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.

Cichlid fishes are amazing creatures. In terms of sheer number of species, they are the most successful of all families of vertebrate animals, and the extent and speed with which they have evolved in some African lakes has made them the darlings of evolutionary biologists. But what truly captivates biologists like George Barlow -- not to mention thousands of aquarists the world over -- is the complexity of their social lives and their devotion to family (most species of cichlids are monogamous and many pairs share the responsibility of raising offspring). In this wonderful book, Barlow describes the unusually high intelligence of these fishes, their complex mating and parenting rituals, their bizarre feeding and fighting habits, and the unusual adaptations and explosive rate of speciation that have enabled them to proliferate and flourish. A celebration of their diversity, The Cichlid Fishes is also a marvelous exploration of how these unique animals might help resolve the age-old puzzle of how species arise and evolve.

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 large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the climatologists, geologists, paleolimnologists, and biologists displayed their results and debated interpretations, it appeared that some paradigms were shifting, and that new explanations of climate history and modem processes were taking shape. The Steering Committee endorsed the production of a volume that would draw together the different research results that were emerging and which would be representative of the scope of science issues that exist within IDEAL. This book follows in the spirit of The Limnology, Climatology, and Paleoclimatology of the East African Lakes, published in 1996, but has a somewhat different purpose. The previous publication also included original science results, but it was conceived to review the state of knowledge, identify critical problems, and point to new paths of inquiry. It accompanied the development of our first Science and Implementation Plan for the East African Lakes.
