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 Poissons d Afrique et peuples de l eau written by Didier Paugy and published by IRD Éditions. This book was released on 2015-03-25 with total page 323 pages. 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.

This book was released on 2018-05-08 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean covers 70 percent of the Earth’s surface, and is essential for life on our planet – even for those of us who live nowhere near the sea! It provides us all with food and other materials that we need, regulates our climate and provides half of the oxygen we breathe. The ocean also offers us various means of transport and opportunities for recreation. People have long thought that the ocean was so wide and bountiful that it would go on supplying our needs forever, but this is not the case: human activities are causing significant damage to life in the ocean. People are often unaware of the problems created by this heavy reliance, as few of us have the opportunity to look beneath the surface of the sea and see the damage that our actions have caused. This is where the Ocean Challenge Badge comes in: let it take you on a journey to discover the ocean! It is packed with activities to help you learn about how the ocean works, the creatures that live in it, and just how important it is in our everyday lives. You will also discover how YOU can play a role in protecting our ocean for future generations. We hope you will be inspired to take the challenge and celebrate our ocean. So dive in and begin your aquatic discoveries!

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.
