Texas is home to at least 10 species of freshwater catfish, but when Texas anglers talk about catching catfish, they’re usually talking about three: blue catfish, channel catfish, and flathead catfish. While there are other types of catfish in Texas the “big three” are the ones you’re most likely to encounter.
Those are the three primary sport catfish species in Texas, and all three can be found in North Texas.
I’ve spent 29 years guiding anglers for catfish in the Dallas-Fort Worth area. On most guided trips, we’re targeting either blue catfish or channel catfish, depending on the season, conditions, and which species offers the best opportunity. Flatheads are caught occasionally while fishing for other catfish, and I also offer limited trips specifically targeting them.
If you’re trying to figure out what kind of catfish you caught—or which species you want to catch—there are a few easy ways to tell them apart.
Texas Catfish Identification at a Glance
| Blue Catfish | Channel Catfish | Flathead Catfish | |
|---|---|---|---|
| Tail | Deeply forked | Deeply forked | Square or slightly notched |
| Spots | Usually absent | Often present, especially on smaller fish | Mottled coloration |
| Anal fin | Straight-edged, usually 30–36 rays | Rounded, 24–29 rays | Shorter and rounded |
| Head | Broad | Narrower than a flathead | Broad and noticeably flattened |
| Lower jaw | Does not project like a flathead | Upper jaw extends beyond lower jaw | Lower jaw projects beyond upper jaw |
| North Texas fishing | Numbers, keeper-size fish and trophy fish | Excellent numbers and eating-size fish | Specialized target with trophy potential |
The easiest first step is the tail.
If the fish has a deeply forked tail, you’re probably looking at a blue or channel catfish. A flathead has a square or only slightly notched tail and a noticeably different head.
Distinguishing a blue from a channel can be trickier. Don’t rely on color alone. Look at the spots, the shape of the anal fin and, when necessary, count the anal-fin rays.
The Three Texas Sport Catfish Anglers Actually Chase
Texas has more catfish species than most anglers realize, including bullheads and several smaller species. But blue, channel, and flathead catfish account for the overwhelming majority of serious recreational catfishing.
They’re also very different fish.
Channel cats are abundant and widespread. Blue cats provide everything from fast action with smaller fish to some of the largest freshwater fish swimming in Texas. Flatheads are powerful, structure-oriented predators that require a different approach.
Here’s what separates them.
Blue Catfish
Blue catfish (Ictalurus furcatus) are the largest of the primary Texas catfish species and one of the fish we’re most likely to target on guided North Texas catfishing trips.
A blue catfish has a deeply forked tail and is generally slate gray to bluish-gray along the back, fading toward a lighter belly. Most blue catfish don’t have the distinct dark spots commonly seen on smaller channel cats.
The best identification feature, however, is the anal fin.
A blue catfish has a relatively straight outer edge on the anal fin and typically has 30–36 anal-fin rays.
How Big Do Blue Catfish Get in Texas?
For everyday fishing, 2- to 10-pound blue catfish are abundant in many Texas waters. Twenty- to 50-pound fish are available in good trophy fisheries, and Texas has produced blue cats far larger than that.
That’s part of what makes blues such a great fish to target.
We can spend one trip catching good numbers of smaller blues and another trip specifically hunting trophy-class fish. They’re the same species, but they’re two very different styles of catfishing.
That’s also why I don’t automatically target blue catfish every day. I fish for blues or channels based on whichever species is providing the best opportunity at that time.
The goal is to put customers on fish, not force a particular species because it sounds better on a website.
How We Catch Blue Catfish in North Texas
Blue catfish are heavily tied to forage, especially shad.
Electronics play a major role in how I locate fish and bait. Depending on the season, we may find blues relating to channels, flats, structure, baitfish or suspended in the water column.
Fresh bait is a major part of consistently catching them.
You can learn more about how and where I target them on my Blue Catfish Trips page. During the colder months, anglers interested in hunting bigger fish can also learn more about Trophy Blue Catfish Trips.
Blue vs. Channel Catfish: What’s the Difference?
This is probably the most common catfish identification problem in Texas.
Both species have deeply forked tails, and color isn’t dependable enough to make the call by itself.
