Genome Mapping And Genomics In Fishes And Aquatic Animals

Mapping of animal genomes has generated huge databases and several new concepts and strategies, which are useful to elucidate origin, evolution and phylogeny. Genetic and physical maps of genomes further provide precise details on chromosomal location, function, expression and regulation of academically and economically important genes. The series Genome Mapping and Genomics in Animals provides comprehensive and up-to-date reviews on genomic research on a large variety of selected animal systems, contributed by leading scientists from around the world. This volume summarizes the first era of genomic studies of aquaculture species, in which the tools and resources necessary to support whole-genome sequencing were developed. These tools will enhance efforts toward selective breeding of aquaculture species. Included in this volume are summaries of work on salmonids, cyprinids, catfish, tilapias, European sea bass, Japanese flounder, shrimps and oysters.

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.

Laboratory animals are those species that by accident of evolution, domestication and selective breeding are amenable to maintenance and study in a laboratory environment. Many of these species are studied as 'models' for the biology and pathology of humans. Laboratory animals included in this volume are sea-urchin, nematode worm, fruit fly, sea squirts, puffer fishes, medaka fish, African clawed frog, mouse and rat.

Genomics has revolutionized biological research over the course of the last two decades. Genome maps of key agricultural species have offered increased understanding of the structure, organization, and evolution of animal genomes. Building upon this foundation, researchers are now emphasizing research on genome function. Published with the World Aquaculture Society, Functional Genomics in Aquaculture looks at the advances in this field as they directly relate to key traits and species in aquaculture production. Functional Genomics in Aquaculture opens with two chapters that provide a useful general introduction to the field of functional genomics. The second section of the book focuses on key production traits such as growth, development, reproduction, nutrition, and physiological response to stress and diseases. The final five chapters focus on a variety of key aquaculture species. Examples looking at our understanding of the functional genomes of salmonids, Mediterranean sea bass, Atlantic cod, catfish, shrimp, and molluscs, are included in the book. Providing valuable insights and discoveries into the functional genomes of finfish and shellfish species, Functional Genomics in Aquaculture, will be an invaluable resource to researchers and professionals in aquaculture, genetics, and animal science.

Following the extremely well-received structure of the first edition, this carefully revised and updated new edition now includes much new information of vital importance to those working and researching in the fisheries and aquaculture industries. Commencing with chapters covering genetic variation and how it can be measured, the authors then look at genetic structure in natural populations, followed by a new chapter covering genetics in relation to population size and conservation issues. Genetic variation of traits and triploids and the manipulation of ploidy are fully covered, and another new chapter is included, entitled 'From Genetics to Genomics'. The book concludes with a chapter covering the impact of genetic engineering in aquaculture. With the inclusion of a wealth of up-to-date information, new text and figures and the inclusion of a third author, Pierre Boudry, the second edition of Biotechnology and Genetics in Fisheries and Aquaculture provides an excellent text and reference of great value and use to upper level students and professionals working across fish biology, aquatic sciences, fisheries, aquaculture, genetics and biotechnology. Libraries in all universities and research establishments where biological sciences, fisheries and aquaculture are studied and taught should have several copies of this excellent new edition on their shelves. Completely updated, revised and expanded new edition Subject area of ever increasing importance Expanded authorship Commercially useful information for fish breeders

From a global perspective aquaculture is an activity related to food production with large potential for growth. Considering a continuously growing population, the efficiency and sustainability of this activity will be crucial to meet the needs of protein for human consumption in the near future. However, for continuous enhancement of the culture of both fish and shellfish there are still challenges to overcome, mostly related to the biology of the cultured species and their interaction with (increasingly changing) environmental factors. Examples of these challenges include early sexual maturation, feed meal replacement, immune response to infectious diseases and parasites, and temperature and salinity tolerance. Moreover, it is estimated that less than 10% of the total aquaculture production in the world is based on populations genetically improved by means of artificial selection. Thus, there is considerable room for implementing breeding schemes aimed at improving productive traits having significant economic impact. By far the most economically relevant trait is growth rate, which can be efficiently improved by conventional genetic selection (i.e. based on breeding values of selection candidates). However, there are other important traits that cannot be measured directly on selection candidates, such as resistance against infectious and parasitic agents and carcass quality traits (e.g. fillet yield and meat color). However, these traits can be more efficiently improved using molecular tools to assist breeding programs by means of marker-assisted selection, using a few markers explaining a high proportion of the trait variation, or genomic selection, using thousands of markers to estimate genomic breeding values. The development and implementation of new technologies applied to molecular biology and genomics, such as next-generation sequencing methods and high-throughput genotyping platforms, are allowing the rapid increase of availability of genomic resources in aquaculture species. These resources will provide powerful tools to the research community and will aid in the determination of the genetic factors involved in several biological aspects of aquaculture species. In this regard, it is important to establish discussion in terms of which strategies will be more efficient to solve the primary challenges that are affecting aquaculture systems around the world. The main objective of this Research Topic is to provide a forum to communicate recent research and implementation strategies in the use of genomics in aquaculture species with emphasis on (1) a better understanding of fish and shellfish biological processes having considerable impact on aquaculture systems; and (2) the efficient incorporation of molecular information into breeding programs to accelerate genetic progress of economically relevant traits.

Genomics research on animals has generated huge databases and several new concepts and strategies, which are used to elucidate origin, evolution and phylogeny of species. Genetic and physical maps of genomes give details on chromosomal location, function, expression and regulation of genes. The series Genome Mapping and Genomics in Animals provides comprehensive and up-to-date reviews on genomic research on selected animal systems contributed by leading scientists from around the world. This volume offers information on gene mapping and genomics research in domesticated and farmed animals including cattle, water buffalo, sheep, deer, poultry, turkeys, rabbits, dogs and pigs. While the genome maps for some species are very limited, full genome sequences are available for cattle, chickens and dogs. Genomic research contributes to the identification of genetic regions that control the functionality and well-being of animals. Several farmed species are also used as models for biomedical studies.
