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 territory is where the courtship of the female takes place. Males and females, swimming very close together, release their sperm and eggs into the water. Fertilization takes place externally. Both sexes can mate more than once a day.
The eggs float to the surface and hatch two or three days later.
Young cunner generally have a black spot on their dorsal fin.
