Appearance

Breeding Biology

Spawning usually occurs in November or December, when waters reach roughly 7.8oC. In very cold areas such as Labrador, these fish may only spawn once every two to three years. Spawning usually occurs in shallow waters at depths no greater then 25 feet. Spawning substrate is normally a rocky bottom or shoals.

The number of eggs a female releases varies depending on her size and latitude, but is estimated at about 8,000 to 16,000 eggs, which are randomly deposited over the spawning grounds. Spawning usually occurs at night, with both males and females forming large schools. Eggs hatch in about 140 days.
