Distribution and biomass of the red sea cucumber, Parastichopus californicus (Stimpson), found in inlets of north British Columbia / by K.E. Cripps and A. Campbell. : Fs97-6/2300E-PDF

"Population numbers and harvestable biomass of the sea cucumber, Parastichopus californicus (Stimpson) were surveyed, within a depth range of 0 to 15.24 m chart datum in six inlets of the north coast of British Columbia. The estimated mean split-weight biomass per km of shoreline ranged from 2.8 to 6.4 t km⁻¹. Sea cucumbers were found most frequently on hard complex substrates and least frequently on soft substrates. At depths surveyed, sea cucumbers were most abundant in depths between 1 to 2 m below which densities generally declined with depth. Drained eviscerated weight varied between survey locations, reflecting different population size structures, however, the percentage of perivisceral fluids, muscle, and skin, in relation to total weight, were similar between areas"--Abstract, page iii.
