The largescale sucker is native to the Pacific Northwest, occurring from British Columbia south to Oregon.

They are an important part of the food web and the diet of fish-eating animals (such as osprey, eagles, river otters, and other fish).

Ignorance about suckers is widespread and many anglers in the Pacific Northwest kill them because they mistakenly believe them to have a negative impact on salmon and trout stocks.
