5203 |a"A survey of red sea urchin populations in the portion of Johnstone Strait near Kelsey Bay, parts of Pacific Fishery Management (PFM) Areas 12 and 13, was conducted in August 1999. A total of 74 transects were surveyed by SCUBA divers. Densities and biomass were estimated on a per PFM sub-area basis. In PFM area 12, estimated mean density ranged from 0.43 to 0.81 urchins per m², overall mean density was 0.59 urchins per m². In PFM area 13, estimated mean density ranged from 0.52 to 2.68 urchins per m², overall mean density was 1.79 urchins per m². Estimated mean biomass ranged from 226.4 to 320.2 g per m² and overall mean biomass was 265.3 g per m² in PFM area 12. Biomass ranged from 183.9 to 933.9 g per m² and overall biomass was 718.5 g per m² in PFM area 13. Overall, 8.1% of the total urchins measured were ≤50mm test diameter (TD) whereas 65.3% of urchins were of legal size (≥100mm TD) for the commercial fishery"--Abstract, page iii.
