The global expansion of aquaculture production and its future role as a food supplier to human society has environmental, social and economic limitations, affecting marine ecosystems and socio-economic scales from local to global. The expansion is closely linked with human health requirements and societal needs for various goods and services provided by marine ecosystems. This book provides a scientific forecast of the development in aquaculture with a focus on the environmental, technological, social and economic constraints that need to be resolved to ensure sustainable development of the industry and allow the industry to be able to feed healthy seafood products to the future generations. The chapters included discuss the most critical bottlenecks of the development encompassing subjects of understanding the environmental impacts, the current state-of-art in monitoring programs and in coastal zone management, the important interactions between wild and cultured organisms including release of non-native species into the wild, the current trends within the development of aquafeeds along with human health aspects as well as the political, socio-economic and economic trends within the industry including a chapter on approaches taken by Non Governmental Organisations (NGOs) to aquaculture. Finally the last chapter provides different future scenarios of the industry based on the identified bottlenecks. more...

This important book draws together, for the first time, a vast wealth of information on all major aspects of the farming of Arctic charr, a highly prized and commercially valuable salmonid. The author, Gavin Johnston who has many years' experience of farming Arctic charr, teaching about and researching the species, has produced a book that is a landmark publication and an essential purchase for all those involved with the species. The book is broadly divided into three sections. The first section covers Arctic charr interactions with humans and the charr's biological requirements for culture. Section two is a practical guide to the art and science of early-rearing Arctic charr; a hands on application of current knowledge in Arctic charr aquaculture. The final section of the book focuses on the commercial production of Arctic charr, providing cutting-edge information for all those involved in the exploitation of this valuable species. Arctic Charr Aquaculture is an essential purchase for anyone involved in, or considering involvement in farming of this species. Farm managers and other personnel in fish farms and experimental aquaculture units, fish and aquatic biologists will find a huge amount of useful data in this book. Libraries in all university departments and research establishments where aquaculture, fisheries and fish biology are studies and taught should have copies of this book on their shelves. This book brings together for the first time the knowledge needed to farm and market Arctic Charr. Part One is an overview of Arctic Charr aquaculture beginning with the history and development of Charr aquaculture, the biological attributes of Arctic Charr, the physical requirements for growth and commercial production requirements. Other chapters are devoted to Charr health, nutrition and feeding. Part Two is a practical guide for the producer operating an Arctic Charr farm either as a vertically integrated operation or as discrete hatcheries and grow out farms. more...

Bird lovers, take heart! While the birding literature is filled with tales of expert observers spotting rare species in exotic locales, John Yow's The Armchair Birder is here to remind us that the most fascinating birds can be the ones perched right outside our windows. In thirty-five engaging, humorous, and even irreverent essays, Yow reveals the fascinating lives of birds you probably already recognize and naturally want to know more about, because they're the ones you see nearly every day. Following the seasons of the year, Yow covers forty-two species, from the Carolina wren that rings in the springtime to the sandhill crane croaking high overhead at the end of winter. Leisurely and entertaining, the essays explore the improbable, unusual, and comical aspects of their subjects' lives—from the philandering of the ruby-throated hummingbird to the occasional dipsomania of the cedar waxwing. Rather than bare facts and field marks, The Armchair Birder offers observations, anecdotes, and stories—not only Yow's own, but also those of America's classic bird writers, such as John James Audubon, Arthur Bent, and Edward Forbush, experts who saw it all and wrote with wit and passion. With The Armchair Birder, backyard birders will take new delight in the birds at their feeders, while veteran check-listers will enjoy putting their feet up. All will applaud this unique addition to bird literature, one that combines the fascination of bird life with the pleasure of good reading. more...
