sc,
I'm in about the same situation as you are with my catfish pond. I don't see any sign at all of my catfish or minnows. My fish biologist friend gave me some helpful info. He said I'd not likely to ever see those catfish until the point in time where they get used to feeding which I don't know how long that will take. I know as of now they ignore the food I try to feed them. My friend told me that they were probably getting plenty to eat at the bottom of the pond. He said the minnows were likely consumed. He also said to put a minnow trap in the pond and see what's there. That's what I plan to do.
