Presents findings of transect surveys conducted to determine the density of the northern abalone, Haliotis kamtschatkana, from intertidal to approximately eight-metre depths, in a group of islands off the central British Columbia coast during May 1997. Results presented include mean abalone sizes versus depth, abundance of adult and juvenile abalone, and mean abalone densities versus depth.

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.
