What Black Redhorse Are and Where They Live

Black redhorse are a bottom-feeding fish found across eastern North America, from the Great Lakes south through the Mississippi River system and into the Atlantic drainages. They are a member of the sucker family, built for life on the river or stream floor where they root through gravel and silt for food. Unlike their cousins the common redhorse, black redhorse have a darker overall coloration and smaller, more downturned mouths designed for feeding on invertebrates and algae rather than larger prey.

You will find them in moderate to fast current in rivers and larger streams, usually in water between 3 and 15 feet deep. They prefer rocky or gravelly bottoms where current keeps the substrate clean. In spring, they move into shallower water and smaller tributaries to spawn, which is when they become most catchable for anglers. Black redhorse are not migratory in the way that shad or salmon are, but they do shift their location seasonally based on water temperature and food availability.

The species is most abundant in the Ohio River drainage, the upper Mississippi, and throughout the Great Lakes tributaries. They are less common in coastal Atlantic rivers but present in many of them. Check your state's fish survey data or contact the local fisheries office to confirm they are in the specific water you plan to fish.

Key Takeaways

  • Black redhorse are bottom feeders that live in moderate to fast current over rocky or gravelly substrate in rivers and larger streams.
  • Spring spawning runs in shallow tributaries and tailwaters below dams offer the most consistent fishing opportunity.
  • Simple rigs with small live bait or prepared dough work better than artificial lures, since black redhorse feed by feel on the bottom.
  • Check your state's fishing regulations for any size or bag limits specific to redhorse, as rules vary by region.
  • Black redhorse are strong fighters for their size and provide good sport on light tackle, though they are not a primary target species in most areas.

Seasonal Patterns and Best Times to Fish

Spring is the prime season for black redhorse fishing, typically from late March through May depending on your latitude. As water temperatures rise above 50 degrees Fahrenheit, black redhorse move into shallow tributaries and the tailwaters below dams to spawn. These shallow runs concentrate fish in predictable locations, making them far easier to locate and catch than they are during the rest of the year. A single tributary mouth or dam tailwater can hold dozens of fish during the peak spawn.

Summer fishing is slower. Once spawning is complete and water temperatures climb into the 70s, black redhorse disperse into deeper pools and faster current. They are still present and catchable, but they are spread out and less aggressive. Early morning and evening sessions produce better results than midday fishing. Fall brings a second, shorter window of opportunity as water cools and fish move back into moderate current zones, though the bite is not as intense as spring.

Winter fishing is possible in southern portions of their range, but in northern areas black redhorse move into deep pools and become nearly inactive. Most anglers do not target them during winter months.

Tackle, Bait, and Rigging for Black Redhorse

Black redhorse are not selective about tackle, but they do require a presentation that reaches the bottom where they feed. A simple slip-sinker rig works well: thread your main line through a barrel swivel, tie on a 12- to 18-inch leader of 6- to 8-pound test, and attach a small hook (size 6 to 10). Pinch a split shot or two above the swivel to keep the rig on bottom in current. The sinker weight depends on current speed—use just enough to hold position without dragging.

Live bait is the most reliable choice. Small shiners, dace, or creek chubs in the 2- to 3-inch range work well. Hellgrammites and crayfish are also effective. If live bait is not available, prepared dough balls or commercial stink baits designed for catfish will catch black redhorse. Some anglers report success with small crawfish-pattern soft plastics fished on a light jig head, though this method is less common.

Rod and reel choice is straightforward: a 6- to 7-foot medium-light spinning rod with 8- to 12-pound braided or monofilament line handles black redhorse well. The lighter line helps you feel the subtle bottom contact and bites that are characteristic of bottom feeders. Braided line offers better sensitivity and bottom contact than monofilament, which is an advantage when fishing deep or in heavy current.

Where to Fish: Rivers, Streams, and Tailwaters

Tailwaters below dams are often the most productive spots, especially during spring. The current below a dam creates ideal habitat—moderate to fast flow, oxygenated water, and a clean gravel bottom where black redhorse congregate. The Ohio River and its major tributaries (the Wabash, Licking, and Kentucky rivers) are well-known black redhorse fisheries. The upper Mississippi and its tributaries, including the Wisconsin and Minnesota rivers, also hold good populations.

