This book was released on 2013-10-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial habitats have been used for centuries to successfully modify environments for the benefit of Man. In the aquatic environment, the use of artificial habitat technologies is of growing interest worldwide. Opportunities exist in both developed and developing nations to apply these technologies in many areas, including classical scientific investigations of ecosystem structure and function, engineering advances in underwater technology, and fisheries and environmental management. The applications of artificial habitat technologies are taking on ever greater economic, social, and environmental importance globally, not only in developed countries such as Japan where highly sophisticated technologies are used, but also in developing nations, where lower cost practices are in use. There is growing pressure to increase production, while at the same time preserve or enhance the environments and ecosystems surrounding fisheries. This book provides a comprehensive review of the facts, issues, and global trends emerging regarding the use of artificial habitats in aquatic ecosystems. It presents the most recent scientific advances in ecology and engineering technologies related to the building of artificial habitats, and it also presents many of the fisheries management and socioeconomic and environmental issues. Artificial Habitats for Marine and Freshwater Fisheries will be of interest to a broad audience including natural resource scientists, planners, and managers, particularly those interested in aquatic and fisheries science and management; organizations and individuals interested in commercial and recreational fishing; ecologists; environmental economists, engineers, lawyers, and social scientists; and geographers. Presents a global scope Draws together, for the first time, disparate literature Contains contributions by authors in the United States and Japan Features engineering chapters that focus on Japanese advanced technology often not available to the English language audience

Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.

Book excerpt: Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.

This book was released on 1996-01-26 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.

This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
