Book Description
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.

Book Description
For two decades the idea of governments and fishers working together to manage fisheries has been advocated, questioned, disparaged and, most importantly, attempted in fisheries from North and South America through Europe, Africa, Asia and Oceania. This book is the first time these experiences have been pulled together in a single volume, summarized and explained. The Fisheries Co-management Experience begins with a review of the intellectual foundations of the co-management idea from several professional perspectives. Next, fisheries researchers from six global regions describe what has been happening on the ground in their area. Finally, the volume offers a set of reflections by some of the best authors in the field. The end result describes both the state-of-the-art and emerging issues for one of the most important trends in natural resources management.

Book Description
This handbook summarises the experience gained over recent years in fishery statistical development by the Fishery Information, Data and Statistics Unit of the FAO, and provides guidance for developing and implementing cost-effective and sustainable fishery surveys. The methodological and operational concepts discussed apply equally to marine and inland capture fisheries. The emphasis is placed on the understanding and interpretation of the statistics, rather than on the computations producing them.

Book Description
This book presents the results from the Japanese Fisheries Research Agency’s 3-year intensive monitoring of radionuclides in a variety of fish, plankton, benthos, and their living environments after the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in March 2011. The book reveals the dynamics of contamination processes in marine and freshwater fish, mediated by the contamination of water, sediments, and food organisms; it also clarifies the mechanisms by which large variations in the level of contamination occurs among individual fish. Most importantly, the book includes a large amount of original measurement data collected in situ and for the first time assesses diffusion of radiocesium across the Pacific using both in situ data and a numerical simulation model. Also introduced are several new approaches to evaluate the impact of the release of radionuclides, including the measurement of radiation emission from an otolith section to identify the main period of contamination in fish. The FNPP accident represents a rare instance where the environmental radioactivity level was elevated steeply through atmospheric fallout and direct discharge of radioactive water into the sea over a short period of time. Replete with precise scientific data, this book will serve as an important resource for research in fields such as fishery science, oceanography, ecology, and environmentology, and also as a solid basis for protecting fisheries from damage resulting from harmful rumors among the general public.
