Three very basic rules of Gizzard Shad. (These rules are subject to change due to the million or so variables you can have in a body of water)

1. Your largemouth bass will do a
little better.
2. You bluegill, redears and other lepomids will do a lot worse.
3. Gizzard Shad smell funny, and if you touch them you'll want to go wash your hands.
