Download or read book Sturgeon Fishes written by Tatiana A. Dettlaff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book People of the Sturgeon written by Kathleen Schmitt Kline and published by Wisconsin Historical Society. This book was released on 2012-07-09 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: People of the Sturgeon tells the poignant story of an ancient fish. Wanton harvest and habitat loss took a heavy toll on these prehistoric creatures until they teetered on the brink of extinction. But, in Wisconsin, lake sturgeon have flourished because of the dedicated work of Department of Natural Resources staff, university researchers and a determined group of spearers known as Sturgeon For Tomorrow. Thanks to these efforts, spearers can still flock by the thousands to frozen Lake Winnebago each winter to take part in a ritual rooted in the traditions of the Menominee and other Wisconsin Indians. A century of sturgeon management on Lake Winnebago has produced the world's largest and healthiest lake sturgeon population. Through a fascinating collection of images, stories and interviews, People of the Sturgeon chronicles the history of this remarkable fish and the cultural traditions it has spawned. The authors introduce a colorful cast of characters with a good fish tale to tell. Color photos by the late Bob Rashid and images from the Wisconsin Historical Society evoke both the magical and the mortal. Weaving together myriad voices and examining the sturgeon's profound cultural impact, the authors reveal how a diverse group of people are now joined together as "people of the sturgeon."

Download or read book The Great Lake Sturgeon written by Nancy A. Auer and published by . This book was released on 2013 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book of its kind to explore this magnificent creature, this collected volume captures many aspects of the remarkable Great Lakes sturgeon, from the mythical to the critically real. Lake sturgeon are sacred to some, impressive to many, and endangered in the Great Lakes. A fish whose ancestry reaches back millions of years and that can live over a century and grow to six feet or more, the Great Lakes lake sturgeon was once considered useless, then overfished nearly to extinction. Though the fish is slowly making a comeback thanks to the awareness-raising efforts of Native Americans, biologists, and sturgeon supporters, it remains to be seen if conservation and stewardship will continue to the degree this remarkable animal deserves. Blending history, biology, folklore, environmental science, and policy, this accessible book seeks to reach a broad audience and tell the story of the Great Lakes lake sturgeon in a manner as diverse as its subject.
Download or read book HEALTHY STURGEON written by Yan Merkulov and published by Applied Sturgeon Agency. This book was released on 2019-11-24 with total page 111 pages. 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 Sturgeon biodiversity and conservation written by Vadim J. Birstein and published by Springer Science & Business Media. This book was released on 1997-05-31 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

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 2005-01-24 with total page 336 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.
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).
Download or read book Recent Advances in Fish Farms written by Faruk Aral and published by BoD – Books on Demand. This book was released on 2011-11-21 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world keeps changing. There are always risks associated with change. To make careful risk assessment it is always needed to re-evaluate the information according to new findings in research. Scientific knowledge is essential in determining the strategy for fish farming. This information should be updated and brought into line with the required conditions of the farm. Therefore, books are one of the indispensable tools for following the results in research and sources to draw information from. The chapters in this book include photos and figures based on scientific literature. Each section is labeled with references for readers to understand, figures, tables and text. Another advantage of the book is the "systematic writing" style of each chapter. There are several existing scientific volumes that focus specially on fish farms. The book consists of twelve distinct chapters. A wide variety of scientists, researchers and other will benefit from this book.
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.

Book excerpt: With coastal fisheries in decline around the world, there is growing concern about how long current sources of seafood can supply world needs. There is an increasing emphasis on restocking and aquaculture-based stock enhancement as a way to rapidly replenish depleted fish stocks and increase fishery landings. This publication contains case studies on the use of sea ranching and marine hatchery enhancement to generate income, re-establish fisheries and conserve aquatic biodiversity, including studies from Norway, Australia, the Pacific Islands, the Caspian Sea with an emphasis on Iran, and Japan.
Download or read book The Siberian Sturgeon Acipenser baerii Brandt 1869 Volume 2 Farming written by Patrick Williot and published by Springer. This book was released on 2018-04-09 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
