Fish Species
Fishes Found in Fresh Waters of Pacific Northwest States and British Columbia
[Last updated October 6, 2023.]
This page shows the species of fishes present in fresh waters of the states and Canadian province of the Pacific Northwest. Several species are mainly marine but sometimes are found in fresh waters.
The tables below are listed alphabetically by Latin family name. Within each family, species and subspecies are arranged alphabetically by Latin name. For each species/subspecies we provide the common name(s) and indicate if it occurs in the states of Idaho (ID), Montana (MT), Oregon (OR), Washington (WA) and the province of British Columbia (BC) by citing the reference that provided that information. The list of references used is provided at the bottom of the page. The letters in the “State/Province where present” column indicate where the occurrence information came from. For example, a capital ‘A’ means the information is from Inland Fishes of Washington, Second edition, by Richard S. Wydoski, and Richard R. Whitney. Unless otherwise noted, Latin names are from Common and Scientific Names of Fishes from the United States, Canada, and Mexico, Eighth Edition from the American Fisheries Society and the American Society of Ichthyologists and Herpetologists (2023). Latin names from the Integrated Taxonomic Information System (as of July 2021) are also included where they do not agree with, or add to, the AFS/ASIH names. However we recommend using the Latin name from AFS/ASIH where the two conflict. Some Latin names are links you can follow to find information about the species in FishBase. Common names are capitalized to match the approach used by AFS/ASIH (2013), though that capitalization standard is not universally used.
