Handbook For Aquaculture Water Quality

The revised second edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. This book presents the basic aspects of water quality, emphasizing physical, chemical, and biological factors. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

Annotation Aquaculture provides an attractive alternative to capture fisheries where the majority of species are overexploited and an increased yield potential is unlikely. This document reviews the standards for water and fish product quality, looks at the parameters of greatest importance to aquaculture, and discusses the scientific basis for these standards. Containing information from current literature and government standards, it provides practical, cost-effective guidelines to determine whether the quality of the proposed source water will present a significant risk to the success of a project.

This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality.

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).

The Second Edition of the CRC Handbook of Mariculture provides an extensive comparison of marine shrimp culture techniques from around the world. This extensively revised and updated Second Edition focuses on growout systems that have contributed to the production success of shrimp farms and systems worldwide. Topics covered include methods for the culture and preparation of algae, rotifers, Artemia, and other foodstuffs for use in crustacean farms; recent developments on enriching larval food organisms to improve crustacean diets; conditioning and spawning penaeid shrimp; obtaining and manipulating shrimp eggs and sperm for controlled reproduction and use of intensive nursery raceways for juvenile shrimp production; and discussions of many types of marine shrimp growout systems. In addition, culture systems used in Hawaii, Ecuador, Taiwan, and Japan are described in detail. Significant new information from Japan on hormonal control of penaeid shrimp maturation and spawning is discussed. Marine shrimp and Macrobrachium shrimp diseases by the foremost authorities in the area are presented with detailed photographs and illustrations to help identify diseases. The book also includes an update on American lobster larval and juvenile culture.

Discusses how to successfully farm 35 food fishes. Written for professionals and amateurs, the text covers general and scientific aspects of aquaculture; integrating systems with plants, land animals, and cage cultures; pond construction; water chemistry; marketing and shipping concerns; diseases; and regulations. Throughout, an emphasis is placed upon efficiency and working with natural ecosystems. Annotation copyrighted by Book News, Inc., Portland, OR
