Morphogenesis of the eye of Siberian sturgeon

Journal of Fish Biology, 2001
The most relevant changes in Acipenser baeri eye organization were detected between hatching and 5 days post hatch. At this age, the eye had an anterior chamber, lens, iris, choroid gland, scleral cartilage, cornea and a vitreous chamber lined by the retina (with two photoreceptors: rods and single cones).

Advances in the larval rearing of Siberian sturgeon

Journal of Fish Biology, 2002
Since first large‐scale attempts to culture sturgeon from the larval stage were carried out in the former U.S.S.R. at the end of the nineteenth century, rearing technology has advanced considerably during the last 20 years and noticeable improvements in incubation and larval rearing techniques have been implemented in normal hatchery procedures ...

Hybrids of the Siberian Sturgeon

2017
It is known that all sturgeon species when crossed (both interspecific and intergeneric crossings) allow to produce viable offspring, whereupon breeding of various hybrids of Siberian sturgeon is of practical importance for commercial or caviar sturgeon farming in various climatic and technological conditions.

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

The Blood Indicators of Siberian Sturgeon Welfare

2017
Animal welfare science is expanding rapidly. The use of physiological indicators is one of the most investigated ways in which to evaluate welfare. Blood samples are minimally invasive; they enable successive sampling of the same individuals and provide access to a large range of indicators from numerous physiological functions.

Siberian Sturgeon Sperm Cryoconservation

2017
Sperm cryopreservation can potentially be used as a management tool for better organisation of spawning and improvements of breeding programs, providing a security strategy against decline in natural populations and incorporating of genes from wild fish into hatchery populations.

Swimming Characteristics of the Siberian Sturgeon

2017
The Siberian sturgeon, Acipenser baerii Brandt, widely distributed throughout all major rivers in Siberia, inhabits the largest range compared to other sturgeon species. Nowadays, the Siberian sturgeon is the main species for sturgeon aquaculture in several countries.

Weaning in Siberian Sturgeon Larvae

2017
In this chapter we have revised the available information regarding feeding practices with Siberian sturgeon larvae from the onset of exogenous feeding to the early juvenile stage, data gathered from published studies and compared and/or complemented with current practices from French hatcheries.

Early Ontogeny in the Siberian Sturgeon

2017
This chapter is a synthesis of published information describing the development of Siberian sturgeon during the embryonic (from fertilization to hatching), prelarval (from hatching to the onset of exogenous feeding) and larval (from first feeding to the juvenile stage) periods.

Reproductive Cycles in Sturgeons with a Special Focus on the Farmed Siberian Sturgeon

2017
The chapter reports the published data on biological cycles and/or puberty in sturgeons for both wild and farmed brood stocks. There are three main lines to document these data, the analysis of large-scale sampling or landings, the analysis of sampling with previously tagged fish and the echography which has a remarkable efficacy.
