5203 |a"As a result of over-exploitation, the legal harvest of northern abalone, Haliotis kamtschatkana, was closed in 1990. Since 1978, the Department of Fisheries and Oceans Canada has conducted periodic surveys of index sites along the coast of British Columbia (BC) to monitor the status of abalone populations. In 2001, the index sites along the central coast of BC were resurveyed. Two hundred and thirty abalone were measured at 40 (72.7%) of the 55 historic index sites surveyed. The overall density was 0.27 abalone/m²; the lowest density observed in the nine surveys of this area since 1978. Densities of mature (≥70 mm shell length) abalone were also at their lowest levels. Abalone ≥100 mm shell length were observed at only 25% of sites surveyed. Statistical comparisons were made for size and density across years. There was no evidence of abalone population recovery along the central coast. Poaching continues to be the main concern preventing the recovery of abalone populations in British Columbia"--Abstract, page vi.
