Freshwater · Spring to fall best; April to October in clear rocky streams
River Chub
Nocomis micropogon
A large, stout minnow of clear Appalachian and Great Lakes tributary streams, and a keystone of the riffle community: in spring males carry pebbles one by one to build nest mounds that many other fish species use for spawning. Breeding males develop horny tubercles on the head. Anglers catch river chubs on tiny baits — and value them honestly as premium live bait for smallmouth bass where bait rules allow.

Identifying features
- Stout, large-scaled minnow body, the biggest of the local chubs
- Large, slightly downturned mouth with a tiny barbel at each corner in adults
- Breeding males grow horny tubercles (bumps) on the head in spring
- Dark spot at the base of the dorsal fin in many fish
- Olive back, silvery sides; breeding males flush pink-purple
Habits
- Males build pebble nest mounds in spring that other species spawn over
- Feeds on insect larvae, crayfish, snails and algae grazed from rocks
- Holds in riffles and runs, moving to pools in winter
- Strong fighter for its size on light tackle
- Needs clean, well-oxygenated water; declines with heavy siltation
Distribution
Where to find them
- Appalachian clear rocky creeks and small rivers
- Tennessee and Kentucky upland riffle streams
- Lower Great Lakes and Carolina tributary riffles
Where they live
How to catch them
Tiny hooks with worms or dough in rocky streams River
Rig: Light rod, small float or split shot and size 10-14 hook with a worm piece, fished in riffles and runs
Bait/lure: Worm pieces, dough and corn
Key tip: Let the bait drift naturally along the bottom of a riffle — chubs pick it up on the move. Note: live river chubs are premium smallmouth bait where regulations allow baitfish use.
Micro jigs and small flies in riffles River
Rig: Ultralight spinning rod or light fly rod, micro jig or small nymph worked through riffles and pool tails
Bait/lure: Micro jigs and bead-head nymphs
Key tip: Keep offerings small and near the rocks; in spring, fish below active pebble mounds without disturbing them.
