Emerging Technologies Environment And Research For Sustainable Aquaculture

Traditional aquaculture and fishery systems have caused a series of ecological and environmental problems. For the purpose of sustainable development, new technologies and policies are highly needed in the field of aquaculture and fisheries. This book mainly focuses on two topics, technologies and environment, and sustainable aquaculture. It is expected that this book can help researchers and technicians in the aquaculture industry to get more new ideas and techniques.

With wild stocks declining due to over-fishing, aquaculture will have a more significant role to play in meeting future demand for fresh fish. Developments in research continue to lead to improvements in aquaculture production systems, resulting in increased production efficiency, higher product quality for consumers and a more sustainable industry. New technologies in aquaculture reviews essential advances in these areas. Part one focuses on the genetic improvement of farmed species and control of reproduction, with chapters on genome-based technologies in aquaculture research, selective breeding and the production of single sex and sterile populations, among other topics. Parts two and three review key issues in health, diet and husbandry, such as the control of viral and parasitic diseases, diet and husbandry techniques to improve disease resistance, advances in diets for particular fish species and the impact of harmful algal bloom on shellfisheries aquaculture. Chapters in Parts three and four then examine the design of different aquaculture production systems, including offshore technologies, tank-based recirculating systems and ponds, and key environmental issues, such as the prediction and assessment of the impact of aquaculture. Concluding chapters focus on farming new species. With its well-known editors and distinguished international team of contributors, New technologies in aquaculture is an essential purchase for professionals and researchers in the aquaculture industry. Reviews recent advances in improvements in aquaculture production Focuses on the genetic improvement and reproduction of farmed species, including genome-based technologies Discusses key health issues, including advances in disease diagnosis, vaccine development and other emerging methods to control pathogens in aquaculture

This book is about important relevant recent research topics in sustainable aquaculture practices. A critical assessment of the sustainable fishing methods and the aspect of sustainable aquaculture feed is presented in this volume. A special focus has been given to socio-economic and environmental assessment of aquaculture practices and analysis of carbon footprint under an intensive aquaculture regime. Aquaponics as a niche for sustainable modern aquaculture has been highlighted. The effect of use of pharmaceuticals to prevent fish disease on the surrounding marine environment is an emerging area of concern, and a critical discussion on this aspect is included in the book. The spread of organic waste and nutrients released by fish farms to natural water bodies has raised considerable concerns. Therefore the methods to prevent their dispersion and removal (treatment) have been comprehensively covered in this book. This book is an essential read for academician, researchers, and policy makers in the field of aquaculture.

Published in Cooperation with THE UNITED STATES AQUACULTURE SOCIETY As aquaculture production continues to grow and develop there is a continuous search for new species to culture to be able to fully exploit new national and international markets. Species selection for aquaculture development often poses an enormous challenge for decision makers who must decide which species and culture technologies to support with public resources, and then how best to divide those resources. Species and System Selection for Sustainable Aquaculture brings together contributions from international experts with experience in identifying potential species and production systems for sustainable aquaculture with a socioeconomic focus. The book is divided into three sections: Principles, Practices, and Species-Specific Public Policy for Sustainable Development. An outgrowth of a workshop held as part of the Aquaculture Interchange Program with examples from around the globe carefully edited by PingSun Leung, Pat O'Bryen, and Cheng-Sheng Lee this volume will be an important reference for all researchers, professionals, economists, and policy-makers involved in selecting new species for the development of sustainable aquaculture.

This edited book presents the emerging sustainable innovations in all areas of aquaculture in Africa with a view to create an opportunity whereby scientific outputs and recommendations can be endorsed for improved aquaculture outputs towards poverty alleviation and food security on the continent. Food insecurity and poverty are some of the challenges faced on the African continent. These challenges are further exacerbated by the growing human population and the impacts of climate change. Today, aquaculture has become one of the fastest food producing sectors in the world, with the potential to contribute significantly to food security and poverty alleviation in developing countries. In Africa, aquaculture is at an infant stage, however, many African countries have recognized the potential roles of aquaculture in food security, poverty alleviation and conservation of aquatic resources through their commitment to achieve the United Nation Sustainable Development Goals. The book reviews and synthesize research work from these thematic areas across Africa and provide a unique perspective on the emerging aquaculture innovations and illustrate how aquaculture practices could be feasible and cost effective while promoting social and environmental sustainability. The book also draws from global discussions on sustainable aquaculture practices and provides recommendations on what is feasible for Africa. This book is a great tool for the university students, scholars, aquaculture farmers, investors, and policymakers to understand the scientific based sustainable aquaculture innovations from an African perspective. This book is focused on SDG 2 and SDG 14.

This book seeks to address the challenges facing the international seafood industry via a two pronged approach: by offering the latest information on established technologies and introducing new ideas and technologies. An introductory chapter sets the tone for the book by presenting the background against which fish processing will exist in the near future. Chapter two looks at the environmental and sustainability issues relating to conventional fish processing, including processing efficiency and better use of the outputs currently considered wastes. The impact of mechanisation and computerisation on environmental sustainability is also addressed. Subsequent chapters examine the latest developments in established fish processing technologies such as canning, curing, freezing and chilling, with an emphasis on the environmental aspects of packaging and the process itself. In addition, quality and processing parameters for specific species, including new species, are described. The second part of the book gives authors the opportunity to introduce the potential technologies and applications of the future to a wider audience. These include fermented products and their acceptance by a wider audience; the utilisation of fish processing by-products as aquaculture feeds; and the use of by-products for bioactive compounds in biomedical, nutraceutical, cosmetic and other applications.

Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the ‘green revolution’ before it, the ‘blue revolution’ in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture’s ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam,nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).
