"This Goose Barnacle Framework updates a general framework for Goose Barnacles (CaɁinwa;1Pollicipes polymerus) in waters off the West Coast of Canada developed by Lauzier in 1999. The update incorporates a revised survey methodology and analytical procedures for estimating goose barnacle bed area and biomass with the inclusion of Local Ecological Knowledge (LEK). Bed area can now be mapped and estimated using advances in Global Positioning System (GPS) technology and Google Earth Mapping Software. New analytical procedures using bootstrapping methodology and LEK are proposed for quantitatively estimating Goose Barnacle biomass. This paper explores the concept of using harvest area closures as an alternative to a biologically-based provisional Limit Reference Point (LRP) and an Upper Stock Reference (USR). The new methodologies are documented and results of recent surveys using the new methodologies are presented."--Abstract, p. iv.
