Chances are you’ve come across a Catfish<\/a> or two, whether it was on the end of your rod or on your dinner plate. They’re incredibly common, but don’t mistake that for boring. And don’t assume they’re all alike. That would be impossible, actually, ’cause there are over 3,000 Catfish<\/a> <\/a>species<\/a>. Scientists estimate that number will grow to 5,000 as they continue to discover more!<\/p>

Some Catfish make great sportfishing. Others are a solid meal. And some are popular aquarium pets. Let’s keep things simple, with a quick rundown of the most popular freshwater and saltwater Cats you can catch on your next fishing trip. Believe us, that’s plenty to sink your claws into!<\/p>

Freshwater Catfish Species<\/h2>

Most Catfish are freshwater species found in rivers, lakes, ponds, and reservoirs. These Cats vary in size and some grow surprisingly big (just like real wild cats). With so many kinds swimming around out there, you never know what you might catch. Here are some of the most common and coveted of them:<\/p>

Flathead Catfish (Pylodictis olivaris)<\/em><\/h3>

All hail “Old Flatty” – or “Yellow Cat,” as some anglers call Flathead Catfish. You might say this Cat is the lifeblood of American Catfishing, which swims all the way from the Midwest down to Mexico. <\/p>

You’ll recognize a Flatty by its flat head<\/strong> and muted, green-yellow color<\/strong>. A typical catch weighs 20–40 pounds<\/strong>, but trophies can top 100. <\/p>

Native to the central US, Flatheads are a top target throughout the Mississippi River<\/a> basin. Look for them in slow-moving rivers and reservoirs with plenty of cover. They cuddle up to submerged logs, root wads, and deep holes, usually where the water is warm and muddy. To be honest, you’re likely to find Flathead in pretty much any lake or river that fits the profile for them. But, if you’re in the market for a trophy-sized fish, try your luck in the Ohio River, the Tennessee River system, and the Susquehanna River<\/a>, PA.<\/p>

Size isn’t the only reason Flatheads make great fishing. They’re notoriously picky eaters, which means you really have to work to get a bite out of them. Use live bait<\/a>, such as sunfish, shad, or bluegill to entice the bite. <\/p>

Hook one, and you’ve got an excellent dinner ahead of you. Flathead meat is firm, white, and mild. If you’re fishing for food, try to catch a Flathead under 15 pounds, as these taste the best. <\/p>

Blue Catfish (Ictalurus furcatus)<\/em><\/h3>

Blue Catfish (or simply, “Blues”) are the heavyweights of American Catfish. They’re native to the Mississippi, Missouri, and Ohio River<\/a> basins, but they’re available throughout the southeastern US thanks to stocking programs. Lake Texoma<\/a> and the James River, VA, are two other standout spots for big specimens.<\/p>

True to their name, Blue Catfish have bluish-gray bodies<\/strong>. You can also recognize them by their forked tails <\/strong>and straight-edged anal fins.<\/p>

Blues thrive in strong currents, so the best places to target them are large rivers and reservoirs with muddy bottoms. And, by the way, big rivers breed big Cats. Monster Blues over 100 pounds are pretty common, even though the average catch is 20–40 pounds<\/strong>. <\/p>

Anglers target Blue Cats for their size and pulling power. They’ll hit cut bait, live bait, and sometimes even stink bait. Drift fishing and anchoring near deep holes are effective methods for them. Like Flatheads, Blue Catfish taste best when they’re small.<\/p>

Channel Catfish (Ictalurus punctatus)<\/em><\/h3>

Rounding out the “Big Three” is Channel Catfish, another species native to the central US. Thanks to stocking programs, Channels are probably the most common and widespread species in the country. In addition to the Mississippi and Tennessee River systems, anglers will find good populations in the Red River<\/a>, which runs through North Dakota and Minnesota, and Lake Tawakoni<\/a>, TX.<\/p>

