LIFE CYCLE :
Sexual maturity is attained around the age of three.
Spawning takes place from June to mid-August in the Gulf of St. Lawrence.
Males develop a nuptial coloration, which is more pronounced, at the end of winter. They define a territory and defend it fiercely against other suitors. This is where the courtship of the female takes place. Males and females release their sperm and eggs into the water, swimming very close together. Fertilisation takes place externally. Fish of both sexes can mate more than once a day.
The eggs float to the surface and hatch 2 or 3 days later.
