Creek Chub
Semotilus atromaculatus
Creek Chub is a common North American minnow found in small streams, headwaters, and clear warmwater creeks. It is a hardy, schooling baitfish and micro-predator that readily takes small baits and lures.

Identification points
- Distinct black blotch at the front base of the dorsal fin
- Dark stripe running from snout through eye to tail
- Large males develop a swollen, dark head and build pebble nests
Habitat
Shallow to moderately deep riffles, pools, and undercut banks in clear creeks, small rivers, and spring-fed headwaters; often around woody debris, boulders, and gravel over sand. It tolerates warm water and lower oxygen better than many minnows.
Bait notes
Tiny pieces of worm, maggots, insects, dough bait, and bread balls work well. Small spinners, micro-jigs, and bead-head flies can also catch them when they are actively feeding.
Behavior
Forms loose schools and feeds on aquatic insects, small crustaceans, algae, and occasionally fish eggs or fry. Spawning males build distinctive pebble nests in shallow gravel runs; they are active in daylight and can be wary in clear water.
Caution
None notable; Creek Chub is a small, non-venomous freshwater minnow, but follow local regulations on bait collection and use.
Fishing notes
Use ultra-light tackle and small hooks or tiny lures fished upstream with a natural drift near cover and gravel runs. They are often easiest to catch with light float rigs or by sight-fishing in calm water; many anglers target them as live bait rather than a table fish.
