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."
Patricia Richardson of Hawaii recently submitted her 1000th REEF survey! Pat joins 16 other REEF members in the Golden Hamlet Club. Pat has done most of her surveys at one location, Richardson Ocean Park in Hilo, which has given her a very unique perspective on how the populations change throughout the year and over time. When asked about her recent achievement and what she thinks about REEF, Pat had this to say-- "REEF has provided me with a purpose for my retirement years that is filled with constant beauty and new things to see and learn. I am very grateful to REEF for giving a focus to my passion. Imagine doing something so beatiful and satisfying - and getting to call myself a citizen scientist as a big bonus!"

This month we highlight Daryl Duda. Daryl has been a REEF member since 2012, and has conducted 43 surveys. He is working his way up the ranks, and is now a Level 3 Surveyor! Here's what Daryl had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I first learned about REEF during a stay in Key Largo while spending the day with the Coral Restoration Foundation. Later, I met Keri Kenning (past REEF intern and staff) at "Our World Underwater" scuba show in Chicago and she invited me to the little yellow house on my next visit to Key Largo. Its been over 2 years and I've been a member since.
What are some of your favorite moments as a REEF surveyor?
During REEF's 20th anniversary REEF Fest event last summer, I did my first survey dives, and it happened to be with Paul Human, Ned and Anna DeLoach, and Jonathan Lavan. After a morning full of interesting seminars, the afternoon diving with this all-star REEF cast made for an incredibly fun filled day. Since those first surveys, I find it difficult to be underwater and not identify and count fish. I feel like all my previous diving was just being underwater looking around. As the Sherpa said to Sir Edmund Hiliary as they scaled the mountain, "Some come to look, but others come 'To See'". I see things I have never seen before now that I started doing field surveys.
Do you have a favorite REEF Field Station?
There are many terrific dive shops in Key Largo. My favorite is Rainbow Reef Dive Center. They put a guide in the water with every 6 or so divers at no extra charge. This way I can concentrate on my photography and fish identification. Their crew is extremely knowledgeable about underwater life and curious about everything we see. Captain Alecia Adamson (another past REEF intern and staff) has become my fish ID mentor. Whenever I get stumped by a fish, I email her a photo and she helps me out.
Do you have a memorable fish encounter?
Diving on Molasses Reef in Key Largo one day, we swam around a ledge to see a 6 foot reef shark cozy up to a goliath grouper. The grouper let out a loud bellow that frightened the shark away. I never saw such a large fish swim so fast. Also, at Elbow Reef off Key Largo I got some good shots of a scrawled cowfish chomping on a jellyfish. It was the cutest thing to watch.
What is your favorite fish?
My favorite fish is the Porcupinefish. I can usually get reasonably close to get a good photo. They always look like they are smiling at you. I also like Honeycomb Cowfish that can change colors right before your eyes.
Any fishwatching tips to share?
I started of very slowly identifying fish because I didn't know very many. I always carry my camera on a dive and Ned DeLoach suggested using my point and shoot to help with my fish ID. Later back home I can zoom in and do a more accurate ID using my library of reference books. If I can't figure it out, I can email the photo to someone at REEF or post on the ID Forum at REEF.org.

Earlier this month, REEF Director of Science, Dr. Christy Pattengill-Semmens, participated in the first of a series of workshops to be held this Fall to analyze REEF and other data gathered from the Channel Islands Marine Protected Areas (MPAs). Originally established in 2003 (and then expanded to include Federal waters earlier this year), this network of no-take marine reserves protects 318 square miles around the northern five Channel Islands off the coast of California. In 2008, the California Fish and Game Commission will conduct a 5-year review of the MPAs to evaluate the effectiveness of the reserve network. The results from the evaluation will inform future decisions made by the Commission under California's Marine Life Protection Act. The data group workshops, held at the National Center for Ecological Analysis and Synthesis, will culminate in a series of publications summarizing the cumulative efforts of dozens of monitoring programs within the Channel Islands MPAs, with an emphasis on analyses that can best address key management questions concerning the reserves. These results will be presented during a special symposium associated with the California Islands Symposium.
Coincident with the establishment of the marine reserves in 2003, REEF initiated a coordinated monitoring program at specific sites inside and outside of the reserves to complement the ongoing survey activities in the area by REEF members. Surveyors on REEF's Pacific Advanced Assessment Team participate in annual REEF cruises aboard the Channel Islands National Marine Sanctuary (CINMS) vessel R/V Shearwater, and this project has generated over 800 surveys to date. These data, along with an additional 750 REEF surveys that had been conducted around the islands prior to 2003, will provide information on the fish assemblages (and more recently key invertebrate and algae species) of the Channel Islands.
To find out more about our work in the CINMS, visit the REEF in Sanctuaries page.
