Quota options for the geoduck clam (Panopea abrupta) fishery in British Columbia for 2001 and 2002 [electronic resource] / C.M. Hand and D. Bureau. Ottawa : Fisheries and Oceans Canada, 2000. 52 p. : fig., graphs, maps, tables. Canadian Stock Assessment Secretariat research document, 1480-4883 ; 2000/163 Includes bibliographic references (p. 22-25). Quota options for each geoduck bed are calculated as the product of estimates of virgin biomass and a target harvest rate. Biomass is calculated from estimates of bed areas, an estimated mean virgin density and a mean weight per individual. Quotas vary over time as new information is incorporated into calculations for virgin biomass. The objectives of this PSARC Working Paper are to update the time-series of fishery information with data from the 1998 and 1999 seasons, present new estimates of geoduck density from fishery-independent surveys and new estimates of mean geoduck weight from harvest log data, and to provide quota options by Geoduck Management Area (GMA) for the 2001 and 2002 fishing rotations. gccst Fisheries resources gccst Molluscs gccst Fishing area gccst Fisheries management Bureau, D.
