Lake Texoma Fish Species: Grizzard Shad Gizzard shad provide forage for most game species. They rarely bite on a hook, and when they do, they are generally considered worthless as a food fish. The species is often used as cut bait for other fish species. Dorosoma is Greek for “lance body,” referring to the lance-like shape of young shad. The species epithet cepedianum refers to the French naturalist Citoyen Lacepede. Gizzard shad are usually easily distinguished from threadfin shad by the fact that the upper jaw projects well beyond the lower jaw.
