The San Diego Oceans Foundation (SDOF) is one of REEF's valued partner organizations. SDOF has been supporting its volunteers to participate in REEF surveying for the last several years and has sponsored dozens of survey training workshops. SDOF recently honored REEF member, Bob Hillis, who is a long-time SDOF Reef Monitoring Volunteer, as their 2009 top volunteer for his invaluable support of the oceans. Having completed 202 REEF Surveys, Bob has continued to strengthen his connection to the sea while providing indispensable information about the status of marine populations off the coast of California. Bob joined REEF in 2006 and is a member of the REEF Pacific Advanced Assessment Team (AAT). In addition to being an active surveyor, he and his wife helped spread the REEF word last year at our SCUBA Show 2009 booth.
Bob says - “I started doing surveys when I saw a notice for an SDOF Fish ID class on the Divebums website. I had started fish watching a few years before when I reached the "been there, done that" point of diving in San Diego. I started diving here in the early '70's and did all the abalone, lobster, blue water spearfishing, divemaster, instructor, dive medtech and public safety diver things. I live in the mountains (about 60 miles from the coast), but the ocean is my favorite playground! I am also an avid surfer, body surfer and ocean swimmer. Doing REEF surveys with SDOF gives me an opportunity to enjoy my passions and give a little back to the ocean as well. These surveys actually force me to focus on and identify all of the species that I used to see (but not REALLY see). Always hoping to locate a new or rare species has added a new and exciting dimension to diving.”
Thanks for your efforts, Bob, and congratulations! And thanks to SDOF for their continued support of the REEF program.
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.

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:
- A researcher from University of British Columbia is using REEF data to evaluate the efficacy of marine reserves in Canadian waters.
- A researcher from Florida State University has requested REEF data to study Goliath Grouper populations in Florida.
- A student at Coastal Carolina University is using data to study fish populations at Discovery Bay in Jamaica.
- Scientists from NOAA Fisheries and Scripps Institution of Oceanography are using data from multiple monitoring programs, including REEF, to evaluate new methods of evaluating population trends in fisheries.

REEF Grouper Moon scientists co-authored a recent groundbreaking paper in the journal PLoS One that highlights the importance of regional conservation efforts aimed at spawning aggregations in the Caribbean. This study evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean using DNA markers. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean. These results suggest that, despite a lack of physical barriers, Nassau Grouper form multiple distinct sub-populations in the Caribbean Sea. Oceanography (regional currents, eddies) likely plays an important role in retaining larvae close to spawning sites at both local and regional spatial scales. These findings highlight the importance of conservation initiatives such at REEF's Grouper Moon program in the Cayman Islands. A PDF of the paper is available online here. You can see a complete list of all scientific papers that have included data from REEF programs at www.REEF.org/db/publications.
