Information in Support of a Recovery Potential Assessment of Eulachon (Thaleichthys pacificus) in Canada
By C.A. Levesque and T.W. Therriault
Eulachon (Thaleichthys pacificus) are a culturally important, anadromous smelt species that has experienced significant population declines in British Columbia, Canada. The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) currently is reviewing the status of eulachon populations in Canada to assess their conservation status but due to the noted population declines, a listing under the Species at Risk Act (SARA) is possible. Should eulachon be assessed by COSEWIC as Threatened or Endangered, Fisheries & Oceans Canada (DFO) undertakes a number of actions required under SARA. In advance of potential listings for aquatic species, DFO’s standard practice is to conduct a recovery potential assessment (RPA) for the species to help inform the SARA listing process. Thus, this document provides background information on eulachon in Canada in support of a RPA.
