Putting It to Work: Who's Using REEF Data, March 2012

Photo by Janna Nichols.

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 Florida International University is using REEF data from the Florida Keys to study changes in trophic interactions as a result of changes in top level predator communities in no-take reserves.

-REEF is working with staff from the Pew Environment Group and Southeast NOAA Fisheries to provide data that will facilitate the evaluation of Warsaw Grouper and Speckled Hind populations in the South Atlantic Ocean.

Release of Invasive Lionfish: A Guide to Control and Management

REEF is excited to announce the release of Invasive Lionfish: A Guide to Control and Management. Available as an e-book to view and/or download (formatted for desktop and mobile devices), this extensive manual was created to aid coastal managers and field workers in effectively managing the invasive lionfish problem. This best practices manual consists of chapters on control strategies, outreach and education plans, research, monitoring, legal considerations, and ideas for acquiring resources and vital partnerships from around the region. Invasive lionfish are a major ecological disaster causing wide-reaching negative impacts throughout the western Atlantic, Caribbean and Gulf of Mexico. By utilizing examples provided in this guide, researchers and managers throughout the region will be well equipped to address the lionfish invasion.

This work would not have been possible without the collaborative efforts of NOAA, REEF, ICRI, the United Nations Environment Programme, Caribbean Environment Programme, SPAWRAC, and the 40+ participants of the 2010 Caribbean Regional Lionfish Workshop. This manual will be the first book in the new GCFI Special Publication Series. Authors include James Morris (NOAA), Dayne Buddo (University of the West Indies, Jamaica), Stephanie Green (Simon Frasier University), Ricardo Lozano (CONANP, Mexico), and Lad Akins (REEF).

2013 Summer Lionfish Derby Series Announced

We are excited to announce the 2013 Summer Lionfish Derby Series! Five years ago, REEF began hosting lionfish derbies throughout Florida and the Caribbean to address the lionfish invasion. A lionfish derby is a single day team competition to collect as many lionfish as possible. Teams collect lionfish using nets or spears while SCUBA diving or free diving, and prizes are awarded to the teams with the most lionfish, biggest lionfish, and smallest lionfish caught. Not only do these events reduce lionfish populations, but they also increase education and awareness, provide samples for research, train divers in safe removal techniques, and help develop the market for lionfish as a food fish. To register or learn more, please visit www.REEF.org/lionfish/derbies. 2013 Derby dates and locations are: June 22 - Green Turtle Cay Bahamas; July 27 - Fort Lauderdale, FL; August 17 - Palm Beach, FL; September 14 - Key Largo, FL.

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 Herb Gruenhagen. Herb has been a REEF member since 2001, and has conducted 208 surveys (all in his home state of California). He is a member of the Pacific Coast Advanced Assessment Team as an Expert Surveyor. Here's what Herb had to say about REEF:

When and how did you first volunteer with REEF or become a REEF member?

In July 2000, the San Diego Ocean Foundation sunk a Canadian Destroyer as an artificial reef. I was one of several divers who performed both fish and invertebrate surveys, using transects, quadrats, and REEF Roving Surveys. When the San Diego Oceans Foundation decided to become a REEF Field Station, I volunteered to become a volunteer REEF instructor. I have been teaching a REEF class each month in San Diego since that time.

What are some of the highlights of your local diving?

I dive the La Jolla Shores most of the time, and it is always changing. There are the resident species, the transients, and the seasonal ones. The resident species will always be there no matter what. The transients can be the many pelagic species that the currents bring in. For example, a while back, we are seeing several different species of jellyfish and the leopard sharks are returning to the warmer water shallows near the Marine Room. The seasonal species are really the special surprises. During the early spring the nudibranchs come out to start their mating, and in the winter, we have a ‘white’ Christmas with all the Market squid schooling, mating, and laying their white finger-like egg cases. Other special surprises can be molas, baby grey whales, midshipman, mantis shrimp, wolf-fishes, and even Finescale Triggerfishes.

What is the most interesting thing you’ve learned doing a REEF fish survey?

