Proceedings of the Regional Peer Review of the Recovery Potential Assessment – Lake Sturgeon, Acipenser fulvescens, Designatable Units 1 (Western Hudson Bay Populations) and 2 (Saskatchewan-Nelson River Populations); March 12–13, 2019
Presidents : Tom Pratt and Chantelle Sawatzky
Editor : Chantelle Sawatzky
Summary
A regional science peer-review meeting was held on March 12–13, 2019 in Winnipeg, Manitoba. The purpose of the meeting was to assess the recovery potential of the Western Hudson Bay populations (Designatable Unit [DU] 1) and Saskatchewan-Nelson River populations (DU2) of Lake Sturgeon (Acipenser fulvescens), to provide advice that may be used for the listing decision, development of a recovery strategy and action plan, and to support decision making with regards to the issuance of permits and agreements. Participants included DFO Science, Species at Risk, and Policy programs, Alberta Environment and Parks, Manitoba Conservation and Water Stewardship, Manitoba Hydro, Ontario Ministry of Natural Resources and Forestry, Ontario Power Generation Inc., Saskatchewan Ministry of Environment, Saskatchewan Water Security Agency, SaskPower, academics, and environmental consultants.
The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated Lake Sturgeon in DUs 1 and 2 as Endangered in 2017. The distribution and abundance of mature individuals in DU1 have declined dramatically, largely as the result of harvesting, and habitat loss and alteration due to dams. Similarly, in DU2 harvesting and dams have caused historical declines and although some populations appear to be recovering, this species is not yet clearly secure.
This proceedings report summarizes the relevant discussions from the meeting and presents recommended revisions to be made to the associated research documents. The Proceedings, Science Advisory report, and Research Documents resulting from this science advisory meeting are published on the DFO Canadian Science Advisory Secretariat (CSAS) website.
