Arnold Hansen Director Marine Technology Centre Trondheim Norway Norwegian fisheries are presently facing serious problems, but also some promising challenges. Most important is the fact that nearly all the major fish stocks have been over-exploited, either by an overall too large fishing effort or a too large effort on wrong year-classes, resulting in stock-sizes reduced well below an economically optimum level or even nearly depleted. The atlanto-scandic herrings, for instance, has been below an exploitable level for several years. The recommended total allowable catch of Norwegian-Arctic cod for 1980 is 390,000 tons compared to more than 800,000 tons a few years ago. The Norwegian industrial fisheries are today mainly based on capelin. The Soviet Union has successfully claimed an increased share of this resource, resulting in an accordingly reduced catch quota for the Norwegian purse seining fleet. As a result of this resource situation the excess catching and processing capacity is great. Maintaining this excess capacity means high production costs. Both short term and long term planning for a better capacity adoption to the resources are necessary, as are means of policy to obtain this goal. (In other words fishery management is a neces sity. ) Generally speaking the fishing industry is energy intensive. Fuel prices have increased dramatically the last year. Further increases may be expected as we gradually change from the present politically based situation of a non-realized excess crude oil production capacity into a real shortage of oil fuels.

Over eleven years have passed since the last NATO sponsored meeting on Fishing which took the form of a Conference held in Trondheim in 1979. The proceedings contained in this book consist of papers presented in support of an Advanced Study Institute on Operations Research and Management in Fishing held at P6voa de Varzim, Portugal from March 25 to April 7 1990. It was originally intended to use the five themes, Production Functions and Management; Marine Fish Stocks; Fisheries Models; Fish Farming and Miscellaneous. There were no contributions on Fish Processing and the Fish Farming papers were not original. It was also decided to group the papers on Fisheries Models and Marine Fish Stocks together which means the proceedings has four headings: - Opening Session - Production Functions and Management - Marine Fish Stocks and Fisheries Models - Miscellaneous The contributions give a broad and complete overview of historical approaches and of recent trends on research in different sectors of fisheries. Criteria for quota distribution and schemes based on conclusions drawn from models and methods are presented. Surveillance methods are described in relation to species conservation and catch improvement. Different levels of regulatory enforcement are discussed and the implications of new technologies are introduced. Applications of Expert Systems to stock assessment and efficiency improvement in field sampling are presented. Models for fleet dispatch planning and fleet structure appraisal are introduced and procedures for operational capacity evaluation of fishery harbours are considered.

The use of operations research (OR) in natural resources management (NRM) is an evolving research field with many application areas. Decision makers in NRM are often not aware of the possibilities that OR techniques offer them to solve their daily challenges. This special issue contributes to close this gap by showing how OR can be useful in different application areas of NRM.

Here is the first systematic handbook treatment of quantitative modeling natural resource problems, their allocated efficient use, and societal and economic impact. Andrés Weintraub is the very top person in Natural Resource research. He has selected co-editors who are at the top of the sub-fields in natural resources: agriculture, fisheries, forestry, and mining. The book covers these areas with contributions from researchers on, among others, modeling natural research problems, quantifying data, and developing algorithms.

This report describes and evaluates the impact of the major changes in the management of Canada's marine fisheries in recent decades. The report covers the historical and jurisdictional context; biological and economic aspects; objectives of fisheries management; techniques of resources management in general and those used for specific species; managing the common property through allocation of access, limited entry licensing, and individual quotas; the international dimension; the social dimension; habitat management; fisheries enforcement; and fisheries management in the United States, Australia, New Zealand, Norway, Iceland, and the European Community.

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.

A true landmark publication, Advances in Fisheries Economics brings together many of the world’s leading fisheries economists to authoritatively cover the many issues facing the field of fisheries economics and management today. Compiled in honour of the work and achievements of Professor Gordon Munro of the University of British Columbia, Canada, this exceptional volume of research serves as both a valuable reference tool and fitting tribute to a man whose work has shaped the discipline. Divided into four sections, the text includes coverage of: • Property Rights and Fisheries Management • Capital Theory and Natural Resources • Game Theory and International Fisheries • Applied Fisheries Economics and Management The book is an important addition to the resources of all fisheries economists, managers, scientists and fish biologists. Libraries in universities and research establishments where these subjects are studied and taught should have copies on their shelves.

This book is presented in seven Chapters. Chapter 1 describes the basic assumptions underlying the optimal allocation of natural resources and the inherent characteristics of fisheries that determine, under unrestricted access, the failure to allocate resources, economic inefficiency and overfishing. To mitigate these undesired effects, the bioeconomic literature invokes the allocation of property rights, which in turn must be implemented within a management context. Thus, in this Chapter we suggest some guidelines to conduct management plans. Static and dynamic bioeconomic models are presented in Chapter 2 as a theoretical framework for the design of intelligent management schemes aiming at sustainable use of fish stocks. Classic models are shown, such as the Gordon-Schaefer based on the logistic. We also develop new bioeconomic approaches, such as a distributed-delay model to add realism to Smith's fleet dynamics approach. Chapter 2 also includes an introductory version of a bioeconomic yield-mortality model, and dynamic age-structured models. A comparison of the dynamic and static trajectories is stressed. The price of time and its implications for optimal resource allocation over time is also discussed. For the sake of adding realism to the above models, the systems approach is used in Chapter 3 to model different technological and ecological complexities that occur in marine fisheries. Ecological interdependencies (competition, predation), as well as technological interdependencies resulting from fleets with different fishing power and/or gear types, operating on components of a stock, or on different target species of a "mixed stock", are specified and modelled.
