Proceedings of the Regional Peer Review on the Updated Recovery Potential Assessment for Northern Madtom (Noturus stigmosus), 2012–2022; November 29-30, 2022
Chairpersons: Roanne Collins and Karine Robert
Editors: Lianna Lopez and Robin Gáspárdy
Summary
A regional Canadian Science Advisory Secretariat (CSAS) peer-review meeting was held on November 29–30, 2022 via the online platform Microsoft Teams. The purpose of this meeting was to assess the recovery potential of Northern Madtom (Noturus stigmosus) in Canada with updated information from 2012–2021, to provide advice that may be used for updating the recovery strategy and action plan, and to support decision making with regards to the issuance of permits and agreements under the Species at Risk Act (SARA). A Recovery Potential Assessment (RPA) was previously conducted for this species on March 19, 2012 (DFO 2012), so the focus of the peer-review was on new information and methods since then. Participants included Fisheries and Oceans Canada (DFO), Ontario Ministry of Natural Resources and Forestry (OMNRF), Environment and Climate Change Canada (ECCC), Michigan Department of Natural Resources (MDNR), Ontario Conservation Authorities, U.S. Fish and Wildlife Service (USFWS), U.S. Geological Survey (USGS), and academic experts.
Northern Madtom was assessed as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in November 2002 and again in May 2012 (COSEWIC 2012). The reason given for this designation was that it is one of the rarest freshwater fish in Ontario, being found at only four locations in river systems in southwestern Ontario, and faces substantial and ongoing threats including: siltation, turbidity, exotic species and toxic compounds. Northern Madtom was listed as Endangered under SARA in January 2005.
This proceedings document summarizes the relevant discussions from the peer-review meeting and presents revisions to be made to the associated draft Research Documents. The Proceedings, Science Advisory Report and the supporting Research Documents resulting from this science advisory meeting will be published on the DFO CSAS website.
