Ecology and Conservation of Fishes


Book Description

Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.




Fish Ecology and Adaptation


Book Description

1) INTRODUCTION OF ECOLOGY - The study of biology contemplates collaborations between singular life forms and their surroundings, incorporating communications with the two conspecifics and individuals from different species. In spite of the fact that nature arose in the nineteenth century a lot of its hypothetical structure just arose in the 20th century. Despite the fact that nature incorporates a wide assortment of sub-fields, philosophical investigation of environment has so far been confined to populace, network, and biological system biology. Focal philosophical issues incorporate explanation of significant ideas of natural variety and solidness the connection among variety and dependability. Other discussed questions are the idea of laws and speculations in nature, methodologies of model-building, and reductionism. Contemporary nature is going through a calculated change in view of expanded computational force. The new accentuation on individual-based models, which grasp methodological independence, ought to be seen as an arrival of reductionism in nature. Other significant advancements remember far reaching interest for spatially express models and the approach of Geographical Information Systems.




Diversity and Adaptation in Fish Behaviour


Book Description

Fish are extremely successful vertebrates. Because of a long and divergent history they are now found in almost every conceiv able aquatic habitat. This radiation has been accompanied by great diversity in structure, physiology, and behaviour. Despite this variability, fish must solve a number of basic problems that are common to all animals. The most important of these are: (1) to find and ingest appropriate food; (2) to avoid predation; and (3) to reproduce. The main purpose of this book is to describe the variety of behavioural strategies that fish use in coping with these problems. My approach has been to draw together material from both field and laboratory work that is widely scattered in the litera ture. The major emphasis is on field studies, since my main concern is with adaptive solutions to problems, and I believe these are most likely to be correctly perceived by workers who are familiar with the natural ecological setting of their animals. Of course, many details of behaviour cannot be seen and quantified adequately in the field, and therefore I have not ignored laboratory studies. However, even here I have concen trated on work that illustrates the variety of solutions that fish use to solve the three basic problems. Much important work, for instance on causation, development, and learning, is not included.




Extremophile Fishes


Book Description

This book summarizes the key adaptations enabling extremophile fishes to survive under harsh environmental conditions. It reviews the most recent research on acidic, Antarctic, cave, desert, hypersaline, hypoxic, temporary, and fast-flowing habitats, as well as naturally and anthropogenically toxic waters, while pointing out generalities that are evident across different study systems. Knowledge of the different adaptations that allow fish to cope with stressful environmental conditions furthers our understanding of basic physiological, ecological, and evolutionary principles. In several cases, evidence is provided for how the adaptation to extreme environments promotes the emergence of new species. Furthermore, a link is made to conservation biology, and how human activities have exacerbated existing extreme environments and created new ones. The book concludes with a discussion of major open questions in our understanding of the ecology and evolution of life in extreme environments.




Environmental Physiology of Fishes


Book Description

A very good piece of work, I assure you, and a merry. -Now, good Peter Quince, call forth your actors by the scroll. -Masters, spread yourselves. A Midsummer Night's Dream. Act 1, Sc. 2 This volume is the outcome of a NATO Advanced Study Institute held in August 1979 at Bishop's University, Lennoxville, Quebec, Canada. About 130 participants from all the countries of the aJiiance as well as India and Japan attended this event which lasted two weeks. Seventeen of these participants had been invited to present reviews of chosen topics, usually in their specialty. This book is constituted mainly of these presentations, which were prepared as chapters. In addition, six of the participants, whose seminars were found to complement the main chapters, were coopted by the invited lectures/authors to provide additional chapters. Although a lecture was given on electric fields, a chapter on this matter is unfortunately absent due to the lack of preparation time. One may say that Environmental Physiology of Fishes as a discipline originated in Canada. Having been involved as a teacher and worker in this field since 19 54, it was but natural that I was tempted to organise an ASI and get a volume out on the matter. I was encouraged by discussions with colleagues and the acceptance on the part of a large number of eminent colleagues to attend the ASI, deliver lectures and write chapters.




Ecology of Teleost Fishes


Book Description

Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious and delicious food of numerous kinds. Rational expoitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.




The Senses of Fish


Book Description

Fish comprise more than 50% of all living vertebrates and are found in a wide range of highly diverse habitats like the deep sea, the shoreline, tide pools, tropical streams and sweetwater ponds. During evolution, the senses of fish have adapted to the physical conditions of the environment in which different species live. As a result, the senses of fish exhibit a remarkable diversity that allows different species to deal with the physical constraints imposed by their habitat. In addition, fish have evolved several `new' sensory systems that are unique to the aquatic environment. In this book, examples of adaptation and refinement are given for six sensory systems: The visual system, The auditory system, The olfactory system, The mechanosensory lateral line system, The taste system, The electrosensory system. In each case, the environmental conditions under which a particular group of fish lives are analyzed. This is followed by a description of morphology and physiology of the sensory system and by an evaluation of its perceptional capabilities. Finally, the sensory adaptations to the particular conditions that prevail in the habitat of a species are highlighted. The various examples from different groups of fish presented in this book demonstrate the impressive capability of fish sensory systems to effectively overcome physical problems imposed by the environment.

The Ecology of Fishes on Coral Reefs


Book Description

This book provides a comprehensive and up-to-date review of the ecology of coral reef fishes presented by top researchers from North America and Australia. Immense strides have been made over the past twenty years in our understanding of ecological systems in general and of reef fish ecology in particular. Many of the methodologies that reef fish ecologists use in their studies will be useful to a wider audience of ecologists for the design of their ecological studies. Significant among the impacts of the research on reef fish ecology are the development of nonequilibrium models of community organization, more emphasis on the role of recruitment variability in structuring local assemblages, the development and testing of evolutionary models of social organization and reproductive biology, and new insights into predator-prey and plant-herbivore interactions.




Migration Ecology of Marine Fishes


Book Description

A synthetic treatment of all marine fish taxa (teleosts and elasmobranchs), this book employs explanatory frameworks from avian and systems ecology while arguing that migrations are emergent phenomena, structured through schooling, phenotypic plasticity, and other collective agencies. The book provides overviews of the following concepts: The comparative movement ecology of fishes and birds; The alignment of mating systems with larval dispersal; Schooling and migration as adaptations to marine food webs; Natal homing; Connectivity in populations and metapopulations; The contribution of migration ecology to population resilience
