A survey was conducted during May 17-20, 2004, in Queen Charlotte and Johnstone Straits to estimate the distribution and density of emergent northern abalone (Haliotis kamtschatkana). The estimated mean density for emergent abalone of all sizes was 0.064 ± 0.022 abalone/m2 in Queen Charlotte Strait and 0.017 ± 0.014 abalone/m2 in Johnstone Strait. The mean shell length for both areas combined was 85.7 mm. This study was compared to two earlier surveys conducted in 1977 and 1986 in the same area, as well as recent surveys on other parts of the coast.

Index site surveys have been performed since 1978 to monitor abalone populations in British Columbia. This paper presents the results of the index sites survey in the south-east Queen Charlotte Islands in April 2002. Survey methods are described and findings from sampling at 68 historic index sites are presented & discussed with regard to numbers of abalone, mean shell length, density, and percent of sites with abalone. The abalone density estimates are compared with those measured in previous surveys.
