Book Synopsis The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish by : Jennifer D Jeffrey
Download or read book The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish written by Jennifer D Jeffrey and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In teleost fish, the main glucocorticoid stress hormone, cortisol, is released via the hypothalamic-pituitary-interrenal (HPI) axis. This thesis examined the premise that social status, maternal experience, and reproductive status affect HPI axis function in fish. Social stress in juvenile rainbow trout (Oncorhynchus mykiss) chronically elevates circulating cortisol levels. In this thesis, social subordinance as well as exogenous cortisol treatment resulted in decreased plasma adrenocorticotropic hormone (ACTH) levels, consistent with a negative feedback role of cortisol in modulating HPI axis activity. At the target tissue level, liver glucocorticoid receptor 2 (GR2) mRNA and total GR protein levels were lower in subordinate fish. Although subordinate fish exhibited elevated resting cortisol levels, cortisol and glucose responses to an acute stressor were attenuated. Using an in vitro head kidney preparation, this attenuated cortisol response was attributed to lower ACTH-stimulated production of cortisol. By contrast, dominant status regulated genes associated with cortisol biosynthesis. The consequences of maternal social status on offspring HPI axis function were investigated in zebrafish (Danio rerio). At 48 hours post-fertilization (hpf), when de novo cortisol synthesis becomes possible, larvae of dominant females exhibited lower baseline cortisol levels accompanied by lower mRNA levels of corticotropin-releasing factor and cytochrome P450 side chain cleavage enzyme. Offspring of subordinate females exhibited attenuated stress-induced levels of cortisol at 144 hpf, perhaps as an adaptive response to maternal stress experience. Finally, modulation of HPI axis function was explored as a mechanism underlying attenuation of the stress response during early paternal care in smallmouth bass (Micropterus dolomieu). In response to a stressor, males guarding free-swimming fry but not eggs elevated plasma ACTH and cortisol as well as mRNA levels of key HPI axis genes. These results point to a hypoactive HPI axis in males during early parental care as a mechanism for resistance to stress in these fish. Collectively, the results of this thesis emphasize the adaptive plasticity of the HPI axis. Activity of the HPI axis in teleost fish can be modulated by the individual's experience (e.g., social status) or circumstances (e.g., parental care), as well as by maternal stress.

Book Synopsis Reproductive Sciences in Animal Conservation by : Pierre Comizzoli
Download or read book Reproductive Sciences in Animal Conservation written by Pierre Comizzoli and published by Springer Nature. This book was released on 2019-08-30 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences. Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.
Book Synopsis The Welfare of Fish by : Tore S. Kristiansen
Download or read book The Welfare of Fish written by Tore S. Kristiansen and published by Springer Nature. This book was released on 2020-07-01 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues. Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.
Book Synopsis Sturgeon Fishes by : Tatiana A. Dettlaff
Download or read book Sturgeon Fishes written by Tatiana A. Dettlaff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive description of development of the Acipenserid fish published in the English language. It con tains the results of more than 40 years of studies by the authors and their colleagues. My own life in science has been intimately related both with the authors and the fish, which are the subject of this book. Therefore, it gives me a great pleasure to present to the English reader an expanded version of the book. Those interested in the history of biology must be well aware of the fact that genetics in the USSR was practically demolished by Lysenko at the session of the Lenin All-Union Academy of Agricultural Sciences in 1948. However, it is much less well known that other fundamental branches of biology were also persecuted at that time, experimental embryology (developmental mechanics) among them. As a result, many embryologists, in cluding the authors of this book, were forced to turn to more ap plied problems, this being the only way to continue research. They had to abandon amphibians and concentrate their efforts on sturgeon.

Download or read book Fish Welfare written by Edward J. Branson and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.
