This work is concerned with the ecology of exploited fish populations. It takes a broad view of the subject, including a consideration of fish as elements in a delicately-balanced ecosystem. It also discusses the economics of fisheries in terms of a throughput of both energy and finance.

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.

If judged by a dismaying track record, and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention. Fish communities are shifting towards small rapid-growing species. These symptoms have been accopmanied by a series of fisheries collapses that have not only been largely unforeseen by our most advanced assessment methods, but have also brought about disastrous economic consequences. Such things have even occurred in Canada, a nation with probably more top-rate fishery scientists "per capita" than any other. So fisheries science is now in a state of flux, and many feel it is at a cross-roads where new paradigms compete for attention and demand evidence of their utility. This book is organized into five section: why does fisheries managment need reinventing?; new policies for a reinvented fisheries management; the role of the social sciences in a reinvented fisheries mangagement; coping with ecology in a reinvented fisheries management; and modelling through in a reinvented fisheries management.

Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention, with many of the world leaders in this area holding the view that no fishery has ever been properly understood or managed. With fisheries science in a state of flux, this extremely important book seeks a new paradigm that will place this flux of ideas in perspective and help us to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: Why does Fisheries Science Need Reinventing?; New Policies; The Role of the Social Sciences; Ecology; Modelling. Carefully integrated and edited by three of the world's leading fishery scientists, this stimulating book should find a place on the shelves of all fishery scientists throughout the world. It will be an invaluable reference source to those studying fish biology, fisheries and oceanography and all those involved in fisheries policy decisions in government and university research establishments.
