Selective Breeding in Aquaculture: an Introduction
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 sa...
Selection and Breeding Programs in Aquaculture
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 f...
Genetics in Aquaculture III
The Third International Symposium on Genetics in Aquaculture was held in Trondheim, Norway in June, 1988 with 143 participants. The Institute of Aquaculture Research and the International Association for Genetics in Aquaculture were responsible for arranging the symposium. The symposium had three sessions with the topics Biotechnology, Breeding plans and New fish species. In the Biotechnology session, gene technology, and immunological aspects of disease resistance were reviewed, and it has been concluded that much knowledge has been accumulated in these fields in recent years and that large inputs in research will be necessary in coming years. With regard to breeding plans, the theoretical basis and the application of breeding schemes are discussed. Good possibilities for obtaining genetic change through breeding programmes have been demonstrated. For the future development of the aquaculture industry it is essential to have domesticated and productive organisms. Problems in farming marine fish species like halibut, cod and wolf-fish are also discussed.
Aquaculture development. 9. Development of aquatic genetic resources: A framework of essential criteria
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.
Entrepreneurship in Small Island States and Territories
Entrepreneurship in Small Island States and Territories is the first publication to consider the ‘creative’ side of enterprise in small island states and territories. Rather than playing out as remote, vulnerable and dependent backwaters of neo-colonialism, the world’s small island states and territories (with resident populations of less than 1 million) show considerable resourcefulness in facing up to the very real challenges of their predicament. The creative endeavours of their residents, facilitated by adroit public policy, has created economic and investment opportunities that translate into some private sector employment and decent livelihoods for many. Their ingenuity, coupled ...
Furunculosis
Furunculosis: Multidisciplinary Fish Disease Research presents a fascinating insight into the opinions and the controversies which have led to current knowledge of this disease. It is the first book to cover one single fish disease by presenting not just the reviews, but also critical examination of the progress made by various disciplines. The multidisciplinary approach of the book makes it a valuable guide for veterinarians, fisheries biologists, and fish farm managers, as well as an excellent instructional text for students. The volume explores current research strategies and projects what developments can be expected in each field. Considers the whole disease and not just the pathogen, Aeromonas salmonicida Analyzes the state of modern knowledge on the disease Suggests topics for future research and uses furunculosis as a model for other diseases Highlights and summarizes each section's themes and concepts Presents a unique compendium of research information for all professionals working on furunculosis
Improving Farmed Fish Quality and Safety
Global aquaculture production has grown rapidly over the last 50 years. It is generally accepted that there is limited potential to increase traditional fisheries since most fish stocks are well or fully exploited. Consequently increased aquaculture production is required in order to maintain global per capita fish consumption at the present level. Fish farming enables greater control of product quality and safety, and presents the possibility of tailoring products according to consumer demands. This important collection reviews safety and quality issues in farmed fish and presents methods to improve product characteristics.The first part of the book focuses on chemical contaminants, chemica...
