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).

More than sixty people gathered earlier this month at the Fish House Encore in Key Largo, Florida, for Lionfish Food and Wine Night. Before dining, event attendees learned about the lionfish invasion and the importance of removing lionfish from marine environments. Peter Tselikis, chef at Fish House Encore, showed the audience how to cook two popular lionfish dishes. Lad Akins, a renowned lionfish expert and REEF Director of Special Projects, taught the audience how to fillet lionfish, avoiding the venomous spines.

The invasive species, known for their voracious appetites and rapid reproduction, was prepared four different ways with a creative medley of ingredients and wine selections. Entrées included bacon-wrapped barbeque lionfish, sea salt-cured lionfish ceviche, and poached lionfish. Many guests said their favorite dish was Lionfish Bermuda, a lionfish fillet encrusted with fried red onions and Japanese breadcrumbs, baked and served with a sweet and sour sauce atop baby arugula salad.

“It’s exciting to see such strong public and commercial interest in consuming lionfish,” says Akins. “Developing a market for lionfish is a great way to provide incentive for increased removals. Even non-divers can make a real impact, by ordering the fish at their local restaurants, helping to decrease lionfish populations and minimize their impacts.”

Lionfish, native to the Indo-Pacific and Red Sea, have now invaded the Western Atlantic, Caribbean, and Gulf of Mexico. In the invaded range, they have been documented to be gluttonous predators of native fish and invertebrates. One published study co-authored by Akins (Green et al. 2012) shows lionfish reduced the native fish prey community at some sites in the Bahamas by an average of 65% in just two years. Some sites had a 95% decline. Despite the dismal outlook, there is good news. Published studies show local control by divers and fishers can be effective, Akins notes. “Removing lionfish from local reefs is like weeding a garden. Remove weeds and the garden is healthier. Remove lionfish and the reefs are healthier. The key is regular removals, year round.”

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 Juddith Cucco. Judith has been a REEF member since 2010, and has conducted 555 surveys (all in her home state of Hawaii, and all as a snorkeler!). She is a member of the Hawaii Advanced Assessment Team as an Expert Surveyor. Here's what Judith had to say about REEF:

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

I first heard about REEF through Reef Watch Waikiki while taking a fish identification course with them in February 2010. I immediately started doing surveys as I felt it was a fun way for me to share my enthusiasm for all the fish I see while snorkeling in Hawaii, where I live...and I wanted a record of the many species I've encountered.

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

Even though I've seen it many times, it still fascinates me to see cooperative hunting, for example jacks following a moray eel or blue goatfish. My favorite fish is the juvenile rockmover wrasse. They look like drifting seaweed in the ocean when they move and I enjoy watching them turn over rocks with their snout. My favorite discovery is a semi-circle angelfish (not native to Hawaii) that Christy Pattengill-Semmens (REEF Director of Science ) helped my swimming buddies and me identify from some very poor photos.

Where do you do most of your surveying?

I used to do most of my surveys at the outer reef in Hanauma Bay and still go there occasionally, however my favorite place to survey on Oahu is Kaiona Beach Park. You really need to look to find the fish and if one has the patience, there are ample rewards. I've seen so many species that one does not see at Hanauma Bay (knifefish, bigeyes and several types of scorpionfish). Because I snorkel, the fish are also much closer at Kaiona as it's more shallow.

What do you enjoy most about doing REEF surveys?

The most exciting thing for me when doing surveys is when I encounter a species I haven't seen before. After my snorkel, I go home and look it up in one of my fish books or online and enjoy learning about it. My biggest challenge is staying warm as I like to stay in the ocean until my fingers get numb (not recommended), which is usually around three hours even with a full wet suit.

Do you have a memorable story from a survey?

Just the other day, I had gone out for a snorkel survey (which ended up not happening). A little while into our swim, my buddy and I found an entangled green sea turtle. I saw it on the bottom in about ten feet of water. We first asked its permission, then dove down to bring it to the surface. We saw that it had fishing line wrapped around its neck and two front flippers. We were really far out on the reef and swam it in to shore. We recruited two fishermen to cut off the line and they also built a pen out of rocks for the turtle. I went to my car and called our local NOAA turtle stranding office. When NOAA staff arrived, we loaded the turtle in a carrier and the turtle was taken to a surgeon. It needs to have the front right flipper amputated, but it is going to survive and should eventually be released back in the wild. What an amazing and cooperative experience!!!!

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.
