Biomass estimates for Sea Cucumbers (Parastichopus californicus, Cucumaria miniata, C. pallida) as determined through surveys conducted June 2011 to May 2012 / by N.M.T. Duprey.: Fs97-4/3017E-PDF

"Stock assessment surveys of the Giant Red Sea Cucumber, Parastichopus californicus, population in British Columbia have been ongoing since 1998. Between June 2011 and May 2012, eight 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 Howe Sound, Louise Island, and Cowichan Bay survey results showed low sea cucumber densities, with many Subareas having densities below the established commercial fishery threshold. The Texada–Lasqueti, Desolation Sound, Seymour Inlet, and Belize Inlet surveys had higher sea cucumber densities, with most Subareas having densities above the commercial fishery threshold. Locations for no-take reserve areas are suggested"--Abstract, page xi.
