Über diesen Titel

Inhaltsangabe

The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.

Von der hinteren Coverseite

This book provides a basic introduction to selective breeding in aquatic species, and describes the concepts behind establishing and running successful breeding programs. Although only 10% of world aquaculture production is currently based on genetically improved stocks, the dramatic gains achieved in species such as Atlantic salmon and tilapia serve to demonstrate the potential of selective breeding to improve growth, product quality, disease resistance and other commercially important traits. As increasing pressure is placed on feed, land and water resources, there is a growing need for such programs to be implemented on a large scale in aquaculture.

The major objective of this book is to introduce selective breeding to a wider audience, using results of numerous studies to show that the high fecundity and genetic variation in most aquatic species can lead to rapid and dramatic improvements. Building on well-established methods based on quantitative genetic theory, the key role that molecular genetics will play in the future of aquaculture breeding is also discussed.
