  abstract = {{T}here is an increasing concern that invasive lionfish will have dramatic impacts on native reef fish assemblages in the {C}aribbean. {H}owever, the intensity and speed of such changes will probably depend on the initial structure of each assemblage and on the lionfish population characteristics. {T}he species composition of native fishes, diet and size structures were analyzed on a protected {V}enezuelan reef, through visual census on zones with and without lionfish, 1 and 3 years after the first sighting of {P}terois (lionfish). {L}ionfish mean density +/- {A} {SD} increased from 30 +/- {A} 83.5 (n = 22) to 121 +/- {A} 164 ind ha(-1) (n = 22), with an important increase in lionfish over 30 cm and the near absence of juveniles. {N}ative species richness and densities remained stable through time. {N}o significant change of native fish assemblage structure, species richness and density of potential {P}terois prey, predators and competitors was found over time, but zones with lionfish had significantly higher levels of prey and predators, and significantly different fish assemblage structures. {M}ost importantly, there was no interaction between time and the presence of {P}terois on these metrics. {O}ur results may suggest that: 1-a healthy composition of the initial structure of the reef fish assemblage may moderate the early impact of lionfish, and the observed lionfish densities (mean +/- {A} {SD} = 121 +/- {A} 164 ind ha(-1), n = 22) were not sufficient to induce a significant change in the assemblage; and 2-lionfish probably select zones where species richness and density of prey are the highest.},
