Ultrasound diagnostic for sturgeon

Practical guideline //SECOND EDITION//

By: Yan Merkulov,Ivan Markov

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 provides basic principles of ultrasound diagnostic and recommendations for the sturgeon ultrasound diagnostic equipment and workplace arrangements. There is a detailed description of ultrasound diagnostic procedure for identification of sex and maturity stage of sturgeon gonads. There is also a detailed instruction on ultrasound images analysis and description of specific diagnostic features. Annual sexual cycles with various inter-spawn intervals were for the first time analysed specifying the duration of each maturity stage in heat-reserve units. The principles of controlling linear and generative growth of sturgeons contained in replacement and breeding stocks of sturgeon farms had been defined. The Atlas contains more than a hundred illustrations, provided with detailed descriptions and notes which allow even a novice fish farmer to independently learn ultrasound diagnostic of sex and maturity stage of sturgeon gonads. The book is addressed to specialists and chief managers of sturgeon farms, the farmers involved in sturgeon breeding, scientists and students.

HEALTHY STURGEON

STURGEON DISEASE AND TREATMENT ILLUSTRATED GUIDELINES

By: Yan Merkulov,Ivan Markov

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.

Diachronic Interpretation of the Nostratic Macrofamily

A Comparative Study of Altaic, Afro-Asiatic, Dravidian, Eskimo-Aleut, Indo-European, Kartvelian, and Uralic Proto-Languages

By: Yan Kapranov,Bożena Iwanowska,Bolesław Cieślik

This monograph presents a groundbreaking exploration into the Nostratic macrofamily, a concept that proposes a common ancestral language for several of the world's foremost language families. The study delves deep into the roots of Altaic, Afro-Asiatic, Dravidian, Eskimo-Aleut, Indo-European, Kartvelian, and Uralic languages, offering a unique perspective on their interconnections and evolutionary paths. The authors examine five pivotal Nostratic etymons from the Swadesh index to illustrate the shared cognitive frameworks of these diverse linguistic groups. This research challenges conventional perspectives on language evolution and introduces new methodologies in cognitive macro-comparative studies. Key to the work is the hypothesis of divergent-convergent and convergent-divergent evolutionary patterns stemming from a common Nostratic origin. Beyond linguistics, this study offers insights into human cognitive development, language formation, and change mechanisms.
