SIZE:
Approximately 30 cm, up to 82.6 cm.
LIFE EXPECTANCY:
Up to 30 years.
LIFE CYCLE:
Sexual maturity is reached around 6 to 8 years. Formerly, it was around 10 to 11 years.
The female lays its eggs in several batches. Spawning can last up to a month. A female measuring 60 cm can lay up to a million eggs. After being fertilized in the water column, the eggs float to the surface.
When they hatch, the young fish have one eye on each side of their body. Later, they undergo a metamorphosis that shifts their eyes to their right side. As they grow, they settle to the bottom of the ocean, preferring sedimentary areas to bury themselves.
American plaice is a slow-growing species with a long lifespan. Females are larger than males; therefore, there is sexual dimorphism.
