We have a full line-up of dive show appearances planned this year. If you are in the area of one of these shows, please stop by the REEF booth to find out what new and exciting things are happening. In 2013, we will be at: Our World Underwater (Chicago, February 15-17), Beneath the Sea (NJ/NY, March 22-23), Northwest Dive & Travel Expo (WA, April 20-21), and Northern California Dive & Travel Expo (Bay Area CA, May 11-12). We are always looking for volunteers to help at the booth. If you are interested in being a REEF ambassador, contact Martha at martha@REEF.org.
We are pleased to share the publication of two new scientific papers that utilize data collected by REEF volunteers in the Monterey Peninsula area of California. Co-authored by REEF Pacific Advanced Assessment Team (AAT) member, John Wolfe, and REEF Director of Science, Dr. Christy Pattengill-Semmens, the companion papers were published earlier this summer in the journal CalCOFI Reports. The first paper, Estimating Fish Populations From REEF Citizen Science Volunteer Diver Order-of-Magnitude Surveys, describes several mathematical models to convert order-of-magnitude count data (the type of data collected during REEF Roving Diver Technique surveys) to a numeric mean. The second paper, Fish Population Fluctuation Estimates Based on Fifteen Years of REEF Volunteer Diver Data For the Monterey Peninsula, California, used the best-performing model technique to evaluate population trends in rocky reef fish species along the Monterey Peninsula. Over 3,000 REEF surveys have been conducted in this region over the last 15 years. Many of these data were collected during an annual project within the Monterey Bay National Marine Sanctuary conducted with the help of members of the Pacific AAT. Changes in relative density over time were reported for 18 fish species, including several fisheries-targeted species. Strong concordance was also found between REEF data and those collected by Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), a consortium of academic institutions. Results showed that data collected by REEF have great potential to augment and strengthen professional research data and serve as a valuable baseline to evaluate marine reserves. Both of these papers can be found on the REEF Publications page here - www.REEF.org/db/publications (as well as downloadable from the CalCOFI Reports webpage).

This month we highlight Janet Eyre. Janet has been a REEF member since 2002, and has conducted 1,125 surveys. She is on the Advanced Assessment Team as an Expert Surveyor in four of REEF’s regions! Janet happily describes herself as a true fish nerd, and she has taken a lead role in assisting with REEF’s expansions to the tropical western Pacific. Here's what Janet had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
A letter from REEF in 2001 was my first exposure to the organization. The letter mentioned the Advanced Assessment Team (AAT) Expert Surveyor program and I remember thinking “wow, that would be cool to dive, count fish, AND do something good for the planet all at the same time.” So, on my next dive trips to the Caribbean in 2002 and 2003, with Reef Fish Identification: Florida, Caribbean, Bahamas in hand, I started doing REEF surveys. On my first REEF Field Survey Trip, to Belize in 2003, I tested into the Caribbean AAT. I also started doing surveys in Hawaii, and ended up as an Expert AAT surveyor there in 2004. I have conducted the majority of my surveys on the Kona Coast of the Big Island (Hawaii) where I am lucky to be able to dive with a group of like-minded friends and professionals at Jack’s Diving Locker. We all love diving deep as well as bobbing around in the surge zone in the search for as many species as possible on every dive.
Do you have a favorite REEF highlight or experience to share?
Even before REEF officially started the Survey Project in the South Pacific, I had been sending in the species lists from my Pacific trips. Now that the South Pacific is a “REEF Zone,” I have attained the top surveyor status in that region. The highlight of my REEF survey “career” came on the Field Survey Trip to Fiji in May 2013 when I counted 233 species on one dive! What a rush that was! It was also on that trip that I did my 1,000th REEF survey, so it was a double- milestone trip.
What inspires you to complete REEF surveys?
I come by my “fish nerdiness” honestly – my parents and grandparents were all birders. I never got into that, but once I started diving I was fascinated by identifying the fish, which I realize is basically underwater birding. I can (and do) spend hours just “reading” fish ID books.
Surveying for REEF is a passion for me because it satisfies me on several different fronts – (1) challenging me to find as many fish on a dive as I can, (2) giving me a reason and the means to learn to identify more fish, (3) doing something good for the planet, and (4) making each and every dive a new adventure (which gets harder and harder to do after 1,700 dives).
Do you have a favorite fish find or a fish quest?
One of my favorite fish is the Mandarinfish – its color pattern is just so incredible and gorgeous! I get a total charge out of seeing any “new-to-me” species but there are some fish I really would like to see – Psychedelic Frogfish, Gurnard Lionfish, Helfrich’s Dartfish, and Mola Mola (Sunfish) are at the top of that list.
To those who are in the know, St Vincent is considered the critter capital of the Caribbean. To those who watch fish, it is known that the rare is commonplace and that the fishwatching is unlike any other location in the Caribbean. REEF’s data from the June Field Survey supports those claims. With a team of 13 divers, the REEF group recorded an astounding 243 species, more than 65 of which were unlisted “write-ins” on the survey forms.
Diving with Bills Tewes at Dive St Vincent, long time REEF supporter and widely regarded “Caribbean Character”, the team split up on two boats and survey sites around the southwest end of the island. Long-time REEF expert Franklin Neal provided an extra special view from above and into shallow water as he snorkeled, while other team members spent hours on each dive exploring varied habitats and depths.
Special finds during the week would take an entire newsletter to list, but there were a few fish that stood out including the still undescribed Bluebar Jawfish on most sites, five frog fish on one dive, multiple black brotula, various pipefish commonly sighted and the largest spotfin gobies (10 inches?!) we’ve ever seen. The fish of the week may well have been the Golden Hamlet that Bill pointed out as his favorite fish and the species that adorns the cover of Reef Fish Identification.
The diving was bottom time unlimited and many dives exceeded two hours finishing in shallow water. Habitats were varied and visibility ranged from good to excellent on all of our dives. REEF is already planning our next Field Survey to dive St Vincent in August of 2008. The project will be led by Paul Humann and will be a must for any serious fishwatcher.

