Looking for a special gift for that certain someone. A 2009 REEF Trip makes a perfect gift. REEF Trips are not only fun, have diving and fish watching involved (which makes it perfect by my standards) but these trips are educational, green and are scheduled to some of the most beautiful Caribbean dive destinations. Also as an added bonus - all divers need a buddy so you get a good reason to give yourself a trip too!
REEF Trips are filling up fast. One trip that has been sold out for almost a year, Cozumel in December, just had a few spaces open up. This is your opportunity to join REEF Expert and Cozumel local, Sheryl Shea, on an excellent dive vacation. Sheryl is an a-fishy-a-nado extraordinaire and will be sure to infuse great fish watching, interesting local history and lots of fun on these trips. There are 3 spaces available during Week 1, December 6 – 14, including an opportunity for a double occupancy room – 1 male looking for a roommate and 1 female looking for a roommate. So if you are flying solo and don’t want to pay single occupancy we will put you in touch with a potential roommate. Please give us a call for more information and to reserve your space 305-852-0030. There are also a few spaces still available during the second trip, December 13 – 18. Please call the REEF Travel Desk for booking this trip – 877-295-7333.
So remember give the gift of Fish Watching for the holidays – we can prepare you a beautiful gift certificate and even arrange for it to be presented in an autographed fish ID book (or creature or coral) wrapped in Bottom Crawlers Holiday gift wrap. REEF Trips are a great way to enjoy yourself while making a valuable contribution to REEF on several different levels. Remember make this holiday season one that is All About The Fish!
Data collected as part of the REEF Volunteer Survey Project were the basis of a recent publication evaluating the effect of human population size on coral reef fish populations. The sweeping study, conducted by researcher Dr. Chris Stallings of Florida State University Coastal and Marine Laboratory, revealed that sharks, barracuda and other large predatory fishes disappear on Caribbean coral reefs as human populations rise, endangering the region’s marine food web and ultimately its reefs and fisheries. The study, which used data collected by REEF volunteers at sites in 22 Caribbean nations over 15 years, demonstrates the power of volunteer and community research efforts by non-scientists. Data are often insufficient at region-wide scales to assess the effects of extraction in coral reef ecosystems of developing nations. The REEF citizen science project fills this gap by generating valid and needed data over large geographic areas over long time periods.
While other scientists working in the Caribbean have observed the declines of large predators for decades, the comprehensive work by Dr. Stallings documents the ominous patterns in far more detail at a much greater geographic scale than any other research to date. The study found that nations with more people have reefs with far fewer large fish because as the number of people increases, so does demand for seafood. Stallings said that although several factors -- including loss of coral reef habitats -- contributed to the general patterns, careful examination of the data suggests overfishing as the most likely reason for the disappearance of large predatory fishes across the region. He pointed to the Nassau grouper as a prime example. Once abundant throughout the Caribbean, Nassau grouper have virtually disappeared from many Caribbean nearshore areas and are endangered throughout their range.
Dr. Stalling's article on the study, “Fishery-Independent Data Reveal Negative Effect of Human Population Density on Caribbean Predatory Fish Communities,” was published in the May 6, 2009 issue of the journal PLoS One. The paper is available for download here.

Over eight years ago, REEF expanded its flagship Fish Survey Project into Bermuda. Since then, local surveyors have contributed over 2500 surveys to the sighting database! In October, thirteen volunteers joined local REEF hosts Judie Clee and Chris Flook for a delightfully full schedule. After two extended survey dives each day, we were treated to a night snorkel and picnic to watch glowworms, a slideshow and dinner at the Bermuda Institute of Ocean Sciences, a private, guided tour of the nature preserve on Nonsuch Island, and a reception and presentations by the scientists from BREAM (Bermuda Reef Ecosystem Assessment and Mapping Programme). The week was topped off with a grand finale dinner and behind the scenes tour of the Bermuda Aquarium and Zoological Park.
One of the best things about fishwatching is seeing something new. Many areas have endemic fish and experienced fishwatchers know that fish coloration and behaviors can vary a lot from region to region. We arrived prepared to add Bermuda Bream, Bermuda Halfbeaks and Gwelly jacks to our lifelists but found ourselves equally thrilled to see the Bermuda version of the Yellowhead wrasse, called the Redback (for its distinctive red coloration) and the brilliant jewel colors of their Puddingwives. Between dives, Chris Flook, from the Bermuda Aquarium, filled buckets with rafts of Sargassum seaweed and pointed out juvenile chubs, crabs, shrimps, pipefish and frogfish. Judie’s expert eye helped us sort out the damselfish puzzle. We dived several times in an area where the Emerald Parrotfish was once quite common but has not been seen for many years. Our possible sightings have generated some excitement and Judie and Chris are investigating further. Our total species count for the week was 115 and included a rare sighting of a Conchfish.
Thanks go out to Triangle Diving for the welcome BBQ (and Lionfish hors d’oeuvres) and their excellent diving services. And very special thanks to the Bermuda Zoological Society for funding REEF in Bermuda and for underwriting many of our special activities of the week. We’ll be back – and promise that it won’t take eight years!
As this report reminds us -- REEF trips are more than just your average dive vacation. Be sure to check out the REEF trip 2010 schedule, which can be found online at www.REEF.org/fieldsurveys/schedule. We encourage you to join us on our adventures in 2010 and Take a Trip the Counts!
