This book is dedicated to present different aspects of reproductive physiology and molecular endocrinology of commercially important as well as potential aquaculture fish species. The existing aquaculture generation is looking for species diversification for efficient utilization of available diverse water resources. The knowledge of reproductive physiology of fish will help in development of breeding strategy for use in commercial aquaculture. Reproductive system is highly coordinated and governed by means of complex network of nervous, endocrine system and environmental factor as well. This book emphasize on different key aspects of reproductive endocrine system such as basic gonadal biology in the events of climate vulnerability, sex determination, sex reversal, stimulatory hormones, inhibitory hormones and receptors, environmental and chemical factor guiding reproduction, puberty, neuroendocrine regulation of reproduction etc. This book further describes how reproduction is not just indispensable for the existence or survival of an individual, but it is important for the survival of species. Chapters also address the concerns of anthropogenic activities on fish and the aquatic environment lead main trouble on physiological and reproductive processes of aquatic animals. This book offers an attractive compilation of highly relevant aspects of current and future of aquaculture, especially in view of the growing awareness of aquaculture, to food scientists working on commercial fish, animal biologists, fish geneticists etc. This book is very timely, and relevant to the sustainable development goals. The contents would be relevant to policy makers, working towards blue revolution and blue economy.

This book summarizes the latest understanding of the impact of xenobiotics on the developmental and reproductive processes of aquatic animals, particularly nektonic forms, which comprise an important group of aquatic ecosystems. Aquaculture is quickly becoming the largest contributor of fish protein for human consumption. As the aquaculture business expands, farmed fish will be exposed to more environmental toxins, necessitating the use of chemical therapeutic drugs for fish. This book brings together experts on the regulation of environmental toxins and food chemicals from around the world, as well as researchers looking into the metabolism and disposal of foreign chemicals (xenobiotics) in fish species. The impact of xenobiotics on reproductive and developmental biology of all living forms has become of prime importance at the current time. As the effect of these xenobiotics on aquatic animals is an emerging area for research and development, several groups across the world are working on these aspects, targeting different groups of fishes in both marine and freshwater ecosystems. This collective work highlights several key and updated recent aspects of different types of xenobiotics entering aquatic ecosystems, impacts of these agents on reproductive physiology, developmental biology, breeding biology, hormonal imbalance, aquatic ecology, and pollution on the aquatic ecosystem. The unique aggregation of different types of stressors to aquatic animals under a single volume will be a useful reference for readers, including scientists, teachers, students, researchers and policymakers and those involved in aquaculture and environment conservation.

Anemonefishes, one of the most popular and recognizable of fishes in the world, are much more than film characters; they are also emerging model organisms for studying the biology, ecology, and evolution of coral reef fishes. They are a group of 28 species often employed to study patterns and processes of social organization, intra- and inter-specific competition, sex change, mutualism, dispersal and connectivity of fish populations, habitat selection, pigment pattern formation, lifespan and predator-prey interactions. This multi-authored book covers all these areas and provides an update on the research done with this model and the perspective it opens for the future. Key Features Contains basic and up-to-date information on an emerging fish model Allows non-specialist readers to grasp the relevance of a wide research area Provides accurate and easy to access information on each of the 28 species Includes guidance for establishing a breeding colony Documents that anemonefishes are useful model organisms for ecological, developmental and climate research

