Due to the rarity of this species, the shad (Alosa fallax) has substantial legal protection.
Appearance: twaite shad are very similar to allis shad. They are members of the herring family and enter freshwater only to spawn. They have a silvery, flattened and typically fish-shaped body. The twaite shad has a more darkened back than the allis shad. A thin fatty membrane covers the front and rear parts of the eye and the lower jaw fits into a notch in the upper jaw. They have a deeply forked tail with large scales at the base. Twaite shad have a number of dark spots behind the gill cover, sometimes up to 10 spots. They have an anal fin ray count of 19-23.
