Download or read book Genetic Conservation of Salmonid Fishes written by Joseph G. Cloud and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.
Download or read book Evolution Illuminated written by Andrew P. Hendry and published by Oxford University Press, USA. This book was released on 2004 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work gives a critical overview on the evolution and population biology of salmon and their relatives. It should appeal to investigators in each of the scientific disciplines it integrates - evolutionary biology, ecology, salmonid biology, management and conservation. Variation in salmonids can be used to illustrate virtually all evolution.
Download or read book Fish Physiology Behaviour and Physiology of Fish written by Katherine A. Sloman and published by Gulf Professional Publishing. This book was released on 2005-12-13 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, behaviour and physiology have been considered two separate fields of biology with the majority of available literature focusing on one or the other. Recently the need for a multidisciplinary approach to these topics has been realised, highlighted by some of the sessions to be held at the 2003 annual meeting of the Society for Integrative and Comparative Biology such as 'regulation of behaviour' and 'mechanisms of behaviour'. The proposed volume aims to bring together these disciplines in a comprehensive review of the available literature. Fish Physiology: Behaviour and Physiology of Fish will be novel in actively bridging these two areas of fish biology together and considering them as inextricably linked. The progression of chapters focuses on different aspects of the life history of a fish, from predator avoidance through to reproduction, each written by scientists currently bridging the gap between behaviour and physiology in their own specialised subdiscipline. Multidisciplinary and integrative research in fish biology Written by internationally recognized researchers Encompasses the whole life span of fish A wide variety of inter-related topics presented in a cohesive format

Download or read book A Complex Culture of the British Columbia Plateau written by Brian Hayden and published by UBC Press. This book was released on 2011-11-01 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early hunter/gatherer societies have traditionally been considered basically egalitarian in nature. This assumption, however, has been challenged by contemporary archaeological and anthropological research, which has demonstrated that many of these societies had complex social, economic, and political structures. This volume considers two British Columbia Native communities -- the Lillooet and Shuswap communities of Fountain and Pavilion - and traces their development into complex societies. The authors explore the relation between resource characteristics and hunter/gatherer adaptations and examine the use of fish, animal, and plant species, documenting their availability and the techniques used in their gathering, processing, and storing. The book also shows how cultural practices, such as raiding, potlatching, and stewardship of resources, can be explained from a cultural ecological point of view. An important contribution to the study of hunting and gathering cultures in the Northwest, this book is the most detailed examination of the subsistence base of a particular hunting and gathering group to date. Its exploration of the reasons why complex hunting and gathering societies emerge, as well as the ecological relationships between cultures and resources, will make an important contribution to the study of cultural ecology and contemporary archaeology.
Download or read book The Behavior and Ecology of Pacific Salmon and Trout written by Thomas P. Quinn and published by UBC Press. This book was released on 2011-11-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.
