Itziar Aretxaga, a long-time REEF surveyor who lives in Veracruz Mexico recently sent in this rare fish sighting report about finding a Swordtail Jawfish. What a great sighting! Here's Itziar's story:

"Earlier this year, I was taking part on an underwater photography competition in Veracruz, Mexico. Every year the diving operators and other supporting organizations launch it as a way to draw awareness upon the diversity and richness of the protected National Park of Veracruz. I had no hope of winning anything as I am a novice photographer with a very basic camera and no illumination, but I wanted to support their efforts. Each of us had a 90-minute time limit to take up to 100 photos.

I saw this jawfish on the sandy area immediately below the buoy in Cabomex, Anegada de Adentro, at about 14m depth. I knew it was not any of the jawfishes I had reported before: face markings, behavior, and burrow type gave it away as a different species. I was set on identifying it more than on making any impression on the competition jury, so I spent my allotted 90 minutes by the jawfish, as motionless as possible, and trying to make it get used to the camera just 15cm away from its burrow. The series of photographs allowed me to identify it as a Swordtail Jawfish (Lonchopisthus micrognathus) based on the body bars and the pointy protruding tail, as described in the sketches of the ReefNet Fish Identification DVD. In looking at the REEF database later, I realized it is extremely uncommon to see this species. So all in all, I felt I had won a big prize in that competition!"

Thanks for sharing, Itziar. If you have a rare sighting or fun find to share, please drop us a note.

Get Ready For the Great Annual Fish Count 2016

During the entire month of July we encourage you to try your hand at conducting your first survey if you're new to our Volunteer Fish Survey Project, or to do a few more if it's been a while.

The GAFC began in 1992 when a small group of recreational divers and marine biologists conducted a visual fish count in California's Channel Islands National Park. The effort was modeled after the Audubon’s Christmas Bird Count and has now grown into an international event.

The ideas behind the GAFC are to:

  • introduce divers and snorkelers to fishwatching and citizen science
  • connect local fishwatchers with each other
  • encourage participation in REEF's Volunteer Fish Survey Project, and
  • help gather data on fish populations around the world

We've revamped the GAFC website, and it's got everything you need to be able to join in the fish counting fun as a participant or to organize your own local event. It can be as simple as hosting a survey dive (throw in a BBQ), or an ID class or presentation about your local fish.

We especially encourage shops, dive clubs, marine science centers and others to organize a GAFC event.

Be sure to visit www.fishcount.org to get the scoop.

See you in the water!

Annual REEF Monitoring Projects in the Pacific Northwest

We recently conducted the 2016 surveys on two important long-term monitoring projects in Washington State. Data have been processed, and results are available for viewing. One of the most surprising results was the high abundance of many species of Young-of-the-Year (YOY, aka baby) Rockfish seen on both projects. This is a very unusual sighting, and possibly a good sign for things to come for these threatened species.

The first project is the Olympic Coast National Marine Sanctuary monitoring project, started in 2003. REEF Advanced Assessment Team (AAT) divers annually monitor fish and invertebrates in this remote area of rugged Washington State coastline. The team documented 100 species of fish and invertebrates, as well as YOY of 10 different rockfish species. Data for 2016 may be viewed here.

The second project began in 2013, and monitors fish and invertebrates in Washington State's San Juan Islands, which are centrally located within the Salish Sea. This project is done in conjunction with the SeaDoc Society, and also uses the AAT members within the region. Data for this project may now be viewed here. Annual results from this project have been important in tracking the spread of Sea Star Wasting disease.

Thanks to our many divers who lent their expertise in diving and identifying fish and invertebrates underwater, as well as the dive charters and donors who help fund these critical projects.

Putting It To Work: New Publication Uses REEF Data to Evaluate Rockfish Populations in the Puget Sound

A new paper out earlier this month in the scientific journal, Ecology and Evolution includes REEF Volunteer Fish Survey Project data as part of a sophisticated analysis of rockfish populations in the Puget Sound, Washington. The paper was published by Dr. Nick Tolimieri, and his colleagues at National Marine Fisheries Service and Washington Department of Fish and Wildlife. Estimating a population’s growth rate and year-to-year variance is a key component of population viability analysis (PVA). However, standard PVA methods require time series of counts obtained using consistent survey methods over many years. The authors of this study used REEF data along with two other fisheries datasets to evaluate the long-term trends of rockfish in Puget Sound, Washington State. The time-series analysis was performed with a multivariate autoregressive state-space (MARSS) model. The authors show that using a MARSS modeling approach can provide a rigorous statistical framework for solving some of the challenges associated with using multiple, sometimes inconsistent datasets, and can reduce the proportion of fisheries assessment cases that are assigned a designation of “data deficient.”

