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 more Survey of current research lacunae and the projected future of the discipline An authorial team of internationally renowned experts Epigenetics 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.

Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.

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.

Time to worry again—our lifestyle choices do impact our genetic code and that of our children (and even grandchildren!). "The potential is staggering. . . . The age of epigenetics has arrived."—Time, January 2010 Epigenetic means "on the gene," and the term refers to the recent discovery that stress in the environment can impact an individual's physiology so deeply that those biological scars are actually inherited by the next several generations. For instance, a recent study has shown that men who started smoking before puberty caused their sons to have significantly higher rates of obesity. And obesity is just the tip of the iceberg—many researchers believe that epigenetics holds the key to understanding cancer, Alzheimer's, schizophrenia, autism, and diabetes. Epigenetics is the first book for general readers on this fascinating and important topic. The book is driven by stories such as the Dutch famine of World War II, José Canseco and steroids, the breeding of mules and hinnies, Tazmanian devils and contagious cancer, and more.

The capacity of populations to adaptively evolve is generally thought to be constrained by the existing heritable genetic variation. Until recently, heritable genetic variation has been almost exclusively associated with variation in genomic DNA nucleotide sequences. There is increasing acceptance, however, that non-DNA nucleotide sequence-based variation - collectively termed ‘epigenetics’ - can affect ecologically important traits. While theoretical predictions of the role and significance of epigenetic inheritance in evolutionary adaptation are abundant, they remain largely untested, and few empirical studies are conducted in ecologically realistic contexts. As invasive species must rapidly adapt to new environments in which they have not evolved, it has been suggested that species invasions can be considered “experiments in evolution”. Using a highly invasive marine invertebrate, Didemnum vexillum (Phylum Chordata) as a model species, this thesis investigates the establishment and stability of epigenetic marks in different environments, while controlling for genotypic and environmental effects. I investigate the environmental induction of changes in one distinct source of epigenetic variation, DNA methylation. I provide a review of studies focused on DNA methylation and invasive species and identify knowledge gaps and potential ways to advance our understanding of epigenetic-based adaptation through the study of invasive species (Chapter 2). I explore DNA methylation patterns associated with invasiveness by comparing invasive and non-invasive D. vexillum clades (Chapter 3). I show that global DNA methylation patterns are significantly different between invasive populations and populations in the native range, which could be a common signature of invasive populations. I use laboratory experiments to explore two main questions: Do genome-wide DNA methylation patterns in D. vexillum change after exposure to environmental stress (non-optimal temperature and salinity) (Chapter 4), and are DNA methylation changes stable, or do they revert to their original state when colonies are returned to ambient (non-stressful) conditions (Chapter 5). Results indicate that environmental stress can induce significant global DNA methylation changes in D. vexillum on very rapid timescales, and that this response varies depending on the type, magnitude, and duration of the stressor. Environmentally induced DNA methylation can also be stable, which is a critical prerequisite for transgenerational epigenetic inheritance. My general discussion summarises the overall contribution of this research to the field of ecological epigenetics. This thesis represents a significant advancement in our understanding of the role of epigenetic mechanisms in marine invasions.
