Isolation and Cultivation of Sterlet Myoblasts

2023
Over the past 20 years, significant advances have been made in the understanding of cell and tissue culture in the fields of bioengineering, cell biology, and genetics; however, these achievements have largely focused on mammalian systems. In vitro studies on fish cells and tissues have been relatively limited, but the use of fish cell lines as in ...

Optimization of sterlet sperm concentration for cryopreservation

Aquaculture, 2021
Abstract One of the critical points in low temperature storage is the expense of storage capacities. Moreover, sperm concentration in a sample is not only a parameter for effective use of a cryobanks but also a parameter affecting cryopreservation outcomes.

Optimization of sterlet (Acipenser ruthenus) egg incubation

Animal Reproduction Science, 2020
Sterlet Acipenser ruthenus was used to assess egg and embryo development when incubated at 17 °C in Petri dishes placed in a hatchery tank (300 L recirculating dechlorinated water) with incubation occurring in a static tabletop system in an air-conditioned laboratory, or in a 700 L Q-cell incubator.

Subdivisions of the olfactory system in the sterlet Acipenser ruthenus

Neuroscience Letters, 1997
Subdivisions of the olfactory system of the sterlet Acipenser ruthenus were investigated by means of horseradish peroxidase (HRP) injections into the nose, and by soybean agglutinin binding studies. With both methods primary olfactory fibers were labeled which projected to the ventral part of the glomerular layer of the olfactory bulb.

In vitro sperm maturation in sterlet, Acipenser ruthenus

Reproductive Biology, 2014
The aim of the study was to examine sperm maturation in sturgeon and to establish the localization of the maturation. We demonstrated that sperm maturation occurs in sturgeon outside the testes via dilution of sperm by urine. The process involves the participation of high molecular weight (>10kDa) substances and calcium ions.

First evidence of autotriploidization in sterlet (Acipenser ruthenus)

Journal of Applied Genetics, 2013
Polyploidization has played an important role in vertebrate evolution. Acipenseridae bring clear examples of polyploidy ancestry and, also, polyploidization seems to be an ongoing process in these fishes. In the present study, the genetic origin of six triploid specimens morphologically determined as Acipenser ruthenus from commercial aquaculture was ...

Review of sterlet (Acipenser ruthenus L. 1758) (Actinopterygii: Acipenseridae) feeding  habits in the River Danube, 1694–852 river km

Journal of Natural History, 2015
The aim of this work is to present the variation in the sterlet's (Acipenser ruthenus L. 1758) diet along the course of the River Danube, from 1694 to 852 river km. The diet of sterlet mostly comprised 12 bottom fauna taxa. Sterlet in the Danube

Complete mitochondrial genome of sterlet (Acipenser ruthenus)

Mitochondrial DNA, 2013
The complete mitochondrial genome of sterlet (Acipenser ruthenus) was determined in this study. The mitogenome is 16,790 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 2 non-coding regions (the control region and the putative origin of the light strand replication) with a typical vertebrate ...

Meiotic Gynogenesis in the Stellate and Russian Sturgeons and Sterlet

Russian Journal of Developmental Biology, 2003
Diploid 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.

The antioxidant system of sterlet seminal fluid in testes and Wolffian ducts

Fish Physiology and Biochemistry, 2014
Oxidative stress is a possible source of spermatozoa function deterioration. Seminal fluid (SF) protects spermatozoa against reactive oxygen species (ROS) attack during development in testes and transit through the reproductive tract. Spermatozoa curvilinear velocity and percent of motile cells as well as changes in thiobarbituric acid-reactive ...
