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.

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.

Stock Assessment: Quantitative Methods and Applications for Small Scale Fisheries is a book about stock assessment as it is practiced. It focuses on applications for small scale or artisanal fisheries in developing countries, however it is not limited in applicability to tropical waters and should also be considered a resource for students of temperate fishery management problems. It incorporates a careful sample design, various mathematical models as a basis for predicting consequences for stock exploitation, and discusses the impact of exploitation on non-targeted species. This was a unique concept involving a collaborative effort between U.S. and host country scientists to address issues of regional and global concern through innovative research. Unlike other books on stock assessment that show mathematical models, this is the only book of its kind that discusses how an assessment is carried out. It looks at the field as a whole and includes sampling, age determination and acoustics. The book represents the culmination of a nine-year program financed by the United States Agency for International Development to provide new or improved methods of stock assessment for artisanal fisheries.

Describes the scientific techniques used in assessing fish stocks, evaluating the effect of fishing on these stocks, and the probable impact of different policies for developing and managing fisheries. Covers the techniques developed starting with simple models and continuing to more complex methods.

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.

This report provides an overview of the biological status of assessed stocks around the world and relates measures of stock status to the strength of fisheries management. Stock assessment outputs, consisting primarily of time series of abundance and fishing pressure relative to target reference points, were compiled for 548 marine fish and invertebrate stocks in the RAM Legacy Stock Assessment Database. Data summary methods included: global and regional mean trends of abundance and fishing pressure relative to target reference points; bivariate plots of relative abundance and fishing pressure; estimates of potential equilibrium yield foregone at current fishing pressure; and proportions of stocks in different biomass status categories. These measures of stock status were summarized at the global level as well as separated by 16 FAO Major Fishing Areas and ocean basin regions for comparison.

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.
