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 scientistsComprehensive 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 fieldProvides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquacultureIncludes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed speciesSex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

EPIGENETICS IN AQUACULTURE This essential guide will allow you to understand how new developments in our knowledge of epigenetic mechanisms and epigenetic inheritance can be applied to improve aquaculture production and aquatic resource management and conservation. Epigenetics is the study of heritable changes in gene expression that are independent of alterations in the nucleotide sequence. It integrates genomic and environmental influences to shape the phenotype. Epigenetics is a field with particular relevance to aquaculture and aquatic organisms, since it underpins acclimatory responses to diverse and changing environments and inheritance of desired phenotypes. Epigenetics in Aquaculture provides a comprehensive introduction to epigenetics, epigenetic mechanisms, epigenetic inheritance, and research methods. It also provides the current state of the art on research and development on epigenetics in the major functions of aquatic organisms in the framework of aquaculture production. The fact that aquaculture is the fastest-growing sector of food production makes the book especially timely. Readers will also find: Detailed treatment of subjects including aquatic faunal reproduction, sex determination, growth regulation, nutritional programming, disease resistance, stress response and much moreSurvey of current research lacunae and the projected future of the disciplineAn authorial team of internationally renowned expertsEpigenetics in Aquaculture is a valuable reference for researchers, biologists and advanced students in any area of marine science, oceanography, aquaculture, environmental science, and food production.