Doing REEF surveys really highlights the many different variations that a given species can take on. Being a REEF surveyor gives you the ability to recognize new species from common species, and all the many variations within the same species. Paying attention to all the details is really important to getting a good ID. I try to get a good image of the fish and ask for help when I’m not sure.

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

After all the years of teaching the courses, I’m just really glad to see local divers coming to my class to expand their knowledge of the local marine life, whether they do one survey or many surveys. I love watching the learning process and expanding the students minds of the many wonderful forms of marine life we have here to enjoy and need to perserve for future generations.

Do you have a favorite local (or not) REEF field station or dive shop?

The REEF Field station is the San Diego Oceans Foundation, but the facilities that we use is Ocean Enterprises in San Diego. Ocean Enterprises has been very supportive over the years and everyone really appreciates the use of their classrooms, computer and projector and its central location in the city. Thank you Ocean Enterprises for your many years of support.

What is the most fascinating fish encounter you’ve experienced? What is your favorite?

Well, of course photographing species new to science or that is rare or very uncommon is a highlight. I have photographed several fishes and nudibranchs that fall into one of those categories. My most fascinating fish that I have seen is the Specklefin Midshipman, Porichthys myriaste. We see many juvenile Plainfin Midshipman in the winter, but the Specklefin were quite a find! One of my favorite fishes is the Sarcastic Fringehead. They are one of the few fishes that see you as a threat and will interact with divers and their photo gear. They will charge out of their breeding holes (ok, we are talking about a 6” fish) at the camera lens, thinking they are seeing ‘another’ fringehead in the lens. They will bite all your cables and your finger and charge back into their hole. They will also interact with each other and fearlessly defend their breeding holes by opening their mouths at each other beyond the stretching point.

Herb teaches free Southern California Marine Life ID classes the third Wednesday of each month. Join him!

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 Roger Skillman. Roger has been a REEF member since 2009, and has conducted 45 surveys. Despite being landlocked in the Smoky Mountains, he is an active surveyor in the Carolinas and Florida. He also teaches SCUBA and incorporates REEF in to his classes! Here's what Roger had to say about REEF:

What’s your favorite part of REEF surveying?

I like completing REEF surveys to document what was seen on any given day at a particular dive site. Completing surveys helps establish baseline data for a site. REEF members are “Citizen Scientists” with their eyes in the water and we provide valuable data for researchers that can’t be everywhere. The most interesting thing I have found about completing surveys is the importance of an underwater camera and a variety of good fish ID books to help with identification after the dive.

Do you have a favorite place to do surveys?

I have two favorite places that I like to dive. Most of my 34 years of diving have been on the shipwrecks offshore of Beaufort, North Carolina. The historical shipwrecks and abundant marine life that can be found rivals diving anywhere around the world! During the last 5 years, I have discovered the great diving around Jupiter, Florida, to include the world famous Blue Heron Bridge. BHB, with its unusual creatures and the ledges offshore, provide as many different species of fish as many tropical locales.

What is your favorite fish find?

My most fascinating fish encounter has to be diving with the Sand Tiger Sharks on the shipwreck “Caribsea” offshore Cape Lookout, NC. Diving while surrounded by 50 of these magnificent creatures was a marvelous experience. A most memorable fish find occurred at Blue Heron Bridge in 2013. I was completing open water evaluations with two of my students when we found not one, but two, Striated Frogfish. I had never seen a frogfish and these “neophyte” divers saw TWO on their first ever open water dives! Sometimes life just doesn’t seem fair!

What advice do you have for other REEF members?

The best way to benefit from REEF is to get INVOLVED! I belong to inland-based REEF Field Station (Smoky Mountain Divers-Carolinas) but that doesn’t stop us from conducting surveys. Contact our field station or a field station near you and participate in their fish ID programs. Sign up and participate in the numerous webinars and classes offered by REEF to expand your knowledge. It’s not hard, just FUN!

