My husband and I recently joined 10 other REEF volunteers on a Field Survey to Akumal, Mexico. Akumal is located on the Mayan Riviera, quite near the Mayan ruins at Tulum, and about 60+ miles from Cancun, Mexico. Our time was filled with diving and conducting REEF surveys, fish identification seminars, exploring cenotes, and learning about sea turtle nesting research.
We stayed at Gran Bahia Principe Resorts, part of an international resort group, which is really 3 resorts in one and covers an enormous acreage on the ocean. The area was so large that one had to catch one of the resort’s trams to travel from one place to another. Sunny weather is the norm that time of year and we had no rain the entire week.
One of the interesting geographic features in this part of Mexico is the cenote, a type of sinkhole which connects to subterranean bodies of water and sometimes cave systems. The rainwater which fills the cenote is crystal-clear because it has been filtered through rock substrata and contains very little particulate matter. The REEF group had the opportunity to dive and snorkel several of these cenotes when ocean conditions turned too rough for dives on the reef, and it proved to be an amazing and unique experience! Since freshwater and salt water are both found in some cenotes, REEF divers surveyed some unusual fish, and experienced the sensation of diving through a halocline, a region below the surface of a body of water where there is a significant change in density due, in the case of cenotes, to increased salinity. Many of the divers described the experience of ascending from salt water into fresh as akin to a dream state. –“The fresh water was so clear, it was hard to believe I was still underwater!" Strange and unusual formations in the caves accentuated the dreamlike atmosphere. Illuminated only by divers’ lights, stalagmites, stalactites and columns stirred the imagination. Fish, bats and birds find a sanctuary in these caves.
Another unique element of Bahia Principe was a local environmental group, Eco-Bahia, whose members work with the resort to help preserve the stands of coral and other sealife found off the beaches. Eco Bahia’s representative, Diana Garcia Urrutia, explained to REEF members all the goals of their program, including the preservation of sea turtle nests. Many sea turtles, mostly Loggerheads and Hawksbills, return to Bahia Principe’s beaches each summer to dig their nests and deposit their eggs. Members of Eco Bahia along with community volunteers protect the turtles as they nest, then collect the eggs and rebury them in a safe, fenced environment just off the beach. When the baby turtles begin to dig out, Eco Bahia volunteers gather them up and bring in local school children who name each baby and send it safely out to sea with a kiss and a blessing. What an excellent way to assure that younger generations will have an emotional connection to the wildlife of their area!
The Akumal Field Survey was certainly a pleasurable and enlightening experience!

Two of REEF's Charter Members, Douglas and Jane Rorex, recently returned from their annual dive vacation to Bonaire. Of course they conducted REEF surveys, documenting the rich fish diversity that is found on Bonaire's reef. But they also each made milestone dives during the trip. Douglas conducted his 3,000th dive and Jane conducted her 700th dive! Both were given medals from the dive resort and Ned and Anna DeLoach, who were in Bonaire for their annual Marine Life Education Program, signed their log books. Douglas and Jane have been with REEF since the beginning -- they are REEF Members 25 and 26. They participated in one of the very first Field Surveys that was held in May 1994. Douglas is a member of the REEF Advanced Assessment Team and has conducted over 350 surveys; Jane has conducted 85 surveys.
Douglas and Jane greatly enjoy their annual trip to Bonaire -- this was their 15th year! Some of their favorite fish finds include the common but always beautiful juvenile yellowtail damselfish as well as the more cryptic frillfin goby and candy basslet. Douglas also conducts surveys on deep reefs in Bonaire (140 feet+), where he finds sargassum triggerfish and striped grunt. Bonaire is also a great place to find frogfish. One of their favorite frogfish stories is about two frogfish that they found on a large coral head at the dive site Windsock. The female had been there for several weeks and was getting larger by the week (obviously ready to mate). One day as Douglas and Jane were hovering nearby, a smaller male frogfish came from underneath the coralhead, waddled over next to her and sort of nuzzled her. She responded by taking her left pectoral fin and giving him a perfect stiff arm. She really smacked him. The rejected male made a hasty somewhat dazzed retreat back to the underside of the coral head. Douglas looked up at Jane to see her practicing the stiff arm manevaure and considering adding it to her repotorie.
