Molecular detection and characterisation of herpesviruses in asymptomatic Russian sturgeon (Acipenser gueldenstaedtii) from European aquaculture

open access: yesJournal of Veterinary Research
In Germany, around 150,000 kg of mostly Siberian sturgeon (Acipenser baerii), were produced in 2021. Sudden mortalities affected negative control Russian sturgeon in experimental infection of several European aquacultured fish species with tilapia lake ...

Nuclear Multi‐Microsatellite Marker Profiling Provides Clues to Molecular Genetic Diversity in Culture‐Based Caspian Beluga Sturgeon (Huso huso) Brood Stocks: Ecological Mirror for Restoration

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
We conducted a study involving 436 individuals of both sexes, collected from eight breeder private farms with diverse breeding histories and generational backgrounds. Through the application of eight microsatellites, we amplified a non‐coding core genomic region in the species, followed by capillary electrophoresis (CE) to provide double confirmation ...

Effectiveness of mass marking of juvenile sterlet (Acipenser ruthenus) with alizarin red S stain on field detection

open access: yesFisheries Management and Ecology, Volume 32, Issue 1, February 2025.
Abstract Sterlet (Acipenser ruthenus), one of the last sturgeons in the Danube basin, is regularly stocked in national and international restoration programs, but the efficacy of stocking has not yet been evaluated. Effectiveness of stocking should involve marking and evaluating growth and survival of juveniles.

Emergence of Aeromonas dhakensis‐linked motile Aeromonas septicemia in Pangasius hypophthalmus biofloc systems in Pakistan

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract This study reports on an outbreak of motile Aeromonas septicemia (MAS) that caused significant mortalities in iridescent shark catfish (Pangasius hypophthalmus) in biofloc systems in the Punjab province of Pakistan. Clinical symptoms observed on the affected fish included anal fin hemorrhaging, mouth area bleeding, skin ulcerations ...

Effects of dietary citric acid, lactic acid, and potassium sorbate mixture on growth performance and intestinal immunological parameters in common carp (Cyprinus carpio) juveniles

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract Acidifiers serve as effective feed additives that enhance fish growth and welfare. This study investigates the effects of a mixture of lactic acid, citric acid, and potassium sorbate (denoted as OA, in a 1:1:1 ratio) on common carp (Cyprinus carpio) for the first time.

A comparison of methods for determining ploidy in white sturgeon (Acipenser transmontanus) [PDF]

open access: yes, 2019
Release of sturgeon with abnormal ploidy into the wild may result in reduced fitness due to lowered fertility in the F2 and subsequent generations. Further, there is evidence that ploidy affects reproductive development and caviar yield.
