Shad are anadromous, meaning they live in the ocean and spawn in freshwater rivers. From May to early June, they migrate to the tidal freshwater rivers where they were born to spawn. Spawning takes place between dusk and midnight. After spawning, adults either die or return to the ocean. Once they hatch, young grow rapidly as they gradually move downstream. In autumn, most young leave the Bay for the ocean. Hickory shad live 6 to 10 years.
