Lad Akins, REEF Director of Special Projects, recently co-authored a paper summarizing work documenting feeding patterns of lionfish in the Bahamas. Understanding the predation behavior of this invasive species is important to be able to predict and mitigate the effects of Indo-Pacific lionfish (Pterois volitans) on Caribbean fish communities. Lad and his colleagues at Simon Frasier University studied the activity levels and prey consumption rates of lionfish on 12 shallow coral reefs in the Bahamas in relation to time of day and prey availability. Lionfish predation rates and activity levels were significantly higher during crepuscular (dawn and dusk) periods than at mid-day. Available prey fish biomass was highest at dawn but lower at mid-day and dusk, suggesting that lionfish predation activity is not limited by prey availability alone. The calculated average daily prey consumption rates was ~3 times the estimates obtained from studies of captive lionfish in their native range and of invasive lionfish observed only during the day. These results will help to predict more accurately the effect of predation by invasive lionfish on native reef fish communities. The study was published in the scientific journal Marine Ecology Progress Series, Vol. 433. A summary of this and all other scientific publications that have included REEF data and programs are given on the Publications Resources page, at http://www.reef.org/db/publications.

This month we highlight Rick Long. Rick joined REEF in 1997 and has conducted 469 surveys, making him one of Hawaii's top surveyors. Mike is a member of the Hawaii REEF Advanced Assessment Team and he lives on Maui. Here's what he had to say about REEF:
How did you first get involved with REEF?
I did my first REEF survey while diving in the Florida Keys and went inactive until I moved to Maui and joined the fish count at the Hawaiian Islands Humpback Whale National Marine Sanctuary. I learned the Hawaiian reef fish by participating in the monthly activities of a local REEF group called Fish Identification Network (FIN) and by volunteering at the Maui Ocean Center aquarium. I learned even more about fish behavior and corals by volunteering with the Herbivore project at Kahekili Beach, doing Reef Check surveys, and with Eyes of the Reef monitoring for coral bleaching and disease. Volunteering in all of these venues, I have learned not only the common names, but also some of the scientific and Hawaiian names of fish and other marine life. I am an enthusiastic advocate for Citizen Science.
In addition to surveying, what other ways are you involved with REEF?
Through the years, I have participated in monthly REEF survey shore dives organized by FIN and other groups. I have also taught Coral Reef slide shows at the NOAA whale sanctuary in Kihei that includes tips for visitors wanting to get in the ocean to see the beautiful fish and coral reefs in our state.
What is your favorite dive spot and favorite fish?
My friends are just as enthusiastic as I am, and can paddle outrigger canoes, scuba dive, or snorkel almost every day of the week in Maui. My favorite coral reef to survey is Maonakala, located within the marine protected area of the ʻĀhihi-Kīnaʻu Natural Area Reserve, and is one of the few coral reefs not in decline. One of my all time favorite fish is a special little chub or rudderfish that lives on this reef. The Hawaiians had a name for the Pacific Gray Chub (Kyphosus sandwicensis) in a yellow morph coloration and they called it the “Queen Nenue” (nay-new-ay).

REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
This month for our Field Station spotlight, we're heading up to the cold waters of Puget Sound - Tacoma, Washington to be exact. Here we'll find Bandito Dive Charters, whose boat, the Sampan, hosts about a 1,000 divers each year on sites in Puget Sound and the San Juan Islands. Bandito Dive Charters, owned by Captains Rick Myers and Jackie DeHaven, is lucky enough to have the critter ID talents of Jackie on board. Jackie is a REEF level 5 Expert surveyor for the Pacific coast region. She first got involved with REEF by taking a fish ID class from REEF Outreach Coordinator, Janna Nichols, over 9 years ago, and has done hundreds of surveys in the area. The dive charter has been a REEF Field Station almost 5 years now.
Jackie says, " Developing our flagship boat, Sampan as a REEF Field Station seemed a perfect fit to offer our customers REEF classes, materials, and the opportunity to talk about the diverse creatures found in our Pacific Northwest waters with a fellow diver (me, level 5 surveyor) who could assist with creature identification. We host several underwater photographers and the REEF field station status allows us to provide support for creature ID when the photographers are asking “What will I see?” at various sites."
Jackie continues, " We provide multiple copies of fish ID books focused on Pacific Northwest fish, invertebrates and nudibranchs. We provide slates, waterproof paper, and guided fish ID dives if requested and arranged in advance. We can teach REEF fish ID classes at our marina facilities prior to scheduled dive trips and/or on the boat en-route to dive sites." Bandito Charters would like to offer more intro-level REEF fish ID classes combined with two boat dives for the initial surveys.
Jackie's favorite fish – only because it's so rare for a diver to see – is the sixgill shark. She has been surveying Puget Sound waters since 2003 and has only seen them once or twice. In fact, in recent years, very few have been spotted at all in south Puget Sound. Jackie says, "Sixgill sharks are such large creatures who can move silently through your field of vision, almost elusive, yet they show such tremendous power, grace, and presence."
When we asked Jackie what things she liked best about REEF, she enthusiastically replied, "It is so EASY!!!! Submitting data online is quick, the Website is incredibly easy to navigate, and I feel that REEF surveys are offering a valuable tool for assessing the health of our waters and local species."
The ocean is a muse to many artists. REEF members have also felt that tug of creativity and sent us amazing pictures as well as commentaries from their travels. Being a part of REEF means sharing the underwater world that we all love which is why we'll be sharing with you the interesting pictures and experiences our members send us. We'd like to do this monthly, but need you to participate so email us your fun or interesting Fish Tales so we can publish them in the next REEF-in-Brief! Who knows . . . we may even choose your unique picture/story for placement in our annual news letter soon to be printed for 2008. Please email them to email@example.com titled ENews.
We also would like to share with our members a place to publish and read YOUR stories about ocean issues.
"Sea Stories, an online journal of creative writing and art about the world's oceans sponsored by Blue Ocean Institute, features contributions by ocean-lovers from all backgrounds and walks of life - writers, artists, educators, students, scientists, fishers, conservationists, explorers, and just regular people. Educators are invited to use Sea Stories in the classroom or as a publishing opportunity for yourself or your students. Join us in celebrating all things oceanic!"

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.
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.
