Evaluating the Potential Efficacy of Invasive Lionfish (Pterois volitans) Removals
The lionfish, Pterois volitans (Linnaeus) and Pterois miles (Bennett), invasion of the Western Atlantic Ocean, Caribbean Sea and Gulf of Mexico has the potential to alter aquatic communities and represents a legitimate ecological concern. Several local removal programs have been initiated to control this invasion, but it is not known whether removal efforts can substantially reduce lionfish num...
متن کاملDensity-Dependent Growth in Invasive Lionfish (Pterois volitans)
Direct demographic density dependence is necessary for population regulation and is a central concept in ecology, yet has not been studied in many invasive species, including any invasive marine fish. The red lionfish (Pterois volitans) is an invasive predatory marine fish that is undergoing exponential population growth throughout the tropical western Atlantic. Invasive lionfish threaten coral...
متن کاملInvasive red lionfish Pterois volitans blow directed jets of water at prey fish
Field and laboratory observations of feeding by invasive Pacific red lionfish Pterois volitans were conducted during June through August of 2008, 2009 and 2010 near Lee Stocking Island, Bahamas. Observations of this invasive marine predator revealed a previously undocumented piscivorous behavior. While slowly approaching prey fish, lionfish produce jets of water directed toward their prey. Thes...
متن کاملA non-proteinaceous toxin from the venomous spines of the lionfish Pterois volitans (Linnaeus).
The venomous spines of P. volitans contain a non-proteinaceous ichthyotoxin of low molecular weight. This toxin could be isolated only from spines excised from the living fish; the toxin is apparently destroyed following death, as the extracts of the spines of the dead fish were non-toxic.
متن کاملPredicted impact of the invasive lionfish Pterois volitans on the food web of a Caribbean coral reef.
The invasion of lionfish in the Caribbean is causing grave concern because of its deleterious impacts on coral reef food-webs. We have used an Ecopath-with-Ecosim model to predict the impacts of lionfish invasion on a coral reef community based on pre-invasion fish community data. Forty-six groups were defined, and an initial Ecopath model was balanced with a near-zero biomass of lionfish. In E...
