Book Description
The African lakes are an extremely important ecosystem and the subject of much study relating to species introductions and loss of biodiversity. This book provides a thorough review of the whole subject and will be of great interest to fish biologists, fisheries workers, ecologists, environmental scientists and conservationists.

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.

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.

Book Description
This book focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years) to synthesize evidence of climate variability at the regional and continental scale across Europe and Africa. This is the first examination of historical climate variations at such a scale, and thus sets a benchmark for future research.

Book Description
Gills of healthy fishes are their lifeline to meet the challenges arising from their changing environment: oxygen gradient, alkalinity, temperature fluctuations and the added pollutants. The diverse and ever changing aquatic environment has a major impact on the organization of various organ-systems of fishes. This book contains seventeen chapters

Book Description
Annotation In this mesmerizing series of interviews with dedicated people who work to save endangered species throughout the world, an alarming truth emerges: the obstacles of human politics, greed, corruption, folly, and hypocrisy can present as much danger to a species' survival as biological causes. The dramatic lessons of this book shed new light on the problems of declining species and offer hope that we may yet change their fate.
