If you want to catch more catfish — and who doesn’t? — it’s important to realize that catfishing isn’t complicated, but you shouldn’t oversimplify it either.

A cast from anywhere on the bank might produce a hook-up. But savvy anglers know successful fishing usually results from studying catfish behavior and learning to put the right bait in the right place at the right time. That goes for eating-size channel cats for the next fish fry or trophy-class blues and flatheads that test tackle and determination.

All Catfish Are Not Equal

A catfish is a catfish is a catfish, right? This is another way of saying all catfish are alike and tactics that work for one species work for all. Many anglers fish as if this were so, but it is not.

Each catfish species exhibits behaviors specific to that species. Consequently, we must gear our tactics toward the particular species we hope to catch in order to enjoy success.

For example, trophy blue cats behave much like striped bass. They feed primarily on shad, herring and other schooling, highly mobile baitfish. Consequently, big blues are more migratory than other cats and more frequently found in open-water habitat.

While big blues and channel cats often congregate in loose schools containing several trophy-class individuals, flatheads are more solitary. Rarely will you catch more than one trophy flathead in a single fishing hole. Flatheads are cover-lovers as well, hiding in brush, log piles and cavities to ambush prey. Channel cats and blues sometimes do this, too, but not as frequently as their big brown cousins. Flatheads almost always are caught in or near some type of dense cover, while blues and channel cats most often are not.

These are just two examples showing species behavior differences. Yet knowing just these things, we can immediately improve our odds for success because we know we must target the predominant species of catfish in each body of water using tactics specific to that species. To do this, we must learn the specific behavior patterns exhibited by big blue, channel and flathead catfish. Failure to do so will lead to frustration because trophy cats will be caught by chance and not by design. And when we leave things up to chance, the odds for success rarely fall in our favor.

Big Waters Produce Big Cats

If you would like to catch a mess of small catfish (5 pounds or less) for the dinner table, you can fish almost anywhere catfish swim — from your neighbor’s farm pond to your state’s biggest lakes and rivers. If your goal is catching some true heavyweights, focus your fishing efforts strictly on large rivers and lakes. Trophy cats seldom come from creeks, ponds and small lakes. It happens occasionally, but not often. When seeking a big pole bender, zero in on sizeable bodies of water.

Each river and lake also has specific areas where you should focus your attention. The best waters usually are those where catfish aren’t heavily pressured by commercial fishing or excessive recreational fishing. Waters where minimum length restrictions are imposed, and where catch-and-release fishing is mandated, also produce more than their share of jumbo whiskerfish.

Catfish are well-adapted for feeding on the bottom of rivers, lakes and ponds, but if you think they never feed at mid-depths or on the surface, you’re wrong. Trophy blue and channel cats often suspend at mid-depths to prey on baitfish such as shad and herring. And at times — when frogs are plentiful, for example — big cats will come to the surface to gobble up their dinner. Working a live frog topside is one of the best of all ways to catch a channel cat weighing more than 20 pounds.

If bottom-fishing doesn’t produce a bite within a reasonable time, watch for surface activity (particularly in summer and near dawn or dusk) that indicates fish are taking their food topside, or watch your sonar for suspended fish and use a float rig to present bait at the proper level.

Timing & Tips

Catfishing once was considered strictly a nighttime sport. We know now, however, that cats big and small can be caught day or night using the right tactics. In ultra-clear waters, night-fishing often is best, but in the colored waters typical of the best catfish rivers and lakes, whiskerfish are landed as often at high noon as they are at midnight. Take your pick.

Also bear in mind some seasonal considerations. Trophy channel and blue cats are caught every month of the year, and in some areas, fishing during winter’s cold is considered best because it is then that trophy fish gather in larger concentrations in deep wintering holes. Both species, however, fall prey to good fishing tactics year ’round.

Flatheads become lethargic in cold water, and though they can sometimes be coaxed to bite in winter, the best fishing tends to be during high-water periods in spring, and again in late fall when big flatheads feed ravenously before a season of inactivity. Summer fishing can be excellent as well.

Many cat fans don’t have problems finding fish each season, yet they’re continually frustrated when they can’t hook those that bite. To cure this problem, always fish with sharp, exposed hooks. Run the hook point over a fingernail. Sharp hooks dig in. Those that skate across the nail without catching should be honed or replaced. And, instead of burying your hook in bait, leave the barb exposed. Catfish won’t notice. More hookups will result.

It’s also important to learn a variety of rigs, and use each when appropriate. A simple egg-sinker rig may work great in a pond but not a river. Drift rigs may be needed when cats are scattered and hard to find. A specialty rig, like the float-paternoster, is best when fishing large live baits. (Go to to see how to rig for catfish.) Learn more rigs, catch more cats.

Sometimes you have to fish a bait that allows you to cover a lot of water efficiently. When you're on the search for bass that have moved into deeper water off the bank and away from obvious holding spots, a swimbait can locate them.

On the Search with Swimbaits

One of the best imitations of a wounded baitfish is the soft-plastic jerkbait, or fluke. A fluke darting just beneath the surface can be too much for a bass to resist. Rig it and fish it according to water conditions and cover to make this great bait even more effective.
