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:

- A researcher from University of British Columbia is using REEF data to evaluate the efficacy of marine reserves in Canadian waters.

- A researcher from Florida State University has requested REEF data to study Goliath Grouper populations in Florida.

- A student at Coastal Carolina University is using data to study fish populations at Discovery Bay in Jamaica.

- Scientists from NOAA Fisheries and Scripps Institution of Oceanography are using data from multiple monitoring programs, including REEF, to evaluate new methods of evaluating population trends in fisheries.

Putting It To Work: New Publication on Nassau Grouper Populations in the Caribbean

REEF Grouper Moon scientists co-authored a recent groundbreaking paper in the journal PLoS One that highlights the importance of regional conservation efforts aimed at spawning aggregations in the Caribbean. This study evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean using DNA markers. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean. These results suggest that, despite a lack of physical barriers, Nassau Grouper form multiple distinct sub-populations in the Caribbean Sea. Oceanography (regional currents, eddies) likely plays an important role in retaining larvae close to spawning sites at both local and regional spatial scales. These findings highlight the importance of conservation initiatives such at REEF's Grouper Moon program in the Cayman Islands. A PDF of the paper is available online here. You can see a complete list of all scientific papers that have included data from REEF programs at www.REEF.org/db/publications.

If you’ve read recent REEF releases, you’ve heard the news that Indo-pacific lionfish are now well established along the eastern US coast and throughout the Bahamas. REEF has been and continues to work with researchers to learn as much as we can in order to most effectively address the invasion. Since January of this year, REEF has organized and led 5 week-long projects in the Bahamas to document the extent of the invasion and gather samples and information needed by NOAA and Bahamian researchers.

 
Here is what we’ve found:

  • Lionfish are being found as deep as 350’ and as shallow as 2’.
  • Lionfish have been documented in almost all habitat types including patch reefs, artificial reefs, walls, and even mangroves
  • Lionfish have been captured as small as 25mm and as large as 389mm
  • Most lionfish have been in the 200mm size range
  • Lionfish prey has included fish, shrimp and crabs
  • Lionfish appear to have high site fidelity (they don’t move much)
  • Lionfish appear to be reproducing year-round in Bahamian waters
  • The lionfish invasion appears to have come from a small founding population (not a large release of many fish)
  • Stomach content analysis has documented lionfish predation of cleaner fish
  • Every site visited in the Berries in April contained lionfish – most contained multiple fish

 
Here is what we are working on with NOAA and Bahamian researchers:

  • Continuing documentation of lionfish distribution and impacts on local fish populations
  • Documentation of lionfish at cleaning stations and subsequent predation on cleaning fish
  • Predation by other species on lionfish
  • Genetic relationships of lionfish in one area (NC, northern Bahamas) to those in other areas (S Bahamas) to determine dispersion pathways.
  • Parasitology of lionfish (they appear to have few parasite compared to native fish)
  • Larval occurrence at different locations using larval light traps
  • Juvenile recruitment preference using small shallow water nets and trawls
  • Trap preference of adult lionfish
  • Lionfish recruitment rates to sites denuded of lionfish (i.e., recruitment pressure)
  • Recruitment of lionfish to artificial structures
  • And more!

As part of this effort, REEF has planned more research efforts through the end of 2007. Each project will include participation of scientists, researchers, and/or REEF staff. For a list of upcoming projects visit http://www.reef.org/exotic/lionfish/ or e-mail lad@reef.org

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 joe@reef.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!

Bigger Than Ever - Lionfish Research Continues

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:

 

  • Lionfish continue to grow in size: Tagging data are showing growth rates exceeding 190mm/year.  This is far larger than necessary to reach sexual maturity.
  • Site Fidelity: All 12 tagged specimens that have been recaptured indicated strong site fidelity even after 6 months.
  • Prey: Lionfish continue to amaze us during our stomach content studies. This May effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. The lionfish are eating nearly anything that will fit into their mouths.
  • Reproduction: Lionfish reproduction continues to occur throughout the year – we found many gravid females and a small recently settled juvenile.

 

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. For additional information, please contact Lad Akins at (305) 852-0030 x-2# or e-mail Lad@reef.org

Taking A Dive Trip That Counts

As Fall is upon us, we look ahead to 2009 and a great lineup of REEF travel opportunities. Our partners at Caradonna Dive Adventure have helped us put together an exciting Field Survey schedule, including St. Croix, Bermuda (with Ned and Anna DeLoach), and Grenada on the Peter Hughes Winddancer (with Paul Humann). These week-long projects are led by experts in fish identification and include great diving, learning, and camaraderie with like-minded divers and snorkelers. Your non-diving companions are welcome on all of the land-based projects. There will also be several Lionfish Research Project expeditions, which allow participants to get first hand experience in this exploding invasive species issue. Be sure to check out all of these trips, posted online at http://www.reef.org/fieldsurveys/schedule. And remember that it's not just on REEF Trips that you can Make Dives That Count! You are encouraged to conduct surveys during your personal dive vacations farther afield and on local weekend dives in your own backyard. Be sure to order survey materials through the REEF Online Store before you leave and check out what species you are likely to see with the Geographic Summary Reports. And while you are waiting for your tank to be filled, it's fun to tell the folks at the dive shop what you are doing. Being a REEF ambassador helps spread the word about the Volunteer Survey Project and the value that fishwatching adds to your experience in the water. We hope that you will join us in making dives that count in 2009. We are kicking off the year with a Field Survey to St. Lucia led by new REEF Executive Director, Lisa Mitchell. To find out more or to book your space, please contact our dedicated travel specialist at 877-295-7333 (REEF), REEF@caradonna.com. And be sure to download our 2009 Trip Flyer!

REEF staff, volunteers and friends at the REEF booth -- Jane Bixby, Tom Wells, Maurine Shimlock, Kay Wells and Burt Jones

Once again, REEF participated in the dive industry show, DEMA. We showed off all of the cool REEF gear, including our new lionfish t-shirts, which were a hit, as well as all of the REEF survey essentials. We also spoke with many dive instructors who were looking for new types of classes to teach. The REEF Fish ID curricula certainly fit the bill. A lot of networking was done and new friends made. And lots of people signed up for a free REEF membership. Thanks to generous sponsorship by Sherwood Scuba, we were able to host visitors and spread the word about REEF in a large double booth. As always, we couldn’t have done it without the help of several REEF volunteers. A big thank you goes to Jim and Mary Jo Davis, Robyn Churchill, Tom and Kay Wells, Lureen Ferretti, Deb Deavers, Beth Olsen, Andy Dehart and Park Chapman for all of their help at the REEF booth. Paul Humann and Anna DeLoach also spent a considerable time in the booth, to the delight of the dive community that happened to pass by! All in all, a truly enjoyable experience!
