Channel Catfish
Ictalurus punctatus
(A.K.A. Forked Tail, Blue-channel Cat, Spotted
Cat, River Cats)
Key Distinguishing Markings:
- Channel catfish are members of the bullhead catfish family, Ictaluridae, and are a freshwater species that are commonly found in
estuarine waters.
- Channel catfish are long slender fish with barbels on the chin that
look like long black whiskers. There are four pairs of barbels around
the mouth, two on the chin, one at the angle of the mouth, and one
behind the nostril.
- Channel catfish lack scales and possess an adipose fin, as well as a
single, often serrated spine in the dorsal and pectoral fins.
- The channel catfish is generally gray to greenish-gray on the upper
part of its slender body, silver to white on its lower half and belly
and has a deeply forked tail. Small adults and juveniles have black or
dusky spots on their body.
- Channel catfish typically possess an anal fin with 24 to 30 rays.
Size:
- One of the largest catfish species found in North America and can
weigh near 60 pounds.
- Maryland state tidal water record is 29 pounds 10 oz. It was caught in
the tidal Potomac River near Mattawoman Creek.
- The freshwater record is 27.92 pounds and was caught in the upper Potomac River.
Distribution:
- The native range of channel catfish extends from southern Canada,
through the Great Lakes and central United States drainage system, to
Mexico including all the Gulf states and some of the Atlantic coast.
- However, due to extensive introductions, their current range includes
all of the Pacific and Atlantic drainage systems in the 48 continental
states.
- As a non-native species, channel catfish have become very successful
in tidal and non tidal waters across the state.
Habitat:
- Channel catfish live mainly in fresh water and can be found in the
freshwater portion of the Chesapeake Bay and its tributaries.
- Channel catfish prefer deep pools around logs, rocks and other
structure where they can hide.
Food Preference:
- Catfish are primarily bottom feeders that feed at night.
- Channel catfish are omnivorous, meaning they eat both plants and animals.
- Common food items include aquatic plants and seeds, fish, mollusks,
insects and their larvae, and crustaceans.
- Although channel catfish have poor eyesight, their barbels are
well-equipped with taste buds which help them find food at night and in
muddy waters.
Spawning:
- Channel catfish spawn in late spring when water temperatures reach
75oF and lay approximately 2,000 to 21,000 eggs in turbid tributaries.
- It is not uncommon for the male fish to spawn with more than one female.
- These fish select nest sites in dark depressions, cavities, or
undercut stream banks, or inside crevices, hollow logs, or man-made
containers
- Spawning success is dependent on available cover.
- Upon hatching, catfish fry sometimes aggregate in tight schools after
leaving the nest until suitable cover is found.
- Fingerlings school together during daylight hours and disperse and
feed at night.
