On July 17th, Maui celebrated its tenth year as part of the the Great Annual Fish Count (GAFC) with a great event at the Honolua Bay Marine Life Conservation District. As part of the event, several community groups combined to hold a REEF fish count, reef and shoreline clean-up, coral disease survey, and water quality testing. Long-time REEF partners, Donna Brown and Liz Foote, conducted a fish identification class at the Hawaiian Islands Humpback Whale National Marine Sanctuary the week before, and the Sanctuary furnished a van and organized a car pool to travel to the remote location. Trilogy Excursions donated a 64 foot sailing catamaran and crew to carry volunteers into the bay, and later invited the shore-based fish counters aboard for a free lunch. REEF surveyors saw and photographed over 70 fish species, including sea horses, oriental helmet gurnard, spotted eagle ray, and a cute baby frogfish. The GAFC is one of the monthly events hosted by the Maui-based Fish Identification Network (FIN). Visitors and new comers are welcome to attend monthly fish counts by contacting: Maui.FIN@gmail.com
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.

REEF's Director of Special Projects, Lad Akins, and REEF affiliate scientist Dr. Stephanie Green (Oregon State University) and REEF Advisory Panel member Dr. Steve Gittings (NOAA National Marine Sanctuaries) participated in the first submersible expedition to assess the lionfish invasion on deep marine habitats off South Florida June 27-29. While REEF and other scientists have studied lionfish in shallow habitats, the Antipodes lionfish expedition gave scientists the opportunity to learn about lionfish populations far below recreational diving limits. The five person submersible is capable of descending to 300 m (1,000 ft) deep and has large acrylic domes that allow for observations and photography.
During the expedition, team members including Dr. Gittings and Dr. Green completed dives to 300ft in the submersible to look for lionfish on both natural rocky and artificial reefs, including the 209ft-long cargo ship Bill Boyd. Both scientists sighted dozens of invasive lionfish in all habitat types during the dive, highlighted by view of the stern of the wreck holding dozens of lionfish. Dr. Green also conducted a number of REEF surveys to document the native fish community in areas invaded by lionfish, sighting a number of reef fishes that are often only found below recreational dive limits, including snowy grouper, roughtongue bass, red barbier, short bigeye, and bank butterflyfish.
The project, hosted by NOVA Southeastern University, was led by OceanGate Inc. and included participants from Florida Fish and Wildlife Conservation Commission, University of Miami, NOVA, and Guy Harvey Foundation, and others. On Saturday following the expedition dives, Lad Akins, Dr. Green, and Dr. Gittings met with media and the public in a half-day summit to discuss the invasion and potential actions to manage lionfish populations in areas that can't regularly be accessed by divers. The summit concluded with a lionfish filleting demonstration by Lad, and a tasting of lionfish ceviche prepared by Kareem Anguin, Executive Chef, The Oceanaire Seafood Room. See the expedition website for more information.
As part of a Florida Sea Grant funded project, REEF is working this summer to assess deepwater lionfish populations in the Florida Keys using ROVs and technical divers.

The 22nd annual Great Annual Fish Count (GAFC) is rapidly approaching! Will you be participating? We encourage local shops, dive clubs, and other groups to organize an activity anytime during the month of July (and often training events in June). You can view events already scheduled, and add your own, by visiting www.fishcount.org.
The concept behind the GAFC is to not only accumulate large numbers of surveys during the month of July, but to introduce divers and snorkelers to Fishwatching and conducting REEF surveys. Interested groups can offer free fish ID classes, organize dive/snorkel days, and turn them into fun gatherings! To find out more, contact us at email@example.com.
A recent publication in the scientific journal, Conservation Letters, examined the invasion of lionfish in to the western Atlantic and Gulf of Mexico waters. The authors compared traditional reef fish monitoring efforts to less traditional data including the observations of divers through REEF's Volunteer Fish Survey Project and spearfishers. They found that citizen observations documented lionfish 1-2 years earlier and more frequently than the more traditional monitoring efforts. The authors also explored the willingness of spearfishers to help minimize impacts of the invasion by harvesting lionfish. They found that spearfishers who had encountered more lionfish while diving perceived them as more harmful to the habitat than less experienced divers and were also more likely to participate in harvesting initiatives. The authors also report that encouragement from scientists and managers was a far better motivator than the desire to harvest lionfish for personal consumption. This study demonstrates the value of engaging citizens for assessing and responding to large-scale and time-sensitive conservation problems.
