Fisheries Science Series – serie

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.

This book explores how we can solve the urgent problem of optimizing the use of variable, uncertain but finite fisheries resources while maintaining sustainability from a marine-ecosystem conservation perspective. It offers readers a broad understanding of the current methods and theory for sustainable exploitation of fisheries resources, and introduces recent findings and technological developments. The book is divided into three parts: Part I discusses fish stock dynamics, and illustrates how ecological processes affecting life cycles and biological interactions in marine environments lead to fish stock variability in space and time in major fish groups; small pelagic fish, demersal fish and large predatory fish. These insights shed light on the mechanisms underlying the variability in fish stocks and form the essential biological basis for fisheries management. Part II addresses the technologies and systems that monitor changes in fisheries resources and marine ecosystems using two approaches: fishery-dependent and fishery-independent data. It also describes acoustic surveys and biological sampling, as well as stock assessment methods. Part III examines management models for effectively assessing the natural variability in fisheries resources. The authors explore ways of determining the allowable catch in response to changes in stock abundance and how to incorporate ecological processes and monitoring procedures into management models. This book offers readers a broad understanding of sustainable exploitation as well as insights into fisheries management for the next generation.

This book highlights the latest advances in rotifer studies in various fields including aquaculture, ecology, gerontology and ecotoxicology. The genus Brachionus are an indispensable type of zooplankton, having served as an initial live food for marine larval rearing since the 1960s. Their mass culture techniques have been intensively studied, and some essential achievements have been made – regarding high density culture, employment of valuable dietary algae, automated culture systems, and effective production of resting eggs.  These have in turn supported stable and efficient aquatic seedling production for numerous important marine fish species including flounder, sea bream, and bluefin tuna.  Further, this group is considered to be a suitable model for studying various aspects in ecology.  A series of aquaculture and basic science studies have significantly advanced our understanding of the life history evolution. The studies in these two fields are closelylinked, and provide readers with comprehensive information on how rotifers are now being employed in biological investigations.

This book is a compilation of eel research and fish migration studies for more than 40 years showing the research history and recent advances in eel studies. Dr. Katsumi Tsukamoto, the esteemed editor of this book, has been actively involved in eel research as one of the leading scientists in the world for a long time, and he and his team successfully collected the fertilized eggs and spawn-condition adult eels from the wild for the first time in the world. This book compiles the essentials of the scientific findings obtained by the editor and his colleagues and reviews the latest references of eel science. Knowledge and information in the book such as a spawning area survey, research on artificial production of glass eels, the discovery of a new species, etc. will attract the reader’s interest, as these are written based on the authors’ experiences. Readers can obtain a comprehensive understanding of eels from various aspects of eel science including the cultural and socio-economic importance of eels and valuable scientific information using state-of-the-art approaches. The book also endeavors to contribute to the conservation of eel species, some of which have been classified as endangered by the IUCN and to promoting harmonious coexistence between humans and nature.
