia in 2007 to assist Gran Bahia Principe Resort with developing a monitoring and assessment protection plan for their nearshore reefs. Our cooperative efforts in conservation at Bahia Principe are making a difference in protecting their reefs and some of our class time will focus on these successes.
To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization.The scholarship will be awarded on the basis of both merit and financial need. CEDAM International will cover the recipient’s airfare and REEF Field Survey expenses (excluding incidentals and personal expenses), on this educational adventure. Bahia Principe is an all-inclusive resort so acoomodation, diving, and meals are included. The application deadline will be earlier than last year's deadline since the Field Survey pariticipation dates are in late May this year. Please have your completed applications submitted by April 1, 2008.
Many of our members may be too young to have seen the television program, Sea Hunt, starring Lloyd Bridges that ran from 1958-1961. One important aspect of the series was that Bridges made a plea at the end of each episode to protect the oceans, an early ocean conservation pioneer. He was also involved in several organizations including the American Oceans Campaign and Heal the Bay, a Los Angeles-based conservation group. He inspired a generation of SCUBA divers and you may want to check out Wikipedia to read more about many of the people Bridges worked with on Sea Hunt. Incidentally, I discovered that Bridges learned to SCUBA dive once contracted for the show and that he was offered the role of Captain Kirk before William Shatner!
There are still spaces (4) available for the Akumal Field Survey, email firstname.lastname@example.org to inquire.
All applicants must complete an application form and return it along with the required essay and two letters of recommendation, to CEDAM (by mail or electronically) by April 1, 2008. Good Luck!
As many of you are aware, the recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the USGS, the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem.
Our most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement. To wit:
To date, dive operators and the contributions of participating volunteers have funded the bulk of this work. REEF’s future field-work will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program.
