Catfish will eat almost anything, but they hunt by smell and taste, not sight
Catfish are bottom feeders with poor eyesight and a keen sense of smell. They navigate murky water and darkness using their barbels — the whisker-like sensory organs around their mouth — to taste the water and find food. This means your bait choice and presentation matter far more than the color of your lure or the clarity of the water. A catfish will find a smelly bait in complete darkness or heavy silt; it will ignore a flashy lure in clear water if there is no scent trail leading to it.
Understanding this behavior changes how you fish. You are not trying to trigger a strike through visual appeal. You are creating a scent plume that drifts downstream or across the current, and you are waiting for the catfish to follow that plume to your hook. This is why catfish fishing rewards patience and the right bait over casting skill or precise presentation.
Key Takeaways
- Catfish hunt by smell and taste using their barbels, so pungent, oily baits like chicken liver, cut shad, and stink baits outperform anything visual.
- Fish the bottom in deeper holes, channel ledges, and current breaks where catfish rest during the day, especially in warm months.
- Use a three-way rig or simple slip sinker to keep bait on the bottom without snagging, and check your line every 15 to 20 minutes for bites.
- Catfish bite year-round, but spring and fall offer the most active feeding; summer catfish move to deeper, cooler water during the day.
- Circle hooks set themselves as the catfish swims away, so you can wait for steady tension before reeling instead of setting the hook hard.
The baits that work best for catfish
Chicken liver is the standard catfish bait across the South and Midwest. It is inexpensive, stays on the hook reasonably well, and produces a strong scent that travels in current. You can buy it fresh at most bait shops, or save chicken livers when you butcher birds at home. Mold it onto your hook in a ball so it does not wash off immediately, but expect to replace it every 10 to 15 minutes as it breaks apart.
Cut shad and herring work especially well for larger catfish. A fresh shad cut into chunks releases more scent than chicken liver and attracts bigger fish. If you have access to fresh shad from your own catch or a bait shop, cut it into 2- to 3-inch pieces and fish it on a circle hook. The oily flesh creates a strong scent trail that carries far downstream.
Stink baits — commercial pastes and doughs designed to smell like decomposing matter — appeal to catfish's preference for aged, pungent food. These come in jars or tubes and stick to your hook without much effort. They work well in still water or slow current where the scent can build up around your bait. Some anglers make their own by fermenting chicken guts or shrimp in a jar for a few days.
Live baitfish like bluegill and shiners work for catfish, but they are less reliable than dead bait because catfish do not rely on sight to hunt. Dead bait produces more scent and is easier to keep on the hook during a long soak.
Where to find catfish in rivers and lakes
Catfish spend daylight hours in deeper water and move to shallower feeding areas at dusk and through the night. In a river, look for the deepest holes — places where the current has scoured a basin in the riverbed. These holes often sit just downstream of a bend or below a riffle. Fish the outside edge of the hole where the current slows and catfish rest without fighting the flow.
Channel ledges and drop-offs are prime spots. These are the steep banks where shallow water suddenly becomes deep. Catfish use these transitions as highways between feeding and resting areas. Cast your bait to the shallow side of the ledge and let it roll down into the deeper water.
In lakes, fish the deepest basin you can find, especially near a creek channel or old riverbed if the lake was formed by damming a river. Catfish congregate in these deeper zones during the day. At night, they move into shallower bays and along shorelines to feed. If you are fishing at night, move to 4 to 8 feet of water near the bank.
Current breaks — places where the current slows behind a rock, fallen tree, or bridge piling — concentrate catfish because they can rest without expending energy. Position your bait just upstream of the break so the current carries scent to the waiting fish.
Rigs and tackle that keep your bait on the bottom
A three-way rig is the most popular setup for catfish. Tie a three-way swivel to your main line, then attach a 12- to 18-inch leader with a sinker to one eye and a 24- to 36-inch leader with your hook to another. The sinker hangs below the swivel and keeps your bait near the bottom, while the hook leader extends to the side. This setup prevents the sinker from snagging on rocks and logs because the sinker can break free if it gets stuck while your line and hook remain intact.
A slip sinker rig is simpler and works well in open water. Thread a sinker onto your main line, tie a small swivel below it, then tie your leader and hook to the swivel. The sinker slides freely on your line, so when a catfish takes the bait and swims away, it feels no weight and does not drop the bait. This rig is easier to cast and less likely to tangle than a three-way.
Use a circle hook in size 2/0 to 8/0 depending on the catfish species and bait size. Circle hooks have a curved shank that catches in the corner of the mouth as the fish swims away. You do not need to set the hook hard — in fact, a hard set can break your line. Simply reel when you feel steady tension, and the hook will set itself.
Rod and reel choice is flexible. A medium-heavy spinning rod or baitcasting rod works fine. Catfish do not require sensitive equipment; they are not subtle biters. Use 15- to 20-pound monofilament or braided line if you are fishing snaggy areas where you might lose the sinker.
