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
Winter full moons mean that it's grouper spawning time! Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort with the Cayman Islands Department of the Environment (CIDOE) aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species. Our research focuses on Little Cayman, which has one of the largest (and one of just a few) known remaining aggregations of Nassau grouper in the Caribbean. We estimate that between 5,000 and 7,000 Nassau grouper come to the site to spawn. Thanks to funding from the Lenfest Ocean Program of the Pew Charitable Trusts, NOAA Coral Reef Conservation Program, and the Disney Wildlife Conservation Program, REEF and our partners at CIDOE and Oregon State University have used state-of-the-art technology, as well as good old fashioned diver surveys, and the research has yielded ground-breaking results. In 2003, the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all known aggregation sites in the Cayman Islands (both current and historic). This ban expires later this year and new legislation is being developed. We are rapidly compiling the results of our research, which will provide the Cayman Islands government guidance on how to best protect this important coral reef fish.
Earlier this month, we had a small team in the field- Dr. Selina Heppell (OSU researcher), Stephanie Archer (OSU graduate student), and Brenda Hitt (long-time REEF Grouper Moon volunteer). They witnessed spawning on two nights following the January full moon. We expect February to be the "main" spawning month (based on past research, we know it has to do with when the full moon is in relation to the winter solstice). A much larger team of researchers and volunteers will be on the island to conduct a full suite of research projects. We will also be producing several outreach products aimed at promoting the management and conservation of these spawning aggregations. Stay tuned for more information on this exciting and important marine conservation research. In the mean time, to find out more, visit the Grouper Moon Project Webpage. To see video of the aggregation during the day, check out this video on YouTube taken last year.

This month we feature Patricia Richardson (REEF member since 2000). Pat lives on the Big Island in Hawaii, and is a member of REEF's Hawaii Advanced Assessment Tea. Pat has conducted 778 surveys, and most of these have been done at one site. She has really enjoyed getting to know every critter that lives in her neighborhood spot. Here's what Pat had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
Richardson Ocean Park in Hilo, Hawaii, is near my home – and by chance shares my name. In 2000, I decided I wanted to learn as much as I could about the fish life in this popular beach area with the purpose of keeping a record of species diversity and general ocean health. Not long after I began my project, Liz Foote and Donna Brown came to Hilo to conduct a REEF training session. The REEF survey methods were a perfect match with my personal project! Before I left the training session, I was signed up, tested for Level 2, and hooked! I submitted my first survey dated January, 2001.
If you have been on a REEF Field Survey, where and what was your trip highlight?
Since then I have become SCUBA certified and have participated in four REEF survey trips in Hawaii led by Christy and Brice Semmens. My favorite was the trip to Kauai in August of 2006. I saw my first pair of Tinker’s Butterflyfish, also a Hawaiian Morwong and a Whiskered Boarfish. The last two fish are more common in the remote Northwestern Hawaiian Islands than in our main islands. We were also thrilled to see Hawaiian monk seals on several dives. Another REEF adventure was a trip to American Samoa in 2010 to help REEF extend survey methods into the South Pacific. This was my first chance to do surveys out of my home waters. It was very exciting to see many new species along with familiar “faces” from Hawaii.
What inspires you to complete REEF surveys?
Keeping a close watch on the fish life at Richardson Ocean Park is still my favorite activity. I use mask, snorkel, and fins because the average depth of the area I survey is 4 to 6 feet, with occasional drops to 20 feet if the surf is down. A single survey usually takes about 2.5 hours. After ten years and about 700 surveys in this one small area, I am still amazed each time I enter the water with the constant change and constant beauty I find there. From time to time, something new pops up to keep me alert. Recently it was a Yellowhead (Banded) Moray. And a couple times it was a Hawaiian Monk Seal! Unfortunately, there’s no place on the data sheet for that! I also drive to Kona on the west side of Hawaii Island to dive and snorkel, always with my underwater survey slate in hand.
What is your favorite part about being a REEF member?
My connection with REEF gives me the satisfaction of being a “citizen scientist” and a good excuse to spend several hours each week following beautiful fish around and watching their fascinating behavior. After a decade as a REEF fish counter, I am looking forward to the next decade. It’s the greatest retirement project I can imagine!
