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.

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.

Integrated Analytical Approaches for Pesticide Management provides proven laboratory practices/examples and methods necessary to control pesticides in food and water in various environments. The book presents insights into good laboratory practices and examples of methods used in individual specialist laboratories, thus enabling stakeholders in the agri-food industry to appreciate the importance of proven, reliable data and the associated quality assurance approaches for end product testing for toxic levels of contaminant residues in food. The book is written in a rigorous, but simple, way to make sure that a broad range of readers can appreciate its technical content. The book's practical nature and generic guidelines distinguish it from others in the marketplace. Provides coverage of risk assessment and effective testing technologies Covers generic guidelines on pesticide analysis on different environmental matrices for use in the developed and developing world Presents the most up-to-date information in research sample testing preparation and method validation to detect pesticide residues in food Includes examples of each method for practical application Demonstrates proven, reliable research data and the associated quality assurance approaches for end product testing for food, water and soil sediment Describes the concept of integrated analytical approaches for pesticide management practices
