Includes bibliographical references (pages 42-43). "Stock assessment surveys of the sea cucumber, Parastichopus californicus, population in British Columbia have been ongoing since 1998. Between June 2010 and May 2011, six surveys were conducted to provide managers with population density and biomass estimates. The relative abundance of red sea urchin (Strongylocentrotus franciscanus), green sea urchin (Strongylocentrotus droebachiensis), and geoduck (Panopea generosa) were also measured and are presented here. The Area 3 North and Area 12 Sointula surveys did not have high sea cucumber densities with many Subareas lacking sufficient densities for a commercial fishery. The Princess Royal Channel (with Tolmie Channel habitat removed), Jervis Inlet – Sechelt and Area 18 South Gulf Island surveys had higher sea cucumber densities, with most Subareas having sufficient densities to support a commercial fishery. Locations for no-take reserve areas are suggested"--Abstract, page xi. Includes abstracts in English and French. Parastichopus californicus British Columbia Pacific Coast.
