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 ...

CD3ε homologues in the chondrostean fish Acipenser ruthenus

Immunogenetics, 2000
CD3epsilon is an essential component of the T-cell receptor (TCR) complex for antigen. We report here molecular cloning and characterization of cDNAs encoding the CD3epsilon homologues in sterlet (Acipenser ruthenus), a representative of primitive chondrostean fishes.

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 ...

The development of the scales of Acipenser ruthenus

Journal of Morphology, 1926
AbstractThe different kinds of scales characteristic of the adult sturgeon are described and the facts of ontogenesis which throw light on the history of these structures are presented.The scales of Acipenser are exclusively mesenchymatous and therefore are not morphologically comparable with the placoid scales of elasmobranchs.
