Freshwater · Spring best; April to June in riffles, present in rocky streams year-round
Northern Hog Sucker
Hypentelium nigricans
A distinctive riffle sucker with a bony, ridged head and dark saddles, famous for pushing rocks over with its fleshy snout to uncover insect larvae. A clean-water indicator of Ozark and Appalachian streams, it is mostly an encounter and identification fish that also takes a small worm drifted through the riffles it feeds in.

Identifying features
- Bony head with a clear depression between the eyes and ridged, rectangular skull
- Four to five dark saddles across a mottled brown back

Habits
- Pushes and rolls rocks aside with its snout to expose insect larvae and snails
- Feeds head-down in riffles, often in small loose groups
- Spawns in spring over gravel in riffles, males developing tubercles
- Needs clean, rocky, well-oxygenated water — a stream-health indicator
- Often seen by snorkellers holding station in the current between rocks

Where they live
How to catch them
Small worms through riffles and rocky runs River
Rig: Light rod, split shot and a small size 8 hook with a worm piece, drifted or held through riffles and rocky runs
Bait/lure: Small worms
Key tip: Keep the bait tumbling right along the rocks where fish are rooting — most bites come in the fastest water.
Bottom fishing below riffles River
Rig: Small sinker rig with a worm in the pool tail just below a riffle in clear streams
Bait/lure: Worms, crayfish pieces
Key tip: Fish early and late when hog suckers drop into the pool to rest and feed; approach quietly in clear water.

Recommended gear for this species
Rod · Best value
8' medium-heavy catfish rod
≈ US$80-130
Long enough to lob heavy bait rigs, strong enough to move a flathead off the bottom.
Reel · Budget
Baitcasting or 4000-6000 spinning reel
≈ US$60-100
Line capacity and drag for long runs — catfish and carp both make them.
Terminal · Budget
Circle hooks, sliding sinkers and cut-bait rigs
≈ US$15-25
A slip-sinker rig with a circle hook is the proven bottom setup for cats and carp alike.
