Almost all representatives of the genus cod, with the exception of burbot, prefer to live in salt water. Moreover, reservoirs should be located closer to the northern hemisphere, since their element is cold water.

The cod family includes about 100 species of various fish, and almost all of them are inhabitants of salt sea water, and only one burbot inhabits freshwater rivers and other bodies of water. The most common of them are: haddock, navaga, blue whiting, cod, hake and many others. What are the differences between the cod family and other representatives of the seas and oceans will be discussed in this article.

Appearance

The cod family has a number of distinctive external features. For example, members of this family have multiple dorsal fins and one or two anal fins. The most developed in them is the caudal fin.

Typically, the caudal fin may be integral with the dorsal and anal fins, or it may be separated from them. Interestingly, all of them have no sharp, spiny rays. In fish of this family, enlarged gill openings are noted, as well as the presence of a mustache in the area of ​​the lower jaw. The body of the fish is covered with small scales that are easy to clean. Basically, codfish prefer to move in small flocks, with the exception of burbot, a freshwater representative of this family.

Of the 100 species, absolutely diverse representatives can be distinguished, differing in completely different sizes. Species that feed on plankton are much smaller than those that feed on larger living organisms. The smallest of them is a deep-sea gadikul, which can reach no more than 15 cm in length. The largest representatives include such predators as moths and Atlantic cod, which can reach up to 1.8 meters in length.

Habitat

Representatives of this family are found in almost all waters of the northern hemisphere of the earth, and only 5 species inhabit the seas of the southern hemisphere. All of them should be classified as marine inhabitants living in salt water and, only burbot prefers fresh waters of the north of Europe, Asia and America.

The highest numbers of cod are found in the eastern parts of the Atlantic, including the Norwegian and Barents Seas. Only cod is found in the Baltic Sea. Representatives of cod can also be found in the Black and Mediterranean Seas.

It is unlikely that representatives of this family will be found in the equatorial zone, but as many as three species of this family live off the coast of South America, South Africa and New Zealand.

What do codfish eat?

Some types of fish prefer plant food, while others exclusively animal, because they are predators. Some of them, such as blue whiting, arctic cod, Arctic cod, eat zooplankton.

Alaska pollock and cod feed on fairly large living organisms. In these fish, the fat that they store in the process of feeding accumulates in the liver, which is their significant difference from other fish species that do not belong to this family.

Each species of fish belonging to this family differs in that it has its own characteristics of reproduction. Most of them lay eggs in seawater, although some of them that live in northern latitudes choose freshened areas of reservoirs for spawning. Not most of them enter rivers to lay eggs.

Representatives of this family begin to lay eggs only after 3 years of life, and some of them even later - after 8-10 years of life. They lay eggs for several years in a row, laying at the same time several million eggs, although there are also such as navaga, which lays only a few thousand eggs.

Almost the majority of representatives of this family love cold water and lay eggs at a temperature of about 0 degrees and mainly in winter or at the end of winter.

After the appearance of fry, some of them remain in place, and some are carried away by the current, therefore, from the first days of their life, the fry of these fish begin to spread over the waters of the seas and oceans. Interestingly, haddock fry use jellyfish to hide from their natural enemies. Throughout their lives, representatives of this family carry out long migrations. This is due to some natural factors, such as sea and ocean currents, fluctuations in water temperature, including the availability of food.

Due to the fact that most of the cod species are distinguished by unsurpassed nutritional qualities, they are caught on a huge industrial scale. Every year, about 10 million tons of cod fish are caught and most of them are caught in the Atlantic Ocean. As a rule, the main mass is made up of the following types of cod:

  • Atlantic cod.
  • Pacific pollock.

Almost all of them lead a bottom lifestyle, so they are caught using deep-sea trawls. The meat of these fish is a popular food for its nutritional value. Their liver, which contains a huge amount of useful substances, is considered especially valuable.

