Download or read book ASSESSMENT OF MAJOR FACTORS AFFECTING TRIPLOID INDUCTION USING HYDROSTATIC PRESSURE AND GROWTH ASSESSMENT OF TRIPLOID EASTERN OYSTERS CRASSOSTREA VIRGINICA WITHIN THE BRAS D OR LAKE written by Ian Sewell and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Triploid oysters can be created through chemical or pressure treatments that induce a diploid embryo to become a triploid by blocking the expulsion of a polar body during development. Triploid oysters are desirable because they are sterile, faster growing, and have more energy to fight pathogens. Little is known about triploid induction in the Eastern oyster using hydrostatic pressure. The focus of these experiments were to evaluate different variables to elucidate their impact on triploid induction and assess the growth of triploid Eastern oysters grown in Canadian waters. The first objective of this study was to determine the most efficient pressure intensity and duration treatments that would yield the highest triploidy induction rates in the Eastern oyster. The second objective was to compare the growth of triploid vs diploid oysters in field conditions in the Bras d'Or lake, Nova Scotia.
Download or read book Aquaculture and Fisheries Biotechnology written by Rex A. Dunham and published by CABI. This book was released on 2023-02-28 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic improvement of fish for aquaculture and related fisheries has seen huge advances over recent years. Building upon the previous two editions of Aquaculture and Fisheries Biotechnology: Genetic Approaches, this 3rd edition offers a presentation of traditional selective breeding, modern genetic biotechnology, genomics, gene transfer and gene editing, and the latest developments in genetic biotechnology such as epigenetics, xenogenesis and genome-wide association study coupled with commercial application, the impact of government regulation and expectations for the future. It provides a firm grounding in relevant aspects of classical genetics, before focusing on particular aspects such as sex reversal and breeding as applied in aquaculture and fisheries. It also explores how more recent molecular genetics, genomics and biotechnology techniques can be used and combined in improvement programmes for fish and aquaculture species. A glossary explains the latest terminology used in biotechnology and genetics. This book will be useful for research scientists and students in marine biotechnology, aquaculture biotechnology, and fish genetics and breeding.

Download or read book Aquatic Genomics written by N. Shimizu and published by Springer Science & Business Media. This book was released on 2003-01-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Tilapia written by Carl D Webster and published by CRC Press. This book was released on 2006-08-21 with total page 705 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn to maximize tilapia production in different areas around the world Tilapia is the second-most cultured fish species in the world, and its production is increasing each year. However, for several reasons profit margins remain slim. Tilapia: Biology, Culture, and Nutrition presents respected international experts detailing every aspect of tilapia production around the world. Biology, breeding and larval rearing, farming techniques, feeding issues, post-harvest technology, and industry economics are clearly presented. This concise yet extensive reference provides the latest research and practical information to efficiently and economically maximize production in diverse locales, conditions, and climates. Tilapia: Biology, Culture, and Nutrition comprehensively explores all types of tilapia with a detailed biologic description of the fish that takes readers from egg through harvesting. The book authoritatively discusses production issues such as feed nutrition, temperature, water quality, parasites, and disease control to guide readers on how to best encourage fast, efficient growth. Economic and marketing information are examined, including industry data and projections by country. Each chapter approaches a specific facet of tilapia and provides the most up-to-date research available in that area. This resource gives the most current, detailed information needed for effective tilapia farming in one compact economical volume. Extensively referenced with an abundance of clear, helpful tables, photographs, and figures. Tilapia: Biology, Culture, and Nutrition discusses in detail: complete biology, including sex ratios, optimum temperatures for growth and spawning, water quality parameters, and disease tolerance industry predictions hormonal control of growth genetic improvement sex determination, manipulation, and control seed production culture practices earthen and lined pond production culture in flowing water cage culture feed formulation and processing, and feeding management soil, water, and effluent quality saline tolerance levels with optimum rate of acclimation to seawater polyculture of tilapia with shrimp bottom soil conditions nutrient requirements with non-nutrient components parasites and diseases Tilapia: Biology, Culture, and Nutrition is essential reading for aquaculturists, nutritionists, geneticists, hatchery managers, feed formulators, feed mill operators, extension specialists, tilapia growers, fish farmers/producers, educators, disease specialists, aquaculture veterinarians, policy makers, educators, and students.
