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.
Active REEF surveyor and Advanced Assessment Team member, Patti Chandler and her husband Scott, recently found a new fish species for Bonaire! Scott and Patti, of ReefNet, were in Bonaire as presenters for the Second Annual Fish ID Challenge. Nearing the end of a lengthy night dive on Bari Reef over sand, in 10 feet of water, something very strange was illuminated by their video lights catching Scott and Patti's eyes. It was a clear fish,1 inch in length, with a rounded tail, and large pectoral fins that practically encircled it, giving it an appearance of wearing a tutu with yellow dots.
The little fish was very active in the water column making photography and videography more of a challenge than usual. This fish was a very young juvenile, more precisely described in the scientific community as post larval in the "settling stage". As they were at a loss for its identification, photos of the strange little fish were sent off for identification to Les Wilk, Head of Scientific Research at ReefNet who in turn sent them to Benjamin Victor, who is the recognized expert for juveniles of any kind, especially larvae. Ben is a frequent poster to the REEF Discussion Forums and has a very useful website, www.coralreeffish.com.
Ben made a positive ID for the wacky little fish. It is a juvenile Reef Bass, Pseudogramma gregoryi! The adult version of the Reef Bass looks totally different. Very few reference guides even mention this obscure but beautiful fish. You can see a photo of the adult at on the bottom of this webpage. The new species was reported on Patti's REEF survey and will be added to the species count for Bonaire. Bonaire's Bari Reef is the ONLY place this fish has ever been reported to REEF in the entire Tropical Western Atlantic! Bari Reef was already the number one reported reef for species diversity in Tropical Western Atlantic and this new species just increases the lead.
The Annual Fish ID Challenge is sponsored by Bonaire Dive & Adventure, Budget Car Rental, ReefNet, and Sand Dollar Condominium Resort for promotion of marine education and conservation.Share on Facebook
Last Summer, REEF friend and world famous painter, diver and character extraordinaire, Ron Steven (aka Rogest), created a brand new piece celebrating the Nassau grouper. Rogest was inspired after talking with REEF scientists about the REEF Grouper Moon Project and the important conservation research being done to study one of the last remaining spawning aggregations of the endangered Nassau grouper. Rogest painted "Grumpy", which features the face of a Nassau grouper, with the tag line "Extinction Makes Me Grumpy". He has since been inspired to create additional pieces with Grumpy. REEF members will have an exclusive opportunity to purchase one of these original paintings later this Spring and Rogest will be donating over half of the proceeds to the Grouper Moon Project. More information coming soon. We extend a big thank you to Rogest for his dedication and passion for REEF's marine conservation efforts. The artwork is also being featured on T-shirts available for sale in the REEF Gear Store.
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
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:
- Researchers from the Centro de Ecología Marina de Utila requested data on yellowtail snapper and other snapper and grouper species. The group is working to develop an ecosystem approach to managing Caribbean coral reefs in the face of climate change .
- Scientists from NOAA Fisheries are using sightings of the Indo-Pacific lionfish in REEF surveys to evaluate the rapid invasion of this species into the Florida Keys.
REEF Director of Science, Christy Pattengill-Semmens, and REEF Outreach Coordinator, Janna Nichols, attended a rockfish conference in Seattle earlier this week. The workshop, Rockfish Recovery in the Salish Sea: Research and Management Priorities, was organized by NOAA, WDFW, and the SeaDoc Society, and served as a venue for scientists, managers, and policy makers from throughout the region to share their work and help chart a course for future work. Christy presented an overview of REEF data collected throughout the Salish Sea, and showed distribution maps for 12 species of rockfish. The REEF Volunteer Survey Program expanded to the Northwest in 1998. To date, REEF volunteers have submitted 12,495 surveys from 781 sites throughout the Salish Sea. These data are a valuable information resource for those working to protect and restore declining rockfish populations. Several other active Pacific Northwest surveyors also attended the conference.

REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations. This month we feature the Dive Club of Silicon Valley. The dive club started organizing Great Annual Fish Count Events (GAFC) over 10 years ago. Club member and leader of their REEF programs, Kari Larson, says "The club has always been interested in ways to help the environment and help divers understand their role as underwater ambassadors. As a club we promote fun and safe diving. The GAFC was a perfect fit." After learning about the GAFC, she and fellow club member and husband, Mike Davis, thought it was "a good fit for the club and sounded fun. It gave us a chance to contribute to ocean conservation." Ten years later, they are still at it. The club has scheduled 3 upcoming ID classes and a survey dive at Lover Point Park in Pacific Grove, CA (details below). Kari and Mike feel that as a grass roots effort, REEF helps promote involvement at even a beginner diver level and that is important. Kari also noted that, "The access to the database is important, it allows our divers to see how their efforts make a difference. The online resources help members not only in our home area but as they travel to different locations they can identify the fish there also". Club members have started participating in REEF's online Fishinars and the club offers Level 2 & 3 REEF experience testing.

