Zooplankton Epibionts in Boreal Lakes: Associations With DOC and Host Community Traits

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Epibiosis in aquatic ecosystems is well‐documented, yet the factors influencing epibiont prevalence and host selection remain unclear. This study investigates how water quality parameters and zooplankton community dynamics influence epibiont prevalence, with a focus on ecological implications.

Influence of Buffer‐Protected Sodium Butyrate Supplementation in the Diet of Penaeus vannamei

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
This study aimed to determine the optimal inclusion level of protected sodium butyrate (PSB) in diets for Penaeus vannamei during the postlarvae to grow‐out phase. A completely randomized design was used with four dietary treatments: 0, 2, 4, and 8 kg/t of PSB (54% sodium butyrate). The PSB product (Novation SL 2002, Spain) contains 54% sodium butyrate

Salinity‐Induced Gene Expressions in Pangasius nasutus (Bleeker, 1863)

Aquaculture Research, Volume 2025, Issue 1, 2025.
This study was designed to evaluate the molecular responses of Pangasius nasutus to salinity exposure of varying concentrations. Juveniles of P. nasutus from similar breeding history (average size of 35 ± 0.54 cm and 152 ± 1.82 g) were obtained from a known source in Terengganu.
