chad

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.] (Zo["o]l.) 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]

{Hickory shad}, or {Tailor shad}, the {mattowacca}.

{Shad bush} (Bot.), a name given to the North American shrubs or small trees of the rosaceous genus {Amelanchier} ({A. Canadensis}, and {A. 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}.
