COSEWIC
Assessment Summary

Assessment Summary – April 2007

Common name:
Blackfin Cisco

Scientific name:
Coregonus Nigripinnis

Status:
Data Deficient

Reason for designation:
Uncertainty about whether or not we are dealing with ecomorphotypes of a common and widespread species (C. artedii) or distinct populations of blackfin cisco (C. nigripinnis) cannot be resolved with the information currently available. Given that uncertainty, COSEWIC cannot unambiguously define what unit it would be assessing. However, COSEWIC notes that whatever the systematic status, there are distinct coregonids in these lakes that warrant enhanced conservation and protection. The uncertainty of systematic status can probably only be resolved through a comprehensive taxonomic/systematic review of the sub-genus.

Occurrence:
Ontario

Status history:
Designated Threatened in April 1988. Species considered in April 2007 and placed in the Data Deficient category. Last assessment based on an update status report.
