Shortjaw cisco are classified as At Risk in the current General Status of Alberta Wild Species report. See:
This species is also classified as Threatened under Alberta’s Wildlife Act. Protective regulations under the act
have yet to be placed outside of current Alberta sportfishing regulations. See:
In Alberta, the population appears stable and is not under any immediate threat of extinction. However, the distribution
of shortjaw cisco is naturally limited, isolated to one lake in the province, making the Alberta population especially vulnerable
to any threats.
Current threats to the Alberta population include potential competition and interbreeding with the closely related and abundant
Other ongoing research by the Royal Alberta Museum and Fisheries and Oceans Canada is focused on identifying whether other
populations of shortjaw cisco exist in lakes other than Barrow Lake in Alberta.
Alberta's sportfishing regulations have been modified to reflect the recommendations made in the recovery plan for this
species. A zero bag limit is enforced on cisco and whitefish in Barrow’s Lake, and no domestic fishing licences are issued
for the lake.
Common cisco (lake herring)
Shortjaw cisco and common cisco are very difficult to tell apart. The most widely accepted way to tell these species apart
is by counting gillrakers. The shortjaw cisco generally has fewer gillrakers.
