The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Preface The science and management of marine fisheries depend upon having clear and well-documented information. The task of collecting and maintaining this information falls to the National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Admin- istration. This task is daunting given that the type and volume of information continually expand along with the needs of fisheries man- agers to formulate more timely and area specific management actions. The National Research Council (NRC) has provided many fisheries and fisheries-related reviews in the last decade for Congress and NMFS. These reviews have included a summary review of the science, data, models, and processes used to guide NMFS resource management (National Research Council, 2002); an examination of how to address the legal mandate to use the best scientific information available in fisheries management (National Research Council, 2004); and a critical look at improving the collection, management, and use of marine fisheries data (National Research Council, 2000). The current report is in response to a request from NMFS for a review of the methods used to collect and analyze recreational marine fisheries data for application to fisheries management. While recreational fisheries have long been an important component of marine fisheries resource utilization, increased fishing pressure on many stocks has heightened the demand for information from all sources. At the same time, it has become increasingly complex and challenging to assess the catch and effort associated with recreational angling. The committee recognizes that NRC reviews add new tasks to NMFS's already hectic schedule, and we appreciate the information and responsiveness to requests that NMFS personnel provided. In particular, we thank Dr. David Van Voorhees, chief of the Fisheries Statistics Division, for his patience and openness in addressing questions about the vii
viii PREFACE program, and Dr. Steve Murawski, director of the Office of Science and Technology, for setting the stage for this review. The committee also recognizes the important contribution made to this report by many individuals from regional councils, state fisheries agencies, recreational and commercial fisheries organizations, environ- mental conservation organizations, and others who attended and pro- vided input to our deliberation. The people who made presentations to the committee are listed in the acknowledgments. Finally, the committee sincerely thanks the NRC staff for their valu- able support and extra efforts to facilitate the rapid completion of the report without compromising quality: David Policansky and Christine Blackburn (study directors), Susan Park (associate program officer), Jodi Bostrom (research associate), Carrie Wall (student volunteer), and Phillip Long (program assistant).
