Book Description
Small pelagic fish species found in lakes and introduced to reservoirs dominate by volume and contribute some of the most important inland fisheries in Africa with steadily increasing catches and additional potential. This circular reviews the status and importance of the pelagic fish and fisheries, together with small fish in general, for sustainable and healthy livelihoods in Africa. It reviews the biology and biological production of the most important pelagic species in lakes and reservoirs as well as the impacts of environmental and climatic variation on the stocks of these species. It examines and discuss the various capture techniques together with potential of improvements in the fisheries and associated processing and national and regional trade within Africa. The knowledge generated by the circular will be useful for policy makers and development practitioners to design and implement more effective policies, strategies and programs that will contribute to reducing the food insecurity and conflicts that currently affect the people in sub-Saharan Africa.

Book Description
One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.

Book Description
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.

Book Description
Authored by world-class scientists and scholars, The Handbook of Natural Resources, Second Edition, is an excellent reference for understanding the consequences of changing natural resources to the degradation of ecological integrity and the sustainability of life. Based on the content of the bestselling and CHOICE-awarded Encyclopedia of Natural Resources, this new edition demonstrates the major challenges that the society is facing for the sustainability of all well-being on the planet Earth. The experience, evidence, methods, and models used in studying natural resources are presented in six stand-alone volumes, arranged along the main systems of land, water, and air. It reviews state-of-the-art knowledge, highlights advances made in different areas, and provides guidance for the appropriate use of remote sensing and geospatial data with field-based measurements in the study of natural resources. Volume 5, Coastal and Marine Environments, discusses marine and coastal ecosystems, their biodiversity, conservation, and integrated marine management plans. It provides fundamental information on coastal and estuarine systems and includes discussions on coastal erosion and shoreline change, natural disasters, evaporation and energy balance, fisheries and marine resource management, and more. New in this edition are discussions on sea level rise, renewable energy, coral reef restoration, fishery resource economics, and coastal remote sensing. This volume demonstrates the key processes, methods, and models used through many case studies from around the world. Written in an easy-to-reference manner, The Handbook of Natural Resources, Second Edition, as individual volumes or as a complete set, is an essential reading for anyone looking for a deeper understanding of the science and management of natural resources. Public and private libraries, educational and research institutions, scientists, scholars, and resource managers will benefit enormously from this set. Individual volumes and chapters can also be used in a wide variety of both graduate and undergraduate courses in environmental science and natural science at different levels and disciplines, such as biology, geography, earth system science, and ecology.