Types of cod with photos and descriptions

As mentioned above, cod species number up to hundreds of different species of fish. Among them there are the most famous and most valuable, which will be discussed below.

This small fish is also called the "big-eyed cod". The cod lives at depths from 200 meters to almost a kilometer. It is easy to distinguish it from other fish species by its rather large eyes, which actually occupy a third of the head. During its life, the fish is able to grow up to a maximum of 15 centimeters, and most of the specimens are 9-12 centimeters long. The gadikul is found in the Mediterranean, as well as in the waters of Northern Norway. Occasionally found in oceans at very great depths. There are two types of this amazing fish:

  • North.
  • South.

They differ from each other, albeit slightly. Basically, they have a different number of fin rays and vertebrae, which is associated with their habitat.

This member of the cod family is found in the waters of the Mediterranean and Atlantic, as well as off the coast of Europe. This fish can be found in the Black Sea, off the coast of Crimea, where it is brought by the current after intense storms. It can grow up to 50 centimeters in length. The diet of whiting is made up of small crustaceans and small fish. Whiting itself supplements the diet of larger predators such as dolphins or katrans. Commercial catch of this fish is carried out exclusively in northern waters.

Merlang does not like great depths. After two years of life, the whiting can already lay eggs. At the same time, eggs are deposited at depths of no more than 1 meter, with a water temperature of at least 5 degrees.

Almost everyone knows this fish, since it can be found on almost all counters of fish stores. Pollock lives mainly in the north of the Pacific Ocean, because it prefers to live in cold water with temperatures from 2 to 9 degrees.

This fish almost always keeps in the water column, at depths of half a kilometer or more, and only at the moments of spawning does it move closer to the coast, to shallower areas.

Pollock begins to spawn after 3 or 4 years of age. The spawning period, depending on habitat conditions, can begin in winter and continue until summer. Pollock can grow up to 0.5 meters in length, and sometimes even more.

Alaska pollock belongs to one of the most numerous members of this family, which are found within the Pacific cold waters. This fish is caught on an industrial scale in huge volumes, therefore it ranks first in the number of fish caught today. Both the meat of this fish and its liver are nutritious and healthy.

Prefers to lead a near-bottom lifestyle. An exceptionally predatory fish that hunts at a depth of 500 meters. This predator can grow up to 2 meters in length, although there are mainly individuals up to 1 meter long.

They can lay eggs only at 8-10 years of their life. Her diet consists of small fish and other living organisms.

This fish is of serious commercial interest. Lives in the waters of the North Pacific Ocean, as well as the Chukchi, Okhotsk and Japanese seas.

Far Eastern navaga can grow up to 35 centimeters in length, although there are specimens that are larger, up to 50 cm in length, but very rarely. This fish prefers to be in the coastal zone, leaving it only in order to find food for itself.

At 2 or 3 years of age, it can spawn. Navaga spawns only in winter, at the lowest temperatures.

Populations of navaga are quite large, so they are caught in large batches. It is mined 10 times more than the White Sea navaga.

The main habitats of this fish are:

  • White Sea.
  • Pechora Sea.
  • Kara Sea.

It also prefers to be in the coastal zone, and during the spawning period it can go to the rivers. Despite this, the very process of throwing eggs is carried out only in salt water, in winter, at depths of about 10 meters. The female spawns eggs, which adhere firmly to the base of the bottom, after which they develop here for 4 months.

It reaches a length of about 35 centimeters, although there are representatives up to 45 centimeters in length. The diet of northern navaga consists of fairly small crustaceans, worms and small fish.

It is caught on a commercial scale in the autumn-winter period, since its meat has an unsurpassed taste.

It is the only member of the cod family found in fresh water. Like most codfish, burbot prefers cool water, which is why it is most often found in rivers and lakes in America, Asia and Europe.

