Reproduction and life cycle

Spawning occurs from late May to July at night in the salty waters near the Bay’s mouth. Females may spawn 9 to 60 times and release as many as 3 to 20 million eggs during a single spawning season.

Larvae hatch 18 hours after fertilization. Currents carry them to brackish-water nursery areas (usually shallow bay grass beds). At 6 to 8 weeks old, juveniles begin to form schools with individuals of similar size. They mature at two to four years old. Spotted seatrout can live for 15 to 18 years.
