Tried it once
I tried setting 6 single lines marked with jugs tied to stumps. Used goldfish & cutbait. Kept hitting the motor because of the shallow water. Always heard the big cats feed close to the bank. Never got one fish, it was hard to set the lines, real hard as the current (Ohio River) would push the boat, then the motor was in the mud-rocks. Had to make up the tags too, then coming back checking them & finding them in the dark was tough, glad I have GPS & waypoints to help.
Anyway, ALL of the 6 lines had their baits cleaned off them. I think I used 9/0 catmaxx hooks. I'm sure circles would be the way to go. In SC there is a limit on how large the gap can be on the circles on trotlines to prevent the big fish from getting caught on them.
I was going to release all the fish, just an experiment to see what, it any would get caught- cats, garrs, sizes, etc.
Don't think I'll try it again anytime soon. Too much like work.
