The B altic species of salmon is one of the most valuable among commercial fish. Its popularity is due to its high taste and dietary qualities. This gave impetus to the development of fish farms that grow various types of salmon both for sport fishing and for the sale of fresh weight fish. We will consider some photos of the B altic salmon and its description in this article.

Lifestyle and longevity

Salmon is an anadromous fish that lives both in freshwater reservoirs and in marine, oceanic s alty environments. The salmon living in the B altic Sea spends the main part of its life there, but goes to freshwater reservoirs to procreate. This occurs when the individual reaches the age of five. Salmon chooses to spawn in calm and shallow places with a rocky or sandy bottom.

When the B altic salmon starts to spawn, its color takes on a darker shade. Because of this feature, a kind of hook becomes noticeable on the jaw of males. In females italso present, but not as pronounced. During spawning salmon food is extremely scarce, which leads to some depletion. The color of the meat turns pale, and the fat content is significantly reduced, as a result of which the fish loses its taste and quality values. Therefore, catching B altic salmon, as well as other members of the family, during the spawning period is prohibited.

The average life span of salmon ranges from 9 to 10 years, but some individuals in the wild can live up to 25 years.

Diet

B altic salmon spend most of their lives in the sea. It feeds mainly on herring and various crustaceans. Rarely eats gerbil. When salmon go to spawn, they stop feeding.

Young specimens most often feed on zooplankton. In addition, salmon's favorite delicacy is smelt and vendace. It is to search for this delicacy that he regularly moves around the pond. Often, the B altic salmon comes close to the shore to search for insects that live in the coastal strip. They also make excellent food for juveniles.

Salmon breeding

In most cases, salmon spawning takes place in fresh water. It can be both the sources of rivers and small streams. An important factor is the availability of running water. This is explained by the fact that the ancestors of modern salmon were fish that lived exclusively in fresh water. Thanks to a long evolution, the ancient ancestors of salmon were able to adapt to life ins alt water of oceans and seas.

The salmon spends most of its life in its permanent habitat - the sea. He is actively eating and gaining weight. After 5 years, the fish that has reached puberty goes to spawn. It is noteworthy that the spawning grounds were not chosen randomly. The salmon goes exactly where it was born.

In spawning grounds, the appearance of salmon undergoes significant changes. The shape of the body and its shade change. The color changes from silver to bright with black spots. The jaws are also highly modified. In males, they become hook-shaped, while the bend of the lower jaw is directed upwards, and the upper - downwards. When spawning, salmon also undergo strong changes in the stomach and liver, which makes their body loose and lean. Therefore, it loses its taste (as mentioned above).

What B altic salmon looks like - key features

Scientists have proven that the ancestors of salmon appeared during the Mesozoic era, as evidenced by a number of findings. In modern times, this type of fish looks very similar to the herring family. The length of adult B altic salmon can reach from several tens of centimeters to one and a half meters. The mass, in turn, can also fluctuate. The body of the fish has an elongated shape and is covered with silvery round scales. The fins are not prickly and are located in the middle of the abdomen. A notable feature of all salmonids is their small adipose fin.

Salmon farming

Thanks to mypopularity and high taste, this fish is quite expensive. Therefore, more and more fish farms are breeding salmon, which brings them a good income. This process is facilitated by the fact that fish return to spawn in fresh water. For breeding, fish factories are used, which are built mainly near rivers. Fish going to spawn are caught, eggs are collected and fertilization is carried out.

The obtained fry are reared and released into the rivers. They go to the sea, where they grow and feed, and after a few years adults return to spawn in the river, which are caught here.

Useful properties of salmon dishes

Salmon is a fish with tender red fillets that have a great flavor that remains regardless of the cooking method. Lightly s alted fillets are the most popular. It is a completely independent finished product, added to both hot dishes and cold snacks. B altic salmon fillet is rich in easily digestible protein, and at the same time it does not contain carbohydrates, which makes it a he althy food. In addition, salmon fillet contains vitamins A, B, C, E, PP, a certain amount of calcium, sodium, phosphorus, iodine and many other microelements important for the body.

The systematic use of salmon in food contributes to the normalization of weight and metabolism. Scientists have proven that, thanks to a balanced set of trace elements, dishes prepared fromsalmon, have a positive effect on the functioning of the nervous system and reduce the risk of oncology.
