Northern Hogsucker

Northern Hogsucker

The Northern Hogsucker is a distinctive freshwater sucker native to Wisconsin waters, particularly abundant in streams and rivers throughout the state.

Wisconsin populations are stable and considered common, with the species serving as an excellent indicator of stream health - their presence indicates clean, well-oxygenated water as they're intolerant of turbidity, siltation, and pollution.

Scientific Name: Hypentelium nigricans

Physical Characteristics:
  • This species is characterized by its almost box-shaped head, large lips covered with small bumps, and a distinctive black line around the lips not found in any other species.
  • They have large, speckled scales with a golden brown coloration and saddle-shaped dark patches along the upper body that provide excellent camouflage.
  • Northern hogsuckers in Wisconsin typically range from 8-10 inches and under a pound, though they can reach up to 14.5 inches and 2 pounds.

What to know

Habitat Distribution

  • They inhabit clear, fast-flowing streams and rivers with gravel or cobble substrates, particularly favoring riffle areas.
  • In Wisconsin, they're commonly associated with smallmouth bass habitat and can be found in both warm water creeks and the upper reaches of some trout streams.

Key Locations

  • Wisconsin's Bark River and Eau Claire River have produced good hogsucker fishing.

Specific Spots

  • Target rocky riffles, runs, and pools of clear creeks and small rivers with gravel/cobble bottoms.
  • The species favoring areas with fast-moving water over gravel substrates where they use their flattened bodies and large pectoral fins to navigate strong currents.