Here are a few notes and news bits we'd like you to know about:
On Saturday, February 9, REEF hosted the first annual For the Love of the Sea benefit dinner and auction at Amy Slate's Amoray Dive Resort in Key Largo, Florida. The event was a huge success! More than 150 guests attended a sold-out event, enjoying a picturesque sunset set to island music and the awe-inspriring underwater photography of authors and REEF founders, Paul Humann and Ned DeLoach. REEF raised more than $25,000 thanks to successful silent and live auctions and the generosity of event sponsors in the Keys and greater REEF community. Proceeds of the event will support ongoing citizen science projects to engage volunteers in marine conservation.
Many thanks to event sponsors for their support and to the local REEF "Fun Raisers" event planning committee. Please click here for more information on the event.
The recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the United States Geological Service (USGS), the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. As part of REEF’s Lionfish Research Program, over the last two years REEF has coordinated 12 research projects that have involved over 175 REEF volunteers. This research has generated a wealth of in-situ observations and over 1,000 lionfish specimens, which have led to great advances in the understanding of the biology and potential impacts of this most unwanted invader.
REEF’s most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement. Findings included:
Lionfish continue to grow in size: Tagging data show growth rates exceeding 190mm/year, far larger than necessary to reach sexual maturity.
Site Fidelity: All 12 previously-tagged specimens that have been recaptured indicate strong site fidelity even after 6 months.
Prey: Lionfish continue to amaze us during stomach content studies. The recent effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. Lionfishare eating nearly anything that will fit into their mouths.
Reproduction: Lionfish reproduction occurs throughout the year – many gravid females and a small recently settled juveniles have been found.
REEF’s future fieldwork will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program.

The USS Hoyt Vandenberg is the most recent ship to be placed as an artificial reef in the waters off Key West, Florida. The ship was sunk on May 27, 2009, but three weeks prior to the sinking the REEF team was in action conducting surveys of the sinking site and 7 other adjacent sites for comparison. The data will be used by the State of Florida to document fish recruitment onto the wreck and response of nearby reef sites to the new structure. In addition to regular REEF fish surveys, the team is also gathering important fish biomass data at two sites and recording any observations of non-native titan acorn barnacles, orange cup corals or non-native fish including lionfish.
The pre-deployment surveys at the sinking site did not document any fish present at the sandy bottom site though one barracuda was seen swimming through the area shortly after. Combined data from the 7 reference sites documented 159 species including rare sightings of pugjaw wormfish and cherubfish (rare for the Keys). The summary of data can be found here.
REEF will continue regular monitoring of the Vandenberg and reference sites through next summer, with a final report due by the end of 2010. A huge thank you to all of the REEF experts joining in on the effort including Rob McCall, Tracy Harris, Dave Grenda, Brenda Hitt, Jamie Giganti, Lisa Canty and Pat Zuloaga.
