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

The main themes of the Symposium were biodiversity in enclosed and semi-enclosed seas and artificial habitats, and the restoration of degraded systems. These themes are highly relevant today. The papers dealing with the first theme represent current research and concerns about marine biodiversity in enclosed seas. The papers in the second theme represent a synthesis of up-to-date knowledge on artificial habitats.

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.

Inspired by the International White Shark Symposium in 2010, Global Perspectives on the Biology and Life History of the White Shark incorporates the most important contemporary research findings into a single peer-reviewed book. This beautifully illustrated reference represents a historic change in the context of White Shark (Carcharodon carcharias) research. Once considered one of the most poorly understood and difficult sharks to study, this timely book recognizes a new sophisticated focus on the White Shark, raising its status from obscurity to enlightenment. The Global Perspectives on the Biology and Life History of the White Shark celebrates the White Shark as the most studied shark in the sea. Within the chapters one can find new insights into a vast range of topics, such as behavior, physiology, migration patterns, habitat preferences, daily activity patterns, molecular genetics, reproductive biology and new research methods. The book also delves into population monitoring and policy options for managers and researchers.
