The Atlantic Cod are found in cool temperatures to subarctic waters from the inshore areas. The cod then move to different depths for feeding. In some areas cod move offshore for the summer.
Atlantic cod tend to move in schools, and some groups of cod show extensive migrations.
Cod usually spawn during the winter and spring. This can occur as early as February off northern Labrador, and as late as June off the Grand Banks. The males and females go through a spawning ritual which is when the eggs and sperm are released into the water. The larger the female, the higher the number of eggs released. A female of 51 cm in length can deposit as many as 200,000 eggs.
