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.

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 Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 913 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

This book was released on 2019-03-13 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic genetic resources play a crucial role in contributing to global food security and nutrition, as well as to sustainable livelihoods. However, in various international fora, FAO Members have highlighted the limitations and constraints that they face in assessing their national capacities to use, manage and conserve such resources as well as in identifying and monitoring the resources used. The main issues are limited information, inadequate national capacities and expertise, and inadequate legislation and policy frameworks. In recognition of these needs, this framework is a guideline that FAO and FAO Members can use to evaluate the capacities, infrastructures and governance tools of a country regarding the sustainable use of aquatic genetic resources. It will be of use to fish farmers, hatchery people, fisher folk, aquatic genetic resource managers, policy-makers, decision-makers, donors, consumers and academia.

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 2005-07-10 with total page 364 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 Blue Genes written by Brian Harvey and published by Taylor & Francis. This book was released on 2013-06-17 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advance of genetic sciences has led to a 'blue revolution' in the way we use aquatic biodiversity. By 2020, the world will be eating almost as much farmed as wild fish, marine bacteria could yield the cure for cancer and deep-sea bacteria may be exploited to gobble up oil spills. Science is moving ahead at a staggering speed, and the demand for genetic resources is growing rapidly - yet governance and policy lag far behind. This groundbreaking work is the first to look at the ownership, governance and trade in aquatic genetic resources. Blue Genes describes the growing demand for aquatic genetic resources and the desperate need to fill the policy vacuum about the management and conservation of aquatic biodiversity, which would help create a foundation for rules dictating access to, and use of, aquatic genetic resources. Special attention is paid to indigenous and local people having the right to access these resources and their role in managing and conserving aquatic biodiversity. The book concludes with policy recommendations specifically tailored to aquatic resources, with the use of six case studies from four continents to illustrate key issues.

Download or read book Species and System Selection for Sustainable Aquaculture written by PingSun Leung and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published in Cooperation with THE UNITED STATES AQUACULTURE SOCIETY As aquaculture production continues to grow and develop there is a continuous search for new species to culture to be able to fully exploit new national and international markets. Species selection for aquaculture development often poses an enormous challenge for decision makers who must decide which species and culture technologies to support with public resources, and then how best to divide those resources. Species and System Selection for Sustainable Aquaculture brings together contributions from international experts with experience in identifying potential species and production systems for sustainable aquaculture with a socioeconomic focus. The book is divided into three sections: Principles, Practices, and Species-Specific Public Policy for Sustainable Development. An outgrowth of a workshop held as part of the Aquaculture Interchange Program with examples from around the globe carefully edited by PingSun Leung, Pat O'Bryen, and Cheng-Sheng Lee this volume will be an important reference for all researchers, professionals, economists, and policy-makers involved in selecting new species for the development of sustainable aquaculture.

Download or read book Changing the Face of the Waters written by World Bank and published by World Bank Publications. This book was released on 2007-06-27 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture the farming of fish and aquatic plants has become the world's fastest-growing food production sector, even as the amount of wild fish caught in our seas and freshwaters declines. From fish foods and pharmaceuticals to management of entire aquatic ecosystems, acquaculture is truly changing the face of the waters. Increased growth, however, brings increased risk, and aquaculture now lies at a crossroads. One direction points toward the giant strides in productivity, industry concentration, and product diversification. Another direction points toward the dangers of environmental degradation and the marginalization of small fish farmers. Yet another direction invites aquaculture to champion the poor and provide vital environmental services to stressed aquatic environments. 'Changing the Face of the Waters' offers a cutting-edge analysis of the critical challenges facing aquaculture, balancing aquaculture's role in economic growth with the need for sound management of natural resources. The book also provides guidance on sustainable aquaculture by evaluating alternative development pathways, placing particular emphasis on the application of lessons from Asia to Sub-Saharan Africa and Latin America. Aimed at policy makers, planners, and scientists, this book provides a comprehensive frame of reference for orienting ideas and initiatives in this dynamic industry.

This book was released on 2010-01-01 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world has made enormous progress in the past 50 years toward eliminating hunger and malnutrition. While, in 1960, roughly 30 percent of the world's population suffered from hunger and malnutrition, today less than 20 percent doessome five billion people now have enough food to live healthy, productive lives. Agricultural development has contributed significantly to these gains by increasing food supplies, reducing food prices, and creating new income and employment opportunities for some of the world's poorest people.This book examines where, why, and how past interventions in agricultural development have succeeded. It carefully reviews the policies, programs, and investments in agricultural development that have reduced hunger and poverty across Africa, Asia, and Latin America over the past half century. The 19 successes included here are described in in-depth case studies that synthesize the evidence on the intervention's impact on agricultural productivity and food security, evaluate the rigor with which the evidence was collected, and assess the tradeoffs inherent in each success. Together, these chapters provide evidence of "what works" in agricultural development.
