Catfish are a diverse group of fish, and as an angler, you're in luck because there are many species to target. The Channel Catfish is one of the most common species found in North America.
They can be found in a variety of habitats, including rivers, lakes, and reservoirs, and are known to be aggressive feeders. Channel Catfish can grow up to 20 pounds in weight and are prized for their flavorful flesh.
The Blue Catfish is another popular species among anglers, known for its impressive size and strength. They can reach lengths of up to 4 feet and weigh up to 100 pounds, making them a formidable opponent.
The Flathead Catfish is a bottom-dwelling species that's often found in areas with rocky or sandy substrates. They're known for their broad, flat heads and can grow up to 50 pounds in weight.
Types of Catfish in the US
The channel catfish is a large fish that usually inhabits large rivers and lakes, with a maximum size of 35 inches and a Virginia state record of 31 pounds, 8 ounces.
The blue catfish, on the other hand, is the largest species that U.S. anglers will encounter, with 100-plus pounders being somewhat common.
A notable difference between the two species is that blue catfish have a straight-edged anal fin, whereas channel catfish have a slightly rounded fin.
The Big Three
The Big Three of catfish in the US are channel, blue, and flathead catfish. They're the most sought after by serious anglers and are the biggest species in the country.
Channel, blue, and flathead catfish can grow to impressive sizes, with two of the three species - blues and flatheads - capable of topping the 100-pound mark. This makes them highly desirable as hard-pulling trophies.
The big three catfish species are a thrill to catch, and their size and strength make for an exhilarating experience on the water.

Channel
The Channel catfish is a popular and widely distributed species, found from coast to coast and in most states, including lakes, reservoirs, ponds, and large river systems.
Channel catfish range in color from silver to various shades of gray, and young ones often have black spots on their body.
They can grow up to 40 pounds or more, with the world record weighing 58 pounds, caught in 1964.
Most Channel catfish weigh less than 10 pounds, but some can reach impressive sizes.
Channel catfish are often aggressive and will hit artificial lures, such as jigs and crankbaits, making them a fun catch for anglers.
They can be caught using various methods, including stationary trot-lines, jug-fishing, drifting, jigging, and traditional bank-based tight-lines.
In the wild, Channel catfish typically inhabit large rivers and lakes, and in Fairfax County, specimens were likely pushed out of upstream lakes during high rains or traveled up the streams from larger rivers.
The Virginia state record for Channel catfish is 31 pounds, 8 ounces, and in Georgia, they can easily grow upwards of 20 and 30 pounds.
Blue
Blue catfish can grow up to 5 feet long and 110 pounds in Georgia.
They're found in lakes, ponds, and rivers all over the state, particularly in the Mississippi, Missouri, and Ohio River Basins.
Blue catfish have a distinctive silver/slate blue color and four pairs of black whisker barbels.
They're opportunistic feeders, eating all sorts of native fish and predators, and can be quite aggressive.
At night, they cruise the shallows, hunting for food on sandbars and flats.
In the day, they prefer deep water, faster currents, and sandy bottoms, often hiding near cover or structure.
The world-record blue catfish was caught in 2011 from John Kerr Reservoir on the Virginia/North Carolina border and weighed 143 pounds.
Blue catfish are common in the eastern and southeastern US, but can also be found as far west as California and as far east as the Chesapeake Bay.
Smaller blue cats can be mistaken for channel cats, but have a straight-edged anal fin and no black spots.
Big tackle is highly recommended for subduing these hard-fighting heavyweights.
Larger blue catfish can have a "muddy" taste, and all catfish can carry consumption advisories due to accumulated heavy metals like mercury.
Flathead
The flathead catfish is a behemoth of a fish, with some specimens weighing in at 75-plus pounds. They're found in the larger river systems of the eastern U.S., including the Mississippi, Missouri, and Ohio rivers.
Flatheads can be identified by their rounded tail, flat head, pale belly, and under-slung lower jaw. They have a unique yellowish-brown mottled coloration.
Flatheads are primarily bottom-dwellers, preferring deeper holes and slower current around structure, often logjams. They're active predators that use heavy tackle to catch a variety of large live baits, such as green sunfish and suckers.
In the eastern U.S., flatheads are typically found in waters 15 to 25 feet deep, where they can ambush their prey. They're a favorite among sport anglers, who use heavy tackle to catch them.
Flatheads are one of the "big three" catfish species, alongside channel and blue catfish. They're known for their aggressive fights, making them a prized catch among anglers.
In Georgia, flatheads can weigh over 20 pounds and reach lengths of up to 60 inches. They're a popular catch among anglers, who often target them with live baits like crayfish and smaller fish.

They can be found deep in caves, under logs, and anywhere that's safe.
If you spend time looking for rocky shorelines and bends in rivers, you're likely to find them.

There are three types of bullhead catfish, although their smaller size means they're not as glamorous as some other species. Despite this, they make for fast and enjoyable fishing for anyone.
Characteristics
Channel catfish are easy to distinguish due to their forked tail. They also have a longer upper jaw that protects the lower jaw.
Generally, these catfish are brown on their sides, slate/blue on their backs, and have a white belly.

Habitat
Channel catfish are often found in deep water, whether it's a cave, under a log, or a bend in a river. They tend to avoid territorial fights and can be found in a variety of safe spots throughout the day.
Deep water is a key feature of their habitat, and if you're looking for channel cats, expect to find them in it. If there is no deep water, they're not as likely to be there.
At night, channel catfish tend to move to areas with sandbars and flats near deep water, likely in search of food.
Fishing and Locations
The channel catfish is found in a variety of freshwater habitats, including rivers, lakes, and reservoirs.
River systems are a key location for channel catfish, as they provide a constant flow of water and a mix of sand, gravel, and rocks that they prefer to inhabit.
Channel catfish can also be found in lakes and reservoirs, particularly those with a mix of sand and gravel bottoms.
In these types of locations, channel catfish tend to congregate around submerged logs, rocks, and weed beds.
Flathead catfish, on the other hand, are often found in deeper waters, typically between 10 to 30 feet deep.
They prefer areas with a soft bottom, such as sand or mud, and are often associated with submerged structures like sunken trees or rock piles.
Blue catfish are found in a wide range of freshwater habitats, including rivers, lakes, and reservoirs, and are known to venture into brackish waters.
In rivers, blue catfish tend to congregate around areas with strong currents, such as bends and confluences.
In lakes and reservoirs, they can be found near submerged structures like rocks and weed beds.
The white catfish is a more tolerant species that can be found in a variety of freshwater habitats, including rivers, lakes, and reservoirs.
They are often associated with areas of low water flow, such as backwaters and oxbow lakes.
Frequently Asked Questions
Which catfish is the best to eat?
Channel catfish are a popular choice among anglers and foodies alike, with a preference rate of 50-75% among catfish anglers. They are a whiskered wonder worth trying, but read on to learn more about their taste and preparation.
How do I tell what kind of catfish I caught?
