Billplayfoot,
Fwiw, BLUE & FLATHEAD catfish grow MUCH bigger than that. - The largest Blue that I know of was caught by a commercial netter in SC. - It weighed over 120#.
I once SAW a catfish, that swam past my little 10-foot pram that was more than HALF as long as the boat. - I would guess that it was at least 6 feet long & VERY wide.
Also, the late SCOTT R. BROWNING, who was the "underwater pipeline inspector" for Lone Star Steel Company & used SCUBA gear in his job said that there were catfish LARGER than he was (at 6' 3" & well over 220 pounds), "laying under the pipeline" & he also said, "I always detoured around them, as a catfish that size can drown a fellow."
yours, satx
