Ever watched any of those crazy noodling videos online where people grabbed catfish with their bare hands and wondered, “is noodling legal in my state?”
Catching fish like this with your bare hands may seem crazy, but it’s possible when you noodle for catfish. We always tell people, “if you like the idea of sticking your hand into a dark hole, to see if something bites down hard on it, then you’ll love noodling!”Now that you know whether or not it’s legal in your state, would YOU try it?
When Fishing The Traditional Way Just Won’t Cut It…
Fishing with a rod, reel and bait… it’s a lot of fun. But, what if you used your hand for the bait!
That’s right, when you “noodle” for catfish, you’re sticking your hand into a hole and seeing if a catfish will bite, so you can pull it out!
If this sounds like a rush to you, and if noodling is legal where you live, then maybe you should try it for yourself!
The blue catfish (Ictalurus furcatus) is the largest catfish in North America and is a very interesting species in general. In this article, we will take a deep look at this species, its’ anatomy, and its’ behavior.
Blue Catfish (A General Description)
Some distinctive features of the blue catfish are its body shape, color, jaw and fins. (photo credit: Tennessee Aquarium – tnaqua.org).
Blue catfish have a blue-gray coloration and have wide and stocky bodies.
One of the key physical identifiers of a blue cat is a distinct and noticeable dorsal hump when it becomes a mature fish, which is a good anatomical feature to distinguish a blue catfish from a channel catfish.
The tail of the blue catfish has a deeply notched fork.
Other catfish in North America have a lower protruding jaw, but blues have an upper protruding jaw which is another observation you can make to distinguish between catfish species.
The blue catfish features barbels, or “whiskers,” which are present on all catfish species in North America.
The number of anal fin rays is also different from that of a channel cat. Blue catfish anal fin rays will vary from 30-36 rays, while channel catfish only feature between 25-29 rays.
Blue catfish (pictured here) are sometimes mistaken for channel catfish (below picture) as a result of having a similar appearance in the bodies of water where both are found.This occurs more often when trying to determine the species of the fish when they are juveniles.
The most well-known waters the blue catfish calls home would be the Mississippi river system and its branches and tributaries, which include the Arkansas, Missouri, Tennessee, and Ohio rivers, along with their tributaries and nearby smaller bodies of water.
The rivers listed above aren’t the only rivers to hold native populations, other rivers, such as the Rio Grande river and the Des Moines river in Southern Iowa, also have prominent populations of blue cats.
Interestingly, the blue catfish range extends farther south than most people in the United States are aware of, farther than any other catfish prominently found in North America, and extends throughout the Gulf coast of Mexico and continues south to the countries of Guatemala and Belize in Central America.
Blue catfish have also been introduced into many bodies of water outside where they are found historically, expanding their range and giving anglers more opportunities to catch the fish.

Blue Catfish Diet
The blue catfish has a diet comparable to all catfish species, and they will feed on various species such as frogs, mussels, crayfish, small to medium-sized fish like bluegills and bullheads, minnows, and other aquatic and semi-aquatic prey like small land mammals and birds.
Blues are opportunistic feeders like all catfish and eat virtually any animal or edible animal parts that is the appropriate size.
One interesting food choice…The blue catfish also feeds on the blue crab, a valuable species for the economy around the Chesapeake Bay. Blue crabs are the most valuable species in economic fisheries for seafood, and the number of blue crabs has suffered due to the introduction of blue catfish.
Blue cats prefer easy meals, such as animals that are already dead or wounded, this is the main reason the fish will gather near any hydroelectric dams to feed on animals and fish that have been pulled through the spillways.
Anglers who fish for blue cats favor using live bait like bullheads or cut bait from various fish species like shad, skipjack, bullhead, bluegills, and others. Some anglers also use various other types of bait, like chicken liver or a mixed catfish bait recipe that is thick, smelly, and has a consistency of something like peanut butter.
According to NOAA Fisheries, mature blue catfish will typically be less than two feet long. However, blue catfish can grow to be even 5 feet long and weigh in over 100 pounds!
Most adult blue cats, like this one pictured, tend to be less than 24 inches in length, but they can get huge… over 100 pounds!

