A fish

Cod

Cod is a marine fish of the cod family. It has a greenish-brown color with brown spots and a white abdomen.

The size of the cod depends on its age: the length reaches 1.8 - 2 meters, while the mass of fish caught varies from 4 to 12 kilograms. This fish has a mustache on the chin, three dorsal and two ventral fins without spiny rays, mobile intermaxillary, maxillary bones. Its scales are cycloid, gills comb.

According to the structure of the fins, the representatives of the cod-like family are similar to the carp-like, and in the position of the ventral fins, they are similar to the perciform.

Historical information

For over a thousand years, cod plays an important role in the history of Europe and America. The Vikings who lived in the Lofoten Islands consumed dried fish. Immediately after the catch, it was hanged in an open, well-ventilated area, after three months the carcasses were beaten until the meat was soft and edible. Such nutritious food was stored for a long time, which was ideal for a wandering tribe.

Then the fish gained popularity in Europe because of religious motives: unlike meat, it could be eaten during fasting.

In the period from 1958 to 1976, a diplomatic conflict arose due to cod. The reason for the controversy was the introduction by the first state of the economic 200-mile zone around the island, which prohibited fishing in Icelandic waters, where British fishermen threw nets.

Interestingly, the maximum mass of the largest cod caught in history was 96 kilograms.

Characteristic

The fish habitat covers the Atlantic Ocean (Baltic, White Sea, Arctic cod). In the east of the Atlantic, it is distributed from Spitsbergen and the Barents Sea to the Bay of Biscay, in the west - from Greenland to Cape Hatteras. In particular, it lives in the Norwegian Sea, the Pacific Ocean, off the coast of Iceland. Interestingly, under the trade name cod, only two species of fish are most often found - Pacific and Atlantic. The Baltic, White Sea, Greenland are in less demand.

Cod is able to withstand low temperatures (from minus 1 degree Celsius and below). Her life span reaches 25 years.

The young individual feeds on mollusks, small crustaceans. At the same time, by the age of three, she becomes a real predator and begins to eat other fish: capelin, pollock, herring, her own young. For the extraction of cod, fixed and purse seines, snurrevods, bottom and pelagic trawls, longlines are used.

This is a prolific fish, which begins to lay offspring in March-April, making lengthy 1,500 kilometer migrations to places of spawning. Cod spawns in the water column, its amount can reach up to 2 million in a few weeks.

In 1992, the government of Canada imposed a moratorium on fishing because of a sharp reduction in the number of individuals and the threat of complete extinction of the species. This is the most important commercial fish, which is the raw material for the manufacture of canned food, a source of valuable fish oil.

Major exporters of cod: Canada, Denmark, Great Britain, Norway, Russia, Iceland.

Beneficial features

The meat of cod fish is very dietary: 100 kilograms of product contains 82 kilocalories, and the set of nutrients is extensive and impressive (see p. "Chemical Composition").

Effect on the human body:

  1. It gives strength, accelerates the recovery of the body after illness.
  2. Increases immunity.
  3. Strengthens teeth and bones.

Cod liver

This is an expensive northern delicacy, which owes its popularity to a bright individual taste, unique properties, high nutritional value, and compatibility with numerous dishes. It can be eaten as an independent product or combined with stews, mashed soups, salads and sandwiches.

The main distinguishing feature of cod liver is the absence of heat treatment during canning. Interestingly, for the manufacture of most canned food, fish is boiled, pickled or smoked. This leads to a partial or complete loss of vitamins, macro- and microelements. Cod liver is laid in jars exclusively in its raw form and is poured with its own fat. Due to this, the active substances of the offal and piquant taste are preserved throughout the shelf life of the product.

The energy value of canned cod liver reaches 613 calories, the amount of B: W: Y is 3%: 96%: 1% per 100 grams of product.

What is the benefit of offal?

  1. Improves vision, sharpen the perception of light rays in the dark.
  2. Protects the body from carcinogenesis.

  • high content of "bad" cholesterol;
  • heart problems.

Remember, 40 grams of canned cod liver per day covers the daily requirement of the body for healthy fatty acids, compensates for the lack of vitamins necessary to maintain normal functioning of the body, and prevents the development of Alzheimer's disease, arrhythmias and physical exhaustion.

The disadvantages of fish offal include high calorie content, so people who are overweight should abandon its use.

When buying canned food, pay attention to the inscription on the bank.

How to cook cod?

Before cooking, cut off the head, tail, fins of the fish, gut and rinse it. If necessary, cut into pieces, re-rinse under water. When buying frozen cod, be sure to defrost the carcass before cooking in the refrigerator naturally. When using a microwave oven, hot water, the fish will lose its taste and consistency.

You can cook the cod in whole or in slices (in portions). However, the finer the fish is cut, the less nutrients in it will remain after heat treatment. Cod is cooked in a conventional pan, double boiler, slow cooker, pressure cooker.

Recommendations for the preparation of sea fish:

  1. You can lay cod both in cold water and in hot. In the first case, there is a guarantee that the stiff fish meat is cooked evenly.
  2. When laying cod in an ordinary pan, water should completely cover its surface.
  3. After defrosting, meat should not be re-frozen.
  4. You can cook fish under a closed or open lid.
  5. To enhance the taste of cod, add cucumber pickle, tomato paste, citric acid, salt, carrots, onions, peppers or spices to the water.
  6. Fish is boiled exclusively in gutted form.
  7. Throughout the entire period of cod preparation, constantly monitor the fire: at first it should be strong, when the water boils, reduce it to an average level, reduce it in the final stage so that it is weak.
  8. To maintain the structure of the fish in boiling water, add 15 milliliters of vegetable oil.
  9. In the absence of suitable kitchen equipment, you can cook cod in a deep pan, periodically adding water. In this case, the process of preparing sea fish will not differ from the traditional method.

The duration of cod cooking depends on the size of the carcass (sliced) and averages 15 minutes. Small pieces will reach readiness in 5 minutes. The fastest way to cook fish is in a pressure cooker. And the time of its preparation in a double boiler, slow cooker will not differ in any way from heat treatment in a conventional pan. The readiness of cod can be checked on the basis of two factors: the ease of separation of the fillet from the skin and bones, the degree of meatiness of the meat.

Remember, regardless of the size of the portion, the fish boiled for the baby is cooked for at least 20 minutes, then crushed to a creamy state and carefully checked for the presence of cartilage, bones.