Look for two things:
- Channel catfish commonly have dark spots, although those spots can disappear as the fish gets larger. Their anal fin has a rounded outer edge and typically 24–29 rays.
- Blue catfish normally don’t have dark spots. Their anal fin has a much straighter outer edge and typically 30–36 rays.
If you’re holding a big, dark fish with no obvious spots and aren’t sure whether it’s a blue or channel, look at the anal fin instead of the color.
Channel Catfish
Channel catfish (Ictalurus punctatus) are the most widespread and abundant catfish in Texas.
They’re also responsible for some of the fastest catfishing action we have in North Texas.
Channel cats have a deeply forked tail similar to a blue catfish. Smaller channels typically have scattered dark spots along their sides, although those spots often become less obvious or disappear entirely as the fish gets larger.
The anal fin is the better identification feature. It has a rounded outer margin with 24–29 rays.
Most channel cats caught on my trips are roughly 1–5 pounds, although larger fish certainly occur.
Don’t let the smaller average size fool you.
When the channel catfish bite is good, it’s some of the most entertaining fishing we do.
How We Catch Channel Catfish
My approach to channel cats is different from the way I typically approach blues.
Prepared and punch baits can be extremely effective, and I frequently fish them on lighter tackle. During the right conditions, it’s fast-paced fishing that keeps everyone in the boat busy.
This makes channel catfishing particularly good for families, kids and anyone more interested in catching a bunch of fish than sitting around waiting for one giant bite.
There are times of year when channel cats simply offer a better opportunity than blues. When that’s the case, that’s what we’re going to fish for.
You can learn more on my Channel Catfish Trips page.
Flathead Catfish
Flathead catfish (Pylodictis olivaris) are difficult to confuse with blues or channels once you know what you’re looking at.
The first giveaway is the head.
A flathead has a wide, flattened head with a lower jaw that projects beyond the upper jaw. Instead of the deeply forked tail found on blue and channel catfish, a flathead has a tail that’s square or only slightly notched.
Their coloration is generally yellowish to brown with dark mottling, which is why you’ll hear Texas anglers call them yellow cats.
Flatheads can also get very large. Fish weighing 20–50 pounds occur in Texas waters, and considerably larger fish have been caught.
Catching Flathead Catfish in North Texas
Flatheads behave differently than blues and channels.
They’re heavily associated with structure and cover and are serious predators. Targeting them intentionally requires a different mindset and approach than simply going out and trying to catch numbers of catfish.
We occasionally catch flatheads while targeting other species, but I also offer limited trips specifically targeting flathead catfish.
When I’m intentionally targeting them, I’ve had a high success rate, but I don’t market flatheads as something we’re going to catch every day on a standard catfish trip. They’re a specialized target.
If catching a flathead is specifically on your bucket list, it’s best to discuss that with me before booking so we can determine whether the timing and conditions make sense.
Other Types of Catfish in Texas
Blue, channel, and flathead catfish get most of the attention, but they aren’t the only catfish swimming in Texas.
Texas has at least 10 freshwater catfish species.
That includes several species of bullheads and madtoms along with less familiar catfish that most recreational anglers rarely encounter. Bullheads can sometimes be mistaken for small flatheads, but their heads are more rounded, and the lower jaw doesn’t project forward like a flathead’s.
Texas coastal waters also contain hardhead and gafftopsail catfish.
Those are saltwater species and have nothing to do with the catfish we’re targeting on guided North Texas lake and river trips.
For the average freshwater angler in Texas, it’s much simpler to remember this:
Blue, channel, and flathead catfish are the big three.
Learn to identify those three, and you’ll be able to identify virtually every catfish that matters on a typical North Texas catfishing trip.
Where We Catch Catfish in North Texas
North Texas Catfish Guide Service fishes several lakes and rivers in the Dallas-Fort Worth region. The exact water I fish can depend on the season, conditions and type of trip.
Eagle Mountain Lake
Eagle Mountain Lake is my primary lake and one I’ve spent decades fishing.
It offers excellent opportunities for both blue and channel catfish. Flatheads are also present, and we occasionally catch them while fishing for other species.
Because I spend so much time here throughout the year, Eagle Mountain gives me the flexibility to change species, locations, and techniques as conditions change rather than being locked into one style of fishing.
