If you are not careful, you'll end up with a lake that is full of large Gizzards with nothing to feed on them. That is one reason that Hybrid Stripers have been introduced in some smaller lakes in KY (Guist Creek for example). They help to control the shad populations and keep the size down so that other species can also eat the shad.
