Book Description
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.

Book Description
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.

Book Description
A comprehensive source of information on all aspects of shrimp production, this reference covers not only the global status of shrimp farming, but also examines shrimp anatomy and physiology. From nutrition to health management and harvesting issues to biosecurity, this well-researched volume evaluates existing knowledge, proposes new concepts, and questions common practices. With an extensive review on worldwide production systems, this compilation will be highly relevant to research scientists, students, and shrimp producers.

Book Description
Aquaculture production is expanding worldwide in both volume and scope, with a number of new species being introduced to aquaculture every year. Salmon Farming provides an overview of aquaculture production systems focusing on Atlantic salmon farming, which will enable users to: produce broodstock, juveniles and adult fish develop a production plan for juvenile and ongrowing farms evaluate and optimize the key working operations on juvenile and ongrowing farms identify the factors that are important for economic and sustainable production identify the factors that affect the rate of production, how these factors can be changed, and what effects such changes have adopt the best procedures for season-independent smolt production understand water quality requirements and evaluate the suitability based on water analysis prepare documents for production control and propose amendments prepare working plans for smolt production and ongrowing production farms establish maintenance routines/plans for smolt production and ongrowing production estimate the investment and running cost for the main components of smolt and ongrowing farms remain up to date with the laws and regulations that need to be considered in aquaculture production planning internationally stay abreast of new trends in the industry. Salmon Farming gives an overview of aquaculture production systems focusing on Atlantic salmon farming. However, much of the subject coverage and overall structure of the book are directly transferable to other species, with much of the core of the book being species-independent and applicable internationally. 5m Books

Book Description
Through coordination with other international development partners, including the United Nations Development Program, this report assesses a host of issues surrounding the introduction and successes of genetically improved farmed tilapia in several Asian nations. The institutional, socioeconomic, and environmental impact of genetically altered fish are all considered in the study's conclusions.
