Abstract
Lionfish were collected, weighed and measured, and their ages estimated by counting opaque zones in otoliths from 3,296 lionfish sampled between 2013 and 2017. This dataset supports the publication: Dahl, K., Edwards, M., & Patterson, W. (2019). Density-dependent condition and growth of invasive lionfish in the northern Gulf of Mexico. Marine Ecology Progress Series, 623, 145–159. doi:10.3354/meps13028.
Purpose
To describe and document life history characteristics of invasive lionfish over a long time scale of invasion. We aimed to document the effect of sex, population density, and habitat type on lionfish relative body condition and size-at-age with a focus on determining whether lionfish populations in the region were nearing carrying capacity.
