REEF Welcomes New General Manager


When you call the REEF office, you may be greeted with a new voice. Please join us in welcoming Martha Klitzkie as the new General Manager. After completing a Bachelor of Arts from Warren Wilson College, a passion for marine education led her to serve as the Education Director at the Pigeon Key Foundation in Marathon, Florida. She later went on to direct a larger marine education program based at Camp Ocean Pines, located on the central coast of California. During this time she also completed a Master of Arts in Educational Leadership and Administration from Argosy University. But a love for the Florida Keys and its coral reefs brought her back home to the sunshine state to join the REEF team. As the General Manager, Martha supervises a variety of activities necessary to the day-to-day operations at REEF. Welcome, Martha!

Putting it to Work: Study Documents Decline in Bahamian Fish Populations Due to Lionfish Predation

REEF data showing increase of lionfish in New Providence, Bahamas, between 2004 and 2010.

There is growing concern that lionfish will affect the structure and function of invaded marine ecosystems. REEF Director of Special Projects, Lad Akins, is a co-author on a recently published paper evaluating these effects. The study was published in the scientific journal, PLoS ONE. Lead author, Stephanie Green, from Simon Fraser University (SFU), along with Akins and other co-authors Aleks Maljković (SFU), and Isabelle Côté (SFU), documented a dramatic 65% decline in 42 species of reef fish eaten by lionfish over a two year period. The study, conducted off New Providence Island in the Bahamas, used data collected during REEF's volunteer lionfish projects to track the explosion of the lionfish population over time, and reveals that lionfish biomass increased from 23% to nearly 40% of the predator biomass on the study sites between 2008 and 2010. This study represents the first documented direct impact of lionfish predation on native reef fishes and highlights the importance of control programs to minimize impacts. You can find a link to this and all published papers that have included REEF data on our Publications page.

New research using powerful genetic techniques and the REEF survey data have revealed two new species of hamlet in the Caribbean. The findings were recently published by scientist Ben Victor in the Journal of the Ocean Science Foundation. As our Caribbean surveyors know, hamlets are a group of colorful small sea basses that can sometimes cause ID confusion because of their myriad of colors and patterns. The varied color patterns in these small predators are thought to be a result of mimicry of other colorful but more innocuous herbivore species. There has been ongoing debate about which are actual species and which are simply just color variants or morphotypes. Ben's research revealed significant genetic differences among what seemed to simply be variations of the well-known Barred Hamlet. Ben stated that "the REEF database supplied valuable survey data indispensable to understanding ranges and abundances and unmatched in its comprehensive coverage".

The two new species are the Florida Barred Hamlet, Hypoplectrus floridae, and the Contoy Hamlet, H. ecosur. The typical Barred Hamlet (H. puella) that is found throughout the Caribbean will be updated in the REEF database to be called the Caribbean Barred Hamlet. Florida Barred Hamlet have been found in the eastern Gulf of Mexico and South Florida, and overlaps in range with the Caribbean Barred Hamlet in those areas. To date, the Contoy Hamlet has only been documented on Isla Contoy near the northern tip of the Yucatan peninsula and maybe Isla Mujeres. Florida Barred Hamlet are distinguished by a pair of symmetrical dark spots at the base of the caudal fin along with a break in the mid-body narrow bar. The Contoy Hamlet is distinguished by the same paid of dark spots at the base of the tail as well as a series of additional dark spots along the upper caudal peduncle and below the dorsal fin. A PDF of Ben's paper can be found online here, and it includes many pictures of the new species. Video of the Contoy Hamlet has been posted on Youtube.

REEF surveyors in the regions of the new species are encouraged to learn the differences and being reporting them as distinct species using the Unlisted Species section of the online data form.

The Faces of REEF: Joe Gaydos

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 Joe Gaydos, Ph.D., an avid REEF volunteer in Washington State and Director of the SeaDoc Society (a REEF Field Station). Joe has been a REEF member since 2003 and has conducted 120 surveys. He is a member of the PAC Advanced Assessment Team, and Joe was instrumental in initiating the AAT San Juan Islands Annual REEF Monitoring Project that kicked off this summer (see story in this enews issue). Here's what Joe had to say about REEF:

How are you involved as a REEF member?

I conducted my first REEF survey in Washington State in 2003, and have been doing them ever since. In addition, the program I run, the SeaDoc Society, is a REEF Field Station. We’ve hosted numerous fish and invertebrate identification classes and multiple Great Annual Fish Count dives, but I’m most excited about our new monitoring program collaboration. We’ve partnered with REEF to have Advanced Assessment Team Divers come to the San Juan Islands for annual week-long survey trips. We expect that over the next 8-10 years these data will help us understand long-term sub-tidal changes in the ecosystem.

What inspires you to complete REEF surveys? What is the most interesting thing you’ve learned doing a REEF fish survey?

I live and dive in the Salish Sea, a 17,000 square kilometer inland sea shared by Washington and British Columbia. The data collected by REEF volunteers are valuable to the managers in the region who are working to recovery declining species like Northern Abalone and Rockfish. I love being able to collect data that is meaningful.

In your opinion, what is the most important aspect of REEF’s projects and programs?

