The research group on Live Preys, Larviculture and Ecotoxicology, was established as such in 1984, and owes its origin and current diversity of research areas to initial studies focused on the biology, ecology, biodiversity and use in aquaculture of the branchiopod crustacean Artemia. The use of Artemia nauplii as live preys in marine larviculture, and the lack of knowledge on the biodiversity and biogeography of the species of the genus both on local and global scales, have largely conditioned the evolution of the team's lines of research during the first 25 years of existence.
