Habitat and Ecology:
Habitat and Ecology
Marine waters or open lake waters except during breeding season. Lake populations overwinter in deep water. See Fay et al. (1983) for details on various specific environmental requirements. Marine populations spawn in quiet portions of rivers (fresh or brackish water) or in small streams, in lagoons behind barrier beaches, or in lakes above influence of tide. Lake populations move into shallow inshore waters or ponds to spawn at night. Larvae occur in or slightly downstream from spawning areas; juveniles may exhibit net upstream movement until leaving freshwater/estuarine nursery areas in summer or fall (or, in some areas, in spring of the next year).
