A new publication in the scientific journal Coral Reefs was recently issued based on science conducted as part of REEF's Grouper Moon Project. The paper, titled "Hydroacoustics for the discovery and quantification of Nassau grouper (Epinephelus stratus) spawning aggregations", summarizes results from work conducted during the 2014 Grouper Moon Project field season in the Cayman Islands. Led by Jack Egerton from Bangor University in the UK, the research focused on the use of hydroacoustic technology as a means to monitor the status and ecology of fish spawning aggregations. Egerton was assisted by Grouper Moon scientists, Dr. Brice Semmens and Dr. Scott Heppell, as well as Grouper Moon collaborators from the Cayman Islands Department of Environment. Using a split-beam echo sounder, data were used to visualize and estimate fish abundance and biomass at three Nassau Grouper spawning aggregations in the Cayman Islands. The estimates were compared with diver-collected data. Additionally, the technology was used to examine fish aggregation locations in relation to protected zones.

Patterns in the acoustic abundance matched that observed by the visual estimates reported by our Grouper Moon diver teams - total numbers found at the Little Cayman aggregation were significanly higher than the depeleted aggregations found on Grand Cayman and Cayman Brac. 

Spawning aggregation location examined with reference to seasonal marine protected areas (Designated Grouper Spawning Areas) showed that the aggregations were partially outside these areas at Grand Cayman and very close to the boundary at Cayman Brac. The aggregation on Little Cayman appears to be contained within the protected zone (at least in 2014). However, we know from other Grouper Moon Project data that the fish spend a lot of time traveling in and out of the zone during the day. Additionally, in 2015, the aggregation on Little Cayman shifted a significant distance to the north of the historical location and partially out of the protected zone. The results of this study show the importance of making use of many different approaches for monitoring and aggregations in order to most effectively inform future management of aggregating fish species.

Passion for the Cause: REEF's Legacy Society

Rosette Davila is leaving her legacy for the oceans through a life estate gift to REEF.

Rosette Davila cares deeply about the health of the oceans. As a supporter of REEF programs both in the water and on land, Rosette wants to make a difference. That's why she recently became part of REEF's Legacy Society through a life estate gift. When asked why she chose REEF, Rosette described a long history of diving (since 1993), where she has become increasingly alarmed with the deterioration of our oceans. In 2015 Rosette joined REEF's Lad Akins and Peter Hughes on a REEF Invasive Lionfish Research Trip to The Bahamas. Her experience removing lionfish, during that trip and subsequently in the Turks and Caicos, opened her eyes to how beneficial REEF's citizen science programs can be. Rosette is determined to do whatever it takes to help REEF in their efforts, as she has seen firsthand the positive results of the work REEF does.

Rosette recently retired from her family's pharmacy in Texas and has relocated to Spain. As she was settling her affairs, she contacted REEF to request a letter of intent indicating her wishes. We are so grateful for Rosette and the other members of REEF's Legacy Society.

Panel Discussions Bring Citizen Scientists Together in the Florida Keys

On Tuesday, February 26 and Wednesday, March 12, REEF hosted two citizen science panel discussions about how volunteers contribute to understanding and preserving the Florida Keys environment. The first discussion, held in Key Largo, featured speakers from the Breeding Bird Survey project, Coral Restoration Foundation, and John Pennekamp State Park native plant nursery. The second event, held in Key West, featured speakers from The Nature Conservancy, Mote Marine Laboratory and the National Weather Service. Both discussions were led by guest speaker Rick Bonney, a pioneer in the citizen science field from the Cornell Lab of Ornithology in Ithaca, NY. Leda Cunningham presented on the REEF Volunteer Survey Project.

Forty-two people participated in the discussions, most of whom were themselves volunteers in a local or national citizen science project. "Most scientists usually only get to attend 'niche' meetings, where everyone in the room is talking about variations of the same subject matter," said Alison Higgins of The Nature Conservancy. "What was amazing about REEF's Citizen Science symposium is that the approach was the same (engaging the public in collecting important observations), but the subjects were varied.  I specialize in land conservation issues, but got to brainstorm and engage with fish, bird and weather scientists - It was a really great and necessary experience"

Each discussion group brainstormed next steps for the citizen science movement in the Florida Keys. Ideas included forming an informal coalition of citizen science projects, doing integrated data analysis across project taxa (effect of weather on fish or bird population trends, e.g.), starting a regular citizen science column in a local newspaper and developing a citizen science booklet for residents and visitors to learn about local projects. For more information, please contact Leda Cunningham: Leda@REEF.org.

 

REEF Hosts ICRS Field Trip

2008 International Coral Reef Symposium Field Trip in Key Largo
11icrs_header_logo.jpg
11th ICRS Hosted 100's of Talks and Had Over 3,000 Attendees

In addition to attending the 11th ICRS, REEF also hosted one of the conference Field Trips.  REEF and Horizon Divers hosted 14 participants from various locations around the world including Australia, Japan, Kenya, and several U.S. institutions.  Dr. Jim Bohnsack, NOAA Research Fisheries Biologist and Science Advisor to the REEF Board of Trustees, gave a workshop presentation on applying REEF fish survey data towards Florida Keys National Marine Sanctuary management decisions and Paul Humann, renowned marine life photographer and author, taught fish and invertebrate identification classes.  Lad Akins, REEF Special Projects Director, gave an overview of REEF and our programs along with a detailed update on what he and REEF partners are working on with the Lionfish (Pterois volitans) invasion in Florida, the Bahamas and Caribbean islands. Participants also had the opportunity to conduct 6 REEF survey SCUBA dives out on our local reefs to get a sense of how Roving Diver survey data are collected.

The survey data our members collect fall into two general categories.The first is the Volunteer Survey Project category that includes all of our Field Surveys and individual members surveying efforts conducted while diving or snorkeling wherever they live or travel to on vacation. The second type of data collected by our surveyors are from our monitoring and research programs in partnership with NOAA sanctuaries, the National Park service, and regional NGO’s and other non-profits as well as various universities.  It was this second category of data that our ICRS Field Trip focused on for classroom discussions. REEF data are used by resource managers include artificial reef monitoring, restoration site monitoring, marine protected area assessments, and invasive species collections and fish surveys to name a few.  One message that ICRS brought home to all attendees is that now more than ever, there is a critical need for coral reef related research, including studies addressing fish assemblages. There is also a critical need for scientists and policy makers to communicate their research and conservation strategies to the general public, conveying the message about just how vulnerable coral reefs are to anthropogenic disturbances and their importance to our collective well being. REEF will continue our efforts to engage our membership in worthwhile conservation projects that address tropical and temperate fish assemblages.
