Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Biology Conservation and Sustainable Development of Sturgeons written by Ramón Carmona and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

This book was released on 2011-08-24 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen’s organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.
Download or read book Rescue of Sturgeon Species in the Ural River Basin written by Viktor Lagutov and published by Springer Science & Business Media. This book was released on 2008-10-22 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: While almost every aspect of society-nature interactions can be treated as an environmental security issue, the threats to human societies originating from inadequate freshwater management constitute one of the most wi- spread and pressing problems. For thousands of years rivers and river valleys have been the cradle of human civilizations. Rivers have provided not only food and freshwater, but also shelter and means of transportation, and they are still an essential component in every national and regional economy. In turn, growing needs of human societies, accompanied by growing abilities, have caused significant river alterations and ecosystem changes that have resulted in river contamination, biodiversity loss and general riverine ecosystem degradation. The extinction of sturgeon species is one of the most eloquent examples of the negative and irreversible influence of human society on river e- systems. The sturgeon, sometimes called the “living fossil” or living “dinosaur” of the fish world, is known to have lived since the time of the dinosaurs, for at least 250 million years, and is currently on the verge of extinction solely due to anthropogenic impacts.
Download or read book The Siberian Sturgeon Acipenser baerii Brandt 1869 Volume 1 Biology written by Patrick Williot and published by Springer. This book was released on 2018-04-06 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
