The effects of stocking density on the production and health of olive flounder (Paralichthys olivaceus) in RAS

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Olive flounder (Paralichthys olivaceus) is known for its growth performance in aquaculture. Fish are typically raised at high densities in recirculating aquaculture systems (RAS), which may impact animal health. Flounder (55.2 ± 16.3 g) were stocked at three densities: a low density (LD) of 3 kg/m2, medium density (MD) of 6 kg/m2, and high ...

Categorial versus naturalized epistemology

open access: yesAnalytic Philosophy, Volume 66, Issue 4, Page 658-673, December 2025.