The analysis was part of the 5-year review of the Endangered Species Act (ESA) listing of Puget Sound populations of three rockfish species (Bocaccio, Canary Rockfish, and Yelloweye Rockfish). The three sources of data included in the study were: (1) recreational catch data, (2) scuba surveys conducted by REEF surveyors, and (3) a fishery-independent trawl survey. Because there were too few observations of the three species of rockfish in the data sources to analyze these species directly, the MARSS analysis estimated the abundance of all rockfish. Because Bocaccio, Canary, and Yelloweye are deep water species, they are not often seen by REEF surveyors. The other two data sets showed that these rockfishes declined as a proportion of recreational catch between the 1970s and 2010s. The REEF data suggest that other species like Copper and Quillback rockfish have experienced population growth in shallower depths.

GAFC 2007 - Dive Friends at Yellow Submarine, Bonaire

Thanks to everyone who participated in a GAFC event this summer! This July, over twenty-three events were hosted throughout REEF's survey regions. We are still receiving data from these events and have processed a large amount already!

Since REEF's GAFC's inception in California in the early 90's, it has continued to grow and expand. More people are become involved in REEF by making a meaningful contribution to marine conservation by conducting REEF Fish Surveys. Previous events have generated over 2,000 surveys during the month of July. This year, the New England Aquarium Dive Club hosted an event in Gloucester, MA, with 103 surveyors! 

GAFC is REEF's biggest annual signature event which mobilizes our wonderful partners, volunteers, and dive shops throughout much of our survey regions.  All of whom coordinate their own local events which include offering free REEF Fish ID courses, organizing survey dives/snorkels, and other fun events tied into the theme of counting fish. The GAFC draws local, national (US), and international media attention each year. It reengages veteran REEF volunteers and also serves as a terrific mechanism to expose new ones to what REEF is all about. Though the GAFC takes place each July, it highlights nothing more than what we do year-round - engaging individuals to become active stewards of the marine environment. Volunteers learn by taking REEF Fish ID courses and conducting fish surveys as part of The Fish Survey Project. 

Grant Gove, who attended the GAFC event hosted by the Yellow Submarine Dive Shop in Bonaire, Netherlands Atillies, sent REEF wonderful DVD's of their successful event for our public library! If you hosted an event this year, or participated in one, we encourage you to either mail a DVD to REEF HQ, Post Office Box 246, Key Largo, FL 33037 or email your pictures to intern@reef.org. 

Thank you to everyone who made GAFC successful this year and look forward to next years 17th annual GAFC event!

Grouper Moon researcher and OSU Professor, Dr. Scott Heppell, reviews findings from cleaning station research conducted on the Little Cayman aggregation site at the recent GCFI conference.

REEF Director of Science, Dr. Christy Pattengill-Semmens, and Grouper Moon Scientists, Dr. Brice Semmens (NOAA) and Dr. Scott Heppell (Oregon State University), participated in the Gulf and Caribbean Fisheries Institute (GCFI) meeting earlier this month in the Dominican Republic. This annual meeting brings together scientists, fishermen, resource agency managers, and marine conservation organizations to present and discuss current topics and emerging findings on coral reef resources of the tropical western Atlantic waters. Christy presented a summary of 5 years of fish monitoring on two modified reef areas off Key Largo, Florida: the Spiegel Grove artificial reef and the Wellwood grounding restoration (see next month’s edition of REEF-in-Brief for more information on these projects). Brice was an invited speaker in the special session on Nassau grouper, presenting an overview of the conservation status of the species. During the Spawning Aggregation session, Brice also presented changes in the average size of Nassau grouper that are visiting the Little Cayman spawning aggregation site since it was protected from fishing in 2003. Scott presented a poster summarizing cleaning station research that the Grouper Moon team has been conducting on the Little Cayman spawning aggregation site. Other presentations that included REEF data included a talk by Dr. Todd Kellison from NOAA Fisheries on trends in commercial species abundances in Biscayne National Park and a talk by Nicole Cushion from University of Miami on patterns of abundance in grouper species in the Bahamas.

Introduction

Happy St. Patrick's Day! We show our "green" spirit here at REEF by continuing important conservation initiatives. In this edition, learn about REEF's participation in the 54th annual Boston Sea Rovers international underwater clinic, a visit with Congresswoman Ileana Ros-Lehtinen and a citizen science discussion series recently hosted by REEF in the Florida Keys. Two valuable REEF members learn bi-coastal fish ID and there is one spot left on the Turks and Caicos field survey next month. Last chance to sign up for this amazing conservation diving opportunity!

With best wishes and best fishes,

Dr. Jim Bohnsac is our Science Liaison to the Board of Directors and a Fisheries Biologist with NOAA.  Recently, Jim has been  interviewed several times about the effectiveness of the Dry Tortugas National Park in protecting fish species inside and outside of the protected areas.  The Dry Tortugas lie approximately 70 miles SW of Key West and are an integral part of the greater Keys coral reef ecosystem.
 No-fishing zones studied, Protective areas aim to increase size, number of fish

DRY TORTUGAS NATIONAL PARK - Reeling in a 45-pound grouper used to be just an average day on the water in the Florida Keys. The abundance of behemoth fish attracted anglers from around the world in the early 1900s, including adventurers such as Ernest Hemingway and Zane Grey, who pulled in monsters from the clear, warm depths off Key West. But as Florida's population boomed, the attraction that drew them began to vanish. Anglers were snapping up the larger fish by the thousands. An average grouper caught in the Keys now is about 8 pounds. "We were starting to look like a Third World nation in regards to having blitzed our resources," said University of Miami marine biologist Jerald Ault.

