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.

"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.

"The purpose of the Workshop was to present the assessment results and management advice on weakfish, surfclams, striped bass, and spiny dogfish, peer reviewed by the Stock Assessment Review Committee at its December 1-5, 1997 meeting, to managers, fisheries representatives, and the public"--Introduction.

"The Northeast Regional Stock Assessment Workshop (SAW) process has three parts: preparation of stock assessments by the SAW Working Groups and/or by ASMFC Technical Committees / Assessment Committees; peer review of the assessments by a panel of outside experts who judge the adequacy of the assessment as a basis for providing scientific advice to managers; and a presentation of the results and reports to the Region's fishery management bodies. Starting with SAW-39 (June 2004), the process was revised in two fundamental ways. First, the Stock Assessment Review Committee (SARC) became smaller panel with panelists provided by the Independent System for Peer Review (Center of Independent Experts, CIE). Second, the SARC provides little management advice. Instead, Council and Commission teams (e.g., Plan Development Teams, Monitoring and Technical Committees, Science and Statistical Committee) formulate management advice, after an assessment has been accepted by the SARC. Starting with SAW-45 (June 2007) the SARC chairs were from external agencies, but not from the CIE. Starting with SAW-48 (June 2009), SARC chairs are from the Fishery Management Council's Science and Statistics Committee (SSC), and not from the CIE. Also at this time, some assessment Terms of Reference were revised to provide additional science support to the SSCs, as the SSC's are required to make annual ABC recommendations to the fishery management councils"--Foreword.
