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 scientists from the Nature Conservancy in Washington is using REEF data to evaluate patterns of biodiversity in the Salish Sea and along the Oregon Coast as part of TNC's ecoregional analysis.
- A student at UNC Chapel Hill is using REEF data from the Galapagos Islands for use in a multimedia class project on data visualization.
- The Underwater Council of British Columbia requested REEF survey activity to be used in the BC Marine Conservation Analysis database being developed as part of the Marine Planning Partnership.
- A scientist from Florida Fish and Wildlife Conservation Commission is using data on Goliath Grouper populations in South Florida in the KeysMAP Marine Climate Change Adaptation Planning Project.
- Scientists from the Washington Department of Fish and Wildlife used data on lingcod, giant Pacific octopus, and other species to evaluate distribution and trends.
We are excited to share a new scientific paper published last month in the journal PLoS ONE that included REEF data - Global Population Trends and Human Use Patterns of Manta and Mobula Rays, by Christine Ward-Paige, Brendal Davis, and Boris Worm. Despite being the world’s largest rays and providing significant revenue through dive tourism, little is known about the population status, exploitation, and trade volume of mobulids (Manta and Mobula species). There is anecdotal evidence, however, that mobulid populations are declining, largely due to the recent emergence of a widespread trade for their gill rakers. Researchers from Dalhousie University and eShark.org used expert divers’ observations from two citizen science programs, REEF's Volunteer Fish Survey Project and eShark.org, to describe global manta and devil ray abundance trends and human use patterns. The study highlights the relative rarity of aggregation sites on a global scale and reveals that many populations appear to be declining. The authors warn that newly emerging fisheries for the rays gill-‐rakers likely exceed their ability to recover. The study also demonstrates the deficiency of official catch reports, as only four countries have ever reported landing manta or devil rays– Indonesia, Liberia, Spain, and Ecuador. However, numerous diver reports compiled in the paper illustrate that many other countries are regularly landing and selling these rays without reporting.

Here are a few notes and news bits we'd like you to know about:
Thanks to all who have made the beginning of our 2007 Field Survey year a successful start! There are still spaces available on two of our upcoming (see below). Keep an eye out for our 2008 Field Survey Schedule coming out soon in ENews!
WOODS HOLE (Sept 11-16, 2007) - Woods Hole and other New England sites – we have a few spaces left on this first-ever New England Field Survey led by myself, a self-proscribed New Englander. We will be diving Woods Hole, historic Plymouth of Mayflower fame, the historic fishing port of Gloucester, and Martha’s Vineyard. Our accommodations are in the village of Woods Hole that boasts 37 past Nobel laureates. The water temperature will be in the mid 70’s for all but two of our dives and we are sure to see some tropical fish mixed in with the temperate fishes. We will meet some of our New England counterparts in and out of the water. Please join us if you can.
BONAIRE (September 22-29, 2007) – There are 7 spots left on this unique trip led by Ned and Anna DeLoach. Bonaire is a wonderful place to learn your fish ID and benefit from two world experts in fish/invert ID and behavior. Bonaire deservedly boasts some of the best diving in the tropical western Atlantic and you’ll see many species on every dive with no worries about navigation while you gently dive out to the reef wall and turn left or right and follow the wall back. The shore diving is magnificent and you’ll want to take advantage of Ned and Anna’s underwater naturalist acumen and great conversations and stories. Eight of our top ten sites for species richness in the TWA database are from Bonaire. Hope to see you there!
To sign up for either one of these trips, contact Travel for You at 1-888-363-3345 or email firstname.lastname@example.org
On Friday, November 30, REEF welcomed more than 100 local members and new friends to REEF HQ in Key Largo, Florida for the first annual Holiday Open House. The event was intended to raise awareness about REEF in the community and educate REEF neighbors about critical conservation projects going on in the Florida Keys. The first in a series of signed, limited edition Paul Humann prints was raffled off, authors and photographers Ned and Anna DeLoach signed books and everyone enjoyed celebrating the season with friends and fellow fish watchers.
