A survey of red sea urchin populations was conducted in Beaver Pass and Freeman Pass (Pacific Fisheries Management sub-area 5-10 and 5-12) during May 2002. A total of 60 transects were surveyed by SCUBA divers, and 1243 red sea urchins were measured. Estimated mean densities (number/m²) and biomass (g/m²) were compared for red sea urchins found inside (18 transects) and outside (34 transects) previously fished commercial bed areas, and in research bed areas (8 transects). Densities were also compared by depth.
