"A population census was conducted to provide an estimate of population numbers of mature emergent abalone in areas near Malcolm Island, British Columbia during October 5-7, 1999. The abalone encountered in these surveys were generally large and most were dispersed, even though the habitat was extensive and appeared ideal for abalone. The estimated mean density for abalone of all sizes was 0.05/m² at Cormorant Island, 0.04/m² at Bere Bay, and 0.03/m² at Trinity Bay. The estimated mean total population number (and 90% confidence interval) for all sizes at Cormorant Island was 3636 (2608 - 4620), at Bere Bay was 5034 (3522 - 6640), and at Trinity Bay was 4089 (3027 - 5048) emergent abalone. The mean total population number (and 90% confidence interval) in the 120 - 140 mm SL size range was estimated for Cormorant Island to be 909 (674 - 1212), for Bere Bay to be 4075 (2654 - 5412), and for Trinity Bay to be 2516 (2121- 2979) emergent abalone. The low densities indicate that the removal of any abalone from these areas must be considered with caution"--Abstract, page iii. Includes abstracts in English and French.
