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.

Release of Invasive Lionfish: A Guide to Control and Management

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).

2013 Summer Lionfish Derby Series Announced

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.

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 Herb Gruenhagen. Herb has been a REEF member since 2001, and has conducted 208 surveys (all in his home state of California). He is a member of the Pacific Coast Advanced Assessment Team as an Expert Surveyor. Here's what Herb had to say about REEF:

When and how did you first volunteer with REEF or become a REEF member?

In July 2000, the San Diego Ocean Foundation sunk a Canadian Destroyer as an artificial reef. I was one of several divers who performed both fish and invertebrate surveys, using transects, quadrats, and REEF Roving Surveys. When the San Diego Oceans Foundation decided to become a REEF Field Station, I volunteered to become a volunteer REEF instructor. I have been teaching a REEF class each month in San Diego since that time.

What are some of the highlights of your local diving?

I dive the La Jolla Shores most of the time, and it is always changing. There are the resident species, the transients, and the seasonal ones. The resident species will always be there no matter what. The transients can be the many pelagic species that the currents bring in. For example, a while back, we are seeing several different species of jellyfish and the leopard sharks are returning to the warmer water shallows near the Marine Room. The seasonal species are really the special surprises. During the early spring the nudibranchs come out to start their mating, and in the winter, we have a ‘white’ Christmas with all the Market squid schooling, mating, and laying their white finger-like egg cases. Other special surprises can be molas, baby grey whales, midshipman, mantis shrimp, wolf-fishes, and even Finescale Triggerfishes.

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

Doing REEF surveys really highlights the many different variations that a given species can take on. Being a REEF surveyor gives you the ability to recognize new species from common species, and all the many variations within the same species. Paying attention to all the details is really important to getting a good ID. I try to get a good image of the fish and ask for help when I’m not sure.

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

After all the years of teaching the courses, I’m just really glad to see local divers coming to my class to expand their knowledge of the local marine life, whether they do one survey or many surveys. I love watching the learning process and expanding the students minds of the many wonderful forms of marine life we have here to enjoy and need to perserve for future generations.

Do you have a favorite local (or not) REEF field station or dive shop?

The REEF Field station is the San Diego Oceans Foundation, but the facilities that we use is Ocean Enterprises in San Diego. Ocean Enterprises has been very supportive over the years and everyone really appreciates the use of their classrooms, computer and projector and its central location in the city. Thank you Ocean Enterprises for your many years of support.

What is the most fascinating fish encounter you’ve experienced? What is your favorite?

Well, of course photographing species new to science or that is rare or very uncommon is a highlight. I have photographed several fishes and nudibranchs that fall into one of those categories. My most fascinating fish that I have seen is the Specklefin Midshipman, Porichthys myriaste. We see many juvenile Plainfin Midshipman in the winter, but the Specklefin were quite a find! One of my favorite fishes is the Sarcastic Fringehead. They are one of the few fishes that see you as a threat and will interact with divers and their photo gear. They will charge out of their breeding holes (ok, we are talking about a 6” fish) at the camera lens, thinking they are seeing ‘another’ fringehead in the lens. They will bite all your cables and your finger and charge back into their hole. They will also interact with each other and fearlessly defend their breeding holes by opening their mouths at each other beyond the stretching point.

Herb teaches free Southern California Marine Life ID classes the third Wednesday of each month. Join him!

Wellwood AAT Team, Summer 2007

REEF has just completed our final assessment report for our five-year Wellwood Restoration Site monitoring project. Before I share some results from our study, let me give you a little background information and please visit our website to view our full report http://www.reef.org/programs/monitoring/wellwood. The M/V Wellwood, a 122-meter Cypriot-registered freighter, ran aground on August 4, 1984, on Molasses Reef off Key Largo, Florida, part of the Florida Keys National Marine Sanctuary (FKNMS). The ship impacted the reef’s upper fore reef and subsequently remained aground for 12 days. The grounding destroyed 1,285 square meters of living coral reef and injured 644 square meters of coral reef framework. Prior to the grounding, the area was a transition zone with high relief coral formations. The grounding transformed the area into a flattened, barren pavement covered with coral rubble. 

