It's always great to have a buddy to point stuff out to.

REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.

This month we highlight Mary Korte. Mary, and her husband Don, have been REEF members since 2001. Both are active surveyors, and Mary is a Level 3 surveyor in the TWA who has completed 284 surveys (all on snorkel!). Here’s what Mary had to say about REEF:

What is your favorite part about being a REEF member?

Everything! I especially love the Fishinars because they are a great way to improve my fish identification skills, and they boost my confidence in my ability to record species accurately. Fishinars also inspire me to read about the species and learn more about the fish behaviors I observe. I’d love to dive, but I can’t SCUBA dive due to my cardiac history. However, even as a snorkeler, I can contribute to the REEF database. I used to feel bad that I couldn’t dive, but REEF staff members have been wonderful and have told me that reporting data from the top 10-15 feet is important—I’m thankful for their encouragement. I also love that the REEF staff will help me identify “mystery fish” in photos I take while surveying.

If you have been on a REEF Field Survey, where and what was your trip highlight?

My husband and I went on the first lionfish survey REEF organized in Curacao. Curacao is a special place for us because we’ve spent our wedding anniversary there every year for almost 15 years. It’s a wonderful island, and the fish life is amazing. It meant a lot to be able to help gather data on the lionfish invasion and hopefully make a difference in the future of the reef fish populations. Without a doubt, eating those pesky fish was the highlight. As our t-shirts say, “Wanted Dead and Grilled: Lionfish, Pirate of the Caribbean.” They make very tasty ceviche, too! We also loved the wonderful sunset sail the last night.

If you had to explain REEF to a friend in a couple of sentences, what would you tell them?

You’ve probably known birdwatchers who keep a life list of bird species they’ve seen. They may collect data, e.g. by participating in the Great Backyard Bird Count. REEF volunteers are “fishwatchers” who keep a life list of fish and collect data on fish abundance and biodiversity for a global database used by marine biologists to monitor the health of coral reefs worldwide. Over 60 scientific papers have been written using REEF data which is really amazing.

In your opinion, what is the most important aspect of REEF’s projects and programs?

I think the most important aspect is that REEF’s professional staff and volunteer “citizen scientists” are enhancing our understanding of coral reef ecosystems and fish populations. REEF’s database is an invaluable resource for marine scientists, and it is a privilege to help gather information that is useful for their work. I believe humans have a unique responsibility to care for the environment and our fellow creatures. Hopefully we can collectively make a difference in preserving these special living organisms and places for future generations.

What is your favorite fish?

My favorite fish are the butterflyfish because we almost always find them swimming in pairs. My husband and I have been married 46 years and we always snorkel together so the butterflyfish remind me of all the wonderful years we’ve had together. Surveying for REEF is one of the things we most enjoy doing as a couple because we are both biology teachers and love the ocean.

Where is your favorite place to dive and why?

We’ve lived in Wisconsin for the last 20 years, but I really love being near the sea. I’ve completed most of my surveys in the tropical Western Atlantic although I’ve also surveyed in Hawaii and the Galapagos. This summer I’ll be in French Polynesia for a week, and I’m looking forward to adding new fish to my life list. We were there almost 30 years ago, and that is where my husband and I fell in love with snorkeling although we didn’t know about REEF back then. It’s really hard to pick one favorite place, but I especially like the British Virgin Islands, the Bahamas, and Curacao because of the species diversity and beautiful water. Curacao probably tops my list because there are so many great places that are easily accessible from shore, and Playa Lagun is probably my favorite place to spend an afternoon there because I almost always see eels and interesting fish.

Do you have any surveying, fishwatching, or identification tips for REEF members?

Slow down and take time to enjoy really watching the fish—don’t be in a hurry to move on to a new spot too quickly. Linger in one place and try to figure out what the fish are doing. It’s not just about identifying and counting fish—it’s also about relaxing and savoring the privilege to be in this environment. If you slow down, you’ll use more of your senses, notice more details, and begin to feel that you are a part of the ecosystem even if only briefly as a guest. Absorb the tranquility and drift with the fish—breathe slowly, feel the water, and go with the flow. Always, always carry a camera because you never know what you’ll find.

