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 Biology and Conservation of the European Sturgeon Acipenser sturio L 1758 written by Patrick WILLIOT and published by Springer Science & Business Media. 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 Conservation of the Biological Diversity as a Prerequisite for Sustainable Development in the Black Sea Region written by V. Kotlyakov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of reports presented at the International NATO Advanced Research Workshop Conservation of the Biological Diversity as a Prerequisite for Sustainaible Development of the Black Sea Region. The seminar was held at Batumi - Kobuleti, Georgia, on the Black Sea during October 5 -12, 1996 with participants from the countries of the Black Sea Region -Georgia, Russia, the Ukraine, Turkey, Bulgaria, Romania, as well as Germany, Italy and the United States of America. The Black Sea Region is an essential and unique part of southern Europe because of its geographical, cultural and historical features. It is the cradle of European civilisation, together with Greece and Rome. For centuries it neighboured onto and interacted with the cultures of the northern and southern Mediterranean, the Christian and Moslim worlds, and was the route of conquerors and migrations of whole nations. Here are closely interwoven the cultures and customs of nations, economic and trade relations, the history of wars and civilised relations of neighbouring countries.
Download or read book Ecological Sustainability of Fish Resources of Inland Waters of the Western Balkans written by Vladica Simić and published by Springer Nature. This book was released on 2023-12-31 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed evaluation of the hydro-ecological characteristics of the Western Balkans, an area characterized by still preserved inland waters and fish resources important for the European continent, as well as the biodiversity of inland waters important for the planet Earth. Freshwater ecosystems cover only 1% of the Earth's surface; however, they are a habitat for about 40% of fish species. At the same time, inland fisheries make less than 12% of the world's global fish catch, with 43% coming from low-income and food-deficient countries (Africa, South America, Southeast Asia). In Europe, the Western Balkans have significant fishing waters and fish resources, including the Middle Danube drainage (Sava, Drina, Velika Morava river systems), large ancient lakes (Skadar/Shkodra, Ohrid, Prespa, Dojran), and the Adriatic basin characterized by endemic and commercially important species. However, in contrast to the high fishing potential in a significant part of the Western Balkans, diverse and specific political, economic, and social factors largely had a negative impact on the state of fish resources. This volume is multidisciplinary and provides a sound knowledge base for scientific and practical fisheries. In addition, it may be a valuable guide for managers and conservationists worldwide to adapt methods and procedures for the ecological sustainability of fish resources under specific local, natural, and socio-economic conditions. Finally, the content is a good reference for natural sciences and agriculture students studying fish, fish resources, and fisheries sciences. It would improve their knowledge and perspectives on the challenges of sustainable use and conservation of inland water resources.
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.
Download or read book The Illegal Wildlife Trade written by Daan P. van Uhm and published by Springer. This book was released on 2016-11-15 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the author examines the illegal wildlife trade from multiple perspectives: the historical context, the impact on the environment, the scope of the problem internationally, the sociocultural demand for illegal products, the legal efforts to combat it, and several case studies from inside the trade. The illegal wildlife trade has become a global criminal enterprise, following in the footsteps of drugs and weapons. Beyond the environmental impact, financial profits from the illegal wildlife trade often fund organized crime groups and violent gangs that threaten public safety and security in myriad ways. This innovative volume covers several key questions surrounding the wildlife trade: why is there a demand for illegal wildlife products, which actors are involved in the trade, how is the business organized, and what are the harmful consequences. The author performed ethnographic fieldwork in three key markets: Russia, Morocco, and China, and has constructed a detailed picture of how the wildlife trade operates in these areas. Conversations with informants directly involved in the illegal business ensure unique insights into this lively black market. In the course of his journey the author follows the route of the illegal wildlife trade from poor poaching areas to rich business districts where corrupt officials, legally registered companies, wildlife farms and sophisticated criminal organizations all have a share. A fascinating look inside the world of poachers, smugglers and traders.

This book was released on 2021-01-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review presents summary information on 45 river and great lake basins of the world, which support inland fisheries. The information presented is drawn from published information in peer-reviewed journals as well as grey literature. Each basin summary is presented in a common format, covering the description of the fishery, estimates of catch and numbers of people engaged in the fishery, important biodiversity features and threats to the fishery. An analysis of the replacement costs of inland fish of the basin is also presented. This is expressed in terms of the water, land and greenhouse gas footprint that would arise if the inland fish that are currently produced had to be replaced with other forms of food (such as aquaculture fish, livestock or field crops).

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.
