I have two ponds just over 1 surface acre each. One is strictly stocked with hybrid catfish and the other is stocked with BG and LMB. I put 300 hybrid catfish in the catfish pond and they love the tractor supply feed. (sportsman floating catfish feed). It took them about two weeks to really get used to the automatic feeder. I hand feed AquaMax in the bass pond and they eat it ok but will not touch the TSC stuff at all. I'm going to keep experimenting with different feeds until I can find something that works with the fish and my pocket book. I'm very excited to see what the hybrid catfish look like this time next year.
