Ground-breaking invasive lionfish findings were featured in a paper published earlier this month in the scientific journal, Ecological Applications. The research was conducted as a collaboration between REEF, Oregon State University, Simon Fraser University, and the Cape Eleuthera Institute. The new study, conducted by Dr. Stephanie Green (OSU/REEF), Lad Akins (REEF), and others, confirms for the first time that controlling lionfish populations in the western Atlantic Ocean can pave the way for a recovery of native fish. Even if it's one speared fish at a time, data are showing that removals can be effective. And not every lionfish need be removed…the research findings document that reducing lionfish numbers by specified amounts will allow a rapid recovery of native fish biomass. Over 18 months, the biomass of native prey fishes increased an average 50-70% on reefs where lionfish numbers were suppressed below target levels predicted to cause prey depletion. On reefs where lionfish numbers remained higher than target levels, the biomass of prey fishes decreased by a further 50%. While complete eradication of lionfish from the Caribbean is not likely, groups are actively removing them from coastal areas (mostly via spear and net). This study is a first step in showing that strategic local efforts that suppress the invasion to low levels can help protect and recover native fish communities affected by lionfish.

The documentary "Grouper Moon", produced by Miami public television station WPBT2's Changing Seas, recently wowed audiences and judges at the Reef Renaissance Film Festival in the US Virgin Islands. "Grouper Moon" was awarded the Neptune Award for Best in Show, and a 1st Place Black Coral award in the Documentary Short category. The episode focuses on the collaborative efforts of REEF and the Cayman Department of the Environment to study and conserve one of the last great populations of the Nassau Grouper. A WPBT team joined REEF in the field during the Grouper Moon Project, chronicling our efforts to help save this imperiled reef fish. You can view the documentary online here.

REEF is delighted to announce our 2014 Volunteer of the Year, Dawn Vigo. As an enthusiastic member for the past 12 years, she has done over 75 fish surveys on Field Survey trips, and is a Level 3 surveyor in the TWA region. In addition, she’s participated in and helped with many other facets of REEF’s programs and outreach efforts.
Dawn has gone to great lengths to help at many dive shows including the DEMA show in Las Vegas and is a big factor in REEF’s success at Our World Underwater show in Dawn’s hometown of Chicago. She enthusiastically explains about REEF’s programs to show-goers and has a never-ending supply of energy.
If you are a regular attendee of our online webinars (Fishinars) within the past two years, you’ll recognize Dawn as a regular behind-the-scenes staff person helping with technical details or answering your questions.
Dawn has also helped administer Experience Level tests to others, furthering the success of REEF’s Volunteer Fish Survey Project. We are lucky and thankful to have a super volunteer who contributes to REEF in so many ways. Thank you, Dawn!
One of the most rewarding and fun aspects of being a REEF surveyor is finding a new species to add to your "Life List" (a lifetime compilation of all fish species seen). Even the most experienced surveyors, after hundreds of surveys, occasionally add new species to this list. Expert Caribbean surveyor, Patti Chandler, recently emailed us about one such find. Despite having over 900 REEF surveys under her (weight) belt, she and her husband Scott recently came across a little mystery while diving in front of CocoView Resort on Roatan - a brilliant blenny with BIG cirri on its head. After emailing the photo to a few experts, they discovered that they had captured what is likely the first in situ photos of the species, and also documented the first record of the species in the Western Caribbean. Not only does their sighting of a Horned Blenny (Paraclinus grandicomis) represent a "lifer" for their lists, it was also a new record for the TWA REEF database. Great find, Patti and Scott!
If you have a First Sighting story to share, email us at data@REEF.org. And did you know? - If you are a REEF surveyor, your Life List can be accessed under the 'My REEF' menu when you are logged in to the REEF website.
Our 2016 Fishinar schedule is in full swing, and we invite everyone to join in the fun of learning fish ID in the convenience of your home, with these energetic and informative online webinars.

