I'm sure you are like me and would like to actually see the fish. If you want to make sure that they have something to eat you could throw cottonseed planks out in the pond. Fathead minnows, crawfish, and any of your other forage fish would eat the cottonseed planks. I have placed traps out before with the cottonseed concealed where nothing larger than a fathead could actually get to it. Within 24 hrs. the cottonseed would be gone. Also, if you do put out cottonseed planks until they are eaten I guess your catfish would be even less likely to come to the surface to eat. What is the depth and water temp of your pond.