The study area of this project included a portion of the grounding area that is being restored and two adjacent reference sites. The Restoration site surveyed included restoration modules and contiguous low profile hardbottom areas adjacent to and in between the restoration modules. Nearby high profile reef, ledges, and undamaged/unrestored reef were not included as part of the Restoration Site. A north and south undamaged reef area were both used as two control sites to compare fish sighting data between the Restoration area and the natural (control) reefs.

REEF’s study focused on fish assemblages and not the coral and invertebrate communities. A team of Advanced Assessment Team REEF Experts conducted Roving Diver Technique (RDT) surveys in addition to belt transect surveys on the Wellwood restoration site and two adjacent natural reef sites seven times during Year 1. The team visited the sites once prior to restoration (May 2002) and 13 times after restoration was completed, monthly for the first three months, quarterly for the following year and semi-annually thereafter. An average of 12 surveys of each survey type was conducted during each survey effort. While REEF surveyors used the RDT surveys to collect sighting frequency and abundance data on fishes over all three reef areas, the belt-transect method was used to collect density and biomass data on fish taxa. These two methods used together give us a snapshot of how the restoration site is recovering in terms of fish assemblages as compared to the two non-impacted, adjacent reef areas.

Obviously, the most notable observation a diver makes when diving on the Restoration site is one of just how long it takes coral reefs to recover after devastating ship impacts. The Restoration site shows little resemblance to the surrounding non-impacted reef sites. The areas surrounding the Restoration site are high relief reef areas dominated by reef building corals with some very old colonies of Star coral (Monastrea annularis) and Elkhorn coral (Acropora palmata), old to the tune of thousands, not hundreds of years old. Age is important here since it takes a long time for coral colonies to rebuild structure and relief that attract different fishes over time. The smaller overall fish populations and absence of many species of fish on the damaged site are both conspicuous and the lack of coral structure makes it easy to destinguish the Restoration area from the surrounding reefs even 23 years after the initial ship grounding. However, there are signs that fishes are very slowly recruiting onto the Restoration site.

During the monitoring period (2002 - 2007), a total of 165 species were recorded at the Restoration site, 189 species at the North reference site and 207 species at the South reference site. The Restoration site recovery is clearly aided by the addition of restoration modules (2002), increasing the amount of available habitat suitable for reef fish communities, think vertical habitat here, and recessed areas underneath these modules for fish to shelter. At the Wellwood grounding site, the overall fish diversity as well as density and biomass of most key fish families continue to be less than that of the two nearby, non-impacted reefs that were selected as monitoring reference sites. Parrotfish and surgeonfish appear to be responding the quickest to the restoration efforts, grazing along a recovering hard coral landscape currently dominated by soft corals (Gorgonians). Nearly absent today on the damaged area are sightings of grunts and snappers, both of which are seen in high frequency and abundance on surrounding reef sites with plenty of relief for them to take cover. Residency of fish, movement patterns and habitat usage are all important indicators of reef recovery. So are linking coral, invertebrate, and fish studies to see a more complete picture of how the Restoration site is improving. There are signs outside of the slowly improving trends the data show such as a little Redspotted hawkfish that has taken residence on one of the modules with lots of Ken's Staghorn coral affixed.

Many more studies are necessary to properly evaluate recovery dynamics for reefs and since most reef recoveries worldwide are hampered by other anthropogenic impacts such as overfishing, excessive nutrient loading from human pollutants, and global warming stresses, these case studies are critically important in developing mitigation strategies for damaged reefs. For the full report on our Wellwood findings, please visit our website http://www.reef.org/programs/monitoring/wellwood. REEF would like to thank the many individual REEF members who dived on this project over the past 5 years, as well as Quiesscence Dive Shop in Key Largo for dive support, and Ken Nedimyer for photos and his ongoing coral replenishment work. And finally, our thanks to the Florida Keys National Marine Sanctuary for contracting REEF for this project. We hope that this work will continue in order to monitor the long term changes in fish assemblages on the Restoration site.
