Following the most recent Indo-Pacific Lionfish expedition at Stuart Cove’s in Nassau, Bahamas, we kicked off the next phase of our critical research on this invasive species in Eleuthera. Supporters, Trish and David Ferguson, served as hosts for the week. Earlier this summer, REEF staff set up 11 study sites, tagging 30 fish on six different patch reef and clearing the other 5 sites of lionfish. This past week, I revisited those tagging sites and documented any movement of lionfish. We then following up with early morning, mid-day and evening activity observations to see what the fish were up to and when. The observations involved pre-sun up dives and 2-3 hour bottom times. With some very early and late dive times, the data collected is showing interesting patterns of low light activity.
After five days of intense data collecting at the Ferguson’s we headed down to Cape Eleuthera to meet with staff and students at the Island School and Cape Eleuthera Institute(CEI). The facility is completely self contained, producing their own electricity via solar and wind, their own biodiesel, raising cobia and tilapia in an aquaculture facility and even growing their own hydroponic vegetables. A very impressive operation and an incredible group of staff and students. We were able to conduct collecting and dissecting demonstrations for the coral research class and then do a packed house talk to all of the staff and students from TIS as well as a number from the local Deep Creek Middle School. There is strong interest in collaborating on future lionfish studies as well as incorporating fish surveys into the regular research curriculum at the IS and CEI. Look for future REEF projects to be scheduled here in 2009. Visit our Lionfish Research page for more information.
Last Friday, May 15th, America celebrated Endangered Species Day. While very few marine species have technically been declared as endangered, many of the critters that REEF volunteers see while conducting marine life surveys have experienced declines in recent years. REEF programs and data provide much needed information for scientists and resource agencies charged with evaluating the status of such species. A recent example is a National Marine Fisheries Service (NMFS) proposal to list 5 species of rockfish in the Puget Sound under the Endangered Species Act (ESA). The status review was just published on April 22 and REEF data were extensively used in the assessment. This example highlights the value of REEF data as a fisheries-independent data source; such information is critical for those species that are too rare to be targeted for harvest. A copy of the assessment is posted online.
The Nassau grouper, which is the focal species of REEF’s Grouper Moon Project, has been classified as endangered under the IUCN’s Red List. The Grouper Moon Project is a collaborative conservation program between REEF and the Cayman Islands Department of the Environment to study one of the last known large Nassau grouper spawning aggregations in the Caribbean. Grouper Moon Project lead scientist, Dr. Brice Semmens, will be presenting the ground-breaking findings of this research during a special one day session to be held in the Ocean Hall at the Smithsonian’s National Museum of Natural History this Wednesday, May 20th. "Beyond the Obituaries: Success Stories in Ocean Conservation" will feature some of the good news coming out of work being conducted in the oceans. Brice’s talk, along with all of the success stories, will be webcast online. The Grouper Moon talk is scheduled in the Coral Reef session, which is from 2-3:25.

Long-time REEF supporters, Les and Keri Wilk of ReefNet, recently discovered and photographed a distinctively marked population of the Greenbanded Goby, Elacatinus multifasciatus, on the island of Utila, Honduras. The population was distinguished by a prominent red stripe across the cheek that is not found on other populations of Greenbanded Gobies, as well as more numerous green bars on the body. The Wilks contacted Dr. Benjamin Victor (coralreeffish.com), a reef fish taxonomic expert, who conducted a regional genetic comparison of Greenbanded Gobies to evaluate hidden diversity within this colorful reef fish. As part of the study, the REEF database was used to document the current geographic range of the species. Dr. Victor's results identified the unique looking fish to be a separate species that is now called the Redcheek Goby (E. rubrigenis). He also discovered that, based on genetic results, Greenbanded Goby along coastal Panama, despite looking just like others in the species complex (i.e. a cryptic species, distinguished mainly by differing DNA sequences), are a distinct species that will now be called Panamanian Greenbanded Goby (E. panamensis). The study was published last month in the Journal of the Ocean Science Foundation.
The new species, the Redcheek Goby, replaces the Greenbanded Goby on the island of Utila and has not been sighted at any other location, potentially one of the smallest ranges reported for a Caribbean reef fish. With few exceptions, coral reef fishes have pelagic larvae that spend weeks to months developing in off-reef waters. As a result of this high dispersal ability, most Western Atlantic reef fish species have geographic ranges throughout the Caribbean Sea and adjacent areas. Endemic marine species (those only found in a given region or location and nowhere else in the world) are generally uncommon in the western Atlantic region. Furthermore, many of these widespread species show little, if any, variation in their genetic patterns between areas, particularly within the bounds of the Caribbean Sea with its many stepping-stone islands. Nevertheless, some groups of fishes, presumably those with more-restricted larval dispersal and strong local selection, show interesting patterns of endemism, genetic structure, and cryptic speciation within the region, for example among the Elacatinus cleaning gobies (e.g. Sharknose, Cleaning, Neon, Yellowline, etc.). Those reef fish taxa that contain cryptic species can provide valuable insights into the processes of speciation and the biogeographic history of the region, but also seriously challenge the traditional species concept. The results of Benjamin Victor's study highlight these challenges.
REEF is proud to be able to contribute to scientific studies such as this one. We are also thrilled that fishwatching by amateur non-scientists like our Fish Survey Project volunteers has been elevated beyond just a hobby, and is increasing the state of knowledge about reef fish diversity.

Field Surveys – Eighteen REEF members joined Drs. Christy and Brice Semmens earlier this month on a Field Survey to the Sea of Cortez aboard the Rocio del Mar live-aboard. The team conducted over 300 surveys in 20 locations around the Midriff Islands, many of which were new to the REEF database. It was a great trip, with 130 species of fish found, beautiful topside scenery, and pods of sperm and pilot whales! Find out more about REEF Trips.
Lionfish Derby – The second of three lionfish round-ups in the Florida Keys was held last week off Marathon (FL). During this one-day event, several teams participated to collect this voracious predator off local reefs. The third derby is scheduled for November 13 in Key West. Find out more about REEF’s Lionfish Program.
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 Fisheries are using REEF data to conduct stock assessments on parrotfishes in Puerto Rico and US Virgin Islands.
- REEF Advanced Assessment Team members joined the Living Oceans Foundation's Global Reef Expedition in the Bahamas. Scientists from LOF are now using the REEF data collected to generate species distribution maps of remote areas including Cay Sal Bank.
- A researcher from the Gilbert Ichthyological Society at the Burke Museum in Washington is evaluating the distribution of the two sub-species of blue rockfish along the west coast.