Channel Cats are the kittens of the bunch, averaging just 2–10 pounds<\/strong> but you can catch 20-pounders fairly often, though. These Cats aren’t named for their looks, possibly because not much is notable. They have slender, blue-gray bodies<\/strong> and deeply forked tails<\/strong>. One giveaway if you catch a juvenile fish is a smattering of black spots<\/strong> along the side.<\/p>

These Catfish like relatively large rivers, lakes, and reservoirs with mild currents. Due to their size, they’re great on light tackle. And, unlike Flathead, they’ll bite almost anything: stink bait, cut bait, shrimp, worms – even hot dogs! <\/p>

When it comes to food value, Channel Cats are mild and flaky. Their fillets hold up well fried, grilled, or blackened.<\/p>

Bullhead Catfish (Ameiurus spp.)<\/em><\/h3>
\"A<\/figure>

They may not belong to the “Big Three,” but anglers make quite a ruckus when it comes to Bullhead Catfish. In fact, these are the reason many of us fell in love with fishing to begin with. You may know them by one of their affectionate nicknames, such as “Mud Cats” or “Pollywogs.” <\/p>

There are three kinds of Bullhead Catfish: Brown (Ameiurus nebulosus)<\/em>, Black (Ameiurus melas)<\/em>, and Yellow (Ameiurus natalis)<\/em>. In this case, the name says it all: Browns are mottled<\/strong> in color, Black Bullhead are dark,<\/strong> and Yellows are<\/strong>…well, yellow.<\/strong> Thanks, Bullhead!<\/p>

You can find them in warm, slow-moving waters across the eastern and central US. Try your luck in a local creek, pond, or lake, especially one with muddy or weedy areas. As Bullhead don’t reach trophy sizes, what makes a good fishing spot for them is a lake or river that holds large numbers. Look to the Finger Lakes<\/a> in New York, lakes such as Clear Lake<\/a> in Central California, along with Midwestern ponds and swamps or bayous in Texas<\/a> and Louisiana<\/a>. <\/p>

Most Bullheads weigh less than 2 pounds<\/strong>, but a trophy might reach 5. Their size makes them perfect for kids and beginners, not to mention their appetites. Bullheads will take the most basic baits out there, including worms, cut bait, and doughballs.<\/p>

They make good eating when cleaned properly. Just be sure to handle them with care, because they have sharp spines.<\/p>

White Catfish (Ameiurus catus)<\/em><\/h3>
\"A<\/figure>

Away from the muddy waters of the central US, you’ll find White Catfish. This species is native to coastal rivers along the Atlantic, from New York down to Florida and into the Gulf states. Out west, you can find them in parts of California where they’re stocked artificially.<\/p>

As coastal fish, they show up in brackish waters as well as slow-moving freshwater, typically in areas with a muddy or sandy bottom. <\/p>

While the name “White Catfish” paints a pretty picture, these fish aren’t exactly white. They’re gray<\/strong>, with white bellies<\/strong>. Like many Catfish, they have broad heads and noticeable barbels. One thing that makes them a little unique, however, is their rounded tail fins.<\/strong><\/p>

White Cats range from 1–10 pounds<\/strong>. They’re aggressive feeders, despite their size, and this makes them another great target on light tackle. They often bite shrimp, worms, cut bait, and chicken liver, and their fillets are mild and flaky, especially when cooked fresh.<\/p>

Wels Catfish (Silurus glanis)<\/em><\/h3>

Further afield, you have Wels Catfish<\/a> (aka “Sheatfish”) – one of the biggest freshwater Cats in the world. These monsters hail from Eastern Europe and have forged their way across the entire continent. Today, you can even find them in parts of Asia.<\/p>

Wels Catfish prefer large, warm rivers and deep lakes with plenty of cover. They regularly top 100 pounds<\/strong>, positively dwarfing most American Catfish. There are even reports of some Wels that weighed as much as 300 pounds! <\/p>

