"The legal harvest of Northern Abalone, Haliotis kamtschatkana, was closed in 1990 due to population declines and subsequent conservation concerns. Northern Abalone has been monitored at index sites along the East Coast of Haida Gwaii (ECHG) and the Central Coast (CC) Regions of British Columbia by Fisheries and Oceans Canada (DFO) since 1978. In response to conservation concerns, surveys were expanded to include the West Coast of Vancouver Island (WCVI) Region in 2003, the Queen Charlotte Strait (QCS) Region in 2004, and the West Coast of Haida Gwaii (WCHG) Region in 2008. This report presents survey data collected for each of these Regions since either 2000 or the initiation of the survey and includes the results of analysis using a hurdle gamma Bayesian model to examine long-term trends in the population and distribution within each Region"--Abstract, p. iii.
