Acoustic tagging is one of the most powerful marine conservation technologies currently available. REEF uses this technology in both the Grouper Moon Project and the Invasive Lionfish Program to help determine movement, ranges, behavior, and more. But tags and receivers are expensive! We need your help in furthering REEF's valuable marine conservation initiatives by supporting the purchase and implementation of these valuable tools. You can donate securely online at www.REEF.org/contribute. Read on to learn more about these high-tech tools.

What is an acoustic tag, hydrophone, and array? Acoustic tags are small electronic devices that, once secured to a fish, broadcast their identification by ultrasonic sound. Hydrophones that can detect these ultrasonic sounds are placed underwater via a buoy to record the presence or absence of fish. A group of hydrophones strategically placed in an area is called an array. Data from the array are periodically downloaded and analyzed to determine fish movement, residency, behavior, and more.

How do tagging studies make a difference for marine conservation?

  • Allows researchers to determine home ranges of fish to better inform management strategies including sizes and locations of protected areas
  • Documents behavioral activities, such as spawning or seasonal movement, to help researchers and managers better understand the biology and ecology of key species
  • Facilitates collaborative marine research through sharing of hydrophone data and array setups
  • Contributes to inspiring visualizations of fish movements for scientists, policymakers, and marine life enthusiasts

REEF's Grouper Moon Project has relied heavily on this technology to help answer questions necessary to hep conserve Nassau Grouper spawning aggregations. Populations of this iconic species have declined dramatically over the past half-century due to overfishing during winter months as they aggregate to reproduce. To find out more about this activity, REEF researchers and our partners at Cayman Islands Department of Environment set up an array of acoustic receivers and started tagging Nassau Grouper in 2005. Using data from this technology, REEF created a video that shows the remarkable migrations Nassau Grouper undertake during the spawning season. This visualization tool played a critical role in the creation of proposed legislation aimed at species conservation in the Cayman Islands. To watch this movie and read more about it, please click here.

Please make a donation at www.REEF.org/contribute so REEF can continue using acoustic tagging in projects and programs. This valuable tool helps ensure that we can protect iconic species like Nassau Grouper in the most effective manner. Thank you for your support.

Oceans of Thanks to Our Members

There are a few limited-edition 2015 prints left. Donors of $250 or more, received by April 4, will be sent this signed and numbered, limited edition print of a beautiful Fiji reef scene by Paul Humann.

I want to thank everyone who donated during our winter fundraising campaign. With member support, REEF was able to raise $115,000. Your contributions drive REEF programs, from protecting keystone species to educating the next generation of ocean enthusiasts. If you haven't donated yet, there are still a few limited-edition prints left for donations of $250 and over that are received by April 4th. You can donate online or call us at 305-852-0030.

This year’s campaign focused on our changing seas. Now, more than ever before, it is critical for REEF to monitor the effects from pressures on marine ecosystems. Pressures of great concern include overfishing on endangered species like Nassau Grouper, invasive species that threaten native ecosystems like Lionfish, and temperature changes that shift species habitat range like El Nino. Our dedicated surveyors have seen the changes over decades of underwater exploration. With your donations, REEF can ensure these changes are documented and distributed to researchers for the protection of marine species and habitats.

Thank you again for donating this season!

Grouper Moon Project Results in Sweeping Science-Based Protections For Nassau Grouper

We are excited and very proud to share amazing news – on August 15, 2016, the Cayman Islands government enacted a comprehensive set of regulations aimed at recovering Nassau Grouper, an endangered Caribbean reef fish. The new rules are based on more than a decade of collaborative fisheries research carried out by the Grouper Moon Project. REEF initiated the Grouper Moon Project in 2001 in collaboration with the Cayman Islands Department of Environment, and it has become one of our flagship programs. We work in partnership with scientists from Scripps Institution of Oceanography at UC San Diego and Oregon State University. The project is the Caribbean’s oldest continuous grouper spawning aggregation research program, and represents one of the most advanced, multi-faceted tropical fisheries research programs in the world.

The regulations represent the Caribbean’s most progressive set of management actions for Nassau Grouper, and include:

  • All take, possession, or sale of Nassau Grouper is prohibited from December through April (during the spawning months for the species)
  • When take is permitted (May – November), only fish between 16"-24” can be kept and no more than 5 Nassau Grouper per fishing vessel per day can be kept
  • Nassau Grouper may not be taken on spear gun at any time

Many of you have followed the progress of the Grouper Moon Project through the years. Our research has focused on the west-end aggregation site on Little Cayman, which supports one of the last great reproductive populations of this endangered species. Lessons learned in the Cayman Islands have benefited Nassau Grouper conservation efforts throughout the Caribbean.

The sweeping protections enacted for Nassau Grouper in the Cayman Islands last month represent the kind of action-oriented work that REEF is known for. This science-based management action would not have been possible without the dedication of Grouper Moon scientists and the support of REEF donors and volunteers. We greatly appreciate all our members who have contributed financially to REEF to make this important work possible.

