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 Good practices guidelines for data collection systems to support sustainable inland and recreational fisheries in the Western Balkans region written by Visser, T.A.M, Valbo-Jorgensen, J., Chomo, V. and published by Food & Agriculture Org.. This book was released on 2021-02-26 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines illustrate recommendations for good practices on data collection in Eastern European inland fisheries, and in particular the Western Balkan region, based on the methodologies and approaches used in countries throughout Europe and from FAO experience of inland fisheries in other regions. They provide guidance on the options available to inland fishery managers based on particular circumstances i.e. commercial fishing or recreational use, and they are especially relevant for assisting the economies-in transition in Europe, Caucasus and Central Asia. These guidelines are not an overarching work on inland fisheries management, nor do they provide advice on the environmental aspects or competing uses of inland water bodies. They focus on issues of data collection to support fishery managers whether they be government agencies, fishers or angler associations co-responsible for the management of inland resources in European rivers and lakes.

Download or read book Towards Global Sustainable High Seas Fisheries A critical assessment written by Elise Verdonck and published by GRIN Verlag. This book was released on 2014-11-25 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2014 in the subject Politics - Environmental Policy, grade: A-, University of Auckland, course: International Environmental Law, language: English, abstract: The crucial role of the oceans in the climate and functioning of the planet is an undeniable fact. Oceans cover over 70 percent of the earth’s surface and house a major part of global biodiversity. Ocean ecosystems support all life on earth: they regulate the global temperature, provide rain, food and oxygen, and they manage a certain amount of human pollutants. Nearly 64 percent of the oceans lie far beyond the coast of individual states. The high seas and the deep seabed, which form the parts of the oceans that are beyond the national jurisdiction of coastal countries, are some of the least protected areas on earth. Because of its very low temperature, lack of light and energy-deprived character, the high seas were long considered hostile to life. For centuries those areas beyond national jurisdiction (ABNJ) were being treated as a virtual desert without any sign of life or resources. Until the later decades of the twentieth century, the deep sea with its rare organisms and unique ecosystems was largely unexplored by humans. This resulted in a collective lack of knowledge about the rich biodiversity and abundant resources of the high seas and the deep seabed. In recent decades, human interest and activities outside the limits of coastal state jurisdiction have increased. Reasons of the sudden interest in those unknown parts of the oceans were inter alia the depletion of fishery stocks within national jurisdiction, the expansion of global maritime trade, the search for new resources and scientific interest in the deep sea. New advances in technology and maritime transport made it possible for scientists to explore the mysterious uncharted parts of the oceans. This essay will focus on one particular part of the global biodiversity, namely the high seas fish stocks. There is a worldwide increasing demand for seafood. Consequently, a global industry is developed with more and bigger ships. The increased pressure on high seas fish stocks has caused a crisis in the current high seas fisheries management. Over 32 percent of the fish stocks are overexploited, depleted or still recovering from depletion. Global fishing activities will have to become subject to sustainable management measures if we want to secure the fisheries' benefits for the long term. Sustainable management of wild fish stocks causes beneficial effects for the economic output, livelihoods and food security.

Download or read book The Behavior Ecology and Evolution of Cichlid Fishes written by Maria E. Abate and published by Springer Nature. This book was released on 2021-09-19 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River. Dramatic new molecular evidence draws attention to the complex taxonomy and systematics of Neotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.

This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.
Download or read book Aquatic Biodiversity II written by H. Segers and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.

Download or read book The Sava River written by Radmila Milačič and published by Springer. This book was released on 2014-11-05 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview of environmental aspects of the Sava River, which is the greatest tributary to the Danube River and the major drainage river system of South Eastern Europe. Hydroelectric power plants, river traffic, intensive agricultural activities, heavy industry and floods have considerable influence on the environment and biota in the basin. Summarizing the results that were gathered in the course of EU, bilateral and national projects, the book highlights the most important stressors and helps readers to better understand the impact of anthropogenic activities on the function of river basins. Topics include: transboundary water cooperation between the riparian countries; climate change projection, including its impact on flood hazards; evaluation of anthropogenic pollution sources; pollution of sediments, metal bioavailability and ecotoxicological and microbiological characterization of the river. The biological part also addresses quality aspects related to wildlife in river aquatic ecosystems (algae, macrophytes, zooplankton, macroinvertebrates and fish) and riparian ecosystems (amphibians, reptiles, birds and mammals). The general state of biodiversity and pressures caused by invasive aquatic species are also discussed.

Download or read book Invasion Dynamics written by Cang Hui and published by Oxford University Press. This book was released on 2017-01-26 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have moved organisms around the world for centuries but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing, and proposing a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It discusses not only key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analyzing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management.
