a member of ictalurus genus of american catfishes, channel catfish have top-end size of 40–50 pounds (18–23 kg). world record channel catfish weighed 58 pounds, , taken santee-cooper reservoir in south carolina, on july 7, 1964. realistically, channel catfish on 20 lb (9 kg) spectacular specimen, , catfish anglers view 10-lb (4.5-kg) fish admirable catch. furthermore, average size channel catfish angler expect find in waterways between 2 , 4 pounds.

channel catfish coexist in same waterways close relative, blue catfish, less common, tends grow larger (with several specimens confirmed weigh above 100 lb).

as channel catfish grow longer, increase in weight. relationship between length , weight not linear. relationship between length (l, in cm) , weight (w, in kg) species of fish can expressed equation of form:
