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 Electrophoretic and Isoelectric Focusing Techniques in Fisheries Management written by Donald H. Whitmore and published by CRC Press. This book was released on 1990-09-24 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Probably the most ubiquitous biochemical method used today for examining the genetics of individuals, populations, or phylogenetic relationships between taxa is electrophoresis. This book has been created to offer a viewpoint regarding current electrophoretic separation methodologies of macromolecules and their major applications to fisheries management. The chapters in this book have been selected and organized into three sections to create a carefully blended mixture of methodologies and applications designed to educate the novice, as well as stimulate interest in professional researchers currently using electrophoresis for their work. The first section includes chapters that discuss the principles that explain the genetic basis of multiple molecular forms of proteins, the theory and practice of DNA analyses, and the methodology of electrophoretic separation of these macromolecules; starch gel electrophoresis as the predominant electrophoretic tool for fisheries genetics; and protein isoelectric focusing and DNA analysis. The second section describes a variety of applications for electrophoretic techniques. The third section presents a discussion and results of experiments conducted by Dennis Powers and his associates regarding the physiological significance of multiple forms of enzymes using the fish Fundulus heteroclitus as a model system. The book features a catalog of nearly 100 enzyme staining recipes and covers new areas in electrophoretic work, such as DNA fingerprinting, genetic tags, mitochondrial DNA methodologies, and genomic manipulation of fish stocks. This book will provide a useful reference resource for fisheries biologists at federal, state, and local levels; fisheries researchers at universities; and students pursuing degrees involving research in fish genetics.

Download or read book Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 1810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Available in PDF, EPUB and Kindle. Book excerpt: Bivalve Molluscs is an extremely comprehensive book coveringall major aspects of this important class of invertebrates. As wellas being an important class biologically and ecologically, many ofthe bivalves are fished and cultured commercially (e.g. mussels,oysters, scallops and clams) in a multi-billion dollar worldwideindustry. Elizabeth Gosling who has a huge wealth of research, teachingand hands on experience working with bivalves, has written alandmark book that will stand for many years as the standard workon the subject. Chapters in Bivalve Molluscs covermorphology, ecology, feeding, reproduction, settlement andrecruitment, growth, physiology, fisheries, aquaculture, genetics,diseases and parasites, and public health issues. A fullunderstanding of many of these aspects is vital for all thoseworking in bivalve fisheries and culture. An essential purchase for anyone concerned with this importantclass of animals, copies of Bivalve Molluscs should be onthe shelves of biologists, ecologists, environmental scientists,fisheries scientists and personnel within the aquaculture industry.Copies of the book should be available in all libraries andresearch establishments where these subjects are studied ortaught. Elizabeth Gosling is based at the Galway-Mayo Instituteof Technology, Galway, Ireland.

Download or read book Selection and Breeding Programs in Aquaculture written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2005-04-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
