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 ...

Human Impacts on Great Lakes Walleye Sander vitreus Structure, Diversity and Local Adaptation

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Artificial propagation and wild release may influence the genetic integrity of wild populations. This practice has been prevalent in fisheries for centuries and is often termed ‘stocking’. In the Laurentian Great Lakes (Great Lakes here‐on), walleye populations faced declines from the 1950s to the 1970s, prompting extensive stocking efforts ...

Categorial versus naturalized epistemology

open access: yesAnalytic Philosophy, Volume 66, Issue 4, Page 658-673, December 2025.
Abstract How do we know what kinds of things constitute knowledge or justified belief? Naturalized epistemology is committed to denying a priori insight into the kinds of kinds that are and are not knowledge or justification makers. By contrast, it is argued here that knowledge of these matters is a priori knowledge of a special kind.

Neoichnology and sediment distribution in tidal flats of the mud‐dominated mesotidal Mira River estuary (Portugal)

open access: yesSedimentology, Volume 72, Issue 7, Page 2201-2238, December 2025.
ABSTRACT Invertebrate burrow morphologies and distributions are presented for the tidal flats of the middle and lower reaches of the tide‐influenced (mesotidal), mud‐dominated Mira River estuary (SW Portugal) as an analogue for interpreting the ichnology of palaeoestuarine successions.
