Likely would be if they were CC. I'm not familiar with Blue catfish spawning habits so someone else will need to answer that question.
I don't know how much spawning will be a problem if you are going to have LMB to eat the fry. My understanding is LMB will keep CC spawn in check usually because the catfish fry are easy pickings. I will be finding out, because with stumps and concrete ledges am sure there are places for my CC to spawn, so I hope the LMB will control them and not become a problem. I'm in the wait and see stage.
