REEF Staff Dr. Christy Pattengill-Semmens (Director of Science) and Lad Akins (Director of Special Projects), joined over 300 scientists, resource managers, and fishers at the Gulf and Caribbean Fisheries Institute (GCFI) meeting last week in Corpus Christi, Texas. All three of REEF's major programs were represented.
Christy presented a research poster on an analysis of patterns of rarity in fishes in the Caribbean basin using the REEF Volunteer Fish Survey Project database. Over 90,000 surveys from our citizen science program were used to explore where the rare things are, and why some places seem to have so many more of them than others.
Lad co-chaired a session on Invasive Lionfish, featuring 21 talks on the current state of lionfish research and control efforts in the Atlantic. During this session, REEF Affiliate Scientist, Dr. Stephanie Green, presented her findings on the efficacy of lionfish derbies. Her research shows that one-day derby events like the ones REEF coordinates in Florida and the Bahamas can result in a significant reduction of lionfish densities, up to 70%, over 180 square km, all the result of volunteer teams. Lad and Nova Southeastern University graduate student and upcoming REEF Intern, Adam Nardelli, also presented a research poster on the demographics of participants in the 2013 Key Largo Lionfish Derby.
And finally, REEF Grouper Moon Project collaborators, Dr. Brice Semmens (Scripps Institution of Oceanography) and Dr. Scott Heppell (Oregon State University) both presented talks during the fish spawning aggregation session, and we were also joined by collegues from the Cayman Islands Department of Environment (CIDOE). Brice presented findings from our research using Passive Acoustic Monitoring on a multi-species spawning aggregation on Little Cayman, and Scott presented a theory for why spawning aggregations have collapsed around the world and how our Grouper Moon research can be used to help inform future protection efforts.
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:
- Researchers from Western Washington University, Simon Frasier University, and the SeaDoc Society are all using REEF data to evaluate the status of echinoderms in the Pacific Northwest and how the rapid spread of seastar wasting disease will affect populations.
- Scientists from Washington Department of Fish and Wildlife are including REEF data in an evaluation of the status of Northern Abalone in Washington State.
- A researcher from RSMAS at University of Miami is using REEF data from throughout the Caribbean basin to evaluate populations of predators.

We say it often - REEF is what it is because of our fantastic members. The grassroots nature of the organization is reflected in all aspects of our work, including the amazing volunteers like Audrey Smith who help with daily operating tasks at REEF HQ, the networks of regional REEF partners who enlist new REEF members and provide continuing education and survey opportunities for active surveyors, our members who generously support REEF with financial donations, and of course the thousands of survey volunteers who submit marine life surveys each year.
As the corps of active and experienced REEF surveyors has grown, we have been fortunate to have some of those members take their support and interest in REEF to the next level by forming local REEF groups. Two such REEF "clubs" are FIN (the Fish Identification Network) and the Pacific Northwest Critter Watchers. FIN is a REEF club based in Maui, and is touted as an opportunity to join friends and fellow fish lovers in exploring the coral reefs of Maui. The club is for all interested divers and snorklers, and promotes marine conservation and the objectives of REEF. FIN was founded by Terri and Mike Fausnaugh (Mike is also a member of the REEF Hawaii Advanced Assessment Team (AAT)) and is supported by the cadre of REEFers that REEF partner, Liz Foote of Project S.E.A.-Link, has generated in Hawaii through the years. There are monthly (sometimes weekly) FIN dives at various beaches on Maui and at every event FIN folks set up a REEF station on the beach with survey materials and identification reference guides in an attempt to lure in new afishianados! The PNW Critter Watchers encourages all divers in Washington and Oregon to become underwater naturalists. Through training and quarterly REEF survey dives, Critter Watcher founders and REEF Pacific AAT members, Janna Nichols and Wes Nicholson, aim to put the fun in critter watching and promote REEF surveying in the Pacific Northwest. Janna also maintains a Critter Watchers website that includes a fish of the month feature, an events listing, unusual sightings reported by fellow Critter Watchers, and congratulations to REEF surveyors who have advanced through the REEF experience level system.
These home-grown REEF clubs are a great way to help spread the fun and enjoyment of REEF surveying to a local dive community. We are grateful that we have such enthusiastic and supportive volunteers who are willing to help spread the REEF word. These on-the-ground activities could never be accomplished without your help!
Last Summer during a dive with Pacific Adventure Charters in Hood Canal, Washington, a group of REEF Pacific Advanced Assessment Team (AAT) surveyors came across something unexpected. As part of REEF’s funded project with The Russell Family Foundation, the team’s goal was to look for invasive tunicates and do REEF marine life surveys on several previously unsurveyed sites. While they found the invasive tunicates they were looking for, they also found a derelict fishing net that was damaging fragile habitat and ensnaring marine life.
AAT members, Pete Naylor, Steve Rubin and Janna Nichols found the abandoned gill net on a wall, amid large growths of Cloud Sponge (Aphrocallistes vastus), one of Puget Sound’s rarest and longest lived animals and an invertebrate species monitored in the REEF Pacific Northwest Volunteer Survey Project program. As the name implies, cloud sponges form pale, irregular cloud-shaped colonies, which can be more than ten feet across and seven feet high. These colonies attach to rocky surfaces and provide complex habitat for a variety of marine species. The nearly invisible monofilament derelict gill net was draped over and around the cloud sponge colonies, clearly causing damage. Dungeness crab and other invertebrates lay dead and entangled in the net’s folds.
