White Sucker
Catostomus commersonii
White Sucker (Catostomus commersonii) is a widespread North American sucker found in cool to warm freshwater streams, rivers, and lakes. It feeds by sucking up bottom invertebrates and detritus, and is often overlooked by anglers but can be caught readily on natural baits.

Identification points
- Single dorsal fin with a long, smoothly curved back behind it
- Thick, downturned sucker mouth with fleshy lips and no obvious teeth
- Large cycloid scales and a silvery body that often shows darker back and dusky fins
Habitat
Bottom-oriented in clear to stained freshwater streams, small rivers, lake margins, and backwaters with sand, gravel, mud, or mixed substrates; often near current breaks, pools, riffle tails, and shallow feeding flats.
Bait notes
Best on worms, nightcrawlers, salted minnows, insect larvae, dough balls, corn, and small pieces of salmon egg or cheese. Small hooks and light bait scent can help; they are not a premier game fish but bite well on simple natural baits.
Behavior
Feeds mostly on benthic insect larvae, worms, small crustaceans, algae, and organic detritus by rooting along the bottom. Spawns in spring over gravel in tributaries and runs; often schools by size and can be active in cool water.
Caution
none notable
Fishing notes
Fish near bottom with a small split shot, drift bait through current seams, or set still baits in pools and along shore margins. Light tackle improves bite detection; hooksets should be gentle because of their soft, fleshy mouths.
