Impact of cryopreservation on sterlet, Acipenser ruthenus sperm motility and proteome
Animal Reproduction Science, 2018Fish sperm cryopreservation is a well-established technique allowing for artificial insemination on a commercial scale. The extent of proteome alterations in seminal plasma and sperm due to cryopreservation, however, is not known. This study was conducted to evaluate the effect of cryopreservation on motility variables of sterlet Acipenser ruthenus ...

Role of Ca2+ in the IVM of spermatozoa from the sterlet Acipenser ruthenus
Reproduction, Fertility and Development, 2016The role of Ca2+ in sturgeon sperm maturation and motility was investigated. Sperm from mature male sterlets (Acipenser ruthenus) were collected from the Wolffian duct and testis 24 h after hormone induction. Testicular spermatozoa (TS) were incubated in Wolffian duct seminal fluid (WDSF) for 5 min at 20°C and were designated ‘TS after IVM’ (TSM ...

[Meiotic gynogenesis in the stellate, Russian sturgeon and sterlet].
Ontogenez, 2003Diploid gynogenetic progenies were obtained in the stellate sturgeon Acipenser stellatus, Russian sturgeon A. gueldenstaedtii, and sterlet A. ruthenus by means of insemination of the eggs with UV-irradiated spermatozoa and suppression of the second meiotic division by heat shock.

Larvae of the "European" (ARR) and "Siberian" (ARM) sterlets were fed initially with Tubifex, and further were gradually weaned to dry diet. Additionally two other feeding strategies were tested in ARM: feeding exclusively with dry diet, and sudden weaning from 10 day post-hatch (dph). Survival and yield at 30 dph of

[Organization of nucleotide sequences in the genome of the sterlet Acipenser acipenser].
Molekuliarnaia biologiia, 1980Three fractions of repeated sequences with different thermal stability after reassociation and zero time and single copy fractions as well were isolated from a sterlet (acipenser acipenser) genome. Repeated sequences with different thermal stabilities are organized as homogeneous families not reassociating with one another when being repeatedly ...

The Effect of Ploidy on the Brain Cellular Composition of Sterlet Fish
2023The aim of this thesis was to determine whether the genome size (diploidy vs. triploidy) of a sterlet (Acipenser ruthenus) could affect the number and density of cells housed in their brains. In order to determine this correlation, we quantified the total brain cell counts and neurons using the Isotropic Fractionation. We then compared the values of 2n
