Abstract Predation from the invasive Indo‐Pacific lionfish is likely to amplify declines in marine fishes observed multiple ocean basins. As invasion intensifies and expands, there an urgent need identify species that are most at risk for extirpation—and possible extinction—from this added threat. To address gap inform conservation plans, we develop apply a quantitative framework classifying relative vulnerability of based on morphological behavioural traits known influence susceptibility predation (e.g. body shape, water column position aggregation behaviour), habitat overlap with lionfish, degree geographic range restriction. Applying across invaded Caribbean Sea ahead front southwestern Atlantic revealed identity least 77 relatively small ranges be affected by predation. Trait‐based scores significantly predict probability appearing within diets region. Spatial richness analyses reveal hotspots vulnerable Bahamas, Belize Curaçao. Crucially, our identifies 29 endemic Brazil, which has not yet been colonized lionfish. Of these, suggest reefs around offshore island groups occupied dozen highly range‐restricted as priorities intervention should spread Observations rate average 5 years (with median nearly 2 years) elapses first sighting maximum densities. This lag may allow managers mobilize plans suppress priority locations. Our also provides method assessing cryptobenthic and/or deep‐reef fishes, population‐monitoring data limited.

Abstract Since its introduction in the Western Atlantic more than 30 years ago, lionfish ( Pterois volitans/miles complex) has spread throughout Gulf of Mexico, Caribbean and Tropical Atlantic, with massive unprecedented ecological impacts. This invasion is among most studied marine fish invasions but very little still really known about population dynamics species factors ultimately governing abundance. The was first documented on Saba Bank 2010 rapidly increased abundance till end 2014. In this note we document rise subsequent decline density thereby describe species’ third apparent local boom-bust event for Greater Caribbean. We also gradual increases mean size Eastern that coincided increase Contrary to previously epizootic disease outbreak associated crash observed Mexico were unable find any signs occurrence disease. suggest might have been due non-local causes. Boom-bust are often witnessed biological critical implications both understanding managing invasive species. While underlying cause remains unknown, our work suggests region, feedback mechanisms gradually developing can help level-off deleterious excesses

The bioinvasion of lionfish Pterois volitans (Linnaeus - 1758) in brazilian waters: an urgent necessity to create strategies to contain the expansion of the species in Brazil

The lionfish Pterois volitans (Linnaeus, 1758) is considered the most well-established fish species in non-native regions around world, causing severe environmental damage and risks for food chain. In Brazil, was reported first time 2014 State of Rio de Janeiro, currently, P. observed more eight States, being its high level occurrence Northern region, which contains an immense biodiversity that has not been totally cataloged yet. Based on that, this study aims to ratify occupation permanent residence Great Amazon Reef System (GARS), alert urgent need developing control strategies invasive Brazil. new specimens were collected Amapá, between 2021 2022, during commercial lobster fishing, using method “Caçoeira”, covering 70 100 meters depth, while snapper with manzuá, 78 102 depth. laboratory, individuals measured total length (TL) weight (TW). 21 from GARS, TL ranged 21,5 35,6 cm average 29,43 cm, TW 150,0 733,0 g, 413,8 g. These adult reinforce stabilization lionfish, have probably completed reproductive cycles requiring action by agencies invasion becoming a future impact native biodiversity.
