Download or read book Freshwater small pelagic fish and their fisheries in the major African lakes and reservoirs in relation to food security and nutrition written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-02-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Lake Naivasha, Kenya by : David M. Harper
Download or read book Lake Naivasha, Kenya written by David M. Harper and published by Springer Science & Business Media. This book was released on 2003-05-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive study of an east African lake for thirty years. It represents the culmination of research expeditions which stretch back twenty years and is thus able to pick up long term changes which the individual research activities do not reveal. Lake Naivasha is a tropical lake whose natural fluctuations are now dwarfed by human impacts. Papers show how the irrigation for horticulture and power cooling has reduced the lake depth significantly; exotic arrivals have altered the plant community beyond recognition and its commercial value as a fishery and a tourist feature are reduced by over use. Despite this, the lake has considerable conservation value at present. It provides a different case study in the ever-growing library of the effects of human follies. Lake Naivasha has achieved global importance in the past ten years because its waters are used to sustain the largest horticultural industry in Africa. The book highlights its fragility under such pressure and points out the way towards sustainable use of the water and the ecosystem.

Book Synopsis A review of major river basins and large lakes relevant to inland fisheries by : Ainsworth, R., Cowx, I.G., Funge-Smith, S.J.
Download or read book A review of major river basins and large lakes relevant to inland fisheries written by Ainsworth, R., Cowx, I.G., Funge-Smith, S.J. and published by Food & Agriculture Org.. This book was released on 2021-01-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review presents summary information on 45 river and great lake basins of the world, which support inland fisheries. The information presented is drawn from published information in peer-reviewed journals as well as grey literature. Each basin summary is presented in a common format, covering the description of the fishery, estimates of catch and numbers of people engaged in the fishery, important biodiversity features and threats to the fishery. An analysis of the replacement costs of inland fish of the basin is also presented. This is expressed in terms of the water, land and greenhouse gas footprint that would arise if the inland fish that are currently produced had to be replaced with other forms of food (such as aquaculture fish, livestock or field crops).

Book Synopsis Tilapias: Biology and Exploitation by : M.C.M Beveridge
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.
Download or read book Africa's Lakes written by and published by UNEP/Earthprint. This book was released on 2006 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared as part of UNEP's contribution to the 11th World Lakes Conference (held in Nairobi, Kenya in November 2005), this publication examines the environmental changes taking place to Africa's lakes by analysing ground photographs, current and historical satellite images and scientific evidence. Changes highlighted include the rapid shrinking of Lake Songor in Ghana, partly as a result of intensive salt production, and the extraordinary changes in the Zambezi river system as a result of the building of the Cabora Basa dam site. Other impacts, some natural and some human-made and which can only be truly appreciated from space, include the extensive deforestation around Lake Nakuru in Kenya, and the falling water levels of Lake Victoria which is now about a metre lower than it was in the early 1990s. The analysis recognises the importance of Africa's lakes as a source of livelihoods for many local communities, their contribution to the socio-economic development of the continent and the need for the sustainable management of these resources in order to help overcome poverty and meet internationally agreed development goals by 2015.
Book Synopsis Lake Victoria Fisheries Resources by : Yunus D. Mgaya
Download or read book Lake Victoria Fisheries Resources written by Yunus D. Mgaya and published by Springer. This book was released on 2017-11-28 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book synthesises the historical trends of the lake fisheries, the lake ecology, biology and biodiversity, socio-economics, stock assessment, aquaculture, fish quality assurance, environmental quality and management of the fisheries resources. The evolution of fisheries in Lake Victoria has undergone dramatic changes over the last few decades, leading to both ecological and socio-economic consequences. The lake has changed from one dominated by haplochromines in the 1950s, to one currently dominated by Nile perch, ‘dagaa’ (Rastrineobola argentea) and Nile tilapia. These changes have mainly been driven by the introduction of the predatory Nile perch in the lake, eutrophication due to increased human activities in the catchment, increased human population growth, overfishing and changes in the global climate system. This work should therefore be a particularly useful reference to fisheries scientists and managers, potential investors, students and other professionals who may be interested in the Lake Victoria fisheries.
Book Synopsis The East African Great Lakes: Limnology, Palaeolimnology and Biodiversity by : Eric O. Odada
Download or read book The East African Great Lakes: Limnology, Palaeolimnology and Biodiversity written by Eric O. Odada and published by Springer Science & Business Media. This book was released on 2006-03-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.
Book Synopsis The Behavior, Ecology and Evolution of Cichlid Fishes by : Maria E. Abate
Download or read book The Behavior, Ecology and Evolution of Cichlid Fishes written by Maria E. Abate and published by Springer Nature. This book was released on 2021-09-19 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the most recent and most comprehensive consideration of the largest family of bony fishes, the Cichlidae. This book offers an integrated perspective of cichlid fishes ranging from conservation of threatened species to management of cichlids as invasive species themselves. Long-standing models of taxonomy and systematics are subjected to the most recent applications and interpretations of molecular evidence and multivariate analyses; and cichlid adaptive radiations at different scales are elucidated. The incredible diversity of endemic cichlid species in African lakes is revisited as possible examples of sympatric speciation and as serious cases for management in complex anthropogenic environments. Extreme hydrology and bathymetry as driver of micro-allopatric speciation is explored in the African riverine hotspot of diversity of the lower Congo River. Dramatic new molecular evidence draws attention to the complex taxonomy and systematics of Neotropical cichlids including the crater lakes of Central America. Molecular genetics, genomics, imaging tools and field study techniques assess the roles of natural, sexual and kin selection in shaping cichlid traits and beyond. The complex behavioral adaptations of cichlids are considered from a number of sub-disciplines including sensory biology, neurobiology, development, and evolutionary ecology. Most importantly, this volume puts forth a wealth of new interpretations, explanatory hypotheses and proposals for practical management and applications that will shape the future for these remarkable fishes in nature as well as their use as models for the study of biology.
Book Synopsis Schistosomiasis by : Mohammad Bagher Rokni
Download or read book Schistosomiasis written by Mohammad Bagher Rokni and published by BoD – Books on Demand. This book was released on 2012-01-13 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the wake of the invitation by InTech, this book was written by a number of prominent researchers in the field. It is set to present a compendium of all necessary and up-to-date data to all who are interested. Schistosomiasis or blood fluke disease, also known as Bilharziasis, is a parasitic disease caused by helminths from a genus of trematodes entitled Schistosoma. It is a snail-borne trematode infection. The disease is among the Neglected Tropical Diseases, catalogued by the Global Plan to combat Neglected Tropical Diseases, 2008-2015 and is considered by the World Health Organization (WHO) to be the second most socioeconomically devastating parasitic disease, next to malaria. WHO demonstrates that schistosomiasis affects at least 200 million people worldwide, more than 700 million people live in endemic areas, and more than 200.000 deaths are reported annually. It leads to the loss of about 4.5 million disability-adjusted life years (DALYs).
