In this book, numerous prominent aquaculture researchers contribute 27 chapters that provide overviews of aquaculture effects on the environment. They comprise a comprehensive synthesis of many ecological and genetic problems implicated in the practice of aquaculture and of many proven, attempted, or postulated solutions to those problems. This is an outstanding source of reference for all types of aquaculture activities.

The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.

Many authors of this new book were participants at the workshop on diapause in aquatic invertebrates (Pallanza, Italy 2003). The book consists of two major parts indicated in its title: Phenomenology of diapause and significance of this adaptation in scientific and practical uses. Cultivation of live food, like rotifers or Artemia is an expanding application of practical use of diapause in modern aquaculture. Diapause provides the advantage of promoting the colonization of new environments by facilitating the passive transport of the resting stages of invasive species. Creation of artificial ecosystems outside the Earth's biosphere with using dormancy becomes an actual possibility with the plans of humans to colonize our nearest planets. Studies on the vertical distribution of resting eggs in sediment cores yield important ecological information.

This book is an up-to-date discussion of the culture of striped bass and other "Morone" spp. The subject matter is broken down into functional components of the spawning, husbandry, and economics of the industry, and is written by some of the leading scientists in each of the respective areas of discussion. The chapters on reproduction, nutrition, environmental requirements, transportation, economics and fish processing are not found anywhere else in the striped bass literature. The chapter on water quality takes a very non-traditional approach to considering the impact water quality has on the production success of "Morone" and offers some very thought-provoking ideas on water management.

Primarily written as a reference work, this book is intended to complement existing technique manuals.

The book covers various biotechnological research efforts and their applications in fisheries and aquaculture, especially in the area of fish breeding, health management, nutrition and culture. Application of the recent biotechnological tools, like Transcriptomics, Transgenesis, Nanotechnology, Metabolomics, RNAi and CRISPRi Technologies in the field of fisheries research are included in the book. Topics like conservation genetics for management of fishery resources are also covered in the book. It aims at addressing the growing need of the biotechnology in advancing the cause of aquaculture with a view to provide food and nutritional security to the world. This book will be of immense use to teachers, researchers, academicians, development officials and policymakers, involved in R&D of fisheries and aquaculture sectors. Also, the book serves as an additional reading material for undergraduate and graduate students of fisheries, marine sciences, ecology, aquaculture, and environmental sciences. The research in aquaculture biotechnology is likely to have significant impact on aquaculture and fisheries by way of supporting nutritional food security to the growing population.

Aquaculture is rapidly becoming a major source of fish protein used to meet the nutritional needs of humans. As the aquaculture industry grows, exposure of farmed fish to environmental contaminants, and the need for chemical therapeutic agents for fish, will increase. This book is designed to bring together authorities worldwide on the regulation of environmental contaminants and food chemicals and researchers investigating the metabolism and disposition of foreign chemicals (xenobiotics) in fish species.

These proceedings of a workshop of the International Association for Phytoplankton Taxonomy and Ecology are directed specifically at the relationship between phytoplankton ecology and the trophic status of water bodies. Contributions address the fact that distinctive assemblages of phytoplankton species are closely associated with particular categories of water bodies. Particular attention is paid to how communities are assembled and to the ways in which environmental constraints filter the successful species. Overview articles are included. The book will be a valuable source of information to limnologists, algologists, and the technical staff of all water suppliers.

Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.

A topical and authoritative examination of the current crisis in the fishing industry, offering a political analysis of the reasons for the crisis and suggesting ways in which this might be overcome. The contributors include fishery officials and scientists as well as academics. The focus is mainly on the European fishing industry, with issues including political bargaining in the EU, the working of quota arrangements, the status of marine scientific knowledge and the industry's management structures in different countries.

As aquaculture continues to expand there is a need for greater knowledge of medicinal treatments both for the prevention and treatment of disease and for the economic husbandry of fish. This book, the first of its kind, is written for a worldwide readership. It is a reference manual for anyone involved in the selection of medicines for administration to fish. It will also be useful to administrators concerned with the legal control of aquaculture. The first part covers issues which affect all medicine's methods of administering drugs to fish, the various aspects of safety and the relevant legislation in countries with important aquacultural industries. Subsequent parts review the range of available medicinal substances and present current knowledge of the pharmacology and methods of use for each. Particular attention is given to safety issues - for the fish, for the person administering the medicine, for the consumer of medicated fish and for the environment.

Over the last decade, interest in seafood products has grown dramatically. The increasing level of consumer interest has resulted in a proliferation of research initiatives to understand the unique properties of seafoods. Microbiology is only one of the scientific disciplines involved in seafood research, but it is fundamental to understanding the quality and safety issues that are important to the seafood industry and consumers. The purpose of this book is to survey the microbiological characteristics associated with many of the major seafood commodities and the changes in the microflora as a result of processing, distribution and storage.

Shrimps are subject to great consumer demand in the United States. However, more than #1 billion worth of shrimp is now imported; more than twice the amount produced domestically. Domestic shrimp production, mostly from the trawler fleet in the Gulf of Mexico, is thought to be at its maximum sustainable yield of 91,000 MT (heads-off). Increased production of shrimp in the U.S. through mariculture has been motivated by the increasing demand for this product.
The biology of penaeid shrimp and lack of technology for their culture present special problems in fisheries science, reproductive biology, endocrinology, nutrition, pathology, culture science and future research. The purpose of the Frontiers of Shrimp Research symposium was to assess the status of shrimp research in these areas and to further foster the scientific collaboration vital for significant research advances. The participants included representatives of the science funding agencies, the mariculture industry and representatives of both the scientific research and science policy communities.
The subject matter should be of interest to a variety of readers. Advanced undergraduate/graduate students, mariculturists and research workers will find this volume both interesting and informative.

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)."
