Catfish fishing has gotten a reputation for being simple — throw some stink bait on a hook, toss it in deep water, wait. And while that works sometimes, consistently catching big catfish takes more than patience and a strong nose. As someone who’s spent a lot of summer nights anchored over deep river holes waiting for the line to move, I’ve learned that understanding how catfish actually behave changes the whole game. Here’s what I know.
Understanding Catfish
Catfish are primarily nocturnal, most active at dawn, dusk, and through the night. They navigate and hunt almost entirely by smell and taste — their barbels (those whisker-like appendages on their face) are sensory organs loaded with taste receptors. That’s why strong-smelling bait works: catfish can detect scent from a remarkable distance downstream in murky water where visual hunting is limited.
Habitat
They’re adaptable — you’ll find catfish in rivers, lakes, ponds, and reservoirs across the country. During summer days, large catfish hold in deep, cool water. At night they move to shallower zones to feed actively. Seasonal patterns matter: spring catfish are in transitional water moving toward spawning areas, while fall fish are aggressively building reserves for winter. Knowing where the fish are at this moment, not just generally, is what separates a good catfishing session from a blank one.
Species
The three main species worth knowing: channel catfish are the most widely distributed and the most caught — cooperative biters on a range of baits. Blue catfish run the largest, with river giants regularly topping 50 and occasionally 100 pounds; cut shad is the preferred bait. Flathead catfish are the pickiest of the three, almost exclusively eating live prey — live bluegill or large shiners are far more effective than cut bait for flatheads.
Gear and Equipment
Rod and Reel
A medium-heavy to heavy rod in the 7 to 8-foot range gives you the backbone to handle a large catfish and the length for casting heavy rigs from the bank. Baitcasting reels give better control and line capacity for heavy setups, though a quality spinning reel works fine for most river catfishing. The drag needs to be reliable — big catfish make strong runs and a drag that seizes up loses fish.
Line
Heavy monofilament or braided line in the 20-50 lb test range is appropriate depending on the size of fish you’re targeting. I’m apparently more conservative about line weight than most people I fish with — I use 40 lb braid as my standard for river catfishing and it has never been the limiting factor on a fish I lost. Heavier line handles structure and current better and doesn’t fail when a big blue runs under a submerged log.
Hooks
Circle hooks are the standard for catfishing for good reason: they hook the fish in the corner of the mouth on the hookset, which is both more secure and causes less injury. Size 5/0 to 8/0 covers most situations. Treble hooks work well when you’re using soft stink baits that need a multi-hook platform to stay on, but they’re harder on fish you’re releasing.
Bait and Lures
Natural Bait
- Shad: A favorite for blue catfish. Cut shad is especially effective — fresh-cut or fresh-frozen is better than thawed bait that’s been sitting. The oily scent disperses quickly downstream.
- Nightcrawlers: Ideal for smaller channel catfish. The wriggling motion adds appeal.
- Chicken liver: Classic and effective for channel cats. It falls apart quickly on the hook, which is both its weakness (use a mesh bag or rubber band to keep it together) and its strength — it releases scent fast.
- Stink baits: Commercial dip baits and punch baits work well for channel catfish. The strong odor carries far in moving water and triggers feeding from a distance.
Artificial Bait
Artificial options are less common in catfishing but not useless. Scent-impregnated plastic baits in combination with stink bait rigs give you the durability of plastic with the scent draw of natural bait. Worth experimenting with when live bait isn’t available.
Techniques for Catching Catfish
Still Fishing
The simplest approach: cast to a promising spot, set the rod in a rod holder, keep enough tension to feel a strike. In rivers, use enough weight to hold bottom against the current without being so heavy that the fish feels resistance and drops the bait. Slip sinker rigs — where the line runs through the sinker — work well because they let the fish take line without immediately feeling weight.
Drift Fishing
Best for covering water in large rivers and reservoirs. Let the boat drift with the current while dragging baited rigs at the bottom. Run multiple rods and stagger your depths to cover different parts of the water column. When you get a bite, mark the spot and work that area thoroughly before moving on.
