Freshwater catfish include numerous species. The
most common catfish in North America are channel catfish,
blue catfish, flatheads, white catfish, and the many
varieties of bullheads.
Channel catfish (ictalurus
punctatus) have both spots (sometimes faded in older
fish) and a deeply forked tail. The upper jaw is longer
than the lower jaw and the anal fin is rounded with 24 to
30 rays. The bluish spawning color often causes anglers
to confuse channel cats with blue catfish. The maximum
size for channel cats is around 60 pounds.
Blue catfish (ictalurus
furcatus) lack spots, but have deeply forked tails
and an upper jaw longer than the lower jaw like channel
cats. The anal fin is straight-edged with 30 to 60 rays.
Most blue cats have a bluish to silvery color. Blue cats
are some of the largest catfish in North America, with a
number of cats over 100 pounds recorded.
Flathead catfish (pylodictis
olivaris) have a flat spot between their beady little
eyes. The lower jaw is longer than the upper jaw, the
tail is only slightly notched, and the anal fin is
rounded with only about 16 rays. Flatheads are the other
very large North American Catfish, with numerous recorded
catches over 100 pounds and a recently set world record
of 122 pounds.
White catfish (ictalurus
catus) have a longer upper jaw, no spots, a
moderately-forked tail and a rounded anal fin with 18-24
rays. The maximum weight is approximately 17 pounds,
though white cats rarely exceed 3 pounds on most waters.
Most anglers believe that catfish are
just scavengers. With a sense of smell more powerful than
a bloodhound's, catfish can not only scavenge very
efficiently, they can hunt down wounded prey like a
shark. This scavenger-predator split personality has
resulted in a raging debate among catfish anglers. One
school of thought favors prepared baits (also known as
"stinkbait") that play upon the catfish's
scavenger personality, including dip baits, paste baits,
and specially manufactured nuggets. The other school of
thought focuses on the catfish's predator personality
with natural baits, including live bait, cut bait,
shrimp, freshwater clams, chicken livers and the
venerable nightcrawler. These are certainly not the only
baits that will take catfish, but it is a good place for
any discussion of catfishing to start.
Stinkbait anglers claim that their
techniques produce the most catfish, that the oily scent
trail is as effective as any chum, and that catfish of
virtually any size will respond to the right foul
fragrance. Dip baits require a special lure, usually made
out of soft plastic or sponge, that has lots of ridges,
holes or pockets to hold the super-smelly dip. Many of
these lures are armed with treble hooks, though some
models use double or single hooks. The lure is dipped
into a container of stink bait (store-bought or using a
homemade recipe), usually smushed around with a stick to
pack the bait in well, and then is cast out from shore or
dropped down from a boat. Paste baits are usually
squeezed from a tube into a soft plastic lure with a big
pocket or hole inside and treble or double hooks. Nuggets
are usually threaded directly onto a single hook or onto
each spike of a treble hook. Limburger cheese, wrapped in
cheesecloth and tied to a hook, should probably be
included in this category. Any of these baits can be
rigged on a leader behind a swivel and a sliding sinker,
off a three-way swivel or dropper loop above a weight, or
directly on the main line with split shot.
Natural bait anglers claim that their
techniques produce the largest catfish and often compare
to the numbers of fish that can be caught on stinkbait.
They primarily use single hooks, though treble hook
rigging is possible, and the variety of rigs, swivels and
weights used is essentially the same as those used by
stinkbait anglers. Good live baits depend on the forage
available, but usually include some type of minnow or
shad, menhaden, and bluegill, where legal. The selection
of live bait often depends upon the species of catfish
being sought. For example, many flathead catfish anglers
prefer live bluegill, while anglers targeting big blue
cats or channel cats often prefer live shad, minnows or
menhaden. Big cats will also hit live waterdogs or
crawdads, baits that are usually fished by Largemouth
Bass anglers. Nightcrawlers can also catch catfish, as
well as virtually any other fish that swims, which is why
nightcrawlers remain so popular as an all-around fish
bait. Cut bait can be local baitfish, carp (where legal),
or smelly ocean fish, like mackerel or anchovies. The
variety of ways to cut bait for catfish is very
extensive, but the most common methods include fillets,
chunks, strips, cubes and partially filleted carcasses.