We look forward to continuing our important work on spawning aggregations in the Cayman Islands and beyond. In addition to support from our members, REEF's work in the Grouper Moon Project has been supported by the Lenfest Ocean Program and Disney Conservation Fund. Significant field logistics support has been provided by Peter Hillenbrand, Southern Cross Club, and Little Cayman Beach Resort/Reef Divers.

We are proud to announce that on July 1st 2017, the number of REEF Volunteer Fish Survey Project surveys conducted by volunteers in the Tropical Western Atlantic (TWA) region topped 150,000! The 150k surveys have been conducted by 11,123 volunteers at 8,837 sites in the TWA region (which includes the Caribbean, Bahamas, and Gulf of Mexico). The first surveys in the TWA were conducted 24 years ago in Key Largo. Since then, REEF's citizen science program has grown to ocean waters world-wide and has generated the largest database on marine life population status and trends, recently surpassing 217,000 surveys! Visit our Top 10 Stats page to see the most frequently sighted species, the most species-rich locations, and our most active surveyors. We would like to say a huge thank you to all of our volunteers, supporters, and those who make use of these data! We couldn't have done it without you.

REEF's mission is to protect biodiversity and ocean life by actively engaging and inspiring the public through citizen science, education, and partnerships with the scientific community. The REEF Volunteer Fish Survey Project is a key component of our success. The program allows volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations in marine waters world-wide (and invertebrates and algae in temperate waters). Visit the About REEF page to find out more and to see where our volunteers are conducting surveys.

Okay, well not exactly. But now that I have your attention.  We ARE counting something in REEF HQ's backyard, not fish, but birds!  I have signed myself /REEF up for Cornell University's Lab of Ornithology Project FeederWatch, an annual survey of birds that visit bakcyard feeders in winter. I have known about this other great citizen science program for a couple of years and like many of you, my love for birds, equals my affinity for fishes.  Last week, 4 painted buntings visited REEF's feeder for a little over a week!  You can see my fuzzy picture of a couple of them at the feeder from afar in one of the attached photos. This prompted me to go online and investigate Cornell University's FeederWatch Program further.  From their homepage you will read, "FeederWatchers periodically count the highest numbers of each species they see at their feeders from November through early April. FeederWatch helps scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance."  Sounds a bit familiar doesn't it?  

Spend a little time on their website and you will see that FeederWatch parallels REEF programmatically in a few significant ways:  1. Anyone can participate in North America, all different levels from beginners to experts; 2. We both begin participation by purchasing a starter kit, FeederWatch calls theirs a Participant Kit and it costs $15; 3. Both organizations have online Dataentry and tracking of individual participant data; 4. Similar absence/presence data, abundances, and distribution for both groups in addition to viewing individuals' data http://watch.birds.cornell.edu/PFW/ExploreData; 5. Both of our organizations utilize citizen science data to inform and assist scientists in assessing population abundance indices of important avian and fish species, leading to peer-reviewed publications and ultimately influencing species and habitat management decistions; 6. You can check on their database to see what birds are rare in your area and if there are any other FeederWatch stations near you, just as REEF members can check for fish sighting frequencies and dive sites that have been surveyed in our areas of interest.

I'm sure there are many more parallels I could draw for you, but you get the point.  One important note and the reason I am submitting this article right now is that FeederWatch season runs from the the second Saturday in November through April and is a winter activity.  For all of our temperate REEF members who are looking for something to count when you're not underwater, this is it!  To learn more, check out their website at http://www.birds.cornell.edu/pfw/Overview/over_index.html.

Fishwatching - The Thrill of the Hunt For New Species

It's one of the great things about fishwatching and doing REEF surveys - no matter how many surveys you have conducted, there is always an opportunity to find something new. These "mystery fish" are what keep folks who have done even 1,000+ surveys coming back for more. Finding a "lifer", a species new to your species life list, is always rewarding. A great part of submitting REEF surveys is that REEF keeps track of your lifelist for you.  

One of the many data summary reports that are available through the REEF Website is your personal Life List Report, which includes all of the species that you have reported during REEF surveys. REEF Surveyors also have access to "My Survey Log", which lists information about each survey dive, including date, time, location and the number of species seen. In order to access these reports, you need to be logged into REEF.org. If you haven't already done so, create a Website login account today.

Active surveyors, Todd and Lynn Fulks, found one such "lifer" recently during a survey dive in San Blas, Panama -- a hogchoker (Trinectes maculatus). This little flatfish was happy to pose on Todd's slate underwater while they snapped a photo. Great find! Do you have your own great lifelist story? Please post it to the REEF Forum Discussion Board.  And if you are looking for a great read this Fall, check out The Big Year: A Tale of Man, Nature, and Fowl Obsession by Mark Obmascik. It chronicles obsessed bird watchers participating in a contest known as the North American Big Year, hoping to be the one to spot the most bird species during the course of the year. If you are a fish fanatic, you will definitely see some similarities!