Mr. Ault and others are studying whether putting large tracts of ocean off-limits to fishing in the Keys can help species rebound - and prove a way to help reverse the effects of overfishing worldwide. Federal and state scientists, along with University of Miami researchers, wrapped up a 20-day study on June 9 after 1,710 dives in the region, surveying fish sizes and abundance, in an effort to determine whether it's working. Critics assert that it isn't. They say limiting size and catch quantities, not fencing off the seas, will help restore ocean life.

 The fierce debate has raged between scientists and anglers for years. Some studies suggest the outcome could mean life or death for not only commercial and sport fishing, but for mass seafood consumption as it exists today. Florida has the largest contiguous "no-take" zone in the continental U.S. - about 140 square miles are off limits to fishing in and around Dry Tortugas National Park, a cluster of seven sandy islands about 70 miles west off Key West amid the sparkling blue-green waters that teem with tropical marine life. Nearby, another 60 square miles are also off limits.The region is home to some 300 fish species and lies within a crucial coral reef habitat at the convergence of the Gulf of Mexico, the Caribbean Sea and the Atlantic Ocean.  To see the rest of this story, please visit -

REEF Director of Science, Dr. Christy Pattengill-Semmens, and Grouper Moon Scientists, Dr. Brice Semmens (NOAA) and Dr. Scott Heppell (Oregon State University), participated in the Gulf and Caribbean Fisheries Institute (GCFI) meeting last month in Guadeloupe. This annual meeting brings together scientists, fishermen, resource agency managers, and marine conservation organizations to present and discuss current topics and emerging findings on coral reef resources of the tropical western Atlantic waters. Christy presented preliminary results from an analysis of data from the Florida Keys National Marine Sanctuaries no-take sites (Sanctuary Preservation Areas) as part of the Marine Protected Areas session. Christy also represented 

REEF during the special session on Marine Invasive Species. She presented an overview of the role that REEF's outreach programs and large corps of volunteer divers have played to better understand the impact of the Indo-Pacific Lionfish on western Atlantic reefs and to help slow the invasion of this unwanted species. Christy also participated in a panel discussion that followed the session.

Both Brice and Scott presented recent Grouper Moon Project results during the Spawning Aggregation session. Thanks to funding from the Lenfest Ocean Program at the Pew Charitable Trusts, our grouper work in the Cayman Islands has greatly expanded and includes ground-breaking conservation research. Brice's presentation focused on the expansion of the work to Cayman Brac, an island where the historical aggregation was fished heavily and was assumed to be non-functional. Scott presented exciting findings from a pilot study conducted earlier this year to understand where Nassau grouper larvae go after they are released from the Little Cayman aggregation site.

A Rare Fish Find on Bonaire's Bari Reef

Active REEF surveyor and Advanced Assessment Team member, Patti Chandler and her husband Scott, recently found a new fish species for Bonaire! Scott and Patti, of ReefNet, were in Bonaire as presenters for the Second Annual Fish ID Challenge. Nearing the end of a lengthy night dive on Bari Reef over sand, in 10 feet of water, something very strange was illuminated by their video lights catching Scott and Patti's eyes. It was a clear fish,1 inch in length, with a rounded tail, and large pectoral fins that practically encircled it, giving it an appearance of wearing a tutu with yellow dots.

The little fish was very active in the water column making photography and videography more of a challenge than usual. This fish was a very young juvenile, more precisely described in the scientific community as post larval in the "settling stage". As they were at a loss for its identification, photos of the strange little fish were sent off for identification to Les Wilk, Head of Scientific Research at ReefNet who in turn sent them to Benjamin Victor, who is the recognized expert for juveniles of any kind, especially larvae. Ben is a frequent poster to the REEF Discussion Forums and has a very useful website, www.coralreeffish.com.

Ben made a positive ID for the wacky little fish. It is a juvenile Reef Bass, Pseudogramma gregoryi! The adult version of the Reef Bass looks totally different. Very few reference guides even mention this obscure but beautiful fish. You can see a photo of the adult at on the bottom of this webpage. The new species was reported on Patti's REEF survey and will be added to the species count for Bonaire. Bonaire's Bari Reef is the ONLY place this fish has ever been reported to REEF in the entire Tropical Western Atlantic! Bari Reef was already the number one reported reef for species diversity in Tropical Western Atlantic and this new species just increases the lead.

The Annual Fish ID Challenge is sponsored by Bonaire Dive & Adventure, Budget Car Rental, ReefNet, and Sand Dollar Condominium Resort for promotion of marine education and conservation.
