Transferrin Identification in Sterlet (Acipenser ruthenus) Reproductive System [PDF]

Animals, 2019
Transferrins are a superfamily of iron-binding proteins and are recognized as multifunctional proteins. In the present study, transcriptomic and proteomic methods were used to identify transferrins in the reproductive organs and sperm of out-of-spawning ...

Efficient Gene Transfer and Gene Editing in Sterlet (Acipenser ruthenus) [PDF]

Frontiers in Genetics, 2018
The sturgeon (Acipenseriformes) is an important farmed species because of its economical value. However, neither gene transfer nor gene editing techniques have been established in sturgeon for molecular breeding and gene functional study until now.

Multi‐Marker Mitochondrial Analysis Reveals Genetic Diversity and Phylogenetic Relationships of Black Sea Sturgeons (Acipenseridae) [PDF]

Ecology and Evolution
Sturgeons represent a critical taxon for conservation due to their complex genetic structure and vulnerability to anthropogenic pressures, including poaching, overfishing, and habitat loss. This study provides a multi‐level mitochondrial characterization

Identification and characterization of hybrids of Acipenser ruthenus and Acipenser baerii (Actinopterygii, Acipenseriformes) from the Irtysh River [PDF]

Acta Biologica Sibirica, 2021
Two sturgeon species, Acipenser ruthenus (Linnaeus, 1758) and Acipenser baerii (Brandt, 1869), inhabit the Irtysh basin. In 2018, we received some “atypical” specimens of sturgeon, which were similar to A. ruthenus but had a number of pronounced external

Fluorescent emission profiles reveal interspecific differences in three Danube River Basin sturgeon species [PDF]

Scientific Reports
Biofluorescence is widespread among marine teleosts but has not been reported in sturgeons (Acipenseridae). This exploratory study investigates interspecific differences in fluorescent emission profiles among three Danube River Basin sturgeon species ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs. [PDF]

J Anat
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Investigation of ice particle formation points during fish sperm cryopreservation [PDF]

E3S Web of Conferences, 2023
This study was conducted in order to investigate of the points of formation of ice particles during cooling of fish sperm. The object of the study was spermatozoa of the Russian sturgeon (Acipenser gueldenstaedtii Brandt, 1833), hybrid Acipenser ruthenus

Examination of white blood cell indicators for three different ploidy level sturgeon species reared in an indoor recirculation aquaculture system for one year

Veterinární Medicína, 2022
Functional diploid Acipenser ruthenus, functional tetraploid Acipenser gueldenstaedtii and functional hexaploid Acipenser brevirostrum juveniles were sampled monthly for one year, and the white blood cell indicators were determined.
