Available in PDF, EPUB and Kindle. Book excerpt/synopsis : The culmination of over a decade's worth of research by the Pond Dynamics/Aquaculture Collaborative Research Support Program (CRSP), Dynamics of Pond Aquaculture not only explains the physical, chemical, and biological processes that interact in pond culture systems, but also presents real-world research findings and considers the people who depend on these systems. This book uses data from CRSP field research sites in East Africa, Southeast Asia, Central America, and North America to present a complete picture of the pond system and the environment in which it exists. A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.

This book was released on 2012-12-06 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt/synopsis : 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).

Available in PDF, EPUB and Kindle. Book excerpt/synopsis : Pond treatment technology is used in tens of thousands of applications serving many millions of people across the globe - why? Simply because it is efficient and effective. While pond treatment technology offers relative simplicity in its application, it incorporates a host of complex and diverse mechanisms that work to treat and cleanse polluted waters before their return to our environment. This book offers a comprehensive review of the pond technology field including the newest ideas and latest findings. Topics covered include: The physical, chemical and biological characteristics of the pond environment; A detailed review of pond treatment mechanisms and performance; Comprehensive guidance on pond design, operation and upgrade options; A range of chapters summarising new and emerging pond technologies; The integration of ponds with wetlands and aquaculture systems and their use as storage reservoirs; Special applications of pond technology in cold climates, for agricultural wastes and for treatment of stormwater. The objective of this book is to get this wealth of knowledge "out there" to the users to ensure the continuous improvement and ongoing success of this crucial technology.

This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt/synopsis : Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.

Book excerpt/synopsis : A Mildred L. Batchelder Honor Book and an ALA-ALSC Notable Children’s Book, The Lily Pond continues the story of two Jewish sisters who left Austria during WWII/Holocaust and found refuge in Sweden. A year after Stephie Steiner and her younger sister, Nellie, left Nazi-occupied Vienna, Stephie has finally adapted to life on the rugged Swedish island where she now lives. But more change awaits Stephie: her foster parents have allowed her to enroll in school on the mainland, in Goteberg. Stephie is eager to go. Not only will she be pursuing her studies, she'll be living in a cultured city again—under the same roof as Sven, the son of the lodgers who rented her foster parents' cottage for the summer. Five years her senior, Sven dazzles Stephie with his charm, his talk of equality, and his anti-Hitler sentiments. Stephie can't help herself—she's falling in love. As she navigates a sea of new emotions, she also grapples with what it means to be beholden to others, with her constant worry about what her parents are enduring back in Vienna, and with the menacing spread of Nazi ideology, even in Sweden. In these troubled times, her true friends, Stephie discovers, are the ones she least expected.

This book was released on 2019-04-17 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt/synopsis : During his two-year residence at Walden Pond, Henry David Thoreau became keenly aware of the natural world that surrounded him. Entries from his journals reflect his soulful, in-depth observations of local wildlife, and his remarks on birds are particularly plentiful and poetic. This book, originally published as Notes on New England Birds in 1910 and edited and arranged by Francis H. Allen, collects Thoreau's thoughts on the various bird species that populated the New England woods, from the great blue heron to the kingbird and the American finch. "Open to any page and you will find, besides apt descriptions of the natural world, a cogent remark or a philosophical observation," noted The Washington Post. Bird lovers and watchers, fans of Thoreau, and naturalists and environmentalists will delight in joining the author as he saunters through the woods and ponders the region's abundant wildlife. A new selection of 16 full-page color illustrations by John James Audubon enhances the text.
