Includes bibliographical references (pages 9-10). "During the period April 24-28, 1980 we dove at 12 sites in the vicinity of Emily Carr Inlet and in the large bay at the south end of Lotbiniere Island in the Estevan Group. Commercial abalone populations were absent from Emily Carr Inlet, although the habitat appeared to be suitable. The area has been closed since the commercial abalone fishery began in this area, and the density and size structure of abalone suggest that harvesting is not responsible for the scarcity of abalone. In Lotbiniere Bay, we found that a heavily harvested commercial bed still supported a good commercial density of abalone. The density of sub-legal abalone within one year's growth of attaining legal size suggested that the rate of recruitment to the fishery is excellent on this bed, but the remainder of the size structure and the appearance of the shells cast some doubt on this conclusion. Because of the high variance in abalone density among sites, and the difficulty of returning to exactly the same spot at each survey, it is not possible to see any trend in densities observed over the period that this area has been surveyed"--Abstract, page iii.
