Book Description
As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

Book Description
This important title encompasses features of genetic processes in complexly organised population systems of salmonids, one of the most commercially valuable families of fish worldwide. Translated from the original work in Russian, the authors have taken the opportunity to update and revise the work, much of it appearing in the English language for the first time. Covering such important concepts as optimal gene diversity and the unfavourable influence of fishery and hatchery reproduction on the genetic structure of salmon populations, the authors have drawn together a huge wealth of information that will form the cornerstone of much new work in the future. The authors of Salmonid Fishes have between them many years of research experience and practical knowledge in the area and the English translation of this important work, which has been edited by Professor John Thorpe and Professor Gary Carvalho, provides vital information for all those involved in salmonid management, exploitation and conservation, including fish biologists, fisheries managers, conservation and population biologists, ecologists and geneticists.

Book Description
Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Book Description
As the human population increases and nations become more industrialized, the habitat and water quality required for the survival of fish continues to decline. In addition to these environmental factors, fish populations are directly or potentially affected by harvesting, enhancement programs and introgression with hatchery-propagated or transgenic fish. To our knowledge no other scientific meeting has been assembled to consider the breadth of the problem, to review the technology that is presently available for the preservation of the germ plasm of salmonid stocks and to identify the scientific advances that are required to overcome the problems. Because many salmonids have spawning grounds within the confines of a specific region or county but will spend a large portion of their life cycle within the territorial waters of other countries or in the open ocean, the preservation of unique genes or gene pools in these animals requires international cooperation. This scientific meeting has provided a forum in which to discuss the problems, evaluate the present methods or technology for addressing the problems and suggest new directions or innovations that need to be implemented. During this meeting we limited our discussion to salmonid fishes. However, the general conclusions about the factors that affect the population dynamics of fish stocks and the technical aspects concerning the preservation of germ plasm will be applicable to other fish species.

Book Description
This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.

Book Description
Cleaner fish are increasingly being deployed in aquaculture as a means of biological control of parasitic sea lice, and consequently the farming of wrasse and lumpfish, the main cleaner fish species in current use in salmon farming, is now one of the fastest expanding aquaculture sectors with over 40 hatcheries in Norway alone. Cleaner Fish Biology and Aquaculture Applications reviews and presents new knowledge on the biology of the utilised cleaner fish species, and provides protocols in cleaner fish rearing, deployment, health and welfare. The latest knowledge is presented on specialist technical areas such as cleaner fish nutrition, genetics, health, immunology and vaccinology, welfare, transport and fisheries. Specific chapters detail cleaner fish developments in the main salmon-producing countries. Contributions from over 60 leading researchers and producers give an exciting mix of information and debate. The book comprehensively addresses the questions of sustainability of cleaner fish use in aquaculture, bottlenecks to the optimum production of cleaner fish, and improvements and best practice in on-farm deployment methods, for optimum survival and enhanced welfare of cleaner fish. Some of the key features of this important book: Provides a comprehensive review of the latest globally-available information on the use of cleaner fish under one cover Highlights and addresses the main issues in the farming of cleaner fish, and provides guidance on how to improve growth and survival Identifies issues in the farm application of cleaner fish and provides details on how to address these issues Written by a team of internationally-recognised experts in cleaner fish biology, culture and deployment Cleaner Fish Biology and Aquaculture Applications is an essential purchase for hatchery managers, salmonid producers, fish farm operatives, researchers, regulators, students and enthusiasts working with, and interested in, cleaner fish. Personnel within companies supplying equipment and services to the aquaculture industry, and libraries in all universities and research establishments where biological sciences and aquaculture are studied and taught should have copies of this landmark publication. 5m Books
