North America is home to well over 30 catfish species. Many of the catfish species in North America are in isolated areas or small populations. Anglers call the most popular catfish species The Big Three. The Big Three include blue catfish, flathead catfish, and channel catfish.

The Big Three are the catfish species most anglers go looking for when they’re fishing. There are decent sized populations of other fish around North America as well, though. Whatever catfish species is the one you’re in the market for, it’s good to know how to tell them apart.

The types of catfish you want to catch affect many things. Obviously, the bait you’ll use is a factor. And of course, where you go fishing. When you fish will also be a factor. Some catfish are best caught at night. Some stick to deep water. Some are more difficult to catch at certain times of the year.

Knowing the difference between types of catfish is important. Knowing what catfish like to eat is integral to catching them. You need to know that some catfish species are not great for eating. Some are but only in the right conditions. Familiarize yourself with the different types of catfish and good luck.

Blue Catfish or Ictalurus Furcatus

Blue catfish are the largest species of catfish in America. Anytime you see someone posing with a giant trophy cat, this is likely what they have. Some blue catfish can reach weights of 100 pounds to 150 pounds. The official record for the largest blue catfish ever caught is 143 lb. That catfish was caught in John Kerr Reservoir in North Carolina. Don’t go out expecting a monster catfish, though. Your average blue is maybe 40 pounds.

Unofficial stories of much bigger blue catfish exist. Some claim to have seen a blue catfish that weighed 300 pounds or more. While it’s possible such fish may exist, there’s no definitive proof. Even a blue that weighs 100 pounds will be rare.

Appearance

Blue catfish are very long fish. They can reach lengths of 60 inches or more. The belly of a blue catfish will be silvery-white. The rest is a grey or slate blue color, hence the name. They have a moderate but not deeply forked tail and flat dorsal fins. There are four pairs of prominent whiskers around their mouths as well.

Habitat

Blue catfish are often found in freshwater rivers in channels. They do well in deep water. They also enjoy swiftly moving water. They can adapt well to new habitats. In fact, they are invasive in parts of Virginia. Anglers introduced them to Virginia in the 1970s. Now they are one of the dominant catfish species in the area.

You can find blue catfish in the Missouri, Mississippi, and Ohio rivers. They’re also well-stocked across 20 states. Arguably, the most desirable American catfish is the blue.

Fishing

Fresh shad is an ideal bait for catching blue catfish. Science classifies blue catfish as opportunistic bottom-feeders. That means they eat almost anything. Their normal diet consists of anything from crabs to clams to vegetation.

Flathead Catfish or Pylodictis Olivaris

Flathead catfish are one of the most common species of cats in America. They range from Canada down to Mexico. Some people will call them Mudcats, Shovelhead Cats, and Johnny Cats.

Appearance

Flathead catfish are usually yellow to brown. As the name suggests, they have flat heads. Mottled and spotty ventral sides are common. Their underside is usually a creamy, pale yellow. Unlike some species, a squared-off and flat tale is characteristic of the breed. The distinctive lower jaw protrudes further than the upper jaw. They have a short anal fin with 14 to 17 spines.

Flathead cats can reach up to four feet in length. A respectable weight would be around 40 pounds. Some will also exceed 100 pounds. The largest ever caught weighed 123 lbs. It was caught in Elk City Reservoir, Kansas.

Habitat

Flatheads prefer to live in large bodies of water. Things like reservoirs and ponds. They can also be found in large rivers and tributaries. Unlike blue catfish, flathead catfish prefer slow-moving water. The geographic range includes the Mississippi River and the Great Lakes. You can catch them in Texas and most of the southern states. The Midwest is also home to a large population.

Fishing

Flathead catfish respond best to live bait. Smaller fish like perch, bluegill, and goldfish make great bait. Despite their love of live bait, cut bait also works. Their natural diet consists of small fish and invertebrates. Worms, crayfish, and insects all feature in their diet.

Channel Catfish or Ictalurus Punctatus

Channel catfish are the most abundant species of catfish in North America. Millions of anglers go out in search of these fish every single year. They’re the state fish of Iowa, Kansas, Missouri, Nebraska, and Tennessee.

Channel catfish are smaller species of catfish than blue catfish or flathead catfish. Their weight rarely exceeds 40 pounds. Length is often around 24 inches. The largest channel catfish came from the Santee-Cooper Reservoir and weighed 58 lbs.

Channel catfish have blue to greenish-grey skin with dark spots. Their bellies are often white or silvery. They have a deeply forked tail. Like other types of catfish, they have four pairs of barbels around their mouths.
