Salmonid Culture

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.

Salmonids represent the primary coldwater fishes of culture interest in the world today; species discussed in this work were selected on the basis of their importance to the aquaculture community. In recognition of the growing concern that aquaculture development has the potential to negatively impact the natural environment, a chapter on controversies surrounding salmonid culture has been included. The first chapter provides a summary of life history information of the species covered in the book.

Culture of Nonsalmonid Freshwater Fishes, 2nd Edition presents an expanded, updated description of important techniques and practices for the culture of some of the most widely cultured nonsalmonid species used for human consumption (channel catfish, tilapia, carp) for stocking freshwater bodies for recreational fishing (bass, walleye, striped bass), and for bait (minnows). This new edition features the latest information on spawning, nutritional requirements, special culture requirements, tolerance to various water quality parameters, and types of diseases that can occur. It is an essential book for all aquaculturalists, agency fishery biologists, and students interested in freshwater aquaculture.

This is the first comprehensive collection of molecular techniques for diagnosing diseases important in the culture and conservation of salmonid fish. It brings together leading authors in this rapidly growing field and provides an overview of the present state of the art from the perspective of practical application of these methods in diagnostic laboratories. This book will serve as a useful handbook for diagnosticians and researchers involved in fish disease, particularly laboratories establishing these new diagnostic tests for the first time, and provides valuable background information on many of the diseases and their causative organisms.

The problem is that, with the continuing degradation of water and habitat quality, selective harvesting, genetic enhancement programs, and the introduction of hatchery fish into wild populations, the genetic makeup of fish is changing radically. In 27 papers from a workshop held in Moscow, Idaho, an

This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.
