"Stock assessment surveys of the Giant Red Sea Cucumber, Parastichopus californicus, population in British Columbia have been ongoing since 1998. Between June 2013 and May 2014, three surveys were conducted to provide managers with population density and biomass estimates. The relative abundances of Geoduck (Panopea generosa), Red Sea Urchin (Strongylocentrotus franciscanus), and Green Sea Urchin (Strongylocentrotus droebachiensis) were also determined and are presented here. The Sidney – Sooke survey results showed low sea cucumber densities with all subareas having densities below 2.50 c/m-sh. The Laredo Channel and Queens Sound surveys had higher sea cucumber densities, however all subareas were below the regional baseline density”--Abstract, p. x. Issued also in print format.
