Available in PDF, EPUB and Kindle. Book excerpt: This book really began in 1980 with our first microcomputer, an Apple II +. The great value of the Apple II + was that we could take the computer programs we had been building on mainframe and mini-computers, and make them available to the many fisheries biologists who also had Apple II + 's. About 6 months after we got our first Apple, John Glaister came through Vancouver and saw what we were doing and realized that his agency (New South Wales State Fisheries) had the same equipment and could run the same programs. John organized a training course in Australia where we showed about 25 Australian fisheries biologists how to use microcomputers to do many standard fisheries analyses. In the process of organizing this and sub sequent courses we developed a series of lecture notes. Over the last 10 years these notes have evolved into the chapters of this book.

Download or read book Sustaining Marine Fisheries written by Committee on Ecosystem Management for Sustainable Marine Fisheries and published by National Academies Press. This book was released on 1999-03-05 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

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.

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 481 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 Sustainable Fishery Systems written by Anthony Charles and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.

Download or read book Improving the Use of the Best Scientific Information Available Standard in Fisheries Management written by National Research Council and published by National Academies Press. This book was released on 2004-09-03 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the Magnuson-Stevens Fisheries Conservation and Management Act (FCMA), managers are required to use the "best scientific information available" in the preparation of federal fishery management plans (National Standard 2 in the FCMA). However, the Act provides no further guidance as to how conformance to this standard should be determined. Because adherence to this standard has often been contentious, Congress has considered adding a definition for what constitutes "best scientific information available" in the reauthorization of the FCMA. This report examines both the current application and the controversy over the standard and concludes that a legislative definition would be too inflexible to accommodate regional differences and future advances in science and technology. Instead, the report recommends that NOAA Fisheries adopt procedural guidelines to ensure that the scientific information used in the development of fishery management plans is relevant and timely and is the product of processes characterized by inclusiveness, transparency and openness, timeliness, and peer review.

Available in PDF, EPUB and Kindle. Book excerpt: "The International Council for the Exploration of the Sea (ICES) is the central scientific network within the massive set of bureaucracies that is responsible for Europe's Common Fisheries Policy (CFP). While spending the past 25 years failing to sustain Europe's fish stocks, this management system also became adept at making the lives of its scientists miserable. Now it is being confronted by the complex challenge of an ecosystem-based approach to fisheries management. If this combination of a multi-national bureaucracy, hard politics, and scientific uncertainty has made it impossible to maintain many individual fish stocks, how are decisions going to be made that consider everything from sea birds to climate change? The old political saw that "if you can't solve a problem, make it bigger" has never been put to a test like this! Yet ICES has begun to rise in an impressive way to the scientific challenge of providing advice for an ecosystem approach within the world's most cumbersome fisheries management system. This book lays out the results of extensive sociological research on ICES and the decision making systems into which it feeds. ICES is finding ways to provide effective advice in the many situations where scientific advice is needed but a clear, simple answer is out of reach. In spite of the difficulties, scientists are beginning to help the various parties concerned with management to deal with facts about nature in ways that are more useful and transparent"--Publisher's description.

Download or read book Advances in Fisheries Science written by Andrew I. L. Payne and published by John Wiley & Sons. This book was released on 2009-01-22 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely book brings readers up to date on the wide range of advances made in fisheries science since the publication in 1957 of On the Dynamics of Exploited Fish Populations (Beverton and Holt), regarded by many fisheries scientists as one of the most important books on fisheries yet published. Traditional fishery subjects covered include historic declines and changes in fishing fleets, fisheries management and stock assessments, data-poor situations, simulation and modelling of fished stocks, fisheries economics, assessing reproductive potential and dispersal of larvae, fisheries for sharks and rays, and use of marine technology. Additionally, related subjects of increasing importance now that ecological approaches to management are coming to the fore are presented. They include benthic ecology, ecosystem changes linked to fishing, life history theory, the effects of chemicals on fish reproduction, and use of sounds in the sea by marine life. Several chapters offer stimulating philosophical discussion of the many controversial areas still existing. This significant book, edited by Andy Payne, John Cotter and Ted Potter and containing contributions by world-renowned fisheries scientists, including many based at Cefas (where Beverton and Holt's original work was carried out) is an essential purchase for fisheries managers and scientists, fish biologists, marine scientists and ecologists. Libraries in all universities and research establishments where fisheries and biological sciences are studied and taught are likely to need copies of this landmark publication.
