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: chara...
"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 ...
The digest contains descriptions of 21 patents related to the processing and salting of sturgeon caviar (mainly ovulated, i.e. obtained in vivo), registered at different times in Russia. The materials of the digest are divided into four chapters. The first section contains descriptions of the methods for pretreating ovulated eggs (without salting), including two methods of preparing the so-called raw caviar, intended for long-term storage, followed by transfer to the caviar factory. The second section is devoted to the description of the methods for salting ovulated caviar with the preparation of granular or pressed caviar, both without the use of preserving agent or with the use of various preserve substance. The third section provides methods for processing non-ovulated caviar, and the fourth section contains a description of some preserving agents and how to use them. The materials of the digest can be used both for organizing independent processing of caviar by novice sturgeon farms, and for optimizing the technological process at existing caviar production facilities.
The second edition of the manual on ultrasound diagnostics of the sturgeon reproductive system contains several significant additions based both on the appearance of new equipment for ultrasound diagnostics and on the results of recent studies of the authors. The new edition describes in detail the features of various types of ultrasonic sensors, including previously not used for sturgeon diagnostics. At the request of readers of the first edition, the features of the analysis of echograms obtained using a convex sensor are considered. The section describing the diagnosis of pathologies of the reproductive system of fish, including hermaphroditism, has been substantially expanded. The guide ...

In this single work to cover the use of plasma as nanofabrication tool in sufficient depth internationally renowned authors with much experience in this important method of nanofabrication look at reactive plasma as a nanofabrication tool, plasma production and development of plasma sources, as well as such applications as carbon-based nanostructures, low-dimensional quantum confinement structures and hydroxyapatite bioceramics. Written principally for solid state physicists and chemists, materials scientists, and plasma physicists, the book concludes with the outlook for such applications.
This book delivers a comprehensive overview of the characteristics of several types of materials that are widely used in the current era of supercapacitors; namely, architectured carbon materials, transition metal oxides and conducting polymers. It provides readers with a complete introduction to the fundamentals of supercapacitors, including the development of new electrolytes and electrodes, while highlighting the advantages, challenges, applications and future of these materials. This book is part of the Handbook of Nanocomposite Supercapacitor Materials. Supercapacitors have emerged as promising devices for electrochemical energy storage, playing an important role in energy harvesting fo...
