Download or read book Endocrine Sex Differentiation in Fish written by T. J. Pandian and published by CRC Press. This book was released on 2013-05-07 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all vertebrates, fish exhibit unparalleled diversity of sexual plasticity and flexibility, ranging from gonochorism to unisexualism, and exceptional patterns of functional hermaphroditism. Fish farming and monosex aquaculture have led to reproductive dysfunction with males producing less milt, and females failing to ovulate and spawn. This book brings together relevant information on the role of the endocrine system on sexual differentiation in fish, and bridges the gap between molecular endocrinologists and fishery scientists.

Download or read book Endocrine Disruption in Fish written by David E. Kime and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
Download or read book Nutritional and Environmental Modulation of the Endocrine System Effects on Metabolism and Growth written by Oliana Carnevali and published by Frontiers Media SA. This book was released on 2019-11-05 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present eBook is the result of the Frontiers Research Topic entitled “Nutritional and environmental modulation of the endocrine system: effects on metabolism and growth”. It contains 12 chapters, comprising 7 original research articles, 3 reviews, and 2 minireviews. The objective of the Research Topic was to provide a multidisciplinary approach of cutting-edge research on metabolism and growth aiming to address key questions about the interplay between nutritional, environmental or other external factors (i.e. temperature or pollutants) and signals modulating feed intake with the endocrine system, regulating these processes. Evidences about the molecular principle behind the complex interactions of all these factors on the control of the endocrine and nervous systems regulating the metabolic process are presented. The knowledge provided by this eBook focusing in cells, model organisms and farmed species, have highlighted the importance of dietary and environmental factors, and their interactions with the endocrine system to regulate growth and metabolism.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Download or read book Applied Animal Endocrinology 3rd Edition written by E. James Squires and published by CABI. This book was released on 2024-04-23 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the role of hormones in improving and monitoring the production, performance, reproduction, behaviour and health of livestock animals, focusing on cattle, pigs, sheep, horses, poultry and fish. Beginning with the principles of endocrinology and the methods to study endocrine systems, it then covers the different endocrine systems that affect different aspects of animal production and describes how these systems can be manipulated or monitored to advantage. The mechanism of action is covered, and common mechanisms and themes highlighted in order to understand potential methods for altering these systems, and stimulate ideas for the development of new methods. An invaluable text for students of animal science and veterinary medicine, this book also provides a useful resource for those in academia and industry interested in applications of endocrinology in animal production systems.

This book was released on 2013-08-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesizing decades of work, but up-to-date, this book focuses on organism-level responses to pollutants by marine animals, mainly crustaceans, molluscs, and fishes. Emphasizing effects on physiological processes (feeding/digestion, respiration, osmoregulation), life-cycle (reproduction [including endocrine disruption], embryo development, larval development, developmental processes later in life (growth, regeneration, molting, calcification, cancer), and behaviour, the book also covers bioaccumulation and detoxification of contaminants, and the development of tolerance. The major pollutants covered are metals, organic compounds (oil, pesticides, industrial chemicals), nutrients and hypoxia, contaminants of emerging concern, and ocean acidification. Some attention is also devoted to marine debris and noise pollution.
