Download or read book Limnology Climatology and Paleoclimatology of the East African Lakes written by A.Ivan Johnson and published by Routledge. This book was released on 2019-08-13 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Available in PDF, EPUB and Kindle. Book excerpt: The report synthesizes the findings of ten case studies published in FAO Fisheries Technical Paper 426/2. The case studies have been conducted in five medium-sized lakes in the Democratic Republic of the Congo, Malawi, Zambia and Zimbabwe. The synthesis focuses on three features relevant for the SADC region: How has fishing effort developed in these lakes over the last 50 years? What causes changes in fishing effort? How do fishing effort and environmental factors compare in their effects on the regeneration of fish stocks?

Download or read book Aquaculture Technology in Developing Countries written by Randall E. Brummett and published by Routledge. This book was released on 2016-04-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture technology has been evolving rapidly over the last two decades, led by an increasingly skilled cadre of researchers in developing countries. Rather than copying, or adapting work done in industrialized countries to their situations, these scientists are moving aquaculture research out of the box to explore species and production systems relevant to their natural resources, economies and social institutions. Studies from India, Latin America, the Middle East and Africa are highlighted in this collection of papers, covering the entire gamut of aquaculture science from comparison of tilapia breeds, novel feed ingredients for indigenous species, improving disease resistance, water-use efficiency, traditional farming systems, spatial planning and economics. More than a how-to book, this volume introduces the researchers and institutions leading the development of aquaculture as it expands into new frontiers. This book was based on a special issue of the Journal of Applied Aquaculture.
