Description

The skipjack shad is a herring-like fish (Alosidae) from the fresh and brackish waters of eastern North America. The species has a slender, laterally compressed, silvery body with a greenish back and a projecting lower jaw. Unlike many related shads it is mainly a predator: it hunts small fishes in schools, chasing them near the surface and sometimes leaping from the water. It lives in large rivers and coastal waters and migrates upstream to spawn. The species is harmless to humans.