The most numerous is the population of burbot in Siberian rivers, where it is caught both on an industrial scale and by amateur fishermen. Burbot spawns exclusively in winter, when the reservoir is covered with ice. In the summer, he prefers to hide in stones, holes or snags. With the onset of autumn, he begins an active lifestyle. Burbot is a nocturnal fish that does not tolerate sunlight. According to many anglers, at night it can be lured by the light coming from the fire.

Burbot grows in length up to 0.6 meters, with a weight of up to 1.5 kg. Despite this, there are specimens up to 1.2 meters in length and weighing up to 20 kilograms. The diet of burbot consists of larvae, crustaceans and small fish.

Haddock is found in the northern Atlantic and mainly in the coastal waters of Europe and America. Prefers to lead a near-bottom lifestyle. The body is characterized as laterally compressed. The body color is silvery, with a black lateral line and a black spot above the pectoral fin. The average length of fish is in the range of 50-70 cm, although there are individuals longer than 1 meter. It feeds on haddock on molluscs, worms, crustaceans, and also eats herring eggs.

At the 3rd or 5th year of life, females are already ready to throw eggs. The haddock fishery is quite well developed and, in terms of the weight of fish caught, it occupies a solid third place after pollock and cod. It is caught mainly in the North and Barents Seas. The catches are estimated at about a million tonnes per year.

It can grow up to 35 cm in length, although sometimes there are individuals up to 50 cm long. This fish grows too slowly.

It is found mainly in the northeastern Atlantic, at depths from 30 to 800 meters. The diet consists of fish fry, plankton and small crustaceans.

It is also harvested on an industrial scale and is also sold in many retail outlets.

Blue whiting

This member of the cod family is somewhat larger than the blue whiting. It can weigh up to 1 kg and grow up to 0.5 meters in length. Closer to the southern hemisphere, it prefers to be closer to the surface of the water, but the farther from these places it is, the deeper it is found, at depths up to half a kilometer.

It is mined on an industrial scale, making mainly canned food from it, although many housewives boil, bake and fry it.

It can also be easily purchased from the fishmonger.

Leads a gregarious lifestyle, being either in the water column or closer to the bottom. It grows in length up to 70 cm, although there are individuals up to 1 meter long, and sometimes even more. It lives mainly in the northern waters of the Atlantic. It migrates across the Atlantic over considerable distances: with the arrival of spring, it goes north, and with the arrival of autumn, it returns again to the warmer waters of the Atlantic Ocean.

Pollock is also caught in large volumes. It makes quite tasty canned food, called "sea salmon". This is due to the fact that saithe meat and salmon meat are characterized by a similar taste, but saithe meat is much cheaper.

This type of fish is already listed in the international Red Book and the Red Book of Russia. Atlantic cod grows up to 1.8 meters in length, although the average size is between 40-70 centimeters. Atlantic cod feeds on various crustaceans, molluscs, including fish.

Cod females begin to lay eggs at the age of 8-10 years, with a weight of 3-4 kilograms. She lives in the Atlantic Ocean. Highly prized for nutritious and healthy meats, including the liver, which is rich in healthy fats. Delicious canned food is obtained from cod. Many are familiar with such a delicacy as cod liver, which is used to make delicious sandwiches and other cold snacks.

In 1992, the government of Canada imposed a ban on the catch of Atlantic cod, since its numbers have declined sharply, which threatens the complete extinction of this type of fish.

This representative of the cod family differs from the Atlantic cod in its larger head and smaller body dimensions. It can reach a length of 1.2 meters, although there are mainly individuals measuring 50-80 cm.

This cod species lives in the Okhotsk, Bering and Japan seas. Does not carry out long migrations, adhering to the water area of ​​these seas and the coastline.

Begins to spawn at the 5th year of life. The total life expectancy is about 10-12 years. Each female is capable of laying several million eggs. It feeds on invertebrates and fish. It is also caught in huge quantities. Its meat is delicious in any form: it is salted, smoked, fried, boiled, baked and delicious canned food is made.

