Changes in immune parameters (lysozyme, IgM, C3) in early life stages and broodstock of Siberian sturgeon, Acipenser baerii

open access: yesArchives of Polish Fisheries, 2018
In the present study, lysozyme, immunoglobulin M (IgM), and complement component 3 (C3) were measured in unfertilized and fertilized eggs, two week post fertilization (WPF) larvae and 1, 2, 4, 6, and 12 month post fertilization (MPF) juveniles and the ...

It’s raining sturgeons: a likely occurrence of avian predation or scavenging of Atlantic Sturgeon (Acipenser oxyrinchus Mitchell, 1815) [PDF]

open access: yes, 2021
Predation on the federally-endangered Atlantic Sturgeon (Acipenser oxyrinchus), and sturgeons generally is understudied. Most predation is presumed to occur on eggs and larvae, and bethe result of interactions with other aquatic organisms, primarily ...

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 ...

Unlocking the Secrets of Sturgeon Ecology: Lessons From Conservation Efforts in Northern Italy

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.
ABSTRACT This study aimed to investigate the ecology of the Adriatic sturgeon (Acipenser naccarii) and Beluga sturgeon (Huso huso) in the Po basin in northern Italy, where both species have faced significant population declines. Using data collected from three LIFE projects, we investigated movement behaviour and habitat selection of the species ...
