A member of the Ictalurus genus of American catfishes, channel catfish have a top-end size of about 40â50 pounds (18â23 kg). The world record channel catfish weighed 58 pounds, and was taken from the Santee-Cooper Reservoir in South Carolina, on July 7, 1964. Realistically, a channel catfish over 20 lb (9 kg) is a spectacular specimen, and most catfish anglers view a 10-lb (4.5-kg) fish as a very admirable catch.

In the wild the channel cat can get up to 40+ lbs.he channel catfish is rarely bought for the purpose of adding beauty to the pond because they donât have great coloring, typically grey or âgoldâ. They also hide most of the time only coming out for feedings. And they will not create better water quality or reduce waste in your pond.
