This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising water temperatures are affecting the health and distribution of aquatic organisms. Brook trout (Salvelinus fontinalis), a popular freshwater sport fish adapted to cooler environments, is at risk to high temperature due to its habitat preferences. Using six acclimation temperatures that span the thermal distribution of the species (5C, 10C, 15C, 20C, 23C, and 25C), I quantified the stress response of juvenile brook trout by measuring physiological and molecular parameters to understand the processes that occur when fish are thermally stressed. Evidence of a stress response was apparent via exposure to a range of temperatures outside their preferred range (i.e., >20C) and by exhaustive exercise using a chase and air exposure protocol. Using qPCR, I quantified mRNA abundance of genes associated with stress and temperature-induced cellular mechanisms to aid in the identification of a sub-lethal temperature threshold for this species. Furthermore, I sought to understand the effect of acclimation temperature on their recovery when exposed to acute stress events that simulate the paired stressors of exhaustive exercise and air exposure; stressors that may be potentially associated with catch-and-release angling. I predicted that exposure to acclimation temperatures beyond those to be preferred by brook trout caused individuals to exhibit an increased stress response and increased recovery duration. My results indicate that brook trout are negatively affected by temperatures above 20C and a sub-lethal threshold exists between 20C and 23C. Brook trout exhibited signs of cellular impairment with upregulation of genes at 20C and above (Hsp90ab1, Hspa8, Gpx1) or downregulation at 20C and above (Nkcc and Nupr1). After exposure to paired stress events there was increased activation of the HPI axis at 20C and above as exhibited by elevated levels of cortisol, lactate, and glucose. Additionally, metabolic results suggested that energy expenditure is higher at elevated temperatures. These findings are imperative to understanding the implication of global climate change on brook trout populations and will be useful for managing fish habitat and regulating recreational angling.

Download or read book Physiological Adaptations to Swimming in Fish written by Josep V. Planas and published by Frontiers Media SA. This book was released on 2017-08-16 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors. Therefore, swimming is an important determinant factor of fitness in a true Darwinian sense and, not surprisingly, swimming performance has been often used as a measure of physiological fitness in fish. The main aim of this Research Topic is to showcase some of the current studies designed to improve our understanding of the physiological energetic and metabolic requirements of swimming and of the adaptive responses to swimming in fish.

Download or read book Centrarchid Fishes written by Steven Cooke and published by John Wiley & Sons. This book was released on 2009-09-08 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centrarchid fishes, also known as freshwater sunfishes, include such prominent species as the Largemouth Bass, Smallmouth Bass and Bluegill. They are endemic to Eastern North America where they form part of a multi-million dollar sports fishing industry, but they have also been widely introduced around the globe by recreational anglers, in aquaculture programs and by government fisheries agencies. Centrarchid Fishes provides comprehensive coverage of all major aspects of this ecologically and commercially important group of fishes. Coverage includes diversity, ecomorphology, phylogeny and genetics, hybridization, reproduction, early life history and recruitment, feeding and growth, ecology, migrations, bioenergetics, physiology, diseases, aquaculture, fisheries management and conservation. Chapters have been written by well-known and respected scientists and the whole has been drawn together by Professors Cooke and Philipp, themselves extremely well respected in the area of fisheries management and conservation. Centrarchid Fishes is an essential purchase for all fish biologists, ecologists, fisheries managers and fish farm personnel who work with centrarchid species across the globe.
Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Download or read book Migration of Freshwater Fishes written by Martyn Lucas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.
