This book is the first comprehensive description of development of the Acipenserid fish published in the English language. It con tains the results of more than 40 years of studies by the authors and their colleagues. My own life in science has been intimately related both with the authors and the fish, which are the subject of this book. Therefore, it gives me a great pleasure to present to the English reader an expanded version of the book. Those interested in the history of biology must be well aware of the fact that genetics in the USSR was practically demolished by Lysenko at the session of the Lenin All-Union Academy of Agricultural Sciences in 1948. However, it is much less well known that other fundamental branches of biology were also persecuted at that time, experimental embryology (developmental mechanics) among them. As a result, many embryologists, in cluding the authors of this book, were forced to turn to more ap plied problems, this being the only way to continue research. They had to abandon amphibians and concentrate their efforts on sturgeon.

"Healthy sturgeon" - a practical guide to the diagnosis and treatment of sturgeon diseases in aquaculture. How did the idea of this book come about? Full-cycle breeding of sturgeon in fresh water is a relatively young direction of aquaculture, compared, for example, with the cultivation in artificial conditions of species such as carp or trout. The main incentive for the rapid large-scale development of sturgeon breeding was a catastrophic reduction in the number of sturgeons in nature and the introduction, in this regard, of a ban on their fishing. Within a short time, thousands of fish farms appeared around the world, some of which were previously cultivated by other species, while others were built specifically for sturgeon. The available knowledge about sturgeons characterized them as very resistant to various fish diseases. However, in practice, fish farmers from both old and newly created farms are faced with the fact that under artificial conditions all groups of sturgeon (from young to mature fish) are significantly susceptible to various diseases. There were frequent cases when in certain periods the death of sturgeon juveniles reached 90%. One of the main reasons for this is that radical changes in lifestyle, expressed in the exclusion of the sea period and constant keeping in fresh water, have had a negative impact on sturgeon resistance to diseases that have not previously been noted at these fish. This is especially true for bacterial diseases that cause the most damage on sturgeon farms. Many fish farmers were not ready for this. As practice shows, if fishery specialists had taken timely measures to identify diseases in the initial stages, then, in most cases, it would be possible to prevent the mass death of fish and avoid serious losses. Therefore, working on this book, we have tried to fully help fish farmers in solving the main problems: timely diagnosis of diseases, the choice of emergency measures to prevent the development and further spread of the disease and, most importantly, the creation of conditions that prevent the emergence of diseases of fish on the sturgeon farm. The diagnostic and laboratory research methods described in this manual are focused specifically on the capabilities of fisheries laboratories, which are equipped mainly with optical equipment and rapid analysis tools. A detailed description of the external manifestations and clinical signs that in a fish farm will help to establish the onset of the disease in a timely manner was a priority task that the authors of this book tried to solve. For a better perception, all the diseases described in the book are illustrated by a large number (more than two hundred) of original photographs, diagrams and drawings. For ease of use of the book, the materials are grouped into three sections: The first section is devoted to general information about diseases, the principles of their diagnosis and ichthyopathological examination. Also, the section provides information about the features of the anatomy of sturgeon, in relation to the issues of ichthyopathology. The second section contains descriptions of infectious and non-infectious diseases of sturgeon, indicating the causes of their occurrence, risk factors and methods of treatment. The third section describes the general principles and methods of treatment of fish, the characteristics of some of the most commonly used drugs. The materials of the manual are adapted for a wide range of readers, including those studying fish farming and fish diseases on their own.

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

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.

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.