Useful properties of cod

Meat of these types is considered dietary, since the fat content in it reaches only 4 percent. In this regard, cod dishes have an excellent taste and are quite healthy for humans.

The presence of vitamins

The following vitamins are found in the meat of these fish species:

  • group B

The presence of trace elements

The meat of these fish contains useful minerals such as:

  • Potassium.
  • Phosphorus.
  • Calcium.
  • Magnesium.
  • Fluorine.
  • Sodium.
  • Manganese.
  • Copper.
  • Iron.
  • Molybdenum, etc.

When choosing one or another method of cooking fish, you should always remember that the task is to preserve the maximum of nutrients, without losing taste. This is only possible if the fish is eaten raw, boiled or baked. Naturally, the maximum of nutrients is preserved if it is consumed raw. To do this, it is simply salted or cooked in a marinade. To cook correctly, it is better to use ready-made recipes, of which there are a sufficient number. Still, it is better to resort to heat treatment. If you cook fish in the oven, it can turn out to be a very tasty and healthy dish. As a last resort, it can be fried and served along with a side dish and vegetables, although this will not be so healthy, and it can be hard on the stomach.

Representatives of cod are considered the most numerous species of fish inhabiting the waters of the Pacific and Atlantic oceans. Due to the fact that the meat of these fish is not only tasty, but also healthy, they are caught at a tremendous pace, which is reflected in the indicators associated with millions of tons annually. If this continues, then our children may not see most of the seafood on their tables.

The liver of these fish is no less valuable, since many useful substances accumulate in it. Since the meat is not fatty, it can be consumed by almost all categories of people, especially those who have managed to gain excess weight. Only personal intolerance to seafood can become a real obstacle to eating cod fish.

In our article we will tell you about the cod family. All its members have tasty and healthy meat recommended for dietary nutrition. The Atlantic cod has the best characteristics. But other representatives of this family, for example, haddock, hake, blue whiting, pollock, pollock, are popular and beloved on our table.

Lots of meat, few bones

The habitat of fish of this family is the seas of the Northern Hemisphere. They are especially common in the Atlantic Ocean. The family of cod fish includes individuals with large heads, small bones, small scales and large liver. Many of them are mined commercially.

The chemical composition of these fish includes many useful elements: vitamins, fatty acids, phosphorus, iodine, calcium. Their meatiness and low fat content allow them to be used in dietary nutrition. There are many ways to cook fish. Cod fish are good in fried, stewed, smoked and dried form. There are many recipes that are used by ordinary housewives and restaurant chefs.

Most useful

Atlantic cod is a well-known member of this family. These fish can grow up to 1.8 meters in length, but are usually caught before they reach that size. It is distinguished from other fish by a fleshy tendril on the chin, olive-brown scales and a white belly. Cod is found in the Atlantic Ocean but is also found in the White and Baltic Seas. Not only dense and white meat is considered useful, but also from which oil is prepared for medical purposes.

If you take such a substance regularly, you can improve your well-being, mood, get rid of joint diseases, and increase intellectual abilities. But it is better to use fish caught in ecologically clean places, since cod can accumulate mercury and arsenic, which means that excessive consumption of it in food can be dangerous.

Delicate fish

The family of cod fish also includes haddock. Its meat is tasty and more tender than that of cod. The body of this fish, dark gray with purple patches, is flattened from the sides. The belly is white or milky-silvery. There is a dark spot between the pectoral and dorsal fins on both sides. Haddock is caught in the Atlantic and Arctic oceans. This fish prefers sea water, therefore, it is almost never found in the Baltic Sea due to its desalination. Haddock most often lives near the bottom at a shallow depth. There she looks for her usual food - bottom mollusks, worms, echinoderms, fry and eggs of other fish.

It is worth noting that the haddock diet includes blue whiting, which also belongs to the cod family. This fish feeds on crustaceans and fry. It lives at a depth of 180-300 meters. Blue whiting is often found on the shelves of our stores. Someone eats it themselves, but most often this fish is bought for cats who simply adore it. In addition, the cost of blue whiting is low compared to other members of the cod family.

