Book Description
The output from world aquaculture, a multi-billion dollar global industry, continues to rise at a very rapid rate and it is now acknowledged that it will take over from fisheries to become the main source of animal and plant products from aquatic environments in the future. Since the first edition of this excellent and successful book was published, the aquaculture industry has continued to expand at a massive rate globally and has seen huge advances across its many and diverse facets. This new edition of Aquaculture: Farming Aquatic Animals and Plants covers all major aspects of the culture of fish, shellfish and algae in freshwater and marine environments. Subject areas covered include principles, water quality, environmental impacts of aquaculture, desert aquaculture, reproduction, life cycles and growth, genetics and stock improvement, nutrition and feed production, diseases, vaccination, post-harvest technology, economics and marketing, and future developments of aquaculture. Separate chapters also cover the culture of algae, carps, salmonids, tilapias, channel catfish, marine and brackish fishes, soft-shelled turtles, marine shrimp, mitten crabs and other decapod crustaceans, bivalves, gastropods, and ornamentals. There is greater coverage of aquaculture in China in this new edition, reflecting China's importance in the world scene. For many, Aquaculture: Farming Aquatic Animals and Plants is now the book of choice, as a recommended text for students and as a concise reference for those working or entering into the industry. Providing core scientific and commercially useful information, and written by around 30 internationally-known and respected authors, this expanded and fully updated new edition of Aquaculture is a book that is essential reading for all students and professionals studying and working in aquaculture. Fish farmers, hatchery managers and all those supplying the aquaculture industry, including personnel within equipment and feed manufacturing companies, will find a great deal of commercially useful information within this important and now established book. Reviews of the First Edition "This exciting, new and comprehensive book covers all major aspects of the aquaculture of fish, shellfish and algae in freshwater and marine environments including nutrition and feed production." —International Aquafeed "Do we really need yet another book about aquaculture? As far as this 502-page work goes, the answer is a resounding 'yes'. This book will definitely find a place in university libraries, in the offices of policy-makers and with economists looking for production and marketing figures. Fish farmers can benefit greatly from the thematic chapters, as well as from those pertaining to the specific plant or animal they are keeping or intending to farm. Also, they may explore new species, using the wealth of information supplied." —African Journal of Aquatic Science "Anyone studying the subject or working in any way interested in aquaculture would be well advised to acquire and study this wide-ranging book. One of the real 'bibles' on the aquaculture industry." —Fishing Boat World and also Ausmarine

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
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).