Congratulations Douglas and Jane!! Thank you for your enduring support of and involvement with REEF.
REEF's Pacific Northwest Advanced Assessment Team (AAT) gathered in mid-August to survey fish and invertebrate life in the Olympic Coast National Marine Sanctuary (OCNMS). Twelve divers conducted over 120 REEF surveys in the week-long project on Washington's northwest coastline, gathering data to add to the previous 7 year's worth that the project has generated. Twelve sites were surveyed by the divers. The Sanctuary is home to many colorful fish and invertebrates and is a popular spot for sport diving. It is also a popular spot for fishing and there is concern that biodiversity has been diminishing in the area, especially in some species of long-lived rockfish such as Tiger and China Rockfish. Data collected by the AAT will be helpful in tracking these population trends.
Members of the OCNMS REEF survey team were treated to a great week of diving and lots of exciting sights in this remote and wild part of Washington State. Whales were seen every day. Basket stars and giant pacific octopus were encountered by many. And about half the team conducted an optional night dive to remember off of Tatoosh Island in the open Pacific surrounded by Stellar Sea Lions. Projects like the annual OCNMS monitoring are a great way for active REEF volunteers to apply their skills and expertise. These projects are also just one more reason for REEF surveyors to improve their identification skills and increase their survey experience level.
A big thank you to the participating AAT members: Claude and Janna Nichols, Ron and April Theod, Jeanne Luce, David Jennings, Greg Jensen, Todd Cliff, Nick Brown, Pete Naylor, Lorne Curran and Stan Kurowski. Thanks to Mike Furguson and his great crew at Porthole Dive Charters and to Winter's Summer Inn for supporting the project. Funding for the project was provided by The Sustainable Path Foundation and The Russell Family Foundation.Share on Facebook
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. Earlier this month, we had researchers and volunteers in the field for two weeks to conduct field research on spawning aggregations in Grand Cayman and Little Cayman. The site on Little Cayman represents one of the largest known remaining aggregations of Nassau grouper; our research will provide valuable guidance to both the Cayman Islands government and others throughout the Caribbean on how to best protect this important coral reef fish.
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 followed the discovery by fisherman of 7,000 aggregating Nassau grouper on the west end of Little Cayman in 2001 and the subsequent harvest of 4,000 of those fish over two spawning seasons. At the time, all other known Nassau grouper aggregations in the Cayman Islands had become inactive due to over-harvest. Thanks to a three-year grant awarded in 2008 by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF is conducting research through the Grouper Moon Project to evaluate the current status of the Cayman Islands spawning aggregations and the effect of these harvest protections -- “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”.
The broad goals for the 2010 spawning season were to continue monitoring recovery in the large spawning aggregation on Little Cayman, and to expand research into the fate of remnant spawning aggregations on Grand Cayman; aggregations on this island were fished to exhaustion in the recent past. REEF continued education and outreach efforts through public talks about spawning aggregations and the Grouper Moon research. As the sunset provision on the current legislation nears, REEF is working closely with the Cayman Islands government to translate the findings from our research into effective long-term protections. I spent time with the Honorable Mark Scotland, the Minister of Health, Environment, Youth, Sports & Culture, which oversees the Department of Environment in the Cayman Islands, discussing the project, our ground-breaking results, and recommendations for the future of this iconic species.