Be On The Lookout - Indo-Pacific Damsel Reported in Gulf of Mexico

We are encouraging all REEF surveyors in the Tropical Western Atlantic region to be on the lookout for a new non-native fish! Researchers from the University of Veracruz have documented a new non-native species in the southwestern Gulf of Mexico with the potential to spread throughout the region. Sightings of the Regal Demoiselle (Neopomacentrus cyanamos) have recently come from the nearshore reef systems south of Veracruz, Mexico. The species is native to a broad region of the Indo-Pacific and Red Sea. The damselfish was documented at depths from 2-21 meters, though it was more common on deeper reefs. Similar in appearance to the native Brown Chromis, the Regal Damsel can reach sizes of up to 9 cm (3.5 inches) in length and is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the tail, dorsal and anal fins. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin. Observations from Dr. Ross Robertson indicate the Regal Demoiselle can be a bit more cryptic than the native Chromis, tending to hide under ledges and in crevices between corals, rather than swimming in the open. Experts in Mexico believe that this damsel has the potential to disrupt natural systems around Caribbean reefs, as they have witnessed displacement of the native Brown Chromis on heavily-invaded sites.

If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.

Putting It To Work: REEF Data Used to Evaluate Species in the Northeast US

We are proud to share a story from the East Coast that is a perfect example of how REEF data are put to work to address our changing seas. Dr. Peter Auster of the University of Connecticut and Mystic Aquarium, recently submitted a petition to add the Radiated Shanny and Atlantic Seasnail to the list of Species of Concern under the State of Connecticut's Endangered Species Act. Dr. Auster used REEF data as his primary source of information for the petition.

Both species are considered "cold-adapted," with their distribution largely north of Cape Cod with rare sightings in Long Island Sound. Data show that these species may be the first climate-change casualties in Connecticut waters as Long Island Sound continues to warm. These species occur in rocky habitats, and the best population data come from diver surveys, such as those from the REEF Volunteer Fish Survey Project. If you are a REEF surveyor in the northeast region, please keep an eye out and report these species on your surveys! Dr. Auster will continue to track their abundance through the REEF database and assess the effect of changing seas on their populations.

Putting It To Work: New Study Documents Transboundary Impacts of Sea Star Wasting Disease

Sea star wasting disease has devastated sea star populations on the West coast from Mexico to Alaska. The disease broke out in 2013, causing massive death of several species of sea stars. Infected animals develop lesions that eat away tissue, with limbs dropping off as the animals die. The disease has been linked to a virus, although environmental factors may also be involved.

A new study, published last week in the scientific journal, PLoS ONE, presents an analysis of REEF survey data on several asteroid species collected by divers in the Salish Sea over the last 10 years. The Salish Sea is a Canadian / United States transboundary marine ecosystem, and world-wide hotspot for temperate asteroid species diversity with a high degree of endemism.

The results showed that some species were hit hard, while others increased in number. Populations of Sunflower Sea Star (Pycnopodia helianthoides), an important keystone predator in the region, dropped dramatically after the beginning of the epidemic. Several other sea star species, including the Spiny Pink Star (Pisaster brevispinus) also declined. Numbers of the less-common Leather Star (Dermasterias imbricata) and two species of sea urchin, which are prey for sea stars, increased after 2013.

The virus outbreak continues, and will have lasting effects on the ecosystem. Sunflower Sea Stars have effectively disappeared from the Salish Sea, the study concludes. Likely as a result, numbers of urchins have increased, which in turn will lead to more browsing on kelp. As a result, study co-author, Dr. Joe Gaydos, and his colleagues are currently in discussions with the National Marine Fisheries Service to get the Sunflower Sea Star listed as a “species of concern.”

The paper, titled "Devastating Transboundary Impacts of Sea Star Wasting Disease on Subtidal Asteroids", is available online here. Another study published earlier this year in the journal, PeerJ, used the REEF data to evaluate the potential trophic impacts of the seastar decline, as seen in the increase in sea urchins. That paper is availble here. View the entire list of all scientific publications that have included REEF data and projects at www.REEF.org/db/publications.