This book is a rich resource of important information on coldwater fish farming and coldwater fisheries management, including new research and recent technological advances. It aims to provide an understanding of the underlying mechanisms of coldwater physiology of fishes, which is essential for effective fishery management and for taking advantage of their vast potential application in aquaculture. Coldwater Fisheries and Aquaculture Management: Technology for Sustainable Food Production elaborates on key aspects associated with reproductive biology and endocrinology of coldwater fishes, such as gonadal development and maturation, vitellogenesis, steroidogenesis, whole genome information of fishes, transcriptomics, proteomics, and more. It also looks at genetic modification of coldwater fishes, phytobiotic-based feed to attain profitability in aquaculture, and the nutritional requirements of coldwater fishes, such as plant-based proteins in fish diets and feeding carbohydrates to fish. It also describes the beneficial dietary nutrition of fish consumption by humans. Several chapters address the various challenges to coldwater fish and fishery management, such as fish bacterial diseases (along with their immune components and defense mechanisms), unpredictable nature of climate change on fish, water pollution, etc. The volume also offers strategies on the sustainable management of fish that include looking at pollution in freshwater ecosystems, biotechnological interventions, predicting threats to fish from climate change, and other factors. This volume will be of value to those in fishery management and fish science as well as to marine researchers, faculty and students, and other involved with aquaculture science and management.

Hormones have a manifold impact upon growth and metabolism. This book focuses upon the molecular biology of fish hormones and their regulation. Chapters dealing with gonadotropin, corticotropin, vasotocin, isotocin, somatolactin, and other hormones are written by an international team of fish physiologists and endocrinologists. In addition, there are chapters that survey a growing literature on the ways hormones are regulated both in terms of their actions and in terms of the gene transcription that leads to their formation. The first two sections of the book covers brain and pituitary hormones and the latter two sections are devoted to other hormones and their regulation. As more and more endocrinologists and physiologists seek to use hormones that are inexpensive, provide for more facile experimental replication, and are less subject to cumbersome regulation, they will turn to the sorts of fish models reviewed in this book.

The successful reproduction of cultured brood stock is essential to the sustainable aquaculture of aquatic organisms. This book describes recent advances in the field of finfish reproductive biotechnology. The chapters in this volume are written by eminent scientists who review the progress and assess the status of biotechnology research that is applicable to the reproduction of finfish species for aquaculture. A wide range of topics is included starting with broodstock technologies such as broodstock genetics, broodstock nutrition, environmental control of maturation and impacts of stress on broodstock, gametes and progeny. The volume includes technologies for induction of ovulation and spermiation using synthetic hypothalamic peptides. Gamete technologies which are described include cryopreservation, chromosome set manipulation, disease prevention and control for gametes and embryos and the development of transgenic fish with enhanced production characteristics. Genetic and endocrine technologies for the production of monosex male and female fish stocks are also described.The closing chapter summarizes the discussion of each topic at the workshop, provides recommendations to industry and describes priorities of research and development. Researchers as well as teaching faculty in the aquaculture field will find this volume of great value.

With the decline in world fish stocks, our knowledge of fish reproduction has become fundamental. Reproduction is an essential commitment to future generation. It is also a continuous development process throughout ontogeny, requiring energetic, ecological, physiological, anatomical, biochemical and endrocrinological adaptations. The first chapters

One of the only books to discuss all vertebrates, the fourth edition of Vertebrate Endocrinology has been completely reorganized and updated to explore the intricate mechanisms that control human physiology and behavior as well as that of other vertebrate animals. Perfect for students in endocrinology, zoology, biology and physiology, it allows readers to gain both an understanding of the intricate relationships among all of the body systems and their regulation by hormones and other bioregulators, but also a sense of their development through evolutionary time as well as the roles of hormones at different stages of an animal's life cycle. Chapters have been reorganized to more closely follow traditional classroom presentation and extensive suggested readings are included at the end of each chapter allowing the reader to obtain further information as well as connect concepts to the literature on which the book is based. For the first time, this edition features four-color illustrations. - Provides a complete overview of the endocrine system of vertebrates by first emphasizing the mammalian system as the basis of most terminology and understanding of endocrine mechanisms and then applies that to non-mammals - Introduces the reader to suitable concepts and explanation of jargon so that the reader will be able to delve directly into the primary literature on any endocrine-related topic with a background that will aid in their interpretation of new information - Revised and updated chapter on The Molecular Bases for Chemical Regulation that now includes more evolutionary data - Includes information on endocrine disrupting chemicals and their implications on the health of wildlife and humans
