Walt are these lakes fertile or do you think that makes a difference? Is there not anything that can control the gizzard shad if they start to take over? Can hybrid striped bass grow large enough to make a difference since gizzard shad and hybrids tend to patrol the same waters? Walt I don't know where you rate catfish but I would tell people to be careful about stocking catfish. I was told that they would not reproduce and their numbers could be easily controled but that has not been my experience. They seem to outcompete everything at the feeder.
