Abstract

American shad (Alosa sapidissima) spawned from mid-April through early June in freshwater portions of the Hudson River estuary, where water temperatures ranged from 10 to 20C. Most spawning occurred more than 75 mi upstream of New York City. Successive life stages show slight downstream shifts in peak concentration but more widespread overall distribution. Post yolk-sac larvae and juveniles occurred above and below the salt front. Juveniles emigrated in November, when water temperature was 12-15C. Mean length of juveniles in late October and early November was 86-90 mm.
