Available in PDF, EPUB and Kindle. Book excerpt: Conservation Physiology for the Anthropocene: A Systems Approach, Volume 39A in the Fish Physiology series, is a comprehensive synthesis on the physiology of fish in the Anthropocene. This volume closes the knowledge gap by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to management and conservation. As the world is changing, with a dire need to identify solutions to the many environmental problems facing wild fish populations, this book comprehensively covers conservation physiology and its future techniques. Conservation physiology reveals the many ways in which environmental change and human activities can negatively influence wild fish populations. These tactics inform new management and conservation activities and help create the necessary conditions for fish to thrive. - Presents authoritative contributions from an international board of authors, each with extensive expertise in the conservation physiology of fish - Provides the most up-to-date information on the ways in which different physiological systems are relevant to the management and conservation of fish and fisheries - Identifies how anthropogenic stressors perturb physiological systems - Explores how different physiological systems can be exploited to solve conservation problems

This book was released on 2018 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the role that environment and geographic landscape features have on migratory response in juvenile brown trout (Salmo trutta). Migratory strategy was found to be related to landscape features at the catchment scale. Migratory populations occurred at lower elevations where migratory journeys were less costly. Furthermore, migratory populations were characterised by high juvenile density and suppressed growth rates, indicating competition for resources. Invertebrate biomass interacted with landscape features, presumably by alleviating competition where invertebrate biomass was high, and played a role in out-migration. A temporal study on a migratory population of brown trout showed that space resources became constrained over a season. In situ filming of fish showed that the number of foraging stations first increased and then decreased, as stream flow and discharge decreased over the season. This was presumably due to a reduction in the number of profitable foraging stations available and offers a mechanistic explanation for the decline in fish numbers - losers in competitive interactions for foraging stations are forced to migrate. The effects of intra-cohort competition could be observed in declining individual condition factors and loss of fish (out-migration) from the stream. The role of food as a proximal cue regulating out-migration has received increasing attention as salmonid restocking programs try to increase the return rate of released fish. Producing a fish similar to wild types, including migratory tendencies, is difficult. A simple method might be to reduce the amount of food rations given to fish, creating leaner individuals more inclined to migrate on release. In this thesis, I find that food rations could affect the degree of smolting (physiological change prior to migration) under standard hatchery conditions. Fish fed low rations in spring prior to out-migration showed a greater degree of smoltification. A meta-analysis on the effect of food on migration in salmonids found that rationing food had different effects on different species of salmonid. Rationing had a direct effect on migratory response in more irruptive migratory species (trout), but not so in more regular migratory species (salmon). The terms irruptive and regular migration have their roots in avian ecology, but I propose they are equally applicable to salmonids. The findings of this thesis are used to form a hypothesis for the environmental regulation of patterns of residency and migration in brown trout.

Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Tropical Fishes is the 21st volume of the well-known Fish Physiology series and consists of 12 chapters. The purpose of the book is to consolidate and integrate what is known about tropical fishes (marine and freshwater species). The twelve chapters focus on the physiological adaptations acquired during the evolutionary process to cope with warm and shallow hypoxic waters from tropical and neotropical hydrographic basins as well as with the intertidal and coral reef habitats which occur in abundance in tropical seas. The special characteristics of tropical fish fauna will be issued in order to explain the tropical fish radiation, which gave rise to such extreme fish diversity. This present volume, is a voyage through the tropical region reviewing the fish diversity of the main tropical freshwater sheds, including the major tropical rivers and lakes, the major dams, and marine environments. State-of-the-art information on tropical fish physiology Written by specialists working in the Tropics Offers a diverse depiction of the various tropical fishes and the environment where they inhabit 12 innovative chapters covering a concise view of growth rate, biological rhythms, feeding plasticity, cardio-respiratory design and function, diversity of structure, and much more
