You really don't want crushed rock.. pea gravel or sand is better than sharp-edged crushed rock. Again, pea gravel would be my first choice because it doesn't tear the fish up and it provides some very small areas for fry to lay in the first few days.
Might also look at the "forage pond stocking recommendations" thread. Lusk explains the concept of basically exactly what you are looking for.