Useful and inexpensive

Another favorite fish of our fellow citizens is the Far Eastern pollock. It is inexpensive and always available in stores. But you shouldn't treat her with disdain. Like all members of the cod family, it is nutritious and healthy. Of course, her meat is a little dry, but a good housewife will find a way to save her from this shortcoming. Eating pollock helps to regulate metabolism, the amount of sugar in the blood. The meat of this fish has antioxidant properties, is rich in iodine and chromium. Eating 100 grams of pollock per day, you get a daily intake of iodine. It is mined in the Pacific Ocean, where it is found in huge numbers.

Not only at sea

Burbot also belongs to the cod. It predominantly lives in fresh water. Although there are also These fishes have a long body, slightly flattened laterally, a flat head, antennae on the chin and upper jaw. The sea burbot lives in the Barents Sea, near Iceland, the British Isles and even off the coast of North America.

These fish are of two types - white and red. Red meat has the best taste; it contains a large amount of iodine, although the meat itself is rather dry. However, this does not make it any less valuable. River burbot meat, on the contrary, is tasty and soft. Its liver is also considered a delicacy. The trace elements contained in this fish have a positive effect on vision, intelligence and the nervous system. The habitat of burbot is wide enough, it is also widespread in our country. It is best to catch burbot in cold water in inclement weather, then it is most active.

Other cod

The cod family includes whiting. It lives in the North Atlantic Ocean, in the Barents Sea, off the coast of Iceland and Portugal. Sometimes found in the Black Sea. This fish has a pleasant taste and is not inferior to cod or haddock. They catch meenok off the coast of Murmansk, Norway, the Faroe Islands, Iceland, although this fish is not widespread and is not caught on an industrial scale. The Arctic Ocean is inhabited by the Arctic cod. This small fish prefers to live in cold water. The Arctic cod feeds on crustaceans, zooplankton, fry of other fish. She, like other representatives of codfish, has a small tendril under the chin. Pollock has the same distinctive feature. This fish can grow up to 1 meter in length. Other small cousins, crustaceans, serve as food for it.

In our article, you learned about the cod family. Surely many of the names turned out to be familiar to you. After all, this fish is a frequent guest on our tables. It turns out that you can save a lot if you buy pollock, haddock, blue whiting more often than cod. They are just as useful as other members of this family, but are cheaper.

Haddock is a valuable commercial marine fish that lives in the North Atlantic and the Arctic Ocean basin. It belongs to the cod family and prefers seas with high salinity. We will tell you more about this type of fish and its culinary value.

Description

Haddock - large sea fish, the weight of which can be up to 4 kg. In rare cases, specimens of 15 kg come across. The body is fusiform, dark gray with a characteristic lilac tint. The back is usually darker and the belly is milky white. Haddock can be distinguished from other codfish by its characteristic dark spots on the body.

Its habitat is in the northern seas, but this fish does not like extreme cold, therefore it is rarely found in waters where the temperature is below 6 degrees Celsius. She prefers the bottom of reservoirs, choosing depths from 30 meters to one kilometer.

Haddock grows for 14-15 years becoming sexually mature by age five. The size of this fish largely depends on its habitat. In the Barents and Northern Seas, it is found in relatively shallow waters, so it is fished at depths of up to 50 meters. In these seas, haddock usually does not grow more than 5 kg. Whereas to the north, where the food supply is larger, real giants weighing 10-15 kg can come across. Moreover, such large specimens prefer to stay at great depths of 500-1000 meters.

Composition and calorie content

In shops you can find fresh frozen haddock, smoked or salted. Haddock fish has a delicate white meat with a pleasant taste. One of the features of this fillet is its low calorie content, which is 70 kcal per 100 g of product. That is why haddock is often recommended to be included in various weight loss diets.