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 John Wolfe. John joined REEF in 1998 and has conducted 530 surveys. John is a member of the REEF Advanced Assessment Team in both the Pacific Coast and Hawaii. In addition to his active survying, he has delved into teaching about REEF and ID and has mentored several surveyors to become experts. He has also taken a keen interest in getting REEF data used by the scientific and management communities, serving on Marine Life Protection Act committees and has written several papers using REEF data. Here's what John had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I took my first REEF fish ID class in 1997. It was a Great American Fish Count kick-off event organized by Karen Grimmer of NOAA and taught by Dan Gotshall (author of Pacific Coast Inshore Fishes). My friend Rachid Feretti was the area’s most enthusiastic REEF surveyor at that time. Quite the raconteur, Rachid would pigeonhole anyone (including curious tourists) to describe the REEF diver survey program. In the late 1990’s I only did a handful of surveys every year, thinking of them as special dives with special equipment; I was also a volunteer diver for the sheriff’s department, diving black water and not getting to the ocean as much. In the new millennium I realized that it was more fun to conduct a REEF survey on EVERY ocean dive I did. That was the big break-through. When I realized I could simply put my slate on a retractable harness and tuck it under my BC belly strap, it became a standard piece of my diver gear, taken on every dive.
If you have been on a REEF Field Survey, where and what was your trip highlight?
Since 2003 I’ve participated in every annual REEF Advanced Assessment Team monitoring project in Monterey, my local dive area. It’s always a fabulous assemblage of skilled cold-water divers and enthusiastic fish nerds, with Captain Phil Sammet entertaining us with salty stories and Christy and Brice Semmens calmly and expertly leading the trips. I’ve been on the Sea of Cortez and Big Island of Hawai’i REEF trips once each, and totally enjoyed both experiences, learning a whole new ecosystem of species.
What is your favorite part about being a REEF member?
REEF totally supports my chosen hobby. My father was a fanatic fly fisherman and my mother is a fanatic bird watcher. It’s only natural that I became a fanatic fish watcher. My REEF experience has also taken me beyond just carrying a slate. Between 2005 and 2007, I served as a diver stakeholder and REEF volunteer representative for the California Central Coast Region Marine Life Protection Act initiative. After three years of intense wrangling between conservation and fishing interests, that effort resulted in a network of Marine Protected Areas along the central coast. In the Monterey Peninsula area we fought so hard that the chairman of the Fish and Game Commission, witnessing the debate, called it the Balkans. Nevertheless, I think the contentiousness of that process led to a resulting network of MPAs that all sides now grudgingly admit is a good compromise.
I have also enjoyed teaching others about REEF and ID. Over the past decade I’ve also given several REEF fish ID classes and presentations about the Marine Life Protection Act Initiative to local divers. I’m always looking for that next special diver who will become an enthusiastic and dedicated REEF surveyor. I have found some special people, like Keith Rootsaert and Alex Matsumoto, who now teach REEF fish ID classes and carry on the tradition.
In your opinion, what is the most important aspect of REEF’s projects and programs?
It’s only now, with fifteen years of data in Monterey, and even more in the western Atlantic, that we’re starting to see the value of the REEF surveys as long term data. REEF scientific advisor, Dr. Brice Semmens, points out that such long-term data are quite rare and precious in ecological research. Furthermore, I think we’ve recently made a big breakthrough on how to statistically analyze the data; it’s a gold mine that we’ve only really started to dig into. I’m really excited about a paper I’m co-authoring with REEF Director of Science, Dr. Christy Pattengill-Semmens, about this topic.
Do you dive close to where you live, and if so, what is the best part about diving there? Where is your favorite place to dive?
The Monterey Peninsula is a special place, with rocky reefs, protected coves, and amazing kelp forests. It’s a two-hour drive from my home in Berkeley, well worth the effort. My favorite dive spots along the Monterey Peninsula include North and South Monastery, now protected in the recently expanded Pt. Lobos marine reserve, as well as Point Lobos State Park itself, the longest running no-take marine reserve in the state. Butterfly House and Point Pinos are wild, spectacular shore dives. I also enjoy the mellower Coral Street and Otter Cove dive sites – and I’ve never had a dull dive at the most heavily dived site of our area, the Breakwater. My favorite local boat dive site is Dali’s Wall outside of Stillwater Cove – it’s always a highlight of our annual Monterey field survey.
What is your favorite fish or marine invertebrate?
Do I have to choose? Kelp Greenling, both male and female, are such handsome fish. Juvenile Canary Rockfish are tiny spectacular gold, black and white jewels. Enormous schools of tubesnout threading and weaving their way through a kelp forest is a spectacular sight!
What is your most memorable fish find and why?
Well, I have a few. I’ve only seen one Rockhead Poacher, years ago – it’s a bizarre tiny fish with a punctured pate (pit in the top of its head) that looks just like the orange cup coral it so successfully hides amidst. It's so bizarre, an exciting find! The second would be finding (and eventually photographing) the Masked Prickleback. It is a handsome fish with a tan back, white belly, and broad dark chocolate brown stripe running the length of the fish from eye to tail. This species was only discovered by science in the mid-1960’s, by a night diver at the Monterey Breakwater. That diver, David Powell, later became the Director of Live Exhibits at the Monterey Bay Aquarium. He recounts his discovery of that species in his book “A Fascination for Fish”. Masked Pricklebacks are shy and nocturnal, relatively uncommon and very difficult to photograph. And finally -- an instance of fish ID rookie vindication! On my first Sea of Cortez REEF field survey, I’d made a couple of embarrassing and very public rookie ID goofs early in the week. So later in the week, after coming up from Swanee Reef and telling Brice I’d seen an Acapulco Damselfish, he was certain I’d seen the much more common Cortez Damselfish … until I showed him the photographic evidence. It was the first (and perhaps the only) Acapulco Damselfish the group saw that week.
