Fish farming has increased in status equal to cattle farming as a source of food for mankind. In developing countries fish and shellfish provide inexpensive animal protein, while in developed countries aquaculture is expected to produce more fish and shellfish as a source of low-calorie protein for health conscious individuals. In such an era, knowledge of fish farming technologies of different countries, strongly influenced by cultural factors, is of valuable importance. The primary production techniques of fish farming in Japan described here have an emphasis on practical technology. This second edition reflects the changes in both quantity of production and technology in Japanese aquaculture. The statistics have been revised and the text rewritten to suit the current status of aquaculture in Japan; new aquaculture species have been included and discussions on marine ranching and biotechnology for aquaculture added.

This is the first English book to address the current development of closed recirculating aquaculture systems (cRASs) in Japan, and its implications for industry in the near future. It offers an introduction to the topic and discusses the industrial application of cRASs. Around Europe, cRASs using freshwater have been developed, but to date there is little information about cRASs using the saltwater. As such, the book introduces the technical development of cRASs using the saltwater in Japan and describes measures necessary for their industrialization. It also discusses in detail various species, e.g., flounder, pejerrey, kuruma shrimp, white shrimp and abalone, which have been raised in cRASs. Furthermore, it presents wide topics concerning the technological development of aquariums, an area in which progressive Japanese techniques dominate. Lastly, the book also examines CERAS and poly-culture in Japan. The book is a valuable resource for a wide readership, such as local government officers, energy-industry staff, maintenance and system engineers, as well as those from the construction, agriculture and fishery industries.

Download Revitalization and Internal Colonialism in Rural Japan Book in PDF, Epub and Kindle

This book explores the decline of rural and peripheral areas in Japan, which results from an aging population, outmigration of the younger generations, and the economic decline of the primary sector. Based on extensive original research, the book examines in detail the case of the Noto peninsula. Allowing the locals to tell their stories, describe their problems, and come up with possible solutions, the book demonstrates the serious impact of rural decline on their daily life and work and highlights the struggle to sustain rural living in the globalized age. It argues that some recent innovations in global media, economy, technology, and ideology offer scope for reversing the decline, as some central government initiatives do, but that these are not always noticed, appreciated, and made use of by local people. The book also discusses the nature of the links between the peripheries and the centres – regional, national, and global – and how these often take the form of "internal colonialism."

As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology. The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.
