GADUS MORHUA. The only one that is cod
Cod is a species of white fish that is found in the cold seas near the 0º, in large shoals at depths of 50 metres to 600 metres, although it usually swims at depths of around 150 to 200 metres. It is found mainly in the North Atlantic. Fresh cod is cod that is caught from the end of autumn until spring, although nowadays it is possible to buy cod all year round as it is available in a variety of formats: dry salted; dried; fresh; smoked; and frozen.
Cod, whose most highly prized species comes from the Gadus morhua L family, is known as the “beef of the sea” because of its high protein content, and it is one of the most important and nutritious sources of food found in the sea. Made up of 80% water, it has one of the lowest levels of fat of any fish as well as omega-3 fatty acids, which reduce cholesterol levels. It also contains minerals such as calcium – which strengthens bones, phosphorus – which aids the proper functioning of muscles, and iodine – which plays a role in the production of thyroid gland hormones. It also contains potassium, fluoride and vitamins.
Furthermore, in addition to its nutritional properties, cod has several organoleptic characteristics that make it unique among fish.
