This book elucidates the vital but often neglected relationship between bottom soil and water quality. An understanding of this important connection is essential for maintaining water quality within optimum ranges for shrimp and fish. It is the first volume to provide information on topics from soil science essential to pond aquaculture. The impact of soil-water interactions on water quality is examined, and the volume provides important methods for enhancing the soil conditions in ponds. Detailed chapters include coverage of *soils in pond aquaculture *physical, chemical, and mineralogical properties of soil *soil nutrients *the exchange of dissolved substances between soil and water *soil organic matter, anaerobic respiration, and oxidation-reduction *sediment soil *relationships to aquatic animal production *pond bottom management and soil analyses. Bottom Soils, Sediment, and Pond Aquaculture gives students and professionals in aquaculture insight into the principles of soil science which most affect pond management and provides them with an essential and current reference.
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.
Examines the life in and around a pond, including bullfrogs, crayfish, and snapping turtles.

A classic revolutionary novel of the 1930s and the first complete work written by a woman before the Korean War to be published in English, From Wonso Pond transforms the love triangle between three protagonists into a revealing portrait of the living conditions that led to modern Korea, both North and South. "A fatherless young girl now poised to become the victim of [the landlord's] lecherous fangs and paws," begins one of the original newspaper teasers describing From Wonso Pond and the fate of its heroine, Sonbi. In a plot rich with Dickensian overtones, the novel paints a vivid picture of life in what is now North Korea through the eyes of Sonbi, her childhood neighbor, Ch’otchae, and a restless law student, Sinch’ol, as they journey separately from a small, impoverished village ruled by the lecherous land baron to the port city of Inch’on. But life is hardly easier there, as Sonbi wears herself out boiling silk threads twelve hours a day while Ch’otchae and Sinch’ol load rice on the docks. All three become involved with underground activists, fighting the oppression of country and city, as well as their Japanese colonial rulers.
The only hope of supplying the world's ever-increasing demand for aquatic food products is through aquaculture, and the vast majority of this is conducted in ponds. Although pond aquaculture may appear at first to be an archaic method of growing aquatic animals, it is one that is consistently profitable when the pond is managed properly. The most important aspect of pond management is the maintenance of adequate environmental conditions for good growth and health of the animal under culture. Water quality in ponds also extends into the areas of environmental protection and food quality and safety, which are increasingly important in today's world. This book provides the most complete, up-to-date account of water quality and its management in aquaculture ponds. It provides background information on the physical, chemical, and biological environment of pond aquaculture, and illustrates how the proper balance of these factors is the essential ingredient for successful production of fish and other aquatic animals. Management techniques for the control of water quality and productivity include liming, fertilization, mechanical aeration, water exchange, and the use of algicides and herbicides. The authors examine the effects of pollution on aquaculture and the validity of current criticisms by environmentalists. This book will be of great benefit to students, extension agents, policy-makers, government officials and the commercial aquaculture industry.
In 1979, several graduate students in the Department of Fisheries and Allied Aquacultures at Auburn University met with one of the authors (CEB) and asked him to teach a new course on water supply for aqua culture. They felt that information on climatology, hydrology, water distribution systems, pumps, and wells would be valuable to them. Most of these students were planning to work in commercial aquaculture in the United States or abroad, and they thought that such a cdurse would better prepare them to plan aquaculture projects and to communicate with engineers, contractors, and other specialists who often become involved in the planning and construction phases of aquaculture en deavors. The course was developed, and after a few years it was decided that more effective presentation of some of the material could be made by an engineer. The other author (KHY) accepted the challenge, and three courses on the water supply aspects of aquaculture are now offered at Auburn University. A course providing background in hydrology is followed by courses on selected topics from water supply engineering. Most graduate programs in aquaculture at other universities will even tually include similar coursework, because students need a formal intro duction to this important, yet somewhat neglected, part of aquaculture. We have written this book to serve as a text for a course in water supply for aquaculture or for individual study. The book is divided into is concerned two parts.
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.
