The Impact of Species Changes in African Lakes (Fish & Fisheries Series Book 18)

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.

The editors of this interdisciplinary book, well known for their work in fisheries ecology, have brought together a wealth of information from many internationally recognized scientists. 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 Impact of Species Changes in African Lakes will be of great use and interest to scientists across a wide range of disciplines, including fish biologists and fisheries workers, ecologists, conservationists and environmental scientists, and all those involved in work on introductions, economics of natural resources and development of fisheries.
