Tagging Studies Reveal Secrets of Lionfish Movement

Starting in the 1980s, Indo-pacific Red Lionfish were introduced to the Atlantic Ocean. Since then, they have expanded exponentially due to their reproductive capacities, voracious appetites and lack of predators. Due to this rapid expansion in the western Atlantic and Caribbean, it has become increasingly important to understand how individuals move during various life history stages, as this may have critical implications for population control and management.

Information on fish movement and growth is primarily obtained through the marking and tracking of lionfish with external tags. Using data from various studies of tagged lionfish, researchers have found that:
  • Lionfish have high site fidelity, sometimes staying on the same coral heads for months.
  • Lionfish appear to spawn in the late evening hours.
  • Lionfish show movements up and down reef walls from as shallow as 18m to over 50m in a single day.
  • Some lionfish do move.
This information helps determine where and when removal efforts are likely to be successful. For example, in systems where lionfish exhibit extremely high site fidelity and small maximum ranges, localized population control may be feasible since lionfish removed from a given habitat would be replaced largely through larval recruitment rather than migration of older individuals. However, since lionfish grow extremely rapidly (averaging 0.46 mm/day, but reaching as high as 0.78 mm/day), localized control efforts would need to be carried out frequently in order to maintain a younger, smaller population.

Further tagging studies will only enhance our knowledge of invasive lionfish and how to manage them. Upcoming projects include utilizing a closely arranged array to continuously track lionfish and determine home range, daily activity routines, feeding and spawning activity and drivers of movement.


What is a Coral Reef?

Often referred to as “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species. Reefs provide homes for more than 4,000 species of fish, 700 species of coral, and thousands of other plants and animals.

Coral reefs are the rainforests of the sea.
The architects of coral reefs are hard corals, which -- unlike soft corals -- have stony skeletons made out of limestone that is produced by coral polyps. When polyps die, their skeletons are left behind and used as foundations for new polyps. An actual coral branch or mound is composed of layer upon layer of skeletons covered by a thin layer of living polyps. If you think of a coral reef as a bustling city, then each coral colony is like a single apartment building with many rooms and hallways that house different marine species.

The Florida Keys are home to the third largest living coral reef system in the world. The Florida reef tract extends from Soldier Key, located in Biscayne Bay, to the Tortugas Banks. The tract stretches for nearly 150 miles in length and is about four miles wide. These reefs are intricately tied to our area’s economy, attracting tourists for diving, snorkeling, and other recreational opportunities and providing homes for many commercially important fish species. Take a moment to explore and learn about the biology of corals, about coral reefs, and why reefs are important to the economy.


Sanctuary Seminar Begins Tuesday

FKNMS you to a series of lectures to learn about the wildlife, ecology and history of the Sanctuary and Florida Keys National Wildlife Refuges.

200,000th Volunteer Fish Survey Conducted

We are very excited to announce that REEF just celebrated the addition of its 200,000th survey to the Volunteer Fish Survey Project database. The lucky 200k survey was conducted by long-time REEF expert surveyor, Kreg Martin on Oct. 15, 2015 at Cape Kri in Dampier Strait, Raja Ampat, Indonesia. He reported 208 species in 68 minutes!

Started in 1990, REEF's Volunteer Fish Survey Project is now the largest marine citizen science project in the world. With more than 15,000 divers participating and more than 3,600 fish species tallied at thousands of sites, this program is shaping our understanding of our ocean worldwide. REEF is grateful for the contributions of all volunteer divers to preserve the "blue" environment by providing much-needed information about what happens below the ocean’s surface.


Our Mission
Sanctuary Friends Foundation of the Florida Keys supports the Florida Keys and the Florida Keys National Marine Sanctuary (FKNMS) in the preservation, restoration, and sustainable use of our coral reef ecosystem, from the uplands to the deep sea. We focus on development of community support and advancement of public awareness, education, outreach and scientific research.
