The biology of the Siberian sturgeon, Acipenser baerii Brandt 1869,
has become a very attractive subject of investigation for
biologists since the 1980s. This volume 1 is part of a two-volume
set devoted to the species, the second of which focuses on farming.
The present volume is divided into three parts: Biology and
ecology, Biology and physiology of reproduction, and Ecophysiology,
i.e. adaptation to the environment. The first part addresses a
broad range of topics, such as: the ecology, including a new
approach to species-specificity, a new insight on the
mineralization of vertebral elements, two approaches to sex
determination, transposable elements in the gonads, early ontogeny,
olfaction and gustation, nutrition and swimming. The second part
includes neurochemical and anatomical descriptions of the central
nervous system and an updated version of the oogenesis, the
characteristics of both sperm and spermatozoa, and a synthesis on
gonadal steroids (synthesis, plasmatic levels and biological
activities). In turn, the third part reveals how the physiology of
the species changes depending on environmental factors such as
oxygen, ammonia, and nitrite. Some fundamental consequences of
ammonia are developed (sublethal and lethal levels, effects on gill
epithelium and haematology, acid-base balance, on AA and adenyl
nucleotides levels in plasma, brain and muscle tissue). In
addition, the book includes two methodological chapters dealing
with fish dorsal aortic cannulation and respiration physiology.
