Available in PDF, EPUB and Kindle. Book excerpt: De l’origine des espèces et des premiers inventaires naturalistes aux pratiques de pêche traditionnelles et actuelles, en passant par la systématique et l’écologie des principales familles, ce livre dresse un panorama complet et richement illustré des poissons d’eau douce africains. Les représentations symboliques et artistiques ancestrales, ainsi que de nombreux témoignages actuels, invitent le lecteur à découvrir comment la pêche et les poissons continuent d’imprégner profondément les sociétés africaines. La domestication des espèces, à travers la pisciculture et l’aquariophilie, est également abordée. Ce livre n’a pas le format classique des ouvrages scientifiques. En effet, les auteurs ont fait le choix de diversifier les sources d’information et de privilégier l’iconographie, afin de rendre la lecture plus attrayante pour un lecteur non spécialiste. Ainsi, la parole est donnée à des chercheurs de différentes disciplines et à des pêcheurs, qui témoignent de leurs connaissances théoriques et empiriques des poissons et de la pêche.

Download or read book The Contested Floodplain written by Tobias Haller and published by Rowman & Littlefield. This book was released on 2013 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Contested Floodplain tells the story of institutional changes in the management of common pool resources (pasture, wildlife, and fisheries) among Ila and Balundwe agro-pastoralists and Batwa fishermen in the Kafue Flats, in southern Zambia. It explains how and why a once rich floodplain area, managed under local common property regimes, becomes a poor man's place and a degraded resource area. Based on social anthropological field research, the book explains how well working institutions in the past, regulating communal access to resources, have turned into state property and open access or privatization. As a basis for analysis, the author uses Elinor Ostrom's design principles for well working institutions and the approach of the New Institutionalism by Jean Ensminger. The latter approach focuses on external factors and change in relative prices. It explains how local actors face changing bargaining power and use different ideologies to legitimize and shape resource use regulations. The study focuses on the historic developments taking place since pre-colonial and colonial times up to today. Haller shows how the commons had been well regulated by local institutions in the past, often embedded in religious belief systems. He then explains the transformation from common property to state property since colonial times. When the state is unable to provide well functioning institutions due to a lack in financial income, it contributes to de facto open access and degradation of the commons. The Zambian copper-based economy has faced crisis since 1975, and many Zambians have to look for economic alternatives and find ways to profit from the lack of state control (a paradox of the present-absent state). And while the state is absent, external actors use the ideology of citizenship to justify free use of resources during conflicts with local people. Also within Zambian communities, floodplain resources are highly contested, which is illustrated through conflicts over a proposed irrigation scheme in the area. The different actors and interest groups use ideologies such as citizenship vs. being indigenous, ethnic identity vs. class conflict, and modernity vs traditional way of life to legitimize land claims.
Download or read book Faune des poissons d eaux douces et saum tres de l Afrique de l Ouest written by Didier Paugy and published by IRD Orstom. This book was released on 2003 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new reexamined and corrected fauna displays an up to date account of knowledge on the systematics of the fresh and brackish water fishes of West Africa. Its aim is to help ichthyologists with the identification of the species they collect. It is made practical and didactic by paying special attention to iconography and as far as possibly by giving priority to the simplest and easiest observable criteria. West Africa, from the Senegal River basin in the North West to the Chad basin in the North East and the Cross River in the South, includes the majority of the Sahelo-Sudan basins, except for the Nile, and the Western Guinea area, covering the Atlantic Coastal Basins from Guinea to Western Cote d'Ivoire. Specialists of each group or family were called to write the chapters. To facilitate the access of this fauna, an English translation is provided for all text. Summary tables, comparing morphological characters and measures for the different species, complement the identification keys. Distribution maps are provided for freshwater species. At present, 64 families are described, including 192 genera and 584 valid species. A reduced paper version is presented in two volumes; the integral CD-ROM version is inserted on the back cover of the second volume.

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.
Download or read book The Diversity of Fishes written by Douglas E. Facey and published by John Wiley & Sons. This book was released on 2022-12-05 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE DIVERSITY OF FISHES The third edition of The Diversity of Fishes is a major revision of the widely adopted ichthyology textbook, incorporating the latest advances in the biology of fishes and covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. Key information on the evolution of various fishes is also presented, providing expansive and conclusive coverage on all key topics pertaining to the field. To aid in reader comprehension, each chapter begins with a summary that provides a broad overview of the content of that chapter, which may be particularly useful for those using the text for a course who don’t intend to address every chapter in detail. Detailed color photographs throughout the book demonstrate just some of the diversity and beauty of fishes that attract many to the field. A companion website provides related videos selected by the authors, instructor resources, and additional references and websites for further reading. Sample topics covered and learning resources included in The Diversity of Fishes are as follows: How molecular genetics has transformed many aspects of ichthyology The close relationship between structure and function, including adaptations to special environments Many physical and behavioral adaptations reflecting the fact that many fishes are both predators and prey Fish interactions with other species within fish assemblages and broader communities, plus their impacts on ecosystems Global maps that more accurately represent the comparative sizes of oceans and land masses than maps used in prior editions For students, instructors, and individuals with an interest in ichthyology, The Diversity of Fishes is an all-in-one introductory resource to the field, presenting vast opportunities for learning, many additional resources to aid in information retention, and helpful recommendations on where to go to explore specific topics further.

Available in PDF, EPUB and Kindle. Book excerpt: During the past two decades, fish endocrinology has witnessed exciting developments due to our increased knowledge at all levels of biological organizations, including molecular biology, cell biology, physiology and behavior. New insights into development, neurobiology, immunology and molecular genetics closely correlated with classical aspects of endocrinology and represent important contributions to our knowledge on regulatory processes of vertebrates, including fish. The purpose of this book is to overview major advances in numerous research areas of fish endocrinology. Most of the chapters not only review and discuss the state-of-the-art in the respective field, but also show perspectives of future research. The book will be of interest to scientists involved in basic fish research, comparative endocrinology, fisheries and aquaculture as well as for students of fish biology.
