This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Pond Aquaculture Water Quality Management written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book Mechanics of Residual Soils Second Edition written by Geoffrey E. Blight and published by CRC Press. This book was released on 2012-05-03 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual soils are found in many parts of the world and are used extensively as construction materials for roads, embankments and dams, and to support the foundations of buildings, bridges and load-bearing pavements. The characteristics and engineering properties of residual soils can differ significantly from those of the more familiar transported soils. The fact that residual soils occur often in areas with tropical and sub-tropical climates and (extensively) in semi-arid climates, adds another dimension to their engineering performance, that of unsaturation. Although there are many books that deal with the mechanics of soils, these are based mainly on the characteristics and behaviour of saturated transported soils. The first edition of this book was the first book to be written specifically about the mechanics of residual soils. The book was prepared by a panel of authors drawn from the Technical Committee on Tropical and Residual Soils of the International Society for Soil Mechanics and Foundation Engineering. It was written as a practical professional guide for geotechnical engineers working with residual soils. The second edition has retained the valuable information contained in the first edition. The present editors and authors have extensively revised and augmented the content to bring it completely up to date, adding significantly to the sections on unsaturated soil mechanics and expanding the range and number of instructive case histories. Furthermore, sections on pedocretes, dispersive soils and karst have been added.

This book was released on 2013-02-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: My aim in this book is to give essential advice on all the main aspects of freshwater garden fish ponds. I have tried to include some of the science of ponds while keeping the information easy to understand. Each chapter begins with an outline of the main points of the topic. Each point is then expanded on.My experience with ponds has mainly been in the warm temperate climate in Perth, Western Australia. The principles for fish ponds are similar worldwide but warm temperate climates like that of Perth intensify some of the problems in ponds. This book will therefore be particularly useful to pond owners in sunny climates. The book begins with pond design, starting with the position of the pond in the garden. I discuss the consequences of different pond sizes and depths, and of natural and artificial ponds. I talk about the advantages of a dual pond system. I give guidelines for these and for self-cleaning ponds. I also say why I recommend designing the pond with a sump, overflow, leaf skimmer, and automatic top-up valve. Lastly, I give my colour preference for the pond bottom and sides. Next, I advise on pond construction. Ponds can be built with concrete, bricks, rigid polyethylene, fibreglass or liners. I write about my experiences with ponds made from each of these materials and also my preferences for pipework materials.In the following chapter, I recommend various pumps, filters (including ultraviolet clarifiers), water features, underwater lights and copper ionizers. Choosing the right equipment will give you the right effect for the lowest cost and for the least effort. The chapter on fish gives information on types of fish, especially goldfish and koi. I advise on when a new pond is ready for fish and on the number of fish a pond can support. I give information on the handling, transporting, and feeding of fish, and on diseases and predators.The next chapter delivers general information on water plants, why you should have them and their role in the ecology of the pond. Plants provide shade, oxygen, food, habitat and cover from predators. They filter toxins and excessive nutrients from the water. I give advice on keeping plants, including information on fertilizer and pests.Finally, I give recommendations for pond maintenance including a routine. My advice is directed at pumps, filters, pond cleanliness, exchanging water and maintaining the pH and hardness. The maintenance is largely directed at algae control. I discuss the various forms of nuisance algae and control methods for microalgae, blanket weed, and slime algae. Other advice includes information on water testing and water treatments. Maintaining good water quality is fundamental to the success of any fish pond. "Good" water quality means the water's suitability for its proposed purpose. Water quality is affected by every aspect of a pond, from its design and construction to its pumps, filters and maintenance. Each chapter of this book tells how each aspect of the pond affects the water. Every fish pond is different. The solutions to one pond's problems may be very different to another pond's.