Haddock fillet contains the following trace elements:

Important. This fish is rich in nutrients, incl. selenium, which protects the human body at the cellular level from the onset of cancer.

Also haddock fillet contains a variety of vitamins, including A, E, C, PP and vitamins of group B. That is why regular consumption of this fish has a positive effect on human health, improving the state of the immune system, preventing the development of various diseases.

How to choose and store haddock

Attention... Only fresh chilled meat retains all its flavor properties. Therefore, when choosing, you should give preference to fresh or chilled fillets.

Cooking use

Haddock meat is a dietary product that is equally suitable for adults and children. Due to its low calorie content, you can include such fish in various weight loss diets. At the same time, fillet contains various trace elements and vitamins that are vital for our body. This fish is not recommended for those people who have a negative reaction to protein or are allergic to seafood.

You can cook it in the oven or on the grill. Delicious canned food and salads are made from the liver. You can also fry the fillets by rolling the meat in breadcrumbs or flour. Haddock makes an excellent fish pilaf, hodgepodge or fish soup. Fillet and pate can be used as filling for pies. You can make a tender steak from fillets. You can fry and bake it directly with the peel, which contains numerous beneficial trace elements.

Important. To preserve all the nutrients in the meat, fry it in a ceramic pan without adding oil, and bake or stew in foil.

conclusions

Haddock is a commercial fish, belonging to the cod family. The meat of this fish contains numerous trace elements and vitamins necessary for the body. Haddock is of great gastronomic importance due to its excellent taste and affordable cost. You can easily find numerous recipes for preparing this fish, which will allow you to prepare delicious dishes that will become the basis of your proper diet.

The family of cod fish consists of almost 100 species that live mainly in the waters of the Northern Hemisphere. All of them, with the exception of burbot, are representatives of the marine ichthyofauna. In addition to the usual cod, navaga, haddock and pollock, the order of cod-like fish includes such exotic fish for the Russian consumer as menek, gadikul, molva.

Some species are the object of commercial production, others are of interest only to amateur anglers.

Common features and distinctive features

The main signs of belonging to the cod family - a fleshy whisker on the lower jaw and spots of various sizes and shapes scattered throughout the body - are not found in all representatives of the order. In some fish, the scales are silvery, and the antennae is absent or poorly developed.

But other "family traits" (pictured) are present in almost all fish of the family.

A sign of the cod order is large eyes on a disproportionately large head and a light longitudinal stripe along the body

The characteristic features of the family include the absence of spiny rays in the fins and large gill openings. The body of codfish is covered with small cycloidal scales.

The table contains a list and a brief description of the commercial and most nutritionally valuable cod fish.

There are several types, the most common are Atlantic cod and Pacific cod (subspecies differ in size and range) It has a well-defined large mouth and several dorsal fins. The color is from dark brown to light olive, there are small spots all over the body. Pacific cod have a larger head than Atlantic cod The length of the Atlantic cod is from 70 cm to 2 meters, the Pacific species reaches 1.2 m Pacific cod is common in the Bering, Japanese, and Okhotsk seas.

In addition to commercial species, the list of fish of the cod family includes popular objects of amateur fishing:

  • polar or polar cod, a small fish (average length 25 cm) living in the Arctic Ocean. They catch her in the White, Barents Seas;
  • gadikul (another name - big-eyed cod), the smallest representative of the cod reaches a length of 12 cm. A distinctive feature is huge eyes that occupy a third of the head. Antenna is absent. Sides are silvery with dark small specks. Often, the gadicle is used as bait for catching other cod fish;
  • tomcode; the genus includes 2 species, differing in size and habitat: the Atlantic tomcod (average length 35 cm) and the Pacific tomcod or American cod (30 cm long). In Russia, it is caught in the Barents Sea, off the coast of Murmansk. In the USA and Canada it is a sport fishing target;
  • lusca (chaplain, French tresochka), a beautiful copper-brown fish with yellowish sides, decorated with 4–5 transverse dark stripes. Average length 30 cm


The usually gray, dull color of the back of the gadicle can vary depending on the habitat

Common burbot

In a separate row, burbot (the outdated name is less) is not by chance. It is the only freshwater cod species.

