The Siberian sturgeon, Acipenser baerii Brandt 1869 is the most
widely farmed sturgeon species. Continuing from Volume 1, which
focuses on the biology of the species, the present Volume 2 in turn
examines farming aspects. It is divided into six parts, the first
of which deals with reproduction and early ontogenesis, i.e.
reproductive cycles, controlled reproduction, sperm
cryoconservation, and weaning of larvae. The second covers the
growing phase with a focus on food and feeding (management, fish
meal replacement, potential endocrine disruptions, usefulness of
prebiotics and immunostimulants, and nitrogen excretion).
Production-related data are the focus of the third part and
include: characteristics (countries, structures of production,
evolution in production, economic features) of the gross production
of the species (meat and caviar) worldwide, a method for assessing
the quality of caviars, off-flavors management, and an example of
production of fingerlings for restocking. Part four addresses
selected long-term management issues: genetic variability of brood
stocks, genome manipulation and sex control, and the advantages of
hybrids. The next three chapters constitute the fifth part, which
is devoted to health status (immunology and welfare). In closing,
the absence of ecological risks of introducing the species in
non-native waters is shown using two long-term documented examples
(Russia and France). Three methodological chapters round out the
volume, covering: in vitro incubation of ovarian follicles, a
richly illustrated library of echographies and photos, and a
detailed presentation of oxygen demand studies.
