A recent study published in Ecology and Evolution offers a new approach to traditional mark and recapture studies while providing valuable insight into the growth and movement patterns of invasive lionfish. Lad Akins, Dr. James Morris, and Dr. Stephanie Green teamed up to develop a novel way of visually tagging fish underwater, minimizing both tagging time and fish trauma.
In response to the growing threat of lionfish in the Atlantic and the need for coordinated planning, REEF, NOAA and the USGS are hosting a technical workshop on Non-native Marine Fish Introductions of South Florida in the Florida Keys June 18 and 19. The workshop, jointly funded through a recent Mote Marine Laboratory’s Protect Our Reefs grant, NOAA’s Exotic Species and National Marine Sanctuary Programs and the Gulf and Atlantic States Regional Panel on Aquatic Invasive Species,will bring together personnel from more than 18 different agencies and organizations.
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.
Information on fish movement and growth is primarily obtained through the marking and tracking of individuals with external tags, which are usually affixed to anesthetized individuals at the surface. However, the quantity and quality of data obtained by this method is often limited by small sample sizes owing to the time associated with the tagging process, high rates of tagging-related mortality, and displacement of tagged individuals from the initial capture location.
$2,620 per person double occupancy. Includes: lodging for 7 nights onboard the Aqua Cat luxury liveaboard in an ocean view cabin, all meals and drinks, up to 5 dives per day for 6 days and 2 dives on the last day of diving, and r/t ground transportation from Nassau Airport.
+$200 REEF Program Fee per diver will be added to each package to cover the cost of the group leader, seminar and survey materials.
Working with leading scientists, REEF's lionfish field work is paying off in valuable information needed to address this key issue. Information from the five Bahamas projects conducted thus far this year is being used to help determine the range and extent of the lionfish invasion, as well as to address key questions on age/ growth, reproduction, genetics, parasites and habitat preference.
This popular trip returns in 2012 for the third year in a row. Reserve your space now, it will fill up quick.
$1995 - $2195 per person (depending on cabin type, double occupancy. Includes seven nights on board the Sun Dancer II, all meals and beverages (including well brands of alcohol and Belikin beer), transfers from/to Belize International Airport, five and ½ days of diving up to five dives per day, other standard Dancer Fleet services and amenities.
Introducing our April Fish of the Month, the Red Lionfish, Pterois volitans! We chose this species because April is Lionfish Derby month — REEF's 17th Annual Florida Keys Lionfish Derby & Arts Festival takes place April 23–26, 2026, right here in Key Largo!
Join REEF in a special presentation on the background of the lionfish invasion, biology and ecology of lionfish, impacts of the lionfish and current research findings as well collecting and handling tools and techniques. After attending the Saturday morning workshop, each participant is welcome to attend optional lionfish handling dives on Saturday afternoon and Sunday morning.
In this early paper, staff from REEF and NOAA studied feeding ecology of the invasive lionfish (Pterois volitans). The authors collected stomach content data from fishes taken throughout the Bahamian archipelago. Three relative metrics of prey quantity, including percent number, percent frequency, and percent volume, were used to compare three indices of dietary importance. Lionfish largely prey upon teleosts (78% volume) and crustaceans (14% volume).
