My girlfriend works at a business with a 4 acre pond. Maximum depth 18' to 20', it was dug and stocked in 1991. It's fed by two small feeder branches. The population of bream and bass are well balanced. I've seen several bass over 5 lbs. and have caught plenty of bream from 8" to 10", biggest was 11". There are 7 sterile grass carp in there at least 20 pounds, but they haven't destroyed all the vegetation. I caught one largemouth last spring over 5 lbs. There are supposed to be catfish in there. The first few years after it was stocked, the employees would throw out bread from the dock and there were catfish coming from every direction chomping down on the bread. I only managed to catch one catfish out there in 2009, a 4 pounder. And the catfish don't come to the bread they throw out anymore, but the grass carp and bream do. My question is as much as I've fished there, shouldn't I have caught more than one channel? I've never fished there at night, but have permission. I'm considering offering to pay to stock the pond with channel cats, but do you think I should wait until next spring or summer and try to night fish some before I make the decision?
