A Comment on the Siberian, Acipenser baerii, and Russian, Acipenser gueldenstaedtii, Sturgeons
Environmental Biology of Fishes, 2004Contrary to the opinion of Kynard et al. (2002), the Siberian sturgeon, Acipenser baerii, does not belong to the Ponto-Caspian species. It inhabits Siberian rivers and Lake Baikal. Acipenser baerii is a typical potamodromous species and the comparison of the behavior of its embryos and larvae with those of the anadromous Russian sturgeon, Acipenser ...

Aquatic Toxicology, 2023
In the last two decades, much controversy has grown over the use of soybean products in aquafeeds, especially for carnivorous fish like sturgeons. One point of discussion is the effect of soybean phytoestrogens on fish health. There are many aspects of phytoestrogen utilization in aquafeeds, therefore, the aim of this study is to verify if common ...

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.

Dietary copper requirement of juvenile Russian sturgeon Acipenser gueldenstaedtii
Aquaculture, 2016Abstract 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.

Biology of reproduction, 2014
Among sturgeons, the occurrence of individuals with gonads containing both testis and ovary components is considered pathological, and such fish are described as intersex individuals or intersexes. Intersexes are observed in both wild and cultured populations of sturgeon, usually at low frequencies.

Intraspecific genetic polymorphism of Russian sturgeon Acipenser gueldenstaedtii
Russian Journal of Genetics, 2009Three populations (Azov, Caspian, and Black Sea) of Russian sturgeon Acipenser queldenstaedtii were tested for polymorphism at nuclear (RAPD and microsatellites) and mitochondrial (PCR identification of two mito-types) markers. In addition, morphometric analysis of he representatives of Azov population was carried out.

Sexual development in Russian sturgeon (Acipenser gueldenstaedtii) grown in aquaculture
2008The Russian sturgeon (Acipenser gueldenstaedtii) has been introduced into aquaculture in recent years, following the decline of natural populations and the resultant increases in the price of caviar. In nature, males and females of this species mature sexually after 8 to 13 and 10 to 16 years, respectively. Fertilized Russian sturgeon eggs were bred up