2010 Aggregation Season Results Summary
The Little Cayman team continued the long-term monitoring of this aggregation, which includes counting the number of fish that show up, estimating the size of the fish, and recording the timing and amount of spawning observed. The REEF research team uses lasers mounted on a video camera to record sizes of fish. If you would like to see what the Little Cayman aggregation looks like during the day, check out this video on YouTube. You will see the laser marks on the fish. Note that these are all Nassau grouper, just in different spawning colors. The team estimated that the number of fish showing up at the aggregation is approaching 4,000. We are also seeing a decrease if average size, which indicates that younger fish are starting to show up (good news!). Spawning was observed on four consecutive nights, starting 4 days after the full moon.
The Grand Cayman team’s primary goal was to document the remnant Nassau grouper aggregation on the East End of Grand Cayman and hopefully observe spawning. The status of this aggregation was initially documented by a Grouper Moon team in 2009. This year, with a lot of help from our partners at CIDOE and Wayne Sullivan and his crew aboard the Glen Ellen, REEF volunteer Denise Mizell was able to head up this critical component of our research. While several hundred fish were found at this historical spawning site, spawning was not documented. Unfortunately, we believe that fisherman were illegally fishing on the aggregation when our team was not on site. It is possible that this disturbance prevented the fish from spawning. This is disappointing news, but we are hopeful that the Cayman Islands government will pass revised legislation and provide more enforcement before next spawning season in order to protect the few remaining Nassau grouper on Grand Cayman.
Why Does This Matter?
Nassau grouper are not just icons of the Caribbean; they are a social and ecological cornerstone of the region’s coral reefs. Historically, Nassau grouper represented one of the region’s most economically important fisheries. Unfortunately, due to intense harvest on spawning aggregations, their populations have dwindled to a fraction of their historic numbers. The species became the first Caribbean reef fish to be listed as endangered by the International Union for the Conservation of Nature (IUCN) and the species is candidate listed under the US Endangered Species Act. The precipitous decline in mass spawning aggregations of Caribbean grouper species has been well documented. The majority of known Caribbean aggregation sites are now inactive due to the ease with which aggregating species are caught. And those that are still active contain significantly fewer fish than the 10s of thousands that historically gathered at these special places.
As part of our work on the Grouper Moon Project, REEF will continue to develop a comprehensive assessment of the status of the Cayman Island’s Nassau grouper spawning population as a guide for future Nassau grouper restoration and conservation policy.
Collaborators and Supporters Who Make This Project Possible
REEF would like to thank our collaborators at the Cayman Islands Department of the Environment, specifically Phil Bush, Bradley Johnson, Croy McCoy, James Gibb, Tim Austin, Gina Ebanks-Pietre, Keith Neale, Delwin McLaughlin and Robert Walton, as well as Drs. Scott and Selina Heppell from Oregon State University. REEF Volunteers have always been at the core of our Grouper Moon field work and 2010 was no exception – heartfelt thanks to Heather George, Steve Gittings, Denise Mizell and Sheryl Shea. The support and assistance of Thor Dunmire is also greatly appreciated. The Grouper Moon Project has continued through the years empowered by the first year’s success and the passion of early project leader Leslie Whaylen Clift. Assistance from OSU graduate student, Stephanie Kraft Archer, is much appreciated. Principal financial support is from the Lenfest Ocean Program of the Pew Charitable Trusts and the CIDOE. Additional funding is from Mr. Wayne Panton, Mr. Dan Scott, Clive and Stella Wood, Franklin and Cassandra Neal, and hundreds of REEF members. Continued in-kind logistical support from island businesses and residents, including the Little Cayman Beach Resort/Reef Divers, the Southern Cross Club, Peter Hillenbrand, Dottie Benjamin, and Judie Clee is also much appreciated. To alleviate the constraints of diving deep depths on regular scuba, several other sponsors came on board to assist in the project, including Divetech and PM Gas of Grand Cayman, Silent Diving of Brockville, Ontario and Shearwater Research of Vancouver, British Columbia.
And finally, our work on Grand Cayman would not have been possible without the generous support of Wayne Sullivan, who donated his vessel the Glen Ellen, his time (and patience), his equipment and technical diving expertise, and his crew, Brady Booton and several others.

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.
