Sablefish stock assessment for 2000 and recommended yield options for 2001 [electronic resource] / V. Haist and R. Hilborn. Ottawa : Fisheries and Oceans Canada, 2000. 74 p. : fig., graphs, maps, tables. Canadian Stock Assessment Secretariat research document, 1480-4883 ; 2000/157 Includes bibliographic references (p. 15-17). This document represents a major assessment for B.C. sablefish. The document is comprised of five sections, the first of which summarizes fishery and biological information. The next three sections describe three alternative methods that are used to estimate B.C. sablefish abundance. All three methods utilize tag release and recapture data, which has been the primary indicator of sablefish abundance trends since the 1995 assessment. Prior to that time commercial catch per unit effort (CPUE) was used as a tuning index, but concern that CPUE did not reflect true abundance trends led to the development of assessment methods based on the tag-recapture data. The final section of the document presents results of stock projections. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Hilborn, Ray. Canada.
