The Faces of REEF: 2011 Volunteer of the Year, Heather George

REEF proudly names Heather George as our 2011 Volunteer of the Year. Since becoming a member nearly a decade ago, Heather has conducted 192 REEF surveys throughout the world and is a member of the Advanced Assessment Team in the Tropical Western Atlantic and Hawaii. In 2010, Heather joined the volunteer research team for the Grouper Moon Project. Through the years, she has conducted fish identification trainings for dive shops and aquaria and has led several REEF Field Survey Trips. Heather also served on the REEF Board of Trustees from 2007 to 2010 and brought a wealth of knowledge about fundraising and membership development to the organization. In 2011, Heather assisted with the expansion of the Volunteer Fish Survey Project to the South Pacific as part of the field team to American Samoa. When Heather is not underwater looking at fishes or teaching others about the joys of fish watching, she is helping other ocean-related organizations such as the Aquarium of the Pacific and the Waterkeeper Alliance. We are so grateful to have a wonderful volunteer who contributes to REEF in so many ways. Thank you, Heather!

Outstanding in their Field: Featured REEF Field Station, Scuba Obsession

REEF is proud to partner with over 270 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations. For more information on how to find one near you, or to become a Field Station in your area, visit the Field Station Directory.

This month we feature Scuba Obsession, Al Audet's independent instruction business located in Melbourne Florida. Al was introduced to the wonderful world of fish identification through a class through OceanWatch.org. He attended as many classes as he could, and through the help of outstanding instructors and guides, he was hooked. He decided to incorporate fish ID into his teaching repertoire, and signed up as a REEF Field Station in November 2009.

Instructors have a lot of influence on their new open water students, and Al steers them toward fish ID all along the way. During the last Open Water dive, he normally takes his waterproof Fish-In-A-Pocket guide and points the fish they see on their dive out to the students. As his students move on to their Advanced Open Water courses (of which they can choose some that match their interests), he always encourages them to select Fish ID as one of their Adventure Dives. During the class, they learn about fish ID, do REEF survey dives together, and then are encouraged to join REEF and enter their data.

Al feels that the east coast of Florida is a great place to engage divers in fish ID. "The east coast of Florida has some of the best diving in the world. You never know what you're going to see. We also have the most popular muck dive in the world - the Blue Heron Bridge. You'll find fish under the bridge that you won't see any place else in Florida."

Al employs several different teaching techniques for his students. He offers Fish ID classes regularly and also attends REEF Fishinars, which he touted as one of REEF's best programs. He has also put together a video for his Fish ID students, online and available for viewing here: http://vimeo.com/11153948

One of Al's most exciting moments during a dive was when he was teaching a Fish ID Adventure dive for an Advanced Open Water class off Jupiter, FL. The boat captain gave them a sand drop, so after a few minutes of looking for the reef, the dive guide decided to ascend. On the way up... they looked up, and realized they were ascending into a whale shark! One of Al's students described it best, "I looked up, and I thought I saw the boat. Then I saw the fins." Thanks Al and Scuba Obsession for serving as a REEF Field Station!

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

On August 13th, Lad Akins, lead on REEF's lionfish efforts, was an invited presenter to the Caribbean Fisheries Management Council and other meeting attendees at its bi-monthly meeting in St Croix, USVI. The council is charged with advising the National Marine Fisheries Service on regulations and issues related to commercially valuable marine life species in Puerto Rico and the USVI of St. Thomas, St. John and St Croix. 

Based on recent information coming from REEF's work in the Bahamas, the Council expressed great concern over the impending spread to the US Caribbean and beyond and what might be done to best address the invasion. Lad presented the current state of knowledge on the invasion and research results from REEF's collaborative efforts with NOAA, the USGS, the National Aquarium in Washington, Simon Fraser and Oregon State Universities, and REEF volunteers. Following the presentation, and numerous questions from members of the audience, the council made plans to further address the invasion with continued dialogue with REEF and initiation of a technical workshop to develop recommendations for the council.
