Book Description
There is overwhelming evidence that marine resources are being overexploited throughout the world. In an effort to conserve the natural resources of the world’s oceans, new methods, technologies, and practices in fishery and marine resource management must be implemented. Progressive Engineering Practices in Marine Resource Management combines scientific, ecological, and engineering approaches involved in the sustainable management of natural resources. Featuring coverage on key topics relating to environmental management, maritime spatial planning, sustainable fisheries, and waste water treatment, this publication is a critical reference source for fishery associations, scientists, environmental management authorities, and water management directorates interested in emerging technologies and innovative resource management techniques.

Book Description
The world’s stocks of wild fish continue to decline, making the task of finding innovative, sustainable and socially acceptable methods of fisheries management more important than ever. Several new approaches from around the world have proved to be successful in stemming the decline whilst increasing fish catches, and under the editorship of McClanahan and Castilla this international team of authors have looked to these examples to provide the reader with carefully chosen case studies offering practical suggestions and solutions for problem fisheries elsewhere. Coverage includes: Community based fisheries Collaborative and co-operative fisheries management Coastal fisheries management The future for sustainable fisheries management Written by many of the world’s most experienced practitioners Fisheries Management: Progress toward sustainability is an important purchase for all fisheries scientists, managers and conservationists. All libraries in universities and research establishments where this area is studied and taught will find this book a valuable addition to their shelves.

Book Description
As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. Namibia's Fisheries is a timely contribution to this discussion as it examines Namibia's Benguela upwelling system, an area that supports traditional and modern forms of fishery. This volume analyzes the Namibian experience in fishery management, featuring essays by researchers, Namibian fishery managers, and international specialists that cover a range of ecological and social issues. Namibia's Fisheries will be a valuable resource for researchers, conservationists, and students of fishery management.

Book Description
Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Book Description
Mathematical demography is the centerpiece of quantitative social science. The founding works of this field from Roman times to the late Twentieth Century are collected here, in a new edition of a classic work by David R. Smith and Nathan Keyfitz. Commentaries by Smith and Keyfitz have been brought up to date and extended by Kenneth Wachter and Hervé Le Bras, giving a synoptic picture of the leading achievements in formal population studies. Like the original collection, this new edition constitutes an indispensable source for students and scientists alike, and illustrates the deep roots and continuing vitality of mathematical demography.
