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.

Afro-Eurasia: Assessing Sustainability focuses on the geographic area where humans originated and first began to make use of the natural world - Earth's largest landmass, stretching from Portugal in the west across the steppes of Russia and south across Africa to the Cape of Good Hope. By examining the history of human expansion, as well as 21st century pressures to address ecosystem damage across the region, international scholars and regional experts weave sustainability into core curricular subjects. The interdisciplinary coverage includes national and regional environmental histories, as well as business and commerce, migration, educational institutions, law and government, and the lifestyles of diverse populations.

Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.
