Tertop is right, and the eggs are susceptable to sunfish predation also. Even in small city lakes (100 acres or so) you often have to stock sub-adult channel cats to maintain a fishery. Milk cans (worth more as antiques now) and 18" concrete pipe with one end plugged are for large flatheads to nest in. They will defend the opening from sunfish. Channel cats like to spawn along the rip-rap on dams. If I wanted to have CCats in a small body of water, and money was no object, rip rap a shoreline.
