Genetic Conservation of Salmonid Fishes

Pages : 312
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.

Aquaculture Management
Author: James W. MeadePublisher: Springer Science & Business Media
ISBN: 1461564700
Category : Science
Languages : en
Pages : 184
Book Description
Although some nations, such as Japan, have invested in aquaculture research and developed major aquaculture industries, the opportunities for similar devel opment in the United States remain largely unnoticed. In a typical recent year the United States, which claims 20% of the world's marine fisheries resources, imported seafood worth $4. 8 billion and exported $l. 3 billion. In addition to the $3. 5 billion deficit in food-fish, was another $2. 7 billion deficit for nonedible fishery products. Next to oil, fishery products constituted the second highest drain on the United States balance of payments and accounts for a significant portion of the foreign trade deficit. Furthermore, fish consumption has been increasing in North America. In response to the demand for fishery products, aquaculture managers not only have the opportunity to realize economic profit, but in doing so can make an important contribution to reducing the national debt, providing employment, and enhancing our diet. This book might be considered a farm management text for those in aquaculture. It is intended to provide an introduction to aquaculture principles and an introduction to management, including business and people management, microeconomics, and the concepts of efficiency and productivity. I hope it will bridge the gap between conservationists, the academic community, and commer cial culturists. Abundant references should enable the reader to quickly access literature on most topics germane to the management of culture systems.
Principles of Salmonid Culture
Author: W. PennellPublisher: Elsevier
ISBN: 0080539661
Category : Science
Languages : en
Pages : 1071
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.
