Download or read book Trout and Salmon written by Trevor Crisp and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important book contains a great wealth of practical information on trout and salmon, species of fish that are of huge scientific and commercial interest. The introductory chapters of Trout and Salmon cover the biology and environmental variables of importance when considering these species. Further chapters encompass current information on the ecology of salmon and trout, with particular emphasis on the definition and quantification, where possible, of their environmental requirements and limitations. Comprehensive coverage of the impacts of human activities on trout and salmon is included, together with important aspects of relevance when considering issues of species conservation and habitat restoration. The book concentrates on the two species of the genus Salmo with many references and comparisons with the genus Oncorhynchus. Conclusions drawn within the book apply to both genera and as such the book will have relevance for both Europe and North America as well as other areas where these genera occur. Trevor Crisp has written a book that will be of great interest and use to fish biologists and fisheries scientists, to aquatic biologists, conservationists, ecologists and environmental scientists. The book will be particularly valuable for those working in government environment agencies and fish and wildlife departments and to all those involved in the management of these important species, their fisheries and habitats.

Download or read book Tilapias Biology and Exploitation written by M.C.M Beveridge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

Book excerpt: Volume 26 of this important series will be of particular interest to fish biologists. Haug's review of Atlantic halibut presents a complete summary of this important species both as a subject of a pelagic fishery and a developing aquaculture industry. Kjorsvik and his colleagues focus on the importance of egg quality for the mass production of fish fry. They point to a number of characters that may be indicative of egg quality and which may help to assess their likelihood of producing good fry.****Neilson and Perry review the studies of diel movements in fish and conclude that they are often facultative in nature. The implications for fish sampling are discussed.****Finally, Burd and Nemec examine the development of practical approaches towards the methods of analyzing benthic infauna, pointing out the assumptions and limitations of each.

Download or read book Ecology of Australian Freshwater Fishes written by Paul Humphries and published by CSIRO PUBLISHING. This book was released on 2013-04-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume reviews our past and present understanding of the ecology of Australian freshwater fishes. It compares patterns and processes in Australia with those on other continents, discusses the local relevance of ecological models from the northern hemisphere and considers how best to manage our species and their habitats in the face of current and future threats. In view of these challenges, the need for redress is urgent. The chapters are written by some of our foremost researchers and managers, developing themes that underpin our knowledge of the ecology, conservation and management of fish and fish habitats. For each theme, the authors formulate a synthesis of what is known, consider the need for new perspectives and identify gaps and opportunities for research, monitoring and management. The themes have an Australian context but draw upon ideas and principles developed by fish biologists in other parts of the world. The science of freshwater fish ecology in Australia has grown rapidly from its roots in natural history and taxonomy. This book offers an introduction for students, researchers and managers, one that the authors hope will carry Australian fish biology and resource management to new levels of understanding.

Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

Download or read book Ecology of Teleost Fishes written by Robert J. Wootton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
