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.]

The plant is also called service tree, and Juneberry.
