Ecology & Habitat

Habitat

Habitat includes calm, shallow marine waters, bays, and estuaries, sometimes brackish or fresh water. Usually this fish occurs in shallow inshore water (e.g., around eelgrass beds, piers, pilings) during the summer; has been taken in water as deep as 146 meters during the winter (Morrow 1980, Eschmeyer and Herald 1991). Pregnant females move to shallow water before giving birth.

Ecology

Found in large schools.

Reproduction

Males mature at birth; juvenile females mate soon after birth. Spawns May-August, mostly June and early July. Delayed fertilization. Gestation 5-6 months, 3-36 young are born in June or July (Morrow 1980).
