COSEWIC Assessment Summary and Status Report: Coastrange Sculpin - Cultus Population, Cottus aleuticus

Assessment Summary – April 2010

Common name
Coastrange Sculpin - Cultus Population

Scientific name
Cottus aleuticus

Status
Threatened

Reason for designation
This species is a small Canadian endemic freshwater fish found in a single lake in the lower mainland region of southwestern British Columbia, an area undergoing sustained and rapid urbanization. The lake is heavily used by recreationists and drains into the lower Fraser River area where many invasive species are well-established. Trends in indices of abundance suggest a persistent decline and the single location makes the species particularly vulnerable should either habitat quality decline or vertebrate invasive species become established in the lake.

Occurrence
British Columbia

Status history
Designated Special Concern in April 1997. Status re-examined and designated Threatened in November 2000 and in April 2010.
