ASSESSMENT OF THE GENETIC DIVERSITY OF THE RUSSIAN STURGEON BROOD STOCK OF THE DONSKOY STURGEON PLANT BY MICROSATELLITE NUCLEAR MARKERS

II МЕЖДУНАРОДНОЙ НАУЧНО-ПРАКТИЧЕСКОЙ КОНФЕРЕНЦИИ «РАЗВИТИЕ И СОВРЕМЕННЫЕ ПРОБЛЕМЫ АКВАКУЛЬТУРЫ» (КОНФЕРЕНЦИЯ «АКВАКУЛЬТУРА 2022»), 2022
The article presents a study of the genetic diversity of the Russian sturgeon (Acipenser gueldenstaedtii) of the brood stock (RMS) of the Donskoy sturgeon hatchery (DOZ) using the analysis of microsatellite nuclear markers. In the course of the study, a general decrease in the heterozygosity of the population for four of the five loci studied was ...

Electrolyte composition of embryo and larva of the Russian sturgeon in the process of development

Comparative Biochemistry and Physiology Part A: Physiology, 1976
Abstract 1. 1. The dry solids of eggs and larvae are gradually decreased, the most pronounced mass reduction being observed in larvae. In the process of egg development the water content is significantly increased after fertilization and the transition to larva state. 2. 2. In the first two days after fertilization a loss of a minor amount of

The complete mitochondrial genome of Russian sturgeon ( Acipenser gueldenstaedti )

Mitochondrial DNA Part A, 2014
Russian sturgeon (Acipenser gueldenstaedti) belongs to the Acipenseriformes Acipenseridae. In this study, we sequenced and characterized the complete mitochondrial genome of A. gueldenstaedti from National Sturgeon Hatchery, Chinese Academy of Fishery Sciences.

Isolation and characterization of insulin in Russian sturgeon (Acipenser guldenstaedti)

The Journal of Peptide Research, 1998
Insulin was isolated from the pancreas of Chondrostean fish, the Russian sturgeon, Acipenser guldenstaedti, by acid‐ethanol extraction followed by ion‐exchange and reverse‐phase high‐performance liquid chromatographies. The amino acid sequence determined by automated Edman degradation is as follows: A‐chain (21‐amino‐acid peptide), H‐Gly‐Ile‐Val‐Glu ...

Dispermic androgenesis in sturgeons with the use of cryopreserved sperm: Production of androgenetic siberian sturgeon and androgenetic hybrids between Siberian and Russian sturgeons

Russian Journal of Developmental Biology, 2011
Dispermic androgenesis was used to produce, for the first time, an androgenetic progeny of the Siberian sturgeon (Acipenser baerii) and the androgenetic nucleo-cytoplasmic hybrids (Siberian sturgeon, A. baerii × Russian sturgeon, A. gueldenstaedtii) using cryopreserved sperm. Microsatellite DNA analysis confirmed exclusively paternal inheritance in the

Regulation of spermatozoa motility in response to cations in Russian sturgeon Acipenser gueldenstaedtii

Theriogenology, 2012
The aim of this study was to investigate the response of Russian sturgeon (Acipenser gueldenstaedtii) sperm to external cations (Na(+), K(+), Ca(2+), and Mg(2+)) and their susceptibility on the induction of motility and swimming behavior. An in vitro spermatozoa motility assay was used by a computer-aided Motion-Analysis system.

Features of osmotic and ionic regulations in russian sturgeon (Acipenser güldenstädti brandt)

Comparative Biochemistry and Physiology Part A: Physiology, 1985
The osmolality of blood serum of one group of Russian sturgeon fished out in Southern Caspian Sea was the same as their habitat, the other group of sturgeons had a serum osmolality several per cent lower than that of sea-water in this part of the Caspian Sea. Ion concentrations in blood serum in sturgens were similar in fresh water and the Caspian Sea.

Quality assessment of young of the hybrids “Lensky sturgeon × Russian sturgeon” and “bester” grown in a circulated water supply unit

Rybovodstvo i rybnoe hozjajstvo (Fish Breeding and Fisheries), 2022
The actual direction of modern aquaculture is the optimization of fish breeding processes by monitoring and managing environmental parameters and feeding regimes, reducing the influence of seasonality on technological processes in order to increase the yield of marketable products per unit area.

[Meiotic gynogenesis in the stellate, Russian sturgeon and sterlet].

Ontogenez, 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.

Dietary copper requirement of juvenile Russian sturgeon Acipenser gueldenstaedtii

Aquaculture, 2016
Abstract To quantify the dietary copper (Cu) requirement of Russian sturgeon Acipenser gueldenstaedtii, copper sulfate (CuSO4·5H2O) was added into the basal semi-purified diet at seven levels 0, 1, 2, 4, 6, 8 and 16 mg Cu kg− 1 diet yielding the actual dietary values of 0.3, 1.5, 2.4, 4.4, 6.2, 8.3 and 16.1 mg Cu kg− 1 diet, respectively.
