The Atlantic Cod is a coldwater fish that was once plentiful along the continental shelf of the Northern U.S. and Canada.
A bottom dweller, cod are opportunistic feeders which will eat a variety of fish, crabs and other invertebrates. While cod can grow to be more that 6 feet long and weigh more than 200 pounds, most adults will average around ten pounds.
They are generally found in depths of 60 to 1500 feet but will go shallower during the breeding season where each breeding female will release her free floating eggs which may number in the millions. Assuming that the eggs are successfully fertilized, only a small number of the resulting fry will survive to become adults.
The cod's delicate white meat is high in protein and low in oils, which makes it possible to preserve the fish for long periods time without becoming rancid by drying and curing it with salt.
In the days before canning and refrigeration, salt cod was traded throughout the World where it became a major food staple in North America, Europe, and the West Indies. It was the increasing demand for salt cod that was an early driver in the colonization of New England and the Canadian Maritime.
New and aggressive fishing technologies in the 20th century caused this seemly inexhaustible natural resource to collapse by over harvesting not only cod but its food sources as well.
