The fifth manual in the FAO Training Series on simple methods for agriculture. It deals with the practical aspects of management related to freshwater fish culture. This volume covers the management of earthen pond itself, showing how to improve and check water quality, how to control water loss and how to protect structure and fish stocks.
This manual deals in two volumes with the practical aspects of management related to freshwater fish culture in earthen ponds. The first volume (FAO Training Series No. 21/1, 1996, ISBN 92-5-102873-7, US$51.00) explains how to manage the pond itself. This second volume deals with how to manage fish stocks and, as a whole, a fish farm. Fish handling, propagation, feeding, harvesting, grading and storage are explained in simple terms, as well as the prevention and treatment of simple fish diseases and the monitoring of fish farm activities.
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).
Published in Cooperation with THE UNITED STATES AQUACULTURE SOCIETY The rapid growth of aquaculture worldwide and domestically has caused concerns over social and environmental impacts. Environmental advocacy groups and government regulatory agencies have called for better management to address potentially negative impacts and assure sustainable aquaculture development. Best Management Practices (BMPs) combine sound science, common sense, economics, and site-specific management to mitigate or prevent adverse environmental impacts. Environmental Best Management Practices for Aquaculture will provide technical guidance to improve the environmental performance of aquaculture. This book will be the only comprehensive guide to BMPs for mitigation of environmental impacts of aquaculture in the United States. The book addresses development and implementation of BMPs, BMPs for specific aquaculture production systems, and the economics of implementing best management practices. Written by internationally recognized experts in environmental management and aquaculture from academia, government, and non-governmental organizations, this book will be a valuable reference for innovative producers, policy makers, regulators, research scientists, and students.
Aquaculture Facilities and Equipment is a practical resource on the technical aspects needed for experts in the field to understand a high-performance aquaculture facility, its design and form, and the materials and systems used within the facility. The book is written at a level suitable for both field experts and students alike. It includes topics such as pond construction machinery, pumps for aquaculture, aeration for aquaculture, fish feeders, filtration systems in aquaculture, hatchery, raceways and tanks, and cage and pen culture. This book is based on 30 years of research that is presented as a useful reference to enhance efficient aquaculture production. It will be very helpful for experts working in related fields of fishery development and for those teaching fishery science and engineering courses. - Includes numerical equations for solving practical problems within an aquacultural facility - Combines knowledge of aquaculture science that is supported by relevant engineering inputs that boost production - Presents information on different types of traditional breeding, including hapa breeding, glass jar incubators, bundh breeding, induced carp breeding, hypophysation, and GnRH based inducing agents
