If you put apaloosa cat in your pond they could wipe out your whole pond. How much of a predator channel/blue catfish become depends on how much you feed them. I have cleaned large catfish out of fed ponds and found no fish in there belly. I have caught large catfish out of ponds they were not fed and found 3-4 bream. We feed our ponds and we still catch catfish on artificial bass lures that look like fish. In an experiment at the UGA coastal plain station channel cats and crappie were placed together in a pond. The fish were never fed. 2 years later the pond seemed to be fairly balanced. There was no readily visible evidence of any offspring. It was assumed that they were eating each other's offsring. Don't know what happened after those 2 years.