In case the size of these lunkers isn’t enough, you might recognize them based on their fins. Wels have long, fan-like anal fins<\/strong> and a single, rounded tail fin<\/strong> – similar to species such as Bowfin and Burbot. But, trust us: you’ll know it’s a Wels because the fish will be bigger than you.<\/p>

It goes without saying that these Cats offer a serious challenge. You’ll want to pack heavy tackle and maybe even consider trolling with a small boat like a kayak. You can entice a bite using bait fish, cut bait, or artificial lures. <\/p>

Finally, Wels are a trophy much more than table fare, though juveniles are passable when cooked fresh.<\/p>

Giant Mekong Catfish (Pangasianodon gigas)<\/em><\/h3>

If you thought it couldn’t get any bigger than Wels, just wait – Mekong Cats are about to claw their way to the top. This species from Southeast Asia is, in a word, legendary<\/em>. Anybody serious about trophy hunting simply has to catch one. <\/p>

Mekong Catfish typically weigh 100–200 pounds<\/strong>. In the wild, however, they have the potential to top 600. Yes, twice the size of a measly little Wels!<\/p>

It’s no surprise that these big Cats love big rivers, especially the deepest sections where the current moves slowly. What will surprise you, though, is their diet. Mekong Cats are actually herbivores. <\/p>

Catching one is a feat. Rather than targeting them in the wild, anglers usually focus on fishing for Mekong Catfish in controlled environments like Thailand’s<\/a> fishing parks. They’ll supply you with special dough balls or vegetable-based baits to get them to bite.<\/p>

Mekong Catfish aren’t very good to eat, which is just as well because they’re protected from harvest in many areas.<\/p>

And here’s one more thing that makes them unusual: adult Mekong have no barbels!<\/strong><\/p>

Saltwater Catfish Species<\/h2>

As we mentioned, there are over 3,000 species of Catfish. Of these, a very small percentage live in saltwater. This little pride of sea Cats belongs to its own family called Ariidae. <\/em><\/p>

Saltwater Catfish look pretty much like any other Catfish. But you’ll find that they’re a tougher bunch. Their marine habitat has hardened them, resulting in bigger spines and rougher fights. (That’s what comes from rubbing shoulders with predators like Sharks.)<\/p>

Hardhead Catfish (Ariopsis felis)<\/em><\/h3>
\"Two<\/figure>

Hardhead Catfish are common along the Gulf of America and southeastern Atlantic coasts. So common, in fact, that they’re a bit of a nuisance. <\/p>

Hardheads eat almost anything, from shrimp and squid to cut bait. They often steal these off the end of your line when you’re trying to catch more desirable species like Redfish or Speckled Trout. <\/p>

They usually weigh 1–3 pounds<\/strong>, but can reach 5 pounds. They’re distinguished by their gray-green color, long barbels, and – most notably – a hard bony plate<\/strong> on their head.<\/p>

If these Cats were good eating fish, anglers might not mind catching them. But, unfortunately, their meat isn’t all that flavorful.<\/p>

Gafftopsail Catfish (Bagre marinus)<\/em><\/h3>
\"A<\/figure>

Gafftopsail Catfish are named for their tall, sail-like dorsal fins.<\/strong> You’ll commonly hear them called by simpler names such as “Gafftops” or “Sail Cats.”<\/p>

They inhabit the same range as Hardheads, along the Gulf of America and the Atlantic. But, when it comes to looks and size, they’re several notches above. <\/p>

Typically weighing just 2–4 pounds<\/strong>, Gafftops can grow up to 10 pounds. In addition to the sails on their backs, they’re distinguished by long, trailing pectoral fins<\/strong>. They also have a slimy coating and venomous spines, so handle with care.<\/p>

Gafftops put up a real typical cat fight, attacking shrimp, squid, or cut bait with gusto. As for eating, opinions are mixed. Some say they’re delicious when filleted and fried, while others find them too fishy. If you catch one and decide to eat it, bleed and ice it immediately.<\/p>
