Amygdalin Mitigates Benzo[a]pyrene‐Induced Stress and Hepatic Dysfunction in Stellate Sturgeon Fry ( Acipenser stellatus ): Insights Into Immune and Metabolic Modulation

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
This study evaluated the protective role of amygdalin against benzo[a]pyrene (BaP) toxicity in stellate sturgeon fry ( Acipenser stellatus ). Fish were pre‐exposed to amygdalin (5 g/kg) and subsequently challenged with sublethal BaP concentrations ...

Results of growing stellate sturgeon (Acipenser stellatus) obtained using cryopreserved sperm

Fisheries
Artificial reproduction of stellate in the Volga-Caspian fishery subregion is currently carried out by only one fish hatchery. At present, the volume of artificial reproduction has significantly decreased from 0 to 0.25 million individuals. The aim of the work was to assess the growing conditions, fish-breeding, biological and physiological ...

Biological responses of stellate sturgeon fingerlings (Acipenser stellatus) immersed in HSP inducer to salinity changes.

Marine Environmental Research, 2023
Changes in salinity is a stressful and energy-consuming process in fish which give rise to mortalities, especially in fish fingerlings that are more sensitive during the early stages of their life. In the present study, the effects of three salinities, 3‰

Biochemical Characterization of Hemoglobins from Caspian Sea Sturgeons (Acipenser persicus and Acipenser stellatus)

Cell Biochemistry and Biophysics, 2011
Hemoglobin (Hb) variability is a commonly used index of phylogenetic differentiation and molecular adaptation in fish enabling them to adapt to different ecological conditions. In this study, the characteristics of Hbs from two Sturgeon species of the Southern Caspian Sea Basin were investigated. After extraction and separation of hemoglobin from whole

Ultrastructure of the heart of the sturgeon Acipenser stellatus (Chondrostei)

Cell and Tissue Research, 1979
The ultrastructure of atrial and ventricular myocardial cells from Acipenser stellatus is described. The cells of the atrium are more loosely connected than those of the ventricle. Cell contact is by simple intercalated discs and by desmosomes. The cells are flattened, with peripheral myofibrils and a central region of mitochondria and the nucleus. The