Bermuda is at the northern extent of the Tropical Western Atlantic survey region and represents a unique destination for REEF's fish watchers. There are six spaces left on our Field Survey Trip to Bermuda (October 1-8), and this is your opportunity to dive pristine reefs, expand your knowledge of marine life, and search for elusive and beautiful fish such as the redback wrasse. Trip leaders Ned and Anna DeLoach will entertain participants with their fish identification and behavior expertise, providing engaging lectures and photographs in conjunction with educational seminars each evening. Pink sand beaches, fascinating historic sites and a blend of British Colonial and African culture help to make Bermuda, also known as the "Jewel of the Atlantic," a captivating destination for non-divers as well. Check out the full trip description at www.REEF.org/trips.
Even if you can't make the trip, be sure to join Ned and Anna online for their free Fishinar at the end of this month, August 30. See www.REEF.org/fishinars for all the details.
WASH Nearshore Symposium
REEF’s Director of Science, Dr. Christy Pattengill-Semmens, was an
invited speaker at the Temperate Reef Resources Symposium held at the University of Washington in early June. Christy spoke on the role that volunteers play in generating needed data for managing temperate reefs, and used examples from REEF experiences and projects in three west coast National Marine Sanctuaries, the Olympic Coast, Monterey Bay, and
the Channel Islands. To date, over 10,000 REEF surveys have been conducted in coastal areas along the west coast of the US and Canada.
Channel Islands Shore to Sea Lecture Series
In early July, Christy was the featured speaker for the monthly Channel Islands Shore to Sea Lecture Series, which is sponsored by the Channel Islands National Marine Sanctuary and Park. Christy spoke on REEF surveying inside and outside of the marine reserve network that was
implemented around the Channel Islands in 2004. Much of these data are
collected using REEF’s Pacific Advanced Assessment Team aboard the Channel Islands National Marine Sanctuary’s Research Vessel Shearwater.
Flower Garden Banks National Marine
Sanctuary fisheries impact workshop
Christy also presented information on the REEF
Volunteer Survey Program at a recent priority issues workshop on fishing impacts for the Flower Garden Banks National Marine Sanctuary. The workshop was used to discuss the possibility of Flower Gardens National Marine Sanctuary implementing experimental no-take zones within the Sanctuary. Christy presented information about REEF's volunteers 14 year long monitoring of reef fish at the Flower Garden Banks National Marine Sanctuary, and how this data can provide a valuable baseline to be able to measure the effects of any future no-take zones that might be implemented in the Sanctuary.
Here's what we're up to in the coming months:
October 31- November 3: DEMA Show in Orlando, FL. Come visit us at both 1133 and you could win a signed print by Tom Isgar by partaking in our DEMA raffle to help raise funds for REEF.

Once again, CEDAM International is offering two scholarships for educators to participate on a REEF Field Survey. For the 2008 survey season, the scholarships will apply to the Gran Bahia Principe Field Survey in Akumal, Mexico. Dates for this trip are May 17-24, 2008. You can visit REEF's Field Survey page to view trip details and also check out the trip flyer. To apply for this scholarship, please visit the CEDAM website at then click on the Lloyd Bridges Scholarship tab at the top of the page to see details.
The two scholarships enable qualified educators to participate - at no cost - in a CEDAM-sponsored or -sanctioned expedition. This REEF Field Survey will be led by Joe Cavanaugh, REEF Field Operations Director. Participants will have the opportunity to collect data, participate in daily talks, and interact with REEF members, staff, and local organizations. This will be a hands-on experience during which participants have the opportunity for fish identification and marine conservation training in and out of the water. REEF has partnered with ReefAid and Reefcheck and Ecologica Bahia in 2007 to assist Gran Bahia Principe Resort with developing a monitoring and assessment protection plan for their nearshore reefs. Our cooperative efforts in conservation at Bahia Principe are making a difference in protecting their reefs and some of our class time will focus on these successes.
To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization.The scholarship will be awarded on the basis of both merit and financial need. CEDAM International will cover the recipient’s airfare and REEF Field Survey expenses (excluding incidentals and personal expenses), on this educational adventure. Bahia Principe is an all-inclusive resort so acoomodation, diving, and meals are included. The application deadline will be earlier than last year's deadline since the Field Survey pariticipation dates are in late May this year. Please have your completed applications submitted by April 1, 2008.
Many of our members may be too young to have seen the television program, Sea Hunt, starring Lloyd Bridges that ran from 1958-1961. One important aspect of the series was that Bridges made a plea at the end of each episode to protect the oceans, an early ocean conservation pioneer. He was also involved in several organizations including the American Oceans Campaign and Heal the Bay, a Los Angeles-based conservation group. He inspired a generation of SCUBA divers and you may want to check out Wikipedia to read more about many of the people Bridges worked with on Sea Hunt. Incidentally, I discovered that Bridges learned to SCUBA dive once contracted for the show and that he was offered the role of Captain Kirk before William Shatner!
There are still spaces (4) available for the Akumal Field Survey, email firstname.lastname@example.org to inquire.
All applicants must complete an application form and return it along with the required essay and two letters of recommendation, to CEDAM (by mail or electronically) by April 1, 2008. Good Luck!
As many of you are aware, the recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the USGS, the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem.
Our most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement. To wit:
To date, dive operators and the contributions of participating volunteers have funded the bulk of this work. REEF’s future field-work will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program.