Fish feel comfortable in cold rivers and lakes. The largest population is widespread in the northern waters of Russia. In smaller numbers, the freshwater predator can be found in the rivers flowing into the Black and Caspian Seas. Northern burbot is larger than its southern counterpart. Its average weight ranges from 3–6 kg with a length of up to 80 cm (in warm water bodies it rarely exceeds 600 g).

Note! Burbot is always looking for the coolest place in the river; it often settles in the area of ​​springs. In the absence of underwater springs, the fish chooses snag, deep pits or large stony placers as a habitat.

The color of the fish largely depends on the type of bottom (pebbles, sand, clay) and the degree of transparency of the water. A brownish or dark brown color is considered traditional, which becomes lighter as the fish grows and ages. The belly of the burbot is olive, the fins are dark gray, almost black. Like most cod fish, burbot is decorated with dark, randomly scattered spots.


While in ambush, the burbot puts forward a wiggling whisker that attracts small fish

A flat head with small eyes, three mustaches (on the chin and along the edges of the upper jaw), mucus covering the body make the burbot look like a catfish. It is not difficult to distinguish fish. In burbot, the body is covered with cycloid scales (the catfish has no scales). Burbot is a nocturnal predator. The structure of his senses is designed for hunting in complete darkness.

Note! The fish has exceptional hearing and is quite curious. Having caught an unusual sound, the burbot rushes to the source of the noise, overcoming, at times, a considerable distance. This behavior is often used by fishermen.

The diet

Fish belonging to the cod order, with a few exceptions, are predators.

At a young age, they feed on benthic invertebrates: crustaceans, shrimps, worms. As you get older, your diet changes. Now it is based on small fish, including representatives of its own family. For example, cod actively feeds on young pollock. Blue whiting often becomes a prey for haddock.

Small representatives of the order (gadikul, Arctic cod) feed on plankton and bentonic crustaceans, but sometimes they diversify the menu with fry or caviar of their fellows.


Strong fast pollock hunts in packs. Jamb noise is sometimes heard on the water surface

Cannibalism is very common among cod fish: their own juveniles often become their prey.

Interesting fact! The accumulated fat is deposited in the liver of cod fish, which, due to this, acquires a lot of useful properties. Saturated with vitamins, macro- and microelements, essential amino acids, the liver is useful in the prevention and treatment of a wide range of diseases.

Reproduction

The overwhelming majority of the family reaches puberty after 3 years of life. Large individuals (cod, moth) begin to spawn when they reach 6–8 years of age. Spawning occurs in late winter or early spring. Codfish are very prolific. Large individuals can lay up to 9 million eggs. Navaga spits up to 90 thousand eggs, small representatives of the family - no more than 6 thousand. The eggs and larvae that appear are predominantly pelagic. By the current from the spawning site, they are carried over considerable distances.

The fry spend the first year of life in shallow water near the coast. They often hide under the jellyfish bell. As they mature, the juveniles move to depths and begin to make seasonal migrations.

Interesting fact! Only males are born from eggs laid by blue whiting. As they mature, some fry show signs of females. By the age of maturity, the ratio of males and females to blue whiting becomes equal. By the end of life (fish lives on average for 20 years), all individuals gradually turn into females.

Cod fish are a priority object of domestic and world fishing. They are prized for their tasty, low-calorie meats and low bone content. Affordable price plays an important role.

Codfish are a welcome trophy for fans of sea fishing. Trolling and plumbing are the most popular methods. Representatives of the family are successfully caught from the shore using spinning or bottom tackle. Either way, fishing for cod fish will be a lot of fun.
