Motility analysis and energetics of the Siberian sturgeon Acipenser baerii spermatozoa
Journal of Applied Ichthyology, 199990% des spermatozoïdes sont activés en quelques secondes après dilution puis réduiront régulièrement leur activité juqu'à 5-10% au bout de 2mn. Durant la même période, le battement des spermatozoïdes baissera de 50Hz à 25-40Hz après 40sec. Le mouvement des flagelles, d'abord distribué uniformémént sur toute la longueur, disparaîtra de l'extrémité chez ...

Sperm and Spermatozoa Characteristics in the Siberian Sturgeon
2017Sperm and spermatozoa in Siberian sturgeon are very interesting and specific from several points of view. Siberian sturgeon usually produces high volume of semen with relatively low sperm and protein concentration, which is partially explained by the atypical testicular morphology where spermatozoa are mixed with urine during passage through the ...

Sex Determination and Differentiation of the Siberian Sturgeon
2017This is a synthesis of the published information on sex determination and differentiation in sturgeons with special emphasis in Siberian sturgeon Acipenser baerii. The sex-determination system has been poorly studied in sturgeons and paddlefishes. Among 27 species of Acipenseriformes, the WZ-female model has been proposed in five species and one hybrid

Gene delivery into Siberian sturgeon cell lines by commercial transfection reagents
In Vitro Cellular & Developmental Biology - Animal, 2019The optimal transfection conditions for efficient transgene delivery into a specific cell type should be empirically determined, particularly in cases involving unusual cell types. We compared the conditions for effective introduction of transgenes into Siberian sturgeon (Acipenser baerii) cell lines by evaluating the cytotoxicity and transfection ...

Cannulation in the Cultured Siberian Sturgeon, Acipenser baerii Brandt
2017The chapter deals with a detailed description on how to equip a sturgeon with an intra-aortic cannula. In a first section, the advantages of such a procedure are recalled. Later on, a brief overview cannula in sturgeon is given. Further, the list of material and the chronology of process are provided.

Echography for Siberian Sturgeon (Acipenser baerii) Brood Stock Management
2017The lack of external sexual dimorphism in sturgeons, including Siberian sturgeon, had been hampering the brood stock establishment and caviar production for a long time. The development of noninvasive express techniques of echography diagnostics of Siberian sturgeon has allowed to optimize sex structure of the sturgeon brood stocks, and to increase ...

Controlled Reproduction of Farmed Siberian Sturgeon Acipenser baerii Brandt
2017The present chapter is a synthesis of the available data related to the management of the reproduction of the Siberian sturgeon under farmed conditions. Some reproduction-related biological characteristics are briefly quoted. Preselection of potential brood fish is related in detail as well as pre-spawning holding regime with a focus on water ...

What Makes the Difference Between the Siberian Sturgeon and the Ponto-Caspian Sturgeon Species?
2017Adaptive features of the Siberian sturgeon connected with species structure (adaptive radiation), population structure, ecology, physiology, reproduction and development in comparison with phylogenetically closely Ponto-Caspian sturgeon related species were analyzed. The adaptive radiation of freshwater Siberian sturgeon unlike anadromous Ponto-Caspian

Behaviour of Early Life Stages in the Siberian Sturgeon
2017In this chapter, field data and laboratory studies on the behaviour and development of Siberian sturgeon at early-life intervals have been reviewed and the available information assessed under two different points of view, the biological/ecological approach and the aquaculture one.