Invasive Species
Blue catfish is a very adaptable species that can tolerate a wide range of environments, which means that in some places where they have been intentionally or accidentally introduced, they can have negative effects on the ecosystem.
They can even tolerate water with salinity levels, such as tributaries and brackish water areas leading to the ocean.
In certain waters in Virginia, the blue catfish was purposely introduced in the 1970s, the population quickly exploded and has caused issues with the native species to this day.
In the tidal rivers leading to the Chesapeake Bay, the blue catfish has become the dominant predatory species, out-competing other species native to the waters.
Small fish species like alewives, anadromous shad species, and blueback herring have seen massive drops in numbers due to predation from the blue catfish.
There is a bit of a silver lining to the blue catfish issues in Virginia waterways, as the catfish also feed on the Asian clam and hydrilla, both of which are also invasive species. While they help keep these invasive species in check, it’s difficult to say whether this outweighs the effects the fish has on native species.
Like all fish, the blue catfish has preferences in its habitat, and to successfully catch them, you have to be in the right place at the right time.
As mentioned earlier, your best choices for bait selection will typically be live or cut bait, with cut bait being the most prominent selection. When fishing in locations holding blue cats, cut bait utilizing herring, shad, bullheads, bluegills, or manhaden is sure to seal the deal on one!
Commercially produced stink bait, chicken liver, and other smelly types of bait are the favorite of many anglers, and some swear by their effectiveness over live or cut bait in certain fishing situations.
Blues like deep holes in the river systems they inhabit, so be sure to search out any holes that are 15-25 feet in depth, along with any depressions in otherwise flat and shallow areas that are in the 10-12 foot depth range.
If there is timber present on the edges of holes or in the hole itself, be sure to add it to the top of your hit list, and even areas with rocks, rip rap, and boulders can consistently hold big blues. Maybe you can put a hook N1!
It’s a great idea to run as many rods as you legally can for blue cats, covering a fairly wide area and running a variety of bait options.
Not only does having multiple lines help you contact more fish, but running different bait options not only allows you to figure out what the fish are keyed into on any given day, but you can also adjust your offerings based on what they want.
Blue catfish can get huge and are vicious predators in the waters they inhabit. Understanding the fish, its environment, behavior, and anatomy can help you be consistent on the water when pursuing them, and the results can be epic.
North America has several different species of catfish, with a few being well-known among anglers and others that are a bit more obscure, or less desired, as a prized catch.
So, let’s take a look at the different types of catfish in North America (and one bonus catfish!)
Flathead Catfish

The flathead catfish is also popular with those who prefer to catch catfish by hand (called “noodling”).
General Description
Flatheads have an olive base coloration that features mottled brown and black splotches along their flanks for camouflage, this coloration giving way to a white or yellow colored belly.
The flathead catfish typically has an olive-colored skin with brown and/or black splotches that can vary based on the color of the water they live in.
Depending on the bodies of water they inhabit, such as stained or murky water or clear water environments, the darkness and coloration of the flathead catfish can vary.
Flathead catfish can grow to very large sizes compared to other freshwater fish in North America, with a length of 60+ inches and a weight of 100+ pounds or more being possible, depending on their environment and available forage.
Flatheads can grow very large and provide an epic fight, whether caught with a fishing pole or even by hand (noodling).

Distribution
The flathead catfish has a range that extends from the very southern parts of Canada throughout the Great Lakes region and as far south as Northern Mexico.
Flatheads can be found throughout the Appalachian range, Ohio, Mississippi, and Missouri basins, the Gulf coast states, and as far west as Texas.

Diet of the Flathead Catfish
The diet of flathead catfish mostly consists of live prey, as that is what they prefer to feed on. They will eat most live prey, from insects, and crayfish, to various fish species like bluegills and even smaller catfish, including other flatheads.
Flatheads feed on various forms of prey, including bluegill like this one.
They will also feed on other prey if the opportunity presents itself, including small birds, frogs, and small land animals that may fall or swim into the water.
The flathead, like most catfish, has small eyes in proportion to its’ body, which is a clear indicator that the fish does not rely on its’ eyesight as a predominant method for feeding or catching prey.

