Book Description
This volume is concerned with the role of science in fishery management. While this has traditionally been considered as largely a biological problem with clear biological objectives, close examination suggests that management decisions are largely controlled by political, social and economic considerations, biologically constrained. The biologist now has the task of reducing the uncertainties of the venture rather than determining its priorities or its allocation of benefits. The uncertainties arise in part because of lack of understanding of the ecological systems involved, the limited availability of critical information, and the unpredictability of driving forces. The volume reviews the assumptions and simplifications of fishery models, examines the decision making framework in fishery management, and compares management practices in North America, Japan, and Northern Europe. A compilation of fishery management objectives in international agreements and U.S. laws is included.

Book Description
Atlantic halibut and Pacific halibut off the Atlantic and Pacific coasts of North America share many biological characteristics. The conventional separation of the halibut into separate species is not uniformly accepted. Reproduction and early life history are nearly identical, although the extensive drift of Pacific halibut eggs and larvae and countermigration as juveniles have not been demonstrated for the Atlantic halibut. Adult halibut undergo migration from winter spawning grounds along the upper continental slope to summer feeding grounds on the continental shelf. The two halibuts show the same pattern of age and growth. They exhibit different trophic selectivity, as small Atlantic halibut consume a higher proportion of invertebrates as samll fish and large Atlantic halibut consume a higher proportion of fish, compared to Pacific halibut. Halibut management in the Atlantic and Pacific varies dramatically. Atlantic halibut in Canada were managed with other groundfish until 1988 and are not managed in the United States. Pacific halibut have been managed by an international commission under treaty between the United States and Canada since 1923. Atlantic halibut have produced from 1000 to 5000 t annually, mainly off Canada, while Pacific halibut have produced 12,000 to 45,000 t, mainly off Alaska. Biological and fishery data are collected more extensively for the Pacific halibut, for which detailed stock assessment is conducted.

Book Description
Based on original scientific material, this study traces the history of fish stock management (including whales and seals) up to recent times when problems of over-exploitation have had dramatic effects upon stocks.

Book Description
This book serves as an advanced text on fisheries and fishery population dynamics and as a reference for fisheries scientists. It provides a thorough treatment of contemporary topics in quantitative fisheries science and emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods. The analytical methods are accessible to a wide range of biologists, and the book includes numerous examples. The book is unique in covering such advanced topics as optimal harvesting, migratory stocks, age-structured models, and size models.

Book Description
How can we manage a so-called "renewable" natural resource such as a fishery when we don't know how renewable it really is? James A. Crutchfield and Arnold Zellner developed a dynamic and highly successful economic approach to this problem, drawing on extensive data from the Pacific halibut industry. Although the U.S. Department of the Interior published a report about their findings in 1962, it had very limited distribution and is now long out of print. This book presents a complete reprint of Crutchfield and Zellner's pioneering study, together with a new introduction by the authors and four new papers by other scholars. These new studies cover the history of the Pacific halibut industry as well as the general and specific contributions of the original work—such as price-oriented conservation policy—to the fields of resource economics and management. The resulting volume integrates theory and practice in a clear, well-contextualized case study that will be important not just for environmental and resource economists, but also for leaders of industries dependent on any natural resource.

Book Description
Environmental Markets explains the prospects of using markets to improve environmental quality and resource conservation. No other book focuses on a property rights approach using environmental markets to solve environmental problems. This book compares standard approaches to these problems using governmental management, regulation, taxation, and subsidization with a market-based property rights approach. This approach is applied to land, water, wildlife, fisheries, and air and is compared to governmental solutions. The book concludes by discussing tougher environmental problems such as ocean fisheries and the global atmosphere, emphasizing that neither governmental nor market solutions are a panacea.
