ReproductionThese fish reach sexual maturity at age 3 or once they are 8 to 11 cm in length. They spawn from June to August in the Gulf of St. Lawrence and a bit later in the Maritimes. The fertilized eggs float and hatch 40 hours later at a temperature of 20°C. DietCunners eat mostly molluscs and crustaceans, in addition to marine worms, sea peaches, barnacles, sea urchins, fish eggs and eelgrass. PredatorsTheir main enemies are humans, marine birds and sculpins. HabitatThey live in inshore waters along the Atlantic coast. They are found from Newfoundland to the north as far south as Chesapeake Bay in the United States. They live in shallow salt water, preferably on or near rocky bottoms. They are relatively inactive in winter, hiding in holes and crevices. Ecology, behaviourCunners stop feeding for 5 or 6 months in winter. In ports, they feed on garbage left by humans.
