Bill what I meant by constrained was that a HSB's mouth opening doesn't get that big...I don't know the exact numbers, but say that average opening is about 3 inches...which might be a 20in fish(?). Then think about the crappie...a crappie with a vertical length of 3in(able to fit in the fish's mouth) might be about 5in. As I've heard from many people on the board, most crappie stunt between 4 and 6 inches...which would be obtimal forage for a hungry HSB. So I figured instead of needing to massive amounts of catching and killing or the overstocking of bass you create an environment where BIG fish can be caught as well as being able to have a healthy crappie population.