How to fish and what to expect when a catfish bites
Cast your rig out and let the sinker settle to the bottom. Reel up just enough slack so your line is slightly tight but not under tension. Set your rod in a holder and wait. Check your line every 15 to 20 minutes by gently reeling a few turns to feel whether a catfish has picked up your bait. If the line feels heavy or you sense movement, stop reeling and let the catfish take line.
A catfish bite feels like steady pressure rather than a sharp strike. The fish picks up the bait, tastes it with its barbels, and swims away. You will feel the line tighten gradually. Do not jerk the rod. Instead, reel steadily as the line becomes taut. The circle hook will set itself in the corner of the mouth. Catfish have tough mouths, so once the hook is set, you can reel with confidence.
Catfish fight by pulling hard and shaking their heads rather than running long distances. Keep your rod tip up and reel steadily. They rarely jump. Bring the fish to the net or shore by maintaining steady pressure; do not pump the rod unless you are fighting a very large fish.
If you do not feel a bite after 20 minutes, reel in and check your bait. If it has washed away or been nibbled by smaller fish, replace it. Catfish are not always aggressive; sometimes they mouth the bait without committing. Patience and fresh bait are your best tools.
Seasonal timing and water temperature
Catfish bite year-round, but their activity follows water temperature. In spring, as water warms above 60 degrees Fahrenheit, catfish move from deep winter holes into shallower feeding areas and bite aggressively. This is one of the best times to fish for catfish because they are hungry and active.
Summer catfish retreat to the deepest, coolest water during the day. If you fish during daylight in July and August, focus on the deepest holes and channel ledges. Night fishing is more productive in summer because catfish move into shallower water to feed after dark. Fish from dusk until an hour or two after midnight for the most consistent action.
Fall brings another active period as water cools and catfish feed heavily in preparation for winter. Water temperatures in the 60s and 70s trigger aggressive feeding, and catfish are less depth-dependent than in summer. You can catch them in moderate depths throughout the day.
Winter catfish are sluggish and concentrated in the deepest holes. They bite, but less frequently and less aggressively. Fish slowly and deliberately, and be patient with long waits between bites.
Handling catfish safely and preparing them to eat
Catfish have sharp spines on their pectoral and dorsal fins. These spines are not venomous, but they are sharp and can puncture skin and cause infection if not treated. Wet your hands before handling a catfish to reduce the chance of the fish thrashing and driving a spine into your hand. Grip the fish firmly behind the head, keeping your fingers away from the spines.
To remove the hook, use a pair of needle-nose pliers or a hook remover. Grasp the hook shank close to the mouth and back it out gently. If the hook is deep in the throat, cut the line and leave the hook rather than damage the fish's internal organs.
Catfish are excellent eating. Their flesh is mild, firm, and versatile. To prepare a catfish for cooking, place it on a cutting board and make a shallow cut around the base of the head, just behind the gill plates. Grip the head with a towel and peel the skin downward toward the tail. The skin comes off in one piece if you pull steadily. Once skinned, gut the fish by cutting from the vent to the throat and removing the organs. Rinse the cavity with clean water. The catfish is now ready to fillet, pan-fry whole, or prepare however you prefer.
Frequently Asked Questions
Do I need to fish at night to catch catfish?
No, but night fishing is more productive, especially in summer. Catfish are active feeders at night and move into shallower water. During the day, particularly in warm months, you will catch more fish if you fish deep holes and channel ledges. Spring and fall catfish bite well during daylight.
What size catfish can I expect to catch?
That depends on the water you are fishing. Small catfish (1 to 3 pounds) are common in most rivers and lakes. Larger catfish (10 to 30 pounds) are possible in bigger rivers and reservoirs, but they are less common and require patience. Channel catfish typically run 2 to 5 pounds; flathead catfish grow larger and are more aggressive hunters.
Can I use live baitfish instead of dead bait?
Yes, live baitfish work for catfish, but they are less reliable than dead bait or chicken liver because catfish hunt primarily by smell. Dead bait produces more scent and is easier to keep on the hook during a long soak. Live bait is more useful if you want to target larger catfish that hunt by sight as well as smell.
What should I do if my sinker gets stuck on the bottom?
If you are using a three-way rig, the sinker should break free under steady pressure, leaving your line and hook intact. If you are using a slip sinker rig, pull steadily on your rod until the sinker breaks free or your line breaks at the sinker. This is why heavier line is useful in snaggy areas. If the sinker does not break free, reel in and retie.
How do I know if a catfish has taken my bait versus a smaller fish?
Catfish produce steady, deliberate pressure on the line as they swim away with the bait. Smaller fish like bluegill or shiners produce quick tugs or nibbles. If you feel constant weight building on your line, you likely have a catfish. Reel steadily and the circle hook will set itself.
