Off-Flavors in Aquaculture discusses types of off-flavors, analytical detection methods for off-flavor compounds, and pre-harvest and post-harvest management practices for preventing and dealing with off-flavor in aquaculture products such as catfish, shellfish, shrimp, tilapia, and trout.

The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).

Aquaculture is an increasingly diverse industry with an ever-growing number of species cultured and production systems available to professionals. A basic understanding of production systems is vital to the successful practice of aquaculture. Published with the World Aquaculture Society, Aquaculture Production Systems captures the huge diversity of production systems used in the production of shellfish and finfish in one concise volume that allows the reader to better understand how aquaculture depends upon and interacts with its environment. The systems examined range from low input methods to super-intensive systems. Divided into five sections that each focus on a distinct family of systems, Aquaculture Production Systems serves as an excellent text to those just being introduced to aquaculture as well as being a valuable reference to well-established professionals seeking information on production methods.

Seafoods are important sources of nutrients for humans. Proteins and non protein nitrogenous compounds play an important role in the nutritional value and sensory quality of seafoods. Consumption of fish and marine oils is also actively encouraged for the prevention and treatment of cardio vascular diseases and rheumatoid arthritis. Highly unsaturated long-chain omega-3 fatty acids are regarded as the active components of marine oils and seafood lipids. The basic chemical and biochemical properties of seafood proteins and lipids, in addition to flavour-active components, their microbiological safety and freshness quality, are important factors to be considered. A presentation of the state-of-the-art research results on seafoods with respect to their chemistry, processing technology and quality in one volume was made possible by cooperative efforts ofan international group of experts. Following a brief overview, the book is divided into three sections. In Part 1 (chapters 2 to 8) the chemistry of seafood components such as proteins, lipids, flavorants (together with their properties and nutritional significance) is discussed. Part 2 (chapters 9 to 13) describes the quality of seafoods with respect to their freshness, preservation, micro biological safety and sensory attributes. The final section of the book (chapters 14 to 16) summarizes further processing of raw material, underutilized species and processing discards for production of value added products.

This book is a single convenient source of information that covers priority areas of research in channel catfish aquaculture. Recent Developments in Catfish Aquaculture compiles some of the latest research in the field as presented at the Catfish Research Symposium. The editors present a diverse collection of chapters that illustrates recent research efforts in catfish culture and shows the scope of research that is being conducted in nutrition, genetics, water quality management, economics, fish health, and pond production systems. Some of the contributing authors’chapters are developmental but many contain information that can be immediately applied to commercial situations to improve production efficiency. A variety of subjects are covered in this catfish resource, including: Health Issues: immunology, vaccination, selection, drug evaluation, nutritional causes Genetics: hybridization, selection Hatchery Management: new techniques to incubate eggs; control of fungus on developing eggs; evaluation of mechanical graders Production Economics: comparison of different approaches Water Quality: discovery and identification of an algae that kills catfish; off-flavor; water circulators Nutrition: effects of feed on growth and fattiness of fish; nutritionally induced health problems Food Technology: impedance microbiology for evaluation and safety of processed catfish Behavior: behavioral interactions and feeding behavior Recent Developments in Catfish Aquaculture shows the paradox that exists in catfish farming research. On one hand, extremely sophisticated research is being used to solve complex problems. On the other, the basic method of raising catfish has not yet been determined. Several chapters describe important new developments in the field and will lead to important breakthroughs and developments in the future. This volume is required reading for those conducting catfish research or catfish culture, including university and federal aquaculture researchers as well as students. They will find it useful as a reference guide, and catfish farmers will find it helpful as a guide to recent advances in production technology.

Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.

Presenting state-of-the-art research on the economics of producing and marketing aquacultural products, this volume addresses critical issues concerning profitability, market acceptance, and economic modeling of various aquacultural products. Research approaches range from firm-level bioeconomic modelling to market-level econometric modelling of industry growth and product substitution. The studies highlight the institutional structures and public policy issues that will shape growth and development of aquaculture into the twenty-first century, including trade policies, food safety, and environmental quality.
