This book was released on 2008 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this thesis was to determine the metabolic and behavioural outcomes from hypoxia exposure to largemouth bass (Micropterus salmoides) yearlings when acclimated to either winter (5°C) or summer (20°C) temperatures. This was achieved by exposing largemouth bass to varying levels of hypoxia and subsequently quantifying metabolites, in addition to observing behavioural patterns. The critical partial pressure of oxygen was also determined for fish at both temperatures. Hypoxia experiments revealed that metabolite concentrations increased or decreased significantly compared to control values as hypoxia levels intensified at 20°C, however there were minimal changes for fish at 5°C. More specifically, end product concentrations of lactate increased, while substrate concentrations of ATP, PCr and glycogen decreased and glucose concentrations did not change significantly at 20°C. It was also found that the magnitude of change was greater for fish at 20°C, indicating the impact of hypoxia is greater at warmer temperatures. In addition, it was noted that hypoxia experiments performed at either identical percent oxygen saturation (%) or identical dissolved oxygen (mg/L) resulted in very similar metabolite trends at both temperatures. In terms of behaviour, ventilation rates increased significantly and peaked at 2mg/L for largemouth bass at 20°C, however there was no change for fish at 5°C. There were also more instances of aquatic surface respiration with increasing hypoxia for fish at 20°C, but nearly no attempts at 5°C. Critical partial pressure of oxygen (Pcrit) values were calculated to be 1.36 " 0.02 mg/L (16% oxygen saturation) for 20°C and 0.77 " 0.04 mg/L (5% oxygen saturation) for 5°C fish respectively. The Pcrit levels corresponded to the hypoxia levels that initiated changes in metabolite concentrations at each temperature, thus indicating that largemouth bass undergo anaerobic metabolism. This study shows that the overall impact of hypoxia on largemouth bass yearlings was much greater in warmer water. These results indicate that hypoxia may become a very important physiological stress on younger life stages of fish as water temperatures increase with climate change.

This book was released on 2018 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angling practices subject Largemouth Bass Micropterus salmoides to multiple stressors, causing homeostatic physiological disturbances. The combined effects of ambient and live well temperature on stress responses from exercise have not been thoroughly examined. Large numbers of fish required for stress experiments can be produced by intensive culture, but hatchery fish may differ physiologically from wild fish due to dietary carbohydrates. Therefore, the effects of diet, population, and temperature on stress response and health were examined. Stress responses were similar among fish fed formulated and live diets and liver health improved within 4-6 weeks. Although cortisol responses of hatchery and wild fish differed, secondary stress responses were similar. Fish subjected to simulated angling at temperatures of 17, 25, 33 °C with live well temperature differentials of -4, 0, +4 °C, had the lowest resilience to stress at the warmest temperatures, exhausting energy supplies, coincident with metabolic acidosis and poor ion regulation.
Book Synopsis Fish Physiology: Hypoxia by : Jeffrey G. Richards
Download or read book Fish Physiology: Hypoxia written by Jeffrey G. Richards and published by Academic Press. This book was released on 2009-03-10 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry. The only single volume available to provide an in-depth discussion of the adaptations and responses of fish to environmental hypoxia Reviews and synthesizes the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure Includes discussion of the evolutionary and ecological consequences of hypoxia exposure in fish

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.
Book Synopsis Water Pollution and Fish Physiology by : Alan G. Heath
Download or read book Water Pollution and Fish Physiology written by Alan G. Heath and published by CRC Press. This book was released on 2018-02-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise synthesis of how toxic chemical pollutants affect physiological processes in teleost fish. This Second Edition of the well-received Water Pollution and Fish Physiology has been completely updated, and chapters have been added on immunology and acid toxicity. The emphasis, as in the first edition, is on understanding mechanisms of sublethal effects on fish and their responses to these environmental stressors. The first chapter covers the basic principles involved in understanding how fish respond, in general, to environmental alterations. Each subsequent chapter is devoted to a particular organ system or physiological function and begins with a short overview of normal physiology of that system/function. This is followed by a review of how various toxic chemicals may alter normal conditions in fish. Chapters covering environmental hypoxia, behavior, cellular enzymes, and acid toxicity are also included. The book closes with a discussion on the practical application of physiological and biochemical measurements of fish in water pollution control in research and regulatory settings.
