This book was released on 2010-03-17 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Selection and Breeding Programs in Aquaculture written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2005-04-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.

Download or read book The State of the World s Aquatic Genetic Resources for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.

Download or read book Aquatic Genomics written by N. Shimizu and published by Springer Science & Business Media. This book was released on 2003-01-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a scientific pursuit there is continual food for discovery and wonder. M. Shelley (1818) Genomic analysis of aquatic species has long been overshadowed by the superb activity of the human genome project. However, aquatic genomics is now in the limelight as evidenced by the recent accomplishment of fugu genome sequencing, which provided a significant foundation for comparative fish genomics. Undoubt edly, such progress will provide an exciting and unparalleled boost to our knowl edge of the genetics of aquatic species. Thus, aquatic genomics research has become a promising new research field with an impact on the fishery industry. It is notewor thy that the Food and Agriculture Organization (FAO) of the United Nations has projected that current global fisheries production will soon become insufficient to supply the increasing world population and that aquaculture has a great potential to fulfill that demand. This book, Aquatic Genomic. ~: Steps Toward a Great Future, was designed as a collection of advanced knowledge in aquatic genomics and biological sciences. It covers a variety of aquatic organisms including fish, crustaceans, and shellfish, and describes various advanced methodologies, including genome analysis, gene map ping, DNA markers, and EST analysis. Also included are discussions of many sub jects such as regulation of gene expression, stress and immune responses, sex differ entiation, hormonal control, and transgenic fishes.
Download or read book Molecular Genetics in Fisheries written by Gary R. Carvalho and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic principle of all molecular genetic methods is to employ inherited, discrete and stable markers to identify genotypes that characterize individuals, populations or species. Such genetic data can provide information ori the levels and distribution of genetic variability in relation to mating patterns, life history, population size, migration and environment. Although molecular tools have long been employed to address various questions in fisheries biology and management, their contributions to the field are sometimes unclear, and often controversial. Much of the initial impetus for the deployment of molecular markers arose from the desire to assess fish stock structure based on various interpretations of the stock concept. Although such studies have met with varying success, they continue to provide an impetus for the development of increasingly sensitive population discriminators, yielding information that can be valuable for both sustainable exploitation and the conservation of fish populations. In the last major synthesis of the subject, Ryman and Utter (1987) summarized progress and applications, though this was prior to the wide-scale adoption of DNA methodology. New sources of genetic markers and protocols are now available, in particular those that exploit the widely distributed and highly variable repeat sequences of DNA, and the amplification technique of the polymerase chain reaction.