If you find yourself in the Florida Keys, we hope you will swing by and say hello at 98300 Overseas Highway, Key Largo. Many thanks to the newly formed Key Largo Fun-raisers group for helping with this event: Amy Slate, Evelyn McGlone, Mary Powell, Amy Fowler, and Sharon Hauk.
Hello and Happy April!
In this edition of REEF-in-Brief, learn about exciting work happening in the Turks and Caicos islands, new lionfish information and opportunities and the chance to help REEF collect data in the tropical eastern Pacific. REEF members recently helped the Northwest Straits Commission locate and remove a derelict fishing net in Hood Sound, Washington, while staff and volunteers made a splash at a south Florida Earth Day event. Please mark your calendars for the 17th Great Annual Fish Count (GAFC), taking place throughout the month of July. The GAFC is a great opportunity for fish watchers new and old to contribute to the largest marine life data collection event REEF holds all year.
My bittersweet news is that this is my last week at REEF. I will be staying in the marine conservation community here in the Florida Keys and will continue to support the critical work that REEF does. The Board of Trustees has identified a strong candidate for my replacement, details of which you will be provided soon. I sincerely appreciate the support each of you has shown REEF and hope our paths cross in the future. Until then, best wishes and best fishes,
Earlier this week, on March 3rd, 2009, the number of REEF surveys conducted by volunteers in the Tropical Western Atlantic (TWA) region (incl. the US East Coast, Caribbean, Bahamas, Gulf of Mexico) topped 100,000! The REEF Volunteer Survey Project database as a whole (including all regions) reached this benchmark in October 2006. The 100k surveys have been conducted by 8,582 volunteers at 6,203 sites in the TWA region. Other remarkable project milestones reached this week -- there are now two TWA surveyors who have conducted over 2,000 surveys each(!), many of our surveyors in the Pacific and Hawaii regions are about to surpass the 500 survey mark, and the number of surveys conducted in the Pacific region will soon exceed 15,000. Visit our Top 10 Stats page to see the most frequently sighted species, the most species-rich locations and our most active surveyors.
REEF's mission, to educate and enlist divers in the conservation of marine habitats, is accomplished primarily through the Volunteer Survey Project. The program allows volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations from throughout the coastal areas of North and Central America, the Caribbean and Hawaii, as well as on selected invertebrate and algae species along the West Coast of the US and Canada. The data are collected using a fun and easy standardized method, and are housed in a publicly-accessible database on REEF's Website. These data are used by a variety of resource agencies and researchers. To find out more about who is using the data, visit the Publications page on the REEF website. The first surveys were conducted in 1993. As of February 2009, 125,717 surveys have been submitted to the REEF Survey Project database. Visit the About REEF page to find out more and to see where our volunteers are conducting surveys.
Just when you thought you had it all figured out, you realize there is more to learn. A few years ago, scientists working on Blue Rockfish genetics discovered that there were actually two species of Blues. After fishermen bagged both types off Eureka, California, and were able to correctly separate them by appearance, Drs. Tom Laidig and Milton Love wondered if they could be correctly identified by divers underwater, and in what range and depth they are found. What a perfect project for our west coast REEF surveyors.
Using photos taken by Pacific NW AAT members (Pete Naylor, Janna Nichols) in both Monterey and the Neah Bay area (on our annual REEF survey projects of these areas), they were able to determine that yes indeed, the two species of Blue Rockfish could be correctly ID’d underwater. Both species are being found along the California, Oregon and Washington coasts by fishermen. REEF surveyor Taylor Frierson has seen both species (in the same school!) while diving near Newport, Oregon. The Oregon Coast Aquarium has both species of Blue Rockfish on display in Halibut Flats – a good way to compare them.
Although the species has yet to be officially described, REEF is asking Pacific surveyors, whenever possible, to start separating the two into what for now will be called, “Blue Blotched” and “Blue Sided”. These new species are listed in the Unlisted Species section on the online data entry form. A general “Blue Rockfish” category will still exist if you’re unsure (the one listed on the Listed Species list). We are also asking surveyors who have photos from previous survey dives, to go through and if they can positively ID the species seen based on the photos, to submit the change to us at email@example.com. Please include the survey number (if know), date, and location.
To help you ID the two species, here are some tips:
