Available in PDF, EPUB and Kindle. Book excerpt: Growth rate is a primary trait of interest in most finfish selection programs and is intrinsically linked to productivity and profitability of finfish aquaculture industry in several parts of the world. Search for candidate genes influencing growth has been a major focus of research in aquaculture and several such genes have been isolated from the fish genome and their effects are quantified. Growth hormone genes have been studied extensively in many species because of its potential in enhancing the growth rate of fishes in aquaculture. The identified growth hormone gene in most of the fishes is roughly 1.5 kb long, with the protein coding region divided in to four to five blocks (exons) representing less than one third length of the genomic region. Growth hormone (GH) is a single chain polypeptide that plays a major role in the growth development of vertebrates. It is the main regulator of postnatal somatic growth and stimulates anabolic processes such as cell division, skeletal growth and protein synthesis. In addition, growth hormone is also involved in the regulation of fat oxidation, inhibition of glucose transport to peripheral tissues and regulation of ribosome translational activity, which in turn influences protein synthesis. Presently, the importance of GH as a candidate gene for studies of genetic variation in connection with growth traits and potential natural marker for studies of evolutionary relationship of various fishes has been demonstrated. Its potential application in the growth traits and fish evolution studies has been an active area of research. Natural growth rates of organisms have evolved to provide maximum fitness in wild environments and therefore, enhancement of natural growth rate of fish in aquaculture has been extensively explored, with gains arising from improvements in husbandry, nutrition, and genetical selection. Growth enhancement can be advantageous for aquaculture by shortening production time, and enhancing feed conversion efficiency. Therefore, endocrine approaches in controlling growth have been extensively explored. Several studies have demonstrated the efficacy of mammalian GH in the acceleration of growth of various species. In fish, GH administration by various modes of delivery like injection, and oral administration of hormones has been successfully studied. These studies have suggested that the exogenous growth hormone enhances fish growth by stimulating appetite and improving feed conversion. It is clearly understood that growth hormone plays major role in aquaculture industry by increasing the growth. Therefore, knowing the different aspects of growth hormone is very much essential for the researchers aim for growth enhancement in fishes.

Download or read book Growth Hormone in Adults written by Anders Juul and published by Cambridge University Press. This book was released on 2000-04-27 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: This revised new edition reviews the substantial advances in our understanding of the vital role of growth hormone (GH) in maintaining adult health, and the resulting disorders from GH deficiency. The first edition, published in 1996, provided a pioneering overview of the subject; this new edition provides an even more comprehensive account, fully updated with the latest research, clinical applications, and references. The therapeutic benefits of GH treatment in GH deficiency are thoroughly evaluated, including effects on metabolism, cardiac function, exercise performance, psychosocial aspects, and aging and gender-specific effects. This compilation by the world's leading experts covers clinical investigation, diagnosis and treatment issues, and encompasses new knowledge of the control and action of GH secretion. This volume is the most authoritative, comprehensive, and detailed account available and will be an essential source of reference for all endocrinologists.

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Book Synopsis Hormones and Their Receptors in Fish Reproduction by : Philippa Melamed
Download or read book Hormones and Their Receptors in Fish Reproduction written by Philippa Melamed and published by World Scientific. This book was released on 2005 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on the molecular aspects of fish reproduction has progressed swiftly over the past few years. With the availability of wide-ranging molecular tools, fish researchers have elucidated many of the molecular mechanisms regulating reproduction which operate in the brain, pituitary and gonad. This research has revealed novel variants of reproductive hormones and their receptors, and has shed new light on the mechanisms through which many of these genes can be activated. Several of the findings, which are reported in this book, have formed the basis for subsequent mammalian research and will also constitute the platform on which new approaches to reproductive management in aquaculture can be developed.

Available in PDF, EPUB and Kindle. Book excerpt: The First Asia --- Pacific Conference on Agricultural Biotechnology was held in Beijing, China on 20-24, August, 1992. Over half the population in the world is in the Asian and Pacific Region. With an increasing population and decreasing farming lands, it is important to develop agricultural biotechnology for improvement of the productivity, profitability and stability of the farming system. The Conference's main objectives were to bring together scientists working in different fields of agricultural biotechnology to stimulate discussion on this important process and to have an appraisal of the most recent studies concerning genetic manipulation of plants, plant cell and tissue culture, plant gene regulation, plant-microbe interaction, animal biotechnology etc. The Conference was attended by 391 scientists from different countries and regions. This volume presents the contributions of the lectures and a selected number of posters, which are an up-to-date account of the state of knowledge on agricultural biotechnology. The book provides a valuable reference source not only for specialists in agricultural biotechnology, but also for researchers working on related aspects of agronomy, biochemistry, genetics, molecular biology, microbiology and animal sciences. It is with great pleasure to acknowledge the contributions of the authors in assuring the prompt publication of this volume. We would also extend our sincere thank to Kluwer Academic Publishers for the publication of these proceedings.
