Reproductive Biology

Studies of closely related species of Crangon reveal that most individuals are protandric hermaphrodites (maturing first as males and then changing to female as they get larger) while some "primary females" remain the same sex throughout life. Eggs are brooded on the pleopods; large egg-bearing females migrate into estuaries in spring and release their larvae, which are carried out to sea, while smaller females release their larvae in the late fall. Larvae pass through seven zoeal stages before settling out; those hatched in the spring migrate to shallow areas where they grow rapidly.
