REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.

Our outstanding Field Station this month is Aqua Safari in Cozumel. Aqua Safari has supported REEF since 2001. At that time, long-time REEF member and Cozumel local, Sheryl Shea, took the lead in promoting the Fish Survey program through teaching fish ID to both Aqua Safari staff and customers. That year, Aqua Safari hosted the first Cozumel Field Survey trip, with REEF surveyors and marine park staff submitting over 200 surveys in just a week! Today, REEF's database holds data for over 400 species and over 6,000 surveys from Cozumel. Aqua Safari currently offers several fish ID courses to the general public: A "dry" introduction to Fish ID for snorkelers and divers; the REEF Level 2 course; and Advanced Fishes. There are plans to add a course geared to the interests of underwater photographers and an in-water snorkeling course with surveying. The Level 3 and advanced-level surveyor exams are offered annually during REEF Week. The shop stocks REEF books -- including a reference set for its customers' use after diving -- and survey materials. And they continue to host an annual REEF Field Survey trip each December (see www.REEF.org/trips). Aqua Safari warmly welcomes REEF members whom, the staff says, are generally excellent and aware divers who never fail to educate others on their boats. Aqua Safari has been in operation since 1966, pioneering sport diving in Cozumel and serving the island as an advocate for conservation of its marine environment. During the 1990's, owner Bill Horn worked toward the establishment of Cozumel's marine park and has maintained his vigilance regarding park policies and use. Thank you, Aqua Safari!

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

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.

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:

-Fisheries scientist are using data on Hogfish from Florida, Puerto Rico, and the USVI to evaluate population status and help set effective catch limits as part of the US Fisheries Management Council's stock assessment.

- A scientist from RSMAS at the University of Miami is evaluating the status of Caribbean predatory fish species, including Gray Snapper, Barracuda, and Goliath Grouper.

- An environmental researcher at University of Miami is assessing biodiversity indexes as a measure of effectiveness with ongoing septic tank replacement and canal improvement projects in the Florida Keys.

- A PhD student from University of Hawaii is using data from Maui Nui to conduct coral reef ecosystem services models.

- A researcher from University of Victoria is using data from Washington and British Columbia to evaluate community richness values for temperate rocky reefs.

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!
