I've been fishing a private pond that used to be an old sand pit for the past 3 weekends. My dads company bought it as a reserve water supply about 2 years ago. I've only been using nightcrawlers and have only caught bluegills and bass. How do I know if there are catfish in this pond. It is of pretty good size and some parts pretty deep. The water is very clear with baitfish abundant. What should I use to catch some catfish, I thought about using chicken livers. Thanks.
