The Abalone Recovery Team has completed a recovery strategy for the northern abalone (Haliotis kamtschatkana). The abalone is a marine mollusc related to snails and whelks that has been declining in numbers and distribution in surveyed areas of British Columbia (BC) since the late 1970s. Declines in abundance by more than 75% prompted the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) to list the abalone as threatened in 1999. In June 2003, abalone were legally protected under the new Species At Risk Act (SARA), prohibiting killing, harming, harassing, capturing and taking abalone, and damaging abalone residences and critical habitat.
This newsletter provides an update on recent abalone recovery activities since August 2003.
Fisheries & Oceans
Parks researchers have focused on abalone habitat, and found that abalone prefer shallow habitats (2 – 5 m), juvenile abalone (< 45 mm) tend to prefer deeper water (6 – 9 m). Abalone have an affinity for coralline algae, larger but fewer
abalone were found in association with macro-benthic algae, and more abalone were found in association with red sea urchins but these abalone were significantly smaller in size. More abalone, particularly juveniles (<45 mm), were observed at night than during the day.
DFO researchers have been monitoring the movements of 2,000 abalone tagged and aggregated at high quality habitats to increase reproductive capability. While it’s a lot of work to track the tagged abalone, in 2002 at least 37% of the tagged abalone have been sticking around - 84 have been observed more than once - which indicates promise for the rebuilding program.
In May 2004, DFO researchers set out on the M/V Vector to continue the work with the Haida Gwaii Abalone Stewards and Kitasoo Abalone Stewardship Project completing condo surveys, transect surveys, tagging abalone and putting in new condos. The cruise continued on to index site surveys in Queen Charlotte & Johnstone Straits. They are also using their observations to refine a habitat model designed to assist in defining ‘critical habitat’ for abalone in BC.
Papers presented at the 2003 Workshop for Rebuilding Techniques for Abalone in BC are now published in the Journal of Shellfish Research (volume 22, number 3, December 2003, pp. 801-855).
Proceedings of the Workshop on Rebuilding Techniques for Abalone in BC are now published in the Canadian Technical Report of Fisheries and Aquatic Sciences 2482.
Red urchin fishermen have volunteered to collect observations of abalone that will aid in long-term population trends. To date, most reports have seen just a few (2-10) abalone. Abalone are also counted and measured for DFO during urchin surveys.
Surveys – population status
Surveys of key index sites have been conducted by DFO since 1978 to monitor abalone abundance and to evaluate recovery. The results from the most recent index sites surveys will be summarized in the Abalone Stock Status Report to be reviewed by the Pacific Scientific Advice and Review Committee (PSARC) in Nov 2004. The preliminary results show that the objectives of the abalone recovery strategy are not being met: --- Abalone continues to decline! More sites are without any abalone and the density of mature abalone has dropped further, below the level it was at in 1990 when all fishing was closed!
Although there were a few historic surveys in southern BC,
they did not afford the extended coverage provided in the index surveys. Therefore, indices of abundance are being
established in southern BC. So far,
index sites surveys have been initiated on the west coast Vancouver Is.,
New survey methodology is being developed to better detect changes in the population while abalone are at such low abundance. A ‘random stratified survey design’ is being developed to improve the statistical power of the surveys.
Habitat Stewardship Program
Four projects on abalone rebuilding are again underway thanks to $141,250 for 2004/5 from the federal government’s Habitat Stewardship Program for Species at Risk http://www.cws-scf.ec.gc.ca/hsp-pih/default_e.cfm. The projects involve coastal First Nations and coastal communities in outreach activities and community-driven programs.
Bamfield Huu-ay-aht Community Abalone Project
Haida Fisheries Program
Total: $255, 000
In May 2004, the Haida Gwaii Abalone Stewards revisited 40 ‘condos’ (structures to enhance and sample juvenile habitat), deployed 16 new condos, and resurveyed 8 treatment and control sites. They saw about 2 dozen tagged abalone and many shiny tiny (2-5 mm) newly settled abalone on the condos. Education / awareness activities included a booth at the Tlell Fall Fair on the August long weekend and the launch of the Marine Matters web site http://www.marinematters.org/ with WWF Canada.
Heiltsuk Abalone Stewardship Program
Years: 2005 *NEW*
The Heiltsuk Abalone Stewardship Project was initiated in 2004 after interest was raised at the Abalone Recovery Strategy workshop in 2002. The project aims to establish baseline abundance estimates in the area and will build on historic surveys from 1999-2001. The project kicked off their first community workshop Aug 23. Surveys are scheduled for Oct.
In May, the Kitasoo Abalone Stewardship Project managed to tag 1,000 abalone to track success of the rebuilding sites established in previous years. The abalone curriculum developed in 2002-2003, is now in operation in local class presentations, games, and educational exercises.
Despite the complete ban on harvest since 1990, there is still no sign of abalone recovery. Illegal harvest is still considered the most significant threat, reducing numbers and spreading mates too far apart for successful reproduction.
To stop the ongoing problem of illegal harvesting, abalone Coast Watch programs are being developed under the lead of the Bamfield Huu-ay-aht Community Abalone Project, Gwa’sala-‘Nakwaxda’xw Fisheries, Haida Gwaii Abalone Stewards, Kitasoo Abalone Stewardship Program and the Heiltsuk Abalone Stewardship Program. Co-operation and support in reporting illegal activities is also being provided by other concerned organizations, such as the Pacific Urchin Harvesters Association http://www.puha.org/.
Reports of abalone poaching receive high priority with Fisheries & Oceans Canada Conservation and Protection Officers. Directed funds mean abalone-related reports receive attention. Local Fishery Officers are also working with groups like the Haida Gwaii Abalone Stewards in developing local Coast Watch programs. Increased fines through the courts and seizure of gear are helping to create deterrents. Genetics studies are ongoing to identify illegal abalone in the marketplace.

Abalone Recovery Implementation Group
The May 28 meeting of the Abalone Recovery Team recommended that an ‘Abalone Recovery Implementation Group’ be formed to oversee implementation of the abalone recovery strategy / action plan.