As a scientist, I love that the REEF data are collected in a way that is scientifically rigorous. Volunteers are trained and their level reflects their training and experience. Also, it is great that the data are collected and stored in a way that they will always be available for evaluation – even decades from now. This is citizen-science at its finest.

Where is your favorite place to dive?

My favorite place to dive is about 2 miles from my house. It’s a high current area split by an island so you get the benefits of seeing all of the invertebrates that flourish in the current, but you can always dive on one side of the island or the other. The site is familiar, but strikingly beautiful and I always find something new. The water is cold here and people generally expect everything to be dull and they are amazed to see videos or stills of colorful invertebrates and fishes.

Is there a fish (or marine invertebrate) you haven’t seen yet diving, but would like to?

Here, most everybody wants to see a Giant Pacific Octopus – 150 lbs, 2,240 suckers (unless it’s a male, then they only have 2,060) – what’s not to love. But me, I still want to see a Pacific Spiny Lumpsucker. They’re only the size of a golf ball, but dang are they cute. When is Disney going to make a movie starring one of them?! Maybe this year.

New Invertebrate and Algae Survey Program for the Northeast!

REEF is excited to announce that we have added a new invertebrate and algae survey program to the Northeast region (Virginia - Newfoundland). Similar to our other temperate regions, REEF surveyors in this area can now record all fishes as well as a select group of 60 invertebrate and algae species. Species included in the program were selected in consultation with regional scientists and experts to serve as a representative sample of the biodiversity of the region. Consideration was given to species that are habitat indicators, are harvested, and those that are just fun to look at (like nudibranchs!). REEF Outreach Coordinator, Janna Nichols, launched the new program at the Boston Sea Rovers meeting last month. As part of the new program, we have created a new underwater survey paper that includes the invertebrates and algae, as well as a waterproof color ID card. New training curricula are currently being developed for Northeast Fishes and Northeast Invertebrates and Algae. All of the new materials can be found on the REEF online store. A big thanks to all who helped shaped this program, provided guidance, and donated images for the new materials.

Putting It To Work: Who's Using REEF Data, March 2015

Identifying YOY rockfish habitat is one recent use of REEF data. Photo by Janna Nichols.

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:

- Scientists from NOAA Northwest Fisheries Science Center are using REEF data on juvenile (YOY, young-of-year) rockfishes to evaluate potential YOY habitat for development of a monitoring program in the Puget Sound.

- A scientist from Florida Fish and Wildlife Conservation Commission (FWCC) is using REEF data to evaluate the spread of invasive lionfish in the Gulf of Mexico.

- Another scientist from Florida FWCC is using REEF data to evaluate populations of Goliath Grouper in Florida and the Gulf of Mexico as part of the species' protected status review.

- Graduate students from Coastal Carolina University are assessing biodiversity, status, and trends of fishes and invertebrates in the South Atlantic States (SAS) region (the Carolinas and Georgia).

Details on these trips are below, and the full schedule of REEF Trips can be found at REEF Field Survey trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their lifelist while interacting with fellow ocean enthusiasts. Book early - REEF trips often sell out! Also, keep an eye on the REEF Trips webpage and your inbox- we'll be announcing the full 2017 schedule soon.

Micronesia by Land and by Sea - Manta Ray Bay Resort in Yap and Palau Aggressor II Liveaboard, October 4 - 16, 2016. REEF members and enthusiastic fish surveyors will not want to miss our first-ever Field Survey Trip to Micronesia, alongside REEF's Director of Science, Christy Pattengill-Semmens! This exciting 12-day adventure begins land-based at the world-renowned Manta Ray Bay Resort in Yap, featuring three days of diving Yap's rich coral walls, channels, and lagoon sites, all while observing creatures including manta rays, reef sharks, and maybe even mating mandarinfish. After diving Yap, recharge with a night at the Palau Royal Resort, within walking distance of the yacht marina. Then the excursion continues with a 7-night charter aboard the Palau Aggressor II, with the opportunity for up to 5 dives per day in warm, tropical water. Surveyors can look forward to discovering Napoleon wrasses, titan triggerfish, crocodile fish, and many different species of gobies tucked among an abundance of hard and soft corals. Participants will also have the unique chance to snorkel Palau's Jellyfish Lake and then dive the Chandelier Caves. Visit the trip page for all the details.

Midriff Islands in the Sea of Cortez, August aboard the Rocio del Mar Liveaboard, August 19 - 26, 2017. Join Christy and Brice for an unforgettable week of diving and citizen science in the diverse and dynamic Sea of Cortez, home to a wide range of creatures including nudibranchs, blennies, jawfish, rays, guitarfish, sharks, eels, octopuses, seahorses, and much more! In addition to numerous fish and invertebrate families, participants may also get to observe pilot and sperm whales while in transit. The plankton-rich currents of the Pacific along the coast of California and Mexico, along with the sheltered waters of the Sea of Cortez, also create a great opportunity to encounter whale sharks and manta rays. In fact, Jacques Cousteau once called this region, "the aquarium of the world." And top-side scenery is as spectacular as below the water. Participants will spend 7 nights aboard the magnificent Rocio Del Mar liveaboard, a spacious 110-foot vessel complete with a fantastic crew. Visit the trip page for all the details.