Channel Catfish
The channel catfish is the most numerous true catfish species in North America, with a large distribution. They are very popular among anglers, and while they are numerous, they do not reach the sizes of the flathead and blue catfish species (photo credit Texas Parks and wildlife – pwd.texas.gov).
General Description
Like with flathead catfish, the coloration of the channel catfish can vary, and in the case of the channel catfish, they can have an olive, light brown, or grey coloration depending on the body of water.
Some channel catfish may feature speckles or mottled colorations, while others may not feature any additional markings at all.
The top end of the size and weight for that channel catfish, while still large compared to other freshwater fish, is much smaller than the blue and flathead catfish, with 40 to 50 pounds in weight being the typical maximum.
The average weight and length for a channel catfish caught in any given body of water is around 2-4 pounds and 12-26 inches in length.
Channel catfish can be found in the Nearctic of Canada and are widespread throughout southern Canada. The channel catfish is found throughout the eastern two-thirds of the United States as well as the northeastern coast of Mexico.
The Channel Catfish has also been introduced to waters outside of their native ranges, such as states in the U.S. like California and in landlocked bodies of water in Europe, most notably in the Czech Republic and Romania(photo credit: University of California Agriculture and Natural Resources – calfish.ucdavis.edu).
Europe isn’t the only place with bodies of water hosting stocked populations of channel catfish, they can also be found in parts of Malaysia and Indonesia in Southeast Asia.
Like other species of catfish, the diet of the channel catfish is quite diverse, and they will feed on everything from small fish like perch and sunfish to snails, worms, insects, crayfish, frogs, small birds, and small mammals.
Channel catfish will also feed on other food sources like algae, nuts, seeds, grains, and aquatic plants.
Blue Catfish
The blue catfish is the largest species of catfish in North America, but compared to the channel catfish, they inhabit a much smaller range (photo credit: Tennessee Aquarium – tnaqua.org).
Smaller blue catfish are often misidentified as channel catfish due to their coloration, which at times is very close to the gray coloration of some channel catfish.
Blue catfish have a blue-blueish-gray coloration and have a very bulky and wide body shape. The fish features a prominent dorsal hump on its back when they get to adult size, which is a great identifier.
Whereas flathead and channel catfish and a lower protruding jaw, the blue catfish has an upper protruding jaw, along with the barbels that are the characteristic feature of all catfish.
The tail is deeply forked on the blue catfish, and a failsafe way to identify a blue catfish is to count the anal fin rays. The blue catfish has anywhere from 30-36 rays, while channel catfish have 25-29 fin rays.

Distribution
The main region of waterways hosting blue catfish is the Mississippi river and its’ tributaries, which include the Tennessee, Ohio, Arkansas, and Missouri rivers.
Some other rivers hold native populations, such as the Des Moines in Southern Iowa and the Rio Grande river.
The blue catfish range also extends far south, farther than any other catfish in the United States, and follows the eastern coast of Mexico to the countries of Belize and Guatemala.
Blue catfish have also been stocked in many different reservoirs and lakes throughout the southeastern United States.

Diet of the Blue Catfish
The diet of the blue catfish consists of mussels, small fish, crayfish, frogs, and other semi-aquatic and aquatic prey. Blue catfish are opportunistic feeders like all catfish, and will eat almost anything that is deemed edible.
Blue catfish prefer to eat food that is already dead or wounded and will congregate near the spillways of dams to feed upon fish and animals that are disoriented, killed, or wounded from going through the spillways
Bonus Catfish: The Wels Catfish
We decided to add a very interesting catfish to this discussion, and while they are not in North America, catfish anglers in the states can appreciate the Wels catfish simply for what it is (photo credit: Watershed Council – watershedcouncil.org).
General Description
The Wels catfish can grow to incredibly large sizes, with reports of massive fish weighing 440-550 pounds recorded in the last two centuries.
The fish, on average today, can reach lengths of 5-6 feet, and fish weighing well in excess of 100-150 pounds are still somewhat common.
The anatomy of the Wels catfish is quite different from the catfish in North America, and the body drastically tapers with a very large head narrowing down towards the tail.
The anal fin of the Wels catfish is much longer than those of other catfish as well, with the anal fin following half the length of the body.
The Wels catfish is the largest freshwater fish in Europe and Western Asia.
Distribution
The Wels catfish can be found throughout most of Europe and is a dominant fish species in all of Eastern Europe (photo credit: deviantart.com)
The range of the fish extends from Europe to the northern regions of the Middle East and continues eastward into western Asia, with large populations in Iran, Turkmenistan, Uzbekistan, and Kazakhstan.
Catfish that can reach the size of the Wels catfish can eat larger prey like ducks, birds like pigeons, and small to mid-sized land animals, snakes, and fish of varying sizes.
There have been reports of the Wels catfish feeding on people’s pets.
There you have it, the general information on the three main species of catfish in North America, plus the bonus Wels catfish, which holds a legendary status in the regions where they are found.