Lake Worth
Lake Worth has an excellent catfish fishery, including blue, channel, and flathead catfish.
My Lake Worth guided trips are catch and release only.
There is also an official fish-consumption advisory covering Lake Worth and portions of the West Fork of the Trinity River upstream toward Eagle Mountain Lake. Anglers should always check the current Texas Department of State Health Services and Texas Parks & Wildlife information before consuming fish from waters covered by an advisory.
Lake Lewisville
Lake Lewisville supports excellent blue and channel catfish populations and has the ability to produce very large catfish.
It’s one of several North Texas reservoirs that can provide opportunities ranging from catching numbers of fish to pursuing larger blues when conditions are right.
Lake Grapevine
Lake Grapevine contains blue, channel, and flathead catfish and provides another option for guided catfishing in the DFW area.
As with the other lakes I fish, species and tactics can change with season and conditions rather than following one approach throughout the year.
Lake Ray Roberts
Lake Ray Roberts has a strong blue catfish fishery along with channel catfish and flatheads.
It’s another North Texas lake with legitimate big-fish potential, but the best lake isn’t automatically the lake with the biggest fish in the record book. I look at current conditions, seasonal patterns, and what the customer wants from the trip.
Brazos River
The Brazos River offers a completely different catfishing environment than the North Texas reservoirs.
Blue, channel, and flathead catfish are all present, with flatheads playing a more prominent role in the river fishery.
You can see all of the waters I currently guide on the North Texas Catfish Guide Lakes page.
Which Catfish Trip Should You Book?
You don’t necessarily need to decide on a species before booking.
That’s one of the advantages of fishing with an experienced catfish guide.
If your goal is fast action and plenty of bites, channel catfish may provide the best opportunity.
If blues are active, they can provide excellent numbers of quality fish with the possibility of much larger fish mixed in.
If your goal is specifically a trophy blue catfish, that’s a different trip and is best during the prime trophy season.
Flatheads are more specialized. If that’s the fish you want, contact me before booking so we can discuss timing and availability for a targeted flathead trip.
Most importantly, I don’t choose the species just because one sounds better in an advertisement. I target blue or channel catfish based on what is biting best and what gives my customers the best chance of a successful day.
I’ve been guiding catfish anglers in North Texas for 29 years, and North Texas Catfish Guide Service is the longest-running dedicated catfish guide service in Texas.
All bait, tackle, and fishing equipment are provided. You bring whatever you want to eat and drink and a valid Texas fishing license.
If you’re ready to go fishing, you can check available dates and book a North Texas catfishing trip online.
Frequently Asked Questions About Texas Catfish
How many types of catfish are there in Texas?
Texas is home to at least 10 freshwater catfish species. For recreational anglers, the three most important are blue catfish, channel catfish and flathead catfish.
What are the three main types of catfish in Texas?
The three primary Texas sport catfish are blue catfish, channel catfish and flathead catfish. Channel cats are the most widespread, blue cats grow the largest, and flatheads are large structure-oriented predators.
How can you tell a blue catfish from a channel catfish?
Both have deeply forked tails, so look at the anal fin. A channel catfish has a rounded anal fin with approximately 24–29 rays. A blue catfish has a straighter-edged anal fin with approximately 30–36 rays. Smaller channel cats also commonly have dark spots, while most blue catfish do not.
How can you identify a flathead catfish?
Look for a broad, flattened head, a projecting lower jaw and a square or slightly notched tail. Those characteristics make flatheads relatively easy to distinguish from the deeply forked tails of blue and channel catfish.
What kind of catfish do you catch on North Texas guided trips?
We primarily target blue and channel catfish, choosing whichever species offers the best fishing opportunity based on the season and current conditions. Flatheads are occasionally caught on regular trips, and limited targeted flathead trips are also available.
What’s the best catfish to catch in Texas?
There isn’t one species that’s best for everyone. Channel cats can provide incredible numbers and fast action. Blue catfish offer both numbers and trophy potential. Flatheads provide a more specialized style of fishing for anglers specifically interested in targeting them.
For guided trips, I concentrate less on picking a favorite species and more on putting customers on the best bite available unless you want to specifically target a certain species or size.
