Effects of Different Carbon Sources on Growth and Some Innate Immune Responses of Russian Sturgeon (Acipenser gueldenstaedtii) in Biofloc Systems

Marine Science and Technology Bulletin, 2023
The Russian sturgeon (Acipenser gueldenstaedtii) species is in high demand owing to its valuable caviar. Therefore, it is in danger of extinction. Since the Russian sturgeon reaches sexual maturity late in its life cycle, this species has a high economic

Gill Adaptation of the Hong Kong Catfish (Clarias fuscus) to Chronic Heat Stress: Tissue Remodeling, Enhanced Antioxidant Defense and Immune Metabolism Regulation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Continuous high‐temperature culture altered the structure of gill tissue, enhanced antioxidant capacity, and promoted apoptosis C. fuscus. In response, the organism mitigates extensive apoptosis and strengthens its repair capacity by regulating immune and energy metabolism pathways.

Cross‐species conservation of a transposase‐linked element enables genetic sexing of commercial populations of Russian sturgeon (Acipenser gueldenstaedtii)

Animal Genetics, 2022
Summary All‐female culture of sturgeon is essential for efficient caviar production. However, Russian sturgeon (Acipenser gueldenstaedtii) does not exhibit external sexual dimorphism, and therefore, commercial farms apply gonadal endoscopy or ultrasound ...

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.
