Download Improving Fish Stock Assessments Book in PDF, Epub and Kindle
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 Sustaining Marine Fisheries Book in PDF, Epub and Kindle
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.

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. Tables and figures. This is a print on demand report.

"Fish stock assessments provide the quantitative scientific information required by resource managers to determine stock status and set annual catch limits to prevent overfishing (Mace et al. 2001). Thus, assessments for managed fish and shellfish stocks represent an important core activity of the National Marine Fisheries Service (NMFS). Well-established procedures for these assessments have been developed to utilize data from fishery catch monitoring, fishery-independent surveys of abundance, biological studies, and other sources to produce the highly focused deliverables required by the Magnuson-Stevens Act (MSA). These data collection and analysis activities constitute a significant portion of the NMFS budget, but resources are insufficient to assess all managed stocks each year (nor is this a realistic target). It is therefore important to provide a transparent, quantitative, and objective process for determining what appropriate assessment targets are, and how to best meet those targets by determining priorities for assessment"--Executive summary.

Download Review of Northeast Fishery Stock Assessments Book in PDF, Epub and Kindle
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.
