Absent natural population control, invasive red lionfish Pterois volitans (hereafter, lionfish) have reached record densities in the northern Gulf of Mexico (nGOM), though the role of density dependence on their population dynamics remains poorly understood. This study examined the effects of population density, sex, and habitat on lionfish condition (i.e. mass relative to total length) and size-at-age. Lionfish density was estimated with a remotely operated vehicle during 2010-2017 at a series of nGOM natural (n = 16) and artificial (n = 22) reefs, and individual lionfish (n = 3296) were sampled at additional reefs in the same system between 2013 …
