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 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
Cryopreservation of gamete is widely used in artificial insemination of cattle, horse, pig, sheep and poultry, and has resulted in upgrading the genetic potentials of native stocks. Similarly, cryopreservation of gamete can be potentially applied in fish breeding and aquaculture. Cryopreservation of gamete is an effective way to preserve the gene pool of cultured species and to conserve the biodiversity. Given that many fish species are now threatened or endangered, it is imperative to establish a regional fish germplasm repository to preserve the vanishing genetic materials as well as to conserve the existing gene pool. Cryopreservation appears one of the most effective ways to preserve the existing gene pool; however, preservation of fish ova has not been possible yet. On the other hand, domestication of a species over many generations normally results in changes in genetic materials. Cryopreservation of spermatozoa can be used as a very effective tool for conserving the genetic materials and to prevent gene introgression. This book summarizes the methodological aspects of cryopreservation and its application in conserving the gene pool of commercial carp, silver carp.