Putting It To Work: Who's Using REEF Data, September 2016

REEF population data on Goliath Grouper are currently being used by several different researchers and government agencies to help support the recovery of this threatened species. Photo by Lureen Ferretti.

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:

- Data on three large Caribbean parrotfish species were provided to a scientist at California State San Luis Obispo to evaluate status and trends in these declining species.

- Data to evaluate population densities of herbivores in Bahamas and Belize were provided to researchers from Georgia State University.

- Goliath Grouper data were provided to researchers from University of Florida to build a spatial model to look at grouper management options and to the Gulf of Mexico Fishery Management Council to develop a Population Learning Model.

- Data on sea stars and sea urchins from the Pacific Northwest were provided to a researcher working with the Coastal Ocean Research Institute to report on the health of Howe Sound in British Columbia.

Field Methodology Course This Summer

REEF's Summer Field Course is a great way to get experience out on the water.

REEF Receives Exotics Funding from Mote’s Protect Our Reefs Fund

Dollars to Help Develop Rapid Response Plan 

In April of this year, REEF received notice our proposal to develop a Marine Exotic Species Action Plan was partially funded through the Mote Marine Protect Our Reefs Fund, which is funded through the Florida coral reef license plate. The project funding will go towards a SE Florida workshop with key federal, state and local agencies to develop a coordinated response plan for dealing with non-native marine fish. To date there have been more than 20 species of non-native fishes documented in a four-county area in Southeast Florida. Of these, the indo-pacific lionfish has become established in the US and Bahamas and is rapidly spreading throughout the Caribbean. To help address this issue and prevent other non-native fish invasions, coordinated early detection and notification, and rapid response plans are needed. 

REEF will be working in partnership with the USGS and NOAA to lead the early summer workshop focusing on drafting these coordinated action plans. Funding for outreach and to establish and train response teams later this summer is still being sought as part of this effort.

Stay tuned for an update on the workshop and for future plans for development of local response teams. Be sure to report any sightings of non-native marine organisms to the REEF exotic species website at www.reef.org/programs/exotic

Wellwood Monitoring Project Final Report Released

The M/V Wellwood, a 122-meter freighter, ran aground in 1984 on Molasses Reef off Key Largo, Florida. The grounding destroyed 1,285 square meters of living corals. The grounding transformed the area into a flattened, barren pavement covered with coral rubble. Eighteen years after the grounding, the area resembled nearby hard ground habitat with little structure and the benthic community was dominated by gorgonians. Natural recovery to a state similar to the pre-grounding condition failed to occur within a reasonable time frame and therefore, habitat restoration was initiated in May 2002. In the Fall of 2007, REEF completed a five-year monitoring project on the fish assemblages at the Wellwood grounding site and two nearby reference areas. A Summary Report, which summarizes the results of the monitoring effort, has been completed and is available for download from the REEF Wellwood Monitoring webpage.

Baseline surveys were conducted just prior to and immediately following restoration, quarterly monitoring took place through Year 1 and semi-annual monitoring in Years 2 through 5. The primary goals of this project were to aid in the assessment of restoration efforts and provide a benchmark for long-term evaluation of the fish communities at the grounding site. Teams of REEF Advanced Assessment Team divers conducted 558 roving fish surveys and 559 belt transect surveys during the five year monitoring project.

Report Conclusions:

After initial colonization, Restoration site fish assemblage diversity, density and biomass have leveled off and remain lower than that at nearby reference areas. A total of 165 fish species were recorded at the Restoration Site during the 5-year project. In comparison, 189 were documented at the North Reference site and 207 were documented at the South Reference Site. Parrotfish and surgeonfish appear to be responding quickest to the restoration efforts, with densities and biomass values similar to that of the reference sites. Grunt and snapper species are primarily absent from the Restoration Site. The relatively short duration of this study makes it difficult for results to be teased out from natural population variability. Similarly, definitive conclusions cannot be achieved from these data due to the limited amount of time that has passed since restoration and the well-known decadal processes that are required for coral reef development. However, these data will serve as a critical baseline for assessing future changes and the effect of any future restoration efforts at the site.

Notes from the Field – 2009 REEF Grouper Moon Project

The path of the current drifter that was released at the Cayman Brac aggregation site on the night of spawning (19 days at sea). The current pattern is similar to that seen with drifters released on Little Cayman. Jamaica is in the southeast corner.

Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort in the Cayman Islands aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species. The 2009 spawning season was the most ambitious to date for the project. For the first time, we had teams of researchers and volunteers stationed on each of the three Cayman Islands--Grand Cayman, Cayman Brac, and Little Cayman. The field season was certainly a success; among many interesting results and accomplishments, our most exciting find was that the teams on all three islands witnessed Nassau grouper spawning on the same night (Valentine’s Day, of all days! – which happened to be 5 nights after the full moon).

In 2003 the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all historically known aggregation sites in the Cayman Islands. 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 2009 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 Cayman Brac and Grand Cayman; aggregations on both of these islands were fished to exhaustion in the recent past. In addition to the island specific objectives, the Grouper Moon research program expanded satellite drifter work this season. These drifters, which track current patterns associated with the body of water the grouper eggs were spawned in, will continue to report positions for 45 days after spawning; this length of time is the approximate larval duration for Nassau grouper. REEF also continued education and outreach efforts through public talks about spawning aggregations and the Grouper Moon research. Talks were held at the Little Cayman National Trust and Dive Tech/Cobalt Coast Resort.

2009 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 Cayman Brac team’s goal was to document whether or not aggregating Nassau grouper were spawning-- evidence of spawning would refute the theory that Nassau grouper fail to recover once overfished because fish on small aggregations no longer release gametes. In the 2008 spawning season, the Grouper Moon research team discovered the location of an aggregation of Nassau grouper on Cayman Brac. This year, armed with this information, REEF and CIDOE researchers spent the full 2009 spawning season observing, videoing and documenting the Cayman Brac spawning aggregation. In addition, the team was able to accomplish the primary goal of this season’s work on the island—team members both observed and videoed spawning. Objectives for the Grand Cayman team were similar, except that they first had the task of discovering where Nassau grouper on that island go (if anywhere) during the spawning season. Using the acoutic tag pinger signal of just ONE Nassau grouper (of 6 total individuals tagged on Grand Cayman in 2008), divers confirmed the presence of aggregating grouper near the historic East End aggregation site and a dusk dive on February 14th yielded this season’s biggest accomplishment– team members witnessed Nassau grouper spawning on Grand Cayman!

The findings stemming from this work are unquestionably novel, and are certainly good news —protections on aggregation sites that have been fished to exhaustion will protect those few individuals that remain, and will protect stocks of fishes that are contributing to the next generation of this endangered reef fish. Put simply, our research demonstrates that overfished aggregations are down, but not out.

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, Chris Dixon, 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 2009 was no exception – heartfelt thanks to Judie Clee, Thor Dunmire, Tracey Griffin, Doug Harder, Brenda Hitt, Denise Mizell and Sheryl Shea. 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 students, Stephanie Kraft and Heather Reiff, 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 and Peter Hillenbrand, is also much appreciated. And finally, our ground-breaking achievements on Cayman Brac 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 Jules James.

Planning is underway for REEF's annual research on Nassau grouper spawning aggregations in the Cayman Islands for the 2010 spawning season - the Grouper Moon Project. This collaborative conservation program between REEF and the Cayman Islands Department of the Environment is entering its 8th year. Thanks to funding from the Lenfest Ocean Program of the Pew Charitable Trusts, the research team is conducting innovative research that is critical to the long-term survival of this iconic Caribbean species. Grouper Moon scientists will be in the field January 30 - February 12, 2010. If you are looking for a winter getaway and are considering the Cayman Islands, this is a great time to visit Little Cayman.

While there are not opportunities for recreational divers to visit the aggregation, researchers will be giving several public talks and divers on Bloody Bay Wall will witness the mass migrations of the normally solitary Nassau grouper from their home reefs out to the aggregation site. Another good reason -- the acclaimed Southern Cross Club has offered to donate a percentage of any package booked by REEF members during that time to support REEF's Grouper Moon Project.  To take a vacation and make a positive impact for the grouper, contact the Southern Cross Club reservation office directly at 1-800-899-2582 or info@SouthernCrossClub.com -- be sure to mention that you are a REEF member!

More information about the 2010 research and program objectives for the Grouper Moon Project will be included in future issues of REEF-in-Brief. you can also find out more about the Project on the Grouper Moon Project Webpage.
