Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Download or read book Recruiting Fishery Scientists written by National Research Council and published by National Academies Press. This book was released on 2001-02-01 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS) employs many fishery scientists with diverse skills. The agency finds that the supply of fishery biologists is adequate to meet most of its demand. However, increasing demands on the agency to understand fish populations and the social and economic conditions in fishing communities have created a need for additional experts in the fields of fisheries stock assessment and social sciences. NMFS has developed plans for meeting its anticipated staff needs in stock assessment and social sciences and asked the National Research Council (NRC) to convene a workshop to discuss the plans and suggest other actions the agency might take to ensure an adequate supply of experts in these fields. Approximately 30 individuals gathered in Woods Hole, Massachusetts on July 17, 2000 under the auspices of the NRC's Ocean Studies Board to discuss NMFS' plans. This document summarizes the presentations and discussions at that one-day workshop. No attempt was made to reach consensus among the participants; thus, the suggestions recorded in this summary represent the personal views of workshop participants, as summarized by NRC staff.
Download or read book Review of Northeast Fishery Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-04-17 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collapse of cod, flounder, and haddock fish stocks in the Northeast United States has caused widespread concern among managers and fishers in the United States and Canada. The diminishing stocks have forced managers to take strict regulatory measures. Numerous questions have been raised about the adequacy of stock assessment science used to evaluate the status of these stocks and the appropriateness of the management measures taken. Based on these concerns, Congress mandated that a scientific review of the methodology and data used to evaluate these stocks be conducted. In this volume, the committee concludes that although there are improvements to be made in data collection, modeling uncertainty, and communicating between fishers, managers, and scientists, the scientific methods used in the Northeast stock assessments are sound. Recommendations are made on how the stock assessment process can be improved.
Download or read book Fish Stock Assessments written by Anne-Marie Fennell and published by . This book was released on 2014-10-22 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. marine fisheries contribute over $100 billion annually to the American economy and provide recreational fishing opportunities to millions of Americans. To continue enjoying these benefits, the Nat. Oceanic and Atmospheric Admin. (NOAA) manages marine fish stocks to ensure their sustainable use. NOAA's National Marine Fisheries Service (NMFS) is responsible for fishery conservation and management, including fish stock assessments to estimate the size of the population of a fish stock and to examine whether a stock is overfished and provide support for management measures. This report (1) identifies differences in the number and frequency of fish stock assessments conducted by NMFS' regional fisheries science centers and the causes of those differences; (2) identifies how NMFS sets priorities for conducting fish stock assessments; (3) determines the funding NMFS receives annually for conducting fish stock assessments; and (4) determines how NMFS makes funding decisions to support fish stock assessments.

Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 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 Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.

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 2004-10-03 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.
Download or read book Robust Methods for the Analysis of Images and Videos for Fisheries Stock Assessment written by National Research Council and published by National Academies Press. This book was released on 2015-02-24 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS) is responsible for the stewardship of the nation's living marine resources and their habitat. As part of this charge, NMFS conducts stock assessments of the abundance and composition of fish stocks in several bodies of water. At present, stock assessments rely heavily on human data-gathering and analysis. Automatic means of fish stock assessments are appealing because they offer the potential to improve efficiency and reduce human workload and perhaps develop higher-fidelity measurements. The use of images and video, when accompanies by appropriate statistical analyses of the inferred data, is of increasing importance for estimating the abundance of species and their age distributions. Robust Methods for the Analysis of Images and Videos for Fisheries Stock Assessment is the summary of a workshop convened by the National Research Council Committee on Applied and Theoretical Statistics to discuss analysis techniques for images and videos for fisheries stock assessment. Experts from diverse communities shared perspective about the most efficient path toward improved automation of visual information and discussed both near-term and long-term goals that can be achieved through research and development efforts. This report is a record of the presentations and discussions of this event.
