Where do true cods and other important gadiform fishes live in the North Atlantic?

Gadiform fishes, which include true cods and their relatives, are primarily marine, bottom-dwelling species. In the North Atlantic, these fishes are widely distributed across continental shelf regions, ranging from shallow inshore waters to depths of approximately 200 fathoms.12

While gadiforms are found throughout the world's oceans, they are most numerous in the eastern North Atlantic. Specifically, the Atlantic cod (Gadus morhua) is a cold-water species found on both sides of the North Atlantic, inhabiting areas from the east coast of North America eastward to the Baltic and Kara seas. Other related forms, such as deep-sea cods (family Moridae) and grenadiers (family Macrouridae), typically occupy deeper habitats along the continental slopes, with grenadiers found at depths ranging from 100 to 1,000 fathoms.12
