In this edition, learn about REEF's participation in the 54th annual Boston Sea Rovers international underwater clinic, a visit with Congresswoman Ileana Ros-Lehtinen and a citizen science discussion series recently hosted by REEF in the Florida Keys. Two valuable REEF members learn bi-coastal fish ID and there is one spot left on the Turks and Caicos field survey next month. Last chance to sign up for this amazing conservation diving opportunity!
With best wishes and best fishes,
Dr. Jim Bohnsac is our Science Liaison to the Board of Directors and a Fisheries Biologist with NOAA. Recently, Jim has been interviewed several times about the effectiveness of the Dry Tortugas National Park in protecting fish species inside and outside of the protected areas. The Dry Tortugas lie approximately 70 miles SW of Key West and are an integral part of the greater Keys coral reef ecosystem.
No-fishing zones studied, Protective areas aim to increase size, number of fish

DRY TORTUGAS NATIONAL PARK - Reeling in a 45-pound grouper used to be just an average day on the water in the Florida Keys. The abundance of behemoth fish attracted anglers from around the world in the early 1900s, including adventurers such as Ernest Hemingway and Zane Grey, who pulled in monsters from the clear, warm depths off Key West. But as Florida's population boomed, the attraction that drew them began to vanish. Anglers were snapping up the larger fish by the thousands. An average grouper caught in the Keys now is about 8 pounds. "We were starting to look like a Third World nation in regards to having blitzed our resources," said University of Miami marine biologist Jerald Ault.
Mr. Ault and others are studying whether putting large tracts of ocean off-limits to fishing in the Keys can help species rebound - and prove a way to help reverse the effects of overfishing worldwide. Federal and state scientists, along with University of Miami researchers, wrapped up a 20-day study on June 9 after 1,710 dives in the region, surveying fish sizes and abundance, in an effort to determine whether it's working. Critics assert that it isn't. They say limiting size and catch quantities, not fencing off the seas, will help restore ocean life.
The fierce debate has raged between scientists and anglers for years. Some studies suggest the outcome could mean life or death for not only commercial and sport fishing, but for mass seafood consumption as it exists today. Florida has the largest contiguous "no-take" zone in the continental U.S. - about 140 square miles are off limits to fishing in and around Dry Tortugas National Park, a cluster of seven sandy islands about 70 miles west off Key West amid the sparkling blue-green waters that teem with tropical marine life. Nearby, another 60 square miles are also off limits.The region is home to some 300 fish species and lies within a crucial coral reef habitat at the convergence of the Gulf of Mexico, the Caribbean Sea and the Atlantic Ocean.

REEF Director of Science, Dr. Christy Pattengill-Semmens, and Grouper Moon Scientists, Dr. Brice Semmens (NOAA) and Dr. Scott Heppell (Oregon State University), participated in the Gulf and Caribbean Fisheries Institute (GCFI) meeting last month in Guadeloupe. This annual meeting brings together scientists, fishermen, resource agency managers, and marine conservation organizations to present and discuss current topics and emerging findings on coral reef resources of the tropical western Atlantic waters. Christy presented preliminary results from an analysis of data from the Florida Keys National Marine Sanctuaries no-take sites (Sanctuary Preservation Areas) as part of the Marine Protected Areas session. Christy also represented
REEF during the special session on Marine Invasive Species. She presented an overview of the role that REEF's outreach programs and large corps of volunteer divers have played to better understand the impact of the Indo-Pacific Lionfish on western Atlantic reefs and to help slow the invasion of this unwanted species. Christy also participated in a panel discussion that followed the session.
Both Brice and Scott presented recent Grouper Moon Project results during the Spawning Aggregation session. Thanks to funding from the Lenfest Ocean Program at the Pew Charitable Trusts, our grouper work in the Cayman Islands has greatly expanded and includes ground-breaking conservation research. Brice's presentation focused on the expansion of the work to Cayman Brac, an island where the historical aggregation was fished heavily and was assumed to be non-functional. Scott presented exciting findings from a pilot study conducted earlier this year to understand where Nassau grouper larvae go after they are released from the Little Cayman aggregation site.
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.