Shrimp, freshwater clams and chicken livers are also
popular natural baits. With the exception of live bait,
many of these baits can be "aged" for a day or
two to add a stinkbait attraction. In the waters where
carp are legal bait, aged carp strips or fillets are
gaining popularity. Aged shrimp have been popular for
years.
There is a growing school of thought
that shows no loyalty to stinkbait or natural baits,
fishing with whichever method happens to be working at
the time and often combining the two. Cut bait or other
dead bait can be dipped or soaked in stinkbait. Many
states allow multiple-hook rigs or the use of multiple
fishing rods, allowing anglers to fish both stinkbait and
natural bait at the same time. Fishing with combined
methods is a good way to attract fish and to learn what
method is working the best.
Other methods include the use of hotdog
chunks and even pieces of ivory soap. Blue catfish will
even hit shiny lures and spinners. Some anglers claim to
have caught blue cats on shiny, bare hooks. These methods
are certainly less smelly than using aged cut bait or
prepared stinkbait.
Catfish will sometimes run with or near
schools of carp and will take the same baits as carp,
including breads or dough baits. They are also often
caught accidentally by anglers using cut bait for striped
bass.
No matter what method is used, catfish
have a natural ability to steal bait, due to the light
and gentle manner in which they often approach bait. Some
anglers use special reels with bait clickers to help
detect the bites. Others set the hook at the slightest
change in the pressure on the fishing line. Treble hooks
are more difficult for catfish to rob, but many anglers
still use single hooks to increase the sport of their
fishing or to make it easier to release unwanted or
undersized fish.
Catfish respond well to chumming, but
it is not legal in every state or on every body of water.
Manufactured chum is available in blocks, cans or bags.
Cheap canned cat food (for the furry, land-dwelling
variety of cats) can be good chum. Finely chopped bait or
even ground-up fish parts can also attract catfish.
Road-kill in a weighted-down, biodegradable bag (such as
a gunnysack) can be very effective.
Catfish can be caught during the day,
but they feed mostly at night. Consequently, many catfish
anglers prefer night fishing, where legal.
Most catfish anglers eat their catch,
since catfish is considered a delicacy throughout much of
the United States. However, a growing group of anglers
practice catch and release, particularly with bigger
fish, in order to promote the contributions of large
catfish to the gene pool.
Bullheads are small catfish (no more
than 8 pounds) with bulbous heads and broad shoulders.
The body tapers sharply from the pectoral fins back to
the tail. The brown bullhead (ictalurus nebulosus)
has dark chin barbels, a square or slightly notched tail,
a rounded anal fin with 20-24 rays, and there are barbs
or spines on the back edge of the pectoral fin spine. The
black bullhead (ictalurus melas) has dark chin
barbels, a slightly notched tail with a whitish bar at
the base, a rounded anal fin with a gray base and 17-22
rays, and very small barbs or teeth on the back edge of
the pectoral fin spine. The yellow bullhead (ictalurus
natalis) has creamy or whitish chin barbels, a
rounded tail, and a more straight-edged anal fin with 24
to 29 rays. There are many other species of bullheads,
including the less-common flat bullhead (ameiurus
platycephalus), snail bullhead (ameirus brunneus)
and spotted bullhead (ameiurus serracanthus).
The largest freshwater catfish is the
wels or danubian catfish (silurus glanis), which
lives only in Europe. It has a wide, flattened head with
only six whiskers (American catfish have eight), a
rounded tail, and a straight-edged anal fin that runs
more than half the length of its body. It is known to
reach a length of nearly 10 feet (3 meters) and a weight
of 440 pounds (200 kg), with individuals reported over
700 pounds.
