Selective Breeding in Aquaculture: an Introduction by Trygve Gjedrem,Matthew Baranski Pdf

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.

Selection and Breeding Programs in Aquaculture by Trygve Gjedrem Pdf

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.

Organic Aquaculture by Giuseppe Lembo,Elena Mente Pdf

This book addresses, reviews and evaluates key themes in organic aquaculture and is set out to show how these relate to the challenges and bottlenecks for a responsible organic aquaculture production in Europe. The key themes reflect the main challenges facing the organic aquaculture industry: guarantee and certification system, nutrition, reproduction, production system design and animal welfare. In addition, it assesses the impact of new and future potential development of new knowledge to update and modify the criteria and standards for organic aquaculture. Organic aquaculture is an alternative production approach driven by the growing interest in sustainable utilization of resources. It is rightly viewed as an important contributor to the economy and to the well-being and health of communities. This work will contribute to the scientific knowledge that needs to strengthen effective organic aquaculture. The collation of information on research and data will be of applied value to researchers, university students, end users and policy authorities in the EU and worldwide.

Introduction to the General Principles of Aquaculture by Hans Ackefors,Jay Huner,Mark Konikoff Pdf

Introduction to the General Principles of Aquaculture provides novice aquaculturists with an overview of the aquaculture industry so you may proceed successfully in academic studies or commercial ventures. The authors furnish you with insight into the history and development of aquaculture and cover the subjects of natural production versus aquaculture, the aquatic environment, energy requirements of and relationships in aquaculture systems, important components of aquaculture systems, selection of aquaculture species, major cultured species and their distribution, global aquaculture production, a comparison of agriculture and aquaculture, and those factors promoting and constraining aquaculture. The book is liberally illustrated so that students and laymen are able to visualize systems and species. Furthermore, tables and figures are used throughout to emphasize important points, facts, and methods. As an introductory text, it emphasizes several aspects of aquaculture that must be understood by those new to the industry. These aspects include water quality, species of importance around the world, and current and projected aquaculture production on a global basis. The important components of any aquaculture system are also covered in some detail--biological factors, technical-biological factors, technical-economic factors, production cost factors, socioeconomic factors, and species selection factors. Laypersons considering aquaculture as an investment and students considering aquaculture as a career, but who have no real background in agriculture and fisheries sciences,will find this book to be a key information source. Introduction to the General Principles of Aquaculture is written with the global market in mind and instructors will find it to be a useful introductory text at the undergraduate level.

Genetics in Aquaculture V by Roger W. Doyle Pdf

This book is based on the Fifth International Symposium on Genetics in Aquaculture which was held in Halifax, Canada,in June 1994.There was a noticeable change in emphasis in the contributions to this meeting: fewer quantitative genetics and selective breeding papers than before, more papers dealing with molecular genetics and transgenics. As the latter approaches show solid evidence of their importance to aquaculture, their political and environmental ramifications are coming to the fore and several papers presented at the symposium addressed these issues. The contributions also reflected broad new environmental concerns about the genetic interaction between aquaculture and wild aquatic populations.The papers selected for publication underwent rigorous peer review and, for reasons of space, selection intensity had to be rather high. A number of worthy papers could not be accommodated and not all abstracts could be included in this proceedings volume.

Aquaculture in China by Jian-Fang Gui,Qisheng Tang,Zhongjie Li,Jiashou Liu,Sena S. De Silva Pdf

Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.

The State of the World’s Aquatic Genetic Resources for Food and Agriculture by Food and Agriculture Organization of the United Nations Pdf

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.