Members of REEF's Pacific Advanced Assessment Team (AAT) and other active surveyors gathered in central California earlier this month to survey fish and invertebrate life in the Monterey Bay National Marine Sanctuary (MBNMS). Twenty-two divers conducted over 140 REEF surveys at twelve sites during the week-long project. This was the 8th year that the coordinated expedition has been conducted, and the data collected serve as a valuable time-series of information on the status and trends of populations within the Sanctuary. The team was led by REEF Director of Science, Dr. Christy Pattengill-Semmens. Dr. Steve Lonhart, a lead scientist from the MBNMS, and Chad King from the MBNMS, also joined the group for the week to provide valuable local expertise.
In addition to this annual monitoring project, volunteers conduct REEF surveys year-round during their regular diving activities in the area. REEF surveys have been conducted in the Sanctuary since 1997, and to date, over 2,600 surveys have been submitted from the MBNMS in to the REEF database. Click here to see a current summary of REEF data from the MBNMS. The Sanctuary is home to many colorful fish and invertebrates and is a popular spot for sport diving. REEF data collected in the MBNMS are currently being analyzed to document changes in key rocky reef fish species. Projects like the annual MBNMS monitoring are a great way for active REEF volunteers to apply their skills and expertise. These projects are also just one more reason for REEF surveyors to improve their identification skills and increase their survey experience level.
A big thank you to the participating AAT members and other REEF volunteers, and to Dr. Steve Lonhart and Chad King for their participation and logistical support. We also greatly appreciate George Peterson and Justin Kantor from the Monterey Bay Aquarium for hosting our first evening seminar. Field support was provided by the Monterey Express; thanks to owner Tim Doreck and to Captain Phil Sammet for serving at the helm of our adventures. This project would not be possible without the financial support of an anonymous foundation.
Some of the best dive sites for fishwatching are in the least obvious places. The Blue Heron Bridge in Palm Beach, Florida, is one such biological hotspot. This is a top dive destination for sighting unusual species that can be added to your lifelist. Mike Phelan, REEF Expert surveyor, and two other REEF members, often dive this site. The day before Thanksgiving, they were treated to quite a sight – a large school of Cownose Rays! This is a rare sighting in Florida, but it’s just another day at the Blue Heron Bridge. Some of the more unusual and recent sightings include the Blackwing Searobin, Roughtail Ray, Northern Stargazer, Orangespotted Blenny, Polkadot Batfish, and the Chain Pipefish. The bridge traverses a small island located in the inland waterway near the Lake Worth inlet. The dive sites consist of a variety of eco-niches such as sand, shell rubble, sea grass, algae hydroid fields, sailboat mooring lines and anchors and of course bridge pilings and concrete rubble. The Blue Heron Bridge has over 282 species recorded in the REEF database and the number is increasing monthly (click here to see the full list).
The actual dive site is a local county park named Phil Foster Park that is protected with a no-take ordinance. All dives are shore-based and must be timed with the high tide. The dive can be safely done by entering the water one hour before high tide and exiting one hour after high tide. Depths range from 8 -17 feet and the water is usually clear even if the off-shore ocean is rough. Remember to bring a dive flag. Many divers combine their Blue Heron trip with some local Jupiter off-shore diving to witness the Goliath grouper aggregations in August or September, Loggerhead, Green, and Leatherback turtle nesting during the spring or the Lemon shark aggregation in the winter. This is certainly a dive site to be thankful for!

REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Jonathan Lavan (REEF member since 2004). Jonathan has conducted 195 REEF surveys in four REEF regions, and he is a member of the Advanced Assessment Team in the Tropical Western Atlantic. Here's what Jonathan had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
I got certified at age twenty in the cold waters of Maine. I dove there and in Florida for a number of years but then, like so many of us, life got in the way for several years. When I got back into diving I quickly realized that I really knew very little about what I was looking at. I started buying some ID books and eventually stumbled upon the Caribbean Fish ID Guide by Humann and DeLoach. Sometime after that I found the REEF website and saw that REEF had trips. My wife and I signed up for the Bahamas trip in ’04 with Paul Humann and after that I was hooked. I usually go on a couple REEF trips a year and any other trip I go on I always do REEF surveys whenever possible.
If you have been on a REEF Field Survey, where and what was your trip highlight?
Last April I went to Dominica with trip leader Heather George. On one dive I got a little separated from the group (as usual) as I was taking photos. I found a small cave and managed to hunker down to get a good look inside despite all my gear. Tucked way back in the cave I saw something quite small undulating like a piece of ribbon in the wind. It was a Black Brotula! Well I started shaking my rattle like crazy to try and get someone’s attention. Finally, Heather and another diver came over and after much gesturing and changing of places they both, finally saw it. I must say there was nothing more satisfying then when Heather looked around that last corner way back in the cave, saw the elusive fish and then I heard her say clearly through her regulator: “OOOooohh!”
What is your favorite fish or marine invertebrate?
I have many favorites but I have to say that I never get tired of watching or taking pictures of Secretary Blennies. They are so easy to personify with all their goofy expressions and fussy behavior.
Do you have any surveying, fishwatching, or identification tips for REEF members?
As a photographer and surveyor, the key (as many know) is to go as slowly as possible. Let the divemaster race on ahead or make it very clear to them that you are going to be going “SLOOOW”. Not looking under that last ledge could be the difference between a great dive and really great dive.
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!
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.
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).
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.
