Fish

Thirty native freshwater fish species are present in Newfoundland and Labrador’s waterways, plus two exotic species. Eighteen species are found in Newfoundland and 26 in Labrador.
  • A new species, Log Perch, was found in southwestern Labrador (Grant 2001). Biologists believe there is much potential to find new species in areas yet not surveyed in southeastern and northern Labrador.
  • Banded Killifish is the only freshwater species assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), being listed as a Species of Special Concern.
