Happy St. Patrick's Day! We show our "green" spirit here at REEF by continuing important conservation initiatives. 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.
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.
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 is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
This month we feature Marker Buoy Dive Club in Washington, which has been a Field Station for about a year. The Marker Buoy Dive Club was founded in 1961 and some of its club members have been diving in Puget Sound since the 1960s and 1970s, so they are very aware of long-term changes in some local fish populations. The Marker Buoy Dive Club currently has about 145 members. They have a dedicated group of members who encourage club participation in the REEF program and in other local activities that raise public awareness of the marine life in Puget Sound. The club is very fortunate to have an active REEF Level 5 surveyor (Rhoda Green) who is willing to teach REEF Introduction to Fish and Invertebrate Identification classes.
In addition to offering ID classes, the club hosts survey dives on a regular basis (sometimes as often as once/week) and encourage club members to report their sightings from their own dives. They have added a REEF News section to our monthly newsletter and are featuring a “Critter of the Month” from the PNW Critter Watchers archive. The club will be recognizing the volunteer efforts of members who have been most active in the REEF program and all club members who turn in at least 10 surveys this year will be entered in a drawing for some fun prizes. Some future plans include encouraging members to become advanced level REEF surveyors and to broaden the range of ID classes including Hawaiian fish identification class for club members who are planning to go on a dive trip to Maui. Club members recently remarked "REEF wouldn’t be the program that it is without the efforts and dedication of our regional Outreach Coordinator, Janna Nichols, and all of the people who volunteer their time to teach the classes, host survey dives, log their surveys and report their sightings – keep up the good work!"
Thanks Marker Buoy Dive Club – you’re a shining beacon to us all!
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 used data on yelloweye rockfish frequency of occurrence in the San Juan Islands in Washington to evaluate population status for the San Juan County Community Development and Planning Department.
- The Tunicate Response Action Committee (TRAC) in Washington State evaluated data on three invasive tunicates that are included REEF's Pacific Northwest program.
- A scientist from Florida Fish and Wildlife requested data on yellowtail snapper populations in the Southeastern US to conduct analyses for a stock assessment.

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.
