Environmental Best Management Practices for Aquaculture (Hardcover): C.S. Tucker Environmental Best Management Practices for Aquaculture (Hardcover)
C.S. Tucker
R5,953 Discovery Miles 59 530 Ships in 10 - 15 working days

Published in Cooperation with THE UNITED STATES AQUACULTURE SOCIETY
Population growth and increased appreciation of seafood's role in human health have pushed global seafood consumption past the point where capture fisheries can meet demand. Aquaculture--farming aquatic plants and animals in oceans and inland waters--has expanded rapidly in the past decade in response to the increased demand for fishery products. The rapid growth of aquaculture domestically and internationally has stimulated concerns over social and environmental impacts caused by increased production of farmed aquatic species. Environmental advocacy groups and government regulatory agencies have called for better management to address potentially negative impacts and assure sustainable aquaculture development. Environmental Best Management Practices for Aquaculture is the first synthesis of best management practices that minimize environmental impacts.
Environmental Best Management Practices for Aquaculture provides technical guidance to improve the environmental performance of aquaculture. This book is the only comprehensive guide to best management practices for mitigation of environmental impacts of aquaculture. The book addresses development and implementation of best management practices, practices for specific aquaculture production systems, and the economics of implementing best management practices.
Environmental Best Management Practices for Aquaculture includes contributions from internationally recognized experts in environmental management and aquaculture from academia, government, and non-governmental organizations. The book is a valuable reference for innovative producers, policy makers, regulators, research scientists, and students.

"...this book covers a range of algal phyla, specialised algal bioprocessing and application topics that make it very interesting for a broad audience. Each chapter covers a theme in such a way that can easily be read by a non-specialist but, as the authors incorporate recent published papers, the book will also be interesting for experts...I also recommend the book for entrepreneurs and technical staff working in different algal-based operations." (Journal of Phycology) As the global demand for meat increases due to population and economic growth, more pressure has been placed on the animal feed sector to support sustainable livestock production, whilst also ensuring the nutritional value and palatability of feed. With traditional sources of protein, including oilseeds and distiller grains, considered as major contributors to climate change, there is growing interest in establishing alternative, more 'climate-smart' sources of protein, such as seaweed and other forms of microalgae that can supplement livestock diets. Seaweed and microalgae as alternative sources of protein summarises current advances in utilising macroalgae and microalgae as alternative sources of proteins. The collection reviews processes of protein formation in macroalgae and microalgae, macroalgae farming and processing as well as microalgae bioprocessing. Chapters also discuss the practical application of seaweed as an alternative protein source in ruminant, pig, poultry and fish diets. Edited by Professor Xin Gen Lei, Cornell University, USA, Seaweed and microalgae as alternative sources of protein will be a standard reference for researchers from universities or other research centres involved in macroalgae/microalgae production and livestock nutrition, companies involved in the manufacture or supply of animal feed or livestock nutrition services, government and other agencies regulating the animal feed sector, as well as farmers interested in furthering their knowledge on recent developments in the animal feed/livestock nutrition sector.

Becoming Salmon - Aquaculture and the Domestication of a Fish (Hardcover): Marianne Elisabeth Lien Becoming Salmon - Aquaculture and the Domestication of a Fish (Hardcover)
Marianne Elisabeth Lien
R2,050 R1,936 Discovery Miles 19 360 Save R114 (6%) Ships in 12 - 19 working days

Becoming Salmon is the first ethnographic account of salmon aquaculture, the most recent turn in the human history of animal domestication. In this careful and nuanced study, Marianne Elisabeth Lien explores how the growth of marine domestication has blurred traditional distinctions between fish and animals, recasting farmed fish as sentient beings, capable of feeling pain and subject to animal-welfare legislation. Drawing on fieldwork on and off salmon farms, Lien follows farmed Atlantic salmon through contemporary industrial husbandry, exposing how salmon are bred to be hungry, globally mobile, and "alien" in their watersheds of origin. Attentive to both the economic context of industrial food production and the materiality of human-animal relations, this book highlights the fragile and contingent relational practices that constitute salmon aquaculture and the multiple ways of "becoming salmon" that emerge as a result.