In the Great Lakes region, the Maumee River in Ohio and the Grand River in Michigan are reliable options. Smaller tributaries that feed larger rivers often concentrate spawning fish in spring. Look for areas where a small creek enters a larger river—these confluences funnel fish into a small area and make them easier to locate.

Access varies by location. Many tailwaters have public boat ramps and bank access. State wildlife areas and public fishing easements provide access to some tributary streams, though you will need to check local regulations and obtain permission where required. Contact your state's fish and wildlife agency for a list of public access points in your target area.

Regulations and Catch Limits

Black redhorse are not a regulated species in most states—meaning there are no special restrictions on size or bag limits. However, this varies by region. Some states include redhorse in general rough fish categories with no limit, while others have specific rules. A few states protect certain redhorse species or require a minimum size. Check your state's current fishing regulations before you fish, as rules change and vary between regions within the same state.

Many states publish their regulations online through the fish and wildlife agency website. Search for your state plus "fishing regulations" and look for the section on rough fish or non-game fish. If black redhorse are not mentioned by name, they are usually covered under a general sucker or rough fish category. When in doubt, contact the local fisheries office by phone—they can answer questions about specific species and locations in minutes.

What to Expect When You Hook One

Black redhorse are strong, determined fighters that will test your tackle and patience. They do not jump or make long runs like a smallmouth bass, but they pull hard and shake their heads in a way that can break light line if you are not careful. Set the hook firmly when you feel a bite—redhorse have tough mouths and a soft hook set often results in a missed fish.

Once hooked, black redhorse tend to dive toward the bottom and use current to their advantage. Keep your rod tip up and maintain steady pressure. They rarely make dramatic runs, but they will use their weight and the current to work against you. A 2- to 3-pound black redhorse on 8-pound line provides genuine sport and will take several minutes to land. Larger fish (4 to 6 pounds) are possible but less common.

Black redhorse are not typically kept for food, though they are edible. Most anglers practice catch-and-release. Handle them carefully when removing the hook, as their slime coating protects them from infection. Wet your hands before handling, and return them to the water quickly.

Frequently Asked Questions

Are black redhorse good to eat?

Black redhorse are edible and have been eaten historically, particularly in the South and Midwest. The meat is firm and white, though it can be bony. Most modern anglers practice catch-and-release because black redhorse are not a primary food fish and populations are stable without harvest pressure. Check your state's fish consumption advisories before keeping any fish from a river, as some waters have mercury or other contaminant warnings.

How do I tell a black redhorse apart from other redhorse species?

Black redhorse are darker overall than common redhorse, with a more uniformly dark gray or olive back and sides. Their mouth is smaller and more downturned than common redhorse. The easiest way to confirm the species is to count the pharyngeal teeth (throat teeth) or consult a regional fish identification guide. Your state's fish and wildlife agency website usually has a photo guide showing the differences between local redhorse species.

Can I catch black redhorse on artificial lures?

Black redhorse can be caught on small soft plastics and jigs, but they are not aggressive hunters and rarely chase lures. Live bait or prepared dough is far more effective because black redhorse feed by feel on the bottom, not by sight. If you want to use artificials, small crawfish-pattern plastics on a 1/16- to 1/8-ounce jig head fished slowly along the bottom will occasionally produce, but expect fewer bites than with live bait.

What is the difference between black redhorse and common redhorse?

Common redhorse are larger, lighter-colored, and have a more terminal (forward-facing) mouth. Black redhorse are smaller, darker, and have a more downturned mouth adapted for bottom feeding. Common redhorse are more aggressive feeders and will chase small fish, while black redhorse are primarily bottom grazers. Both species inhabit similar water, but black redhorse are usually found in faster current and over cleaner substrate.

Do I need a special license to fish for black redhorse?

No. A standard freshwater fishing license covers black redhorse in all states where they are found. Some states offer reduced-cost rough fish licenses that include redhorse, but a regular license is sufficient. Check your state's requirements for license type and any special stamps or endorsements needed for the water you plan to fish.
