This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Book excerpt: 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.

This book was released on 2003-11-14 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been growing interest in having fisheries stakeholders involved in various aspects of fisheries data collection and experimentation. This activity is generally known as cooperative research and may take many forms, including gear technology studies, bycatch avoidance studies, and surveys. While the process is not new, the current interest in cooperative research and the growing frequency of direct budgetary allocation for cooperative research prompted this report. Cooperative Research in the National Marine Fisheries Service addresses issues essential for the effective design and implementation of cooperative and collaborative research programs.
Download or read book Management Science in Fisheries written by Charles T.T. Edwards and published by Routledge. This book was released on 2016-02-26 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key goal of fisheries management is to regulate extractive pressure on a resource so as to ensure social, economic and ecological sustainability. This text provides an accessible entry point for students and professionals to management science as developed in fisheries, in order to facilitate uptake of the latest ideas and methods. Traditional management approaches have relied upon a stock assessment based on existing understanding of resource status and dynamics, and a prediction of the likely future response to a static management proposal. However all such predictions include an inherent degree of uncertainty, and the last few decades have seen the emergence of an adaptive approach that uses feedback control to account for unknown future behaviour. Feedback is achieved via a control rule, which defines a relationship between perceived status of the resource and a management action. Evaluations of such rules usually include computer simulation testing across a broad range of uncertainties, so that an appropriate and robust rule can be selected by stakeholders and managers. The book focuses on this approach, which is usually referred to as Management Strategy Evaluation. The book is enriched by case study examples from different parts of the world, as well as insights into the theory and practice from those actively involved in the science of fisheries management.

Download or read book Fishery Science and Management written by Warren S. Wooster and published by Springer. This book was released on 2014-11-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
