Channel catfish have no scales like bass or trout. Channel catfish have four pairs of appendages about their snout called barbels, sharp spines on their pectoral and dorsal fins, and a forked tail.
Channel catfish grow to an average length between 13 and 21 inches. The average weight of channel catfish is between 2 and 5 pounds. Note these are average sizes. Many 10 to 15 pound channel catfish have been caught. Some exceed 30 pounds.
Catfish have a highly developed sensory system extending over much of their bodies.
When confronted, catfish generally prevail in a predator-prey situation.
Following mating, both male and female care for their offspring until they have attained a size sufficient to fare for themselves.
Channel catfish inhabit cooler, swifter water areas than most species of catfish.
