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.

Available in PDF, EPUB and Kindle. Book excerpt: "Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.

Download or read book Limnology, Climatology and Paleoclimatology of the East African Lakes written by Thomas C Johnson and published by Routledge. This book was released on 2019-08-13 with total page 679 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.

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.

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.

Download or read book Governability of Fisheries and Aquaculture: Theory and Applications written by Maarten Bavinck and published by Springer Science & Business Media. This book was released on 2013-04-10 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following from Fish for Life – Interactive Governance for Fisheries (Kooiman et al., 2005), which presents an interdisciplinary and intersectoral approach to the governance of capture and aquaculture fisheries, this volume pursues what interactive governance theory and the governability perspective contribute to the resolution of key fisheries problems, these include overfishing, unemployment and poverty, food insecurity, and social injustice. Since these problems are varied and can be felt among governments, resource users and communities globally, the diagnosis must be holistic, and take account of principles, institutions, and operational conditions. The authors argue that ‘wicked problems’ and institutional limitations are inherent to each setting, and must be included in the analysis. The volume thereby offers a new lens and a systematic approach for analysing the nature of problems and challenges concerning the governance of fisheries, explores where these problems are situated, and how potential solutions may be found. ”It now seems clear that the crisis in the world’s fisheries [is] a much larger and more complex problem than many had imagined. Yet, examining it through the lens of governability may offer the best hope for alleviating it--as well as alleviating similar crises in other social systems.” James R. McGoodwin (Professor Emeritus, University of Colorado)