Concerned by what she saw that day, Janna contacted the Northwest Straits Commission, a regional marine conservation initiative that runs a derelict gear removal program. Given the net’s direct threat to the safety of divers and that it was causing clear harm to marine life and habitat, the Commission made removing the gill net in Dewatto Bay a high priority. After an initial search in the Fall 2007 that failed to locate the net, the net was successfully located with the help of REEF members Keith Clements and Rob Holman. Trained commercial divers removed the net from the fragile cloud sponge reef earlier this month. It was clear during the removal operation that the net had swung in the current and scraped much of the rocky outcrop clean of marine life. But cloud sponge colonies were still present on either side. The initial REEF survey conducted last summer will now serve as a baseline for future monitoring. A REEF team, including Janna, Pete and Steve are planning to revisit the site in May to note any signs of recovery.
Jeff June, the Initiative’s derelict gear program lead commented about the collaborative effort: “This particular net removal effort shows the importance of the REEF divers participation in these types of projects. We would have probably never known there was a gillnet in the vicinity of these amazing sponges had the REEF folks not been monitoring the site.”
Janna made this observation about encountering the net: “From a diver's point of view, it's really shocking to see firsthand just how much marine life a derelict net can snare and kill. We spend hours underwater all around the waters of Washington State, and are specifically attracted to viewing and protecting all the amazing wildlife we can on each dive. Seeing trapped and dead or dying fish and invertebrates is a real shame. Derelict gear not only poses hazards to all the marine life they continue to snare and kill, but to divers as well, because of the entanglement hazards.”
If you are a Pacific Northwest diver, you can report derelict fishing gear in Washington through the WDFW Sighting Form. Other states have similar programs.
REEF scientists, volunteers and collaborators will be in the Cayman Islands next month for the 8th year of the Grouper Moon Project. Thanks to a three-year grant awarded last year by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF has greatly expanded the critical conservation research conducted as part of this study of Nassau grouper spawning aggregations. We will have teams on all three of the Cayman Islands conducting field research as part of the project, “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”. The Little Cayman team will continue the long-term visual monitoring of the large aggregation located there. Work on Grand Cayman and Cayman Brac will focus on studying the remnant aggregations that remain on these islands after years of fishing. There is currently a harvest ban in effect for all aggregations in the islands. This ban is set to be lifted in 2011 unless the extension of the protections are warranted.
Despite logistical complications, weather anomalies and difficulties locating fish, the Grouper Moon Project had a successful year of field-work in 2008. The team conducted preliminary work on Cayman Brac and Grand Cayman, tagging Nassau grouper with pinger acoustic tags and then installing hydrophone arrays to track the movements of those tagged individuals. Studies were also conducted to better understand the patterns of recruitment by larval and juvenile Nassau grouper to the islands. In addition, members of our team attended major scientific conferences both nationally and internationally, and presented aspects of our research and findings to date.
In the Winter of 2002, REEF launched the Grouper Moon Project with a ground breaking expedition to observe the Nassau grouper spawning aggregation off the western tip of Little Cayman and to develop a protocol for monitoring their numbers and activity at the site. Since that first year, REEF has coordinated annual efforts to monitor and study the Little Cayman Nassau grouper aggregation. The project has grown in scope to include an ambitious acoustic tagging research project, juvenile habitat and genetics studies, and early results have been published in the scientific literature. This work is a collaboration with the Cayman Islands Department of the Environment and researchers from Oregon State University.

As part of REEF's efforts to increase awareness about the invasive lionfish, train removal teams and develop regional response plans, REEF recently conducted a series of workshops, talks and lionfish removals in partnership with the Gray's Reef National Marine Sanctuary (GRNMS) in Georgia and the Cozumel Marine Park in Mexico. Combined the two projects held in July 2009 included 15 talks to more than 370 people.
The Gray's Reef project included a meeting of Sanctuary personnel from the Florida Keys, Flower Garden Banks and Gray's Reef National Marine Sanctuaries, working to develop a regional coordinated response plan. Sanctuary and REEF staff also conducted two days of lionfish collecting and handling dives, including the removal of 54 lionfish averaging almost 30 cm from sites just outside the GRNMS boundaries. Talks to the general public, Sanctuary Advisory Council and Georgia Law Enforcement working groups also helped increase awareness of the lionfish issue and conveyed removal plans for the region.
Immediately following the Gray's Reef project, a week-long series of workshops and talks were held in Mexico to initiate development of the Mexican regional lionfish response plan focusing on the Yucatan. An initial day-long meeting included over 40 representatives, including national environmental regulators, regional marine park directors, conservation and science groups, academia and the Mexican Navy. Presentations and discussions resulted in the development of an early detection/rapid response plan. The plan was then unveiled in numerous public and key user group talks including those to dive operators, fishermen, medical/first responders and university groups. Training dives with Marine Park staff also resulted in the removal of 3 juvenile lionfish from local Cozumel reefs.
