when i stocked my pond I was told that catfish recruitment was very low and that the numbers could easily be controlled by fishing. That has not been the case for me and my pond. I have trapped them, had them taken out by large groups of kids. removed every fish caught and they are still the number one fish that shows up at the feeder. If you think crappie numbers are hard to control just try controlling catfish. They aren't a bad fish they just really do multiply and take over. as long as you are prepared for that then go ahead.
