Two species of lionfish (Pterois volitans and Pterois miles) are the first marine fishes known to invade and establish self-sustaining populations along the eastern seaboard of the United States. We used the recent expansion of Indo-Pacific lionfish (Pterois volitans/miles) throughout northern Gulf of Mexico coastal waters to evaluate the role of stakeholders in documenting and responding to a rapid marine... Invasive species may exhibit higher levels of growth and reproduction when environmental conditions are most suitable, and thus their effects on native fauna may be intensified. Lionfish are primarily red, brown, and white with a striped, zebra-like appearance. Lionfish are a non-native species in the Atlantic ocean. Originally from the Indo-Pacific, lionfish appeared in the Keys in 2009 and have since become a widespread problem throughout the Caribbean.

It is most likely that the introduction of th… The Florida Fish and Wildlife Conservation Commission (FWC) encourages people to remove lionfish from Florida waters to help limit negative impacts to native marine life and ecosystems. An example of an invasive species that has caused problems in America is the lionfish. I think that instinctive human response to how we deal with invasive species is often based on how we relate to the animal in question - which may lead to an ecologically detrimental outcome. Additionally, work on lionfish biology and ecology will continue as the body of knowledge on the lionfish invasion expands. A close up of a Zookeeper filled with lionfish. First documented off the coast of Florida in 1985, lionfish are now found along the Atlantic coast of the United States as well as in the Caribbean Sea... Strategies to control invasive lionfish in the western Atlantic and Caribbean are likely to include harvest and consumption. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The Invasive Lionfish Web Portal, developed by the Gulf and Caribbean Fisheries Institute in partnership with NOAA, supports the management and control of lionfish in conservation areas along the Southeast coast of the U.S. and Caribbean. Contacts include government agencies (federal, state, and municipal), university researchers, non-governmental (e.g., conservation) organizations, commercial fishermen, and citizen scientists. Yasmeen Smalley. Invasive lionfish caught in the park. The accidental introduction of lionfish has caused many environmental and economic consequences, John Mirabella of Castaways in Marathon Key removes spines from a lionfish in preparation for lionfish sushi. New genetic data suggest the red lionfish invasion in the Caribbean Basin and Western Atlantic started in multiple locations, not just one as previously believed, according to a new study led by the U.S. Geological Survey. Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Although each invasion presents unique challenges, communities may adapt to invasive species in similar fashions. Yet, this invasive species has multiplied aggressively over the last two decades to become a serious threat to biodiversity in the marine setting. Sign up for species-specific email alerts. So far, 54 tagged lionfish have been caught across the state. Nonetheless, there are several reasons to be concerned about their presence: Lionfishes are predators that consume and compete with native species. This research addresses a largely untapped social experiment exploring community innovation and adaptation. Norris says he has to do more research into the issue of "bycatch," the unintended trapping of other species, before divers can start using the Chevron traps in the fight against invasive lionfish. A new inexpensive trap … By educating the public about Lionfish, marine biologists hope to prevent future invasions. Whether on land or in the water, invasive species put native ones at risk and upset the fragile balance of an ecosystem. The Red Lionfish, Pterois volitans, is a strikingly beautiful but venomous fish indigenous to the west Pacific. Gulf Stream “Dispersal of the lionfish population along the Atlantic coast was likely helped by Gulf Stream transport of lionfish eggs and larvae,” said Jonathan Hare, co-author of an early NOAA assessment report. Future work might include innovative methods for detection and trapping of lionfish using remote, underwater cameras with software for identification. While NOAA researchers have concluded that invasive lionfish populations will continue to grow and cannot be eliminated using conventional methods, efforts continue to control populations. As part of the U.S. Geological Survey Nonindigenous Aquatic Species database, the distribution of lionfish is tracked over time. Lionfish are an invasive species that have a potential negative impact on native species and habitat. This is accomplished by maintaining a network of contacts across the Region who regularly submit sightings data. Switzer. An update to this article (Schofield 2010) gives the current range of lionfish through November 2010.