Jug Fishing
A fun and legitimate technique — set out a line of jugs or foam floats with baited hooks attached at various depths, let them drift across a flat or pool, and watch for the ones that get pulled under. It’s effective, it covers water, and there’s something oddly satisfying about watching a jug get yanked sideways by a fish you haven’t seen yet.
Trotlines
A long horizontal line anchored at both ends with multiple baited hooks along its length — effective for catching volume in rivers and lakes where regulations permit. Check your local regulations first; trotlines are restricted or banned in some states. Check them frequently (at least every few hours) and rebait as needed.
Location and Timing
Best Fishing Spots
- River bends: Catfish gather in deeper water on the outside of bends where currents slow and deposit food.
- Below dams: Turbulent tailwaters attract catfish searching for disoriented baitfish and other food flushed through.
- Lake coves: Sheltered areas with consistent food supply attract catfish during evening and nighttime feeding periods.
- Log jams: Structure provides cover and a steady food source. Flatheads in particular love holding in heavy wood.
Optimal Fishing Times
Early morning and late evening are prime windows, with nighttime being the best overall for big catfish. I’ve consistently caught my largest fish between 9 PM and 2 AM on summer nights. During the day, target deeper water and slow your presentation — catfish are still there, just less actively feeding.
Handling and Releasing Catfish
Handling Catfish
This is the part new catfish anglers learn the hard way: the spines on the pectoral and dorsal fins are sharp and can puncture skin with a lot of force when the fish thrashes. Grip a smaller catfish by placing your thumb in the mouth, fingers under the jaw, with the dorsal spine between your index and middle fingers. For large fish, grip behind both pectoral fins with a towel or use a lip gripper. Don’t squeeze — catfish can “lock” their pectoral spines and it takes some maneuvering to release them if they do.
Proper Release
Minimize handling time, keep the fish in the water as much as possible, and support it horizontally until it can swim under its own power. A large catfish that’s been fighting hard needs a moment to recover before you let it go — don’t just drop it back in the water.
Catfishing in Different Seasons
Spring
Catfish move from deep to shallow as water temps rise above 50°F. They’re feeding actively and moving toward spawning areas near tributary creeks and cut banks. Cut bait fished near those transitions is productive.
Summer
Deep during the day, shallow at night. This is when night fishing earns its reputation. Use stink bait or cut shad for channel and blue cats; live bait for flatheads near heavy structure.
Fall
Aggressive pre-winter feeding period. Catfish return to shallower zones and feed heavily. Experiment with depths and baits — they’re less selective in fall than in any other season.
Winter
Slow down your presentation drastically. Fish the deepest holes in the river system, where water temperatures are most stable. Live or cut bait fished right on the bottom, barely moving, is what triggers sluggish winter catfish to bite.
Advanced Tips
Sonar and Fish Finders
A fish finder changes river catfishing significantly. You can locate the deep holes, identify suspended fish, and mark productive spots with GPS for repeat visits. Entry-level units are affordable and well worth the investment if you fish for catfish regularly.
Chumming
Legal in many states for catfish: throw bait scraps, soured grain, or commercial chum into the water upriver from where you’re fishing. The scent draws catfish into your zone. Check local regulations before doing this — it’s restricted in some areas.
Water Temperature
Catfish are cold-blooded and their metabolism adjusts to water temperature. Below 50°F they’re barely feeding. Between 65-80°F they’re most active. Above 85°F in shallow water they get stressed and retreat to depth. A thermometer isn’t overkill — it tells you where to fish and how aggressive to expect the fish to be before you’ve made a single cast.
Conservation
Follow size and bag limits. Large catfish — especially big blue and flathead fish — are old, slow-growing animals. A 50-pound blue catfish might be 20 years old. Release the big ones. Harvest smaller fish in the 3-8 pound range if you want table fare, and let the large fish continue to grow and reproduce. The health of your local catfish fishery depends on enough anglers making that choice.
