Lake Victoria Fisheries Resources


Book Description

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.




Lake Victoria


Book Description

This book constitutes a pioneering and unique work on Lake Victoria. It is the world’s second largest fresh-water lake and supports the livelihood of more than 30 million people. Surprisingly, there has been no comprehensive book addressing its problems and potentials. Ecology, environmental pollution and resource management are some of the issues addressed by this comprehensive insight into the limitations, challenges and opportunities facing Lake Victoria.




The Impact of Species Changes in African Lakes


Book Description

This important book covers the impact of species changes engendered by the introduction of fish species, impoundment and heavy exploitation. Aspects considered include reduction of biodiversity, the conservation of unique endemic fauna, the assessment of changes in habitat, species and genetic diversity, the evaluation of economic wealth generated by new fisheries, sustainability and social equity, and comparative forecasts from a range of management scenarios.




The Ecosystem Approach to Fisheries


Book Description

"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.




Management and Ecology of Lake and Reservoir Fisheries


Book Description

In this comprehensive edited book, international experts infisheries management and ecology review and appraise the status oflake and reservoir fisheries, assessment of fisheries yields,trophic ecology, rehabilitation and conservation, including aspecial section on African lakes where so much information of hugerelevance to fisheries managers is now available. Contributions from around the world. Carefully edited by internationally respected editor. Has been generated from acclaimed HIFI Symposium.




Report of the First Lake Victoria Fisheries Organization and FAO Regional Technical Workshop on Fishing Effort and Capacity on Lake Victoria


Book Description

The main objectives of the workshop were to raise the importance of managing fishing capacity and effort and discuss strategies that may be used to reduce capacity where necessary as part of taking measures for ensuring long-term sustainable utilization of the fishery resources of Lake Victoria; to develop and agree on mechanisms for assessing overall capacity on the entire lake; and to highlight the linkages between the management of fishing effort, capacity, and concomitant IUU fishing. The results of the workshop include actions for progressing work on the management of fishing capacity as well as guidance for the development of a Regional Plan of Action for the Management of Fishing Capacity on Lake Victoria. This document contains the report of the workshop as well as the papers and input provided by the participants. This document, and in particular, the actions adopted by the workshop participants can serve as a basis for further work aimed at improving regional fisheries management and the management of fishing capacity







Fish Stocks and Fisheries of Lake Victoria


Book Description

"The results of eighteen years research on the fisheries of Lake Victoria are presented here in a single volume. The introduction is followed by sections dealing successively with fish and fisheries, methodologies for sampling, gear and boats, methods for monitoring fish stocks, management and processing of data, fishery statistics and methods for monitoring the fishery. It, therefore, proceeds logically from fish to fisherman, passing through the scientific administrative steps needed to acquire and interpret the data necessary to ensure good management. The main body of the text is complemented by appendices which provide specific biological information on the major fish species of Lake Victoria, including a detailed key."--BOOK JACKET.




Review of the state of the world fishery resources: Inland fisheries


Book Description

The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.
