Behold the cormorant: silent, still, cruciform, and brooding; flashing, soaring, quick as a snake. Evolution has crafted the only creature on Earth that can migrate the length of a continent, dive and hunt deep underwater, perch comfortably on a branch or a wire, walk on land, climb up cliff faces, feed on thousands of different species, and live beside both fresh and salt water in a vast global range of temperatures and altitudes, often in close proximity to man. Long a symbol of gluttony, greed, bad luck, and evil, the cormorant has led a troubled existence in human history, myth, and literature. The birds have been prized as a source of mineral wealth in Peru, hunted to extinction in the Arctic, trained by the Japanese to catch fish, demonized by Milton in Paradise Lost, and reviled, despised, and exterminated by sport and commercial fishermen from Israel to Indianapolis, Toronto to Tierra del Fuego. In The DevilÕs Cormorant, Richard King takes us back in time and around the world to show us the history, nature, ecology, and economy of the worldÕs most misunderstood waterfowl.

The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
