- Shad \Shad\ (sh[a^]d), n. sing. & pl. [AS. sceadda a kind of fish, akin to Prov. G. schade; cf. Ir. & Gael. sgadan a herring, W. ysgadan herrings; all perhaps akin to E. skate a fish.] (Zool.) Any one of several species of food fishes of the Herring family. The American species (Alosa sapidissima formerly Clupea sapidissima), which is abundant on the Atlantic coast and ascends the larger rivers in spring to spawn, is an important market fish. The European allice shad, or alose (Alosa alosa formerly Clupea alosa), and the twaite shad (Alosa finta formerly Clupea finta), are less important species. [Written also chad.] [1913 Webster]
- Note: The name is loosely applied, also, to several other fishes, as the gizzard shad (see under Gizzard), called also mud shad, white-eyed shad, and {winter shad}. [1913 Webster]
- Hardboaded shad, or Yellow-tailed shad, the menhaden.

- Shad bush (Bot.), a name given to the North American shrubs or small trees of the rosaceous genus Amelanchier (Amelanchier Canadensis, and Amelanchier alnifolia). Their white racemose blossoms open in April or May, when the shad appear, and the edible berries (pomes) ripen in June or July, whence they are called Juneberries. The plant is also called service tree, and Juneberry.
